      Yet another reason to go with a large-authoritative-core approach,
      instead of stringing stuff together with recursive arrangements.
      Would you rather build an enterprise-strength DNS infrastructure

      OK, I'll get off my infrastructure architect soapbox now...<br>

              See "allow-update-forwarding" in the ARM. Obviously you
              will lose source IP / TSIG key info, so will need to
              perform access checks at the forwarding server, and allow
              everything you need at the target server from the
              source/key of the forwarder.<br>
