You can protect the user interface of your FRITZ!Repeater against unauthorized access with a password. If you did not assign a password, after setting it up you must use the password and, if applicable, the user name of the FRITZ!Box to log in. If you forgot the password, reset the password or load the factory settings. Then you can log in again and set a new password.
If you changed the default password given on the underside of the FRITZ!Box and forgot the password, reset the password or load the FRITZ!Box's factory settings. Then you can log in again and set a new password. If you did not assign a password for the repeater's user interface, you must use the password and, if applicable, the user name of the FRITZ!Box to log in. In this case, use the FRITZ!Box password to log in.
1 Using the FRITZ!Box password
If you did not assign a password for the repeater's user interface, you must use the password and, if applicable, the user name of the FRITZ!Box to log in. In this case, use the FRITZ!Box password to log in.
2 Resetting the password
If you are offered the option of sending a push service mail, have an email sent to you that contains an access link that you can use to reset the password:
Open the user interface of the FRITZ!Repeater.
Click the 'Forgot your password?' link.
Click the 'Send Push Service Mail' button. If the button is not displayed, the 'forgot password' push service is not configured.
Call up the email with the same device you used to request the push service mail and follow the instructions in the email. If you did not receive an email, either the the email account information entered for the push service is not correct, or the repeater is not connected to the internet.
Important:The email may have been classified as unsolicited advertising (spam). In this case, also check the spam folder of your email inbox.
3 Loading the factory settings
If you are not offered the option of sending a push service mail or you did not receive the email, you cannot open the user interface again until you load the factory settings:

Introduction
Both the Fritz!Box and the Fritz!Repeater have apacket trace featurethat works by requesting a special URL that returns a traffic trace for a specified interface in the form of alibpcapformatted file. When the trace is terminated, the saved trace file can be viewed using software such asWireSharkthat displays the traffic in a readable form.
While this feature is quite useful, it has the major disadvantage that one cannot view the trafficin real time. The trace must be started, run for as long as is required, and then stopped. Onlythen can Wireshark be started in order to display the trace.
NAT32 can request a trace from the Fritz!Box or the Fritz!Repeater and then pipe the receiveddata to a shell command (tdump) that decodes the data and prints it to the standard output device.The standard output can be redirected to a NAT32 Monitor window for subsequent display.The display can be started and stopped as needed and can also be saved to a file for subsequentexamination.
Because the NAT32 shell (unlike the Windows cmd.exe shell) executes each commandof a pipeline in a separate thread, the display of the trace data occurs in real time and the user canimmediately notice (and respond to) any unwanted Internet traffic originating from connected computers.This feature can be very useful for detecting viruses and applications (e.g. Skype) that may consume largeamounts of DSL bandwidth for no useful purpose (from the user's point of view).
Script Files
A script file to solicit the trace from the Fritz!Box, decode it and display it in the Monitorwindow is shown below:
A script file to terminate the trace is shown below:
The above scripts are contained in files fritz_on and fritz_off and canbe invoked from the main NAT32 web page or the NAT32 Console. Similar files are available for theFritz!Repeater (fritzr_on and fritzr_off).
Notes
If your Fritz!Box requires a password for browser access, please use the NAT32 set commandto store that password in the environment variable fbpwd as follows:
NAT32 Version 2 uses the following TCL script to compute the required Fritz!Box Session ID:
Note the use of the NAT32 command hash in the above script. Because it is implemented in C, itcomputes the MD5 hash of the specified string very rapidly.
NAT32 Version 2 contains additional script files (fritzr_on) and fritzr_xon)that display the trace data in the Monitor window or the Trace window. In the latter case, all packet data is displayed,including protocol headers and payload data.
