I want to block all chat programs by blocking IP addresses
Posted on 2006-10-26
I want to prevent a group of users from using any chat program, whether it is through a web interface or through an .exe. I believe the easiest way would be to block the IP addresses of the chat programs. Since this is for a small number of users, I can do it on their local workstations (XP). I also can do it on the server although I would prefer to do it locally. I do not know how to block an IP address.
