Plutonium

if the network tab in the plutonium menu says port 28960, is that what i should put as my port when i port forward and in the prot forwarding rules?

Trying to host and use the double click join friend method.

I've restarted, I've port forwarded, I've disabled and reenabled UPNP.

I've tried with host LAN, i've tried with host online, I used xpartygo.

I just don't know what to do anymore. I really wanna host custom zombies games with my friends but nothing works. Every time I've tested it was just vanilla nacht, so maybe that's a problem? Idk

I would really appreciate it if someone could help or offer any new solutions. Thanks!
