Of course NAT causes all sorts of damage to all sorts of protocols, as
the debate over VPN software demonstrated, nevermind voice applications
and peer to peer networking. It also has substantial implications for
mobility. This has all been well documented, as have workarounds.
Having yet another argument about this on nanog is a waste of bits (to
which I freely admit I'm contributing). Let me suggest we not bother
with the rest of the argument, but just have people search the archives.
