SonicWALL NSA 5000/4500/3500 Getting Started Guide Page 17
Scenario A: NAT/Route Mode Gateway
For new network installations or installations where the
SonicWALL NSA Series is replacing the existing network
gateway.
In this scenario, the SonicWALL NSA Series is configured in
NAT/Route mode to operate as a single network gateway. Two
Internet sources may be routed through the SonicWALL
appliance for load balancing and failover purposes. Because
only a single SonicWALL appliance is deployed, the added
benefits of high availability with a stateful synchronized pair are
not available.
To set up this scenario, follow the steps covered in the Initial
Setup section. If you have completed setup procedures in that
section, continue to the Additional Deployment Configuration
section, on page 37 to complete configuration.
