hoy comprobé el registro de mi enrutador doméstico y encontré una serie de escaneo de puertos desde diferentes IP:

Nunca he revisado el registro de mi enrutador, pero esta tasa de análisis parece realmente fuera de lo común. También he intentado realizar un escaneo desde mi computadora interna usando mi dirección IP externa:
nmap -sS external.ip.address
y todos los puertos resultaron filtrados. Ahora, ¿es esta la tasa normal de exploración a la que está sujeto un enrutador doméstico? La otra publicación en el foro trataba sobre una sola IP que realiza el escaneo de puertos, pero cada vez me escanean desde una fuente diferente.
