Try changing your DNS.... its set to your router....
try using Google's DNS
Primary - 188.8.131.52
Secondary - 184.108.40.206
I've yet to come across any other DNS address that delivers better network consistency.
Whats your modems make and model?
Ok, so I went to the main modemn page for my modemn, I messed around but didn't change anything. Then I came back to my ps3 and made a new connection settings, but did the "Easy" instead of "Custom" and it gave me a nat type 2. I have no clue what I did to acheive this.
I have tried everything on the internet to get this to work, and still everything I have tried I still get NAT 3 type.. I have a Belkin router Model : F9K1103V1. I'll attach a picture of the setting of it on my ps3 and the ports I forwarded on the router settings. Any help would be greatly appreciated. Thanks
Default Router IP is 192 168.2.1 ... "2.1", I guarantee he's double NATing. He's got his router plugged into a Modem/Router(Gateway Modem) The gateway device has the 192.168.1.1 or 0.1. A network inside a network... awesome fun, Bridge that Modem Gateway to get things as they should be.
