I think all of the NETGEAR Routers now come with UPnPFollow this tutorial and i will show you how to open your NAT.
1. Go to 192.168.1.1 (or 192.168.0.1 - or whatever they supplied you with)
2. Go down to maintenance and 'Attached Devices'.
3. My xbox is named '---' - most xboxes have that default name.
4. Make sure your xbox is located there and is in the IP you selected in your xbox wifi setup.

5. Now go down to 'Advanced' then 'UPnP'
6. If the 'Turn UPnP On' is toggled - then uncheck it and apply. Then when it updates check it again then apply it. That would have refreshed the UPnP.
7. Run the xbox live test and the NAT should then appear 'Open' or atleast 'Moderate'.

Works all the time for me- and my neighbour, so it should work for you
