Virtual private network technology is based on the idea of tunneling. VPN tunnel involves establishing and maintaining a logical network connection (that may contain intermediate hops). On this connection, packets constructed in a specific VPN protocol format are encapsulated within some other base or carrier protocol, then transmitted between VPN client and server, and finally de-encapsulated on the receiving side.
VPN supports two types of  VPN Tunnel – voluntary and compulsory. Both types of tunneling are commonly used.

Involuntary tunneling

The VPN client manages the connection setup. The client first makes a connection to the carrier network provider (an ISP in the case of Internet VPNs). Then, the VPN client application creates the tunnel to a VPN server over this live connection.
In compulsory tunneling, the carrier network provider manages VPN connection setup. When the client first makes an ordinary connection to the carrier, the carrier in turn immediately brokers a VPN connection between that client and a VPN server. From the client point of view, VPN connections are set up in just one step compared to the two-step procedure required for voluntary tunnels.

Compulsory VPN tunnel

Authenticates clients and associates them with specific VPN servers using logic built into the broker device. This network device is sometimes called the VPN Front End Processor (FEP), Network Access Server (NAS) or Point of Presence Server (POS). Compulsory VPN tunnel hides the details of VPN server connectivity from the VPN clients and effectively transfers management control over the tunnels from clients to the ISP. In return, service providers must take on the additional burden of installing and maintaining FEP devices.

VPN Tunnel Protocols

Several computer network protocols have been implemented specifically for use with VPN tunnels. The three most popular VPN tunneling protocols listed below continue to compete with each other for acceptance in the industry. These protocols are generally incompatible with each other.

Point-to-Point Tunneling Protocol (PPTP)

Several corporations worked together to create the PPTP specification. People generally associate PPTP with Microsoft because nearly all flavors of Windows include built-in client support for this protocol. The initial releases of PPTP for Windows by Microsoft contained security features that some experts claimed were too weak for serious use. Microsoft continues to improve its PPTP support, though.

Layer Two Tunneling Protocol (L2TP)

The original competitor to PPTP for VPN tunneling was L2F, a protocol implemented primarily in Cisco products. In an attempt to improve on L2F, the best features of it and PPTP were combined to create a new standard called L2TP. Like PPTP, L2TP exists at the data link layer (Layer Two) in the OSI model — thus the origin of its name.

Internet Protocol Security (IPsec)

IPsec is actually a collection of multiple related protocols. It can be used as a complete VPN protocol solution or simply as the encryption scheme within L2TP or PPTP. IPsec exists at the network layer (Layer Three) of the OSI model.

VPN Tunnel Features:

  • Surf anonymously and safely with our encrypted VPN service: When you connect to our servers, all your traffic is protected by our powerful encryption. Furthermore, we swap your IP address with a new, anonymous IP address that belongs to VPN tunnel.
  • Don’t let your IPS track your internet activity: Unlike other VPN providers, we don’t store any traffic logs so you can use the internet freely without having to worry about your online activities being tracked by your ISP or government organizations.
  • Download as much as you want without worry about being cut off: They don’t place download limits or speed limits on our VPN connections. You are free to download as much as you want a full speed with our huge network of Gb/s servers.
  • Many countries block or censor certain websites: If you find yourself in such a country, you can bypass these blocks by connecting to our VPN tunnel. This allows you direct access to the entire internet.
  • A lot of web services have limited access in certain countries: One example is the BBC iPlayer, which only streams content within the UK. VPN tunnel provides IP addresses in a variety of different countries, so you don’t have to be limited by your geographical location when you are online.
  • Easily bypass VoIP blocks to access Skype wherever you are: This is one of the biggest advantages of using a VPN tunnel, compared to a VPN proxy or other solutions. A VPN tunnel will channel ALL your traffic, with no exceptions. That includes protocols such as www, ftp, VoIP, torrents and all the others.
  • Use your favorite P2P applications: P2P enabled in many locations (as many as we can) – your peering activity won’t be tracked by private or government agencies

Connect to our VPN tunnel using a smartphone or tablet couldn’t be easier.

Using the PPTP protocol, all you need to do is access the device’s network settings. In other words, no downloading software to your device before getting started. Control panel contains easy to follow guides for what you need to do.

Nowadays, there are more and more services for smartphones and tablets, and as these increase, so too do the risks of sensitive information landing in the wrong hands. Information like banking and login details, photo albums, calendars, and so on.

If you connect your smartphone or tablet to VPN tunnel, all the traffic flowing between your device and our servers will be encrypted. This reduces the risk of your data ending up anywhere else other than where it’s meant to go.
