Well, that's pretty funny!  I've been digging around since then to
see if I can figure out a fix for it.  I haven got it yet, but I'm
working on learning how ipchains works ...

Nope.  In fact, after a while, I noticed that the eth1 interface also
seemed to be nonfunctional. Not that ifconfig saw anything wrong with
them, and netstat seemed to also think they were ok.  But all I could
ping  was  the  local  address,  and communication with the other (2)
machines on eth1 didn't work.  Maybe I don't really know how to  turn
the  filtering off correctly.  The HOWTO that I've been reading seems
to say that "ipfwadm -I -f" does it, but it doesn't seem to fix  this
problem.

Anyhow, I finally decided to try the Microsoft Solution,  and  did  a
reboot.  It all came up working.

Maybe I'll eventually figure out why ...
