Multi-Bridge Mode Parent topic

Multi-Bridge mode is variation of Transparent Bridge mode where Deep Discovery Web Inspector is equipped with two bypass cards and connects to the Internet through two WAN lines. The appliance acts as a layer 2 bridge between network devices (core switches and routers) and is transparent on the network.
Deep Discovery Web Inspector performs security scans on HTTP/HTTPS traffic that passes through the ingress and egress ports and takes action if there is a traffic match according to configured policies. The appliance can bypass scanning and let the traffic pass straight through the appliance, block the traffic without scanning, or scan the traffic and then either block or monitor the traffic, depending on actions configured in policies.
Multi-Bridge mode is suitable when you want to use Deep Discovery Web Inspector as an inline device and there are two network paths to the Internet and two separated internal networks that you want to monitor and secure.
