Changing the FRITZ!Box's IP address

In the factory settings, the FRITZ!Box uses the IPv4 address for the home network. You can change this IP address to

  • connect the FRITZ!Box with another FRITZ!Box network (LAN-LAN linkup) via VPN. The IP networks of both of the FRITZ!Boxes may not be identical.
  • integrate devices into your home network that have fixed IP addresses specified by the manufacturer that you cannot change.

Requirements / Restrictions

  • The guest network of the FRITZ!Box has its own IP address range that was assigned by the FRITZ!Box and cannot be changed.

Note:All instructions on configuration and settings given in this guide refer to the FRITZ!Box 6820 LTE v2 and v3 with the latest FRITZ!OS, the FRITZ!Box 6820 LTE v1 may vary.
