    Hello Fluvio,

    I had this problem in ZeroShell 3.5.0.

    Architecture:
    We have 3 gateways in the load balancer configuration.
    and also one specific route for a VPN connexion (defined in the route part)

    Default Gateway : weight 1 (reserved for our intranet website and email traffic)
    VDSL#1 : weight 60 (surf on Internet)
    VDSL#2 : weight 2 (surf on Internet)

    VDSL#2 goes down this morning.
    Traffic was automatically routed to our default gateway.

    At 14h39, i tried to force a check of VDS#2 by uncheck and re-check the VDSL#2, our network becomes unreachable from external.

    Solution: Goto Net balancer: Uncheck “Default Gateway” + save and check + save “Default Gateway”

    here is the log of our load balancer:

    Do you need more information or do you know what happened ?

    Best regards,
