> I had a router from BT that despite having won awards, could not resolve its external IPv4 address internally. It knew what its external address was and knew that it had to DMZ everything to an internal address, but if you attempted to resolve the external address (expecting it to go to your DMZ'd machine), it'd fail. to be fair, I've got $1000 cisco hardware that can't wrap the external IP like that...
