Description

WAN Failure Detection Method

Select a failure detection method from the drop-down list. DNS queries or pings are sent through the WAN interface that is being monitored. The retry interval and number of failover attempts determine how quickly the UTM switches from the primary link to the backup link in case the primary link fails, or when the primary link comes back up, switches back from the backup link to the primary link.

WAN DNS

DNS queries are sent to the DNS server that is configured in the Domain Name

 

Server (DNS) Servers section of the WAN ISP screen (see Manually Configure the

 

Internet Connection on page 75).

 

 

Custom DNS

DNS queries are sent to the specified DNS server.
