1. We are working on a large LAN, which is not secure. People can use packet sniffers to check the data that is going from my PC to the proxy server and discover if the data requests include MSN communication. I need a method whereby the traffic being generated from my IP cannot be spoofed and sorted. In short, I need an encryption method. Please suggest something.
2. Secondly, people on the network are also using software that allows them to generate requests to the proxy server and make it seem as if the requests are generated from my IP. Its like virtually using my IP for sending requests to the proxy and getting the privileges that my IP has. Help.
