P-660R-F1 Support Notes

PPTP appears as new modem type (Virtual Private Networking Adapter) that

can be selected when setting up a connection in the D ial-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.
