GL-MT1300 no internet via WireGuard

Given

WireGuard server hosted on Windows

GL-MT1300 router acting as a client

The router connects to VPN and the tunnel has some traffic passing back and forth. I can see it is being connected to the server

The issue is that any connected client to the router doesnt get the internet

What am I missing. Some routing ?

Did it ever work or did it just start failing recently? I’ve been having lot of issues myself with Wireguard from past few weeks. I also have a few GL-MT1300 units.

The internet works when I use internet sharing instead of NAT Routing on the server

Trying to understand now how can access internet and local network via the VPN tunner

Any help appreciated
