The traditional method has been to run two different instances of the zone,
with the external being a subset of the internal. Unfortunately, this usually
means double maintenance for the external names.

The "views" mechanism described in the _DNS_and_BIND_ book would permit
"conditional forwarding" to another server if a name wasn't found locally. If
and when "views" are incorporated into BIND 9, then this should enable the
kind of "split" you describe, which would be more maintainable than the
traditional method.
