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:
Code:
