VPN Connect Your Office Globally

VPN stands for Virtual Private Network. If you have a local area network in your office, it is just an extension to your local area network. With this extension, you can login to your office local area network from any location in the world through the worldwide internet access points. Your branch office staff can access to your back end accounting and inventory system or your retail outlet can update daily sales data directly into the database managed by the head office.

Why should I need it?

By having users create VPN connections rather than dial-up connection, the company does not incur the considerable expenses associated with long distance telephone service without compromising security. It enables your qualified employee to manage your company core business application and database at one location centrally.

How it work?

A VPN connection includes the following components:

VPN server - A computer or VPN router that accepts VPN connections from VPN clients.
VPN client - A computer or VPN router that initiates a VPN connection to a VPN server.
Tunnel - The portion of the connection in which your data is encapsulated.
VPN connection - The portion of the connection in which your data is encrypted. For typical secure VPN connections, the data is encrypted and encapsulated along the same portion of the connection.
Tunneling protocols - Protocols that are used to manage tunnels and encapsulate private data. Data that is tunneled must also be encrypted to be a VPN connection
Tunneled data - Data that is usually sent across a private point-to-point link.
Transit internetwork - The shared or public network crossed by the encapsulated data.

You can configure Win2003 server standard edition as VPN router. It can accept up to 1,000 concurrent VPN connections. If 1,000 VPN clients are connected, further connection attempts are denied until the number of connections falls below 1,000.
