How to configure Windows Firewall
You can customize most settings of your Windows Firewall through the left pane of the Firewall applet in Control Panel.
1. Turn on or off Windows Firewall
This setting is selected by default. When Windows Firewall is On, most programs are blocked from communicating through the firewall. To turn off Windows Firewall, open Control Panel and click on the Windows Firewall applet. Here, clicking on the Turn Firewall On or Off setting in Control Panel will enable or disable the Windows Firewall on your computer.
2. Block all incoming firewall connections, including those in the list of allowed programs
This setting blocks all unsolicited attempts to connect to your computer. Use this setting when you need maximum protection for your computer, such as when you connect to a public network in a hotel or airport, or when a computer worm is spreading over the Internet. With this setting, you are not notified when Windows Firewall blocks programs, and programs in the list of allowed programs are ignored. When you block all incoming connections, you can still view most web pages, send and receive an e-mail, and send and receive instant messages.
3. Turn off Windows Firewall
Avoid using this setting unless you have another firewall running on your computer. Turning off Windows Firewall might make your computer more vulnerable to damage from hackers and malicious software. Clicking on the Turn Firewall On or Off will let you enable or disable the Windows Firewall on your computer.
4. Block or Allow Programs through the Windows Firewall
By default, most programs are blocked by Windows Firewall to help make your computer more secure. To work properly, some programs might require you to allow them to communicate through the firewall. Here’s how to do that: Click Allow an app or feature through Windows Firewall. If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
Select the check box next to the program you want to allow, select the network location types you want to allow communication on, and then click OK. If you want to allow a program to communicate through the firewall, you can add it to the list of allowed programs. For example, you might not be able to send photos in an instant message until you add the instant messaging program to the list of allowed programs. To add or remove a program to the list, click on the Allow an app or feature through Windows Firewall link to open the following panel, where you will be able to get more details about allowed programs and allow another app to communicate through the firewall.

5. How to open a port in Windows Firewall
You can also block or open a Port in Windows Firewall. If Windows Firewall is blocking a program and you want to allow that program to communicate through the firewall, you can usually do that by selecting the program in the list of allowed programs (also called the exceptions list) in the Windows Firewall. To learn how to do this, see Allow a program to communicate through Windows Firewall. However, if the program isn’t listed, you might need to open a port. For example, to play a multiplayer game with friends online, you might need to open a port for the game so that the firewall allows the game information to reach your computer. A port stays open all the time, so be sure to close ports that you don’t need anymore. Click to open Windows Firewall. In the left pane, click Advanced settings.
In the Windows Firewall with Advanced Security dialog box, in the left pane, click Inbound Rules, and then, in the right pane, click New Rule.
Next, follow the instructions on your screen to its logical conclusion.
