  you'll have to excuse my ignorance.

the internal network will be a combination NAT and Real ip's.

so My internal DNS box is the primary server (hidden master) and it 
holds the authoritative info for my domain. The external box is then 
setup as a slave (external master?).
Is the term "slaves" the type of configuration? it is this term / 
configuration that I am unfamiliar with.

I can lookup the "howto" in dns & bind. Is "setting up slave servers" 
what it's called?
what is different about setting up a slave dns compared to a stand 
alone Primary Dns?

Thanks for you input.
