Llevo un par de semanas con esta versión.

Una de las características del router es que te identifica que equipos están conectados a la red y si lo está por cable o por wifi lo que es una ventaja "contra intrusos".

Esto se realiza con un barrido ARP en la red.

Sin embargo esto puede dar problemas en algunos entornos ya que puede detectarse como una alerta de seguridad.¿Alguien sabe como, o si es posible, desactivar esta característica?
Para algunos es un tanto molesta porque puede enmascarar un barrido ilegítimo. :D
