Failure Detection Method
Note: This is the failure detection method for IPv4 interfaces. For information about failure detection for
IPfv6 interfaces, see Configure the Failure Detection Method for IPv6 Interfaces on page 70.
Failure Detection Method Select a failure detection method from the drop-down list:
• W
AN DNS. DNS queries are sent to the DNS server that is configured in
the Domain Name Server (DNS) Servers section of the W
AN ISP screen
(see Manually Configure an IPv4 Internet Connection on page 34).
• Custom DNS. DNS queries are sent to a DNS server that you need to
specify in the DNS Server fields.
• Ping. Pings are sent to a server with a public IP address that you need to
specify in the IP
Address fields.
The server should not reject the ping
request and should not consider ping traffic to be abusive.
Note: 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 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.
DNS Server
The IP address of the DNS server
.
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
Retry Interval is The retry interval in seconds. The DNS query or 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.
