SOCKS Proxy service is very similar to the Winsock Proxy service, but it can be used by most popular client operating systems. With SOCKS Proxy, by default, all SOCKS requests are denied. You can allow or disallow requests to and from Domains or Zones, IP subnets, or All. Logging can be used to track clients as in the previous services. SOCKS provides secure communication between the client and server and can provide redirection for non-Windows platforms. It uses TCP/IP as the protocol.
