    What settings and where do I place (order) loopback rules for firewall?

    Looked at standard loopback rule:
    UDP/TCP Out (local)Any Port (remote) 127.0.0.1/255.0.0.0 Any Port.
    Must work with other security software.

    Loopback rule? UDP/TCP ( both directions ) local (any port) remote 127.0.0.1 (any port) any application

    Set to block.

    The standard loopback rule comes from BlitzenZeus default replacement ruleset for Kerio 2
    firewall. Rules need to be placed in right order to be effective.
    (UDP/TCP Out (local)Any Port (remote) 127.0.0.1/255.0.0.0 Any Port)

    When I ping localhost all packets are sent and received with 0% loss.
    UDP/TCP ( both directions ) local (any port) remote 127.0.0.1 (any port) any application
    Set to Deny.
