    Question Internet Network to Internal Network - issue

    Hi, We are seeing on our untangle box between one Internal Network 192.168.6.x to Internal Network 192.168.2.x these - "ET POLICY DNS Update From External net". The .6 network is trying to reach a dns server on the .2 range.

    How do we exclude these?

    Bypass rules are your friend, Untangle isn't designed for scanning internal traffic.

    Config -> Network -> Bypass

    Source Interface is Any Non-WAN
    Destination Interface is Any Non-WAN
    Destination Port 53

    Action Bypass

    That rule will exempt any DNS request moving from any internal network, to any internal network from any Untangle filtration.

    Honestly, You should be considering bypassing everything between LANs at this point in general, but for now you've expressed a concern with DNS specifically.
