I built a new computer recently. On my old computer I forwarded the ports for Bo4 so I could have an open NAT type. And it worked fine my NAT type was open. Then I built this PC, checked my IP and all that to make sure the ports were still set up correctly and everything was good. I checked my NAT type and it was strict. I have tried opening every single port for Bo4 still no difference. I turned my firewall off for a few minutes still strict. I even put my pc into DMZ for a few seconds which I know you really should not do but even then my NAT type was still strict. I can't even get it to moderate. Please help me.
