Using my modem/routers inbuilt firewall URL Filter I have managed to block/restrict my kids (mainly my eldest, a determined 15yo daughter) access to Facebook reasonably successfully over the past year or so (fighting the constant battle with proxies) . . . . until my eldest (bless her little hacker's heart) discovered the joys of HTTPS! So while the URL filter *facebook* successfully denies access to http://www.facebook.com, it does not deny access to https://www.facebook.com. So any ideas on how to filter this encrypted traffic without doing a general port 443 block (https). Failing that any ideas on how to lock down general https:// traffic at the modem would be gratefully appreciated! (I don't want to go to a separate blocking program if I can avoid it).
