(Sorry for the off-topic post, but I know people are using IPNAT under NetBSD)

I've got a SPARCstation clone here at home and a couple of Macs on an internal
Ethernet.  I've got IPNAT running on the SPARC clone and I'm using 192.168.1.x
for my internal network.

Up to now, everything's been just peachy with this setup, modulo a strange
problem with Web pages whereby the last image on each page never seems to
be completely downloaded (like as if there's never a final FIN/ACK handshake
negotiated for the page).  I've always hit "Stop" and then "Reload" or just
clicked on the unfinished image to work around it.

Today I loaded Rhapsody DR2 on my G3 Mac.  Now I can't FTP to anywhere because
anything - like "dir" - that uses PORT commands issues PORTs with, of course,
the real address of the machine.  So it issues "PORT 192,168,1,3,4,4" commands
and the target host dutifully tries to send ftp-data packets off to
instead of back to my IPNAT gateway, naturally.

I'm sure I'm not the first person to run into this problem!  Is there some
way to tell IPNAT to change these PORT commands on the fly (I doubt it), or
do I have to tell the Rhapsody box to use my IPNAT host as an FTP Proxy of
some sort?

Thanks for any advice,
