I don't want to run anything unnecessary in the DMZ.  It'll have a
webserver serving a mirror of the one inside the LAN.  Users (like the
kids) will update the internal website and rsync will update the public
one.  It'll also have a mailserver whose only function is to receive and
filter incoming email.  Since it'll be exposed to the net, I don't want to
leave anything of value on there.  The internal server serves IMAP for
users so it holds the email.  It runs all sorts of other services too,
none of which need to be exposed to the net.  The internal mailserver has
been running for years already being fed by fetchmail/pop so it's no extra
work to keep twin servers.

Once I have the DMZ machine fully configured, I'll probably store its
config on the LAN and push it regularly out to the DMZ as another security
element.

This is all overkill for a home environment but it's fun and a useful way
of keeping up to speed...
