The only thing I found about the WAN setup on the router is:
Connect Automatically, as Required =Yes
Disable SPI Firewall = No
Default DMZ Server ... = No
Respond to Ping on Internet Port = No
MTU Size (in bytes) = 1500
NAT Filtering = Secured
Do you think it might work if I change my router NAT Filtering to = Open?
Maybe I should just try plugging my modem directly into the xbox (taking the router completely out of the picture) to see if it solves the problem. Although, that would not be a workable long term fix.
Log into your netgear router and go to the Router Status page. Under IP address if you see an IP in the 192.168.x.x, 172.16.x.x through 172.31.x.x or 10.x.x.x) than you are having the double NAT issue previously mentioned. A solution to this is to either directly connect your Xbox to the canopy modem or to purchase a public IP address from your provider.
If you do not see the above scenario (ie an IP address in a different range than mentioned) you may need to assign your Xbox a static IP address and forward UDP ports 88, 2074 and 3074 and TCP port 3074 to the unit (I had to do this with mine as I was having connection issues). You can find tons of information off of Google on how to do this.
Hope that helps!
