The same thing happens with active FTP. Only since switching to a sparc64
NAT machine, mind you.

It hangs at the quit command, whether I use active or passive. Different ftp
servers around the world hang in different places, but the only connection
problems I'm having all involve ftp. I am therefore inclined to suspect the
ftp proxy code in ipnat. If you have a more likely suggestion as to where
the problem is, I'm all ears.
