Restricting Web Pages

[tals]

I was going to set a schedule for the children where in study time they can only access web pages I have agreed. I did wonder whether it would be possible for the router to display a basic web page if they try and access other pages - either customisable or to the affect that the administrator has blocked unauthorised web content at this time.

A further enhancement - though this would be quite a biggie would be to have the ability for the user to then request access and have it add it into the list of authorised pages when approved
