Can't connect to local device via VPN Client router but I can with the wireguard app

[YouGotName2022]

If I connect to my VPN Wireguard server via a wireguard software app I can connect to it. However, if I am connected to the same wireguard server via another gl.i net router(running as a wireguard client router) I can’t connect to them via the same IP address…

Any suggestions on how to fix?

Thanks

My Client device, the Certa, is known to preform with VPN providers using a MTU of 1320. YMMV. Server …
