When does the need to open the Windows port? Then, when the built-in computer network protection program is a Windows Firewall, also known as Firewall, blocks the operation of a particular application. Often, these prohibitions come across games that require Internet access, or other useful programs. To open the port, follow the following.
1
You can change the firewall settings in the appropriate section "Control Panels", from where you need to go to the "System and Security" section, and then in Windows Firewall. Or press the "Win + R" combination and enter "Firewall.cpl" in the "Run" window that opens, and you will quickly fall on the page. In the latest versions of Windows, you can find the desired program or section of the "Control Panel" section through "Search" in the desktop menu.
2
Only the "Advanced Settings" section, which is in the left part of the settings window. Then, in the Windows Firewall window, find "rules for incoming connections" and click on them. A list of already existing rules will appear, but you have to create a new one. To do this, click "Create Rule" in the "Actions" window (located on the right side of the screen).
3
Now the configuration wizard will help you configure the port, successively offering to set its parameters. In the "Rules Type" window you need to choose the item "for the port" and click "Next". In the "Protocols and Ports" window, define two parameters - the type of protocol and port. If you know a specific port number that you need, specify it in the column "Certain Local Ports". It is also permissible to designate the range, for example, 1244-1250. As for the protocol, TCP usually requires, but sometimes the UDP port is also needed. In this situation, you will need to create two rules alternately. By clicking "Next", you will go to the next setting step.
4
Select "Allow Connection" in the "Action" window, click "Next", and without changing the parameters in the next "Profile" window, press "Next" again.
5
The last action is to come up with a name for the port and if desired, the description, since after a while you can not remember what this port is. And do not forget about the "Finish" button.
6
The port opening procedure is exactly the same for Windows Vista, 7, 8 and 8.1. If you have Windows XP, you can get to the desired settings through the "Start" - "network environment", then you must click "Network Tasks" - "View network connections". By right-clicking on the Internet connection icon, select "Properties" - "Advanced" - "Parameters". Open a new port by clicking "Add", then enter the name or IP address of the port in the appropriate graph. Specify the numbers (any numbers) of the ports in the "External Port" and "Internal Port" fields, then the port type and click "OK".
For security reasons, do not forget to close the ports when there is no longer necessary.
