[itronic.at] Subject: [pve-devel] arp-filter doesn't work with alias X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 05 Dec 2023 11:11:00 -0000 Hi, using an alias in ipfilter-net0 doesn't create an tapxxx-OUT-ARP entry in ebtables. It works if the ipfilter-net0 ipset is an IP-address. Other topic, is there a reason why no incoming arp request filter is set automatically? I asked this back in 2018 and found it a couple of times on the forum. Having many unused ips creates a flood on all VMs which is a waste on resources and a kind of information leak. thanks Harald -- ITronic Harald Leithner Lichtäckerstraße 22, A-2522 Oberwaltersdorf Tel: +43-1-545 0 604, Mobil: +43-699-123 78 4 78 Mail: leithner@itronic.at | itronic.at
