failure methods:
DNS lookup using ISP DNS Servers. DNS queries are sent to the DNS server
configured on the WAN ISP screens (see <pdf>“Configuring the Internet
Connections” on page 2-17).
DNS lookup using this DNS Server. Enter a public DNS server. DNS queries are
sent to this server through the WAN interface being monitored.
Ping to this IP addresses. Enter a public IP address that will not reject the Ping
request and will not consider Ping traffic to be abusive. Queries are sent to this server
through the WAN interface being monitored.
5. Enter a Retry Interval in seconds. The DNS query or Ping is sent periodically after
every test period. The default test period is 30 seconds.
6. Enter the Failover after count. The WAN interface is considered down after the
configured number of queries have failed to elicit a reply. The rollover link is brought up
after this. The Failover default is 4 failures.

30-second minimum test period for a minimum of 4 tests).
