Hi,

I haven't tried this but, if you are *not* already using the DNS Forwarding
system in pfSense:

You could enable and configure the DNS Forwarding system to redirect all
Facebook.com DNS requests to a bad IP (or your Intranet IP). Then, create a
LAN rule (on a schedule) that redirects all outgoing DNS port traffic to
the pfSense IP address.

During the active schedule period, this would redirect all external DNS
queries to pfSense's DNS Forwarder system. Thus, users attempting to access
Facebook.com et al would get forwarded to nowhere (or your Intranet, etc).

There may be a better way, but I will leave that to others :)

Regards,
Kyle Spencer
