Setting Description
Ping IP Address The IP address of the interface that should receive the ping request. The interface
should not reject the ping request and should not consider ping traffic to be abusive.
Note:
Pings are sent through the WAN interface that is being monitored. The retry
interval and number of failover attempts determine how quickly the VPN firewall
switches from the primary link to the backup link if the primary link fails, or when the
primary link comes back up, switches back from the backup link to the primary link.
Retry Interval is The retry interval in seconds. A ping is sent after every retry interval. The default retry
interval is 30 seconds.
Failover after The number of failover attempts. The primary WAN interface is considered down after
the specified number of queries have failed to elicit a reply. The backup interface is
brought up after this situation has occurred. The failover default is 4 failures.
