DELL NSAE6500 User Manual

Selecting a Deployment Scenario   |   

28

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

In this scenario, the original gateway is maintained. The 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 Dell 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

and

, on page 42. If you 

have completed setup procedures in those sections, continue to
