Protect a few ports from local network. Is my Firewall rule secure?

Recommended Posts

I'm trying to reject (ESET should notify and ask me first) access for some ports (80,443,8080,22, and others) from my local network. -for the whole internet it's already protected from Windows Firewall and my router settings and all access are blocked. But for local network, it's opening and allowing.

I did the following:

  • 1) Created a rule in the firewall.
  • 2) Set the settings as the following:
    • 2.1) Direction: In
    • 2.2) Action: Ask
    • 2.3) Protocol: TCP
    • 2.4) Local window > Ports: 80,443,8080-8082,21-23
    • 2.5) Remote window > Zones: Private addresses

It is working great as expected (everyone in the local network trying to access any of these ports; the app will notify me whether to allow or reject it). But, the problem is, sometimes when I first logon to Windows, it asks me, and from time to time (idk when it happens, but randomly i think), it asks me. That's the first thing.

The second thing is, is this rule really secure? or did i do something unnecessary and put my device in danger?
