Wireless network question ... can I tell where users are surfing?

[dud]

I currently have a 6+ Mbs connection ported through a linksys wireless G router shared by three laptops. Question: Is there any way to tell what sites/activity is ocurring through any of those connections? My concern is that one of the three (3) users may be doing things I do not want them to do with my access point.

Thanks ...

Tons of options, transparent proxy comes to mind

DD-WRT may be an option, depending on what content you are trying to restrict.

If you route your DNS through opendns, you will be able to see website traffic. This wont help you see any activity like torrenting that goes right to specific IP's.

I second this, to give a little more details, as I do not know how experienced you are with these kinds of things, every time you go to a website like www.anandtech.com you query a DNS server to match that name with an IP. If you use openDNS you can create an account that keeps track of and logs these requests. Check out this http://www.opendns.com/start/ It's free.

Unfortantely it's easy to bypass on the client machine. So you still might have to consider a transparent proxy Server or a DD-WRT solution. I just double checked on my DD-WRT enabled router and there does seem to be a feature that will log outgoing/incoming connections. However there isn't anyone at my house to initiate a connection at this time so I couldn't test it for sure. DD-WRT is also free and 2nd easiest next to openDNS, and impossible to bypass without physically changing cables, that you should notice.
