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-660HN-T1A SUA case. 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-660HN-T1A to forward to
the appropriate private IP address of Windows NT server.
