Editing user_settings file

Hi there, i read a few threads about playing multiplayer without steam, but still i don’t get it. I’ve set everything as Ayazar said here: Multiplayer without Steam?
and still have “somehing went wrong…” error at start. I think that port forwarding isn’t necessary, because we’re on the same local network. Of course we have the same, latest build.
I don’t know how to set it properly :smiley:
