I just had shaw 150 installed with the CGNM-2250 router, I bridged my older netgear RV6200 so that my xbox is plugged into it directly, speeds are fine however the NAT has now gone to strict. Ive looked around on the forums and am still unclear on how to get the issue to resolve, I tried the IP passthrough and that didnt seem to work. If anyone could shed some light on how to proceed it would be appreciated. Also read about Shaw enabling a second IP address??
