Wireguard with two WAN

Hi, i would like to setup 2 wireguard instance, have two diffrent WAN and want for both to have one VPN server.
Can you help me a little bit? i tried to create, but seems that i made some mistakes, router got confused and start shutdown the ports .. :confused:

Provide configs?

(Kinda hard to guess.)

Probably not the router.

The WG config and ports shouldld'nt be related...configs would help.
