    Default How do I unblock DNS on DMZ

    Hi,

    We have enabled protocol control to block DNS so the kids at our school cant go around our OpenDNS web blocker.
    Now our web server can't access its DNS server. I tried to change the DNS address on the web server to the untangle public address but that doesn't work.
    How would I allow DNS access to our web server behind the DMZ?

    Thank you,

    Shawn

    Don't use protocol control. Use the packet filter to filter on destination port 53 udp and tcp.

    Protocol control is horribly ineffcient for something like this.
