pfSense (2.3.2-RELEASE-p1) and SquidGuard (1.14_4)

I've been spending so much time to block a custom URL which isn't part of the blacklist. Here is what needs to be done.

1. Create your Target categories (e.g.: iflix | iflix.com) and save it. With emphasis on "save" or whatever makes the change stick!
2. Go to Common ACL > Target Rules List and select the new category created - either allow or deny it. Denying the category for testing is easy. :)
3. Go to General settings and click Apply the Save at the bottom of the page.

Test your new category if it gets blocked. You can also verify by going to Log > Blocked and see if the domain/URL gets blocked.
