ForwardMachine

Port forwarding service configurable in runtime.

How does it work?

ForwardMachine listens on TCP port for forward requests.

These requests are simple, they consist of host:port, e.g. host.example.com:3000.

As response, host and port where forwarding has been set up is returned.

Installation

$ gem install forwardmachine

Usage

Start forwarder for host proxy.example.com

$ forwardmachine --forwarder-host proxy.example.com --ports-range 8000..9000

Control server by default will listen on localhost:8899. Connect to it and create a new forwarder (here we use nc tool).

$ nc localhost 8899
  internal1.example.com:7777
  proxy.example.com:8000

proxy.example.com:8000 is forwarded to internal1.example.com:7777

$ nc localhost 8899
  internal2.example.com:9999
  proxy.example.com:8001

proxy.example.com:8001 is forwarded to internal2.example.com:9999
