> Nat is ip to ip address translation. Most proxies do Port Address

Translation: "Instead of acknowledging that other NAT technologies were
already available I'm going to redefine NAT to only mean IP-level NAT,
even though this list is full of people smart enough to recognise I'm
blowing marketing smoke."
The PIX solution is certainly convenient, but it's not the only way to
do things, and some people might want to use proxies rather than an
address rewriting filter for the same reason that some people use
proxies even when NAT isn't a requirement.
There are plusses and minuses to both kinds of technology, but there's
no benefit to playing name games.
