Subject: [pve-devel] [PATCH proxmox-ve-rs v2 02/17] firewall: add bridge firewall config parser
Date: Thu, 10 Oct 2024 17:56:35 +0200	[thread overview]
Message-ID: <20241010155650.255698-3-s.hanreich@proxmox.com> (raw)
In-Reply-To: <20241010155650.255698-1-s.hanreich@proxmox.com>

We introduce a new type of firewall config file that can be used for
defining rules on bridge-level, similar to the existing
cluster/host/vm configuration files.
