Enabling/Disabling Bypass Mode Parent topic

For Bridge Mode deployments, you can enable the Deep Discovery Web Inspector appliance for bypass mode, which allows traffic to bypass inspection as it traverses the appliance. Bypass mode can be used as a diagnostic tool and a fail-over mechanism to ensure that traffic continues flowing through the Deep Discovery Web Inspector appliance during software failure or system upgrade. After issues are corrected or upgrade completed, you can disable bypass mode so that traffic will again be inspected by Deep Discovery Web Inspector.
Bypass mode protects from unexpected events that block web traffic, including the following:
  • Scanner is unavailable
  • OS kernel crashes
  • System powers off
CAUTION
CAUTION
Do not change the bypass mode setting if you are unsure of the impact to Deep Discovery Web Inspector functionality. Contact Trend Micro Technical Support for assistance if needed.

Procedure

  1. Go to Administration → System Maintenance → Bypass Mode.
  2. Perform the appropriate action:
    • To enable bypass mode and allow traffic to pass through the device without inspection, turn the option On.
    • To disable bypass mode and allow traffic to be inspected, turn the option Off.
      If set to Off or the device is down, traffic will pass through the device without inspection.
    After you change the bypass status, traffic through the Deep Discovery Web Inspector appliance is temporarily disrupted for a maximum of about 5 seconds. As most browsers and applications have TCP retransmission mechanisms, impact to the end user is limited.
