ok. even though the problem has not been solved. i fell ive learned a lot and im close to figuring it out.
i still get the same error that my game cannot conduct udp port check. so i took your advice and opened some ports. this link explained how i did it
Port Forwarding for the Netopia 3347NWG
it also recommended i use a static ip which i have still to perfect this because when i did use a static nat, my nat connection test failed. and the same problem occured. i still feel this is a problem to do with my interent connection. and not my ps3. but i could be wrong,
have you any sugestions
