How to enable firewall for container network device?

[Tumetsu]

Is your feature request related to a problem? Please describe.
I want to automatically set security group and assign said security group to my lxc container. I can do that by using security group resource and firewall options resource. However, to me it looks like Proxmox requires you to check one more checkbox to actually enable the firewall. That checkbox is located in Network page of a container:

Is there support for toggling that to true? For me it seems to default false. I checked container resource's docs but its network part did not have any mention of firewall. Am I missing something here?

Describe the solution you'd like
Add boolean flag for network device firewall.

Hey @Tumetsu 👋🏼
Indeed, there should be a firewall argument for network adapters, both for LXC and VM. Will add it in the next release.

Thanks for reporting!

LXC example:

resource "proxmox_virtual_environment_container" "example" {
  ...

  network_interface {
    name     = "veth0"
    mtu      = 1450
    firewall = true
  }
}

Thanks for quick fix! Got my firewall settings IaC'd now 👍
