(^&  I *really* need to add that to my signature, I guess.  (If I actually
subscribed to these lists, I'm sure that my mailbox would grow without
bound.  I prefer to read the lists from a web-page for that reason.)

Oh, sorry.  No.  Not unless my machine has supernatural powers.  (^&  ipf
and ipnat were only invoked when I manually ran a script after booting.
(I booted so rarely that I never got around to making it part of the boot
sequence.)  I have since booted the machine, and I'm about as sure as I
can be that there are no firewall rules blocking DHCP.

Yes, I kind of figured.  Alas...

If you mean the bit about all being in one subnet: I checked just now and
that is in fact how they've set me up.  Back in Kansas City, I had a
dialup static IP account.  *There* I had a block of addresses in one
subnet, and a single address (for the PPP interface) in another subnet.
Life was simpler.  (^&
