SonicOS 7.1 System

Settings

To configure the WAN Failover for a SonicWall appliance

  1. Navigate to the NETWORK | System > Failover & LB page.

    Failover & Load Balancing Settings

  2. On the Settings tab, select Enable Failover & LB. This option must be enabled for you to access the Groups and Statistics tabs. If disabled, no options for failover and load balancing are available for configuration. This option is selected by default.
  3. Select Respond to Probes. When enabled, the appliance can reply to probe request packets that arrive on any of the appliance’s interfaces. This option is not selected by default. Enabling this option makes the Any TCP-SYN to Port option available.
  4. Select Any TCP-SYN to Port.
  • This option is only available when the Respond to Probes option is enabled. When selected, the appliance only responds to TCP probe request packets having the same packet destination address TCP port number as the configured value. The default TCP port number is 0.
  • This option is not selected by default.
  • Click Accept.
