No need now
I can avoid that annoyance with "dhclient ath0".
I got the whole thing to work just fine once I used a co-worker's home machine for the tunnel. (That is how I'm posting now.) And in a day or so I'll be on the plane back. This doesn't come up very often, I'll deal with it when it does.
Cheers,
Ben
