Ok so i got OB yesterday and i tried to play with a couple of my friends. And so this is what happened, they invited me, and i accept, but then it just keep saying that the game session is not available no longer. It does this over and over, i think it is my router because my internet connection does suck. So i was just wondering if this is their sever or my router connection and how do you open the NAT thingy on ps3? Do explain what NAT is because im kinda clueless about what it is?
thanks for answering
