Dual-WAN Configurations Dual-WAN Configurations
The MX-series router is a dual-WAN device, meaning it has two interfaces capable of providing
Internet access by default -- its WAN Ethernet port and the plug-in cellular modem -- though
additional LAN ports may even be reconfigured for supplemental Internet access. Active WAN
connections can provide both failover and load balancing per user-defined parameters
Failover Failover
By default, this allows the plug-in modem to serve as a secondary (backup) WAN that becomes
the active connection once the Ethernet WAN port is detected as offline. The router then
monitors the offline connection to see when it comes back online, which prompts the backup
interface to once again become inactive.
Each interface has a Metric Metric value associated with its IPv4 configuration. The example on this
page is associated with the WAN interface, which will take priority over all other interfaces by
default (as seen by its Metric value of "1").
Connectivity Monitoring Connectivity Monitoring

Both tests are set via the default group config in Accelerated View -- it is not built into the firmware.
Devices that have not synced with AView will not have these tests enabled by default.
To properly trigger a failover (or failback) scenario, test parameters must be defined to monitor
the primary connection. Both a Ping and HTTP test come built into the MX's WAN port
configuration by default. After 4 failed attempts, the secondary connection will take over
Internet access for the router. Similarly, the monitoring tests trigger the restoration of the
primary WAN connection when they detect that the interface with a higher metric has come
back up.
