    ¿como cerrar puertos en modo invisible ("stealth") en vez de "cerrado"?

    ¿Es posible cerrar puertos en modo invisible ("stealth") por defecto en vez de "cerrado"? He estado trasteando con la contraseña "admin" e incluso he descomprimido el firmware pero no he podido averiguar como hacerlo. ¿Alguien lo sabe?
