PPTP Configuration

Overview

Point-to-Point Tunnelling Protocol (PPTP) is an encrypted VPN protocol like IPSec, although not as

secure as IPSec. PPTP does not support gateway to gateway connections and is only suitable for

connecting remote users. A PPTP Server can terminate PPTP connections from VPN clients, such as

those included with Windows 2000.

You can configure the X family to act as a PPTP Server for VPN termination that is compatible with

Windows PPTP VPN clients such as Windows 98 and Windows 2000. The PPTP Server function also

supports MPPE 128-bit encryption.

PPTP Status

You can view and manage PPTP connections and configuration from the PPTP Status page (VPN >

PPTP Status).

The following figure shows the PPTP Status page:
