HassOS proxmox firewalling

Hi

I installed HassOS on my proxmox server using this convenient script: https://github.com/tteck/Proxmox/raw/main/vm/haos-vm-v3.sh

After the installation went setting up the firewall using proxmox’s (node=>HassVM=>Firewall=>enable and set up the rules in node=>HassVM=>Firewall)

But when I launch the VM no rules are applied, I can access HassVM on port 8123 from anywhere/any subnet

Is it because HassOS is built on buildroot? I thought the rules on proxmox were applied at host’s level, not at VM’s level, so it doesn’t make any sense.

Can I firewall using proxmox or am I stuck using my router’s firewall?

Yup… I feel dumb…

So I’ve search for an entire week to only find today that when you create a HassOS VM with this script, you have to go to Datacenter=>node=>Hass VM=>hardware, click on network device, edit and check the firewall box…
