When I try to join a game in Call Of Duty Black Ops 2 Zombies with my 2 friends, it won't let me into the game. They are able to play with eachother, but when they get into the game it says I timed out and if I try joining again, the same thing happens. My NAT is Moderate, my one friend's NAT is also Moderate and the other friend's NAT is Strict. I'm not sure if this has anything to do with the NAT Type. Ever since I got the game this has been happening. Please help me if you know how to solve this or maybe have the same issue. Thank you!
