To do so, open the Network & Internet page in the Settings app ( Run -> ms-settings:network-status) and then click on Properties below the network you are connected to. To generate logs for the dropped packets, you must first determine the network profile you are currently on. Note that only those packets will be dropped if the port is listening, which can be checked using the method discussed earlier in the article. These need to be active and then you can check the generated logs for the ports blocked. However, logging in for the dropped packets, which are the packets blocked by the Firewall, is disabled by default in Windows. Logs are an important factor in determining the behavior of the Firewall.

One way to check for any blocked ports is through the Windows Firewall logs. Check if Windows Firewall is blocking ports Check for blocked ports using Firewall logs If the space is empty, it means that it could not find the port you mentioned, or if it did find it, it was not in the listening state. If you find any listings below the command, it means that the port you specified is listening. netstat -ano | find " PortNumber" | find "LISTENING"
Replace PortNumber with the number of the port you are interested in. Alternatively, you can also use the command below to look for a specific network port and check if it is listening or not. You can scroll down the list and look for the port you are interested in.
The ports that have their State listed as Listening are the ones listening to the network traffic. To check for the listening ports on a Windows machine, launch the Command Prompt and then type in the following command: netstat -a -n This is because it could be possible that your application is not receiving any packets since the port that you think is being blocked by the Firewall is not listening at all. Check listening portsīefore checking for blocked ports, let us find out which ports your Windows device is listening to. However, that traffic can still be blocked by the firewall. A listening port simply means that it is receiving some sort of traffic. A listening port is an open port that accepts incoming packets and forwards them to the desired destination application/process.Ī listening port does not mean that it is being allowed by the firewall. By listening, it means receiving information through packets. Check for blocked ports using Command Promptīefore we begin to check which ports are being blocked and which ones are listening, let us discuss what listening means for a computer.īy definition, a listening port is a networking port on which a process or an application listens.Check for blocked ports using Firewall logs.Check if Windows Firewall is blocking ports.
