Fraser my problem is resolved
After going back to bleeding edge/auto cloud my nat type 2 returned on my ps4
I still had a moderate nat in black ops so tried rebooting the router, That did not work so noticed on my upnp settings that i wasn't getting port 3074
I unplugged the ps4 power cable, disabled upnp and then rebooted the duma and re enabled upnp again and a open nat on black ops returned
Thanks, Relentless
