Private (only) DNS server setup?

[Seth Henry]

Guys,
I am trying to decrease the amount of traffic going through my cable modem. 
Presently, I have a FreeBSD 4.10 system acting as a gateway router. It runs 
ipf/ipnat for filtering, and acts as a dhcp server to the internal network. 
I also run ntpd, and have pointed all of my internal machines to the router 
for time services.

I plan to add a caching web proxy, and a private DNS server - which is where 
my question comes in.

I want to run a private DNS server which is visible internally only. Comcast 
doesn't like servers, so I don't want to broadcast any DNS information 
upstream. (this would also be kind of dumb, as the entries would point to 
non-routable addresses)

I also want to create a private, internal zone so that I can stop passing 
hosts files around. (i.e. 192.168.1.1 -> internal_host1, etc) IOW - I would 
like internal machines to point to my DNS server for internal & external 
addresses. If the DNS server (on the router) can't find the address in its 
local cache, I would like the router to retrieve the record, and pass it 
along to the internal machine. In the end, I want to block all DNS traffic 
from the internal network from leaving the network - internal machines 
should only request DNS info from the router.

I am already running dhcpd - so i plan to simply point all of the machines 
to my DNS server. If all goes  well, new machines should be "network ready" 
right after the install.

I have seen a large number of HOWTO's on the web, but all seem to assume 
that you want to propogate internal DNS info back upstream.

Can anyone refer me to an appropriate README, HOWTO?

Thanks,
Seth Henry
