NOTE: Ticket T4362 says this is fixed

lots of issues with load balancing.

Load Balancing Issues

• Very different command structure from the Ubiquiti EdgeRouter EdgeOS and USG.
• set load-balancing wan
• Has a few problems. Basically broken in 1.4 rolling.
• Return from failover does not happen.
• Ping Target does not appear on eth1.
• Other troubles not yet understood.

Features

• If health ping targets are not specified, the nexthop router address will be dynamically configured based on dhcp for ping health.

References

• Files used
  • /var/run/load-balance/wlb.conf
  • /boot/rw/var/lib/dhcp/dhclient_eth0.leases
  • /var/lib/dhcp/dhclient_eth1.lease
  • Not sure health pings will bind to interfaces or they will take the default route.
• Operational Mode Commands (op-mode)
  • show dhcp client leases interface eth0
  • show wan-load-balance
  • restart wan-load-balance
