Logmein hamachi blocked incoming traffic. Setting up the Hamachi program for online games. Why might a blockage occur?

If a blue circle appears next to your gaming partner’s nickname in Hamachi, this does not bode well. This is evidence that it was not possible to create a direct tunnel; therefore, an additional repeater is used for data transmission, and the ping (latency) will leave much to be desired.

What to do in this case? There are a number of simple ways to diagnose and correct it.

In most cases, fixing the problem comes down to a simple check of data transmission blocking. More precisely, the built-in protection of Windows (Firewall, Firewall) very often interferes with the program’s operation. If you have an additional antivirus with a firewall, then add the Hamachi program to the exceptions in the settings or try disabling the firewall completely.

Regarding basic protection Windows, then you need to check your firewall settings. Go to “Control Panel > All Control Panel Items > Windows Firewall” and click on the left “Allow interactions with an application...”

Now find in the list the desired program and make sure that there are checkmarks next to the name, as well as on the right. It’s worth immediately checking the restrictions for some specific games.

Among other things, it is advisable to mark the Hamachi network as “private”, but this may have a negative impact on security. You can do this the first time you start the program.

Checking your IP

There is such a thing as “white” and “gray” IP. To use Hamachi, “white” is strictly necessary. Most providers issue it, however, some save on addresses and make NAT subnets with internal IPs, which do not allow a separate computer to fully access the open Internet. In this case, you should contact your provider and order a “white” IP service. You can also find out the type of your address in details tariff plan or by calling technical support.

Port check

If you use a router to connect to the Internet, there may be a problem with port routing. Make sure that the “UPnP” function is enabled in the router settings, and “Disable UPnP - no” in the Hamachi settings.

How to check for a problem with ports: connect the Internet cable directly to network card PC and connect to the Internet by entering your name and password. If even in this case the tunnel does not become straight, and the hated blue circle does not disappear, then it is better to also contact your provider. Perhaps the ports are closed somewhere on the remote equipment. If everything goes well, you will have to delve into the router settings.

Disabling proxying

In the program, click “System > Options”.

On the “Options” tab, select “advanced settings”.

Here we look for the “Connect to server” subgroup and next to “use a proxy server” set “No”. Now Hamachi will always try to create a direct tunnel without intermediaries.
It is also recommended to disable encryption (this may fix the problem with the yellow triangles, but more on that in a separate article).

So, the problem with the blue circle in Hamachi is quite common, but fixing it in most cases is very simple, unless you have a “gray” IP.

Most often, Hamachi, like other network programs, is hindered by the built-in Windows firewall(called a “firewall”) and an antivirus installed on the computer. Therefore, if during a connection test you see a “blocked” message in Hamachi incoming traffic, check your firewall settings,” which means you need to disable both and try to connect again.

Firewall

It's very rare for a default firewall to block Hamachi, but it's best to check to see if it has anything to do with it. Open the search (I talk about Windows example 10) and enter the word " firewall", then run it.

Go to " Turn Windows Firewall on or off" and disable it for private and public network.

Check the connection in Hamachi, is the error gone? If yes, then the problem is in the firewall, add the program to its exception or disable it while using it.

Antivirus

Most common cause lack of access to the Hamachi network is installed antivirus. Disable it (and the firewall built into it too, if it is disabled separately). Check the connection - it should be restored. If this happens, I recommend not keeping the antivirus disabled, but adding Hamachi to its exceptions. Contact your antivirus manufacturer for instructions on how to do this.

Hamachi is a program that allows you to create your own secure network from various computers on the Internet in such a way as if these computers were connected to each other by a physical network. In addition, using Hamachi you can create a LAN ( local network) on top, that is, separately from the Internet. Of course, this method greatly increases its reliability, and penetration of this network by outsiders becomes almost impossible. In this article we will tell you how to configure Hamachi in such a way that the network is as efficient as possible. We'll talk about how to set up Hamachi on Windows 7 and others operating systems, and we will start with a description of the installation of this program.

Hamachi installation

Everything is simple here. After you have downloaded installation file, run it on your computer (if you don’t trust the source you downloaded from too much, check for viruses first) and click “Next”. Now we need to agree to the terms of use of the program by checking the box in the right place, and click “Next” again. Then we will be asked to indicate the directory (folder) in which the system will install Hamachi - here you can also select options such as downloading the program along with loading Windows and adding a launch icon to the desktop.

Don't forget to check the box next to "Block vulnerable services...". Then we select the non-commercial use of the program “Non-commercial license” and click on the “Install” button. Next, the installer will perform all the necessary operations, after which you can begin setting up the application.

How to set up Hamachi on Windows 7

To do this, look at your desktop. See the icon bar below? We need the right corner of this panel. Find the network icon there (it looks like a computer monitor) and click on it right click mice. In the drop-down menu, select the bottom item (“Network and Sharing Center...”) by left-clicking on it. Now in the menu that appears, select “Advanced” and then “ Additional options».

You will see a list of connections under "Connections". Move the connection labeled “Hamachi” to the very top of the list and configure the bottom menu for that connection under the “Hamachi Bindings” heading accordingly. In this menu, you need to check the box next to the “Internet Protocol Version 4” items and uncheck the “Internet Protocol Version 6” items. For correct operation Hamachi is very important.

Now find the item “Change adapter settings” on the left and click on it. Here you also need to uncheck the “6th protocol” and put it on “4th”. In addition, for protocol version 4, select “Properties” - the button is located just below on the right. In the IP address field, you must enter the address exactly as specified in the main window of the Hamachi program. Now click on the “Advanced” button (it’s at the bottom). You will see the Advanced TCP/IP Settings menu. On the “IP parameters” tab, in the “Interface metrics” item (it’s at the very bottom), set the value to 10. That’s all, now all that’s left is to restart the computer and you can operate the program, so to speak, in full mode.

How to properly configure Hamachi on Windows XP

Here the settings are similar to Windows 7, but somewhat simpler. Open the Start menu (the round button in the lower left corner of the desktop) Control Panel and click on “ Network connections" Next, click on the “Advanced” tab and then “Advanced options”. Just as in the case of Windows 7, you need to put Hamachi at the top of the list, otherwise the program will have no effect. Now all that remains is to restart the computer and see if the settings are saved. If Windows Firewall is blocking Hamachi on your computer, make an exception for the program by selecting Firewall in Control Panel or going to its settings from the blocking message dialog box. That's it: the program will start working.

Hamachi, like other network-based programs, is often noisy. The reasons include Firewall, that is, the firewall built into Windows, as well as the antivirus that is installed on your computer. If, while testing your connection in Hamachi, you get a message that incoming traffic is blocked and you need to check your firewall settings, disable both and then try to establish a new connection.

Firewall Features

It is extremely rare for Hamachi to be blocked by the default firewall. However, just in case, it is better to play it safe and make sure that it is he who is involved in the blocking. First, open a search, for example, in System BIOS Windows 10, type the word “firewall” and run it.

After checking the connection on the Hamachi system, determine whether this error. If it disappears, then the firewall is to blame. The Hamachi program should be added to exceptions or the antivirus should be disabled while starting and working in the program.

Antivirus features

The most common reason why Hamachi does not connect to the network is that the antivirus is blocking it. To prevent this from happening, the antivirus and the Firewall built into it, if it is disabled separately, should be disabled. After this, check the connection. As a result, recovery must occur. If this happens, it is recommended to keep the antivirus disabled all the time or simply add Hamachi to the exceptions. To get more detailed settings For antivirus, you should contact the manufacturer or read the instructions.

Despite the efforts of the Hamachi developers to make this program as “friendly” and simple as possible, many users still have difficulty setting it up. By following the instructions below, you can easily configure Hamachi correctly for gaming or work.

General setup of Hamachi on Windows
In this article we will look at how to configure Hamachi 2.2.0.541 - the most available today. The example demonstrates the setting Hamachi for Windows 7, since this OS is the most common today.

In general, Hamachi does not require any additional configuration; all you need is to install the program, run it, and click on the “power” button (Fig. 1).

After this, you need to connect to the network of interest by clicking “connect to existing network"(Fig. 2) or "network" -> "connect to an existing network" (Fig. 3).

If there are enough free slots in the network, you will connect and see a window with a list of participants (Fig. 5).

In this case, you need to either register for free in the LogMenIn system (Fig. 7), or log in if you already have a LogMenIn account.

If Hamachi does not connect to any network, click “system” -> “parameters” (Fig. 9).

Select the lowest item in the left panel - “Parameters”, find “Encryption” there and set the type to “Any” (Fig. 10).

Then click the item located at the bottom of the window “ Additional settings"(Fig. 11).

If you do not use a proxy server, set the corresponding attribute with the “no” flag (Fig. 12).

Please note that when using a proxy, connection problems may be caused by it.

Then resolve names using the mDNS protocol (Fig. 13).

Disable traffic filtering by selecting the “allow all” flag in the corresponding field (Fig. 14).

Enable presence in virtual network Hamachi (Fig. 15).

Confirm the changes made (Fig. 16).

Close the program and enter it again.

If the above does not help, try temporarily disabling your antivirus.
Also, sometimes Hamachi does not connect due to the Firewall blocking it.
To turn it off, click " Start» -> Control Panel -> Firewall-> Enabling or disabling Firewall
(Fig. 17) (Fig. 18) (Fig. 19) (Fig. 20)

Open two arbitrary free ports in your router settings (each specific model The router has its own specifics for opening ports - see the instructions). Then configure Hamachi to use them by specifying the local TCP address and local UDP address attributes in the already familiar “advanced settings” window (Fig. 21).

After that, restart the router and restart Hamachi. Important point- when “forwarding” ports, do not confuse the addresses for TCP and UDP protocols!

Special cases of Hamachi configuration
It is worth noting that this program is often used by gamers to build gaming networks, as well as various organizations to create corporate file sharing systems. In such cases, you should strictly follow the instructions of the gaming community or your company. However, at the same time, you must understand that if you decide to download and install a third-party unofficial Hamachi distribution, you are endangering the security of your PC - unless absolutely necessary, refrain from connecting to such networks.

How to set the language in Hamachi?
Unfortunately, there is no optional language selection in the program. In order not to run for a dictionary, it is enough that you have the Russian version of Hamachi. If for some reason you need a different language, reinstall the program after downloading the “hamster” localization corresponding to the language you are interested in.

Note that Hamachi official website provides the ability to download only the English version of Hamachi. We can do it.
