You can retrieve an external dynamic list from the web server to view its entries and be sure that your configuration always has the latest information without requiring manual updates. It's a good idea to look at your external dynamic list (EDL) entries to assess the information present in these lists. Viewing external dynamic list entries gives you insights into the threat intelligence being used for security policy enforcement, and helps you maintain an up to date and robust security posture.

When you Configure Your Environment to Access an External Dynamic List, you can configure the firewall to retrieve the list from the web server on an hourly (default) five minute, daily, weekly, or monthly basis. If you have added or deleted IP addresses from the list and need to trigger an immediate refresh, use the following process to fetch the updated list.
