Precisely. Port Forwarding either works or it doesn't, once it's setup it doesn't just fail, it would never have worked in the first place.
Internet is the same and so is Sony Network. Let's do a review of points of failure here;
Local Network - Nope, able to ping router and get on internet
Internet - Nope, able to get on internet
Sony Entertainment Network - Nope, able to sign in and play just about any other game
Treyarch Servers - Woops, Housten, we have a problem!
