How to Open a Port in the Windows 7 Firewall. Computers. Operating Systems. Windows 7. How to Open a Port in the Windows 7 Firewall. By Woody Leonhard When you use a firewall — and you should — you change the way your computer communicates with other computers on the Internet.
The firewall blocks all incoming communications unless you open a port in the Windows firewall to let a specific IP communicate with your computer. For example, if you want to play many online games. Most first- time firewallers are overwhelmed by the idea of opening a port. Although open ports are a security threat, sometimes you truly need to open one. Still, you may need to open a port to enable a specific application. For example, when you select the check box to allow Remote Desktop, you’re opening port 3. That’s the security price you pay for enabling programs to talk to each other.
In general, if you need to open a specific port, the documentation for the program (game, torrent downloader, file sharer) will tell you . Click the System and Security link and then click Windows Firewall. You see the main Windows Firewall control window. On the left, click the Advanced Settings link. You see the Windows Firewall sanctum sanctorum. On the left, click Inbound Rules.
Then, on the right, under Actions, click the New Rule link. Windows Firewall shows you the New Inbound Rule Wizard. Select the option marked Port and click Next. The wizard asks you to specify which ports. In the Specific Local Ports box, type the ports you want to open, separated by commas, and then click Next.
For example, in this case, the TCP ports that need to be opened are 4. The wizard takes action and opens those ports to receive data.
Choose Allow the Connection and click Next. The New Inbound Rule Wizard wants to know whether it should apply this rule if you’re connected to a domain network, a private network, or a public network. The safest option is to make it only open on your home network. Check the boxes for Private or any other desired network type, and then click Next. The wizard asks that you give the rule a name and, optionally, a description. Type a name (usually the name of whatever program required the opening).
Click Finish. Your new rule appears in the Inbound Rules list. It takes effect immediately.
Add or Edit Firewall Rule. By using the Software Configuration Wizard (SCW), you can create firewall rules to allow this computer to send traffic to or receive traffic from programs, system services, computers, or users. Firewall rules can be created to take one of three actions for all connections that match the rule's criteria: allow the connection, only allow a connection that is secured through the use of Internet Protocol security (IPsec), or explicitly block the connection.
Important. Firewall rules allow traffic through the firewall but do not secure that traffic. To secure traffic with IPsec, you can create connection security rules. However, the creation of a connection security rule does not allow the traffic through the firewall. You must create a firewall rule to do this, if the traffic is not allowed by the default behavior of the firewall. Connection security rules are not applied to programs or services; they are applied between two computers. The Windows Firewall with Advanced Security snap- in (FW. General tab. Rules can be created for either inbound traffic or outbound traffic.
The rule can be configured to specify the program, service, protocol, or port. As your IT environment changes, you can change, create, or delete rules. Firewall rules are applied in the following order of priority. Authenticated bypass (rules that override block rules). Block connection.
Allow connection. Inbound rules. Inbound rules explicitly allow or explicitly block traffic attempting to access the computer that matches the criteria in the rule. For example, you can configure a rule to explicitly allow traffic secured by IPsec for Remote Desktop through the firewall but block the same traffic if it is not secured by IPsec. When Windows is first installed, inbound traffic is blocked; to allow traffic, you must create an inbound rule. Outbound rules. Outbound rules explicitly allow or explicitly block traffic originating from the computer that matches the criteria in the rule. For example, you can configure a rule to explicitly block outbound traffic to a specific computer through the firewall but allow the same traffic to other computers.

Outbound traffic is allowed by default, so you must create an outbound rule to block traffic. Programs and Services tab. Because Windows Firewall with Advanced Security blocks all incoming unsolicited TCP/IP traffic by default, you might need to configure program, port, and system service rules for programs or services that are acting as servers, listeners, or peers.
Program, port, and system service rules must be managed on an ongoing basis as your server roles or configurations change. Important. The settings for a firewall rule add increasing levels of restriction to the criteria for which connection requests will match the rule. For example, if you do not specify a program or service on the. Program and Services. Therefore, adding more detailed criteria makes the rule progressively more restrictive and less likely to be matched. To add a program to the rules list, you must specify the full path to the executable (.
A system service that runs within its own unique . In the same way, a program that functions like a system service and runs whether or not a user is logged on to the computer is also considered a program, as long as it runs within its own unique .
Caution. Adding programs that host services, such as Svchost. Dllhost. exe, and Inetinfo. Also, adding these programs might conflict with other service- hardening policies on computers running Windows Server 2.
R2 or Windows Server 2. When you add a program to the rules list, Windows Firewall with Advanced Security dynamically opens (unblocks) and closes (blocks) the ports required by the program. When the program is running and listening for incoming traffic, Windows Firewall with Advanced Security opens the required ports; when the program is not running or is not listening for incoming traffic, Windows Firewall with Advanced Security closes the ports.

Because of this dynamic behavior, adding programs to the rules list is the recommended method for allowing unsolicited incoming traffic through Windows Firewall with Advanced Security. Note. You can use program rules to allow unsolicited incoming traffic through Windows Firewall with Advanced Security only if the program uses Windows Sockets (Winsock) to create port assignments. If a program does not use Winsock to assign ports, you must determine which ports the program uses and add those ports to the rules list. Protocols and Ports tab. In some cases, if you cannot add a program or system service to the rules list, you must determine which port or ports the program or system service uses and then add the port or ports to the Windows Firewall with Advanced Security rules list.
On the. Protocols and Ports. If the protocol that you need to add is not in the list, you can select. If you select either the TCP or UDP protocol, you can then specify the local and remote ports to which the rule applies. When you add a TCP or UDP port to the rules list, the port is open (unblocked) whenever Windows Firewall with Advanced Security is running, whether or not there is a program or system service listening for incoming traffic on the port. For this reason, if you need to allow unsolicited incoming traffic through Windows Firewall with Advanced Security, you should create a program rule instead of a port rule. Scope tab. Use the. IP address, a subnet, or a range of IP addresses.
You can use both IPv. IPv. 6 IP addresses. Local IP addresses.
Under. Local IP Addresses. You can further identify when the rule applies to the local computer by specifying an IP address or IP address range to apply the rule to computers that reside in a certain branch of your network. Remote IP addresses. Under. Remote IP Addresses. You can further identify when the rule applies to remote computers by specifying an IP address or IP address range to apply the rule to computers that reside in a certain branch of your network.
