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.
Configuration
This application note explains how to establish a PPTP connection with a remote private network in the Prestige
SUA case. In ZyNOS, all PPTP packets can be forwarded to the internal PPTP Server (WinNT server) behind
SUA. The port number of the PPTP has to be entered in the SMT Menu 15 for Prestige to forward to the
appropriate private IP address of Windows NT server.
Example
The following example shows how to dial to an ISP via the Prestige and then establish a tunnel to a private
network. There will be three items that you need to set up for PPTP application, these are PPTP server (WinNT),
PPTP client (Win9x) and the Prestige.
