A simple TCP proxy that may be used to access a service on another network. An extensible replacement for socat when used thus

socat TCP-LISTEN:port1,fork TCP:host:port2

port1 is where socat listens for incoming requests. host and port2 are the host and port where the actual service is listening at.

To achieve the same with node-tcp-proxy

node tcpproxy.js  --proxyPort [port1] --serviceHost [host] --servicePort [port2]

Install node-tcp-proxy from npm

sudo npm install -g node-tcp-proxy

To create a proxy in your own code

var proxy = require("node-tcp-proxy");
var newProxy = proxy.createProxy(8080, "hostname", 10080);

To end the proxy

newProxy.end();
