very good summary :)
Mark can start by drawing a diagram of the setup, configuring the DHCP an
DNS and firewall properly.
Ad DHCP Mark, you can setup a range with static and a range with dynamic IP
addresses. All that has static address must still be in the DNS to be
I did not get it at which level you split the network in two
(internal/external or private/public) - I assume this is the firewall. It
also means the firewall has 2 interfaces - one for internal and one for
external network. You need a good IP-tables setup to make interconnect
What I describe is the most simple scenario and as Henning mentioned forget
the dns caching for now, until all this stands. I advise start with
DNS/DHCP in the internal (private) network.
