Every year, electronic communications are improving, and ever higher demands are placed on information exchange for the speed, security and quality of data processing.
And here we will take a closer look at a vpn connection: what it is, what a vpn tunnel is for, and how to use a vpn connection.
This material is a kind of introductory word to a series of articles where we will tell you how to create a vpn on various operating systems.
vpn connection what is it?
So, a virtual private network vpn is a technology that provides a secure (closed from external access) connection of a logical network over a private or public one in the presence of high-speed Internet.
Such a network connection of computers (geographically distant from each other at a considerable distance) uses a point-to-point connection (in other words, "computer-to-computer").
Scientifically, this connection method is called a vpn tunnel (or tunnel protocol). You can connect to such a tunnel if you have a computer with any operating system that has an integrated VPN client that can “forward” virtual ports using the TCP / IP protocol to another network.
What is vpn for?
The main advantage of vpn is that negotiators need a connectivity platform that not only scales quickly, but also (primarily) provides data confidentiality, data integrity, and authentication.
The diagram clearly shows the use of vpn networks.
Beforehand, the rules for connections over a secure channel must be written on the server and router.
how vpn works
When a vpn connection occurs, information about the IP address of the VPN server and the remote route is transmitted in the message header.
Encapsulated data passing over a public or public network cannot be intercepted because all information is encrypted.
The VPN encryption stage is implemented on the sender's side, and the recipient's data is decrypted by the message header (if there is a common encryption key).
After the message is correctly decrypted, a vpn connection is established between the two networks, which also allows you to work in a public network (for example, exchange data with a client 93.88.190.5).
As for information security, the Internet is an extremely insecure network, and a VPN network with OpenVPN, L2TP / IPSec, PPTP, PPPoE protocols is a completely secure and secure way to transfer data.
What is a vpn channel for?
vpn tunneling is used:
Inside the corporate network;
To unite remote offices, as well as small branches;
To serve digital telephony with a wide range of telecommunication services;
To access external IT resources;
To build and implement videoconferencing.
Why do you need a vpn?
vpn connection is required for:
Anonymous work on the Internet;
Application downloads, in the case when the ip address is located in another regional zone of the country;
Safe work in a corporate environment using communications;
Simplicity and convenience of connection setup;
Providing high speed connection without breaks;
Creation of a secure channel without hacker attacks.
How to use vpn?
Examples of how vpn works are endless. So, on any computer in the corporate network, when establishing a secure vpn connection, you can use mail to check messages, publish materials from anywhere in the country, or download files from torrent networks.
Vpn: what is it in the phone?
Access via vpn on your phone (iPhone or any other Android device) allows you to remain anonymous when using the Internet in public places, as well as prevent traffic interception and device hacking.
A VPN client installed on any OS allows you to bypass many settings and rules of the provider (if he has set any restrictions).
Which vpn to choose for the phone?
Android mobile phones and smartphones can use applications from the Google Play market:
- - vpnRoot, droidVPN,
- - tor browser for surfing networks, aka orbot
- - InBrowser, orfox (firefox+tor),
- - SuperVPN Free VPN Client
- - Open VPN Connect
- - Tunnel Bear VPN
- - Hideman VPN
Most of these programs serve for the convenience of "hot" system configuration, placement of launch shortcuts, anonymous Internet surfing, and selection of the type of connection encryption.
But the main tasks of using a VPN on your phone are checking corporate email, creating video conferences with multiple participants, and holding meetings outside the organization (for example, when an employee is on a business trip).
What is vpn on iphone?
Consider which vpn to choose and how to connect it to an iPhone in more detail.
Depending on the type of network supported, when you first start the VPN configuration on iphone, you can select the following protocols: L2TP, PPTP, and Cisco IPSec (in addition, you can “make” a vpn connection using third-party applications).
All of these protocols support encryption keys, user identification with a password and certification.
Among the additional features when setting up a VPN profile on an iPhone, one can note: RSA security, encryption level, and authorization rules for connecting to the server.
For the iphone phone from the appstore store, you should choose:
- - free application Tunnelbear, with which you can connect to VPN servers of any country.
- - OpenVPN connect is one of the best VPN clients. Here, to run the application, you must first import rsa-keys via itunes to your phone.
- - Cloak is a shareware application, because for some time the product can be "used" for free, but to use the program after the demo period expires, you will have to buy it.
Creating a VPN: choosing and configuring equipment
For corporate communication in large organizations or the consolidation of offices remote from each other, they use hardware equipment that can support uninterrupted, secure networking.
To implement vpn technologies, the following can act as a network gateway: Unix servers, Windows servers, a network router and a network gateway on which VPN is raised.
The server or device used to create a vpn network of an enterprise or a vpn channel between remote offices must perform complex technical tasks and provide a full range of services to users both on workstations and on mobile devices.
Any router or vpn router must provide reliable network operation without “freezes”. And the built-in vpn function allows you to change the network configuration for working at home, in an organization or a remote office.
vpn setup on router
In the general case, VPN configuration on the router is carried out using the router's web interface. On "classic" devices for organizing vpn, you need to go to the "settings" or "network settings" section, where you select the VPN section, specify the protocol type, enter your subnet address settings, masks and specify the range of ip addresses for users.
In addition, to secure the connection, you will need to specify encoding algorithms, authentication methods, generate negotiation keys, and specify DNS WINS servers. In the "Gateway" parameters, you need to specify the ip-address of the gateway (your ip) and fill in the data on all network adapters.
If there are several routers in the network, it is necessary to fill in the vpn routing table for all devices in the VPN tunnel.
Here is a list of hardware equipment used in building VPN networks:
Dlink routers: DIR-320, DIR-620, DSR-1000 with new firmware or D-Link DI808HV router.
Routers Cisco PIX 501, Cisco 871-SEC-K9
Linksys Rv082 Router Supporting About 50 VPN Tunnels
Netgear router DG834G and router models FVS318G, FVS318N, FVS336G, SRX5308
Mikrotik router with OpenVPN function. Example RouterBoard RB/2011L-IN Mikrotik
Vpn equipment RVPN S-Terra or VPN Gate
ASUS RT-N66U, RT-N16 and RT N-10 Routers
ZyXel routers ZyWALL 5, ZyWALL P1, ZyWALL USG
Apple makes it easy to set up a VPN for an iOS client that supports L2TP, PPTP, and IPSec. If your company has a private intranet that you need to access on the go, or if you're traveling the world and want your iPhone to think it's still in your country (or another country), a VPN will help you.
A virtual private network or VPN is a service that creates a direct connection from your computer/phone to another network. Some businesses have an internal intranet that can only be accessed while at work. The VPN can create a secure connection by redirecting the connection to this location.
It is often used when logging into public Wi-Fi. It will redirect you to a different endpoint so you won't see who is using the public network.
It is also regularly used to bypass site blocking. This is useful if you want to access content that is prohibited in your country.
Before you start
You can use a VPN service such as , or . All you need to get started with one of these services is to download the app on your iPhone or iPad.
You can also set up your VPN client manually.
Before you begin, you will need information such as the server address, username, and password. If you don't have this information, contact your system administrator or your company's technical support, or contact your VPN service for assistance.

Connecting and disconnecting VPN for iOS
Once you've set up your VPN, you can open the Settings window and toggle the VPN slider at the top of the screen to connect to or disconnect from the VPN. When you connect to a VPN, the "VPN" icon will appear at the top of the screen in a row.
If you've set up multiple VPNs on your iPhone or iPad, you can switch between them by going to Settings > General > VPN - the same screen where you added this VPN.
Connecting to OpenVPN
Although Apple hasn't added OpenVPN support for iOS directly. Like Android, iOS supports third-party apps to implement and operate VPNs. This means that you can connect absolutely any type of VPN from your iPhone or iPad, as long as the app has a third party app that can connect to it.
In the case of OpenVPN, there is an official app that you can install. Install the app, run it and use it to connect to OpenVPN VPN.
To set up a VPN server in the OpenVPN Connect app, you will have to import a profile - this is a .ovpn file. If you want to do it manually, you can connect your iPhone or iPad to your computer, open iTunes and select the connected device. In the Applications section, you will be able to copy the .ovpn file and its associated certificate and key files to the OpenVPN application. you can connect to the VPN from the app.
The OpenVPN Connect app and similar apps are not "just an app" that you use. They provide a system-level VPN connection, so all apps on your device will connect through the VPN, just like the VPN connections you connect to in the normal way from the built-in settings app.
This is for the home user. Large organizations centrally managing iPhone or iPad deployments will want to avoid configuring each device and specify a VPN server via configuration profiles or a mobile device management server. Provide a configuration profile file with all VPN settings specified in it, and users can download and install this configuration profile to instantly get the appropriate VPN settings configured on their devices.
Where to start
First of all, you need to have a place on some computer. The easiest way to do this is on any hosting by renting a virtual server. I searched and tried different servers, but it was most convenient to do it on . Such a server costs $5 per month, and this will already be enough for the full operation of the VPN.
Moreover, there is a certain feature here that allows you not to pay a fixed monthly fee, but to use the server only when necessary, for example, turn on VPN in certain countries, airports and other unsecured Wi-Fi networks.
After reviewing a number of instructions on YouTube, I found the perfect recipe. In order not to write a lot of unnecessary letters, just watch this video, which clearly shows how to set up such a VPN in 10 minutes.

What you need on iPhone
Step 1. So, it is assumed that you have already set up your VPN on Digital Ocean and received the configuration file. Now, in any way, we throw it into the iPhone, for example, through DropBox. I would venture to suggest that since you have figured out the server settings, you do not need to tell how to upload a file to the iPhone.
Step 2. We go to the App Store and download OpenVPN Connect there - the application is free.
Step 3. Just click on the config file uploaded to DropBox in the first step, for example, it can be called client-smart.ovpn
click "Export" - "Open in" - "Copy to OpenVPN"
Step 4. Almost done! Now it remains to click on the green plus sign to apply the config in the application.
Step 5. And click "Connect" to connect iPhone to the server.
Ready! Now you can use VPN to its fullest without any problems.
What you need on MAC
If you watched the video carefully, you probably realized that you can create an unlimited number of configs for different devices. You can create a separate config for a MAC or Windows computer as well.
After that, on the MAC, you need to download the Tunnelblick application, link to (for free) and also add the resulting config there, after which you can connect to it and use a similar VPN.
What are the advantages of such a VPN?
1. High transmission speed. When returning 50-80 Mbps from the router, VPN gives out 20-60 Mbps.
2. Both iPhone and MAC have the same IP address, which allows all services to work correctly.
3. There is no need to pay every month, but you can pay for the server by the day and even by the hour.
Now, when in many regions of Russia one or another popular Internet service can be turned off at any time, VPN is gaining particular popularity. However, not all users know what it is and how to encrypt their connection on an iPhone or iPad. But sometimes it is simply necessary.
First, let's understand what is meant by a VPN. This is a technology for protecting your Internet connection, which works on a fairly simple principle: your device receives a request to connect to a VPN server, and only then you get on the Web, due to which all traffic goes through the VPN. Roughly speaking, this is a kind of intermediary between you and the World Wide Web, which, in addition, provides an IP address, masking the user's real location.
There are quite a few ways to install a VPN on an iPhone or iPad, but today we will look at one of the simplest and most common - installing a special application from a VPN service.
One of these programs may already be familiar to some of our readers - TunnelBear. Install it for free on your iOS device using the link below, register and get 500 MB per month for your travels on the Web. For posting on Twitter, the service will give you a bonus one gigabyte.
After downloading the application, you will be prompted to install the TunnelBear profile, and after that you can use the utility to your heart's content. Just choose the country you want to use the server for and connect to it. For an additional fee, you can expand the number of gigabytes available for surfing the Internet.

If you are often on public Wi-Fi networks, using a VPN becomes a real must. Therefore, these utilities will be useful to any user of iOS gadgets who spends a significant amount of time on the Web.
The Betternet app provides VPN services. The service is activated on the iPhone with one click and connects to the optimal location. If you need to connect to a specific location, you can choose from several countries, including several locations in the US for a small monthly fee. It is safe, fast and stable.

There are many legitimate reasons to use a VPN. A VPN (virtual private network) service hides your IP address by redirecting your internet connection point to a different IP address in a different location. This allows you to visit websites while hiding your location.
You don't need to use a VPN all the time, but it's ideal when accessing the internet through an unsecured public Wi-Fi hotspot or visiting sites that are restricted based on your location. Quality iPhone VPN apps don't store your browsing history or personal information. The best free VPN app for iPhone is Betternet.
SettingVPN connections viaBetternet
The VPN protocol is an integral part of the iOS core, so the Betternet app only provides a hotspot. After downloading the app, you need to set a configuration profile in Settings so that iOS knows you want to connect to the VPN protocol through the Betternet app.
You can then return to the Betternet app to get started. The easiest way to connect is to click on the Connect button. Within seconds, the Betternet app will connect your device and you can start using the internet. The service is free and secure.
The Betternet app does not analyze your data. On their site, the developers explain how they make money, none of which involve illegally using your data or showing annoying ads.
The only way to monetize is through ads on the Betternet app, not while visiting web pages. From time to time, when connected to VPN networks, the application will ask you to view a short advertisement. The button will say “Watch video and connect”, but after a few seconds your VPN connection will be activated. You can decline this request: click on "Skip and connect" under the main button.
Feel free to reject offers entirely. The next time you connect to VPN networks, open the Settings app and turn on the VPN option at the top of the tab. As long as you have the Betternet app installed and the added profile is present, your device will connect to VPN networks without ads or the need to run third-party apps. If you want to support Betternet, launch the app and watch a short advertisement.
Extendedfunctions andlocation change
A quick activation of Betternet is more than enough for most users who want to use a VPN service. For those who are trying to access blocked sites in an office or country, more functionality is needed.
The premium version of the app offers users multiple location options, faster connections, and priority technical support. The cost of use is $4.99 per month or $29.99 for annual service - the latter option benefits from a 50 percent discount.
Location options in the premium version include seven cities in the United States: Atlanta, Chicago, New York, Virginia, Los Angeles, Salt Lake City, and Seattle (Virginia is a state). Alternatively, you can connect via an IP address from the United Kingdom, Canada, the Netherlands, France, Australia, Germany, Singapore, or Hong Kong. This gives you precise control over your IP address in an already intuitive VPN app interface.
Betternet charges money for the ability to change location, but the cost is low, especially if you buy an annual subscription to the service. Another disadvantage of the service is the lack of information about the currently used IP address or location, even if you connect for free. The app tells you that you're connected "from the best location" in the United States, but doesn't specify from where.
