⁠Simple TCP Proxy

Given the scenario:

                             10.0.1.0/24                10.0.2.0/24
  +-------------+   (VPN)   +------------+   (VPN)   +-----------------+
  | My computer | --------- |  Jump Box  |-----------| Internal Server |
  +-------------+   (SSH)   +------------+           +-----------------+
                             [Public IP]

If you need to access from your computer a service running on the Internal Server, but the VPN/SSH only give you access to the Jump Box machine. The easiest way to do it is using socat⁠ to create a simple TCP proxy.

But sometimes install socat⁠ can be annoying and you need to remember the syntax.

This docker-image makes easier to use socat⁠ with the simple command: docker run -d -p PORT:PORT robsonpeixoto/simple-tcp-proxy HOST PORT
