We're looking for a gateway device, preferably a wireless firewall, that records all pc and internet activity. Where are users going, what are they typing, etc? We know that there are programs which you can install on a server and on the clients to do this, but we're looking for something less invasive and flexible so that it records any activity that goes through the network. It's for residential networks, so it has to be simple and hidden from the users, being children.
The only way I can see doing it over a server is if it worked like a proxy and computers were required to download the software before they could get internet access.
