Configure a PPTP server behind SUA

Introduction
PPTP is a tunneling protocol defined by the PPTP forum that allows PPP packets to be encapsulated within Internet
Protocol (IP) packets and forwarded over any IP network, including the Internet itself.
In order to run the Windows9x PPTP client, you must be able to establish an IP connection with a tunnel server such as
the Windows NT Server 4.0 Remote Access Server.
Windows Dial-Up Networking uses the Internet standard Point-to-Point (PPP) to provide a secure,optimized multiple-
protocol network connection over dial-up telephone lines. All data sent over this connection can be encrypted and
compressed, and multiple network level protocols (TCP/IP, NetBEUI and IPX) can be run correctly. Windows NT
Domain Login level security is preserved even across the Internet.

PPTP appears as new modem type (Virtual Private Networking Adapter) that can be selected when setting up a
connection in the Dial-Up Networking folder. The VPN Adapter type does not appear elsewhere in the system. Since
PPTP encapsulates its data stream in the PPP protocol, the VPN requires a second dial-up adapter. This second dial-up
adapter for VPN is added during the installation phase of the Upgrade in addition to the first dial-up adapter that provides
PPP support for the analog or ISDN modem.
The PPTP is supported in Windows NT and Windows 98 already. For Windows 95, it needs to be upgraded by the Dial-
Up Networking 1.2 upgrade.
