    • All configuration is done on Active firewall and replicated to Standby [configuration of MGMT interface may be an exception to this]
    • Physical and logical monitoring are different things.
    • Logical monitoring requires three IP addresses in the same network per interface, one shared and one per firewall. It allows you to use the reachability of something to determine which firewall is to be Active.
    • Physical monitoring simply checks up/down state of interface to determine which firewall is to be Active.
