I need to block the Internet and leave the MSN working on a Windows XP computer in a small business network. Our router doesn't provide anything that could effectively do it.
I have tried blocking the Internet Explorer through content advisor.... They just bring a flash drive with firefox/chrome/opera portable and use the Internet. I have tried to block these applications but there are too many to keep track of.
I know I can totally block the Internet giving the computer a blind DNS or just change the gateway but I gotta leave MSN working. I thought about a proxy but we don't have a spare computer to serve this purpose.
Any ideas? I really appreciate it. Sadly we can't find employees who respect our company rules and we gotta do it.
Is it just one computer you are trying to block internet?
I bet you can get a firewall program to do it for you. Just use windows built in firewall, and block outbound traffic port 80.
I do like Emerald idea of just adding a second router. You can get a cheap on for like 50-70. and that will mostly likely give you better security as well.
