You would like to block users behind your EnGenius router from accessing
Facebook.  You will notice that setting the parental control on the
router to block the URL www.facebook .com or keyword
“facebook” works when accessing Facebook via the URL
http://www.facebook.com but not when
accessing using the URL https://www.facebook.com.

 

Most, if not all home routers including all EnGenius routers, cannot block
HTTPS secured websites. This is because HTTPS encrypts the URL name so it
is not recognized by the router.
