3. Click `Web access protection`. Expand `URL list management` and click `Edit` next to `Address list`
4. Select `List of allowed addresses` and click `Edit`
5. Click `Add` in the `Edit list` window. Paste `*sonorancms.com*` in the respective field, click `OK` → `OK` to save your changes, and exit the Advanced setup window.
   * If using CAD, also add `*.sonorancad.com*`
