If you have networking equipment that can support them, setting up virtual local area networks (VLANs) makes sense from a security and management perspective. Your devices will still think they’re on a physical LAN and will be able to talk to each other, but the different VLANs will only be able to talk to each other if you allow it.That’s perfect for keeping insecure IoT devices away from your data, your data away from your guests, and your guests away from the contents of your computer. Unless you decide you want them to talk to each other, of course. It essentially gives you multiple networks from one set of equipment, and makes your life much easier as a budding homelabber or network admin.
