Configure the Failover Multi-WAN Method

Before You Begin

Multi-WAN is not supported on the Firebox T10, or XTM 2 Series devices without the Pro upgrade. Multi-WAN is supported on Firebox T15 devices with Fireware v12.3 or higher. Although multi-WAN is not supported in certain cases, modem failover is supported for the Firebox T10 and T15. This is true even after an upgrade to Fireware v12.1 or higher, which converts modems to external interfaces. For more information, see Configure Modem Failover.
