bore

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

# Step 1: Installation (requires Rust)
cargo install bore-cli

# Step 2: On a remote server at example.com
bore proxy

# Step 3: On your local machine
bore local 8000 --to example.com:9000

This will expose your local port at localhost:8000 to the public internet at example.com:9000.

Inspired by localtunnel and ngrok, except bore is intended to be a highly efficient, unopinionated tool for real production workloads that is simple to install and use, with no frills attached.

Detailed Usage

TODO

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.
