You may not need to operate two separate DNS servers. You may place a "hosts" file with IP to hostname resolution on the inside users' machines. The "hosts" file is checked before DNS, so inside users with "hosts" files see inside (RFC1918) addresses and users outside see outside (NIC registered) addresses. Refer to the MS sample hosts file, "\Windows\hosts.sam" on almost any win32 machine. ===== Mike wrote: We are running a 192.198.x.x private network. We also have 4 authentic class C's. We just decided to implement our proxy server. Right now, the Imail server is on real IP#'s - and we now want to put the server on the 192.168.x.x network ASAP. We will be running 2 DNS servers - one behind the proxy, and one in front of it. Obviously the one in front of the Proxy will handle all incoming Internet requests, and the proxy has ability to map real #'s to private #'s. I am just curious on how I should tackle this issue...
