That's quite easy: Block the IPs that belong to Facebook, for example 185.60.216.35 and 157.240.20.36. Instead of blocking them, you could also redirect them to your internal web server which displays a nice "Back to work!" motivational image. ;-) However, this will only work from within your LAN. If the users are able to access a WLAN with their smartphones, or use their smartphones to connect to the Internet, the main problem - probably any "doing Facebook at work" - cannot be solved that easily. But you can get your "work-related resources" to not being able to access Facebook. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
