@ElectroPulse:
So far HTTP blocking has been working wonderfully… However, HTTPS blocking hasn't been. I've been reading about and working on this all week, and have yet to be able to block secure websites (due to the version of Squid I'm running).
pfSense version: 2.0.3
Squid Version: 2.7.9
SquidGuard Version: 1.4_4
By design, squid can not intercept HTTPS traffic. So if you want to block traffic to this site, you have to add firewall rules to block traffic on port 443 to the websites you want to block.
