Manage Secondary IPv4 WAN Addresses

The following sections provide information about managing secondary IPv4 WAN addresses:
• Secondary IPv4 WAN Addresses
• Add a Secondary WAN Address to a WAN IPv4 Interface
Description
Select a failure detection method:
• WAN DNS. DNS queries are sent to the WAN DNS server that you configured for
the WAN interface (see
Settings on page 30).
• Custom DNS. DNS queries are sent to a DNS server that you must specify in the
DNS Server field.
• Ping. Pings are sent to a public IP address that you must specify in the IP
Address field.
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.
The IP address of the DNS server.
The IP address of the interface that must receive the ping request. The interface must
not reject the ping request and must not consider ping traffic to be abusive.
The retry interval in seconds. The DNS query or ping is sent after every retry interval.
The default retry interval is 30 seconds.
The number of failover attempts. The primary WAN interface is considered down after
the specified number of queries has failed to elicit a reply. The backup interface is
brought up after this situation occurs. The failover default is 4 failures.
