Lag Multiplayer

I just purchased this game wanting to play with friends. I check my router and UPNP is enabled. I try to port forward but it ask for external protocol which I’m not sure what it is. I’ve tried opening ports on firewall on windows and on router. I have am having no luck. I can play online it just is very delayed and sometimes hic ups until it catches up. Any ideas?

Nothing. Can’t figure it out.

Have you read Multiplayer - Common Solutions?

Yes. I cannot get upnp to work. I’ve even tried opening ports. I’m not sure if I’m doing it correctly as I got a new router.
