Port forwarding unaccesible when GW down

  • I have a behavior with 2.1 ; 2.1.1; 2.1.2

    As soon as default GW unavailable all forwarding ports became unavailable

    we have a fail-over installation.

    port forwarding defined as:

    CARP EXT IP:45000 -> LAN HOST IP:22
    NAT reflection: disable
    Filter rule association: Pass
    no restriction per inbound IP address.

    fiber connection became unstable and it 100% correlation between def gateway inaccessible and  port forwarding stop working when GW resumed.

    solution: simple reboot it , and it became operational again
