I've been trying to host a game of custom zombies with my friend, but no success. No matter who hosts, it comes up saying "this session is no longer available". Even without mods, we can't get it to work. The only way we've managed to get into the same game is when we join an official server hosted elsewhere. We've downloaded Hamachi, but really don't know what to do with it when it comes to COD.

Anyone have suggestions? We're pretty adamant about playing since we've all bought the game to do custom zombies together.

When I had dsl I had to forward my ports for cod to play with my friend who had cable. Have you tried that yet?

Not yet, really haven't looked into port forwarding too much, since all the suggestions are tutorials are all over the place. But if it's something you'd recommend, we'll try and figure out how to do that, thanks!
