Configuring Content Filtering

Content filtering blocks or allows HTTP access to websites containing specific keywords or domains. It controls access to certain Internet sites based on analysis of its content (domain), rather than its source or other criteria. It is most widely used on the Internet to filter web access.

Use the Content Filtering page to define the type of content filtering, configure the content filtering rules, export the content filtering rules to your local PC, and import the content filtering rules from a file.

To configure the content filtering settings:

  1. Click Security > Content Filtering. The Content Filtering page opens.
  2. Specify the type of filtering:
    • Blacklist: Select this option to block HTTP access to websites in the blacklist and allow HTTP access for other websites.
    • Whitelist: Select this option to allow HTTP access to websites in the whitelist and block HTTP access for other websites.
  3. To add a content filtering rule, enter the following information:
    • URL/Keyword: Enter the domain name or a keyword of a website that you want to permit or block. If you enter a keyword, HTTP access to a website that contains this keyword can be blocked or allowed.
    • File Type: Choose the type of files that you want to permit or block.
  4. Click Add.
  5. To delete a content filtering rule, select it and click Delete.
  6. To export the content filtering rules to your local PC, select the content filtering rules that you want to export and click Export.
  7. In the Import Content Filtering Rules area, you can import a mass of content filtering rules from your local PC. Click Browse to locate and select the file, and then click Import.
