I have a Balance One and two WANs (let’s call them WAN1 and WAN2). I basically want all traffic to use WAN2 first, but if WAN2 is getting congested to go ahead and use WAN1 as well.
I think my choice is either between Priority or Overflow:
**Priority: ** Traffic will be routed through the healthy WAN connection that has the highest priority.
Overflow: Traffic will be routed through the healthy WAN connection that has the highest priority and is not in full load. When this connection gets saturated, new sessions will be routed to the next healthy WAN connection that is not in full load.
It sounds like under Priority, once WAN2 gets saturated, WAN1 would remain un-used. But under Overflow, WAN1 would be used after WAN2 is full.
Do I have that right? If so, it sounds like I want Overflow.
