I am setting up a VPN using WireGuard, and the incoming connections will be coming from an Internet accessible NIC (eth0), but I do not want to have that LAN to be the network that is accessed over that VPN tunnel.
I want another LAN to be seen by the VPN Tunnel and its associated IP addresses (eth1).
My setup so far, is 2 NICs, eth0 is the primary LAN and eth1 is the LAN I want to be seen by the VPN.
I am not sure what I need to configure and where ?
