Ports unfiltered with Kaspersky Firewall

[normal.guy]

Hi-
I am running Kaspersky Total Security version 21.3.10.391. My OS version is Windows 11 21H2. I just discovered an issue with Kaspersky Firewall that I need clarification on. Kaspersky doesn't seem to be filtering a lot of ports on a port scan, even with Network Attack Blocker and Firewall turned on. Certain points are filtered, but others aren't. It is seemingly random. I'd appreciate it if anyone could provide a reason why this is happening and if this poses a threat to my network.

Hi @normal.guy, 

You can review the ports which are scanned via Settings -> Network settings -> 'Monitor selected ports only'.

You can enable 'Monitor all network ports', more information here.
