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.
