Prestige 2302RL Support Notes
Window98 PPTP Client / Internet / NT RAS Server Protocol Stack
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, 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 already supported in Windows NT and Windows 98. For Windows 95, a software upgrade with
Dial-Up Networking 1.2 is required.

Configuration
This application note explains how to establish a PPTP connection to a remote private network on the Prestige
with SUA enabled. In ZyNOS, all PPTP packets are forwarded to the internal PPTP Server (Windows NT
server) behind SUA. . You must specify the PPTP port number in SMT menu 15 for the Prestige to forward
the packets to the intended Windows NT server using the private IP address.
