rathole-org/rathole

A secure, stable and high-performance reverse proxy for NAT traversal, written in Rust

rathole, like frp and ngrok, can help to expose the service on the device behind the NAT to the Internet, via a server with a public IP.

A full-powered rathole can be obtained from the release page. Or build from source for other platforms and minimizing the binary. A Docker image is also available.

The usage of rathole is very similar to frp. If you have experience with the latter, then the configuration is very easy for you. The only difference is that configuration of a service is split into the client side and the server side, and a token is mandatory.

To use rathole, you need a server with a public IP, and a device behind the NAT, where some services that need to be exposed to the Internet.

Assuming you have a NAS at home behind the NAT, and want to expose its ssh service to the Internet:

Create server.toml with the following content and accommodate it to your needs.

Create client.toml with the following content and accommodate it to your needs.

So you can ssh myserver.com:5202 to ssh to your NAS.

To run rathole run as a background service on Linux, checkout the systemd examples.
