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.
