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.
Concerning 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 interaction with the 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 note Hamachi network, as “private”, but this may have a security impact. 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.
Hamachi is latest program to create a secure network over the Internet that performs the function of a local one. As a result, it turns out that computers located at a great distance are tied to each other according to the principle local network over the Internet. But even modern programs have glitches, one of which is “Tunnel through a repeater”. The main disadvantage of this problem is the low speed of the game and endless crashes from servers as a result of weak ping. In this article, we will tell you how to fix a tunnel through a repeater in Hamachi.
Why does this problem happen?
The problem of a tunnel through a repeater is quite common and completely solvable. The cause of the problem is that the program cannot reach the computer directly, and therefore seeks communication through third-party servers. In this situation, the indicator next to the name of one of the network members lights up blue.
Fixing a tunnel through a repeater
To remove a tunnel through a repeater, follow exactly the instructions below. By completing all the steps, you will create favorable conditions for creating a direct tunnel between computers.
1. First you need to check if your IP is white. The fact is that for a direct connection between computers, at least one of the users must have a white IP. You can get a white IP through the provider that provides you with the Internet.
2. When Hamachi is running, the antivirus and firewall must be disabled. You can disable the firewall through the Control Panel, System and Security - Windows Firewall. You can disable the antivirus until the next reboot, or for some time, for example, 30 minutes.
3. Go to Hamachi and open the Options panel. Open in settings " Additional settings" and change the "Use proxy server" value to "No".
4. Restart Hamachi and check the LED color of the user you want to connect to. If it is green, then you have been able to fix the tunnel through the repeater.
Now you know how to fix a tunnel through a repeater in Hamachi. If you still can't fix it this problem, then you need to check the settings of your router or provider to prohibit the use of direct ports. Also ask another user to follow the same steps above. We hope you will be able to set up Hamachi and play seamlessly with your friends online on highest speed and low ping.
Always popular. In cases where it is not possible to lay the wire (for example, your partner is in another city), a program such as Hamachi will come in handy. She creates a game that allows you to enjoy playing cooperative campaigns.
True, people who decide to use this method may face an unpleasant problem - a tunnel through a repeater. This means that for some reason direct access to another computer is impossible, and communication goes through the program’s servers. This seriously reduces the quality of communication and often makes it impossible to play online.
The problem is common, but, fortunately, in most cases it can be solved. A typical sign that the connection is not direct and a tunnel has been created through a repeater is a blue indicator next to the name of a network member. Ideally, the indicator should be green. In new versions of the program, it is now possible to ping contacts in the network list. If the ping fails, messages will appear indicating that the request has timed out - this is a clear sign of a problem.
First of all, check the antivirus software on both computers; the firewalls built into them need constant monitoring, otherwise they have a habit of blocking Hamachi. The repeater is deactivated as soon as you receive a stable connection with your network partner. Try disabling the protection; if the connection is still unstable, proceed to setting up the program.
In find "Network Properties" and disable "Encryption". Also, run the program only as an administrator (like the game). Then, with a high degree of probability, the program will not create a tunnel through the repeater. In general, Hamachi is a rather capricious program, so sometimes it creates a tunnel even when communication can be established directly. This usually happens when one of the network participants has a slow connection.
Among other things, it’s worth checking if you understand this, or calling specialists: it all depends only on the degree of your awareness. It is pointless to give advice in this case, because... There can be any number of reasons “on the other side”. Without understanding the principles of operation and configuration, you can easily break something, and then the problems will become more serious.
At the same time, a tunnel through a repeater is not always bad, because Some games have enough quality that the Hamachi server provides. If the connection suits you, then why change anything? If the problem cannot be resolved in any way, neither by your efforts nor by the efforts of the provider, then, as an option, change the company that provides you with Internet services. Of course, this will cause you some inconvenience at first, but a high-quality connection is worth it.
A tunnel through a repeater is an extremely annoying problem that should be fixed as soon as possible. Another thing is that the price of the issue can vary from 15 minutes of your time to a radical change of provider. Be prepared for this. Remember, it’s better to sit without the Internet for a couple of days, but then forget about connection problems forever.
Hamachi is a program that specializes in building private virtual networks (VPNs). The utility provides the ability to create a personal secure network from personal computers(PC) and laptops connected via the Internet. At the same time, it is possible to emulate a physical local network.
You can download it from the official website - www.vpn.net.
Tunnel problems in Hamachi are one of the most common problems with this application. Errors of this type promise unpleasant consequences for users, due to which it is impossible to contact other participants in the virtual local network - the ping may increase, up to the loss of packets with the message “Timeout interval exceeded.” Moreover, this problem may arise due to various factors: incorrect settings, conflicts with security programs, etc.
How to remove the yellow triangle
Configuring network parameters
Before looking for the “VPN Status” error in the Hamachi program (similar to the “VPN domain tap device is disabled” error), you need to do some preliminary PC setup:
Using these manipulations, the user is likely to remove the yellow triangle from exclamation point in Hamachi. If the problem does not go away and the yellow triangle still appears, this indicates that the problem is most likely located on the side of other users connected network. If the yellow triangle error occurs for all participants, then a number of additional actions will have to be taken.
Changing Hamachi settings
The problem with the tunnel in Hamachi can be resolved by changing the settings:
note! Additionally, these settings will help fix the peer connection problem.
Other solutions
To get more detailed information Regarding the yellow triangle, you can right-click on the problematic connection and select the option “ Intelligence». 
In the " Summary» users will be able to find detailed information about the connection type, encryption method used, etc. If there is a reason found within Hamachi, the conflicting parameter will be marked with a yellow triangle and the text will be written in red.
For example, if problems are detected in a private virtual network " VPN status", then users need to check that the Internet connection is working correctly, and that the Hamachi utility is configured correctly.
Sometimes it will help to remove the yellow triangle error in Hamachi restarting the system and program. If the problem is not solved either in the Hamachi program or in the panel Windows management, then you should pay attention to your antivirus or firewall. As a solution, try adding the utility to exceptions or temporarily disabling system protection
Blue circle in Hamachi
Now let's consider another situation, when the tunnel through the repeater begins to work incorrectly.
Checking network blocking
The lion's share of problems associated with blocking networks comes down to banal internal OS protection. Very often, Hamachi is interfered with by standard Windows protection. Try adding Hamachi to exceptions, as well as disabling other security tools when running the utility.
To disable Windows system protection, you need to go to " Control Panel" and go to " Windows Firewall" Open your firewall and allow operating system interact with the Hamachi application. 
Checking the IP address
There are such concepts as “white” and “gray” IP addresses. To use the Hamachi program for the user required "white"IP address. Most providers immediately issue a “white address” to clients, but there are also companies that save on the address. In return NAT subnet is provided using internal (gray) IP. It does not allow a single PC to fully access the World Wide Web. In such situations, you have to change your tariff plan or order a white address connection from your provider. Information about the type of IP address You can find out by reading the tariff plan agreement or by calling the provider’s technical support service.
Port check
If you use to connect to the Internet Wi-Fi router, then you need to look for the error in port routing. The user needs to check what is in the router options function"UPnP" enabled. In turn, in Hamachi it is worth prohibiting the disabling of “UPnP”.
Proxy settings
To disable proxying, go to the Hamachi program. In the utility, find the tab “ System» – « Options" In the parameters column, select "". In the window that opens, in the attribute " use a proxy server» Select the “no” option. 
Hamachi does not start, but self-diagnosis appears
The problem with self-diagnosis is that instead of the normal launch of the utility, Hamachi starts a continuous self-diagnosis. Despite the prevalence of this error, the problem can be solved in three simple steps:
Hamachi was unable to connect to the network adapter
If Hamachi is unable to connect to network adapter, then most likely the problem lies in connection settings. To fix the problem you need:
Odnoklassniki - the most popular social network, which in terms of the number of registered users is second only to VKontakte in the Russian-language segment. Like any other social network, Odnoklassniki has a lot of nuances that you need to know. In our case, we will talk about a user activity indicator.
There are three ways to identify friends on Odnoklassniki: study the state of his avatar, track dates and times latest entries in the Feed or write a private message. The interlocutor may respond immediately or not respond to the message while online - but how to find out?
Avatar state
You can determine whether a friend is online by paying attention to his main photo. Log in to Odnoklassniki by entering your username and password. In the window that opens, click the “Friends” tab.
The list that opens contains users whose acquaintance has been confirmed by a mutual request to be added to the list of friends. The lower left corner may flash blue or orange circle.
Its blinking means that this friend is currently on the site. The same symbols appear if you click on the Guests tab.
The color of the icon will tell you what device your friend is using to log into the social network. If the circle is blue, it means the user is using a phone, smartphone or tablet. If Odnoklassniki is opened from a computer or laptop, the orange icon blinks. If you go to the friends tab and select “Friends Now Online” in the left menu, all online friends will have orange or blue dots flashing. People’s avatars have the same designations in the “People are currently on the site” section in the left menu of their personal profile.
IN telephone version the orange icon remains round, and the indication that a friend is logged in from a phone or tablet resembles the shape of the phone in the left corner of the photo.
User is offline
Clients of the social network notice that after leaving the site, they remain online for 5-10 minutes and continue to receive messages. Why does the circle blink if a friend has left his page? If you close the Odnoklassniki page on your computer along with the browser or tab, your friend remains visible online for another 5 minutes. During this time, the system records the lack of activity, execution of actions, and determines that you are offline. If the account is open, but no new entries are made in the Feed and no actions are taken for five minutes, the dot under the photo will disappear. To instantly log off the network and not appear in your online friends’ lists, you must first click on the “Logout” button on the top panel:
Or select the drop-down Client Menu next to the avatar thumbnail and click “Exit”. The system will instantly log you offline and you will not appear in online lists.
Ability to hide online
Invisibility will not help hide your presence on your personal page - icons are shown for every friend who accesses ok.ru from any device and performs actions in the account: viewing the feed, profiles, groups, listening to music. Invisibility is designed to be hidden in the Guests section. If you visit someone else's account, its owner will instantly receive a notification about the guests and will be able to explore your Feed in response. Invisibility allows you to hide visits to other accounts - when you log into them, notifications will not be sent.
