Advanced Deployment Modes

Most IDP sensors are configured in passive sniffer or transparent mode. However, the IDP 75, 250, and 800 sensors can also be configured in bridge, router, or proxy-ARP mode.

Bridge Mode

Figure 21 shows a sensor that is configured in bridge mode. Table 14 lists the advantages and disadvantages of bridge mode.
