Ports problem with CoD WaW Zombies iPod

Hi guys, Everytime I try to play online on CoD WaW Zombies on my iPod Touch 3G, It comes up with a message saying.. "Your Current Connection Does Not Support Online Multiplayer."

I think this problem has to do with ports so I need to do some port forwarding on my wireless router in order to get the game to go online.

I've contacted Activision & they've told me that the game uses ports 3074 and 3478 (UDP/TCP) & that I should set my iPod Touch to use those via the wireless router's port settings... Only problem is I've typed those in & set my iPod Touch to it accordingly but that same message still comes up when the game searches for any online matches..

The wierd thing is the game goes online perfectly on my brother's wireless router..

The Wireless router is a 02 Wireless Box II TG585v7 by 02 Broadband

Could you guys take a look at this & make sure I've typed it in correctly so it works?

Thanks & please help me!

So no one can help??

The problem is still happening..

And I'm not the only one experiencing it either as reviewers on the itunes store have left comments on the game page stating that they have the same problem as me..
