[burns94]

Hi, I currently have a moderate nat type on Call Of Duty Black ops 2 which i would like to change to open. I have followed the post by StephanieG but it is still moderate. Could you please advice me on how to change the nat type to open? thanks

Same is happening here on PC. Only happens in Multiplayer so I no it must be an interenet fault.
