Rathole
Rathole is a reverse proxy tunneling tool designed to expose local services behind firewalls and network address translation to the public internet. It functions as a secure tunneling infrastructure that enables remote access to private network resources without requiring manual router port forwarding configurations.
The system utilizes a client-server architecture where a public-facing gateway coordinates with a private-network agent. It distinguishes itself by multiplexing multiple logical service connections through a single persistent TCP stream, which reduces the overhead of maintaining individual connections. To ensure security, the platform employs a dedicated control plane that manages service registration and verifies agent identity through token-based authentication before establishing any tunnels.
The software handles high-concurrency traffic by utilizing non-blocking input and output operations within an asynchronous event loop. Data transmission is optimized through zero-copy buffer forwarding, which relays packets between network endpoints using shared memory to minimize processing requirements.
