P-660H-Tx v2 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, 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 P-660H-Tx v2 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 Web
Configurator, Advanced Setup,

Network -> NAT -> Port Forwarding

on

P-660H-Tx v2 to forward to the appropriate private IP address of Windows NT
server.
