A Virtual Private Network (VPN) is designed to extend a private network over a public one. It allows a network-enabled device, such as a computer or tablet to send and receive data across a public network as though it were directly connected to that network.
Benefits of a VPN
- Cutting your budget: A VPN can save you money by eradicating the need for long distance lines and phone service.
- Scalability: Because a VPN taps directly into the public lines, it provides a better service and greater scalability than a dedicated private network because the cost will not increase exponentially as your enterprise grows.
- Ease of use: When a VPN is set up correctly each client who has the appropriate networking and hardware support can use it as needed. VPN is also compatible with Wi-Fi local area networking.
VPN and Firewalls
A firewall is a network security system that is designed to block viruses, worms and hackers from invading via the Internet. When you are creating a VPN, you have two options for your server placement.
VPN in front of the firewall
In this case the firewall is between the VPN server and the Internet. This configuration is used in perimeter networking, where there is also a firewall between the VPN server and the intranet.
VPN behind the firewall
In this case the VPN server is between the firewall and the Internet.
