XBOX Live Strict NAT after upgrade
built on Fri Dec 17 02:16:21 EST 2010
Anytime I do an upgrade to the build the Enable Disable UPNP button must be unchecked then click the change button and then click the enable button and change and I get an open NAT status from the Xbox live service.
Static IPs or even assigning them based off of mac address is not necessary.
A reboot does not give an open NAT either, the service must be stopped and restarted in order to get an open NAT.
Hope this saves someone some time.
