How can I make a port open in Windows?

Today, we'll figure out how to check if the port is open or not, and also describe how to activate it in a Windows environment. Most of the servers and computer programs are used to access the global network, they interact with each other. These operations are possible due to the activation of ports. They allow access and organize the connection.

Firewall

You need to know exactly whether the port is open, because if it is temporarily unavailable, the invitations in the path are lost and do not arrive. To activate, you need to perform a number of steps, which will be discussed later. Today we will describe in detail how to open ports on Windows. First of all, open the "Control Panel". We change the variant of viewing the content to "Small Icons". Let's move on to the Windows Firewall function. In the left part of the window there are several items, among them we find and apply "Additional parameters". Go to the next dialog box.

Connection Rules Wizard

To check if the port is open, use the function associated with increased security. In the new window, select "Incoming connection rules". Next, we turn to the development of the algorithm. This will help the special "Master", whose goal is to create connection rules. This tool will tell you how to proceed further. At the same time, he will receive a number of important questions. The answers are also provided in advance. Carefully read the prompts on the pop-up windows and, if necessary, click the "Continue" button.

Inbound connection

If the port is not open, we have to go through all the stages of the wizard. First of all, we are offered to choose the type of rule being created. We put a tick in front of the item "For the port", press the "Next" button. Select "Incoming connection". Proceed to the next stage. Next, to open the port, select its number or range. In this way, you can provide unimpeded access to various servers. Before us, a line appears, in which we are talking about certain local ports.

Resolution

If the port is already open, however, you need to do the same with others, separate them with dashes and click the "Next" button. At the next stage, we will offer all kinds of connection options. We pass to the next stage and tick the "Allow connection" checkbox. Thus, the presented connections will become available for the PC. Press the "Next" button. The created rule is applied to the domain, private and public profile, so they are noted during the opening of the port. When all actions are completed, click the "Finish" button. The wizard will quit. We, in turn, will be able to establish connections or receive messages via a new accessible port.

Router

This device allows you to connect several devices to the Internet without much difficulty, and its configuration also directly relates to our current topic. This device acts as a router, provides access to network resources, and also allows you to open ports. First of all, we need to open the router itself. Start the browser and go to the router. Next, we will have a line in which we enter the internal IP. Most often it looks like this: 192.168.1.1. In case of an error, enter 192.168.0.1.

The next step is authorization in the system. For this purpose we fill the following window with the necessary data. It's about the login and password that are provided by the provider. Most often in both fields, specify the word admin. If this data does not fit, look under the router. Below we find all the necessary information. We will see a window with a special navigation bar. Go to the Advanced Setup section. After that, we find and use the NAT function. Then click on the Add button (in the Russian version of the interface, the path is "Settings" and "Add"). In the next window we will find a number of special fields: username, PC address, external and internal port. The combination that must be made in the first paragraph, we have to come up with yourself. In doing so, it should be as memorable as possible. You can also select a name using the provided list. In the address bar, enter the internal IP. In the fields of the external port, specify the following digits 25565. As a result, the internal port will be specified automatically. Then click the "Save" button and open the port through the firewall of the operating system. Any computer connected to the network has 65535 ports. It's about the kind of "doors" that open up access to data. Thus, the interaction of several devices is possible. However, a port must be open for this, otherwise access to the contents of the PC will be limited. Speaking of routers: thanks to them, data packets that come from the network are distributed through a local network between devices. A wireless connection can be established not only between the PC, but even with cameras and household appliances.
