Selective forwarding is actually one of the major improvements in BIND
8.2 over previous versions.  But ISTM that you don't really need it for
your configuration.  Set your internal name server to be authoritative
for the internal domain(s) and reverse DNS lookups.  Forward [only] to
... well, now, I am puzzled.  At one point you say there is no
connection to the Internet, and at another you say that you can forward
to the Internet.  Which is it?  ;-)  I suspect you have a firewall with
that DMZ.  You can run your external name server on the firewall bastion
host, which will also allow DNS forwarding through it.

As always, the O'Reilly book "DNS and BIND" by Albitz & Liu is the
definitive reference to anything pre-8.2, and the "type forward" zones
and other updates in 8.2.* are fairly well documented.  If you are using
8.2.2, please make sure to get a current patch level [P5?].
