Configure VPN for android

Here I will try to talk about setting up a VPN on Android devices.
Many users have never heard of VPN, and when they saw this item in the settings of the phone, they simply shrugged their shoulders and went on. If you know what a VPN is, how it works, then most likely this article will not tell you anything new, I wrote it for newbies who want to protect their network security, circumvent censorship and regional restrictions, preserve their anonymity.
So what is a VPN?
VPN - (eng. Virtual Private Network) is a generic name for technologies that allow you to provide one or several network connections (logical network) on top of another network (for example, the Internet).
PPTP VPN - PPTP (English Point-to-point tunneling protocol) is a point-to-point tunnel protocol that allows a computer to establish a secure connection to the server by creating a special tunnel in a standard, unprotected network. PPTP places (encapsulates) PPP frames into IP packets for transmission over a global IP network, such as the Internet. PPTP can also be used to establish a tunnel between two local networks. PPTP uses an additional TCP connection to maintain the tunnel. PPTP traffic can be encrypted using MPPE. Various mechanisms can be used to authenticate clients, the most secure of which is MSCHAP-v2 and EAP-TLS.
My task in this article is not a detailed story about a VPN (what it is, how it works, where it came from) you can get the information here: ru.wikipedia.org/wiki/VPN
Go directly to the phone settings, I did everything on my Samsung Galaxy GT N-7100 Galaxy Note2, MIUI firmware, android 4.1.1 settings on other devices are similar. First of all, we need to choose a provider who will provide us with the VPN Service, for myself I chose russianproxy.ru selected the “Download” tariff that is suitable for me, after paying you will send your personal settings to your personal account and e-mail (login, password, name) server) they look like this:

Click on the newly created VPN connection and enter the following information:

If the connection is successful, a key icon will appear in the upper status bar, when you click on it, the following options are available: view connection statistics (time, traffic)

I also want to talk about several programs for working with VPN, which I found in the market.
VpnRoot - play.google.com/store/apps/details?id=com.did.vpnroot conditionally free VPN client, to unlock all functions, donat is required via PayPal, unlike a regular VPN in android, can reconnect after disconnecting, has a widget With the help of which you can activate a VPN session in one click on the desktop until it has autorun, the author promised to add it in the next versions.
DroidVPN - play.google.com/store/apps/details?id=com.aed.droidvpn for work requires registration on the program 's website, after creating a personal account for a month, give 100mb of VPN traffic, then you have to pay, pennies in general something about 150 rubles in three months, I don’t understand users who left negative comments to the program ... There are several VPN servers in different countries to choose from, I liked Italian for some reason, you can make the servers change randomly each time, your ip will correspond to the country whose server you have chosen settings that n It allows one to easily circumvent regional restrictions. The program has autorun, it can reconnect when the connection is broken.
Orbot: Tor for Android - play.google.com/store/apps/details?id=org.torproject.android Tor is an open source, cross-platform software designed to protect against "listening" and ensuring the confidentiality of personal and business data transmitted over the global network. The product provides complete anonymity of clients when visiting websites, publishing materials, sending messages and working with applications using the TCP protocol. Android users have already been given the opportunity to use Tor proxies for anonymous surfing. Some time ago, a group of researchers from the University of Cambridge released a product called Shadow. The new application Orbot is the official version of the Tor-client from the creators of the platform. Tor on wikipedia ru.wikipedia.org/wiki/Tor
