a simple, cross-platform, multi-client TCP proxy for Old-school RS2/JS5

rs-proxy is a cross-platform, multi-client TCP proxy written in rust, that is designed for those "one-time" tasks where you usually end up spending more time installing a proxy server and setting up the myriad configuration files and options than you do actually using it.

rs-proxy is completely asynchronous and built on top of the tokio async runtime. It was written to serve as an example of how bidirectional async networking code using rust futures and an async framework would look and is intentionally kept easy to understand. The code is updated regularly to take advantage of new tokio features and best practices (if/when they change).


rs-proxy is a command-line application. One instance of rs-proxy should be started for each remote endpoint you wish to proxy data to/from. All configuration is done via command-line arguments, in keeping with the spirit of this project.


    -b, --bind BIND_ADDR
                        The address on which to listen for incoming requests,
                        defaulting to localhost.
    -l, --local-port LOCAL_PORT
                        The local port to which tcpproxy should bind to
                        listening for requests, randomly chosen otherwise.
    -t, --timeout
                        Sets the timeout in seconds to stop after no activity

Where possible, sane defaults for arguments are provided automatically.


rs-proxy is available via cargo, the rust package manager. Installation is as follows:

cargo install rs-proxy
