I think that you need a split dns. You will have a public dns
database and a private one (all in the same bind, you dont need 2
diferent servers or instances of bind, check "view" in the manual).
You can also give a unique name for server who has privates IP, but
a mapped public IP. The "inner" dns will respond with the private
ip, and the public one with the mapped ip address<i>.<br>
</i>Its a bit more complicated, but is the best way to approach this
problem.<br>
<br>
Hope this helps.<br>
