4.1.2 Normal Active Inline
This setting allows traffic to flow between N1 and N2 while heartbeats continue to flow between A1 and
A2. Loss of heartbeats will direct traffic from N1 to A1 and N2 to A2. This mode may be used to make
sure the heartbeat is flowing through the appliance, while network traffic is not flowing through the
appliance.
