Scenario B: HA Pair in NAT/Route Mode
For network installations with two SonicWALL NSA 240
appliances configured as a stateful synchronized pair for
redundant high availability networking.
In this scenario, one SonicWALL NSA 240 operates as the
primary gateway device and the other SonicWALL NSA 240 is
in passive mode. All network connection information is
synchronized between the two devices so that the backup
appliance can seamlessly switch to active mode without
dropping any connections if the primary device loses
connectivity.
To set up this scenario, complete the steps in the following
section. If you have completed setup procedures in those
sections, continue to the Additional Deployment Configuration -
page 47 to complete configuration.
