title: Amazon VPC testing
body: <p>I sell a product that runs on Amazon EC2. A company now wants to purchase and install it within their perimeter... This also implies the use of a VPN connection to the EC2 datacenter. </p>
  
  <p>I want to test my product using Amazon VPN (VPC) before handing over the code. Must I change my code to make it work across VPC? If I run on Windows, then wants the quickest and easiest desktop VPN client avaialable that will allow me to connect across VPN to the Amazon datacenter?</p>
