Setting up an IPSec VPN between three or more FRITZ!Box networks

IPSec allows you to connect several FRITZ!Box networks at different locations over a secure, encrypted VPN connection (LAN-LAN linkup).

To connect more than two FRITZ!Boxes with each other via IPSec, in each FRITZ!Box you must set up a VPN connection to all other FRITZ!Boxes. You can set up individual VPN connections as described the guide Setting up a VPN (IPSec) between two FRITZ!Box networks.

Example:
To connect the three FRITZ!Box networks "FRITZ!Box A", "FRITZ!Box B", and "FRITZ!Box C" with each other via IPSec, set up the following VPN connections:
- Set up a connection to FRITZ!Box B in FRITZ!Box A.
- Set up a connection to FRITZ!Box C in FRITZ!Box A.
- Set up a connection to FRITZ!Box B in FRITZ!Box C.
