Configuring Windows Firewall tutorials

  • Firewall isnít same as antivirus or anti-malware software.

  • Firewall is software or hardware that helps to prevent hacker from getting into your computer through network.

  • You will need separate Antivirus software to protect against Viruses and Anti-malware software to protect against malware.

  • Windows has inbuilt Firewall software, that helps to protect your computer from outside.

  • Firewall blocks all inbound connection except those that are specifically allowed by Firewall.


  • First time when you connect computer to network, you must select a network location.

  • According to network location, Windows 7 will set appropriate firewall and security settings.

  • There are three type of network location.

  • Domain Networks - when Domain controller exist, this option allows you to attach to Domain. Network Discovery is on by default for this mode.

  • Private Networks - Network at Office and Home. You know and trust people and computer on network. This network belongs to HomeGroup. And when you select this mode, Network Discovery is turned On.

  • Guest or Public Network. When you select this mode, Network Discovery is turned Off and no visibility of your computer to others. HomeGroup is not available.

  • You can modify the firewall setting of network location from

  • Xxxx -

  • Windows Firewall -

  • Click Turn Windows Firewall On or Off

  • Select the network location and then make your selection


You can modify following options

  • Block all incoming connections, including those in the list of allowed program.

  • Notify me when Windows Firewall blocks a new Program.

You can customize four settings for each type of network (Public, Private, or Domain). To find these settings, follow these steps:

  1. Open Windows Firewall by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), enter firewall in the search box, tapping or clicking Settings, and then tapping or clicking Windows Firewall.

  2. In the left pane, tap or click Turn Windows Firewall on or off. You might be asked for an admin password or to confirm your choice.


Once done you can do as follows.

  1. Turn on Windows Firewall. This setting is selected by default. When Windows Firewall is on, most apps are blocked from receiving info through the firewall. If you want to allow an app to receive info, follow the steps below to add it to the list of allowed apps. For example, you might not be able to receive photos in an instant message until you add the instant messaging app to the list of allowed apps.

  2. Block all incoming connections, including those in the list of allowed apps. This setting blocks all unsolicited attempts to connect to your PC. Use this setting when you need maximum protection for your PC when you connect to a public network in a Coffee house, Library, hotel or airport. (Blocking happens automatically when you choose the "No, don't turn on sharing or connect to devices" setting for a network). When you block all incoming connections, you can still view most webpages, send and receive email, and send and receive instant messages.

  3. Notify me when Windows Firewall blocks a new app. If you select this check box, Windows Firewall will inform you when it blocks a new app and give you the option of unblocking that app.

  4. Turn off Windows Firewall (not recommended). Avoid using this setting unless you have another firewall app running on your PC.


Firewall Exceptions

  • It is generally safer to add a program to the list of allowed programs than to open a port.

  • If you open a port, you unlock that port, it stays open until you close it whether a program is using it or not.

  • If you add a program to the list of allowed programs, you are unlocking the port but not opening it. The port is open only for communication when a program or the computer requires it.

  • To decrease security risks perform following steps.

  • Allow only program or Port when it is must.

  • Remove Programs from allowed Program list and Close all ports when you donít need them.

  • Finally never allow unknown program to communicate through the Firewall.

  12. Inbound connections - it gives options to control incoming traffic such as

  13. Block (default) - this will block traffic for selected connection.

  14. Block all connection. This will block traffic for all connection.

  15. Allow - this will allow traffic for selected connection.

  20. Settings - Click on Customise button and this will give you customise settings as follow.

  21. Display a notification. When Yes it will display notification to user when a program is blocked from receiving inbound connection. When no, it wonít display notification

  22. Allow Unicast response - By default Yes. When Yes, it will respond to multicast or broadcast network traffic. When you turn it No, it will not respond to other multicast and broadcast. However it wonít affect DHCP (Dynamic Host Configuration Protocol) broadcast but it will affect other protocol broadcast such as NetBIOS, SSDP and WSDAPI.

  23. Logging:- Click on Customize to configure

  24. Name:- You can specify Firewall Profile Log file name and path. Default log file path is %systemroot%\System32\logfiles\firewall\pfirewall.log

  28. Windows Firewall with Advance security Rules

  29. Rules are collection of conditions that define which traffic will be allowed, Blocked or secured with firewall.


There are three types of rules.

  1. Inbound Rules.

  2. Outbound Rules.

  3. Connection Security Rules.


Inbound Rules

  • As name suggest Inbound Rules explicitly allows or block traffic that match ruleís condition.

  • When you install Windows, Windows Firewall blocks all unsolicited inbound traffic. To allow unsolicited inbound traffic you have to create inbound rule.


Outbound Rules

  • Windows Firewall allows all outbound traffic. Outbound rules explicitly allow or deny traffic originated from current computer.

  • Because outbound traffic is allowed by default, you typically use outbound rules to block network traffic that you do not want.


There are four different types of Inbound and outbound rules.

Program rules -

  • This rule control traffic for a program

  • This rule is useful when you are not sure about the port number or other settings required.

  • You have to specify The Program path that is executable .exe file location,


Port Rule

  • This rule allows connection based on TCP or UDP port number over which computer is trying to connect.

  • You can specify selected port or port numbers in range,


Predefined Rules

  • Windows 7 gives bunch of predefined Rules such as BranchCache Content Retrieval, Core networking, Remote Desktop, Windows Remote Management and so on.


Custom Rules

  • You can specify custom rule for connection based on condition that other types of firewall rules do not cover.

  • You need to specify Program name, Protocol Type, Port number, Local and Remote port, Local and Remote IP Address and so on.

  • Specify action whether to allow it, allow if connection is secure or block it.

  • Specify Profile Domain, Private or Public where rule apply.

  • Finally give name to rule.

  • Connection Security rules

  • Connection security rules involve the authentication of two computers before they begin communications and the securing of information sent between two computers.

  • Connection Security Rules uses IPsec (Internet Protocol security) to secure traffic while it crosses the network.

  • IPsec achieve connection security by using key exchange, authentication, data integrity and data encryption.

  • Connection security rules are discussed in detail in later part of this video.
