Can't play BO2 Zombies
-
I cannot play zombies with my friend. Whenever I press join on his session, or he tries to join me, we get the same "Unable to join game session" error. UPnP is enabled, I have checked my firewall and I have forwarded all the necessary ports. I am at a loss with what to do next - any suggestions would be appreciated.

join on his session
what if you host? it won't matter if you forward all ports if your friend who is the host doesn't it won't work.
