@Dear Martin,
You need to set routing rules on the VPN server. The target is the LAN subnet of LT12, The next hop is the VPN tunnel IP address. You can have a try.
Is the VPN Server set on a Cudy router? If yes, you can set the remote subnet when creating wireguard config.
“I have a configuration where I’m running a WireGuard server, and I connect to it as a client using an LT12 router.
The tunnel is established, the handshake is exchanged, and “data is being transferred.”
I even managed to route all LAN traffic through the WireGuard VPS server’s WAN.
I can successfully ping the WireGuard server (data is going properly do Lt12, i did tcp dump)
However, for some reason, I’m unable to reach the WireGuard client on the LT12 from the VPS server.
I’ve tried many things — I have the exact same configuration on another client, and it works.
In the VPN settings, I also have the Site-to-Site option enabled. Should I change something in the routing?
What I want is a setup where I can access both the WireGuard server and Client B (on a laptop that’s also a WireGuard client)."
