Many greetings. I'll start off by saying that I love this game. However, I have a problem. My friend and I both have Sins of a Solar Empire, and we've played two games on Ironclad Online just fine. We were both using Windows Vista and after some router and firewall tweaking we were able to join each other's games and play. However, my friend recently installed it on his Windows XP Home Edition desktop. He tried to host a game but I couldn't join and got the error "Disconnected from game server". I tried to host and he got the same error. We can both join other people's games though.

I'm not sure what the problem is. I've opened the ports 6001-6003 tcp and udp on my router and 6112 tcp and udp is opened too. My friend also has those ports opened on his router and we've both turned our firewalls off (Norton for me, Windows Firewall for him).

Any help with this issue would be greatly appreciated
