Surely many have heard that in someIn some cases, it is required to open ports so that, for example, a resource becomes available on the Internet. True, not everyone knows how to open ports in Windows 7 - one of the most popular "OSes" of today. Let's look at the aspect of general solutions to this issue, and also look at some of the nuances.
Why do we need ports?
We will not delve into the jungle of system processes,and try to figure out how to open ports on Windows 7. First of all, everyone should know that ports, in fact, in the broadest sense, are some kind of universal communication channels through which you can connect to certain resources on the same Internet. This is sometimes a prerequisite for being able to participate in an online game or access a private server.
In addition, some specific ports are used by various devices in the system itself. Let's stop on this separately.
How to open ports on Windows 7: general solution
So, initially this whole procedure comes down tochange firewall settings. We immediately say: this general solution can only be used in cases where the connection is made directly through the cable, and not a Wi-Fi router type router (in this case, the ports will need to be configured on the device itself).
How to open ports on Windows 7? Easy peasy.To start, go to the Control Panel, where we select the system and security section. After that, select the firewall setting. In this section, we are interested in additional parameters, after the selection of which, the Advanced Security mode settings window opens.
Here at the left above we use the line of rules forincoming connections, and then create a new one (the port is selected as the component). In the next step, we specify the TCP protocol, the port number, and then allow the connection. Further, the profile settings that appear can be left unchanged. Then we enter the name of the new rule and click the "Finish" button.
Issues of opening and changing com-ports
As for how to open com-portsWindows 7, there is nothing particularly complicated here either. Sometimes this procedure will be needed in order to reassign the reserved ports for some devices, or simply remove unused ones.
First, click on the computer icon on the Worker.table and select the property bar. On the tab, click on the environment variable button, after which you will need to create a new variable named DEVMGR_SHOW_NONPRESENT_DEVICES with a value of 1 (this will display all the ports and devices using them in the corresponding manager).
Now we call Device Manager either fromControl panels, or the devmgmt.msc command, enter “Run” in the menu bar. It is necessary to sort the list of devices by type. In the COM- and LPT-ports section, all unused devices will be visible, which needlessly occupy the corresponding ports. They can be completely simply removed. Port mapping is performed in the submenu of the properties of any component installed in the system.
How to open ports on Windows 7 for Minecraft
Что же касается открытия портов для одной из The most popular online games called Minecraft, here you can apply two basic methods: set them up manually or use special utilities, which is much easier. Let's start with the second.
You can install a small utility calledSimple Port Forwarding, after starting the program, you need to specify the port number 25565, your IP address and set some additional parameters. But here it should be noted that the application is shareware, and a week after the start of its use will have to buy.
So the user will need to know howopen ports on Windows 7 for this game manually. Let us examine the situation on the example of routers. First, through the browser, you need to enter its settings and refer to the Port Forwarding section. Here you will have to create a new connection, and in the settings list enter the IP of the router itself, the IP of the provider server, the number of the required port (25565) and do not forget to tick the box next to enabling TCP. After that, you need to save the settings and just restart the router and computer (laptop). As you can see, this technique is somewhat more complicated, since you have to contact the provider (at least, in order to find out the address of its server).
Conclusion
If you sum up some small result, you canIt should be noted that there is nothing particularly difficult in opening the ports in the G-7, just like in any other system. Here you just need to pay attention to the type of port being opened, since the specificity of the procedure being performed will depend on this. It goes without saying that you should take into account the type of Internet connection, because the general methodology works only in cases of direct connection of a computer or laptop via a fiber-optic cable. For a Wi-Fi connection, setting up a router is similar to connecting to Minecraft servers. In the extreme case, all the necessary data can be obtained from the provider, if some parameters are not automatically configured. Finally, nothing can happen if some ports are simply not supported by the provider or are blocked for some reason.
