The disclosure is directed to a network gateway device (“gateway”) that provides various network management features, including a device zoning feature in which client computing devices (“client devices”) connected to the gateway are assigned to different device zones. The client devices connected to the gateway form a local area network (LAN) of the gateway, and can access an external network, e.g., Internet, using the gateway. Each of the device zones has a specific set of network access privileges. Different device zones can have different network access privileges and can provide device isolation in the LAN at different degrees.
