| Contrary to what Scott just said, it's not each application that has

Isn't it the case that some applications, like ftp, encode ip address
and port information in application layer traffic, which NAT has to
account for?  Linux seems to have code to handle that sort of stuff
(linux/net/ipv4/ip_masq*).
