VIRTUAL PRIVATE NETWORK SUPPORT
Your WireSpeed modem supports Virtual Private Networks (VPN). VPN allows users working at home or at an off-site
location to create a direct “tunnel” to a corporate LAN server. The VPN is a point-to-point connection between the user’s
computer and another network (usually a corporate LAN). This direct connection avoids much of the Internet congestion
and allows secure communication and encryption.
The WireSpeed modem VPN feature supports the PPP-to-PPTP relaying protocol. Settings for VPN must be made to both
sides of the VPN “tunnel” connection: the user PC and the corporate LAN server.
NOTE:
Before creating a VPN connection, you must have created a PPP account and established a PPP session.
VPN Requirements
To operate the VPN feature of your Westell modem, the following requirements must be met:
•
Service Provider.
Your service provider must provide the following:
– VPI/VCI values for PPP service
– User ID and password
If you already have DSL service, use your existing user ID and password.
•
Personal Computer.
Your computer must support Point-to-Point and Point-to-Point Tunneling Protocol (PPTP).
Please refer to your original operating system documentation to see if your PC supports these protocols.
•
Operating System.
Your Westell modem supports VPN on Windows 98, Windows Me, Windows 2000, and Windows
NT operating systems.
•
TCP/IP
. Prior to establishing PPTP tunnels, IP addresses must be properly configured at both ends of the PPTP tunnel.
This means both your PC and the PPTP server for your corporate LAN.
•
Corporate LAN
. Check with your corporate IT or LAN group to make sure that such connections are supported. You
will need the IP address or host name of the corporate LAN server.
