Traffic forwarder

Tcp Port Forwarding software also can work as network bridge for redirecting TCP network traffic from one network card to another one.
This tool is used for testing some services, firewall and intrusion detection systems. The program can also be used for debugging programs and configuring other network tools.

Installation

npm install xrelay -g

How to use:

Create a forwarder:

xrelay <from> <to>

A practical example

In my enviroment development, i have a Servlet and wanna connect to a device called AP or Acess Point (we can't connect directly) throught a Broker Server. Then AP also return data to servlet throght broker.

Context 1: Request to device at (http://10.84.3.234:30005/)
(1) Mediation(Poller) ---> (2) Broker (30005) ---> (3) Access Point
Context 2: Response to ACS Servlet at (http://10.2.4.238:8090)
(6) Mediation(Servlet) <--- (5) Broker (8090) <--- (4) Access Point

Solution

Create two node applications on broker using xrelay as following example

xrelay 30005 10.84.3.234:30005  
xrelay 8090 10.2.4.238:8090  

Note: xrelay will parse 8090 or localhost:8090 or even example.com:8090
