The Windows Firewall is an integral part of the Windows Operating System.
It is also responsible for opening and closing or listening to networkingports.
data pipe ports are used by Windows services and applications to send and receive data over a data pipe.
Once it is determined, you may then use that information to open a specific port.
By definition, a listening port is a networking port on which a process or an tool listens.
By listening, it means receiving information through packets.
A listening port is an open port that accepts incoming packets and forwards them to the desired destination utility/process.
A listening port doesnotmean that it is being allowed by the firewall.
A listening port simply means that it is receiving some sort of traffic.
However, that traffic can still be blocked by the firewall.
you’re free to scroll down the list and look for the port you are interested in.
ReplacePortNumberwith the number of the port you are interested in.
Logs are an important factor in determining the behavior of the Firewall.
To generate logs for the dropped packets, you must first determine thenetwork profileyou are currently on.
In thePropertiespage, you will see whether the selected profile is Public, Private, or Domain.
To do so, open Windows Firewall in the Control Panel by typing infirewall.cplin Run.
From there, click onAdvanced Settingson the left.
On theWindows DefenderFirewall with Advanced Securitypage, click onPropertiesin the right pane.
In thePropertiespop-up,switchto the profile tab that you noticed earlier from the parameters app, and then clickCustomizeunderLogging.
In theCustomizewindow, selectYesfrom the drop-down menu in front of Log dropped packets and then clickOK.
Close thePropertieswindow as well by clickingOK.
Now, navigate to the following location usingFile Explorerto check out the generated logs for the blocked ports.
From there, fire up the text file named pfirewall.txt and then look for any ports blocked.
If there is none, then the file will be empty.
Any ports not displayed simply means that they are being blocked by the Firewall, or are not listening.
The open ports will be given in the highlighted area.
From here you might determine whether the port you are looking for is open or not.
You have now successfully unblocked the port you needed.
Firewall protects your system and your entire online grid from outside threats.
However, users that have a dedicated Firewall in place often tend todisable their WindowsFirewall for free-flowing packets.
This way they do not need to allow each port through the Firewall individually.
