I've gone through the menus of the Internet Box portal and there is no feature for external "Domain Blocking" or Content Filtering. Looking in Parental Controls, there is no config setting for blocking domains manually.
For example, to block Facebook, there is no appropriate place to enter "facebook.com" at the router config portal. Is this possible with the Swisscom Internet Security? This software seems only for endpoint devices, not routers.
I am using the up-to-date firmware 10.00.44
