The TrutzBox® will now make your Internet more secure. It has the effect that you cannot be observed while e-mailing and cannot be spied on while surfing. You leave fewer traces on the Internet and you are less traceable. With the TrutzBox ® you strengthen your privacy.
The TrutzBox® is the security center of your home network. It controls incoming and outgoing Internet traffic. With the TrutzBox® you determine which information the devices connected to the Internet in your home network may disclose.
With the TrutzBox® you can control the Internet connections of your
- Internet devices at home, like computers, tablets, smartphones,
- mobile Internet devices on the move, such as laptops, tablets, smartphones,
- Internet-enabled devices, such as television, house control (e.g. roller shutters, heating), toothbrush, refrigerator, etc.
The TrutzBox® will make the lives of criminal Internet hackers, professional data traders and secret services, which have been observing you while surfing and use your data for their own purposes or commercially, more difficult to a previously unknown extent.
Comidio TrutzBox® offers optimal protection of your privacy through
- automatic end-to-end encryption of your e-mails,
- traceless surfing the Internet,
- maximum protection for your children,
- Firewall and virus protection,
- easy operability,
- cost-effective use,
and thus delivers optimal anonymity.
The TrutzBox® offers plug and play settings and is already optimally configured for most requirements at the factory. Special personal requirements are set via the easy-to-use user interface.

1.4 TrutzBox with or without (own) WLAN?
The WLAN module of the TrutzBox is required if a mobile device is to be controlled via the TrutzBox®. This is then connected directly to the network of the TrutzBox (= its WLAN).
There are basically two ways to connect devices to the TrutzBox®:
| Case 1: | PC 1 is connected to the Internet router via WLAN or network cable (dashed yellow).
|
| Case 2: | PC 2 is connected to the TrutzBox® via WLAN or network cable (green dashed). All Internet traffic (surfing) automatically passes through the TrutzBox®.This mode is called |
To use the TrutzBrowse and TrutzContent functions (secure surfing for and protection of minors), it can be decided for each device whether it should be left on the network of the Internet router (e.g. Fritzbox) (proxy mode) or connected to the TrutzBox network (transparent mode).
The aim is to connect as many or all devices as possible in the home network directly via the TrutzBox® (i.e. in "transparent mode").
It is advisable to reach this state step by step.
Therefore, you should start "small" at the beginning and gain experience in "proxy mode" by not changing anything on your home network, i.e. the devices initially remain on the Internet router.
You can also intentionally surf in a browser (e.g. Firefox) in proxy mode while surfing in parallel in a second browser (e.g. Chrome) without protection.
For example, you can track the influence the security slider has on unprotected access in various positions (e.g. effects on advertising offers shown).
If you have sufficient experience in proxy mode and would like to gain additional security, you can gradually connect devices in transparent mode by connecting them directly to the TrutzBox® via WLAN (or network cable).
[Since there are occasional exceptions in which website use is not possible even with SliderLevel 10 (TrutzBox set to "pull-through"), it is recommended to operate a browser-based client device in proxy mode, so that the TrutzBox can be switched off as a proxy in the browser of this client device if necessary. This allows the browser of this device to access the Internet directly via the Internet router (bypassing the TrutzBox). After the exception has been made, the TrutzBox should be activated again in the browser as a proxy].
This means that the TrutzBox can also be operated safely without a WLAN module and the WLAN module can be added later if required.
The other TrutzBox functions, such as Webmeeting, Mail, Chat and Remote Access, work in both modes unaffected by this.
To change from transparent mode to proxy mode or vice versa, please proceed as follows:
- Shut down PC or device (= switch off by software).
- If previously connected to TrutzBox, now connect to the Internet router or vice versa.
- Switch on/restart the device (now the device automatically receives an IP address valid in this network area).

3 TrutzBox® Setup (for TrutzBox® Administrator)
This chapter includes
- Start-up of the TrutzBox®
- Set-up of the TrutzBox®
The aim is to connect as many or all devices as possible in the home network via the TrutzBox®.
However, this only happens after setting up according to the manual.
After the TrutzBox® is connected to the Internet router, start "small" by entering the TrutzBox® as "Proxy" (= deputy, quasi "doorman") in a browser of a connected PC and thus controlling the TrutzBox® the incoming and outgoing Internet traffic of this connected PC.
After completing this quick start, the user can
- surf without tracks (at least with few tracks) with presets,
- encrypted email via web access and
- use the proposed filter lists for child and youth protection.
Once this state has been reached, further devices should be connected to the TrutzBox® in a controlled manner.
Devices for which a proxy can be set up
Devices for which a proxy can be configured (e.g. browser on PC or, if available, on TV set) should first be connected to the Internet router via WLAN (or network cable) and the TrutzBox® should be entered as the proxy.
Once you have gained experience in this way, you can connect the devices directly to the TrutzBox® via WLAN (or network cable).
Devices for which no proxy can be set up
Devices for which no proxy can be set up (e.g. refrigerator or toothbrush) should be connected to the TrutzBox®; then the communication characteristics can be monitored and, if necessary and controlled, external communication can be permitted.

The TrutzBox® checks if there are current updates; if yes, they will be downloaded now (1).
Please note that this process can take up to 30 minutes.
-> Table of Contents (of this manual)
The updates are completely downloaded when the window " Abschluss der Einrichtung " appears.
Click directly - without clicking on steps 1 & 2 - on the "Fertig" button to end the setup process.
(Step 1 follows only after the installation; Step 2 can now be saved due to the further development of the TrutzBox).

Then the TrutzBox user interface appears automatically and shows you:
Now the quick start is complete.
-> Table of Contents (of this manual)
After downloading, your TrutzBox® is ready for operation.
The next step is to
- set up the TrutzBox as a proxy; see Chapter entitled "Connecting the device to the TrutzBox" and
- import the root certificate (if you want to use other devices with a browser in addition to your PC); see the "Certificates" chapter.
On every other device with a browser that uses the TrutzBox®, the certificate
- if browser is Firefox: must be imported into the Firefox certificate management,
- if browser is not Firefox: must be imported into the certificate management of the other browser, and thus automatically into the certificate management of the operating system. (see chapter "Certificates").
To use TrutzMail or TrutzChat, the TrutzBox certificate must also have been imported into the certificate management of the operating system.
The TrutzBox certificate only needs to be imported once into the certificate management of the operating system and is then available there for
- all non-Firefox browsers and
- TrutzMail and
- TrutzChat.
If you do not import the certificate into the browsers and notify the mail system, you will be prompted for security confirmation each time you open it.
Therefore it is recommended to download the TrutzBox® certificate from the TrutzBox® to the device with browser and import it into the browser afterwards.

3.2.5 Disable IPv6
The TrutzBox works exclusively with IPv4 addresses.
If your TrutzBox is not connected to the router or your terminal device (e.g. PC) cannot reach the TrutzBox, one reason for this may be that the router assigns IPv6 addresses. To avoid this, it should be ensured that the router assigns IPv4 addresses.
To disable IPv6 addresses, proceed as follows:
In the FRITZ!box user interface, call up "Internet".

4 Use of the TrutzBox® (-> for users)
The TrutzBox® is delivered by Comidio with security settings suitable for everyday use, so that even inexperienced users can email and surf immediately protected and without a trace.
The following sections describe the functions and options that the inexperienced user can use immediately after setting up TrutzBox.
These include:
- TrutzBrowse: Traceless surfing through modified, incomprehensible browser profile data.
- TrutzMail: End-to-end email service with encrypted content and encrypted metadata.
- TrutzContent: Maximum protection for children and young people by using filter lists to block inappropriate websites.
- TrutzRTC': Real-time communication with TrutzChat (Messaging) and TrutzMeeting (Audio and Video Conferencing Service)
- TrutzBase: Use of modern virus protection, firewall and intrusion detection systems
4.1 Traceless Surfing - TrutzBrowse
Independent of browser (e.g. Mozilla Firefox, Chrome, Internet Explorer, Safari, etc.) and operating system (Microsoft windows, Apple iOS, Linux), the TrutzBox helps to avoid data tracing while surfing.
Use your browser as usual (in the following as an example with windows 7 and Firefox).
4.1.1 TrutzBrowse in standard operation
The TrutzBurg symbol in the upper right corner of the website indicates that TrutzBrowse is activated with the security settings. With the above setting, the TrutzBox (symbol: TrutzBurg) and the Tor network (symbol: onion) are activated.
The color of the TrutzBurg shield indicates the setting of the security slider for this URL; green = level 1 = highest security level; red = level 9 = lowest security level.
If there are operating elements on the website which are hidden by the TrutzBurg and can therefore no longer be operated, the TrutzBurg can be moved to another corner of the browser window.
For touch screens, simply touch the symbol for longer than 1s.
After clicking on the TrutzBurg, the security slider and four further functions are available.
The Security-Slider can be set to 10 security levels (Level 1 = highest protection up to Level 9 = lowest protection; Level 10 = for this website the TrutzBox is switched off). From level 1-9, the user can make the settings himself. If set to level 10 (TrutzBox protection is disabled), only the administrator can reset the level for this website.
On delivery, the security slider is set to "highest security level" (level 1, green, far left).
If the website shows malfunctions, e.g. because it wants to store a cookie, the user can gradually deactivate individual security and anonymisation measures by dragging the security slider to the right (towards red) in order to restore the website's functionality.
However, the security level should only be reduced for trusted websites.
Click on "Details" to see a list of all web accesses accessed from this website.
Blocked HTTP calls are marked by a "red crossed out circle“.
The overview also shows the HTTP headers that have not been completely blocked (marked by a "green tick in a green circle").
This makes it obvious which data was transmitted from the browser to a Web server ("Request" tab) and which data went from a Web server to the browser ("Response" tab).
Depending on how the TrutzBox® is configured for the current position of the Security Slider, certain HTTP header data may not be transmitted to the web server at all (blocked headers) or may be changed (replaced headers).
On the left, the HTTP calls are listed, which are automatically called in the background - without the user's active intervention - in addition to the web page called up by the user (here: www.krone.at). On the right under "Details" you can see which header information has been blocked or replaced.
Click on one of the HTTP calls listed on the left to obtain additional information on this.
Set a check mark to " Nur Blockierungen anzeigen ", then only the blockings are listed.
-> Table of Contents (of this manual)
4.1.2 TrutzBrowse for experts
The TrutzBox® monitors web access and is thus able to prevent unwanted data traffic. The TrutzBox® distinguishes whether a device or a user calls up a web page directly or whether a web server - after the deliberately called up web page has been loaded - contacts further web pages and loads them without the user's knowledge and without his consent.
The TrutzBox® offers two different basic functions for this purpose:
1. TrutzContent:
A content filter that prevents a device or user from directly accessing a particular Web page. Examples of unwanted calls:
- A young person wants to load a website with content harmful to young people.
- An Internet device unnoticedly calls up a web page in the background without a user deliberately initiating it. These can be TVs, washing machines or game consoles (if they are connected to the Internet), or even the standard Internet browser of the user's PC, which in turn contacts Mozilla or Google or the server of a plug-in provider independently, for example.
The TrutzBox® checks if the contact to such a server is allowed and blocks the connection to this server if necessary.
2. TrutzBrowse:
A user or an Internet-enabled device has validly accessed a Web page. When loading the page, however, this website contacts other web servers (often commercial data trackers) that may be interested in the user data. TrutzBox® monitors calls to other web servers that are indirectly contacted without the user's knowledge during the loading process of the deliberately accessed web page.
In both case 1 (TrutzContent) and case 2 (TrutzBrowse), the TrutzBox® compares every web page called up with the web pages (filter lists) known to it. Comidio provides approx. 110 filter lists covering 55 different Internet topics. These filter lists are updated regularly. The TrutzBox® Administrator can add own filter lists if required.
Approach of the TrutzBox®:
Wenn ein Internet-Nutzer eine Webseite aufruft, dann prüft die TrutzContent Funktion zunächst, ob der PC und/oder der Nutzer, der diesen Webseitenaufruf angestoßen hat, diese Seite überhaupt aufrufen darf. Soll diese Webseite gemäß den Filterlisten blockiert werden, dann bekommt der Internet-Nutzer im Browser eine Fehlermeldung angezeigt.
If the website can be accessed, the TrutzBox® allows the data from the web server to pass to the browser, but it monitors each call to other web servers that the website then contacts automatically. Usually a website loads additional content from many other web servers. For each contact with a web server other than the originally called web server, the TrutzBox® checks whether this later called web server is in a filter list group "TrutzBrowse". If it is listed there, the connection to this server will be blocked.
This prevents data tracker calls that are programmed into most websites, and data trackers cannot spy on user behavior.
Each time a Web server is granted (permitted) access, information is sent from the Web browser to the Web server via the HTTP header (http request header). Without the TrutzBox® the browser would then deliver this requested data to the web server. This can be very personal data, such as which other pages you have recently called up, are you currently logged on to Facebook or how exactly does your PC/browser configuration look in order to recognize you on further calls. The HTTP header filter also controls the setting and retrieval of cookies
With its TrutzBrowse function, the TrutzBox® is thus able to control the entire HTTP data exchange on the Internet and to block or falsify these HTTP header data as long as they are not absolutely necessary..

4.1.2.1 Handling SSL connections
The proxy can only break (and analyze) an SSL-encrypted connection between a program and a server if the SSL key has been signed by one of the known certificate authorities. Here are two cases where breaking the encrypted connection does not work:
- if an app establishes an encrypted connection to the server, but the key used is a self-generated key and has therefore not been signed by an official certification authority. If the app is a browser, the user is asked if he accepts the server. If the app is not a browser, the user cannot be requested.
- if the client is authenticated. In this case, a key is usually programmed into the client.
In all cases where the SSL connection cannot be broken, the SecSlider is automatically set to L10 and thus the data transfer is no longer analyzed. This ensures that apps still work "without manual intervention". The user (or the TrutzBox administrator) can deactivate this automatic feature in the "Configure filter" menu with the option "If SSL errors occur, automatically deactivate filtering for the selected domain". The data connection is nevertheless displayed in "Status" for checking purposes. Since this automatic activation only becomes effective if the server has not yet been set in the slider table, this automatism can also prevent a single server if the SecSlider is set manually to any value for this server.

4.1.3 Install proxy switch for activating/deactivating the TrutzBox® in the browser
Attention: Switching the TrutzBox on and off as a proxy (="Call forwarding") only makes sense if the browser to be used (or the terminal device used, e.g. PC) is operated in "proxy mode", i.e. the PC is connected to the Internet router (and not directly to the TrutzBox).
If the browser to be used (or the end-device used, e.g. PC) is operated in "transparent mode", i.e. the PC is connected directly to the TrutzBox (and not directly to the Internet router), I do not need a switch, as the PC is constantly protected via the TrutzBox and switching a proxy on or off makes no difference..
As is known, it is possible to activate or deactivate the TrutzBox® functionality "TrutzBrowse" by activating/deactivating the "PAC" file in the browser settings.
If you want to save yourself these "efforts", you can also install a "proxy switch" (in the form of a downloadable "Add-On" = additional function) in the respective browser and then easily activate or deactivate the TrutzBrowse functionality by simply pressing or selecting it in the browser header line.
The following shows the installations of two proxy switches:
- for Browser "Firefox": Add-On „Proxy Switcher“ and
- für Browser "Chrome": Add-On „Proxy SwitchyOmega“.
Of course, other proxy switches can also be implemented and used.
4.1.3.1 Proxy Switch for "Firefox" Browser
Attention: Switching the TrutzBox on and off as a proxy (=" Redirection") only makes sense if the browser to be used (or the end-device used, e.g. PC) is operated in "Proxy Mode", i.e. the PC is connected to the Internet router (and not directly to the TrutzBox).
If the„FoxyProxy Standard“ add-on is implemented, the user can activate and deactivate the "Trutzbox" proxy and thus the TrutzBrowse function by clicking the Proxy Switcher button (orange fox head) in the browser header.:
- to switch on: by clicking on the symbol "crossed out, orange fox head" the FoxyProxy selection window appears; there click on the green line "Use proxy Trutzbox for all URLs (ignore patterns)'" and the proxy is switched on and the symbol "orange fox head" appears.
- to turn off: by clicking on the symbol "orange fox head" the FoxyProxy selection window appears; click on the red line "Turn Off All Proxies" and the proxy is switched off and the symbol "crossed out, orange fox head" appears.

4.3 Protection of minors - TrutzContent
The TrutzBox® monitors web access and is thus able to prevent unwanted data traffic. The TrutzBox® distinguishes whether a device or a user calls up a web page directly or whether a web server - after the deliberately called up web page has been loaded - contacts further web pages and loads them without the user's knowledge and without his consent.
The TrutzBox® offers two different basic functions here:
1. TrutzContent:
A content filter that prevents a device or user from directly accessing a particular Web page. Examples of unwanted calls:
- A young person wants to load a website with content harmful to young people.
- An Internet device that unnoticedly calls up a web page in the background, without a user deliberately initiating it, calls up a web page in the background. These can be TVs, washing machines or game consoles (if they are connected to the Internet), or even the standard Internet browser of the user's PC, which in turn contacts Mozilla or Google or the server of a plug-in provider independently.
The TrutzBox® checks if the contact to such a server is allowed and blocks the forwarding if necessary.
-> Table of Contents (of this manual)
4.4 Real time communication- TrutzRTC
As part of the updates, two real-time communication functions are implemented on the TrutzBox® (without the customer's active involvement and free of charge):
- TrutzChat = XMPP Service for messaging and, depending on the client used, other functions such as audio, video communication, file transfer, screen sharing ...
- TrutzMeeting Audio and video conferencing service: Server on which you can connect to a browser that supports the WebRTC standard and which is capable of connecting several audio or video conference participants.
TrutzRTC runs automatically, does not need to be configured and has no user interface on the TrutzBox.
-> Table of Contents (of this manual)
4.4.1 TrutzChat (XMPP Service)
It works similar to e-mail. The XMPP server on the TrutzBox manages users, their online status and their messages. If a message is to be sent to a subscriber who is not on the same server (i.e. on a different TrutzBox) as the sender, the target server is determined, contact is made with it and the message is delivered to this XMPP server. The same applies not only to messages but also to other functions, such as Presence status
Comidio has extended the XMPP server on the TrutzBox so that it is able to use the same security functions as those used by TrutzMail. This means:
- Communication partners are addressed with the TrutzMail address.
- The connection establishment and the message transmission with users on another TrutzBox, take place via Tor hidden services.
- The same certificates and keys are used to encrypt messages and authenticate the TrutzBox of the communication partner as for TrutzMail.
Once created, TrutzMail addresses can also be used directly for messaging.
Structure of the XMPP service between the TrutzBoxes
-> Table of Contents (of this manual)
4.4.1.1 preconditions:
In order to use the TrutzChat service, a TrutzMail address' and an XMPP-enabled program on the mobile device (PC or mobile) are required. Chat programs that support the XMPP protocol are available for all common operating systems with different features.
These links give a good overview of available XMPP clients:
- https://de.wikipedia.org/wiki/Liste_von_XMPP-Clients
- https://de.wikibooks.org/wiki/XMPP-Kompendium:_Einrichtung
- http://xmpp.org/software/clients.html
The individual selection depends partly on requirements, partly on taste.
Comidio uses the following clients:
| Apple Macintosh | Adium (https://adium.im) |
| Microsoft Windows | PSI (http://psi-im.org) |
| iOS | ChatSecure (https://chatsecure.org) |
| Android | Xabber (https://www.xabber.com/) |
After installing such a messaging client, the XMPP server must be configured in the client. All you have to do is enter the corresponding TrutzMail address with password.
Since many XMPP clients determine the server name from the e-mail address, the incorrectly determined name "comidio.email" must still be changed to "trutzbox”.
The XMPP default port 5222 remains unchanged.
Several TrutzMail addresses can also be configured in one client.

Afterwards any number of contacts can be added by entering the TrutzMail addresses.

4.4.1.2 TrutzChat XMPP Standard Functions
Depending on the functionality of the messaging client, the XMPP server on the TrutzBox supports the following XMPP standard functions:
- Instant-Messaging: Text messages incl. formatting and emoticons
- Create and manage communication groups, group chats (multi-user chat - MUC ), but currently only for communication participants who are logged on to the same TrutzBox.
- Audio/Video Communication: Telephone Calls
- File transfer: Send files to the communication partner(s)
- Screen Sharing: makes one's own screen visible to others
- Remote-Desktop: the communication partner can operate my PC
- OTR (Off-the-Record Messaging): unofficial, confidential, non-public communications
- Online-Status, Last-Seen: is the communication partner online, ready to talk... or when was the last time he was online
-> Table of Contents (of this manual)
4.4.1.3 External connections to TrutzRTC
As long as the TrutzBox with the host name "trutzbox" is available, the messaging client can connect directly to the XMPP server on the TrutzBox.
However, this only works from the home network if the client is connected to the Internet router or the secure network of the TrutzBox (transparent mode).
To connect to the XMPP server on the TrutzBox while travelling, the TrutzBox " Fernzugriff " should be used.
To do this, set up the TrutzBox remote access as described in „Fernzugriff“ and authorise the TrutzRTC user for remote access under " Benutzer verwalten " on the TrutzBox.
If „Fernzugriff“is then set up and started on the mobile device, the messaging program can access the TrutzRTC server as in the home network.
There is no need to open additional ports on the Internet router at home.

4.4.1.4 Setting up and using chat rooms ===
The TrutzBox is also used by clubs, groups of friends, schools, industrial projects etc. to communicate with each other safely. Such closed user groups can not only hold video conferences and exchange secure e-mails with several users simultaneously, but also communicate together via one (or more) chat rooms. Such chat rooms are also called Multi User Chat (MUC).
<
To do this, it is possible to create a chat room on my own TrutzBox, i.e. the TrutzBox, where I have a TrutzMail address, and then invite any number of participants with their TrutzMail address.
<
For example, to create a new room in the chat program Adium, call the menu „Ablage“ -> „gehe zu Chat..“ auf:
The fields have the following meaning:
Konto: select here the TrutzMail account under which the "chat room" is to be createdl
Raumname: define a room name (here myroom) and append the user account (without @comidio.email) behind it in parentheses. The room name must not contain any special characters
Server: do not change anything
Handle: do not change anything
Passwort: an optional access password can be entered here
Kontakte einladen: here you can separate participants by commas and invite them to the room. Participants can also be invited or unloaded separately at a later date
Einladungstext: here you can enter any text that is displayed with the invitation.
Once the room has been created in this way, further contacts (in the contact list with the right mouse button - menu "Invite to chat") can be invited into the room.
<
The chat room is then located on the TrutzBox on which the room was created. Participants from another TrutzBox are automatically notified with the invitation and connect to this room.
4.4.2 TrutzMeeting: Audio- and Video-Conference Service
Using the XMPP server and the correct messaging client, it is possible to establish an audio/video connection, but only with one other participant, and it is necessary that all participants use a client that supports the same audio/video code. Therefore, standard XMPP clients are not an optimal solution for telephone or video conferences.
To provide TrutzBox users with a secure solution for multiparty telephone or video conferencing, the TrutzBox offers a WebRTC-enabled conference server that allows audio/video conferencing directly from a standard Internet browser, without the need for additional software.
Around the TrutzBox user also a secure solution for telephone or video WebRTC is a living standard defined in phases, which is gradually implemented by the browser manufacturers. This means that there are no uniform functionalities across all browsers and the WebRTC functions run differently stable.
For example, the screensharing function is not yet implemented stably.We will update with appropriate browsers.
4.4.2.1 preconditions
During the later operating phase, the maximum number of video conference participants will correspond to the TrutzMail addresses booked.
There is no participant limit in the current beta test phase.
To start a video conference, simply access the TrutzBox on port 9082 using a WebRTC-enabled browser.
A room name is appended to the end of the link:
z.B.: https://trutzbox:9082/raumname
No special characters may be used for the selected room name!
4.4.2.2 procedure
Durch Aufruf der oben genannten URL verbindet sich der Browser mit dem Raum “raumname”. Dabei sind zwei Fälle zu unterscheiden:
- The room does not yet exist:
so you are now the first person who wants to create this room, and you are the "room administrator" for this room. Then it is necessary to log on to the conference server with his TrutzMail address and the TrutzMail Password. This means that only TrutzBox users who have a TrutzMail account on this TrutzBox can open a new room. After creating and connecting to the room, the room administrator can optionally define another password for this room.
- The room already exists:
then the browser connects to the room. If the room administrator has placed a password in the room, this must now be entered. If the room has already been created, anyone can connect to the room. He does not need to be registered as a TrutzBox user or have a TrutzMail address. As soon as the browser is connected to the room, you should enter your "Anzeigenamen" by clicking on the connection window below.
Positioning the mouse at the top of the screen opens an operating menu.
This menu offers the following functions:
-> Table of Contents (of this manual)
4.4.2.3 Screen-Sharing
With the function "Share your own screen with the participants" it is possible to share your own screen content with other conference participants.
Since all browsers have a built-in security setting that prevents software from reading the screen content, the browser must be informed that the TrutzBox may read the screen content.
Chrome
With Chrome it is necessary that this feature is already activated when you call it up.
Chrome on Mac
For this purpose on the
- Mac: start chrome in the console with this command:
open -a 'Google Chrome' --args '--enable-usermedia-screen-capturing'

Firefox
For Firefox' you have to change an internal configuration after starting Firefox by entering the command about:config. Search for allowed and add the domain trutzbox to the list of allowed domains by double clicking on the parameter "media.getusermedia.screensharing.allowed_domains"'.
4.4.2.4 Performance limits of the conference server
The TrutzRTC conference server is based on the open source software Jitsi-Video-Bridge . Although this conference server is very powerful and the TrutzBox hardware is also very powerful, the number of participants is not unlimited. The number of participants depends on the speed of the Internet connection of each individual participant and the TrutzBox owner. Approx. 40KBit/s up- and down-load speed per subscriber is sufficient for voice transmission. For camera or screen sharing up to 800 KBit/s are required. Thus, with normal DSL/VDSL Internet connections, bottlenecks will probably occur before the TrutzBox hardware becomes a bottleneck. Such Internet bottlenecks can best be analyzed on the Internet router.
4.4.2.5 External connections to the TrutzRTC conference server
No TrutzBox is required to connect to the TrutzBox conference server externally, i.e. via the Internet. Who knows the link (and the possibly assigned password), can participate in the conference. This makes it easier to use webinars or spontaneous conferences.
To do this, however, these two ports must be opened on the Internet router and forwarded to the TrutzBox:
- TCP-9082
- UDP-9083
With the link "https://externe-ip-adresse:9082/raumname" the room can then be joined on the Internet.
Since the external IP address changes once a day for most home Internet connections, it is advisable to use a DynDNS service here as well.
Another way to determine the correct external link for participating in a conference has been integrated into the TrutzBox XMPP server. If you transmit the symbol "#" with a room name to a person in the XMPP chat, then this "command" is converted into the external link to the conference server. This means that:
#meinraum
converts into the address
https://188.107.13.86:9082/meinraum
which the chat participant can click directly.

4.5 TrutzBox® shutdown (do not unplug!)
If a TrutzBox is to be switched off and/or restarted, please DO NOT disconnect the plug, but proceed as follows:
4.5.1 TrutzBox® shutdown, "switch off" via TrutzBox user interface
In the TrutzBox user interface:
- Click on „System“ -> „Ein-/Ausschalten“
- if you want TrutzBox to start up again: Click on the button „Neu starten“
- if TrutzBox is to be switched off: Click on the button „Ausschalten“
4.5.2 TrutzBox® shutdown, "switch off" via Webmin
If the administrator can no longer access the TrutzBox user interface, an attempt is made to access it directly via Webmin. Call up in the browser: https://trutzbox:10000/ :
- Enter admin as user
- Enter the administrator password of the TrutzBox
- Click on „System“ -> „System-Start und -Stop“ and scroll all the way down
- if you want TrutzBox to start up again: Click on the button „System neu starten“
- if TrutzBox is to be switched off: Click on the button „System herunterfahren“
4.5.3 TrutzBox® shutdown, "switch off" Emergency
If the administrator
- neither via the user interface
- nor about Webmin
an access, in an emergency, the "connector must be disconnected".
Please wait approx. 10 seconds and then reconnect the power supply.
If the TrutzBox does not start up (correctly) in approx. 15 minutes, please contact Comidio Support : Email to support@comidio.de .

4.6 TrutzServices
4.6.1 TrutzServices in active subscription
The quality of protection provided by TrutzBox® depends largely on how up-to-date the software is with regard to functions and data. This is only guaranteed if the TrutzBox® receives regular and automatic updates.
TrutzServices, the Comidio services for TrutzBox®, include the following update services:
- TrutzBrowse: Updates for header extensions, slider presets and blacklists,
- TrutzMail: Updates of Receiver Certificates,
- TrutzContent: Updates for filter lists,
- TrutzBase: Signatures and updates for virus scanners and
- TrutzBox® Software: Fault-fixes, security updates and minor functional extensions.
All these services are included in TrutzServices.
The updates were carried out partly regularly (e.g. virus scanner updates), partly on an occasion basis (e.g. security updates). Major updates run in the early morning hours (around 04:00) so that they do not disturb the user.
Therefore it is not only useful to leave the TrutzBox® constantly switched on for the e-mail exchange, but also necessary for the execution of the updates.
4.6.2 What happens if TrutzBox services are not being extended?
In this case, the TrutzMail certificates expire, i.e. services that are bound to these TrutzMail addresses can no longer be used. Currently these are:
- the exchange of TrutzMails,
- TrutzRTC (Video Conferences and Chat),
- Comidio-Software-Updates.
The Debian updates can still be imported. All other services, such as TrutzBrowse and TrutzContent can still be used, but without updating the filter lists. The same would apply if Comidio did not renew its services.
Since the TrutzBox hardware is based on a high-quality standard board (an APU2 from PCEngines), the hardware could be used as a powerful server (including the built-in SSD disk) for other purposes.

5 Administrating the TrutzBox® (for TrutzBox® Administrator)
The TrutzBox® is delivered by Comidio with security settings suitable for everyday use, so that even inexperienced users can email and surf immediately protected and without a trace.
Setting up additional e-mail addresses and administration of the TrutzBox ® is performed by the administrator, i.e. the person who also performed the initial setup of the TrutzBox ® during setup.
The administrator can, but does not have to, adapt a variety of function parameters to his own requirements.
You can open the TrutzBox® User interface on any connected computer.
- Open an Internet browser.
- Enter "http://trutzbox" in the address bar.
The following input window appears.
When logging on, the administrator is prompted for the corresponding password (specified by the administrator during setup).
Enter the password and click on „Anmelden“.
After correct password entry the homepage of the TrutzBox® user interface with the title "TrutzBox® Übersicht " appears“.

5.2.4.1 Manage mail exchange (PGP)
With this functionality, TrutzBox owners can additionally exchange PGP-encrypted e-mails with non-trutzBox owners in addition to TrutzMail (automatic exchange of content and metadata of encrypted e-mails between TrutzBoxes).
- The first section describes the transmission options.
- The second section describes the reception options.
- The third section gives an overview of all transmission and reception options.
- The fourth section explains how the signature and encryption are displayed.
5.2.4.2 Sending and receiving options
The following graphic shows all transmission and reception options
- (Se1) Send on TrutzBox to TrutzBox (TrutzMail), encrypted meta and content data.
- (Se2) Send on TrutzBox to "PGP receiver", content data PGP-encrypted.
- (Em1) Received on TrutzBox from TrutzBox (TrutzMail), encrypted meta and content data.
- (Em2) Received on TrutzBox from "PGP transmitter", content data PGP-encrypted.
- (Em3) Received on TrutzBox from "open transmitter", all data unencrypted.
-> Table of Contents (of this manual)
5.2.4.3 send emails
If an email is to be sent' via the TrutzBox, the TrutzBox first checks whether the recipient is a TrutzBox …
- (Se1) if yes, email content and metadata are automatically encrypted by the TrutzBox and sent to the recipient TrutzBox via TrutzMail,
- if no (the recipient is not a TrutzBox and an external mail gateway has been configured in the (sender) TrutzBox), the TrutzBox checks whether it has a public key for the recipient's e-mail address...
- '(Se2) if yes, Email content is PGP-encrypted and sent to the recipient's public mail server via the sender's external mail gateway,
- if no (the TrutzBox has no public key of the recipient), the e-mail is not sent and the TrutzBox returns an error message to the mail program.
| Emails are not sent open (unencrypted) by the TrutzBox: either fully encrypted to TrutzBox owner (Se1) or Content encrypted to "PGP recipient" (Se2). |
If the recipient list contains mixtures of e-mail addresses with TrutzBox and public e-mail addresses, the e-mail is only sent if the TrutzBox knows the public keys for all public e-mail addresses.
Otherwise there is an error message and the e-mail is not sent.
<
Preconditions for sending from the TrutzBox to a "PGP receiver" (Se2)
1. Set up your own external mail gateway on the TrutzBox
To be able to address normal standard mail accounts from the TrutzBox, an external mail gateway must first be set up on the TrutzBox. This mail gateway can be a normal SMTP server of a standard mail account with a public mail provider. Thus it is possible for the TrutzBox administrator to enter the e-mail account of his own public e-mail provider here.
Under the menu item "Manage users" you can enter an external mail gateway for each TrutzBox user (e.g. his t-online mail account):
-> Table of Contents (of this manual)
2. Importing the public key
To exchange PGP-encrypted e-mails with someone who does not have a TrutzBox, the TrutzBox must know the public key of the recipient. To do this, this public key of the TrutzBox must first be made known on the TrutzBox under "TrutzMail" ->"Key management" Button "Add key:
-> Table of Contents (of this manual)
Here, the public key can be
- uploaded from a file or
- copied into the input field with " Copy " and " Paste ".
Then click on the "Add" button to start the upload.
-> Table of Contents (of this manual)
If the TrutzBox knows a public key for a mail recipient whose mail address does not end with @comidio.email, this e-mail is encrypted with it.
5.2.4.3.1 Receive e-mails
If an e-mail is to be received' via the TrutzBox (i.e. the target address ends with @comidio.email), there are three differentiations:
- span style="color: green">'(Em1)' sent by a TrutzBox: fully encrypted (incl. metadata) directly to the receiver TrutzBox (see first case above Se1)
- sent by a normal e-mail server (i.e. sender does not have a TrutzBox), this e-mail is always received via the central Comdio e-mail gateway and forwarded to the recipient TrutzBox:
- (Em2)' E-mail was encrypted by the sender with the public key of the recipient @comidio.email: then the TrutzBox decrypts this e-mail automatically.
- '(Em3)' E-mail was encrypted by sender not: then the TrutzBox receives this unencrypted e-mail .
| This means that the TrutzBox can receive TrutzMails (Em1), PGP-encrypted e-mails (Em2) and unencrypted e-mails (Em3). |
Preconditions for receiving PGP-encrypted e-mails from "Non-TrutzBox owners“(Em2)
Export and, if necessary, email your own public key to the potential "PGP sender "
You can give a "Non-TrutzBox owner" the possibility to send you an encrypted e-mail to the TrutzBox. To do this, give them your public key. The public key of each TrutzMail address can be downloaded here (TrutzBox user interface: "Manage User" click on the corresponding TrutzBox user) and sent to another mail sender:
Since the public key does not require any secrecy, it can be sent "openly" by e-mail.
-> Table of Contents (of this manual)
5.2.4.4 Identification of e-mails in the subject line ==
'"Send e-mails
All e-mails sent via the TrutzBox are automatically encrypted by the TrutzBox. If the recipient is a TrutzBox (and thus the mail address ends with @comidio.email), then the TrutzBox automatically obtains the required public key of the recipient. If the recipient does not have a TrutzBox (and therefore a normal e-mail address has been addressed), the TrutzBox administrator must first inform the TrutzBox of the public key of the recipient. For security reasons, it is not possible to send an e-mail to a recipient if the recipient's public key is unknown.
Receiving emails
All encrypted e-mails received by the TrutzBox are automatically decrypted by the TrutzBox and made available for retrieval of an e-mail program. The TrutzBox can also receive e-mails from normal e-mail servers. These can be either encrypted or unencrypted. To show the recipient of the e-mail whether the e-mail was encrypted or unencrypted and whether the TrutzBox was able to check the sender's signature, the TrutzBox adjusts the mail subject field in the e-mail.
The TrutzBox places text in square brackets before the mail subject as first the letter
- U - for unsigned (the TrutzBox could not confirm the sender), or
- S - for signed (the TrutzBox was able to confirm the sender)
and as second letter
- U - for unencrypted (the mail content was readable on the way), or
- E - for encrypted (the mail content was not readable on the way).
Examples:
An unencrypted e-mail sent to TrutzBox from a normal mail account has not been encrypted and shows [UU] in the subject line (unsigned, unencrypted).
An encrypted TrutzMail sent by a TrutzBox to a TrutzBox has been encrypted and shows [SE] in the subject line (signed, encrypted).
An encrypted email sent to TrutzBox from a normal mail account has been encrypted and shows [UE] in the subject line (unsigned, encrypted).

5.3 TrutzBox® Filter
TrutzBox® Filter functions are called, e.g. by clicking on the menu item TrutzBox® Filter in the navigation menu on the left side of the "TrutzBox® Overview" page, and then selecting one of the submenu items
- Status,
- User Configuration,
- User groups,
- Filter lists,
- TrutzBrowse.
5.3.1 Status
The TrutzBox offers the administrator extensive functions for controlling the Internet communication of browsers and other apps. The menu item TrutzBox Filter -> Status lists the communication for the device currently in use. The communication of the other devices can also be called up here via further tabs.
Clicking the blue function menu 
next to the time activates a menu to change the security slider level of this link. This is especially useful for non-browser apps that cannot display a security slider.
The colored digits show the slider position set for this call, thus the security level.
The icons to the left of the slider position 
(1) , 
(2) , 
und 
(3) are showing the TrutzBox status:
| (1) |
white exclamation point on red square |
Trackers were found and stopped in this call. |
| (2) |
black exclamation point on yellow triangle |
The TrutzBox was bypassed with this call. After clicking on the link to the right of the icon: "SecSlider at position 10, no https filtering performed". |
| |
half entry- prohibition- character |
TrutzContent was used, i.e. a page should be called which was blocked by TrutzContent. |
| (3) |
white exclamation point< on red triangle |
The TrutzBox has detected an internal problem when analyzing the connection to the client (end device) or to a server. Click on the link to the right of the icon to see why the connection was not established. |
Here are two exemplary causes for :
Fall 3a - „CONNECT“: the following or similar explanation is displayed "CONNECT request without any subsequent Requests. This might indicate that the client application refused to connect through proxy“. Such an error message is caused by an http-Connect command. With an http-Connect command, a client wants to tunnel past the TrutzBox to connect to the server.(https://en.wikipedia.org/wiki/HTTP_tunnel#HTTP_CONNECT_tunneling). However, since no further http requests follow for this server, this message is generated. Usually the client just wanted to check if there is a proxy (in this case the TrutzBox) between it and the server.
Fall 3b - „ERROR": the following or similar explanation is displayed: "Error: 3074291456:error:14094418:SSL routines:ssl3_read_bytes:tlsv1 alert unknown ca:../deps/openssl/openssl/ssl/s3_pkt.c:1472:SSL alert number 48 3074291456:error:140940E5:SSL routines:ssl3_read_bytes:ssl handshake failure:../deps/openssl/openssl/ssl/s3_pkt.c:1210:“ Such an error message is generated if the TrutzBox has an internal connection problem (in this case a problem in the SSL library).
Further cases may occur.
Usually such an error message is generated by a client application (app) and not by a browser. Such an error message may affect the correct functioning of the client application. If you want to allow the application to contact this server, please set this server to L10 by clicking the blue function menu , there under "Change slider setting".
-> Table of Contents (of this manual)
5.3.2 Filter configuration
Here you configure devices, manage user rights and set up the security slider.
If necessary, the root certificate (for browser or e-mail use) is downloaded to the physically used device (here: Elitebook) by clicking on "Download root certificate".
If you check the box "If SSL errors occur, automatically disable filtering for your domain", a slider will be automatically set to L10 (bypassing the proxy) for applications that want to establish an encrypted connection to their server. If you do not check the box and an app (likation) cannot establish a connection, you can set the security slider to L10 under TrutzBox Filter/Status for the relevant connections for this special case.
In this view, the active device (here: Elitebook) is automatically opened and user groups and exceptions can be assigned to it. The use of the Tor network is also switched on or off here for the activated device (highlighted in blue). The pseudonymization of the IP address can be activated via the "Use Tor network" menu item. However, it should be noted that some web servers can cause additional problems when using Tor.
To configure further displayed devices, please click on the respective device (name or IP address) and proceed as described above.
If the "Block unknown users" button is not checked, the settings for the device apply and a user logon is not required.
If the "Block unknown users" button is checked, the settings apply to the individual user and he must log on to this device with his TrutzMail address and the corresponding password (see Managing Accounts/Users).
-> Table of Contents (of this manual)
The administrator is able to block browser access to certain web content for connected devices or individual users, which was previously adopted or defined as a blacklist (what should be prohibited) or whitelist (what should be allowed as an exception) under "Configure user groups". This allows parents to block unsuitable content for children or young people. It is also possible to restrict access to predefined web addresses (domains or URLs) for smart devices that do not have an Internet browser (household appliances, watches, fitness wristbands...).
Special access rights can also be set for "Smart Home" devices. The "Use Tor network" menu item can be used to activate IP address pseudonymization by using the Tor network with TrutzBrowse.
However, it should be noted that some web servers can cause additional problems when using Tor.
-> Table of Contents (of this manual)
The user group relevant to the individual user is assigned here.
-> Table of Contents (of this manual)
Default values of the Security Slider are set here, which the administrator can adjust as required.
Host names that cannot be called via the browser (e.g. TV set) can also be managed here.
Comidio delivers standard slider positions for some frequently used web servers, which are marked with the symbol (white "i" on black circle area) [Who: "default"]. These cannot be deleted, but the TrutzBox administrator can adapt the security level specified by Comidio to his needs. With "Add" you can enter your own slider positions for hosts and delete them with "X" again [Who: "admin add"].
By entering an "*" in the host name, all URLs ending with the name to the right of the "*" can be addressed. If the proxy finds a URL that is entered several times in this list, the security level of the longest entry is used.
If the option "If SSL errors occur, automatically disable filtering for selected domain" is activated in the "Configure Filter" menu, the TrutzBox Proxy automatically enters an activation of servers that a client application wanted to build encrypted to this server[Who: "auto"].
There are thus four possibilities, how a Security-Slider entry gets into this central database. All users and devices use this database:
- Default setting of Comidio, these can be changed by the user, but not completely deleted[Who: "default" or "admin change"].
- A slider setting of a user by the security slider in the browser has taken place[Who: "slider"].
- New entry here in this mask. Here also unqualified entries "*.domain.com" can be made, but only on the left side of the domain name[Who: "admin add"].
- The TrutzBox detects an SSL error and the flag "If SSL errors occur, automatically disable filtering for the selected domain" is activated. However, this entry only takes place if there is no entry by the user. So no entry of case 2 or case 3[Who: "auto"].
-> Table of Contents (of this manual)
5.3.3 Configure user groups
The administrator is able to block browser access to specific web content for connected devices or individual users. This allows parents to block unsuitable content for children or young people. It is also possible to restrict access to predefined web addresses (domains or URLs) for smart devices that do not have an Internet browser (household appliances, watches, fitness wristbands...).
In the "User Configuration" menu, existing user groups are managed, new ones are created and filter lists are assigned to the user groups.

5.3.4 Filter lists
Under the menu item TrutzBox® Filter lists -> Manage Trutz filters, the TrutzBox® Administrator can manage filter lists containing Internet domains or Internet URLs. Comidio delivers approx. 110 filter lists containing 55 different Internet topics. These filter lists are maintained by Comidio and the updates are transferred to the TrutzBoxes at short intervals. With this menu item, the administrator is able to view these standard lists delivered by Comidio, to search them and to create his own new blacklists and whitelists.
The filter lists managed by the TrutzBox® are used by TrutzBrowse (pseudonymization and tracker blocking) as well as by TrutzContent (protection against unsuitable websites):
In this TrutzBox® menu new Black- and Whitelists can be created (click on "New Filters"), which can then be used with TrutzBrowse as well as with TrutzContent. For this purpose, however, a newly created black or white list must first be activated under TrutzContent or TrutzBrowse. With an automatic system update by Comidio, only standard TrutzBox blacklists and whitelists are adapted. The lists created and managed by the administrator are not changed by this..
-> Table of Contents (of this manual)
5.3.5 TrutzBrowse
With TrutzBox®, the TrutzBox® administrator can individually configure each Internet-enabled device or a single Internet user. Furthermore, under the TrutzBox® Filter menu (TrutzBox Filter/Filter configuration) you can also adjust the security slider setting for each position.
All settings affect all devices and users of the TrutzBox®. It is not possible to configure TrutzBrowse settings differently for each user or device. It is only possible to vary the TrutzBrowse filters for a website by adjusting the security slider as desired. This setting for a web page is saved and affects all TrutzBox users..
For each position of the Security Slider, the "+" symbol, the description of the slider position, the HTTP requests and HTTP response headers, cookies and domain blocker lists can be adjusted by "expanding":
-> Table of Contents (of this manual)
After many tests, Comidio has defined a default setting, which can, however, be changed flexibly by the administrator of the TrutzBox® to meet his security requirements.
In this default setting, the following 10 security levels apply:
- L1: All filters active
- L2: Fixed "Accept-Language" value
- L3: "From" value allowed
- L4: Unknown headers allowed
- L5: 'Accept-Language' value allowed
- L6: 'User-Agent' value allowed
- L7: Data tracker allowed
- L8: Third-party cookies allowed
- L9: Reserved for future expansions
- L10: no filters active
With the slider position L10 the TrutzBox® Proxy is completely bypassed. The TrutzBox protection function is switched off. This slide creation makes sense e.g. for apps on Android or OSX, since they usually check against their own certificate. If the slider is set to L10 and the web page is reloaded, no TrutzBox® slider icon is displayed because the proxy is no longer active..
If required, the corresponding criteria can be individually adapted in four categories by clicking on "+".
-> Table of Contents (of this manual)
In the menu item "TrutzBox Filter -> TrutzBrowse / Configure Filter" the administrator can adapt the security slider description for each level.
-> Table of Contents (of this manual)
This default setting determines which HTTP request header data is forwarded or blocked.
-> Table of Contents (of this manual)
This default setting determines which HTTP response header data is forwarded or blocked.
-> Table of Contents (of this manual)
Advanced settings can be made here for each security slider position.
The default header filters are based on extensive Comidio tests. Depending on the position of the security slider, these filter values are a compromise between the least possible restriction of the functionality of typical websites on the one hand and the protection of privacy on the other.
-> Table of Contents (of this manual)
Under "Filter lists used" the filter lists are activated which should be active when browsing through the TrutzBox® (TrutzBrowse). By default, no filter lists for advertising companies are activated; i.e. TrutzBrowse does not filter out advertisements in the displayed web pages. The TrutzBox® Administrator can activate this at this point by activating "adv_domain" and "adv_url" with a tick.
-> Table of Contents (of this manual)
5.3.5.1 Statistics
The two lists show the top 100 most used (and thus blocked!) trackers and the top 100 websites with the highest (and thus blocked!) number of trackers since the last reset. By pressing "Reset" the statistic is set to 0 and starts again.
By clicking on a blue arrow in the 1st list, the websites on which this tracker is represented or blocked by the TrutzBox are listed.
Clicking a blue arrow in the 2nd list lists the trackers set on these web pages or blocked by the TrutzBox.
-> Table of Contents (of this manual)
5.4 TrutzMail
TrutzMail functions are called up, for example, by clicking on the menu item TrutzMail in the navigation menu on the left-hand side of the "TrutzBox® Overview" page, and then selecting one of the three submenu items
- Status,
- Logs,
- Webmail.
-> Table of Contents (of this manual)
5.4.1 Status
Here you can see the TrutzMail status.
This page is only required if the mail client displays an error message or if e-mails cannot be received or cannot be sent.
An e-mail can "get stuck", i.e. it cannot be sent if, for example, there is no Internet connection, a process is not running or there is a problem with certificates.
The "Renew mail key" button is located at the top right. Click on this if a communication partner has deleted an e-mail address on his TrutzBox and created it again under the same name. In this case, "my" TrutzBox® has an outdated certificate. Click on "Renew mail key" to delete all saved certificates. With the next communication request from another TrutzBox® the corresponding certificates on "my" TrutzBox® are automatically renewed by the Comidio server and the communication partners can exchange e-mails as usual. You can press this button at any time; the functionality of the TrutzBox ® is not affected.
In the upper area the states of 2 processes are described, which can also be restarted here:
- "SMTP": green indicates that sending e-mails from the mail client (e.g. Outlook) and mail server TrutzMail works, and
- "IMAP": green indicates that receiving e-mails from the TrutzMail mail server to the mail client (e.g. Outlook) works.
In the case of a red display, the circle arrow symbol for "Restart service" must be pressed.
Below this a possibly existing queue (mail queue) with individual e-mails and their statuses is displayed..
For each displayed e-mail 3 buttons can be used:
- "Send now": this e-mail is sent again;
- "Display": shows parameters and content of the e-mail in detail:
-> Table of Contents (of this manual)
- "Delete mail": offers the possibility to remove this e-mail from the queue:
TrutzMail Status indicates whether, and if so, which secure e-mails have not yet been sent; click "Send now" if necessary or ask the addressee whether he has his TrutzBox® in operation.
-> Table of Contents (of this manual)
5.4.2 Logs
If necessary, Comidio Support will ask you to download Mail log to your PC by clicking on "Download" and then email the files to support@comidio.de.

<br/>
Here the TrutzBox can be reset to factory settings.
<br/><<br/>
Since the factory reset deletes all settings and e-mails on the TrutzBox, it is advisable to save the data before starting the factory reset:
*Emails by transfer into an e-mail client software (e.g. Outlook, Thunderbird, Apple-Mail)
*Settings (see previous chapter 5.6.1.2 Creating a backup copy):
**Save to backup file before factory reset and
**Restore after factory reset from backup file.
<br/>
'''ATTENTION: the following steps 1 & 2 must be carried out BEFORE restarting (8.)!'''<br/>
The reset is done chronologically as follows:
#Delete any certificate already downloaded with the name "trutzbox.cer" in the "Downloads" folder.
#Delete any certificate already imported with the name "TrutzBox" in the browser.
#'''Click on "Reset to factory default"'''' <br/>Data will be deleted and restarted; please wait until the 3 LEDs on the front of the TrutzBox<sup>®</sup> have all gone out (this can take up to 1 hour).
#Remove power supply (DC 12V) from TrutzBox<sup>®</sup> (back side).
#Check that TrutzBox<sup>®</sup> is connected to the Internet Router (e.g. FRITZ!Box) via network cable.
#Check that the USB Wireless LAN adapter is connected to TrutzBox<sup>®</sup> via USB cable.
#Wait approx. 1 minute (without power).
#Reconnect power supply (DC 12V) to TrutzBox<sup>®</sup> (back side).

===== Log proxy activities with debug =====
There may still be network accesses that are not displayed in status. We are currently working on a new version of the proxy, which also improves this point.
The only way to really analyze all activities of the proxy at the moment is the TrutzBox debugger. You can activate this by setting the position proxy to Debug under "System" -> "Debug". The proxy then logs all activities in its log file. You can download it from the same menu or watch it in real time with "Open Log Window" (possibly activate the log files of interest in the Log.io window, e.g. "node_proxy").
After the test, please set the "proxy" position to "Information" again to prevent a memory overflow. If you want to evaluate the log file, we recommend deleting the log files with "Delete all log files" before the test..

Situations may occur in which shutting down and then restarting the TrutzBox<sup>®</sup> makes sense.
In such a case, it may take a few minutes for connected devices, e.g. PCs, to resolve the name "trutzbox".
So it may take a few minutes until access to <nowiki>"http://trutzbox" works.
The same delay may occur if a PC (Microsoft or Apple) connected to the TrutzBox® is rebooted instead of the TrutzBox®..

Structure and use of certificate management systems
<
First, the TrutzBox certificate (trutzbox.cer) is downloaded from the TrutzBox to the PC intended for use. Unless set otherwise by the user, the download takes place in the "Download" directory of the PC.
In principle there are 2 certificate management systems'' on one PC, one in the operating system, here Windows 10 for example, and - if Firefox is used - a second one of Firefox.
| A Import certificate (trutzbox.cer) into certificate management system |
| In the Firefox certificate management system, the TrutzBox certificate is imported via the Firefox browser. | In the operating system certificate management system, the TrutzBox certificate one-time' is imported directly from the operating system or via any other browser, except the Firefox browser. |
-> Table of Contents (of this manual)
| B. Use of the certificate (from all browsers) |
| When using the Firefox browser, it accesses the TrutzBox certificate in its own certificate management during operation. | All other browsers access the TrutzBox certificate in the operating system certificate management system during operation. |
-> Table of Contents (of this manual)
| C. Opening or deleting the TrutzBox certificate |
| Accessing or deleting the TrutzBox certificate in Firefox certificate management systems is done via Firefox browser. | The TrutzBox certificate can be opened or deleted in the operating system certificate management systems once only' via the operating system or any other browser, except the Firefox browser. |

6.2 Connect device with TrutzBox®
Assumption: the TrutzBox® was connected to the Internet router via network cable (red connection in the following figure).
There are basically two ways to connect devices to the TrutzBox®:
- PC 1 is connected to the Internet router via WLAN or network cable (dashed yellow).
- PC 2 is connected to the TrutzBox® via WLAN or network cable (green dashed).
| case 1: | In order for Internet traffic (surfing) via the TrutzBox®, the TrutzBox® must be entered as proxy (= deputy, quasi "doorman") in the respective browser of the PC.The entry must be made separately for each browser. This mode is called "Proxy mode". |
| case 2: | All Internet traffic (surfing) automatically passes through the TrutzBox®.This mode is called "Transparent mode". |
In both cases, TrutzBox® controls both incoming and outgoing Internet communication.
The aim is to connect as many or all devices as possible in the home network directly via the TrutzBox® (i.e. in "transparent mode").
It is advisable to reach this state step by step.
Therefore you should start "small" at the beginning and gain experience in "proxy mode".
You can also surf in a browser (e.g. Firefox) in proxy mode while surfing in a second browser (e.g. Chrome) without protection. For example, you can track the influence the security slider has on unprotected access in various positions (e.g. effects on advertising offers shown).
Once you have gained sufficient experience in proxy mode, you can gradually connect devices in transparent mode by connecting the devices directly to the TrutzBox® via WLAN (or network cable).
To change from transparent mode to proxy mode or vice versa, proceed as follows:
- Shut down PC or device
- If previously connected to TrutzBox, now connect to the Internet router or vice versa
- Switch on/restart the device (now the device automatically receives an IP address valid in this network area)
-> Table of Contents (of this manual)
6.2.1 Set up TrutzBox® as proxy (proxy mode) in...
Comidio offers a so-called "proxy configuration URL" so that the user does not have to make name and port settings every time.
This is: "http://trutzbox/api/proxy/pac"
The following sections describe how to configure the proxy configuration URL in your browser. Once entered, the browser "remembers" it and the browser then accesses the Internet in a controlled manner through the TrutzBox. You can later simply switch on and off the TrutzBox by clicking on
"No proxy" and
Automatic proxy configuration URL" or "Use script for automatic configuration"<.br>

When selecting wireless network connections, click (2.) on your TrutzBox® SSID (WLAN name assigned under 4.6 when setting up). Then click on "Connect" (3.) and enter the WLAN password in the window that appears (4.). By clicking on "OK" (5.) the confirmation (6.) appears.
From now on you use TrutzBrowse, TrutzContent and TrutzBase.
6.3 TrutzBox®-network
To ensure maximum security for the devices connected to the TrutzBox®, the TrutzBox® sets up its own network separate from the Internet router. A DHCP server gives the connected devices a new IP address from the range 192.168.195.50 to 192.168.195.199. A separate DNS server (dnsmask) forwards the name resolution for the connected devices to the DNS server of the Internet router.
The TrutzBox® takes over the routing between the TrutzBox® internal network (WLAN, LAN-Int1 and LAN-Int2) and the TrutzBox® external network (Lan connection "LAN-Ext").
The TrutzBox® itself has the IP address 192.168.195.200 in the internal network. The IP address of the TrutzBox® is obtained from the Internet router when it is started.
A permanently assigned (static) IP address from the range 192.168.195.50 to 192.168.195.199. can also be assigned to a connected device. Subnet mask is then 255.255.255.0, the router and DNS server IP address is 192.168.195.200.
-> Table of Contents (of this manual)
6.3.1 Firewall
A Statefull-Inspection Firewall has been installed to provide additional protection for both the TrutzBox® and the internal network connected to it. This not only protects the TrutzBox® itself from unauthorised access to the network side, but also blocks external attackers. In addition, the firewall protects all connected network devices against uncontrolled network access via appropriate port shares.
<
The firewall used is a Stateful Packet Inspection Firewall (SPI), i.e. each data packet is assigned to a specific active connection (session):
- All devices connected to the internal network are bridged so that they can communicate with each other without restriction.
- All connected devices can establish connections to "extern" (LAN-Ext) on all ports. If a device on the internal network wants to access a device on the Internet router (external network), then a fully qualified host name must be used (e.g..fritz.box must be appended). All connections via port 80/443 are automatically routed via the TrutzBox® Proxy (filter), which then controls incoming and outgoing data.
- An external connection to the TrutzBox® is only enabled for special ports
- Establishing a connection from the external network to the internal network is not enabled and is therefore not permitted.
The TrutzBox® Administrator can open additional ports as required.
<
The firewall is based on the open source firewall "iptables". In addition, the Shorewall Firewall package is provided as an add-on to provide experts with additional functions such as simplified user guidance or zone setup.

8 Application example
8.1 Limiting TV tracking
The number of companies interested in data is increasing rapidly. Even with a television, you can no longer be sure that no personal data is transmitted to TV stations or even manufacturers. Even in its terms of use, the TV manufacturer Samsung recommends not to say anything private in the presence of a smart TV, because speech recognition could transmit this anywhere (https://netzpolitik.org/2015/samsung-warnt-bitte-achten-sie-darauf-nichts-privates-vor-unseren-smarttvs-zu-erzaehlen/).
But not only the microphone or even the camera on the TV could spy on the user. Current generations of television are getting closer and closer to the technology of smart phones by extending the functionality of the television by downloading apps. And there is interactive TV (HbbTV). This enables app providers, TV set manufacturers, HbbTV providers, providers of electronic program guides (Electronic Program Giude - EPG) and TV stations to track user behavior (https://netzpolitik.org/2015/studie-anonyme-nutzung-von-smart-tvs-kaum-moeglich/ und https://www.lda.bayern.de/lda/datenschutzaufsicht/lda_daten/150227%20PM%20Datenschutz%20und%20Smart-TV.pdf).
So the question arises: how can you limit the tracking of the TV with the TrutzBox?
Here a short manual ...
First you have to make sure that the TV set only communicates to the Internet via the TrutzBox. The easiest way to do this is to connect the TV set to the TrutzBox via LAN cable or WLAN. After that, all standard TrutzBox filters for HTTP and HTTPS (i.e. ports 80 and 443) will automatically take effect.
Here at the example of a television of the type "Sony Bravia"
After switching on the TV set, TrutzBrowse shows that the TV is loading some data from sony.net and encrypted JS programs, pictures and other data from playstation.net.
In the further process, when one clicks through the menus of the television the Internet video offers, further profile data are transferred to playstation.net:
If you then call up the news on the TV via the Internet, it not only downloads data from Tagesschau.de, but also images from secure.footprint.net. Thus the American service provider Markmonitor (https://www.markmonitor.com) also gets the information that someone here retrieves data:
All this information exchanged via http/https (port 80/443) is already controlled by the TrutzBox. The TrutzBox function TrutzBrowse used the default profile to manipulate the http header data. With the menu item TrutzContent you can now also block individual URLs (domains) to which you do not want to supply data. E.g. "secure.footprint.net".
However, the TV can also exchange data via protocols and ports other than http. These ports/protocols can be controlled and blocked with TrutzBase.
9 What to do if... ?
9.1 ... WLAN is not working?
If the TrutzBox WLAN is not visible, i.e. does not show an SSID (WLAN ID defined by the administrator during setup) and the WLAN button in the TrutzBox user interface in the "TrutzBox Übersicht" is gray instead of green, proceed as follows:
- In the TrutzBox user interface go to "Netzwerk" -> "WLAN", scroll down completely and click on the "Apply" button at the bottom.
Wait a moment and check whether the SSID is visible. If not visible, restart the TrutzBox:
- In the TrutzBox user interface, click on "System" -> "Ein-/Ausschalten" and wait until the TrutzBox has shut down and started up again automatically.
Rebooting takes about 15 minutes. Then check whether the SSID is visible. If not visible, a factory reset may have to be performed.
- In this case, please contact Comidio Support so that they can accompany the factory reset by telephone if necessary.
9.2 ... a SmartPhone/Tablet app does not work?
Sometimes it is difficult to find out which servers an app wants to access. These must be identified in order to be able to assign SecurityLevel 9 or even 10 to their addresses, if necessary.
- Start and stop the app concerned because some SSL connections are enabled for the app the first time the app is started on the TrutzBox.
- In the TrutzBox user interface under "TrutzBox Filter" -> "Status" in the tab of the relevant device, delete the status: "Delete history". This prevents other accesses from covering the searched accesses.
- Then restart the app on the smartphone/tablet.
If the app does not yet work, under Status press "Neu laden" again to see which accesses are not on L10. If necessary, set this to L10.
Sometimes an app wants to access several sub-domains of xyz.com. In this case it may help if all sub-domains are activated by entering "*.xyz.com.
9.3 ... the browser and/or mail program reports a problem with the certificate?
That's normal. Import the TrutzBox® certificate into the browser and the mail program. Download the TrutzBox® certificate from the TrutzBox user interface (https://trutzbox/#mail/status).
9.4 ... the TrutzBurg (symbol of the TrutzBox in the upper right corner of the browser window) is not displayed
Browser Update?
Please check first if your browser is up to date; if not, update it.
NoScript" off?
The TrutzBurg (top right) is "injected" into the website by software. This only works if Java-Script is activated in the browser.
Therefore, the Java script should NOT be deactivated in the browser: the button should be set at: "Skripte allgemein erlauben", or the extension (add-on) "NoScript" should not be loaded or not activated.
Pop-ups allowed?
Please make sure that pop-ups are allowed.
If the TrutzBurg is still not displayed, please proceed according to the following flowchart or table:
-> Table of Contents (of this manual)
If the device is or should be connected to the Internet Router (proxy mode), continue with 3.
dd>Proxy Activation Detection
- Is the TrutzBox "pac file" entered and activated in the browser?
(see manual 6.2.1)
- Is the corresponding software switch set up and switched on?
This may be necessary for certain applications (e.g. smartphone apps), so that the app works as desired (but unprotected).
Level 10 can be set:
- by user: Call the SecuritySlider of the corresponding page and click on the green button "TrutzBrowse".
- by administrator: set the level to 10 in "Status" or in "Slider Einstellungen”
- automatic: if under "TrutzBox Filter" -> "Geräte" the check mark " Falls SSL-Fehler auftreten, Filtering für angesteuerte Domain automatisch ausschalten " is set
Joint work reset may be necessary.
| 1. Check if TrutzBrowse works correctly | Opening in TrutzBox User Interface: TrutzBox Filter -> Status If the call xyz.de is displayed for the device used? |
No, so call did not go via TrutzBrowse; continue with 2. Yes, with level 1-9; continue with 4. |
| 2. Does the current device access in "Transparentmodus" or in "Proxymodus"? | Determination of operating mode
Device is directly connected to TrutzBox via (W)LAN
The device is connected to the Internet Router and the TrutzBox is entered in the browser as a proxy (= quasi detour). |
|
| 3. is TrutzBox activated as a proxy in the browser? | If TrutzBox is activated as a proxy in the browser, continue with 6. If TrutzBox is not activated as a proxy in the browser, this is recommended (see manual 6.2.1), and then page xyz.de should be called again. |
|
| 4. Displayed in "Status" with level 1-9 Intention: |
In Status: Click on link call (xyz.de) right of security level |
In a few exceptions the display of the TrutzBox symbol with sign and number of trackers cannot be shown on the respective website. Nevertheless, protection exists and the results (calls and tracker display and blocking) are correct. |
| 5. Displayed in "Status" with level 10 Intention a: |
Case b: in Status: Click on blue icon left of security level of xyz.de' |
|
| 6. xyz.de is not displayed in "Status" Restarting the TrutzBox |
restart via:
"System" ->"Ein-/Ausschalten"
Only if user interface is not accessible:
|
The "proxy part" of the TrutzBox does not seem to work or does not work properly. First restart or, in an emergency, perform a cold start. |
| 7. xyz.de is not displayed in "Status" Comidio asks you to send us the files "logs.zip". |
"System" ->"Debug": Click on "Alle Logdateien herunterladen". Save the file "logs.zip" (if necessary, the individual files). Mail the file "logs.zip" (if necessary the individual files) to support@comidio.de |
Comidio is interested in analyzing the error using the log files and therefore asks for the log files to be sent. Continue with 8. |
| 8. xyz.de is not displayed in "Status" Restart possible or contact Comidio Support |
Restart via: "System" -> "Ein-/Ausschalten" Click on "Neu starten". |

9.5 ... the e-mail gets stuck in the TrutzMail outbox?
Go to TrutzMail -> Status (https://trutzbox/#mail/status). Check whether TrutzMail, SMTP, IMAP each have a green check mark = are OK. If not, restart and press the round arrows to the right. Attention: this restart may take some time. The mail can therefore remain in the mail queue for some time. If it has not been delivered after some time, make sure that the TrutzBox® of the receiver is active, port 5888 (on the DSL router e.g. FRITZ!Box) is not open or the receiver has received a new certificate due to a factory reset, replacement of the TrutzBox®, etc. In this case go to TrutzBox® Overview -> TrutzMail -> Status and click on "Mail-Schlüssel erneuern" in the upper right corner.
9.6 ... the user interface (UI) is no longer accessible?
Make sure that the TrutzBox® is listed under Devices and Users on the DSL router (e.g. FRITZ!Box) in the home network. Otherwise you can also reboot your Internet-enabled device (e.g. PC), the DSL router (e.g. FRITZ!Box) and the TrutzBox®. If the TrutzBox® cannot be reached via the IP address, try the "traditional" method = remove the plug, wait a few minutes, reconnect the plug and restart the TrutzBox®.
It may take 5 - 10 minutes for it to start up.
-> Table of Contents (of this manual)
9.7 ... the right and middle LEDs are off and the left LED is constantly on?
Probably you cannot access Webmin https://trutzbox:10000 any more; then try the "traditional" method = remove the plug, wait a few minutes, plug in the plug again and restart the TrutzBox®.
It may take 5 - 10 minutes for it to start up.
Should the startup not bring the desired success, please contact us by e-mail at support@comidio.de.
-> Table of Contents (of this manual)
9.8 ... Your TrutzBox is not connected to the router or your terminal device (e.g. PC) cannot reach the TrutzBox?
The TrutzBox works exclusively with IPv4 addresses. If your TrutzBox is not connected to the router or your terminal device (e.g. PC) cannot reach the TrutzBox, one reason for this may be that the router assigns IPv6 addresses. To avoid this, it should be ensured that the router assigns IPv4 addresses. To disable IPv6 addresses, go to: https://comidio.de/wiki/index.php?title=TrutzBox_Handbuch#IPv6_deaktivieren
-> Table of Contents (of this manual)
9.9 ... Your router has had an "Internet failure" and your TrutzBox is no longer accessible after service has started (e.g. only the left LED is permanently light)?
Exceptionally, please try the "brutal" method = remove the plug, wait a few minutes, reconnect the plug and reboot the TrutzBox®.
It may take 5 - 10 minutes for it to start up.
Should the startup not bring the desired success, please contact us by e-mail at support@comidio.de.

9.11 ... if someone wants to sell his Trutzbox?
A TrutzLegitimation (consisting of TrutzKennung and TrutzSchlüssel) is person-oriented and not bound by concept to a specific TrutzBox. For example, the TrutzMail addresses configured are also linked to the TrutzLegitimation.
Thus the seller should not pass on his TrutzLegitimation and the buyer should order a new TrutzLegitimation including TrutzServices from Comidio.
We recommend the following procedure to the seller
The seller ...
- initiates factory reset on Trutzbox,
- waits until Trutzbox is completely shut down (may take up to 60 minutes) and the LEDs are off, and
- disconnects Trutzbox from the power supply.
Now the Trutzbox is ready to be handed over to a buyer.

10.7 Instructions for writing (fuelling) the SSD
To reload the SSD disk installed in the Trutzbox, a "tank USB stick" must first be created, with which the built-in SSD disk can then be "fueled" with a new TrutzBox image (previous image overwritten).
The tank USB stick must be 32GB in size.
First download an image for the USB tank stick from https://trutzbox.de/download/Tank_V67_dev_11.zip. Unpack the file (is then approx. 19GB in size) and upload it with a PC and the program "etcher" (https://etcher.io/) to a 32GB USB stick. Use it to create a bootable USB stick. When you boot the TrutzBox with this USB stick (i.e. insert the tank USB stick into the TrutzBox before the TrutzBox boot), a program is started from the USB stick which copies a TrutzBox image from the USB stick to the built-in storage medium in the TrutzBox.
<
The copy program outputs information via the TrutzBox LEDs with which you can check the copy process.
<
Description of the LED signals (LEDs on the front of the TrutzBox; LED 1 is left):
| LEDs 1, 2, 3 | Meaning |
| 1 an; 2,3 aus | Trutzbox booting |
| 1 on; 2 blinking; 3 off | Search USB stick |
| 1,2 on; 3 blinking | Search target medium (SD card or mSSD) |
| Write image to target medium (takes a long time with old TrutzBox, since USB2 is still..., on new TrutzBox with USB3 stick approx. 5-10min) | |
| Check written data (with old TrutzBox, since USB2 is still very long..., on new TrutzBox with USB3 stick approx. 5-10min) | |
| 1,2,3 blink synchronously, 3*beeps | |
| . | |
| Error | |
| outside inside rhythm: 1 on, 2 off, 3 on |
Error display is shown together with beep every 60 seconds. Copy did not work. |
Then remove the TrutzBox from the power supply, remove the USB stick, reconnect the TrutzBox to the power supply and run the TrutzBox setup again.
Please note that the TrutzBox generates new certificates during setup. Therefore, you must delete the previously imported certificates on your mobile devices before setup.
It may happen that the TrutzBox does not want to boot from the USB stick when "refuelling". Then only a serial cable helps to connect to the TrutzBox and adjust the boot order with a terminal in the TrutzBox-BIOS. Or remove the storage medium and send it to us.

10.8 Installation and start of PuTTY (terminal program under Windows)
As an alternative to Webmin, it may be necessary to execute commands directly on the Trutzbox via SSH (secure shell). A terminal program is required for this. Under MacOS, a terminal application is already available by default and can be searched for and started there in Spotlight with "terminal". Under Windows, the "PuTTY" terminal program must first be installed.

12 Information and statements
12.1 Headline information that PGP- and S/MIME-encrypted emails are no longer secure
The last few days have seen headlines saying that PGP and S/MIME encrypted emails are no longer secure. This raises the question of whether this also applies to the TrutzBox.
First, a brief explanation of how attackers can read traditional PGP or S/MIME encrypted emails: The prerequisite is that the attacker can intercept and manipulate the encrypted e-mail during transmission. Since with conventional e-mail transmission at least both the sender's and the recipient's e-mail provider are able to do this, this prerequisite is always met. The attacker then inserts a link into the encrypted e-mail that is retrieved by the e-mail client and thereby sends the e-mail to the attacker after decryption. Details about this attack scenario here: https://www.efail.de/
How does e-mail work with TrutzBox?
The TrutzBox is a server that can also send and receive secure e-mails. When designing the TrutzBox, we attached great importance to the fact that communication via the TrutzBox is not only easier to use, but also offers even more privacy than PGP-encrypted e-mails. This was achieved by TrutzBoxes exchanging their e-mails via Tor hidden services. In contrast to PGP-encrypted e-mails, the TrutzBox offers the following advantages if both sender and recipient have a TrutzBox:
- the key management is fully automatic. The user never comes into contact with any keys. Unlike PGP-encrypted emails, which require manual key management on all devices in use.
- no extension is necessary on the end devices (e-mail clients). All email clients can still be used in their full functionality.
- an attacker who can monitor Internet communication cannot see that an e-mail is being exchanged here, nor which IP addresses are communicating here. With PGP-encrypted emails, anyone who has access to the mail servers or Internet connections can read all meta data of the mail.
- for security reasons the TrutzBox always encrypts e-mails additionally with PGP
- since the TrutzBoxes exchange e-mails via the Tor network and there is no "e-mail provider" in between, no third party can change the e-mail on the move.
As a result of this last point: if the communication partner also has a TrutzBox, the e-mail cannot be manipulated while on the move and is safe from this attack,
These same features are also used by the chat function of the TrutzBox. Due to this increased security against PGP, the TrutzBox is also used by journalists, doctors, lawyers... which require special protection.
If the communication partner does not have a TrutzBox, the TrutzBox can also send and receive PGP-encrypted e-mails via normal mail servers and automatically encrypt and decrypt them. In this case, the email client retrieves the decrypted email from its TrutzBox.
But since in this case the PGP-encrypted mail is exchanged with a normal e-mail account, it can be manipulated on the way. The TrutzBox decrypts the mail correctly and does not send any mail to the attacker, but if the e-mail program on the client is configured to load references from the e-mail, then the attacker would also receive the mail from the e-mail client. If, as in this attack, the mail was tampered with on the way, the TrutzBox would detect this, however, since it cannot verify the signature and would mark the mail accordingly.
However, it is quite easy to fend off this attack. To do this, simply deactivate automatic reloading in the e-mail program.
