ABSTRACT:
A system provides a proxy connection by intercepting a control connection and a data connection between a client and a server. A proxy device receives a control connection request from a client and establishes a proxy control connection with a server in response to the control connection request from the client. The proxy device then receives a data connection request from the client. In response to the data connection request, the proxy device establishes a data connection with the server at a server-selected or dynamic port of the server and establishes a data connection with the client at a fixed port of the proxy device. Using this technique, the proxy device transparently intercepts both the control connection and the data connection from the client and transmits data received from the server-selected port of the server to the client through the fixed port of the proxy device.
