SonicOS 5.8.1 Administrator Guide
• Wire/Tap Mode - Wire Mode is a deployment option where the SonicWALL appliance can
be deployed as a "Bump in the Wire." It provides a least-intrusive way to deploy the
appliance in a network. Wire Mode is very well suited for deploying behind a pre-existing
Stateful Packet Inspection (SPI) Firewall.
Wire Mode is a simplified form of Layer 2 Bridge Mode.
A Wire Mode interface does not
take any IP address and it is typically configured as a bridge between a pair of interfaces.
None of the packets received on a Wire Mode interface are destined to the firewall, but are
only bridged to the other interface.
Wire Mode operates in any one these 4 different modes:
–
Bypass Mode - Bypass Mode can be configured between a pair of interfaces. All traffic
received is bridged to the paired interface. There is no SPI or Deep Packet Inspection
(DPI) processing of traffic in this mode. There is no Application Visibility or Control in
Bypass Mode.
–
Inspect Mode - Inspect Mode can be configured between a pair of interfaces. All traffic
received is bridged to the paired interface; in addition, the firewall does SPI and DPI
processing of traffic. There is full Application Visibility, but no Application Control in
Inspect Mode.
–
Secure Mode - Secure Mode can be configured between a pair of interfaces. All traffic
received is fully processed by the firewall. There is full Application Visibility and Control
in Secure Mode.
–
Tap Mode - Tap Mode can be configured for a single interface. All traffic received is
never sent out of the firewall, but the firewall performs full SPI and DPI processing.
There is full Application Visibility, but no Application Control in Tap Mode. Typically, a
mirror port is set up on the switch to mirror the network traffic to the firewall.
Wire Mode is supported on the followin
