Updated
This article applies only to the Smoothwall On-Premise Appliance, not to our Cloud products.

Content Modification allows you to grant access to specific websites while blocking certain content types on the pages your users visit. Create a custom Content Modification only if existing Content Modifications don’t suit your needs and you know the content to block.

Create a custom Content Modification

  1. Go to Guardian > Content modifications > Policy Wizard.
  2. Expand the Action section.
  3. Select Create a new content modification. The page opens in a new tab.
  4. Enter a Name and optional comment.
  5. If you have a multi-tenant setup, you’ll see the Tenant field:
    • Select All to apply the Content Modification when used in a Content Modification Policy to all tenants.
    • Select a tenant to have the Content Modification when used in a Content Modification Policy only apply to that tenant.
  6. Enter any HTTP Headers to the Request headers to override field in a comma-separated list.
    Select Save.
  7. Close the tab and return to your original tab. You can now use this Content Modification in a Content Modification Policy.
