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

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.
