        Hi there,

        Let me ask you if some of you have troubles with a scenario like
this:

                - 01 internal DNS server (W2K).
                - 01 external DNS server (Public DNS).
                - 01 ISA Server between them.

        I setup TCP and UDP port 53 to allow traffic between the two DNS
servers. I also made a IP Packet Filtering for those protocols.

        The problem is something like the internal DNS can not forward
to external DNS to resolve external names.

        Any helps will be welcome.

        Regards,
        Ricardo Paranhos
