Reporting Services Report server applications and published reports are accessed through URLs that specify an IP address, port, and virtual directory. If Windows Firewall is turned on, the port that the report server is configured to use is most likely closed. Indications that a port might be closed are receiving a blank page when you attempt to open the web portal from a remote client computer, or a blank Web page after requesting a report.
To open a port, you must use the Windows Firewall utility on the report server computer. Reporting Services will not open ports for you; you must perform this step manually.
By default, the report server listens for HTTP requests on port 80. As such, the following instructions include steps that specify that port. If you configured the report server URLs to use a different port, you must specify that port number when following the instructions below.
If you are accessing SQL Server relational databases on external computers, or if the report server database is on an external SQL Server instance, you must open port 1433 and 1434 on the external computer. For more information, see Configure a Windows Firewall for Database Engine Access.
For more information about the default Windows firewall settings, and a description of the TCP ports that affect the Database Engine, Analysis Services, Reporting Services, and Integration Services, see Configure the Windows Firewall to Allow SQL Server Access.
Prerequisites
These instructions assume that you already configured the service account, created the report server database, and configured URLs for the Report Server Web service and the web portal. For more information, see Manage a Reporting Services Native Mode Report Server.
You should also have verified that the report server is accessible over a local Web browser connection to the local report server instance. This step establishes that you have a working installation. You should verify that the installation is configured correctly before you begin opening ports. To complete this step on Windows Server, you must have also added the report server site to Trusted Sites. For more information, see Configure a Native Mode Report Server for Local Administration (SSRS).
Opening Ports in Windows Firewall
To open port 80
-
From the Start menu, click Control Panel, click System and Security, and then click Windows Firewall. Control Panel is not configured for ‘Category’ view, you only need to select Windows Firewall.
-
Click Advanced Settings.
-
Click Inbound Rules.
-
Click New Rule in the Actions window.
-
Click Rule Type of Port.
-
Click Next.
-
On the Protocol and Ports page click TCP.
-
Select Specific Local Ports and type a value of 80.
-
Click Next.
-
On the Action page click Allow the connection.
-
Click Next.
-
On the Profile page click the appropriate options for your environment.
-
Click Next.
-
On the Name page enter a name ofReportServer (TCP on port 80)
-
Click Finish.
-
Restart the computer.
Next steps
After you open the port and before you confirm whether remote users can access the report server on the port that you open, you must grant user access to the report server through role assignments on Home and at the site level. You can open a port correctly and still have report server connections fail if users do not have sufficient permissions. For more information, see Grant user access to a report server.
You can also verify that the port is opened correctly by starting the web portal on a different computer. For more information, see The web portal of a report server.

How to open firewall port on Windows 10
If you have an app getting blocked by the firewall, here are the steps to open the port through the Microsoft Defender Firewall on Windows 10.
Mauro Huc
@pureinfotech
On Windows 10, the built-in firewall (also known as the “Microsoft Defender Firewall” or “Windows Firewall”) is a powerful feature that protects your computer and data from threats from outside trying to get in and from those inside trying to get out.
A firewall works as a gatekeeper and blocks all unnecessary network ports. Every time an app or service tries to communicate outside your device, it checks if there’s a specific rule in the database to allow or deny network access. You’ll see a prompt to identify and grant or deny permission if it can’t find a rule.
Sometimes well-known applications (for example, SQL Server and QuickBooks) will not work as expected because they’re getting blocked by the Microsoft Defender Firewall. When this happens, you’ll need to manually create a rule to allow them to access the network.
This guide will teach you the steps to open a port to allow an app to communicate outside the network using the built-in firewall on Windows 10.
- Open firewall port on Windows 10
- Close firewall port on Windows 10
Important: Before proceeding, check the app support documentation to know the ports and protocol type you need to open. Also, you can quickly confirm if you need to open a port by temporarily disabling the firewall, and if the app works with the firewall disabled, it indicates you need to create a new rule.
Open firewall port on Windows 10
To open one or more ports in the Windows firewall, use these steps:
-
Open Windows Security.
-
Click on Firewall & network protection.
-
Click the Advanced settings option.
-
Select Inbound Rules from the left navigation pane.
-
Under the “Actions” section, click the New Rule option in the right pane.
-
Select the Port option.
-
Click the Next button.
-
Select the appropriate protocol (TCP or UDP) depending on the application. (Usually, the option is TCP.)
-
In the Specific local ports setting, type the port number.
Quick note: If the app requires multiple ports open, you can type as many as you need as long as you separate each one with a comma (4500,4600,5000).
If you need to specify a port range, then you can use a hyphen (-). For example, 3000-3100. -
Click the Next button.
-
Select the Allow the connection option. (Using the same step, note that you can block the connection.)
-
Click the Next button.
-
Select the network type to apply the rule. (Usually, you want to leave this option with the default selections.)
-
Click the Next button.
-
Type a descriptive name for the rule—for example, My Inbound Rule for QuickBooks.
-
Click the Finish button.
After you complete the steps, inbound connections will be allowed for the app through the port you open in the firewall.
Open outgoing port in Microsoft Defender Firewall
If the app needs a specific outbound port, you can use the same instructions, but instead of selecting Inbound Rules on step No.
4, you would choose the Outbound Rules options. Here’s how:
-
Open Windows Security.
-
Click on Firewall & network protection.
-
Click the Advanced settings option.
-
Click on Outbound Rules in the left navigation pane.
-
Under the “Actions” section, click the New Rule option in the right pane.
-
Select the Port option.
-
Click the Next button.
-
Select the appropriate protocol (TCP or UDP) depending on the application.
-
In the Specific local ports setting, type the port number.
-
Click the Next button.
-
Select the Allow the connection option.
-
Click the Next button.
-
Select the network type to apply the new rule.
-
Click the Next button.
-
Type a descriptive name for the rule.
-
Click the Finish button.
Once you complete the steps, outbound connections will be allowed for your application through the port you open in the Windows firewall.
Close firewall port on Windows 10
To close the port in the Microsoft Defender Firewall, use these steps:
-
Open Windows Security.
-
Click on Firewall & network protection.
-
Click the Advanced settings option.
-
Click on Inbound Rules or Outbound Rules from the left navigation pane, depending on where you open the firewall port.
-
Select the rule you want.
-
Under the “Actions” section, click the Disable Rule to close the port while keeping the rule.
Or click the Delete Rule option to close the port and remove the rule from the firewall.
After you complete the steps, the app or service will no longer have access to the network or internet because it’ll be blocked by the Windows firewall.

Open and Change Firewall Ports In Windows Server 2019
Managing your network traffic is essential in securing any device that handles your workloads. One of the primary tools in doing so is a firewall. The Windows operating system (OS) comes prepackaged with the Windows Defender Firewall to assist with this task.
A firewall is an application that will monitor network traffic on an interface, compare it with a set of rules, and decide if that traffic is allowed or not.
When you initially set up your server or add any new applications requiring Internet access, configuring your firewall is necessary to allow incoming traffic.
Whether you are configuring your cloud firewall, a hardware firewall, or the one included in the OS, securing network traffic is essential. This article will cover how to open a port in your Windows firewall, close a port, and allow traffic for specific programs.
Requirements
These are the requirements for opening a port or allowing access to applications you configure:
- The port number or application you want to open on your Windows firewall.
- The protocol the application will use — connectionless (UDP) or connection-oriented (TCP).
- The physical path to the application’s executable (if you will be creating a program-based rule).
Typically, your software vendor will provide this information to you if you do not have it. To assist, here is a brief list of common protocols and their associated port numbers.
- File Transfer Protocol (FTP) Data Transfer — 20
- File Transfer Protocol (FTP) Command Control — 21
- Telnet — 23
- Simple Mail Transfer Protocol (SMTP) — 25
- Domain Name System (DNS) — 53
- Hypertext Transfer Protocol (HTTP) — 80
- Post Office Protocol (POP) — 110
- Internet Message Access Protocol (IMAP) — 143
- Remote Desktop Protocol (RDP) — 3389
- Hypertext Transfer Protocol Secure (HTTPS) — 443
- Microsoft SQL (MSSQL) — 1433
Open and Change Firewall Ports In Windows Server 2019
How to Access and Check the Windows Server Firewall Settings
Step 1: Access the Windows Firewall Management Console
You can view various settings from the management console, such as the Overview of the Domain Profile and multiple wizards to execute tasks within the Windows Firewall.
2. Click the Search icon on the bottom-left of the taskbar and type firewall.
3. Click on Windows Defender Firewall with Advanced Security. This action opens the Windows Firewall Management Console.
Step 2: View and Configure Inbound Rules in the Console
1. From the left-hand navigation, click Inbound Rules to expose the Inbound Rules pane on the right.
2. Click the Enabled column at the top to sort your rules by status until the value of Yes is at the top. Make a note of the preconfigured rules.
Note:
The rules created by Liquid Web allow access to your server. Disabling or editing these rules could cause network disruptions or prevent support from assisting you.
Open a Port in Windows Server Firewall
1. Open the firewall manager again.
2. Click Inbound Rules from the left pane to reveal the Inbound Rules pane on the right.
3. Click New Rule in the right-hand pane to open the New Inbound Rule Wizard.
4.
In the New Inbound Rule Wizard, under the Rule Type section, select the Port radio button and click Next.
5. In the Protocol and Ports section, select TCP or UDP. Next, select the radio button for All local ports or Specific local ports. For this tutorial, choose Specific local ports and enter the corresponding port number. If listing multiple ports, split them with a comma. Once completed, click Next.
6. In the Action section, select Allow the connection (or choose the setting for your requirements) and click Next.
7. In the Profile section, select all appropriate profiles for when this rule applies and click Next.
8. Finally, give your new rule a descriptive name so that it is easy to find later, and click Finish.
You should now be able to see your new rule created in the Inbound Rules pane and establish connections to your server with the configured port if a program or service is listening on that port.
Close a Port in Windows Server Firewall
If you need to close a previously opened port, find and disable the rule that opens the port using these steps.
1. Open the firewall manager.
2. Click Inbound Rules from the left pane to reveal the Inbound Rules pane on the right.
3. Click the Enabled column at the top to sort your rules by status until the value of Yes is at the top.
4. Locate the rule for the local port you would like to close.
5. Right-click on the rule and select Disable.
The Inbound Rule is disabled, and access to the port is restricted.
Open a Port for a Specific Program in Windows Server Firewall
Some applications use more than one port or more than one protocol when communicating over the Internet. You can create a Program Rule Type in Windows Defender Firewall to simplify allowing traffic for these programs. These rules also add additional security, as the ports a program typically listens on are not open unless the defined program is running.
Here are the steps to open a port for a specific program.
1. Open the firewall manager.
2. Click Inbound Rules from the left pane to reveal the Inbound Rules pane on the right.
3. On the Inbound Rules pane, click New Rule to open the New Inbound Rule Wizard.
4. In the New Inbound Rule Wizard under Rule Type, select Program and click Next.
5. Under the Program section, select the radio button for This program path and click Browse.
6. Locate the executable for the program you wish to open the port for, select it, and click Open.
7. Verify the path location is correct and click Next.
8. In the Action section, select the radio button for Allow the connection and click Next.
9. In the Profile section, select all appropriate profiles for your requirements and click Next.
10. Give your new rule a descriptive name to find it easily later, and click Finish.
You should now be able to see your new Windows Firewall Program Rule. Ensure the program you selected is running, and you can access it remotely.

Configuring a firewall for reporting server access — SQL Server Reporting Services (SSRS)
E-mail address
- Article
- Reading takes 2 minutes
Reporting Services report server applications and published reports are accessed using URLs that consist of an IP address, port number, and virtual directory name.
If Windows Firewall is enabled, the port on which the report server is configured is most likely closed. This usually results in a blank web page being displayed when a remote client computer accesses the web portal, or a blank web page is displayed when a report is requested.
You can open the port using Windows Firewall on the report server computer. Reporting Services does not automatically open ports, you must complete this step manually.
By default, the report server listens for HTTP requests on port 80. The following step-by-step instructions configure the port. If the report server URLs are set to a different port, you must specify the port number when following the instructions below.
When accessing SQL Server relational databases on external computers, or if the report server database is located on an external SQL Server instance, you must open port 1433 and 1434 on the external computer. For more information about Windows Firewall, see Configure Windows Firewall to Access the Database Engine. For more information about default Windows firewall settings and a description of the TCP ports that affect the Database Engine, Analysis Services, Reporting Services, and Integration Services, see Configuring the Windows Firewall to Allow Access to SQL Server.
Prerequisites
The following instructions assume that you have created the Report Server database, configured the service account, and configured the Report Server Web Portal and Web Service URLs. For more information, see Managing a Reporting Services Native Mode Report Server.
In addition, you must check that the report server instance is accessible from a web browser over a local connection. This step is required to verify that the installation works. Before proceeding with opening ports, you need to verify that the installation is configured correctly. To complete this step on Windows Server, you will also need to add the report server to Trusted Sites. For more information, see Configuring a Native Mode Report Server for Local Administration (SSRS).

How to open ports windows 10 2021
Windows Firewall is designed to protect your computer from potential threats and malware. It blocks access to the Internet for applications that may pose a threat to the integrity of the system.
As you know, programs use ports to communicate with their servers and the Internet. Basically, they are opened automatically by applications that get instant access to the network. But sometimes they need to be opened manually, that is, the application will be denied access to the Internet while they are closed. Let’s learn more about how to open specific ports in the Windows 10 firewall.
How do I open ports through the Windows 10 Firewall?
This method is not the easiest, but absolutely any Windows user can perform it. Additional installations are also not required.
- Go to the control panel. This can be done in different ways, we will open this system tool through the search box by entering the appropriate phrase into it.
- Open System and Security -> Windows Defender Firewall.
- In the menu column on the left, select the “Advanced Options” item.
- Now we need to click on “Inbound Rules” and then click on the “Create Rule…” button.
- The wizard for creating new rules will start, in the first menu of which we select the “For port” item.
- Then the user must decide which protocol will be used in this rule — TCP or UDP, and also specify the port number (80 (8080), 22, and any other.
- Select the parameter numbered «1» — «Allow connection «.
- Now mark the desired type of network connection (you can leave all options).
- The final step is to come up with a name for the new rule (its number is suitable: 80, 22), and also write a short description that may help in the future.
At the sixth step, you can select the “All local ports” option and then you will not need to find out the port number you need. But we absolutely do not recommend doing this … And here’s why!
Important! Opening any additional ports is a threat to the security of your Windows 10. The fact is that data is exchanged through these ports, both global (via the Internet) and local (requests for third-party programs installed on the PC).
If you need to do this for the game, then in most cases it does not pose a danger and errors to the system … The main thing is to follow the instructions clearly.
Initial check
You can first check which ports are already open.
To do this, you can use the command line. Let’s launch it. In this operation, it is better to use the standard cmd line, and not PowerShell. Press the key combination Win + R and write the command cmd.
In the line, write the command netstat –aon | more. Press Enter — and a list of all active Windows ports appears in front of us.
The Listening value indicates that the port is listening. The Established port state indicates that the connection between the two points is established. There will also be Time Wait (timeout) and Close Wait (waiting for the connection to close).
Opening ports in an antivirus program
Following this instruction, you can quickly open the desired port without creating a new rule. But you will have to install third-party antivirus software. We will consider everything using the example of Kaspersky antivirus (official site).
- Run this program and in the window that appears, click on the “Gear” icon in the lower left corner.
- In the settings, select the “Network settings” item.
- Find the sub-item “Controlled ports”. Now select the “Monitor only selected ports” option and click the “Select” button.
- Click on the “Add” button. In a new window, set the name of this port, and then select its number. For example, the same 8080… The status, of course, is “Active”.
- Reboot your system for all changes to take effect.
Purpose of ports
Technically speaking, a port is a network transport protocol parameter that provides independent packet data transfer for different programs running on the same host. In simple terms, this is like the apartment number from the address of a paper letter — without specifying this number, the message (data packet) simply will not be delivered to the addressee. It is important to understand how to open a port on a Windows 10 computer, since the updated interface and wide functionality of the system makes this procedure difficult.
Using a firewall
First, let’s look at a detailed algorithm of actions that will help you understand how to open a port in the Windows 10 firewall, and then we will mention the main values \u200b\u200bfor this network parameter and what they are for.
- Go to «Windows Firewall» through the control panel.
- Select the item «Additional parameters» and go to the subsection of the rules, which is indicated in the screenshot (1). As the name implies, a complete list of rules for incoming connections will open. To add your own rule, you need to click the corresponding button (2).
- Since we are talking about opening a new port, you need to select this type of rule in the window that opens and continue creating by clicking «Next».
- In the next window, select the connection protocol (TCP/UDP) and specify the specific values that will be opened. The setup wizard in the form of an example (below the line where the number is entered) shows how to enter a list or range of values, if it is a large number of them, with each number in turn.
You should not check the box to open all local ports. This action will lead to the formation of a huge gap in the protective screen of the operating system and will allow anyone to connect to the computer.
- In the next window, you need to select the option for the action to be taken with the specified values. In our case, they need to be allowed, but they can also be added to the “For a secure connection” category or blocked.
- Clicking «Next» again will lead to a window where you will need to select the local network profiles for which the created rule will be activated.
- Then all that remains is to enter a name for the rule and confirm its creation by clicking the «Finish» button.
Naturally, immediately after the entire creation procedure, the new rule will add to the list for incoming connections.
A completely identical algorithm is used when working with outbound connection rules that will be created from Windows 10 used by the owner of the computer.
We solve the problem through the router settings
You can do the so-called port forwarding in the router settings. Depending on the model of your gadget, the names of the items may differ.
- In the address bar of any browser, enter “192.168.0.1” (instead of “0” it can be “1”).
- Log in to the settings by entering your login and password. Default: «admin — admin».
- Now open the section “Internet” -> “Port Forwarding”.
- Select all characteristics (port number, TCP/UDP protocol), such as in creating a rule through a firewall. Enter the IP address of your PC.
- Add a new rule for the router and save everything.
Close the browser window. If there are errors in the Internet, you will need to reboot the router.
The main ports and their purpose
Speaking about how to create ports, one cannot but tell what they are and what certain values are intended for. After reading this information, it will be possible to tell not only how to create a rule for a specific type of connection, but also how to open port 80 for Windows 10 (or any other), if necessary.
| No. | Purpose |
| 21 | Required for working with FTP servers. Allows not only to connect to the server and view data on it, but also to upload/download them. |
| 22 | This is the setting for the SSH network protocol, which is responsible for remote OS management and makes it possible to transfer files between different devices. |
| 23 | Helps to implement a text-based network interface aimed at the same external control of the system. |
| 25 | The basic SMTP mail protocol, which, as it becomes clear, is needed to send messages over the network. |
| 53 | Required for the DNS (Domain Name System) to work, which is actually the tip in creating the name of a particular network IP address. |
| 79 | Finger network protocol that allows you to get information about all users on a remote computer. |
| 80 | Indicates the existence of a virtual server on a particular machine. |
| 110 | The POP3 protocol responsible for transferring messages between a mail server and a computer. |
| 111 | Sun RPC is a system through which procedures can be called remotely. |
| 119 | NNTP — Responsible for communication between newsgroup members. |
| 139 | NetBIOS is a generally accepted protocol designed for local networks to which a variety of IBM / PCs are connected and the manufacturer does not affect their joint functioning at all. |
| 443 | You should know how to open port 443 on Windows 10, because it is responsible for the operation of the HTTPS protocol, which is the main encryption for modern websites. |
| 513 | The rLogin protocol and, again, remote access to UNIX systems, which can be obtained by any users of similar UNIX systems. |
A complete list of parameters for creating rules
Finally, there is a category of ports that you should not forget about, but the most reasonable way is to select them in the list given at this link: https://ru.
wikipedia.org/ wiki/List_of_TCP_and_UDP_ports. The table shows all possible options and if you need to know, how to open port 25565 on Windows 10 , it immediately becomes clear that we are talking about setting up a Minecraft game. It also contains all the values for various system functions and most popular installed applications.
Naturally, the settings of all applications and video games are individual, and therefore you should be careful with the firewall service. There is a risk that the next created rule will lead to an intrusion into the operating system with its subsequent disabling. Or, incorrect configurations will cause some applications and video games to stop functioning.
Why you need port
When you use the Internet, you both send and receive data from the network. Figuratively speaking, tunnels are created between your computer and a modem or router responsible for transmitting and receiving information. To create a new tunnel, you need to open a port.
Each tunnel has its own characteristics and characteristics, depending on which port is deployed.
The system has predefined port numbers. With the help of them, it is determined what this port is responsible for. For example, seeing the number 443, the system will understand that the enhanced security protocol is being used. Port number 80 is responsible for the HTTP connection, and it is used every time you connect to the Internet, since almost all sites work using the HTTP protocol. For a more complete list of the most commonly used ports, see the «List of ports and their tasks» section.
Checking the status of ports
To find out what state all ports are in (open, closed, in use or disabled), you can use the built-in tools of Windows 10.
Online service 2ip.ru
— the 2ip.ru service, designed to display various useful information on a computer, including network ports.
To visit the service:
- Open an Internet browser and follow the link https://2ip.
ru/check-port. - In the free line, enter the port number, for example, 25565 and click «Check».
- As you can see in the screenshot above, tunnel 25565 is already busy. Thus, you can check any channel for busyness.
The advantages of this method are its availability and no need to install separate software. But it only serves as an addition to the previous two options.
When should ports be opened?
Many programs and games that use an Internet connection only work with certain protocols. By default, the Windows 10 operating system protects the computer from free access to any ports for security purposes. The same can be said about anti-virus software (does not apply to the standard Windows Defender) and a router. Therefore, the user must independently allow access to a particular port when it is not available. Below is an example of a forwarding for the Minecraft online game.
How to get into the Windows firewall settings
The built-in firewall setting is located in the Control Panel, System and Security section.
In Windows 8 and 8.1, you can use the desktop item — Search. You need to start typing the word «Firewall» and the system will display a link in the results. Another quick and convenient way to quickly get into the Firewall settings is to press the key combination Win + R:
In the open line, write firewall.cpl, press the OK button.
What is a “Port” and why is it needed
The main task of a personal computer is to process information using a variety of programs for various purposes. Most programs access their own server to receive and send data packages, such as regular updates or individual files (file sharing). Information is transmitted through a specific channel — a port. Each port (tunnel) has its own number, which is an identifier and determines its purpose. For example, to use the remote desktop of another computer, you need to check the status and, if necessary, open port 3389.
When installing a new game or other software, by default, the tunnel is automatically checked and connected to the server.
Windows Firewall displays a window asking you to allow or block the activity of this program on the network. If this is not observed and the software does not want to connect, you need to open its port on the computer.
Verification
Two methods are usually used for verification — the 2ip.ru website and the command line. Let’s figure out how to check the port through the site:
- Open the link https://2ip.ru/ and go to the Port Check section.
- Enter the number you are interested in and click on the «Check» button.
To run the scan via the command line, you need:
- Launch the application via search.
- Type the command «netstat -a» and press Enter.
- On the screen you will see a list of ports that are currently open.
How to check if the required port is open or closed on windows
The easiest option is to use a free ONLINE service that checks their availability.
Sites such as 2ip.ru or PortScan.ru can easily help you with this.
If you want to check availability and open them on windows, you need to start the telnet service. To do this, in the explorer you need to go along the path: «Computer»? «Uninstall or change a program»
in the window that opens, select «Turn Windows features on or off» in the left column.
In the «Windows Components» list about and «Telnet Client». Then go to the windows command line, you can do this by pressing «+ R» and typing cmd in the line.
Once in the console, enter telnet 127.0.0.1 110 (127.0.0.1 is the local address of the computer, 110 is the port). If the connection is established successfully and no error message appears, then everything is fine.
In case an error message appears, the first thing to do is to check the firewall, and the installed firewall, perhaps the problem is in them. But remember, if everything is in order on the computer, this does not mean that everything is configured correctly on the router too!
Opening port 80
This channel is the main channel for data transfer between the PC and the World Wide Web using the http protocol.
Port 80 cannot be freed using the method described above, since it is controlled by the special http.sys system driver.
This time we turn to the command line.
- Open the command line in a known way and enter the command «netsh http «add iplisten ipaddress=::» (without quotes) and press «Enter».
- The second step is to make a change to the hosts notepad file located in the path «C:WindowsSystem32driversetchosts». In it, you need to add the entry «127.0.0.1 local» (without quotes). After that, restart your PC and check the status of port 80.
- If this does not help, then open the menu «Start / Control Panel / Programs / Programs and Features» and click on «Turn Windows features on or off.»
- Disable IIS services by unchecking all items.
We restart the computer and again check the availability of port 80.
Open a port in the firewall using netsh
Netsh is a command-line utility that allows you to change many network-related settings.
1. Open command prompt as administrator: one way is to type cmd in the search bar => right click on “Command Prompt” and select “Run as administrator”.
2. To open the port, use the command netsh advfirewall firewall add rule name=”Open Port 9996” dir=in action=allow protocol=TCP localport=9996 Instead of Open Port 9996, you can write any name for the rule, instead of 9996 at the end of the command, write the port number you want to open.
To delete the created rule, you need to use the command netsh advfirewall firewall delete rule name=”Open Port 9996” protocol=TCP localport=9996
Summarizing the above
Windows 7 and 10? To do this, we have chosen and described the most popular ways to solve this problem with examples.
Summing up, we have compiled a brief description of each method separately.
The standard Windows tools were not the most convenient to manage, however, they provide a sufficient amount of information about the processes and the ports they use.
Working with the Firewall and the console is quite simple and after our example, you will be able to repeat all this on your own computer.
CurrPorts displays maximum data about ports and processes, allows you to delete (release) them, but does not allow you to open new ones. In our opinion, the software is perfect for tracking potential threats from the Web and eliminating them.
Despite the lack of a Russian-language interface, UPnP Wizard is very practical and can both create and release ports. The only limitation is the requirement for the router to support a UPnP interface. We believe that this option is the most convenient for general use.
The 2ip.ru resource is very useful, as it almost instantly displays the status of the port specified by the user. It has no other functions and therefore it should be used as an addition to a standard program or firewall.
Connection to online services occurs using special ports that the system must open when user applications access them.
Most often, gamers and those who download files using torrent clients face the need to solve the problem of how to open ports on Windows 10. Modern programs configure the system on their own, but some applications do not have this feature built in.
What do we discover?
A port is a specific numeric code that allows the system to communicate with hosts from the Internet. This is a kind of path that helps the necessary data to check and get from a remote server exactly to your computer, exactly at the address.
Some applications do not require opening an additional connection, since it is already open. But for some closed resources, games (for example, Minecraft), you have to do this manually.
Disabling the firewall
Windows Firewall itself can often block many connections, so in some cases you can simply try to disable it. However, if you do not have any antivirus installed on your computer, then using the Internet with a disabled firewall can be dangerous for your computer.
To disable the firewall, you just need to go into it, select the item «Turn Windows Firewall on or off», in the settings, put the markers on «Turn off Windows Firewall» and click «OK».

How to open and configure a port on a Windows 10 computer?
Let’s start with basic knowledge of what a port is and how to open them on windows 10 — imagine a tunnel through which two points interact, to enter, each of them needs an open door, so port is a point, and the door is its open or closed status. As a rule, network exchange is required in games, various network distributions, etc. Moreover, you have probably heard such a thing as a firewall — built-in protection — a firewall that is able to protect the system — like a stone wall of a house, and each new opening of a port stings it.
Checking ports
Before we start opening ports, let’s check which of them are already open, there are special programs for this, but for now we will use the built-in Windows tools.
Let’s get started.
- Run cmd as administrator [Win]+[X] → «Command Prompt (admin) → [enter]
- Type «cmd» without quotes → OK.
- We also drive in without using quotes “netstat –aon | more» → [input]
In the command, we indicated that we need information about the state of network connections and listening ports with parameters: a — all connections and waiting ports; o – show process ID; n — show the number and address of the port in numerical terms; more — page output.
In such a simple way, we learned how to look at the ports, we get the answer in tabular form, by ports, now about decryption:
- “LISTENING” — the port is listening;
- «ESTABLISHED» — point-to-point connection established;
- «TIME WAIT» — response time exceeded;
- «CLOSE WAIT — connection waiting to be closed.
A little later, in more detail using several positions as an example, we will consider how to open a port in the firewall in windows 10 in a few minutes and without much difficulty.
We remind you that the more holes in the protection, the more vulnerable you are.
Who is busy with what …
We figured out where you can find ports on windows 10 and how to figure out if they are open or in standby mode, now let’s see which program uses open ports, maybe we don’t need it. Recall the screenshot in which the list with the PID numbers of the text_19 process/screenshot_03
Let’s see who is this mysterious under PID 4
- Go to the task manager [Ctrl] + [Shift] + [Esc] → «Details» → for convenience, click on the «Process ID» column — put in order
- Right click on «4» → «Open file location»
- Our «NT Kernel & System» file is a system program that is responsible for processing third-party software, it includes game engines, updates, etc. If problems start in the above applications, “NT Kernel & System” starts to hang up the processor.
443 HTTPS
One of the popular ports and are used in secure game channels and cloud services, in the address bar, pay attention to the beginning, if https:// is present — HyperText Transfer Protocol Secure, it says that it works through 443 port – supports encryption, increasing security.
When asked how to open a port on a computer in windows 10 on your own, it’s quite simple, below are step-by-step instructions.
- [Win]+[R] → type «firewall.cpl» → OK
2. In the window that opens «Windows Firewall» → «Advanced settings»
3. «Inbound rules» → on the right «Create rule»
9 «Rule type 4». For port «
5. At this point, we show how to open port 443 on windows 10, when choosing the Protocol, we specify TCP and enter our port.
Pay attention to the block on the right, there is a newly opened HTTPS -443.
80 HTTP (previously WWW)
Needless to say, thanks to this port we are all online, it accepts the HyperText Transfer Protocol on the web server. You can open port 80 in windows 10 in the same way as 443, but at step 6 — enter our 80 and also select TCP.
As you can see, with simple manipulations and in just a few clicks, you can configure ports.
Opening ports for games
Network games actively use ports, and of course there is often no way to start or no access at all, so how to open ports on windows 10 for games. Follow the same instructions above to step 4.
- «Rule type» → «Program» → «Program path» → «Browse» — select the location of the executable *.exe file.
Each step in the screenshots in detail.
Set up for torrent
Already proven method, repeat steps up to 6, and specify the following: » → «Defined local ports: 33033».
- Before the naming step, everything is identical, we give the name, respectively, «torrent».
