I'm going to get right to the point: after trying multiple times with many different games, almost every multiplayer game that one would actively interact with other people in (such as Unreal Tournament 3 or Maplestory) tells me that I can't connect to their server. I open the ports they say that I need to open, and I have tried turning my firewall off, but none of these seem to work.
The really strange part is that I can still play Runescape without any problems. Anybody have any ideas as to why I have this problem & how I can fix it?
