Two comps, same lan, WC3

[Callipygous]

me and my roommate are trying to play WC3 custom games on battle.net. I can host games, and people can join them. Port forwarding is set up for that. Henri can also host games, and people can join them.

 

but sometimes neither of us can join a game that the other is hosting. We have made it work in the past, but cant figure out any pattern as to how. we have played a game, it ended, and then we go to start another game and it wont let one of us join. No changes made to our settings in between.

 

I am at a loss, and so I turn to SFN for guidance. I can provide details of the portforwarding i have set up if that would help.
