Online multiplayer thread

[Stampedo]

Hello,

Few people on the forum had issues with online multiplayer, thought it would be better to gather everything in a single thread.
Just copy-pasting mine, feel free to add yours:

Error when trying to host a game (pressing the button "host")

Would someone have tips regarding the way to host/join a game?
I'd like to play with a friend, we're in the same room using 2 different computers, but it keeps crashing, there's only a few options to work with. I understand it's still a very early feature but I'd be glad if someone could make some suggestions.

Ports are opened in the modem and the firewall.
Whenever I try to join a game, forge crashes.

What should I write as for the Hostname? Is that of any importance?

Thanks!
