Xbox 360 moderate NAT with ASUS RT-N66U

[Spac3Monkey]

Hi all
I have recently purchased an ASUS Dark Knight. I have everything setup but my Xbox shows as having a moderate/strict NAT.

I'm not sure on how to resolve this. The firmware is up to date, UPNP enabled, NAT enabled, not sure what else to do to be honest, Amy help would be appreciated

Thanks

The built-in "firewall" is blocking ports. First, please disable uPnP.

I believe the ports to allow through unfiltered are:
Port 88 (UDP)
Port 3074 (UDP and TCP)
Port 53 (UDP and TCP)
Port 80 (TCP)

These will connect you without issue to the XBOX live service.

Try that and report back.
