Transparent Proxy and Classic Proxy
We'll begin our discussion by taking a look at the way WinProxy works in your computer:
Figure 3.16: How WinProxy Works
To give you some perspective, all of WinProxy 2.1-a Classic Proxy-could fit within the functional box labeled "WinProxy." The features are mostly within the functional boxes labeled "Ositis SHIM/CAM" and "Ositis Firewall."
WinProxy 2.1 worked entirely at the application (user) level, with the same access to Winsock and the TCP/IP stack as any other application. Version 3.0 and above work at both the application level and at a level below the tcp/ip stack. Both levels can communicate with each other to provide you maximum flexibility and a peerless firewall.
User settings for these "lower levels" affect WinProxy in two ways: (1) how it interacts with the applications on your client machines, and (2) how it interacts on the Internet connection
