bore

A modern, simple TCP tunnel* in Rust that exposes local ports to a remote server, bypassing standard NAT connection firewalls. That's all it does: no more, and no less.

* plus HTTPS proxying by Traefik in our case

Quick start

• abra app new bore
• abra app config <app-name> (set SECRET in .env if you want authentication)
• abra app deploy <app-name>

Usage

Install the cli on your machine: https://github.com/ekzhang/bore

Then you can expose a local port (eg. port 4000) through the tunnel:

bore local 4000 --to yourapp.yourserver.tld --port 1 --secret <SECRET>

(or any number from 1 to 10 for the port, which will match the subdomain used)

Then access it at e.g. https://1.yourapp.yourserver.tld

Configuration

• SECRET: Optional authentication secret. Clients must provide this to create tunnels.

Notes

• Requires wildcard DNS (*.yourapp.yourserver.tld) pointing at your server.
• Traefik will set up TLS and proxies HTTPS to bore's tunnel ports.
• To add more tunnel slots beyond 10, add corresponding Traefik labels in compose.yml and increase MAX_PORT.
• TODO: find a way to put the secrets in docker secrets instead of env (seems not possible with current docker image since it uses scratch with no shell)
