Xbox One Moderate NAT -- Black Ops 3

You are supposed to use only one of available options to open ports (i.e. uPnP, Port forwarding, DMZ), not all of them. Pick one and disable the others. uPnP is preferred because it's automatic, but it depends on the quality of Netgear's implementation. If you find it doesn't work, then proceed to port forwarding. DMZ is the least preferred because of the danger of exposing your console directly to the Internet.

It's important to know whether your modem has a built in router. If it does, then you will have to contend with two layers of NAT and, therefore, two layers of closed ports. Bridging the modem disables the router functionality and eliminates this extra NAT layer. One way to tell if your modem has a router is to look at the IP address assigned to the yellow Internet port of your R7000. If it begins with either 10.x.y.z, 192.168.y.z, or 172.16.y.z then the modem is a router. Another way to tell is if the modem has built-in Wi-Fi.
