So i have installed the mod and everything, I port forwarded and tried all sorts of ip. But my friend still cant connect to me. Any help?

It varies

What error is your friend getting?

Are you both using the same connection type (steam or by IP)?
If using Steam, you shouldn't need to open ports as that's on Steam.
If connecting by IP, you'll need to make sure that the port is open and that the game is allowed in firewall.
