Hi Guys I work for a little company whom is not willing to spend. The guys at work are abusing the internet. We get access to the net via our router, which assigns us IP's.(Router is our DHCP server).We are on a workgroup. I want to control the access to the internet and leave mail open for sending and recieving. My company doesn't want to get a server license so it leaves ME in a pickle, cause im now not sure how to do this and dont know any open source software that can help me. Please help somebody
