Content Filtering

To perform SonicWall Content Filtering on HTTPS and SSL-based traffic using DPI-SSL

1. Navigate to POLICY | Security Services > Content Filter.
2. Ensure SonicWall CFS is selected for the Content Filter Type from the drop-down menu.

3. Scroll to the Global Settings section.

   

4. Select Enable Content Filtering Service.

5. Click Accept.

6. Navigate to the POLICY | DPI-SSL > Client SSL page.

7. Click General.

   

8. Select the Enable SSL Inspection checkbox.

9. Select the Content Filter checkbox.

10. Click Accept.

11. Navigate to a blocked site using the HTTPS protocol to verify that it is properly blocked.

    For content filtering over DPI-SSL, the first time HTTPS access is blocked results in a blank page being displayed. If the page is refreshed, the user sees the firewall block page.
