* Improved power management - preferences setting allows VPN to pause in a low-power state whenever screen is blanked or network is unavailable.

*Supports hardware-backed keystores (such as on the Nexus 7)
*Support for multi-factor authentication using OpenVPN static and dynamic challenge/response protocols.

You need root, busybox, tun.ko and the openvpn binary!

Features: UI similar to Wi-Fi settings; Restart tunnel when connectivity changes (e.g. from wifi to 3g); Start on boot; Passphrase; DNS; Script-Security; Write and View Log File; Open Source (GPLv3);

The prerequisites screen will check your device for root, busybox, tun.ko and the openvpn binary! This should be useful to new users figuring out what's needed to get openvpn running.

A working openvpn config is required.

You need a root device the tun/tap driver and busybox.

OpenVPN Installer will try to install openvpn (2.1.1) in /system/xbin or /system/bin. Your mileage might vary depending on your phone.

Androids ifconfig implementation fails to configure the tunnel device correctly. So you need ifconfig provided by busybox. Try a BusyBox Installer from the market.

The path to ifconfig is a compile time option to openvpn and can not be changed at runtime. This installer includes multiple binaries with preconfigured ifconfig locations.

The preferred way to install openvpn is to put busybox at /system/xbin/busybox and then choose openvpn preconfigured for '/system/xbin/busybox ifconfig'.

Finally /system/xbin/bb is not needed anymore! I hope this update makes live easier for some of you.

EDITORIAL REVIEWS

"Private Internet Access, one of Lifehacker readers' favorite VPN service providers, makes it easy to surf privately and securely from anywhere." -- Lifehacker

"There have been several Editors' Choice VPN services recently, as one product tops the next, but Private Internet Access out-performs and out-features the competition. With 4.5 stars, Private Internet Access sets the bar high and is truly the Editors' Choice, trumping all our previous favorites." -- PC Magazine

GENERAL NOTES
* Application is available for Android 4.0+ with Direct VPN Support
* Application is available for Android 2.0+ as a shortcut to the VPN Settings

This application installs OpenVPN 2.1.1 into /system/bin, /system/xbin or /system/xbin/bb after checking if a suitable BusyBox installation is available. It also symlinks ifconfig and route to /system/xbin/bb if necessary.

To use OpenVPN you will also need the TUN/TAP kernel module (tun.ko), which is not installed by this application.

Since some other OpenVPN binaries and installers didn't work for me, I decided to write my own installer. This installer checks some prerequisites and warns if some are missing.

Private Tunnel for Android is a new approach to true Internet security that creates a Virtual Private Network, a VPN that encrypts, hides and protects your Internet traffic.

Private Tunnel uses the official 4.0+ VPN API, so it does not require a rooted device.

VPN One Click(Free)
Unlimited Time,Unlimited Bandwidth and the best thing--->Free!
Android4+don't need root!facebook£¬twitter,youtube,google+,gmail,google map work in any places!
As a business grows, it might expand to multiple shops or offices across the country and around the world. To keep things running efficiently, the people working in those locations need a fast, secure and reliable way to share information across computer networks. In addition, traveling employees like salespeople need an equally secure and reliable way to connect to their business's computer network from remote locations.
One popular technology to accomplish these goals is a VPN (virtual private network). VPN One Click(Free) can provide a private network that uses a public network (usually the Internet) to connect remote sites or users together. The VPN uses "virtual" connections routed through the Internet from the business's private network to the remote site or employee. By using a VPN, businesses ensure security -- anyone intercepting the encrypted data can't read it.
VPN One Click(Free) was not the first technology to make remote connections,but we are trying our best! Several years ago, the most common way to connect computers between multiple offices was by using a leased line. Leased lines, such as ISDN (integrated services digital network, 128 Kbps), are private network connections that a telecommunications company could lease to its customers. Leased lines provided a company with a way to expand its private network beyond its immediate geographic area. These connections form a single wide-area network (WAN) for the business. Though leased lines are reliable and secure, the leases are expensive, with costs rising as the distance between offices increases.
Today, the Internet is more accessible than ever before, and Internet service providers (ISPs) continue to develop faster and more reliable services at lower costs than leased lines. To take advantage of this, most businesses have replaced leased lines with new technologies that use Internet connections without sacrificing performance and security. Businesses started by establishing intranets, which are private internal networks designed for use only by company employees. Intranets enabled distant colleagues to work together through technologies such as desktop sharing. By adding VPN One Click(Free), a business can extend all its intranet's resources to employees working from remote offices or their homes.

With only one tap, you can access Twitter, Facebook, Youtube and all the Internet without restriction in China.
