Lots of people don’t know yak nalashtuvati vpn connexion, the prote on the right is not cunning, but it shows singing skills. To get started, let's figure out what we need. VPN is literally translated as a virtual private network. As the name suggests, it serves to create a tunnel between two computers, through which information is transmitted in encrypted form.

Setting up VPN Windows completed, now to connect you just need to click on the shortcut on the desktop or on the icon in the connections “Start” menu.

There is much more to setting up a private virtual network than just registration and activation. Our guide will help you get the most out of this privacy and security approach.

Kozhen is guilty of using a virtual private network (VPN) regardless of the method of connecting to the Internet: be it a computer or a smartphone. It is possible, without sounding paranoid, that if true threats actually arise, the stink will become even worse. Attackers may try to steal your personal information through Wi-Fi networks. Every time you go online, your Internet Service Provider (ISP) has access to everything you control, and Congress has given the go-ahead for advertisers to sell your anonymous information. In the vast expanses of the Internet, advertisers and scammers can find your benefits across sites and your promotion site by looking at your IP address. It doesn't sound like a croak.

The truth is that the Internet is not broken up in order to protect your privacy. These are designed to facilitate the exchange of information, and not for the purpose of providing anonymity, confidentiality or encrypted storage. Although HTTPS connection does a lot to protect your information, it does not protect against attacks on Internet providers or on local networks, which in its own right is a serious problem, since you have never been exposed to your for example, in hotels or cafes.
And while the new, more confidential Internet does not show up (you may not show up at all), using a VPN is the easiest way to ensure that you share special information on your desktop, lyki is possible. Make no mistake: you need virtual privacy.

What a VPN can and cannot do

As with other security tools, it is important to understand the capabilities of a VPN. I'm sorry, you won't suspect that the bulletproof vest will protect you when you fall from a flying plane, or that the parachute will hit your butt.
When you turn on a VPN, your traffic goes directly through an encrypted tunnel to the server secured by the VPN company. This means that neither your Internet provider, nor anyone (or anyone else) connecting to your router will pump your Internet traffic. Your traffic enters the Internet through a VPN server. If you go to a site that does not use Vykorist's HTTPS connection, your traffic will no longer be encrypted.

And since your traffic exits the VPN server, your reference IP address is safely received. This is important because IP addresses are distributed geographically and can be used to determine your location. If you want to find out your IP address, you can find out the IP addresses of the VPN server. And this may be beneficial if you want to change your place of growth. By connecting to a VPN server in London, you can make it appear as if you are accessing the Internet from the UK.
Here's what VPNs can't do: keep your traffic completely anonymous. For this purpose, it is better for you to use services such as Tor. This miraculous anonymization feature can be easily accessed through a special version of the Firefox browser. Instead of transferring your data through one intermediary (via a VPN server), Tor redirects your information through a number of different computers within the Tor network. This makes the process of accelerating your activity and your daily routine much more complex.

In addition, websites may track your browsing behavior through cookies, collection of specific information in the browser, online trackers and other unintended applications. A vicious ad blocker like Privacy Badger can help stifle these viewer predators and also make it more difficult for advertisers to stop you from moving around.
And let’s face it, the fact that you have a private virtual network does not mean that you can forget about the basic rules of security. Regardless of those VPN services that claim that they can block viruses, we recommend an anti-virus software for your computer, since it has been developed to protect your computer from harmful programs.

It is also better for you to use a password manager, because repeated abuse of the same password is often the main cause of malware or infection. Another guard lies in the existence of primary intuition when opening messages or supplements in electronic sheets. Phishing attacks are attacks where the attacker creates a fictitious site that is copied from the site in order to fool and tempt you into entering your personal data - the tables are wider, which have become practical everyday life, so be careful.

Yak Vibrati VPN

When choosing a VPN, there are a number of key points that will help you gain respect. For example, a VPN service is liable to allow you to connect to five devices at the same time, at a minimum. We also respect that the VPN service allows the vikorrent service to intercept BitTorrent traffic on its servers. Some people allow it, but some people don’t, so it’s out of respect, even if you don’t want to be disappointed in the company, so you pay a fee.

Speaking of payment, the average VPN cost is $10.53 per month. Just because a VPN service charges a monthly fee more than the price, this does not mean that they are robbing you, but that they are guilty of paying you in return. For example, a shorter interface or a large number of servers to expand in order to improve the service a little. Make sure you receive a discount when you sign a long-term contract, otherwise we do not want you to work until you are completely happy with this service.

Persh nizh kupuvati VPN, read the mind and service carefully. This document will show you what information the VPN service stores and what you can do with that information. Lots of companies insist that they don’t keep traffic logs, which is wonderful. Others go further and insist that the stench does not follow the activity of the koristuvach in the future. This is important because a VPN has access to all information that you want to protect from others. In the brightest minds of the service, all the overhauled moments are clear-sighted, but in the darkest ones, everything is foggy, with a great deal of emphasis on details and on the law. If you feel like you are deciphering Petkin’s letter, when you read one of these documents, be warned that you will need to go to another service. TunnelBear, for example, clearly and succinctly explains its services in an easy and accessible way.

Also, we won’t wonder if there is a VPN company. Remember that it is not just the physical aspect of growing a company, but the legal aspect, which indicates under what jurisdiction the company operates. For example, NordVPN is located in Panama, and ProtonVPN is located in Switzerland. This means that this company is not subject to data privacy laws, so security services can deny access to information that is still stored on them. Another example, Hide My Ass VPN, is found in the UK, where similar laws are more harsh.
The most important thing when choosing a VPN is trust. So if the place is out of price, the price or the service quality does not inspire confidence in you, then try another service.

Best VPN services in 2020:

Paid or cost-free VPN

We recently conducted a survey of 1000 people on the topic of VPN VPN. According to our results, 62.9% of respondents say that they should not pay more than $5, and 42.1% say that they want to use a cost-free VPN.
Unfortunately, most VPN services are far from providing their services free of charge. Or I would like less than 5 $. But you don’t need to rob a bank in order to be stolen. After a trial subscription to the service for 1-2 months, you can sign up for a long-term contract, thereby changing your expenses. Private Internet Access VPN is a wonderful and affordable service that costs only $6.65 per month for the services you expect (without extra charges).

Most VPN services offer a trial period, which is based on hourly subscriptions. Others, such as TunnelBear and AnchorFree Hotspot Shield Elite, offer completely cost-free versions of their products, but with certain restrictions, as they do not rely on paid clients. For example, TunnelBear keeps track of the data of its catless clients. And the cost-free Hotspot Shield version runs on advertising. ProtonVPN - the creators of the stolen email service ProtonMail - also has a trial period.
The Opera browser may require a cost-free VPN and will not charge you anything for its use. Opera also offers premium VPN add-ons for IOS and Android absolutely cost-free, providing you with protection no matter where you go.

Let's get started

As soon as you install the service, first, you are obliged to earn it in order to attract an additional contribution to the company. Call for special attractive pages on the VPN service website. So go ahead, download the add-on onto your mobile devices; The more devices you destroy, the better it is for you. With most options, you pay once for a subscription to a number of licenses (call it five), and then you can use the service on any device, for which there is a special add-on.
We have discovered that when VPN is released for Mac, the versions of add-ons in the Mac App Store may differ from the versions available on the VPN service website. Judging by this, it is also being traced through the Apple company. Through a series of tests and compromises, you can, of course, find out which version you will use, and we have worked for you in our reviews.

After you have installed the add-on, you will be prompted to enter the input information. Most entries will have the same password as you provided during registration. Companies, such as Private Internet Access, assign you client usernames in addition to your payment information to ensure greater client confidentiality.
After you leave, your VPN add-on connects to the VPN server closest to you. In order to ensure good speed through the VPN, blockages and changes in speed will increase in the world between your work and the progress of the VPN server. Axis and everything: now your information is sent through a secure tunnel to the VPN server.

Please be aware that you are not obligated to install the VPN company add-on. Instead, you can adjust the network parameters of your device in order to immediately connect to the VPN service. If you are concerned about possible restrictions “under the hood”, then this option is best for you. Most VPN services have instructions for setting up your device.

select server

Otherwise, you may not want to connect to the server that the VPN add-on recommends. You may want to expand your networking experience by accessing BitTorrent via a VPN or, most importantly, quickly using the customized servers that your VPN company provides you with.
Many VPN companies include an interactive map in their add-ons. For example, in NordVPN you can click on the edge to connect to their servers. This is an accessible way to understand where your information is going, and there will be a list of servers from which you can choose.

The choice of server will depend entirely on what you want to earn. For security and speed, it is better for you to choose a server close to you. To access region-specific content, you need to select a server in a specific region. For example, if you want to watch the BBC, you'd better connect to a tunnel in the UK. Some VPN companies, KeepSolid VPN Unlimited and NordVPN, for example, have special servers for streaming video.

These special servers are important because streaming services like Netflix block VPNs. We are talking about licensed content that is stolen by studios and Netflix itself. For example, Netflix has the rights to broadcast Star Trek: Discovery outside the US, but if you're in the US you'll need to pay for CBS's All Access service.
It would also be a good idea to check whether your VPN service allows BitTorrent traffic on all servers or only on special ones. NordVPN, like many other services, makes it clear that it does not allow vicarious torrents. Ale TorGuard, for example, has nothing against it and allows you to play torrents on all servers of the company.

Services such as NordVPN and ProtonVPN offer advanced security options, such as access to the Tor network or multi-hop VPN. As stated earlier, Tor is a tool for ensuring a higher level of privacy. It allows you to deny access to websites on the so-called Dark Web. A multi-hop VPN works in a similar way: instead of redirecting your traffic through one VPN server, a multi-hop connection transfers you first to one server, and then to another. Offensive propositions work for the benefit of confidentiality, but not for the sake of privacy.
If you choose to ignore third-party add-ons and configure the settings manually, then you may have to enter information for the skin VPN server separately.

expansion of adjustment

The selection of functions in a private virtual environment varies from service to service, so we can only specify and admit that you can download before you open the settings panel. We also recommend that you read the documentation and try clicking the buttons. The best way to learn how to vikorist is to try it, vreshti-resht.
Most VPN services include the Kill-Switch function. Once enabled, this option prevents the computer from accessing or transmitting information via the Internet until the VPN is turned off. This function is useful if your computer is connected to a VPN and you can transfer (or receive) bits of information over an unencrypted connection.

Many services offer the option to select a VPN protocol. It seems that the protocols have strange, obscure names, and companies rarely provide information about those who will change the protocol. Zagalom, here and there, you can deprive yourself of peace.
If it still bothers you, then OpenVPN is the protocol we recommend. Vіn is in public access, so that he looked at a lot of eyes on the possible sensitivity. IKEv2 is a good, safe replacement since OpenVPN is not available. Please be aware that on all platforms, such as macOS and iPhone, OpenVPN is always available through additional interfaces and overlays for retailers.

Koli varto koristuvatisya VPN

To ensure the highest level of security, you must use private virtual networks as often as possible, and ideally at all times. Ideally, it is something that can be reached at any time. At a minimum, you should choose a VPN if you use a network, do not control it, and especially if it is a public Wi-Fi network. We most often recommend that users adjust their VPN add-ons so that they work better. You can switch in again, as it is more useful for you to bring insecurity.

VPN for Android and other mobile devices is a little more foldable, hidden, if you often enter and leave the access zone to the drone-free range. Every time you connect and re-connect, the VPN will also reconnect, adding to the long-lasting experience. It is also clear that your mobile traffic may be overloaded, but we have been investigating to determine what is possible. Looking at the fact that law enforcement and intelligence agencies have virtually uninterrupted access to telecommunications data, the axis of evil is glad to you: use the VPN at the hour of victorious connection. In addition, most mobile devices can connect automatically to known Wi-Fi networks. At a minimum, you must use a VPN while connected via Wi-Fi, since it’s easy to simply expand your Wi-Fi network.

Many VPN services allow you to configure settings for how and under what circumstances they will be able to reconnect when the connection is disconnected. We honestly can't think of a reason why you wouldn't want your VPN service to try to reconnect, and we recommend that everyone reconnect with the settings set correctly.
If you are being turbocharged because your VPN is sabotaging your connection or blocking important traffic, then you need to look at the split-tunneling option. And again, different companies give different options, but the point is that you are allowed to configure the add-ons that will be used by VPN connections for your traffic, and add-ons, which will operate as normal. For example, TunnelBear includes an option to NOT tunnel Apple apps so they can function on a Mac. Streamers and gamers who require a VPN should definitely check out this option.

How to use VPN for streaming via Chromecast or AirPlay

Chromecast and AirPlay allow you to stream music and video from your computer or mobile device to speakers, TVs and other streaming devices. But all of them require Wi-Fi, which can be problematic if you use a VPN.
When VPN is turned on, your traffic moves through an encrypted tunnel, which prevents devices connected to the same Wi-Fi network from being detected. This is the way it should be, as long as you don’t want to, but just be in the zone of your activity, finding out what you’re doing. Of course, this also means that Chromecast and AirPlay will not work while you are using a VPN.

The simplest solution is to turn on the VPN, otherwise there is no other way. You can use split tunneling, as outlined earlier, to route only the traffic you want to intercept through the VPN. You can also enable the VPN-browser plugin, which encrypts only browser traffic and nothing else.
Alternatively, you can install a VPN on your router. As a result, all devices connected to your router (from your phone to a smart juicer) will be subject to traffic encryption. This is a great solution for well-equipped smart budins.

Private virtual networks are not nuclear physics

At first glance, VPNs can offer some mystical security features, but many companies work diligently on this to make them smart and friendly to the internet. Most of them now do not show any inconsistency. That's how it goes. And if you want to be generous with your protection from possible threats, VPN is one of the shortest and easiest ways to protect your edge traffic from... That's all.

• When choosing a connection protocol, think about how you will choose a VPN. It appears that the PPTP protocol works quickly over a drone-free network, or less securely than L2TP and IPSec. If you want security, check out L2TP or IPSec. When you connect to a VPN on your robot, your robot vendor will tell you which protocol to choose. If you use a high-power VPN, choose a protocol that is supported by your Internet provider.
• When choosing a VPN provider, think about security. If you want to use a VPN to send documents and emails, or want to ensure that your work stays safe, choose a VPN provider that offers SSL (TLS) or IPsec encryption. The SSL encryption protocol is the most popular. Encryption is a method of capturing data from third parties. In addition, choose a VPN provider that uses OpenVPN for encryption, not PPTP. Over the past few years, a number of bugs have been discovered in PPTP; Therefore, OpenVPN is more important due to its more secure encryption method.
• When choosing a VPN provider, think about privacy. Some providers monitor the activity of their clients and can inform the owner if they are suspicious. If you want to keep your online activity confidential, choose a VPN provider that does not keep logs of users.
• When choosing a VPN provider, think about the VPN bandwidth. This indicates how much data can be transmitted. Please be aware that high-quality videos and music files are larger in size and therefore require higher throughput, lower text files and images. If you choose to use a VPN only for viewing and transferring confidential documents, be sure your VPN provider provides sufficient bandwidth. If you, for example, want to watch Netflix or play online games, choose a VPN provider that allows you to access unlimited bandwidth.
• When choosing a VPN provider, think about whether you want to view content that is only available in other countries. When you look at web pages, they show your IP address, which indicates your destination. If you try to deny access to content in another country, you may not be able to do so due to the IP address, since there is no copyright for that content between countries. Therefore, look for a provider with exit servers - in which case you will have the IP addresses of the country you need. This way you deny access to content in other countries, vikoryst and overseas servers. Choose a VPN provider that has servers in the region with the content you need.
• When choosing a VPN provider, think about how you will connect to the VPN on your computer or mobile device. If you are going to get a lot more expensive or frequently use a mobile device (smartphone or tablet), choose a VPN provider that provides VPN connections for mobile devices or provides add-ons that work with your mobile devices yami.
• When choosing a VPN provider, think about what support you need. Read the guide and find out information about customer support by this or another VPN provider. Some providers only provide support over the phone, while others can also be contacted via live chat or email. Find a provider that offers a convenient way for you to support clients. Also search for search results (through a search engine, such as Yandex or Google) about the provider to evaluate the strength of customer support.
• When choosing a VPN provider, think about how much you are willing to spend. Some VPN providers offer cost-free services (for example, Open VPN), but, as a rule, in this type of service (functions, bandwidth, support, etc.) will be reduced. Since there are no one VPN providers, equalize the prices and services of them. You will soon find a provider who will provide you with the services you need at a reasonable price.

Many companies use VPN networks to transfer data between computers. To set up VPN Windows 7, XP, 8 and 10 May, there is a built-in security program that allows you to easily create a private virtual network and use it to protect private information.

Adjustment via Control Panel

On Windows XP, Vista and later versions of the OS, you can create and connect to a VPN network using the installed software. Let's look at these connections step by step:

1. Right now you need to go to “ Control center for barriers and backdoor access" Vikorist search for the program or go through the border icon. You can also use the associated Win + R key and enter control / name Microsoft.NetworkAndSharingCenter in the row

3. Click on the third point "".
   
4. Now you will be prompted to select a method to connect to the server. If in the future you plan to create a VPN connection for Windows 7 from a remote location, for example, at home or a cafe, then you will need to create a secure connection to pass through the Internet. If your computer only works at work in a local network, then select another item without the Internet. To connect, you will need to connect all devices via LAN cables (fiber optic or telephone). It’s better to create a private protected network (VPN) on Windows 7 and other operating systems with connections via the Internet, but it’s easier and more practical for the local government.
   
5. Now Windows XP, 7, etc. Requires data from the user to connect to the server. For this you need to find out the IP or domain of your service provider's server. Enter Їх in the first row. I will name another column for this connection, you can select whatever value.
   
6. The remaining action requires you to enter data to access the event. The customer's name and password are also visible to the postal manager.
   
7. The data entered will then be connected. At this stage, a number of problems and errors may arise due to incorrect operation or adjustments of Windows. Their corrections will be described later.

Once the VPN server accepts the correct data, it will take several minutes for the computer to connect to the new private network. In the future, you will not need to set up connections every time, as you will be able to select a connection quickly.

Additional authorities connection

To ensure that the connection works correctly, it is recommended to change the parameters a little. To do this, after pressing the Connection button in the menu, select the Power button. You can also open this power through the “” section of the Control Panel.

4. In the section " Merezha»Only check the other box (TCP / IPv4). You can also use IPv6.

Setting up a VPN on Windows xp, 7, 8, 10 through the Control Panel is however subject to the following algorithm. The only problem is that the design may change slightly depending on the version of the operating system.

After the installation is complete, you need to go back to uninstall the VPN. For this it is enough to go to the section " Change adapter settings» From the control panel. Next, use the right mouse button to point to an unnecessary element and select “ vidality».

5. Windows XP supported the forward connection function via a telephone number. Here you need to check the box for front connection.
   
6. In the next step you need to enter the VPN server address and the date of your connection.
   

Now the connection can be made through the connection menu. You will also need to enter your account and password to log in.

Creation of a VPN server

These instructions are valid for versions of XP and higher. Unfortunately, through the standard program for creating virtual private networks, you can connect only one client in a session.

8. You need to redirect all connections from port one thousand seven hundred and twenty-three to the creation of a VPN server, you also need to set a stable IP or create a domain name through no-cost services (DynDNS, Free DNS, etc.).

If you do not create a permanent IP or domain name, you will have to change the server address to connect to your account.

Once the creation of the server is completed, you can now connect one client to the next one. To log in, you need to login and password from the previously created account.

VPN server on Windows XP

These instructions are relevant for setting up Windows 7, 8 and 10. In XP, the setup master is used to configure the vikoryst.

1. After selecting the item to create a new input connection, the adjustment master will appear before the user. You need to select the remaining item " Establish a direct connection to another computer“I continued to follow the instructions of the master.
   
2. In the "" window, you must select Allowed connection to the server.
   
3. At the stage of selecting a device for input connections, you can skip selecting a device that uses a modem or LPT (parallel port).
   
4. At the next window, select “ Allow virtual private connections (VPN)».
   
5. Next we move on to the adjustment of the koristuvachs.
   

Once the system is configured, the IPv4 protocol is activated, as on other versions of Windows.

Improved connection via Windows 8 and 10

Connecting to a VPN on Windows 8 has become much easier with Vikoristan and can be done through a small program. Vaughn is distributed in the section " Merezha» - « connection» - « VPN».

VPN connections on Windows 10 and 8 can be established not only through “ Control panel", And th through the introduced program. She needs to enter the name of the connection, server address and login information.

After entering the data, the network can be launched from the Connect menu. On what basis, how to create a VPN connection, you can use the following information.

How to create a VPN server, tricks

If the user has some problems connecting to the VPN, a window will appear with the number and description of the problem.

809

It occurs most often when connected via a MikkroTik gateway with the L2TP protocol.

To correct this, you need to complete 3 configuration steps:

If after these adjustments the 809 error is not known, then you need to change the registry. To do this, use the key combination Win + R and enter regedit Then go to the section HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Rasman\Parameters. Next, create the DWORD parameter with the name ProhibitIpSec and the values ​​1.

After this, restart your PC.

806

After setting up VPN Windows 8 you can appear pardon 806. This occurs when the harness is incorrectly adjusted or the cable is connected incorrectly.

Let's look at the solutions to these problems:

1. Go to setup and change adapter parameters.
2. Next, create a new login connection and in the new one add a user with Internet connections.
3. For connection authorities, you need to select protocol version 4.
4. Now you need to go to the advanced settings for the TCP / IPv4 protocol and uncheck the " Primary mode gateway at a remote boundary».
5. Now you need to allow the firewall to allow incoming connections through TCP port 1723 to allow the GRE protocol.
6. You also need to install a permanent IP on the server and set up data transmission to port +1723.

In this way, it appears that the server will transmit all data through this port and the connection will not be disconnected.

619

On Windows 7, it crashes if the VPN connection security settings are incorrect.

Most problems occur when the user name and password are entered incorrectly, and they can also appear when the connection is blocked by a firewall or when the access point is incorrect. If all entered data is correct, then the payment is due to incorrect security settings. You need to drop them:

1. If you have a VPN connection, go to the security tab and check the recommended settings.
2. It is also necessary to acknowledge the point “ It is necessary to encrypt the data (or else log out)" After this, you need to save your changes and turn off the computer to restart.

A VPN connection allows you to reliably protect all data transfers. Due to advanced encryption protocols, unauthorized persons will not be able to view the information that is transferred between accounts and servers. The main thing is to properly set up the connection to the server.

This article provides a detailed look at the process of setting up a VPN server in the Windows Server operating system, as well as the following: What is a VPN and how to set up a VPN connection?

What is a VPN connection?

VPN (Virtual Private Network) is a virtual private network that is used to secure a secure connection to the network. Technology that allows you to combine any number of devices into a private space. As a rule, via the Internet.

Although this technology is not new, it has become relevant over the past few years through the efforts of the public to preserve the integrity of data and privacy in real time.

This connection method is called a VPN tunnel. You can connect to VPN from any computer, from any operating system that supports VPN connection. Or install a VPN-Client, which is a great way to disable ports with TCP/IP connections in a virtual network.

Why bother with a VPN?

VPN will ensure remote connection to private networks

This way you can safely connect a few networks and servers

Computers with IP addresses from 192.168.0.10 to 192.168.0.125 are connected through a edge gateway, which plays the role of a VPN server. First, the rules for connecting via the VPN channel must be written on the server and router.

VPN allows you to safely surf the Internet when connected to open Wi-Fi networks in hidden areas (in shopping centers, hotels or airports)

And also bypass the restrictions on displaying content in foreign countries

VPN avoids cyber threats by allowing the attacker to dump information into a location that is undetectable to the user.

VPN principle

Let's take a look at how a VPN connection basically works.

It is clear that the transfer of a package along a road route from point A to point B, along the route of the package, checkpoints for the passage of the data package are tightened. If you use a VPN, this route is additionally stolen by the encryption and authentication system of the user in order to secure the traffic in which the data packet is located. This method is called “tunneling”

In which channel all communications are securely protected, and all intermediate data transmission nodes are encrypted in an encrypted package and only when transmitting information to the recipient, the data in the package is decrypted and becomes available to authorized users vacha.

VPN ensures the privacy of your information along with a comprehensive antivirus.

The VPN supports certificates such as OpenVPN, L2TP, IPSec, PPTP, PPOE and is highly secure and secure for data transfer.

VPN tunneling gets stuck:

1. In the middle of the corporate border.
2. Connection of remote offices, as well as other branches.
3. Access to external it resources.
4. For instant video conferences.

Creation of VPN selection and configuration of equipment.

For corporate communication in large organizations or the connection of remote one type of one office, the equipment is equipped to support uninterrupted operation and security at a minimum.

To use a VPN service, the gateway role can be played by: Linux / Windows servers, a router and a network gateway on which VPN is installed.

The router is responsible for ensuring reliable operation of the network without freezing. The added VPN function allows you to change the configuration for working at home, in an organization or in a branch office.

Setting up the VPN server.

If you want to install and use a VPN server based on the Windows family, you must understand that Windows XP/7/8/10 client machines do not support this function, you need a virtualization system, or Desk server on Windows 2000/2003/2008 / 2012/2016, then we will look at this function on Windows Server 2008 R2.

1. To begin with, you need to install the server role “Access Policy Services” For which open the server manager and click on the “Add role” message:

Select the role “Access and Access Policy Services” and press on:

Select "Routing and Remote Access Services" and click Next and Install.

2. After installing the role, you need to configure it. Go to the server manager, open the “Roles” tab, select the “Access Policy and Access Policy Services” role, open it, right-click on “Routing and remote access” and select “Adjust and enable routing” "Remote access"

After starting the service, it is important that the role configuration is completed. Now you need to give your clients access to the server and set up an IP address for clients.

Ports supported by VPN. After the service starts, the stench emerges from the firewalls.

For PPTP: 1723 (TCP);

For L2TP: 1701 (TCP)

For SSTP: 443 (TCP).

The L2TP / IpSec protocol is more suitable for VPN monitoring, mainly for security and higher availability, due to the fact that one UDP session is used for data channels and traffic management. Today we will look at setting up an L2TP / IpSec VPN server on the Windows Server 2008 r2 platform.

You can try the fire on protocols: PPTP, PPOE, SSTP, L2TP / L2TP / IpSec

let's go to Server Manager: Roles - Routing and remote access, Click on this role with the right mouse button and select “ power », On the “Remote” tab, check the IPv4 router, select “local networks and access”, and remote access IPv4 server:

Now we need to enter the front key. Go to the tab Safety and in the field Allow special IPSec policies for L2TP connections, check the box and enter your key. (With the key drive. You can enter there a sufficient combination of letters and numbers, the main principle is that the more complex the combination is, the safer it is, and remember, or we will need to write down this combination). In the “Service Verification Service Provider” tab, select “Windows - Verification Service”.

Now we need to adjust Security connect. For this let's go to the tab Safety and select Methods for verifying authenticity, Check the boxes EAP protocol and Encrypted verification (Microsoft, version 2, MS-CHAP v2):

Next let's go to the tab IPv4, There you can select which interface will accept VPN connections, and also configure the pool of addresses provided to L2TP VPN clients on the IPv4 tab (Set the interface to “Allow RAS to select an adapter”):

Now let's move on to the information that appears in the tab spoil, Press the right mouse button and power, Viberemo connection L2TP and pressed nalashtuvati, Will be displayed in the new window Remote access connections (except external ones)і Possible connections (weekends and weekends) and the number of ports is set to the maximum, the number of ports may be matched or the number of clients transferred may be exceeded. It’s easier to enable non-vikoristan protocols by checking off the offending checkboxes in their authorities.

List of ports that have lost their assigned quantity.

This completes the server setup. It is no longer possible for customers to connect to the server. go to server manager Active Directory – koristuvachi - we know koristuvacha yakoma want allow access under pressure power, Let's go to the bookmark entrance calls
