• VPN (PPTP) - PPTP (Point-to-Point Tunneling Protocol) is a network protocol that
enables the secure transfer of data between a remote computer (in this case the thin
computer) and an enterprise server environment by creating a virtual private network
(VPN) across TCP/IP-based data networks such as the Internet. It provides a
password-protected path through the enterprise firewall to the enterprise server
environment in which the network and session services required thin computers reside.
The New Connection Wizard can be used (available from Network Connections in the
Control Panel) to configure and invoke a VPN connection.
An Internet Service Provider (ISP) must be available to provide access to the Internet.
Any of the standard means of connecting to the ISP may be used, such as a dial-up
modem, cable modem, and DSL modem. The connection to the ISP must be
established first, before contacting the enterprise PPTP VPN server. This includes
dial-up access as well as direct access through the cable modem and DSL modem
paths. For more information on the New Connection Wizard, refer to documentation on
the Microsoft Web site at:
http://www.microsoft.com.
Note
More information about setting up access to the enterprise servers is
available in the thin computers’ operating system documentation,
