Selecting a Deployment Scenario
Scenario B: State Sync Pair in NAT/Route Mode
For network installations with two SonicWALL NSA E-Series
appliances configured as a stateful synchronized pair for
redundant high-availability networking.
In this scenario, one SonicWALL NSA E6500 operates as the
primary gateway device and the other SonicWALL NSA E6500
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, follow the steps covered in the
Initial
Setup
and the
Configuring a State Sync Pair in NAT/Route
Mode
- page 32
sections. If you have completed setup
procedures in those sections, continue to the
Additional
Deployment Configuration
section, on page 41
to complete
configuration.
