Im having trouble staying online with my PS3. Every other minute I get disconnected from the playstation store or playing an online game with an error code. When I try a connection test everything is fine, except my communication may be restricted (NAT Type 3). I called sony and they said that it could be my router. Im using a limksys wireless router (WRTP54G). Sony gave me some these port numbers to enter to my router, Tcp ports 80,443, 5223, 10070-10080 udp ports 3478 3479 3658 10070 udp ports 6000-7000 50000 I just don't know what section or what port of the router site I can emter these in.
