I have tried all the steps and suggestions posted above, alas, nothing happened. I am not an avid online gamer but I had to try out COD4 online---that's why I had to surf the web to check for some solutions.

I have come to the conclusion that this ISP just ruined what could have driven me to play online. These guys block sites, block pop3 emails, block online file transfers, block VOIP...and now they block PSN! Geez..What did a casual console gamer ever do to deserve this?!! I partly blame UAE PS Support for not taking immediate actions.

I am quite sure Du will let you log on PSN. Be careful though, exceeding their bandwidth limits would be a real pain in the pocket. Unlike our "beloved" ISP, I think Du's rates aren't fixed at all. This is one reason why I've been really skeptic on joining the Du bandwagon.

If you somehow get your way around it, could you kindly post the solutions on this same thread? I'll constantly be checking out on this one. Thanks a lot!
