That would work, however you really shouldn't run anything else on your
firewall.
 You can have an internal DNS server that's authoritative to your internal
network, that also does "forwarding" against external DNS servers without
having to worry about authorized or unauthorized zone transfers.
 If your DNS server is set up correctly, zone transfers will be denied if
not configured anyway (Settings within MS DNS, I don't know about BIND).
Also, if doing NAT, no one in the "real world" will be able to touch your
DNS server unless your DNS server initiated the session anyway.

The simple answer is to set up a cache only DNS on the Firewall box and
forward all internal DNS queries to it.  Then set up the rules
to allow DNS.  That's what I've done and I have no DNS resolve problem plus
I don't have DNS leakage problem or authorized zone transfer issues.
