I've got a VPN running between my home in TX and my employer's
site in Atlanta, using PPP-over-SSH. Or at least I did until
recently; I think the nazi M$ network admins in Atlanta
discovered my Red Hat VPN server lurking on their network and
took it out and shot it :-(

Anyway, I had to set up a forward-only DNS server on the Atlanta end
of the link, because they wouldn't add a route for my net to the real
DNS server. I'm not aware of a way to make a particular name request
use particular DNS server; I just listed my forward-only one second
in /etc/resolv.conf and that worked pretty well (especially since I
also have a caching DNS server on my local firewall -- I only had
to wait for the very first attempt for each Atlanta name to
timeout on my ISP's DNS server and go to my forward-only server
in Atlanta).
