I have firmware 4.70.6. I want to be able to restrict some web sites so that they are unavailable to my kids computers. I have tried to set this up in on the Internet Access page. I set up each computer using their MAC address then entered the web sites that I don't want accessed. Clicked on save setting. Return screen said it was successful but when I go to thier computer and type in the site they still open. I have tried resetting the router but that has not helped either. Also, if I could get this to work I would sure like to enter more addresses then just four per computer. I don't want to subscribe to the parent control as that just seems like more unnecesary expense. Thanks for any help.
