Understanding routing

The routing services included with Windows NT Server 4.0, MultiProtocol Routing (MPR) version 1.0, provided a limited set of LAN-based routing services suitable for smaller organizations and branch offices. In June 1996, Microsoft offered the Routing and Remote Access Service as a free download component from the Microsoft Web site. The Routing and Remote Access Service for Windows NT 4.0, also known as RRAS, integrated routing and remote access services, extended the internetworking and routing capabilities available in MPR 1.0, and enabled routing over WANs and dial-up links. Windows 2000 offered Routing and Remote Access, a new service distinct from RRAS, that included expanded dial-in and VPN networking capabilities. The version of Routing and Remote Access included with the Windows Server 2003 family extends the capabilities of the Windows 2000 Routing and Remote Access service with simplified configuration for demand-dial routing, dynamic as well as static packet filtering, IPSec translation over network address translation (NAT) interfaces, and many other features.
