Setting 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.
DNS Server The IP address of the DNS server.
