Video: Demonstration of Squid Overriding Firewall Rules in pfSense

One phenomenon I initially didn’t understand is the fact that once Squid is enabled in an interface, it overrides any firewall rules you might have for ports that are controlled by Squid (80 and, if you enable the SSL proxy, 443). This is important to understand if you already have firewall rules in place. This video demonstrates this in practice.
