jbruned/port-forwarder repository overview

⁠Docker port forwarder

This is a really simple docker image which just listens on the specified port and forwards the traffic to a given IP address and port.

⁠Setup

Some environment variables are required to run the container:

• LISTEN_PORT: the port to listen on
• DESTINATION_IP: the IP address to forward to
• DESTINATION_PORT: the port to forward to

If you want to redirect traffic to the host, you can use the special IP address host.docker.internal (see Docker documentation⁠ for more information). In particular, if you are using a Synology NAS, you can add the following argument to the docker run command: --add-host=host.docker.internal:host-gateway.
