Point-to-Point Tunneling Protocol (PPTP) is an alternative to L2TP/IPSec. Like L2TP/IPSec, PPTP provides
a logical transport mechanism to send PPP frames as well as tunneling or encapsulation so that the PPP
frames can be sent across an IP network. PPTP relies on the PPP connection process to perform user
authentication and protocol configuration.
With PPTP, data encryption begins after PPP authentication and connection process is completed. PPTP
connections use Microsoft Point-to-Point Encryption (MPPE), which uses the Rivest-Shamir-Aldeman
(RSA) RC-4 encryption algorithm. PPTP connections require user-level authentication through a PPP-based
authentication protocol (MSCHAPv2 is the currently-supported method).
The PPTP page displays all PPTP profiles that are currently configured for use by VPN services. This page
lists the PPTP profile names, the VPN Services that reference these PPTP profiles, and the folder for each
PPTP profile. Click Add to create a new PPTP profile, or click the pencil icon next to an existing profile to
edit that profile. The Add/Edit Details page appears.
The
Advanced Services > VPN Services > PPTP Add/Edit Details page contains the following fields, as
