You can edit the VPN connections configured in the FRITZ!Repeater as follows:

• IPSec connections to other FRITZ! networks (LAN-LAN linkup) and connections to a company VPN can be edited in the interface of the FRITZ!Repeater under "Internet > Permit Access > VPN (IPSec)".

• IPSec connections for FRITZ!Repeater users, for example for a mobile device or a computer with Linux or macOS, cannot be adjusted in the FRITZ!Repeater.
• In the case of WireGuard connections to individual devices, only the name of the connection can be changed under "Internet > Permit Access > VPN (WireGuard)" in the user interface of the FRITZ!Repeater.
• With WireGuard connections to other FRITZ! networks or a different router (LAN-LAN linkup), you can edit the name of the connection, the option "Allow NetBIOS over this connection", and the devices that can be accessed over the connection under "Internet > Permit Access > VPN (WireGuard)" in the user interface of the FRITZ!Repeater.

If you want to adjust other settings, delete the VPN connection and then reconfigure the connection with the new settings.
