And http://forums.opendns.com/comments.php?DiscussionID=3414 seems to note that it is possible if you use OpenDNS so that may be an option here.
I would be guessing you want a Net nanny app such as http://www.netnanny.com/support/top15 where I think question 6 starts to answer how to create reports.
However I find most folk tire of the flood of information pretty quickly or find out they are watching something like this cartoon.

Sounds tedious and may result in folks getting upset?

I have a Comcast Arris Interactive model TG862G router/modem connected to a desktop computer. We can connect wireless from our laptops. What I am trying to do is get a log of sites visited. Is there a way I can use my desktop to log the sites through the router/modem?
Thanks
