The difference is that if a protocol wants to be end-to-end, I can fix a firewall to not break it. You don't have that option with a NAT.
Maybe we want end-to-end to break.Firewalls can trivially be misconfigured such that they're little more than routers, fully exposing all the hosts behind them to everything bad the internet has to offer (hackers, malware looking to spread itself, etc.).
At least with NAT, if someone really screws up the config, the "inside" stuff is all typically on non-publicly-routed IPs, so the worst likely to happen is they lose internet, but at least the internet can't directly reach them.
This has to be one of the bigger reasons people actually like using NAT. ---------------------------------------------------------------------- Jon Lewis | I route Senior Network Engineer | therefore you are Atlantic Net | _________ http://www.lewis.org/~jlewis/pgp for PGP public key_________
