PPTP

The Point-to-Point Tunneling Protocol (PPTP)[1] is a method for implementing virtual private networks. Another method for VPN is OpenVPN.

PPTP implementation

  • PPTP works by sending a regular PPP session to the peer with the Generic Routing Encapsulation (GRE) protocol. A second session on TCP port 1723 is used to initiate and manage the GRE session. PPTP is difficult to forward past a network firewall because it requires two network sessions.
  • PPTP connections are authenticated with Microsoft MSCHAP-v2 or EAP-TLS. VPN traffic is optionally protected by MPPE encryption, which is described by RFC 3078.
  • MSCHAP-v2 can be compromised if users choose weak passwords. The certificate-based EAP-TLS provides a superior security option for PPTP.

Cisco first implemented PPTP and later licensed the technology to Microsoft. Mac OS X is bundled with a PPTP client. Palm PDA devices with Wi-Fi are bundled with the Mergic PPTP client. Microsoft Windows Mobile 2003 and higher also support the PPTP protocol.

PoPToP

Poptop[2], is a PPTP Server for Linux, ports also exist for Solaris 2.6, OpenBSD, FreeBSD and others, it features:

  • Microsoft compatible authentication and encryption (MSCHAPv2, MPPE 40 - 128 bit RC4 encryption)
  • Support for multiple client connections
  • Seamless integration into a Microsoft network environment (LDAP, SAMBA) using RADIUS plugin
  • Works with Windows 95/98/ME/NT/2000/XP PPTP clients
  • Works with Linux PPTP client
  • Poptop is free software, licensed under the terms of theGNU General Public License (GPL)

Installation

FreeLink

Requirements:

Use apt-get to install Poptop:

apt-get install pptpd webmin-pptp-server 

Then use the PPTP server configuration module for webmin to configure Poptop or you could configure it manually[3][4]
