Nginx reverse-proxy Generator

The NGINX Reverse Proxy Generator creates secure, high-performance proxy configurations. It seamlessly forwards external traffic to internal Node, Python, or Go containers while masking backend IP addresses and terminating SSL.

IP Masking

Hides backend network topology from the public internet.

Header Forwarding

Injects X-Forwarded-For headers to preserve client IPs.

How it Works

1

Define Upstream - Specify the internal hostname and port of your application (e.g. `api:3000`).

2

Configure Server - Set the domain name and listening port.

3

Generate Config - Download the completed `nginx.conf`.

Best Practices

A reverse proxy acts as a secure gateway between the internet and internal services.

proxy_pass

Directly forwards raw traffic

Coupled with explicit header forwarding

Connection

Closed after request

Upgraded for Websocket support

Example Output

Here is a real generated snippet matching the production best practices above:

server {
    listen 80;
    server_name api.example.com;

    location / {
        proxy_pass http://backend:3000;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_cache_bypass $http_upgrade;
    }
}

Advanced Configuration Logic

Writing reverse proxy blocks manually often leads to websocket disconnection issues or incorrect client IP logging. If you forget to forward the `Upgrade` and `Connection` headers, real-time applications (like Socket.io) will instantly fail. Furthermore, if you don't correctly set the `X-Real-IP` and `X-Forwarded-For` headers, your backend application will think every single request is coming from 127.0.0.1, breaking rate limiting and analytics.
