Damian,
That's exactly what I was trying to do :) I've bound two IP
addresses to my DNS server and created two instances of pdns, each
listening to a different IP. I've also create two databases within the
backend, one containing internal (private) addresses an the other with
public addresses.
Internally I have our clients accessing the "internal dns" ip of
our DNS server. I use NAT to allow external hosts to access the second
address (for external queries) on the server.
Chapter 8 in the Power DNS manual lists how to setup virtual
hosts. You'll basically follow those docs to create the two instances.
Let me know if you have questions.
