People purchaced the service on the understanding that they would get a Internet address. A address behind a NAT is not a Internet address, it's a *shared* Internet address which is a very different thing. > Many/most people are _already_ behind a NAT gateway. They are behind NAT44 which they deployed themselves and control the configuration of themselves. They can direct incoming traffic as they see fit. They are NOT restricted to UDP and TCP. NAT444 is a different kettle of fish. There are lots of things that you do with a NAT44 that you can't do with a NAT444. If all you do is browse the web and read email then you won't see the much of a difference. If you do anything more complicated than making outgoing queries you will see the difference.
