How to limitate 8006 port on the web

[sebastiano]

Hi, for reasons of need, I need to remotely access some proxmox installations via web interface, I would like to limit access to my public IP, or find a solution that limits the exposure of this port on the web, could anyone help me give some tips or tell me if there are any guides on this?
I looked for something online but nothing. I'll start by saying that unfortunately not all hosts have proxmox 8.x, I have one with version 6.x.
Thanks to anyone who can direct me

proxmox firewall ?

Access via public IP? That means you want your hosts to have open internet access?

That is a bad idea for many reasons.

I would suggest a private VPN to each site so you can securely access the hosts.

You should never expose your management to the world wide web, Proxmox VE is basically insecure install, it should have separate VLAN even on LAN. You need a VPN or at the least reverse proxy. If it's a one off, I would even SSH tunnel into the LAN (onto some other host than PVE) and take it from there.
