How to Configure Windows Firewall Not to Block VPN

Does it block any VPN? The truth is, you might find yourself in the situation where Windows blocks the one you installed, but instead you try another and it doesn’t happen. It can detect it as a problem or that there is a bug in the configuration and it affects that specific application.

What to do to avoid it

What to do so that Windows does not block the VPN? We’ll walk you through the steps if you’re using Windows Firewall. There are many apps available and we couldn’t cover them all, but the steps are similar once you go to the settings of the firewall you have installed.

Create a new rule

The first thing you need to do, in Windows 11 and Windows 10, is go to Start. there you have to look Windows Defender Firewall and you open it. This will take you to the program settings, where you can change some settings to avoid problems or change something you might be interested in.

you have to give Entry rules, which appears in the top left. This will bring you to a new window where many apps that you have installed on the system will appear. The VPN that blocks Windows Firewall should appear there. But what you’re going to do is click new rulewhich appears on the right.

This allows you to create a rule that the firewall should act on. You can block or allow a port, program, etc. In our case, what we want is to allow a VPN through the Windows Firewall, so we mark the option Programwhich is the first that appears in the list, and we click on Next.

Select the program in the firewall

In the next window, as you can see in the image, you will be asked to select the specific application. you have to give Exam and access that program’s route, which in this case would be the VPN.

allow connection

Then you need to login allow connection and press continue. You choose when the rule is applied, give it a name and click Finish. From this moment, you will have created a rule so that the Windows Firewall does not block a VPN that you have installed and that you can browse there normally.

Show blocked apps

Another option you have is to go into Windows Defender Firewall, again from the start menu, and enter Authorize an app or feature through Windows Defender. You will find a window with a list where you will see the apps you have installed.

Allow VPN in Windows Firewall

Just click on the button Modify the parameters and this will allow you to be able to block programs or not. You must click on the button below Allow another application. This, as in the previous case, will open a new window to access the path of this program, which would be the VPN, that you want to authorize.

You just have to give Exam, navigate to the VPN route and select it. You check the box so that the VPN can connect through the firewall, follow the steps and verify that it has access to the Internet. With this, you will be able to see this program in the list of blocked applications, which in this case will appear without blocking.

It is an alternative to the previous option, very simple and fast. Just follow these steps and you can quickly block or allow all programs in Windows Firewall, which can avoid problems if they have no access to the connection and cannot work properly.


In short, as you can see, it is possible that the Microsoft firewall in both Windows 10 and Windows 11 is blocking the VPN. This will make it work properly, you won’t be able to browse the internet through this program, and eventually you will have problems connecting securely.

But this is something you can fix in a simple way. We explained how to authorize a vpn can work through firewall window. There are several options and in both cases you will be able to configure the system to authorize or not an application to function and to have access to the Internet.

It’s something you can change at any time. That is, you might want Windows Firewall to block a VPN you installed at some point. You can create a rule to act when you are connected to a private network, for example. This method will only work if you are connecting to public networks.
