No, actually the ports on my router were responding correctly.

I didn't understand how the ZOMBIES was launched. To me, the ZOMBIES screen was misleading with the way it was laid out.

Why was CAMPAIGN listed on the ZOMBIES screen if it wasn't a ZOMBIES campaign?

So when I clicked on CAMPAIGN (on the ZOMBIES screen) it took me back to BLACK OPs II single player.

I finally figured out that ZOMBIES was played online.
