I have heard it said before that there is significant cooperation and/or software engineering work between some or all of those who make residential gateways and those who make multi-player games to achieve this end result. The opinion I heard vocalised at the time was that it would have been a lot easier to reach this state of affairs if there had been standardisation of NAT in v4 at an early stage. As it is, peer-to-peer apps like games require significant if-then-else to make anything work.

If that was all that was required, you could sell a stateful firewall that didn't do NAT, and everybody would buy that instead because it would make things like iChat AV break less. Apparently there are other reasons to buy and sell devices that NAT (e.g. my ISP gives me one address, but the laptop and the Wii both want to use the internet).
