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.

# Installation (requires Rust)
cargo install bore-cli

# On your local machine
bore local 8000 --to bore.pub

This will expose your local port at localhost:8000 to the public internet at bore.pub:<PORT>, where the port number is assigned randomly.

Like localtunnel and ngrok, except bore is intended to be a highly efficient, unopinionated tool for forwarding TCP traffic that is simple to install and easy to self-host, with no frills attached.

Detailed Usage

This section describes detailed usage for the bore CLI command.

Local Forwarding

TODO

Self-Hosting

As mentioned in the startup instructions, there is an public instance of the bore server running at bore.pub. However, if you want to self-host bore on your own network, you can do so with the following command:

bore server

That's all it takes! After the server starts running at a given address, you can then update the bore local command with option --to <ADDRESS> to forward a local port to this remote server.

Protocol

There is an implicit control port at 7835, used for creating new connections on demand. This can be configured in the command-line options.
