You will have an external name server which has the public addressing and faces the Internet. Internally you have other DNS severs which you list the internal RFC1918 addressing for all systems internal to your network. With things configured correctly any requests while on your intranet will get your internal addresses. Any requests from outside will get the public addresses. One company I worked at had several external DNS servers. Their zones were relatively small just a few entries for the web servers and portals we needed facing the Internet. We also had several internal name servers which had hundreds if not thousands of entries in their zones since we listed all the equipment internal to the company in them. These zones were not accessible from the Internet directly but allowed us to use the same names but serve out different IP addresses. Check out the BIND book from O'Reilly. It has all the information you need for setting this up. -- Scot L. Harris webid@xxxxxxxxxx If you can't be good, be careful. If you can't be careful, give me a call.
