Block Page Setup

The block page is displayed when a user is trying to access a website blocked by the filtering rules. SafeDNS provides instruments to customize the block page. For example, you can add your logo and contact details on the block page, and an explanation why the website site is blocked.

Creating custom block page

To create a custom block page, do the following:

  1. Log in to SafeDNS Dashboard.
  2. Navigate to Settings > Advanced and scroll down to the block page section.
  3. Click "Add new".
