How to block facebook

[gazoder]

Hi all,
i have pfsense box 1.2.3 and wanna block facebook on port 443. I have blocked it on port 80 using transperent proxy, blocked it with creating an alias on port 443, but 3-4 pc's have to have access to facebook. So how i can block it on defined range of ip's?
