interfaces. This field is dimmed if the LAN Failover interface is selected in the Interface
drop-down list.

Standby IP—Specifies the IP address used by the secondary unit to communicate with the
primary unit. This field is dimmed if the LAN Failover interface or Use Named option is

Enable HTTP replication—Selecting this check box enables Stateful Failover to copy active
HTTP sessions to the standby firewall. If you do not allow HTTP replication, then HTTP
