Been getting NAT type 3 constantly and it wasn't an issue till I tried playing UC 2 online and it didn't work at all. So I went around looking for instructions on the stuff and I've basically tried everything:
Set up a DMZ for the PS3, opened the PS3 UDP and TCP ports, turn UPnP on and then off and reset the modem, the ps3, tried to use the modem as a bridge, nothing's worked.
It even gives me type 3 NAT when it's connected directly to the modem which doesn't make any sense. When I called ATT (one of the worst customer service companies) they told me they have a technician that will guide me but I had to pay 39.99 or 99 dollars or something but I had already hung up at that point.
Anyone else here that has had this problem? It's only an issue when I try to play online and it still happens even when I don't use the router and connect staright to the modem.
Thanks to Blacksaber for the sig!
