Give it a full access to the Internet and a root zone of type hint,
with the root name servers in it (it is done by default in BIND
distribution).

options {
   ...
   forwarders { X.Y.Z.T; }; // IP address of the "external named server"
   forward-only;
   ...
};

But, with BIND 9, views can be a better way, with only one nameserver.
