Web filtering URL filtering 6 Add a URL category to a blocking list You can add a URL category to a blocking list to block access to all URLs falling into that category. 1 Go to Policy | Rule Sets. 2 On the rule sets tree, select the rule set that contains rules for URL filtering. The rules appear on the settings pane. 3 Find the rule that uses a category blocking list, for example, Block URLs whose category is in Category BlockList, and click on the list name. Note: A yellow triangle by the list name indicates that this list is empty and you need to fill the entries. The Edit List (Category) window opens. 4 Expand the group folder with the category you want block, for example, Purchasing, and select the category, for example, Online Shopping. Note: To add multiple categories at once, select multiple categories or one or multiple group folders. 5 Click OK. The window closes and the category appears on the blocking list. 6 Click Save Changes. For more information on how to maintain lists, see List maintenance. Extended Lists for blocking URLs per category You can maintain Extended Lists of URLs that you have assigned to categories yourself. These lists can be included when the URL filter module retrieves category information. This section tells you how to add and edit an Extended list.
