DNS trouble w/ triple-homed box


I have a triple-homed box with 2 interfaces world accessible and one on an internal/private netowrk that has a DNS server. I'm not sure how to setup the resolve.conf file to lookup anthing that's on the private network.

Or is it possible to have my DNS server forward/redirect a request for a private network address to the private network DNS server eg.

client want -> asks DNS server
DNS server says "why don't you ask"
client asks which then resolves the name.

I suppose you're talking of BIND...
in your named.conf, you should have entries like:
zone {
   type master;
   file myzone.db;
With Bind, you can set up forwarders as with any other DNS server (for non local domains), but also specific forwarders for specific zones:
zone {
   type forward;
   forwarders {;};
Thus you say that every single query for * must be forwarded first to, and secondly to (which should be the DNS servers responsible for this zone).

I think that's pretty much what you're after... the above cannot be done with a Win200x server, but Bind shouldn't be the only one to manage this.
If you have a win server (and dared posting on this forum, arglll!!!!), then you can only set this up for subdomains (ie can have a specific forwarder for, but not for

Hope this helps
