My parent’s have their ONT inside a basement cabinet, where all the house ethernet cables terminate. One of those cables runs up to their office, where the main Wi-Fi router is located (Plume homepod provided by their ISP).
Could they setup their network similar to what’s shown in the diagram where the WAN and LAN traffic passes through the same ethernet cable? If so, are there any specific network settings that should be enabled to prevent any issues?
Very easy if both switches are L2 managed. Ont to switch1 “wan vlan ” Switch1 to rest of house “lan vlan” Switch1 to switch2 “trunk” Switch2 to router wan port “wan vlan” Switch2 to router lan port “lan vlan”
Keep your management traffic off the wan vlan.
