It will review the author’s thoughts of how to use VPN in a common workplace.

Then it will show you how to implement VPN on a network, through both hardware and software installations. You will see how employees collaborate with this tool and use it to increase productivity. You will see the obstacles that you would encounter with a VPN system and how to overcome those obstacles and solve problems that might occur in its everyday use.
