Safehaven Architecture provides a secure tunneling solution for private network communication on Linux. The architecture involves setting up a tunnel server and client with specific flags for configuration. By following the implementation details on the blog post, users can build the project, set up the server in server mode, and ensure proper IP forwarding for successful communication. It is important for the server to know how to reach the private network to prevent packet loss. The demo showcases the functionality of the architecture. Unique features include the option to globally route all traffic to the tunnel server and monitoring the setup through ping replies.
