PS3 NAT Type 3 problem

[kurosagi01]

Hey guys as some of you may not know i got a PS3 20gb model 1st gen model which has no wireless built-in;its been connected via my laptop wireless for couple years and i was able to join my friends games etc.
But now after formatting my laptop and sorted connection i have noticed my NAT type is 3,which is a problem for me since it does not enable me to join my friends games or form party on games.
I have enabled internet sharing from my laptop wireless,which allows me to play online on the ps3 but because my NAT type is 3 i cannot create or join friends party. =(
my router is: Belkin F5D8233-4v3(01)
and i am connected via CAT5-E from ps3 to laptop.
Any help be appreciated to change my NAT to 2 because this is upsetting as i bought PS3 to play online with friends.
my laptop spec: HP Compaq 6735s
AMD Turion X2 2.0GHZ|4GB DDR2 667|250GB HD|ATI Radeon HD3200|Windows 7 Ultimate 64-bit
