Ok, I think that the *most* constructive comment might be something
about pulling ones self up by one's own bootstraps.....  Pithier
possibilies leap to mind too.

What I'm trying to do won't work.  And, now that I see it I'm pretty
much mortified that I even tried it, let alone asked anyone else.

First, I establish an ssh connection to a machine (aka TheServer) and
run a ppp session across it.

Then, I try to add a route that sends all of the packets to that same
machine (TheServer) down the tunnel.  The problem is, of course, that
they can no longer make it to the other end of the ssh session.

Presumably it works coming the other way because the TheServer thinks
that the ssh session is coming from the firewall's address and so it
doesn't get confused....

Sigh.  Bad geek, no beer.
