  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

 

and the 

 

sections. If you have completed setup 

procedures in those sections, continue to the 

 to complete 

configuration.
