I have a Linksys WRT54GS with fully udpated firmware. I tried port forwarding, and when that didn't work I reset the router to factory defaults. Still nothing. I have Vista and only run the default OS Firewall along with Symantic AV. Windows Firewall says that Sins has full access.
No matter what I do, the game won't connect to Ironclad Online. I am able to play every other online game I can think of with no problems (WoW, CoD4, any Steam game, etc). What is so different with Sins that it requries me to turn my computer and network upside-down just to have a chance at connecting?
