ProxyNT is a reverse proxy server that can expose a local server to the internet through NATs and firewalls

Features

1. Open port mapping via browser anytime and anywhere
2. Encrypted transmission between public network server and local network client via WebSocket
3. Few dependencies, one-click installation via pip
4. Stable, automatically reconnect, and already in production environment
5. Support for rate limiting

Common Scenarios

1. Hosting website server at home
2. Managing IoT devices

Installation

pip install -U proxynt

Example: Accessing an Internal Network Machine via SSH

Suppose the public server's IP is 192.168.9.224.

1. Create config_s.json file on the public network machine

config_s.json content:

{
  "port": 18888,
  "password": "helloworld",
  "path": "/websocket_path",
  "admin": {
    "enable": true,  
    "admin_password": "new_password"  
  }
}

Then start: nt_server -c config_s.json

Explanation:

• port: Listening port
• password: Connection password
• path: WebSocket path
• admin: Management page configuration (optional)
• admin.enable: Whether to enable management page
• admin.admin_password: Management password

2. Create config_c.json file on the local network computer that needs to be accessed

config_c.json content:

{
  "server": {
    "port": 18888,
    "host": "192.168.9.224",
    "https": false,
    "password": "helloworld",
    "path": "/websocket_path"
  },
  "client_name": "home_pc",
  "client": []
}

Then start: nt_client -c config_c.json

Explanation:

• server: Configuration of the server to be connected, including port, IP address, whether to use HTTPS, password, and WebSocket path.
• client_name: Client name, needs to be unique.
• client: Empty array.

3. Open the server webpage http://192.168.9.224:18888/websocket_path/admin and add a port:

Explanation: The management page path is WebSocket path + /admin .

4. Configuration succeeded, use SSH to connect:

ssh -oPort=12222 [email protected]

        "admin_password": "new_password"  // Password for admin page
    }
}
