back-proxy

Reversing proxy to you gadgets or home http-server behind NAT with dynamic WAN ip. Needs two "servers": one in Internet for you connects for proxing and second in you home for serve proxy requests.

How its works

After starting, client.js make permanent pipe to server.js. On new connection from any device to public - server.js send data to pipe and client.js opens same connection to shared (and so one on next connections). When connection dropped by any side - on server.js or client.js - other end drop connection to.

Scenario

You want to access to you gadget (like http://tessel.io who have own web server) in home LAN (ip: 192.168.0.201).

Steps

Create config (used for client and server scripts)

Please copy config.default.js to config.js and modify to you needs:

module.exports = {

	// Public server config (where you connect to access LAN server)
	public: {
		host:	'1.2.3.4',
		port:	'8080'
	},

	// Upstream server config (where proxy from LAN connect)
	upstream: {
		host:	'1.2.3.4',
		port:	'8888'
	},

	// Shared server config (server in LAN)
	shared: {
		host:	'192.168.0.201',
		port:	'8000'
	}

};

Run node server.js on server 1.2.3.4

Run node client.js on you home PC

Try it

For http-server - browse to http://1.2.3.4:8080/ and you will see page from you home http-server http://192.168.0.201:8000

Note: any protocol supported, not only http. This scripts only traverse data you send to socket.
