Private Multiplayer Game

Ive tried to get one for me and my friends to make a machinima online but it doesnt work. We’ve tried Hamachi and we tried joining by pressing join gmae and using the console like connect idk what to do so if anyone has some advice please comment.

The main problem everyone experiences with self-created multiplayer games is that other people can’t see it in the list and direct console connection fails. This is usually because the host hasn’t forwarded specific ports on their internet router which basically allow other computers to connect with it.
