Basically you do this to prevent a program from connecting to the Internet: From start menu, search for "Firewall" and select Windows Firewall with Advanced Security Choose Outbound Rules from the tree at the left.
Choose New Rule New Outbound Rule Wizard opens. This is really easy now: a. Select Program as rule type. Here, you get to tell Windows what it must do when the application tries to connect to the internet by creating a rule. Since you want Windows to stop the application from reaching the web, you will have to create an outbound rule to enforce the internet blockage.
We will now show you how to do that. Domain is the rule that applies when your computer gets connected to a domain; Private is the rule that applies when your PC is connected to a private network, which could be your home or office network; Public is the rule that applies when your system is connected a public network, such as the WIFI in a coffee shop or airport.
Well, you need Windows to apply the proposed rule for all the profiles, networks, and setups used by the application. Therefore, all the parameters there have to be selected. The rule you just created is supposed to appear on the list under Outbound Rules now.
You can check for it there to confirm things. If you did everything correctly, then Windows will have configured a layer to block all outbound communications from the application for which you want to cut off web access.
In most cases, this is usually enough to prevent the app from reaching the web. Nevertheless, if you want to tighten your grip on the application, then you can go a step further to repeat the same process using Inbound Rules to provide specific instructions to Windows to block all inbound communications for the app. The new rule will be quite identical to the previous one that you already created , but it will govern inbound traffic for the application in view. If Windows is already configured to stop an application from sending out data packets in the first place, then the application is unlikely to receive anything from the web.
In other words, when the rule for Outbound communication is already configured, the one for Inbound communication is probably overkill and not needed. If you want to see how effective the firewall rules can be, then you can run a simple test. You can create an outbound rule to block connections for your browser application to see what happens. After you create the rule, you must open your browser and then try to surf the web by going to a site or page.
If the operation fails and your browser informs you that it cannot connect to the website or internet, then you will know the rule you created has had the effect it should. You are always free to disable or delete a rule — if you change your mind on the blocking of internet access for a specific application. All you have to do is go through the same steps above to open the Windows Defender Firewall with Advanced Security application, locate the rule under the required section Inbound or Outbound list , and then perform the required task on the rule.
Here, we intend to describe alternative methods through which you get to stop an application from reaching the internet. Take certain games, for example. It might seem that all you need to do is create a blocking rule for NameOfGame. In the described scenario, you will need to create a rule to instruct Windows to block connections for Javaw. Or perhaps, you do not even know if the game runs through Java or any similar component, which means you have to start worrying about variables that you failed to account for because you know nothing about them.
