make ports available just in vpn tunnel

Hi, some kind of new to WireGuard.

I would like to make a few ports on my host just available to the WireGuard tunnel.

The tunnel is working, for ssh for example but i cannot get the traffic from a local web server over it, without opening a port to the whole public.

Which WireGuard ore firewall configurations do i have to set to make it working.

(host system is Linux just to be clear)

Thanks for help!
