My homelab has gone from a simple Raspberry Pi to a Ubiquiti network-stack, a firewall, and 3 servers. This entire ecosystem powers my smart home, my web apps and other services I am self-hosting
The Firewalla Purple is in my mind the best home firewall for your personal use. The firewall is affordable, feature-rich, plug-n-play, and has a powerful iOS app for your work from home setup.
