Scenario C: L2 Bridge Mode

For network installations where the SonicWALL NSA E6500 is running in tandem with an existing network gateway.

In this scenario, the original gateway is maintained. The SonicWALL NSA E6500 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 SonicWALL security appliance can be non-disruptively added to any Ethernet network to provide in-line deep-packet inspection for all traversing IPv4 TCP and UDP traffic. L2 Bridge Mode can pass all traffic types, including IEEE 802.1q VLANs, Spanning Tree Protocol, multicast, broadcast and IPv6.

To set up this scenario, follow the steps covered in the Initial Setup and the Configuring L2 Bridge Mode sections. If you have completed setup procedures in those sections, continue to the Additional Deployment Configuration section, on page 41 to complete configuration.
