Hi, This can easily be implemented by using VLAN's and judicious usage of interface device bridge(s). Here is a very important use case: IoT devices should ALWAYS be put onto a guest network. Security in such devices is an afterthought as history has shown time and time again, repeatedly, across major vendors and popular consumer product offerings. A critical piece of mitigating IoT device exploitation is by effectively isolating each device connected to a guest network from each other, including from the main network.
