SockRedirector

Redirects TCP connections from one IP address and port to another

I have used this tool for many years. This tool allow to redirect the TCP data from a port of one ip to another remote port of a remote machine.

This tool is very usefull in complex network architecture, where there are some firewall that are open only from one machine to another.

In this situation you can put sockRedirector server on thrusted machine, and connect to remote server using this machine

The concept is very similar to a proxy, without the limitation of use only http connection or the problem to write a socks interface.

Java sockRedirector is written in Java.

Use this program in Linux, Windows, AIX, AS/400 or all environment you want.
