At my home, I have a relatively common network setup with a modem (in bridge mode), two ASUS mesh routers (ethernet backhaul) and a few unmanaged switches.
Now I need to have internet connectivity in the basement garage, which is somewhat a public place. For this, I connected one Devolo Powerline Adapter to my router, and one in the Garage. Unfortunately, there is also a LAN port at the adapter. I want to prevent someone connecting to my home network.
Now I'm asking my self what would be the best/cheapest way to isolate this port. Internet through WLAN should be possible but no home network access through the RJ45 port.
Could it be solved with a managed switch? What would be the feature I need for this? VLAN?
