wgtunnel

wgtunnel is a simple WireGuard tunnel server. Clients can register themselves to the server with a single API request (done periodically in the background in case the server restarts), and then connect to a WireGuard endpoint on the server over UDP to tunnel.

Generated URLs are unique and are based on the WireGuard public key. Wildcards for each tunnel are also semi-supported, using hyphens instead of periods to allow for TLS.

This is used by Coder to create tunnels for trial/demo deployments with globally accessible URLs.

Deployment

Deploy tunneld onto your server and configure it with environment variables or flags. Point the DNS entries ${base_url} and *.${base_url} to the server. If you want to use HTTPS, setup a proxy such as Caddy in front of the server.

tunneld is available on GitHub releases or can be installed with:

$ go install github.com/coder/wgtunnel/cmd/tunneld

or by running make build/tunneld.

You can also use the Docker image ghcr.io/coder/wgtunnel/tunneld.

Usage

Either use tunnel for easy usage from a terminal, or use the tunnelsdk package to initiate a tunnel against the given API server URL. Remember to store the private key for future tunnel sessions in a safe place, otherwise you will get a new hostname!

tunnel can be installed with:

$ go install github.com/coder/wgtunnel/cmd/tunnel

or by running make build/tunnel.
