so, cypher and i just spent the last hour trying to get a coop game going
nothing we did could get it to work. We are always getting a timeout error after a ~15 second countdown.
From reading up on the steam forums (Borderland forums are offline right now), a ton of people are complaining about multi-player issues too. Apparently you have to open up your firewalls wide, enable port forwarding to the following ports:
7777 (TCP/UDP)
28900 (TCP)
27900 (UDP)
28910 (TCP)
and then pray. Well, nothing worked for us and we both gave up. A bunch of people on the forums said there was nothing they could do to get theirs to work... while others said they were able to get it to work.
Anyone else have problems?
