Wireless Network Tutorial

A VPN network (virtual private network) is private network that uses a public network such as the internet to connect users together as opposed to a direct connection. Common uses are employees who might use a company LAN at the corporate location to access company systems from home or a remote location whilst out in the field. VPN home networks are often used by corporate executives to gain access to company documentation whilst working from home.

VPN networks comprise a client server structure whereby the client is authenticated, data encrypted and sessions managed via tunneling. Despite the fact that VPS data travels across a public network such as the internet, encryption standards are utilized to prevent third party access and listening to the data. Up until a few years ago, VPN server hardware was cost prohibitive. Now, however, the network industry provides VPN servers built into some broadband routers. Microsoft server software such as Windows 2000 Server, Windows 2003 Server and Windows 2008 server (in beta testing) have built in VPN capability.

A VPN windows network can be setup using Windows Server products. The Microsoft website provides detailed information including: a VPN overview, step by step guides, how to connect remote users and resources for deploying remote access VPN's. You can also purchase a book online which provides tips, advice and walk through instructions for setting up a VPN windows network.

The Benefits of VPN Networks For Business

Cost: As a cost alternative, VPN networks can save businesses money on hardware and support services. Historically, organizations have been required to rent network facilities such as leased lines and incur long distance telephone charges. VPN technology replaces the need for remote access servers and long distance dial up networks. VPN networks allow organizations to use public network infrastructure thereby reducing the overall cost. Setup services can also be outsourced saving the company on the need to provide support personnel.

Scalability: Organizations that experience growth under the traditional access methods would be required to service the costs associated with infrastructure and dedicated lines for each new location. VPN's avoid these costs by tapping into existing public infrastructure. VPN's can bridge connections for enterprise offices, home based setups and mobile or remote workers.

Setting up VPN networks requires a good understanding of security and network installation. This includes an awareness of compatibility issues that can arise with different vendor and hardware solutions. This is particularly important for wireless VPN networks where security is paramount.
