Okay, while I'm up north the wi fi we use is a cisco linksys and I have tried enabling DMZ on it but it still doesn't work. Can someone give a very detailed guide as to how to enable DMZ properly or give an alternative solution to fix my problem? I'm here till Sunday and I'm dying to kill zombies online again. I get the "your connection does not support online multiplayer" error
I would like an answer to this question as well. What should we do to get multiplayer working? Is the Cisco Linksys wireless-N router bad?
