The mobile office today has ceased to seem like a phantom and technology of the transcendent future. Smartphone users have the ability to launch applications and work “on the go” - when traveling abroad, on vacation, and even outside the workplace during office hours. But is it so easy to configure the operation of applications on a smartphone so that they "catch" a corporate network protected by harsh system administrators? Even an inexperienced user can do this using a VPN server.

VPN (virtual private network) is network technology providing access to resources corporate network outside of its perimeter, for example, from home or from another office. It allows you to secure data transmission over the network, since when using it, public communication channels are not involved: that is, the device connected to the VPN channel is virtually inside this network, but physically it can be anywhere where there is the Internet. Typically, such access is given to employees who often work from home or from branch offices, but with the development of smartphones and mobile applications This technology has also become in demand among mobile workers who do not part with their phones on vacation, at lunch, or in a train or car on the way to an important meeting. How do you provide them with access to the organization's network?

In addition to regular VPNs, there are VPN servers that are adapted for the use of mobile devices. The difference between them is that such devices often change the communication channels used - this can be a 3G / 4G network, and then Wi-Fi, which greatly complicates the work of a traditional VPN server (it sees connections from different IP addresses and subnets, but cannot save a dedicated communication channel for them). As a result, applications from the smartphone periodically lose their active connection and do not work. To prevent this from happening, VPN servers use additional authorization systems, for example, IPsec, which allow organizing data exchange for mobile devices that often change their network settings, but at the same time located within the same operator's network, or SSL for more flexible authorization in the web interface.

For a long time, only smartphones based on Symbian OS and Blackberry and Windows Mobile communicators were adapted to use a mobile VPN connection, but with the appearance of the iPhone and Android on the market and the gradual displacement of the leaders, VPN can be "raised" on Google and iPhone. ... Let's see what needs to be done for this using the example of the HideME.ru VPN service.

To connect mobile VPN access on a smartphone, you need to enter the settings network connection- they are in the section Wireless network- VPN. In HideME.ru, you need to select the type of device for connecting to the VPN - from mobile devices there are ready-made wizards for connecting via PPTP / L2TP in Android and iOS, as well as for other devices by analogy. The service issues a list of VPN servers through which traffic is tunneled (that is, data transfer to and from the Network), provides a general security key IPsec networks and on this the setting can be considered complete. VPNs can be switched to non-L2TP mode specifically to ensure compatibility. What does HideME.ru VPN service give?

Firstly, this provider provides 2048-bit encryption of all traffic both at the application and network levels (that is, even an open Wi-Fi connection becomes secure). Secondly, resources that have regional restrictions(for example, watching videos on Youtube, the author of which prohibits their viewing in Russia, or online radio, which does not work in Europe, but is available to users in the United States). Thirdly, VPN allows you to bypass P2P traffic restrictions imposed by operators. cellular for fans of torrents and Skype calls (in order to avoid network congestion and withdrawal of subscribers from their own services voice communication). Fourth, a VPN through a foreign Internet provider can work faster than a "native" one, which will be appreciated by those who like to send large amounts of data.

Naturally, we control the whole process of working with VPN - the user can change his IP-addresses and open / close ports, making his Internet sessions anonymous and safe. HideME.ru has several tariff plans, which can be distributed from 1 day of work with VPN, and up to 2 years (taking into account the discount for long-term use), and the cost of the service is about 1 ruble per day when purchased for a year or more. You can also test the service absolutely free for one day.

Modern smartphones delight users with more and more new functions, and with each next model, previously unknown possibilities are added. Today, smartphone owners do not use all the functions of their devices, because many are simply unknown to them. We continue to understand the useful capabilities of modern phones and we are next in line... We will find out what it is for, in what situations to use it and how to enable it in smartphones with different OS.

What is Virtual Private Network

If you translate the decoding of the abbreviation literally, you get the following - a virtual private network. That is, it is a certain technology through which a logical network with one or more connections is created. In this case, a secure connection is created on top or inside the existing network (a kind of tunnel), through which, using special application, the network user accesses a dedicated VPN server. Inside the connection, the maximum protection of the transmitted data is ensured by means of special encryption and modification.

Recently, such services, allowing conditionally anonymous use of the Internet, are becoming more and more popular, and therefore smartphones have also provided similar opportunities.

Let's figure out in what situations it is advisable to use a secure connection through a VPN. This feature is perfect for people who often use open WiFi hotspots, for example, at the airport and other public places. An unsecured WiFi connection can lead to theft of the owner's confidential data, please agree modern smartphones in this matter, just a tidbit for scammers. In order to avoid the possibility of data interception, send important information over unsecured channels, it is worth using a VPN.

This is not the only utility that comes with the use of a virtual private network. Its use allows you to open a resource that is blocked in a specific region or, in general, in a country. It is also a great way to get around corporate network restrictions.

VPN what is it in the phone

Now we know what it isVPN, what is it on the phone,Next, let's figure out what is the difference between these technologies from desktop ones. A VPN connection can also be used on a computer by accessing the Internet from a full-fledged browser. However, the very technology of forming a tunnel and providing a continuous connection differs, primarily due to the peculiarities of the connection to the network itself.

When accessing the Internet from a computer, a stable channel is used without possible interruptions that lead to the burst of the tunnel and disclosure of data. Communication channels when using mobile gadgets are constantly changing. Depending on the type of network available, the smartphone shows either 4G or LTE, then 3G. Because of this, an ordinary server is not able to maintain continuous communication with a mobile gadget. In this regard, many cloud technologies VPNs have been adapted to these features and provide customers with the ability to use the network without fear of losing security.

A mobile connection often uses a dynamic IP that changes regularly, and therefore a regular VPN server interrupts the current connection and activates a new session. To avoid such phenomena, the adapted services use a special type of authorization that allows you to correctly identify the client, even if the IP address changes frequently. In this case, it becomes possible to transfer data two-way from the VPN server to smartphones that change network settings. This approach allows you to organize more flexible interface authorization.

How to use this feature on a smartphone

We have already figured out VPN what is it in the phoneand realized the benefits of using this feature. Now it's time to figure out how to connect and use a virtual network.

For starters, it should be noted that there are both paid and free VPN servers. Which one to use is up to the client, but to ensure the maximum degree of security, it is not worth saving. Besides, paid services open up more possibilities. After the choice in favor of one or another server is made, you should go to the connection settings directly in the smartphone.

Setting up in iPhone

"Apple" smartphones give the user the opportunity to independently set up a VPN or use ready-made solutions from App Store... In the second case, you just need to select a ready-made application in the Market and install it, turn on VPN in the settings and select the installed service.

For manual setting the algorithm is a little more complicated. But if you follow our recommendations, there will be no difficulties.

Then you can use the internet. In order to make sure that you get the desired result, you can pre-test the Internet connection for special service, which are enough on the net.

Setting up on smartphones with Android OS

It is worth noting that the owners of these gadgets are more fortunate. VPN setup is much easier on their smartphones.

No other settings are required. As you can see, it is much easier to set up and use a virtual network in Android than in an iPhone.

Now the question VPN what is it in the phoneyou will not have. We have analyzed the technology in detail, figured out the directions of its use and the features of servers intended for mobile clients. In addition, we learned how to set up and enable VPN on different smartphones... We are waiting for everyone who has questions in the discussions, we will try to answer them. If the article turned out to be useful, share it in in social networks.
