Reverse Proxy ​

A reverse proxy sits between your users and your backend services, forwarding requests and providing additional features such as SSL termination, load balancing, and enhanced security.

Toggling the reverse proxy setting ​

The installer asks whether you're using a reverse proxy (Nginx or a Cloudflare proxied DNS record) and stores the answer in INSTALL_DIR/.5stack-env.config.

To change it later, edit that file and set:

env
REVERSE_PROXY=false

Use true if you front the panel with Nginx or Cloudflare's orange-cloud DNS, false if traffic reaches the panel directly.

After saving, re-run ./update.sh so the new value is applied.

Cloudflare Proxies ​

Cloudflare acts as a reverse proxy when you enable the "Proxied" DNS (orange cloud). Incoming traffic to your domain first passes through Cloudflare before reaching your server, providing DDoS protection and performance benefits.

Nginx Proxy ​

To use Nginx as a reverse proxy, configure it to listen on HTTPS (port 443) and forward requests to your backend services.

Below is a basic Nginx configuration example:

nginx
server {
    # Listen on HTTPS port 443
    listen 443 ssl;
    server_name your-domain.com *.your-domain.com;

    # SSL certificate configuration
    ssl_certificate /path/to/fullchain.pem;
    ssl_certificate_key /path/to/key.pem;

    # Proxy configuration
    location / {
        proxy_pass https://<YOUR_HOST_MACHINE_IP>:443;

        # Standard proxy headers
        proxy_set_header Host $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto $scheme;

        # WebSocket support
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}
