I've tried everything, yet my NAT is still closed. My router is a Netgear one. I had all the ports forwarded, my Xbox's IP (which is static) as the default DMZ, and then I had UPnP on. Though the article said that they all sort of cancel each other out, so I removed all port forward settings and turned off UPnP. I reset my router and modem, and restarted my Xbox. Still have a strict NAT. Help? I've been trying to fix this for a long time, and this is becoming very tedious and frustrating.
