How to block downloading files and displaying images in PfSense?

Question

linux

I have assembled a small PfSense proxy server, and I would like to know how to properly set up blocking download files for example "exe" and block content like "alcohol"?

Answer 1

This is done through a proxy server, such as squid.
But in any case, this will only work for http, you can make it work with https, but this is extremely bad and difficult. Welcome to the world with the ubiquitous https.
