  <p style="color:var(--text-muted);margin-bottom:1rem">Install Nginx alongside Apache on this VM. Nginx listens on ports 80/443 and forwards to Apache. Best for SSL termination and caching.</p>
  <ol style="color:var(--text-muted);margin-bottom:1.5rem;padding-left:1.2rem;line-height:1.8">
    <li>Click <strong>Install Nginx Locally</strong> on the main Nginx Proxy page</li>
    <li>Move Apache to port 8080: edit <code>/etc/apache2/ports.conf</code> → change <code>Listen 80</code> to <code>Listen 8080</code></li>
    <li>Update upstream in all proxy hosts to <code>http://127.0.0.1:8080</code></li>

  <p style="color:var(--text-muted);margin-bottom:1rem">Run a dedicated Nginx proxy VM in front of this NovaCPX VM. Traffic flows: Internet → FortiGate → Nginx Proxy VM → NovaCPX VM (Apache).</p>

    <li>Create a new VM on Proxmox (Ubuntu 22.04, 1 vCPU, 1GB RAM)</li>
    <li>Run the setup script below on the new VM as root</li>
    <li>Point FortiGate VIPs to the proxy VM IP (ports 80/443)</li>
    <li>Set the proxy upstream to this NovaCPX VM IP (<code>http://10.48.200.110:80</code>)</li>
    <li>Add proxy hosts for each domain from your NovaCPX admin panel</li>
