NAT problem

[RX-7_FD3S]

Ok so the other day I tried to pass from NAT 3 to NAT 1. What I did :

1. Use an ethernet cable to link my ps3 and my router.
2. Set a fixed IP adress manually on my PS3.
3. Open up the port for GT5/PSN on my router
4. Restart both PS3 and Router.

And now I'm still in NAT3, any idea why ?

Turn on UPNP.

Nope it's saying Upnp is not available.

Is UPnP on the router and the PS3? If not make sure it's on both.
