Understanding DNS Filtering
How to Set Up DNS Filtering
- Open Networks from the Management Platform and navigate to the network on which you'd like to configure DNS filtering. Select the three-dotted icon on the right side, then select DNS Filtering.
2. Fill in the following information:
- Enable DNS Filtering.
- URL Blacklist Categories: Block access to websites by content category (select none, one or more).
- Whitelisted/Blacklisted URLs: Manually enter one or more specific URL(s) you'd like to make sure stay unblocked/blocked, or upload a .CSV file containing the addresses. Make sure that the .CSV file contains only one column, and that every cell contains one URL (as shown in the attached example). The file must contain no more than 1000 addresses. Each address must follow the form domain.com (that is, without www/HTTP/HTTPs prefixes).
Please note that when you block a domain, this will also block any related sub-domains.
3. Select Apply.
4. A successful message appears. Once it has been closed the new settings will be applied the next time a user connects to the network.
- Ensure you have a clear understanding of what needs to be blocked or allowed according to your organization's policy.
- Test the DNS filtering settings to confirm they are working as expected.
