Hi folks,
The intention is to set up a small homelab. Its a Lenovo mini PC Intel i5-6500, 32GB RAM.Bare Metal, has proxmox on it. Followed by pfSense installation, All works well, until I create vmbr1 in proxmox AND create a LAN interface in pfSense. The moment I ADD and save this LAN interface (via assigned IP :=192.168.2.1), the pfsense Web GUI goes out.

Steps Taken to Resolve the Issue:
  1. Network Configuration:
    • Assigned vmbr1 as the LAN interface in pfSense.
    • Verified that LAN is reachable via ping (192.168.2.1).
  2. Checked WebGUI Service:
    • Ran ps aux | grep php-fpm to confirm if WebConfigurator is running.
    • Restarted WebGUI using /etc/rc.restart_webgui.
    • Forced a reset via pfSsh.php playback resetwebgui.
  3. Firewall & Access Checks:
    • Disabled firewall temporarily using pfctl -d.
    • Tried accessing http://192.168.2.1 instead of HTTPS.
    • Cleared browser cache & tried different browsers.
  4. Checked Lighttpd Service:
    • Verified installation with pkg info | grep lighttpd.
    • Attempted manual restart using /usr/local/sbin/lighttpd -f /var/etc/lighty-webConfigurator.conf.
    • Reinstalled Lighttpd (pkg install -y lighttpd).

Despite all these steps, the WebGUI is still inaccessible, but LAN is confirmed working via ping. Looking for further guidance or alternative troubleshooting steps.
 
That’s Proxmox, pfSense uses 443 by default.

@slash1814 Are you adding this IP inside pfSense? Typically LAN is changeable after the initial install. Also each interface needs a unique subnet. What does the pfSense console show?
