Thank you for that, It works great with the PS3 Test Connection as that was failing on me, Also for them people that need NAT: Open for the Call Of Duty: Black Ops 2 game from Moderate to Open, Heres what i did... As i dont wont my PS3 in DMZ as is a big security risk from the bad internet.

Afther that is done, You need to give permission for Pings as Black Ops 2 give you them connection bars.
Go to
Firewall - Rules > WAN
Add new rule
Protocol: ICMP
Description: PS3 Ping or you can leave it blank.
Save.
Apply settings
Fire up the PS3 and you should see NAT: Open on the bottom.
