Note that: I think was a mistake in the F/W configuration, if possible to share with me your advices. I will put block or allow policy on top and how?

Answer 1

Yes, I'd agree it looks like a mistake so I'd remove the top one from rules. The windows fire wall defaults inbound to blocked.

Answer 2

Dear DSPatrick,
Thanks a lot
I have allowed according to your reference picture but not working this policy.
I will block all posts and then allow specific ports. Tell me about the Windows firewall ports block process, allow port example (80, 53, 3389, 445).

Please note that: when blocking all ports does not working specific allow ports. if possible share docs and you good advice.

Answer 3

As already mentioned and shown in screenshot inbound connections are blocked by default so adding a block rule just adds complications. May want to restore settings and try again.

Hi @PAVZ

You can check the best practices for configuring Windows Defender Firewall and try to replicate it .

Windows Defender Firewall with Advanced Security provides host-based, two-way network traffic filtering and blocks unauthorized network traffic flowing into or out of the local device.
