Thats basically what did soon as you get UPnp your sorted lets hope its does stay like this now i think mine will as its now a static IP and shouldnt change.
I'm not really sure if setting Static IP Address makes a difference as my router does it automatically for me.
good news mate. computers are hard to understand lol
Not really. I had done everything that I was supposed to (UPnP Not Available -> Open Ports Instead and Forward) and it still didn't work. Luckily, UPnP works again.
I had the same issue on my PC a couple of weeks ago with UPnP not working for a program, but opening ports and forward them worked flawlessly, unlike PS3...
