Not sure if this is possible: want to restrict access to certain sites during certain times (e.g., facebook.com during homework hours ) but allow other internet access at the same time. It does not seem possible to set restrictions that granular. Facebook is either always on or always off, or any internet access can be blocked during certain times, but not the intersection of the two. Is there a 3rd party firmware that provides this? And is compatible with the WRT54G v6? Expert level challenge: how to block Skype during the same timeframe?
