Windows Firewall: Blocking Internet Access for an App (Outbound and Inbound Traffic) 🌐⛔💻

By | February 18, 2020

Hello everybody! In this video, I will show you how to set
up Windows Firewall to restrict Internet access for certain applications (that is, how to
block their inbound and outbound Internet traffic). Why would you need it? Blocking inbound traffic allows disabling
unwanted software updates, annoying advertising or saving traffic. Blocking outbound traffic can prevent leaks
of confidential information. Blocking is also good if you want to secure
your child from watching unwanted content or spending too much time playing online games. We will have a look at how firewall works
in Windows 10, but this advice will also work in Windows 8 or 7. To begin with, you should start the firewall
extended interface. To do it:
• go to Control Panel • switch to Large Icons
• click on Windows Firewall In one of the previous videos, I have already
shown you how to open Control Panel. You will find the link in the description • In the firewall window, click on Advanced
Settings. The firewall extended interface has a lot
of settings. Make all changes very attentively, and do
exactly what this guide tells you. If you set certain things wrong, it will result
in lots of problems in the work of your computer. In our channel, you can find a detailed video
on how to set up, enable or disable Windows 10 Firewall. You will find the link in the description • In the left navigation pane, select Outbound
Rules. The system will show all rules created before
– and don’t be surprised to see dozens of entries created by Windows. • In the right pane, click New Rule… • By default, you are suggested to create
a rule for a program, so confirm your choice by clicking Next. • The next step is to show the path to the
executable file of the program to block it. With the example of Opera browser, we’ll
see how Internet connection can be blocked. You can either enter the path to the .exe
file manually or use the Browse button. • If you choose the second option, the system
will automatically replace a part of the path by the environment variable. In our case, the file address is C:Program
FilesOpera45.0.2597.39opera.exe, but the firewall automatically changes the path to
%ProgramFiles%Opera45.0.2597.39opera.exe. An important note: For a number of reasons,
environment variables may be determined incorrectly by the system. If you see that a blocking rule doesn’t
work properly, edit the rule by pasting the full path to the file into the input field. Another important note: In most cases, blocking
the executable file of a program is enough to restrict its Internet access. However, this approach may not work with online
games. For example, if you want to block access to
Minecraft game servers, you should block the corresponding Java application (executable
file Javaw.exe), as the game connects to the Internet via Java. • Confirm the choice of file by clicking
Next. • At the next stage, confirm the choice
Block the connection by clicking Next. • Your next step is to choose when the rule
should apply (by default, all elements are checked). They determine if the rule applies depending
whether the computer is connected to a network which you define as public or private. An important note: If you choose Private and
uncheck Public, it means that the program will have access to resources of the local
network, but it will not have access to the Internet. Let’s suppose you use a laptop at home (in
a network you define as private), at work (in a domain network) and at a cafe (in a
network you define as public). If you want the rule to apply at the cafe,
at work and at home, select all the three options. If you want it to apply only in one of the
three cases, select the corresponding option. If you have doubts, just leave all blocking
options enabled by default. Confirm the choice by clicking Next. • The last step is to give this rule a name. Think about a name that makes sense so that
you will be able to find it easily later. At this point, you can also describe this
rule so you will be able to remember why you created it – after some time. Windows creates a lot of firewall rules automatically,
and all of them have quite fancy names. • To make your rule stand out, name it “Blocking
Opera Browser.” • Close the wizard by clicking Finish. Now there is a new item on the outbound rules
list. You can double-click on it to edit it. For example, you can specify the users for
whom this rule will apply or not, or decide that only a certain protocol should be blocked
– TCP, and so on. Blocking will start as soon as you create
the rule so you don’t have to log off or restart. Start Opera and go to the website,
to make sure the connection is blocked. If you need to disable the blocking, you will
have to return to Windows Firewall advanced settings, left-click on the rule to select
it and then disable or delete it. Use the corresponding items in the right pane
of the Firewall to do it. Similarly, you can set up Inbound Rules. To do it, select the menu line Inbound Rules
and create a rule following the wizard directions. That’s all for now. If you found this video useful, click the

    These things virtually never tell me anything I need to learn … like if I'm defining the scope for opening FTP to a particular remote server, do I need to allow all ports on remote IP or should I define their FTP ports the same as mine? Tutorials are either "Inbound comes from somewhere else" or suggests disallowing Java for literaly everything in order to stop one application.
