Can't enter race online

[fabdtm]

I was wondering if anybody got the same problem as me.
I can download the update,i can connect to the gt tv or news, i can even play in the online time trial, but i never succeed in entering aN ONLINE RACE.

The searching player comes out, then the joining race sacreen,and after 1 or 2 min i got an error message.

Thanks in advance for your tips.

getting that error pop-up once in a while is normal, but if you cannot connect at all, not even for one game, then you might have a problem.

Is your PS3 stock? I meant with absoultely no software or hardware hack.

Yes my Ps3 is stock, japanese model purchased in HK, game imported from Japan.
All other games i got work perfectly online, but with GT5 can't enter a single online race.

Everything else online is working fine though???

I justtested my connection and it says Nat 3,does anybody knows if it is important,and more importantly how to switch to Nat 2?

thx
