1. A method for protecting a local area network comprising nodes allowing an extension of coverage of wireless communication in order to increase the range of the local area network by coordinating a plurality of access points integrated in the nodes, the nodes being interconnected by means of a backhaul subnetwork, each node of the backhaul subnetwork sending to at least one wireless network, called fronthaul network, wherein the method causing the device to perform:
detecting the connection of a station by means of a cable connection to a network switch included in the local area network, the network switch being connected to the backhaul subnetwork by a cable connection,
establishing secure connections between each node if the connection of the station by means of a cable connection to the network switch is detected,
managing the nodes connected to the network switch with filtering rules applied to the data received by the nodes.
