Node UDP Hole punching

In this experiment it is attempted to use the UDP Hole punching technique to initiate a connection between two clients behind NAT (without port forwarding).

Goals

The first goal is to create a simple script that allows sending UDP packets from client to client, in both directions (current state). Future goals include the development of a library that offers this method in a more extensible manner.

Usage

A public machine acts as a rendezvous server (running rendezvous.js), two clients behind NAT start client.js. A client can ask the rendezvous server to help them him to connect to another client using the TCP hole punching procedure.

1. Server node rendezvous.js

2. Client A node client.js [server] [nameA]

3. Client B node client.js [server] [nameB] [nameA]

node-upd-hole-punching's Issues

Was this successful?

Hi, this is more of question than an issue. Was this prototype successful in performing the hole punch?
