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 Windows 9x 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.
