In this article, we are going to be discussing how you can check which ports your device is listening to, and which ones are being blocked by the Firewall. Once it is determined, you may then use that information to open a specific port. Before we begin to check which ports are being blocked and which ones are listening, let us discuss what listening means for a computer.
By definition, a listening port is a networking port on which a process or an application listens. By listening, it means receiving information through packets. A listening port does not mean 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. Before checking for blocked ports , let us find out which ports your Windows device is listening to. 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. To check for the listening ports on a Windows machine, launch the Command Prompt and then type in the following command:.
The ports that have their State listed as Listening are the ones listening to the network traffic. You can scroll down the list and look for 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.

Oh hello, sorry for neglecting the forum. I thought it was dead, yeah disabling the firewall just makes the connection get outright refused.
ISP has already declared that it isn't their side since then, and that's about all the info I have. If you would like I can show you my ipconfig or settings to help find the issue. Tuesday, March 5, PM. Hi, Thanks for your reply.
