I have a Wireless D-Link DIR-615 router, I can't seem to get Nat 2, I tried setting up the DMZ way but the router is not getting the PS3 when I set the static ip on it but when the randomly generated ip given by the DHCP my router sees it but I can't use that ip as the ps3 gets a new ip everytime I turn it off. Any suggestions I can't even play demos online... PLEASE SOMEBODY HELP

Seriously three steps because I heard people download firmware and other stuff plus is the Xbox Live setup harder?
