## Remote-Access Software

Windows NT comes with a dial-up client and server, basic routing capability, and Virtual Private Network (VPN) support. Most of these are add-ons to UNIX and require integration with other UNIX services. Microsoft Windows NT Workstation performs as a Remote Access Service (RAS) client or as a RAS server for a single client. Microsoft Windows NT Server also performs as a client and supports up to 256 RAS clients in a server role. Windows NT Server comes with the Routing Information Protocol (RIP) and RAS. In addition, there is an add-on Routing and Remote Access Service (RRAS) that adds the Open Shortest Path First (OSPF) protocol and enhances RIP support. VPNs can be created among Windows NT Servers or other devices that speak the point-to-point tunneling protocol (PPTP). Routing and RAS adds support for dedicated VPNs over permanent connections among Windows NT servers. Microsoft Windows NT® 5.0 supports the L2TP protocol allowing increased interoperability with dedicated routers and access servers such as those made by Cisco.
