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

To connect more than two FRITZ! networks via WireGuard, you must set up a VPN connection to the central FRITZ! network in each of the FRITZ! networks. You can set up the individual VPN connections as described in the guide Setting up a WireGuard VPN between two FRITZ! networks.

Example:
To connect the three FRITZ!Box networks "FRITZ!Box Headquarters", "FRITZ!Box Branch", and "FRITZ!Repeater Branch" with each other via WireGuard, set up the following VPN connections:
- In "FRITZ!Box Headquarters" configure a connection to "FRITZ!Box Branch".
- In "FRITZ!Box Headquarters" configure a connection to "FRITZ!Repeater Branch".
- Only if devices in one branch should be allowed to access devices in the other branch, configure a connection to "FRITZ!Repeater Branch" in "FRITZ!Box Branch".
