Hello;

Even though you have banned facebook on Endian Firewall, users can type https://facebook.com, that is https You can log in to facebook using strong>. So let me talk about how to eliminate this situation. In the etc/hosts file;

127.0. 0.1       facebook.com
127.0.0.1      www.facebook.com

. Another method is; It directly cuts the 443 port. However, this time users will not be able to login to banks or shopping sites . The choice is yours:)
