Data Flood Protection

To configure UDP Flood Protection

  1. Navigate to Network > Firewall > Flood Protection and select the UDP tab.

  2. In the UDP FLOOD PROTECTION section, select Enable UDP Flood Protection.

    This option must be enabled to activate the other UDP Flood Protection options.

  3. Set the UDP Flood Attack Threshold. When the number of UDP packets per second sent to a host, range, or subnet exceed this value, UDP Flood Protection is triggered. The minimum value is 50; the maximum is 1,000,000, and the default value is 1000.
  4. Configure the UDP Flood Attack Protected Destination List. Select Any to apply the Attack Threshold to the sum of UDP packets passing through the firewall.
  5. Click Accept.

Due to the nature of the large UDP packets used for voice and video, traffic for some collaboration products, such as Microsoft Teams, Zoom, and so forth, might be considered a UDP flood and could be dropped after configuring UDP flood protection. If you experience this, exclude traffic for those applications by following the steps in Microsoft Teams Randomly Dropping (Video Conferencing Applications)
