Rathole is a high-performance reverse proxy and NAT traversal tool written in Rust. It functions as a secure tunneling server and client architecture designed to expose local services to the internet by forwarding traffic from a public IP to a private device behind a firewall.
The system establishes encrypted tunnels between a public server and a private host to ensure private communication. It utilizes token-based authentication to validate identities between the server and client for each individual service.
The project provides TCP and UDP port forwarding and manages private tunnels to facilitate remote service exposure. It includes capabilities for multiplexing multiple local services over a single network tunnel and supports dynamic configuration reloading to update active services without restarting the process.
