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?
