A small proxy that proxies UDP packets from one port to another depending on the source IP.

Installation

You can download the binary for your platform from the releases page or alternatively use the Docker image.

Usage

--port <port>     The port to listen on
--forward <source-ip>:<remote-ip>:<remote-port>
                  Forward packets from <source-ip> to <remote-ip>:<remote-port>, you can specify --forward multiple times
--log-level <level>
                  Set the log level (trace, debug, info, warn, error, fatal, panic)

With the binary:

./udp-proxy --port 5000 --forward <source-ip>:<remote-ip>:<remote-port>

Or with Docker:

docker run --rm -p <listen-port>:<listen-port>/udp ghcr.io/netresearch/udp-proxy --port <listen-port> --forward <source-ip>:<remote-ip>:<remote-port>
