Selecting a Deployment Scenario | 28
Scenario C: L2 Bridge Mode
For network installations where the Dell SonicWALL NSA
E8500 is running in tandem with an existing network gateway.
In this scenario, the original gateway is maintained. The NSA
E8500 is integrated seamlessly into the existing network,
providing the benefits of deep packet inspection and
comprehensive security services on all network traffic.
L2 Bridge Mode employs a secure learning bridge architecture,
enabling it to pass and inspect traffic types that cannot be
handled by many other methods of transparent security
appliance integration. Using L2 Bridge Mode, a Dell SonicWALL
security appliance can be non-disruptively added to any
Ethernet network to provide in-line deep-packet inspection for
IPv4 TCP and UDP traffic.
To set up this scenario, follow the steps covered in:
• Initial Setup - page 29
• Configuring L2 Bridge Mode - page 43
• Additional Deployment Configuration - page 46
Note: Be sure to follow the steps in the Initial Setup section,
on page 29 before completing L2 Bridge Mode setup.
