difficult problem with DNS and Mail

When I went live on the net with my ISDL link, security was a
primary issue. Previously, with my 24*7 PPP connection thru
work, I was behind their firewall.
It took me awhile to set up my DNS here, the `BIND AND DNS' book
was|is great, and I'm going to buy the new edition that covers
BIND9. But that may not answer the question I have now.
I have set up a separate machine that will be my DNS and Mail
link. My ISP alloted me 4 IP's, X.Y.Z.248-251. The new machine
plugs into my router as fubar.thought.org, 216.39.168.249, and
reaches the net, no problem. *This* box, tao.thought.org, (248)
is currently serving everything. DNS, Mail, and web.
I want to have FUBAR be my gateway and put TAO behind a firewall.
(I'll set securelevel=2 on fubar, so even if somebody cracks it,
he won't get far.)
Eventually, I'll go back to my 10/100Mb hub and NIC's; but for now
my questions are:: how to set up fubar as a gateway; and how to
have fubar route everything, including mail, here. (Sorry if sendmail
is OT.)
thanks for any insights!
