20 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.
