Hello TechKin

The most typical reason where a port appears as not blocked efficiently by Windows Firewall is when you test using loopback IP for listeners. You will need an external machine to test the inbound filtering of the interface. Is there any special ports that you can mention that are not being filtered effectively?

Dear LimitlessTechnology

I want to configure TCP port, all ports will block but specific ports will open (80,139,443,445,3268,3269,3389,4022,5722). please advice me.

The default action is to block all inbound. So you can simply create one or more custom allow rules.
