What is firewall process/event logged as : "Windows Operating System" : blocked

Hi,
i need a USB NDIS (tethering USB android to windows) or wifi connexion (with Riftcat or spacedesk) which is : windows <—> android phone direct link via USB or wifi.

Problem : i see the address of my HW (192.168.x.x local) trying to connect each others BUT the COMODO firewall intercept it as “windows operating system” and block it…

How can I unblock it? there is no process name attached just “windows operating system”…

CIS premium 10 personnal
win8.1

thanks

Is it an alert that is shown? Or is it listed as a blocked event in firewall event logs? Can you show your firewall event logs and do you use stealth ports task block incoming connections?

No CIS alert pop-up,

just a “firewall event logged” in the network intrusion

see the attached picture

concerning the incoming stealth port, i’ll look into it, that could be a lead indeed

thanks

That was it! port stealth by default

SOLUTION IS : UN-STEALTH INCOMING PORT

so you’ll get an alert pop up asking yes/no to incoming connection

my thanks to @futuretech
