Configuring Custom IP List

  • Last updated on

Overview

Use this section to upload/download a Custom IP List text file to the Barracuda Web Application Firewall.

To add more IP addresses to the current list, upload a new file that contains both the existing and the newly added IP addresses list. Once you upload the new file, the current list is overwritten with the new list. It is recommended to save a local copy of this file because you cannot view the contents of the file after you upload it.

This feature is  supported ONLY on Network Layer IP Reputation.

  • Before you upload/download a Custom IP List text file, set Advanced Settings to Yes on the ADVANCED > System Configuration page .
  • Ensure that every IP address in the text file is provided in a new line.
  • CIDR notation is not supported.
