mumble-web-proxy

mumble-web-proxy is a Mumble to WebSocket+WebRTC proxy.

The Mumble protocol uses TCP for control and UDP for voice. This proxy bridges those to WebSocket for control and WebRTC for voice.

While not limited to, its primary use-case is allowing mumble-web to connect to vanilla Mumble 1.2/1.3 servers.

Note that it requires an extension to the Mumble protocol which has not yet been stabilized and as such may change at any time, so make sure to keep mumble-web and mumble-web-proxy in sync.

Installing

Prerequisites

• Rust 1.45+ (e.g. via rustup)
• libnice development headers (libnice-devel on Fedora, libnice-dev on Debian)
• OpenSSL development headers (openssl-devel on Fedora, libssl-dev on Debian)
• clang (clang on Fedora and Debian)

Building

For now, mumble-web-proxy must be built from source. Pre-built binaries may be provided at a later point in development.

Make sure you have Cargo (Rust's package manager) installed (e.g. via rustup), then run:

git clone https://github.com/johni0702/mumble-web-proxy
cd mumble-web-proxy
cargo build --release

The final binary will be at target/release/mumble-web-proxy.

Running

mumble-web-proxy can only accept insecure websocket connections, so you will want to run it behind some web server which can terminate TLS. See mumble-web's README for an example.

Run mumble-web-proxy --help to see available options. E.g. if you want the proxy to listen on port 64737 and connect to your Mumble server at mumbleserver:64738, run:

mumble-web-proxy --listen-ws 64737 --server mumbleserver:64738

Instead of specifying all the options directly in the arguments, you can also use --config <file> to point mumble-web-proxy at a toml file which contains them:

listen-ws = 64737
server = 'mumbleserver:64738'

Firewalls or NAT

If your mumble-web-proxy is running behind a firewall or NAT, you need to allocate a range of ports to it which it can use for ICE connection establishment.

mumble-web-proxy --listen-ws 64737 --server mumbleserver:64738 --ice-port-min 20000 --ice-port-max 21000

For NATs, you additionally need to provide it with its publicly reachable IP address(es):

--ice-ipv4 1.2.3.4 --ice-ipv6 1:2:3:4:5::6
