Configuration of Nginx TCP proxy service in windows

Nginx is not only used as web proxy server(support http and https protocol), it’s also can be used as regular TCP proxy server,supporting any TCP port, such as TCP 3306, 3690, 3389, 22 and so on.

It can realize the following feature. Client isn’t able to access source server A and source server B directly, but Server C can. we configure proxy service on server C, Thus client can visit server A and server B through proxy service on server C.

In this passage, I’ll introduce configuraton of nginx TCP proxy service briefly.
