What Are The Available Options for Creating a Virtual Private Network?

The remote access of the information or files between the employees and colleagues of a company or a business has been made possible with the virtual private network. Therefore, VPN has become a necessity for the users of a business instead of a luxury. It is possible to get direct access to a remote server, but it has certain drawbacks. With your location different from the location of the remote server, you need to pay charges for long distance and at a time multiple modems and phones lines will be required for accommodating more than one connection. Hence, along with the other available options, VPN has proved to give the best solution to the business users.

VPN – Solution to Business Users

VPN offers the most cost effective solution and the connection is created through the public network with the use of tunneling protocols by VPN technologies. The privacy is provided by the encryption protocols that allow the users to access the company’s network through the VPN server. Some of the users may wonder how to choose the VPN technology. At present, four VPN protocols are more popular and each of these protocols has their pros and cons.

Options for Creating VPN

The most common available options and methods that are generally used for creating a virtual private network include PPTP, L2TP, IPSec and SSL. PPTP and L2TP are more familiar with the Windows admin, while IPSec and SSL are less familiar as compared to the former two options. To deploy a VPN server or gateway, the first step is to select the type of technology that should be used. It is important to get knowledge and information about the different options and get familiar with the characteristics and the needs of the users.

  • PPTP (Point to Point Tunneling Protocol) – Among the clients of Windows, it is the most widely supported method for VPN that was developed by Microsoft. Relatively, it has low overhead, but it does not provide encryption.
  • L2TP (Layer 2 Tunneling Protocol) – This protocol offers many advantages over PPTP. It can be used on networks that do not use IPs and further provide data integrity.
  • IPSec – It is used as a tunneling protocol for standard solution of VPN. This VPN works only with the networks based on IP and secures the transmitted packets in the tunnel mode.
  • SSL (Secure Sockets Layer) – This VPN technology is getting popular because of the advantage that no special software is required by the VPN clients.

Factors for Selecting the Best Option

In order to select from the available options, you need to consider some factors to make the best decision for your company or business because there is not one solution that can fit all the needs of an organization. Therefore, a few basic factors that need to be considered for selecting the VPN technologies include the deployed operating systems of the client and server, administrative overhead, resources of the network for which access is needed, performance issues, and required level of security.
