Ok, I have a D-link router DIR-655 and I'm having a problem. I have an Xbox 360 I use a wireless adapter. I can connection to xbox perfectly fine. Once I get on a game to play with a friend or two I can connect to one friend but when the other friend joins the match I automaticaly get dissconnected. I figured it was my firewall and I don't know what to do to turn my firewall off. Can someone please help.
