Periodic latency checking packets are sent to the WAN connection. Latency will then be determined by the response time of the second and third hops. The traffic matching this rule will be routed through the healthy WAN connection with the lowest latency.
On current firmware, the default “Auto” rule uses the lowest latency algorithm.
Common use case
Useful for time-sensitive applications such as online gaming.
useful when using multiple cellular WAN connections.
