Back To Basics: Troubleshooting Proxy Server 2.0 Page 4
The SOCKS Proxy Service
The SOCKS Proxy Service allows Internet access for your non-Windows clients that need access to protocols not supported by the Web Proxy Service. You might think of the SOCKS Proxy Service as the Mac/UNIX version of the WinSock Proxy service. However, the two services are managed quite differently from one another.
Proxy Server 2.0 supports SOCKS version 4.3a and does not support SOCKS version 5.0. This is important to keep in mind if you have games or other applications that require SOCKS support.
Security configuration of the SOCKS Proxy Service is somewhat clumsy when compared to the Web and WinSock Proxy configuration schemes. The SOCKS Proxy Service is not security account aware. You configure access based on source and destination IP addresses or network IDs. Figure 3 shows an example of the SOCKS Security configuration dialog box.
It is interesting to note that the SOCKS Proxy Service is implemented as a part of the Web Proxy Service, and therefore it too is dependent on the WWW Service of the IIS Server to function properly.
