As I said named doesn't get the answers it needs.   If you ask a
recursive server non-recursive queries it will refer you to the
best set of nameserve it knows about.

When you have a "transparent" intercepting DNS recursive server
named just gets referrals for any question that it doesn't have a
cached answer for.

The intercepting server is expecting to see queries with "rd=1".
Named makes queries with "rd=0".
