It might be simpler than you are making it out to be. The default 
listen-on setting is to listen on all active interfaces and IP 
addresses. If you want your server to be an NS host for the world on 
the WAN interface, and a resolver for the LAN and for itself, you 
could simply remove "listen-on" from your options stanza.

If you want to exclude the WAN interface, that's a different matter, 
but not difficult; just list all your internal addresses in listen-on 
statements.
