This article explains what a Block Page is and how to add a Block Page in the DNSFilter app.

A Block Page is what users see when they attempt to visit a domain that is not allowed by the policy assigned to their network or Roaming Client. 

From the DNSFilter dashboard you can customize a Block Page’s appearance, behavior, bypass passwords, and notifications. 

See the Block Page administrator guide for troubleshooting and email notification details. 

There are two types of Block Pages: hosted and external.

Hosted Block Pages are customizable and present the user a page with organizational information and options to enter a bypass password or notify the administrator via embedded form. 

Hosted Block Pages can be displayed in several languages, depending on the browser language of the end-user device. We currently support English, Spanish, Portuguese, Turkish, Ukrainian, Italian, Russian, French, Czech, German, and Hebrew.

External Block Pages send the user a 302 redirect to a set location. This allows you to completely customize the Block Page appearance. The External Block Page URL contains the IP address, blocked domain, filtering policy, and categories as an identifier.

This can be a local-only resource–e.g. http://office.local/block.html –or a public resource–e.g. http://validdomain.com/block.html

Below is a video demonstration of creating a Block Page:

To make sure this feature works with websites over HTTPS, install our SSL Certificate. If the SSL Certificate is not installed, HTTPS sites will return error pages but will still be blocked by the Filtering Policy.
