Configuring the WAN Mode (Required for Dual-WAN Port Models Only)

On dual-WAN port models only, the dual-WAN ports of the UTM can be configured on a mutually exclusive basis for either auto-rollover (for increased system reliability) or load balancing (for maximum bandwidth efficiency), or one port can be disabled.

•Auto-Rollover Mode. The selected WAN interface is defined as the primary link and the other interface is defined as the rollover link. As long as the primary link is up, all traffic is sent over the primary link. When the primary link goes down, the rollover link is brought up to send the traffic. When the primary link comes back up, traffic automatically rolls back to the original primary link.
