Yeah, I have something fairly similar. Is this all a caching-forwarder
needs to know? or should it know about the private network it is
connected to?

So, if I removed the root zone hints from my master nameserver leaving
only my network and host names, but still had the root zones on the
caching-forwarder, it should still work?

The part I am trying to work out is how or what happens if a client
resolver requests something from the slave nameserver, but does not
have the information, not does the master.. how does it go to the
caching-forwarder nameserver? really just trying to minimise any
potential dns poisoning, etc.
