I am allowing UPD and TCP 53 from the my DNS It sounds like the forwarders stuff isn't done correctly- do the internal servers generate traffic destined to the external ones? > servers to the ISP's servers.

Is this some start of authority If you get an immediate response, then either you're not forwarding the query or the server you're querying isn't forwarding its queries. Sniff the internal nameserver's interface and see if it's asking the external one, that will narrow the problem down to either a configuration error or a resolver issue.
