I would like to have the log of websites visited by some of my employees and block some through my firewall. I am looking for a somple solution, free if possible. My firewall does not log requests (D-Link DFL-800) but can block sites, so I have to find someway to log the web activity. I do not want to install a proxy server or so, because I am an IT manager and the people I want to monitor are IT support staff, so they will know that. I think installing some application on each computer is the solution but is there another way? If not, what is the program to install? Any advice is highly appreciated.
Thank you very much.
