VPN Remote Access- Access from Anywhere

by Samuel Lucas Internet Business Expert.

VPN (virtual private network) is commonly a set of two or more computers that are connected to a private network which transmits over a public network in a very secure manner. Through VPN remote access using commercial internet service providers, one can securely connect to network resources from distant locations like home, conferences, hotels and so on.

VPNs may exist between client-to-server/remote access and site-to-site. If we talk about site to site virtual private networks, these involve the usage of dedicated VPN hardware at every remote site. However, VPN remote access employs central site VPN concentrator as well as software VPN client. The client is set up on the computer of the user and allows the user to set up secure and encrypted tunnel to network of workplace.

The virtual private network connection stretches the limits of the physical network. Machines capable of deriving access to VPN have capability to access almost all of the resources of private network in a manner of connected to it physically. It is allowed for the employees, external vendors, consultants as well as offshore support to stay connected to the corporate network from anywhere to perform their job without any inconvenience. There is a limit for the number of simultaneous VPN connections by the public network bandwidth as well as execution capabilities of VPN server.

Virtual private networks supply encoding and extra security measures to assure the access to network and data only to authorized users. As VPN is secure mode to allow users access to a private network remotely and most of the time it is cost-effective and quicker as compared to old dial-up connections, virtual private networks are commonly used when remote users need to access to network resources securely that is not possible by any other mean. For instance, virtual private networks make the administrator able diagnosing and solving the problems as well as operating management tasks while being miles away from the network physically. Other than this, remote users can also take benefit of a virtual private network which permits access to shared network and fax printers.
