[drop port scanners] is Working but exactly what is attacking me ??

good days
i get this new router a couple of Mont’s ago and i been learning all what i can.
like 20days ago i set up the router to block port scanners and now i’m pretty amused with the amount of blocked ip’s i have in the list
i was expecting to catch no more than one or two every 3 months but this looks insane

Soo this its mi first time and have questions

  1. this is a normal amount of detections for a 20days period ??
  2. this is for real, there is so many people out there trying to scan what i have open in mi network or i been catching innocent services as port scanners ??
  3. if this is for real, how they know im here, is just random ip attack, or i have a Trojan in mi network, or im in some sort of list or what??

this is just a random 3word factory i don’t have nothing special to hide like to be attacked by Russians and Americans

Just several addresses in 20 days … you are lucky man.
