dnsmasq Optional. Scan Method 3. Check devices using DHCP server
IEEE HW DB Necessary to identified Device vendor

If you’re still not satisfied by these tools, there are a couple of other FOSS applications worth considering. Although Pi.Alert is often hosted on Raspberry Pi boards, you can also run them inside containers on your Proxmox machine to reinforce the security of your home server. For frequent travelers who want to access their home lab from an external connection, you can deploy a Wireguard container and set up a reverse proxy via Nginx to safely access your favorite services without exposing them to security threats.

Why waste money on an enterprise firewall when you can build your own from old PC parts?
