OpenVPN server works but Wireguard Server has no internet

I’ve successfully managed run an OpenVPN server on my GL-MT300N-V2 but I’m having no luck with the Wireguard server.

I’m able to connect to the server but I’m getting no internet connection once I’ve connected.

Anyone got any advice on setting up the Wireguard server? Are there more steps involved compared to setting up the OpenVPN server?

You can ssh to the router, run the command:
route -n

Then show the results here.

How do I even SSH in though? I’ve only configured the router on the setup page?

You can refer to here, ssh to the router
