Dual WAN- Failover/Loadbalancing error - arpresolve:can't allocate llinfo for ..

[baje]

Hi,

LAN - igb0
WAN1 - igb5
WAN2 - igb4

In setting up opnsense in Failover/Loadbalancing mode, when I disconnect WAN2 everything works fine, but when I disconnect WAN1, I get the following error:

arpresolve: can't allocate llinfo for 192.168.1.1 on igb5

I followed the documentation under sections ....  » System » Gateway groups / Multi WAN

Any assistance would be greatly appreciated.
