Hello everyone, this is my first post so sorry if you do not explain to me in the best way.

I have a router / firewall Draytek Vigor 3220 series, I did some locks from specific websites like Web Whats, Facebook, American, among others, the firewall in Firefox and Safari blocks all sites (using http or https), only in Chrome and In IE when using https the sites work by going through the firewall blockage not being blocked, I have a Windows Server 2012R AD server running our DNS server, and doing some tests I realized that when I use the public DNS of google 8.8.8.8 the lock works Correctly in Chrome and IE blocking the sites, I wanted to make the firewall work in all browsers using our DNS server but I have no idea what I can change for this to happen, if anyone knows what I can do thank you very much for the help.

Anyone can side step blocking if you allow connecting devices to use their own DNS.

Your client devices need to be set to use the same DNS as your router.
