I have alot of friends on xbox live and there is only one friend that i cannot connect to. So please, before i am told to check my damn nat settings I CAN CONNECT TO ALL MY FRIENDS BUT ONE. Whats the problem? I play COD and have no problems joining multiplayer lobbies or connecting to all but one of my friends parties. This friend of mine can also connect to everyone but me. Wouldnt be such a big deal but when i PAY for a service i expect that service to be provided!
