24 Configuring Multi-WAN
Multi-WAN is used for managing WAN interfaces on the router, for example, 3G
interfaces to ensure high-availability. You can customise Multi-WAN for various needs,
but its main use is to ensure WAN connectivity and provide a failover system in the
event of failure or poor coverage.
Multi-WAN periodically does a health check on the interface. A health check comprises of
a configurable combination of the following:
ï‚· interface state
ï‚· pings to an ICMP target
ï‚· signal level checks using signal threshold, RSCP threshold and ECIO threshold
option values
A fail for any of the above health checks, results in a fail. After a configurable number of
health check failures, Multi-WAN will move to the next highest priority interface. Multi-
WAN will optionally stop the failed interface and start the new interface, if required.
In some circumstances, particulary in mobile environments, it is desirable for a primary
interface to be used whenever possible. In this instance Multi-WAN will perform a health
check on the primary interface after a configurable period. If the health checks pass for
the configured number of recovery health checks then the primary will be used.
