Alright as it turns out my internet had a small breakdown in service earlier last week - as a result something has gone haywire in my connection in particular - all the port forwarding that I've done before was PRESENT in the box menus but I had to delete all of them and reenter them manually again.
What's weird is in the Black Ops lobbies I was notified that my NAT was OPEN and same in the AC:R when it was most certainly not, only after deleting the old port forwards and reentering them anew was I able to open my NAT officially.
So end result : even if the NAT appears to be OPEN, delete all the previous port forwards and reforward them.. twice.
Pissed me off to no end after all the troubleshooting I had to do yesterday, it's like finding out that you were meant to take a train after a cavity search at an airport.
Disconnect and self destruct, one bullet a time.
