Whenever I try to join someone's party or game, I can never connect.
My NAT is Open, I have checked dozens of times. When I try to join a party, it sits for about 20 seconds then says, "Can't connect to Xbox Live party"
When I try to join a game, on Modern Warfare 2 it says, "Joining Game session attempt #1" then in about 10 seconds it says, "Joining Game session attempt #2" then it says, "Unable to connect, no game host found" or something like that. Then on Black Ops, it says "Unable to join because the server you tried to join does not exist"
Can anybody help me?
