VPN softwares

VPN Software helps you to connect to the internet with the help of its easy to use interface. VPN service providers nowadays either offer their own client software or integrate the capabilities of Overplay VPN to help their customers allow easy approachability to internet while being hidden. In both the cases, these software are of much help and make it far easier to connect to the www than doing it manually.

VPN softwares are widely used to establish remote connections between two geographically separated locations. This can take the form of a connection between two fixed sites, in which the VPN is stateful and the connection is permanent, usually requiring client software on both sides.

Alternately, VPN software can facilitate a connection between a fixed site and multiple temporary sites, such as when an e-commerce company wishes to establish a secure connection between itself and a client for the purpose of making a single transaction.

Software available is plentiful, inexpensive and relatively easy to set up and maintain. OpenVPN Technologies has a set of VPN offerings to provide highly callable and reliable communications services. The open source product is a de facto standard and is widely used. The company offers both a server product and a hosted service. The OpenVPN Access Server, an SSL VPN software package, can be used in Windows, Mac, and Linux environments, and can accommodate remote access to internal network or private cloud resources, with fine-grained access control. The OpenVPN Hosted Service is an SSL VPN service offering the OpenVPN Server capabilities as a cloud service offering. Also available is the OpenVPN Access Server Virtual Appliance, an SSL VPN virtual appliance with the same capabilities.

Most of the VPN vendors have their own client software through which they provide capable services to their customers. A prominent name in this context is Overplay VPN. The firm offers extended support for the known protocols such as PPTP, L2TP and OpenVPN through its feature rich and robust VPN client software. Depending on the package you buy from the company, you will be entitled to use the services of related protocol by selecting the server locations currently supported by it.


The software possesses an appealing interface and is laced with all the useful capabilities that is desired in an upmarket VPN client. It is safe, secure and duly encrypted. In addition, it allows to see your account details, checkout your IP address, know about the VPN provider and issues related to its services in detail in its knowledge base and FAQ sections, and so on. This is however one single example where a VPN service provider ofers its own client software, there are many more in the market.


Windows shops have an easy option with the point-to-point tunneling protocol (PPTP), which ships with Microsoft Windows. The protocol for implementing VPNs doesn’t by itself describe any encryption or authentication features, but instead implements security by the PPP protocol that is being tunneled. The PPTP that ships with Windows however, does offer different levels of authentication and encryption as a standard feature of the PPTP stack. It offers security equivalent to any other VPN product. All recent versions of Windows include a PPTP client, which is limited to two concurrent outbound connections. Linux distributions also recently started supporting PPTP, as has the Mac OS X.

An alternate tunneling protocol is L2TP (layer 2 tunneling protocol). L2TP by itself does not provide for encryption or confidentiality. However, it is used in conjunction with IPSec, which is more secure. Once the connection is established, the L2TP packets are encapsulated by IPSec. The L2TP packets are therefore hidden within the IPSec packet, so the encrypted packet can reveal no information to any potential intruders about the internal network.
