Microsoft Windows 2000-based virtual private networking (VPN) supports internet-industry standards technology to provide customers with an open interoperable VPN solution. Microsoft is committed to IETF (Internet Engineering Task Force) standards-track-based technology such as Internet Protocol Security (IPSec) and Layer 2 Tunneling Protocol (L2TP) as well as Point-to-Point Tunneling Protocol (PPTP)a proven published informational RFC that is supported in multiple interoperable third-party products.

  • PPTP provides simple-to-use, lower-cost VPN security. Unlike IPSec technology, PPTP is compatible with Network Address Translators (NAT) and supports both multi-protocol and multicast environments. It also combines standard user password authentication with strong encryption without requiring the complexity and expense of public key infrastructure (PKI).

  • IPSec provides advanced security for VPN but was not designed to address critical remote access requirements such as User Authentication and Address Assignment. In addition, it does not support multi-protocol or multicast (including some routing protocols). It is applicable primarily to IP-only, unicast-only situations.

  • L2TP in combination with IPSec is the onlystandards-track technology that addresses these remote access VPN requirements while leveraging IPSec for encryption. L2TP currently retains the same IETF standards-track status as IPSec.

  • Third-party IPSec-only implementations that do not use L2TP with IPSec are using non-standard proprietary technologies that can lock customers into closed solutions.
