  A US VPN allows you to browse the Internet securely and access sites restricted to American IPs. It is important to select a VPN provider that won't limit your speed or transfer volume and that doesn't charge for switching between VPN server locations. For example, some American VPN services own and manage all their software and hardware. Features such as these should be considered when selecting a VPN provider that meets your needs. Benefit form Worldwide Server Locations Top Tier US VPN providers will maintain servers outside of America, such as Europe and Asia. These providers allow the user to view the internet as if they are located in any of those locations.
  
  Overview - This article discusses some essential technical concepts associated with a VPN. A Virtual Private Network (VPN) integrates remote employees, company offices, and business partners using the Internet and secures encrypted tunnels between locations. The remote workstation or laptop will use an access circuit such as Cable, DSL or Wireless to connect to a local Internet Service Provider (ISP). With a client-initiated model, software on the remote workstation builds an encrypted tunnel from the laptop to the ISP using IPSec, Layer 2 Tunneling Protocol (L2TP), or Point to Point Tunneling Protocol (PPTP). Once that is finished, the ISP builds an encrypted tunnel to the company VPN router or concentrator. TACACS, RADIUS or Windows servers will authenticate the remote user as an employee that is allowed access to the company network. Remember that there is no way to plan for everything when it comes to VPN so reading about other people's experiences will help you find information such as service reliability, promotions, and security straight from the perspective of the user. Your best VPN should have the backing of many other users, not just a select few who have very narrowed specifications and requirements. It also isn't always the most expensive, not necessarily the fastest, or the most sophisticated. Tailor your chosen services to your exact needs so you can maximize what you are getting from the company without paying too much. To do this, make sure to run through a list of your basic expectations before narrowing your list further a few brands. From there, you can then begin the more detailed task of comparing offers and prices and specifications until you come up with the best VPN service that suits your needs just right. (b) If you receive a "Request Timed Out" error message, the Contivity VPN Switch is probably not available, and you should contact your Network Administrator. If you keep getting this message and are unable to connect, then it may indicate that the Contivity VPN Switch is unable to communicate with the client because it is behind some kind of NAT (Network Address Translation) device. NAT (Network Address Translation) Traversal allows a number of devices on a private network to access the Internet simultaneously without each requiring its own external IP address. Most hotels and airports that provide Internet connectivity use NAT to connect to the Internet. Q6 Error Message Cannot Alter Routing Table - Cause Message means the you the user, an application on your machine, or your ISP attempted to change the routing table via an ICMP redirect attempt and it was not successful.
