Ways to open ports on Windows. Ways to open ports on Windows Open port 1723 windows 10

Sometimes a problem arises related to the inability to access any sites. The reason for this may be a closed port. The connection through which data is received and sent on a computer is called a port. The article will help you figure out how to open it using the built-in firewall (firewall) of Windows 7, 8, 10 and a router.

Opening a port using a firewall

The created settings are identical in all modern operating systems, so the procedure will be the same.

First you need to get into the firewall. To do this you need to log in Control Panel, section - System and security. Or press Win + R. In the window you need to write firewall.cpl.

In the window that appears, find the Additional options button:

After that, in the column on the right, click on Rules for incoming connections:

In the column on the left there is an item - create a rule. Click on it:

We need a rule for the port, so check this box and click Next.

A new window will open where you need to specify the type of protocol and ports to which this rule will be applied. It is not uncommon, for example, for games, to create two rules.

After this you need indicate action, which will be executed in accordance with the created rule. Select Allow connections (including connections protected by IPSec and without protection).

After this, your Profile will open. Here you need to make sure that all types of profiles have checkboxes (domain, private and public):

The wizard will then ask you to provide a name and description for this rule. To do this we write any name. You are allowed not to write anything in the description. Click Finish.

Now in the windows firewall we find the created element and check whether the port is open. This can be done using PFPort Checker.

If the port still does not work, you can try to activate it using another method. To do this, we will create a rule again, only it will not be for the port, but for the program:

Next, specify the path to the program using the “Browse” button:

After this, we all do the same as in the first case. Thus, a new rule has been created that should work.

Opening a port on the router

In order to open a port on the router itself, you need to follow the step-by-step instructions:

In the address bar of any browser you need indicateIP-router address. A window will appear in which you need to write your username and password:

Next, click on the Firewall button and select virtual servers:
In the next window let's create a rule to forward the port on the router according to the image:

It is important not to get confused - in the last paragraph “Internal IP” is the address of the computer, not the router. Then we save the changes.

Disabling the firewall Windows 7, 10

If in this case the port does not open, you can try disabling the protection completely. To do this, go into the firewall settings, using the search window (Win + R), select the item Enable and disable Windows firewall.

The Component Configuration dialog box will open:

After pressing the button " OK» computer protection against virus programs from the network will be disabled, which is not recommended. Therefore, you can resort to this only in extreme cases, for example, to check the operation of the firewall itself or when moving from one filtering program to another. Constantly working with the firewall disabled is dangerous and poses a big risk to your computer.

Thus, there are two ways to open a port for a website in Windows operating systems: by changing the settings of the firewall and the router itself. If both do not help, you can try completely disabling the built-in security log.

If you are a system administrator, then you need to know everything about open ports on Windows 10. But you don’t need to remember them, as we provide information on this page.

If you don’t know anything at all about what open ports of Windows 10 are, then it’s better to start this topic with a little theory. At the same time, many have heard of this term, but its meaning is not always clear to everyone. Most users are simply not interested in such information, but if you have an interest in this, then it’s worth continuing. Since there should still be a small theoretical basis.

What are Windows 10 ports

When starting a conversation about such concepts, try to imagine some kind of long tunnel through which two devices interact. And in order to get into it, you need to use something that resembles a door. It is these doors that can be called device ports. Each device has open “doors” through which they can interact with the system. This point should not be confused, since these are completely different interfaces.

The greatest interest among gamers and other users is precisely the “open doors” through which it is possible to interact with the World Wide Web to join some kind of game server or download movies and other content from torrent trackers. Sometimes, to maintain the functionality of such applications, users have to independently unlock the “door”. That is why it is important to learn how to work with such system settings.

How is it possible to check open ports on Windows 10? If you don’t go into the weeds and don’t talk in detail about the system settings, then you can use third-party applications for such tasks. However, this can also be done using the tools that the OS itself can provide you. To do this you need a command line running as administrator:

• Open the system interpreter or the “Run” line;
• Enter "cmd" there;
• After opening the desired tool, enter “netstat -aon | more".

The specified command gives the system an order to display information about:

• A - a list of connections and ports waiting for it;
• O - process ID;
• N - address and door number;
• MORE - display information in page mode.

As a result, you may find yourself with a large list of “doors” and their states:

• Open - Listening;
• Connected -Established;
• Not responding - TimeWait;
• Will close - CloseWait.

Keep in mind that if you don't understand what you're doing, by closing or opening something, or making other changes, you can cause so much harm to the system that it will eventually break and you'll need to reinstall Windows.

It turns out that open ports on Windows 10 are a system option, which is worth working with only if you understand it. In other cases, it is better not to touch this issue as long as it works correctly. Did you like the article? Share with your friends:

• Useful programs for Windows 10

Knowing which Windows 10 ports are open and which are closed is useful to everyone. We will tell you everything, as well as how to open a closed one and close an open one.

Today, some users may encounter a problem when some application, program or toy requires opening a certain port in order to function correctly. Therefore, it is worth talking about which ports are already open in Windows 10 or what you will have to do for this.
Speaking correctly from a technology point of view, a port is usually called a parameter of the entire transport protocol, which ensures correctness of independent data transfer for certain applications, utilities and other software. If we try to express ourselves more clearly, then this parameter can be compared with the house or apartment number in a regular paper letter. If this number is not specified reliably, the letter may not be delivered to the recipient.

Using Windows 10 Firewall to Open a Port

First, let's remember what a firewall is - it is a defender built into your OS, which is designed to prevent programs from accessing the network on their own without your knowledge or remote attackers from gaining access to your PC. Installing this element is not required at all, however, if you have a need for more professional protection than what is built into the OS, you can always use or that have built-in firewalls.

If you decide to use the built-in capabilities, then to do this you should follow these steps:

• We enter the “Control Panel” and then go to the “Firewall”;
• In the section with additional parameters, click “rules for incoming connections” and click “create rule”;
• If we are talking about how to open a new port, then in the next window that opens you need to specify exactly this type of rule;
• Click “Next”;
• Select the TCP/UDP protocol and indicate the specific value of the opening ports. There is no need to open all local positions here;
• Specify an action option for a given value;
• Specify the local network profile;
• Set the name and rule, click the “Finish” button.

It is worth understanding that each game or specific application has its own rules. And in this case, they may need their own open Windows 10 ports, which you should be careful with. It happens that a newly created rule affects the security of the system and viruses can invade it. Incorrect configuration settings also sometimes lead to blocking of a certain application. Even if it is a system one and a separate parameter was allocated for it in the firewall.

Please note that if you open any ports, you should always understand what consequences this will bring. The fact is that every change to the standard security policy leads to your PC becoming more and more vulnerable to external threats.

Computer security experts recommend examining all open Windows 10 ports and, if possible, not making any changes to their settings. If you need to do this for any reason, then be sure to remember everything that you have changed and cancel these changes as soon as there is no longer a need to save them. We also recommend strengthening the protection of your PC - be it a desktop or a laptop, this will help you protect yourself from problems.

• Best programs for Windows 10

Let's start with basic knowledge of what a port is and how to open them on Windows 10 - imagine a tunnel through which there is interaction between two points, 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 can protect the system - like a stone wall is a house, and every new port opening hurts it.

Gamers and fans of downloading huge data packages from the Internet ask on various forums about how to open this or that port, and what its meaning is - we’ll tell you more about this.

Checking ports

Before we start opening ports, let's check which of them are already open, there are special programs for this, but now we will use the built-in Windows tools. Let's get started.

• Run cmd as administrator +[X] → “Command line (admin) →

• Type “cmd” without quotes → OK.

• We also type “netstat –aon | more" → [enter]

In the command, we indicated that we need information about the state of network connections and ports being listened to with the following parameters: a – all connections and waiting ports; o – show process ID; n – show the port number and address in numerical terms; more – page output.

In this simple way, we learned how to look at the ports, we get the answer in tabular form, according to the ports, now about the decryption:

• “LISTENING” - port is listening;
• “ESTABLISHED” - point-to-point connection established;
• “TIME WAIT” - response time exceeded;
• “CLOSE WAIT – connection waiting for closure.

A little later, in more detail, using several examples as an example, we’ll look at how to open a port in a 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's busy with what...

We figured out where you can find ports on Windows 10 and how to figure out whether they are open or in standby mode, now let’s see which program uses open ports, perhaps we don’t need it. Let's remember the screenshot on which the list with PID numbers of the process is text_19/screenshot_03

Let's see who this mysterious guy is under PID 4

• Go to task manager ++ → “Details” → for convenience, click on the “Process ID” column - it will be 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, which includes game engines, updates, etc. If problems begin in the above applications, “NT Kernel & System” begins to hang up the processor.

443 HTTPS

One of the popular ports and is used in secure gaming channels and cloud services, in the address bar, pay attention to the beginning, if there is https:// - HyperText Transfer Protocol Secure, indicates that it works through port 443 - supports encryption, increasing security . To the question of how to open a port on a computer in Windows 10 yourself - it’s quite simple, below are step-by-step instructions.

1. +[R] → enter “firewall.cpl” → OK

2. In the “Windows Firewall” window that opens → “Advanced settings”

3. “Rules for incoming connections” → on the right “Create a rule”

4. “Rule type” → “For port”

5. At this point we show how to open port 443 on Windows 10; when selecting Protocol, select TCP and enter our port.

Pay attention to the block on the right, the newly opened HTTPS -443 has appeared there.

80 HTTP (before this WWW)

What can we say, thanks to this port we are all on the network; 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 in step 6, enter our 80 and also select TCP.

As you can see, with simple manipulations and 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 until step 4.

• “Rule type” → “Program” → “Program path” → “Browse” - select the location of the executable *.exe file.

Each step is shown in detail in the screenshots.

Setting up for torrent

Using the already proven method, we repeat steps up to 6, and indicate the following:

• “Rule type” → “For port” → “Protocol and ports” indicate “TCP protocol” → “Specified local ports: 33033”.

• Before the naming step, everything is identical; we give the name “torrent” accordingly.

I would like to answer the most common question: how to find out your port on Windows 10? There are plenty of ways:

• there are a lot of resources on the Internet that will determine your IP and port;
• +[r] → “cmd” → “ipconfig”;
• “Start” → “Settings” → “Network and Internet” → “Status” → “View network properties” - comprehensive information about your connection is displayed.

On our website you will always find useful information, including:

• how to get help in windows 10.

Ports for games should be opened not only on the computer, but also through the router settings. Modern routers not only allow you to filter modem mac addresses and create virtual servers. Among the firewall settings there are ports. Before torturing yourself and the hardware, it is recommended to do a few simple steps: check how the toy behaves without one or another system component. For example, connect to your ISP directly, without a router, or disable the Windows 10 firewall.

And then you are surprised to see posts where you ask how to forward a particular port, and next to it it says that the error does not disappear if the firewall is completely disabled. The answer is obvious: the reason is something else. Is the provider limiting something, or is it the router’s fault? Or maybe the antivirus is plotting? You first need to localize the cause, then just start working on it.

General procedure

Rarely do providers prohibit their clients from doing anything, so it is recommended to start by studying the following components of the system:

1. Antivirus (Windows Defender does not count).
2. Firewall.
3. Router.

Each of these subsystems has methods for prohibiting and allowing access to certain input/output ports of network information. There are quite a lot of them, and many are prohibited. This is necessary to protect against hackers who are always looking for which port to contact in order to overturn the system. Before starting setup, try disabling all these components in sequence. If the problem persists, it is useless to try to configure an antivirus, firewall, or router.

Windows Firewall

• Right-click on the monitor icon in the lower right corner. Sometimes he hides in the tray, so you have to get him.
• Go to the Network and Sharing Center.
  
• In the lower left corner, click the desired link and select Advanced options from the left column of the window that appears.
  
• The new snap-in allows you to set rules for incoming and outgoing connections. Here you can choose to open any port completely, or only for the desired program. If you don't know the name of the module, then choose the first option. Otherwise, open the port for the desired application and only for it.
  
• Let's say that we go to set up an outgoing connection. Select the appropriate option in the left column and click Create Rule on the right.
  
• Let's say we want our Notepad to communicate with someone over the network through any ports. Select the desired option in the wizard and click Next.
  
• Select the path leading to the file.
  
• Allow the program to communicate.
  
• All you have to do is click Next a couple of times, set a title (name) for the rule, and you’re done.

What if you only need to set one port? Then:

How to forward a port in a router

The name is entered arbitrarily, for example, by the name of the game. The protocol is most often UDP. The internal IP address can be viewed via the Status link in the LAN clients section.

This completes the router setup.

Port forwarding in antivirus

Antivirus instructions vary greatly. You need to contact the manufacturer every time. To be fair, we note that forwarding software is usually not difficult. There is a section of so-called exceptions, where you need to add the module of the program you are using. It's worse when the application consists of several parts. Note that in the top ten, antivirus no longer plays as big a role as it did before. Trojans do not crawl through all the cracks, unless you download dubious software from obscure sites.

Final verdict

The most detailed information is usually posted on the game forum. Some of it is in English, so you need to learn the language. There is no other option here. Technical information is most fully presented on the foreign Internet. Ultimately, if all else fails, call your provider. Some of them could play it safe and close all unnecessary ports. So no game will be able to get through the firewall, and it is useless to try to open ports on Windows 10.
