HAT??

And yes I have a NAT implementation that runs entirely in
kernel land, and it does all the footwork on ip, udp, tcp,
ftp, irc, realaudio etc etc. It soon will support multible
ip# to multible ip# and other fancy stuff.
The problem is that the code is now proprietary as well, so
I cannot release it either. However its not difficult to
do as julian states, and I still think it should be in
the kernel (or at least its needed in the apps where
its used here).
