opendns FRITZ!Box Fon WLAN 7170
5 Nov 2011
This is how I configured my FRITZ!Box Fon WLAN 7170. Using this configuration, I do not need to configure the various PCs in my home network. My phone is connected to the Fritz!Box. You should only do this if you are comfortable with unix commands like cd and vi.
1. Activate Telnet using the telephone with #96*7*
2. In the command prompt (cmd) enter telnet fritz.box
3. If a password is requested, enter your Fritz!Box password
4. Enter "cd /var/flash"
5. Enter "nvi ar7.cfg"
