Advanced Services > VPN Services > PPTP
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.
Select Add to create a new PPTP profile, or click the pencil icon next to an existing profile to edit. The Add/Edit
Details page appears.
The Advanced Services > VPN Services > PPTP Add/Edit Details page contains the following fields, as described
in Table 33.
