{{Short description|Microsoft API and server software}}

'''Routing and Remote Access Service''' ('''RRAS''') is a Microsoft [[API]] and [[Server (computing)|server]] software that makes it possible to create applications to administer the [[Router (computing)|routing]] and remote access service capabilities of the [[operating system]], to function as a network router. Developers can also use RRAS to implement routing protocols. The RRAS server functionality follows and builds upon the [[remote access service|Remote Access Service]] (RAS) in [[Windows NT 4.0]].<ref name="RRAS MSDN Library">[http://msdn.microsoft.com/en-us/library/Aa446768 RRAS MSDN Library]</ref> RRAS was introduced with Windows 2000 and offered as a download for Windows NT 4.0.

==Overview==

# Multiprotocol [[Router (computing)|router]] - The computer running RRAS can route IP, [[IPX]], and [[AppleTalk]] simultaneously. All routable protocols are configured from the same administrative utility. RRAS included two unicast routing protocols, [[Routing Information Protocol]] (RIP) and [[Open Shortest Path First]] (OSPF) as well as [[Internet Group Management Protocol|IGMP]] routing and forwarding features for [[IP multicast]]ing.

RRAS was introduced with [[Windows 2000]] and offered as a download for Windows NT 4.0.

# [[Dial-on-demand routing|Demand-dial router]] - IP and IPX can be routed over on-demand or persistent [[Wide area network|WAN]] links such as analog phone lines or [[ISDN]], or over [[VPN]] connections.

# [[Remote access server]] - provides remote access connectivity to dial-up or VPN remote access clients that use IP, IPX, AppleTalk, or [[NetBEUI]].

Routing services and remote access services used to work separately. [[Point-to-Point Protocol]] (PPP), the protocol suite commonly used to negotiate point-to-point connections, has allowed them to be combined.

Routing and Remote Access Service (RRAS) can be used to create [[Client (computing)|client]] applications. These applications display RAS common [[dialog boxesbox]]es, manage remote access connections and devices, and manipulate phone-book entries.<ref name="RRAS Microsoft MSDN">[http://msdn.microsoft.com/en-us/library/bb545679(v=vs.85).aspx Routing and Remote Access Service MSDN]</ref>

==Routing and Remote Access Service Management Pack==

The Routing and Remote Access Service Management Pack helps a network administrator monitor the status and availability of computers running Windows Server 2008 R2.<ref name="RRAS Mgmt Pack Guide">[http://www.microsoft.com/downloads/en/details.aspx?FamilyID=785e5524-6228-45a9-b3e7-d85e48345a34&displaylang=e RRAS Management Pack Guide for System Center Operations Manager 2007]</ref>

==New Features introduced in Windows Server 2008==

#*Server Manager -– Application used to assist system administrators with installation, configuration, and management of other RRAS features.

#*[[Secure Socket Tunneling Protocol]]

#*VPN enforcement for [[Network Access Protection]] -– RestrictsLimits vpnVPN connections to only defined network services.

#*[[IPv6]] support -– added [[Point-to-Point Protocol|PPPv6]], [[L2TP]], [[DHCPv6]], and [[RADIUS]] technologies allowing them to work over IPv6.

#*New [[cryptographic]] support -– Strengthenedstrengthened [[encryption]] algorithms to comply with U.S. government security requirements., Inin addition to removing algorithms which could not be strengthened.<ref name="Whats New">[httphttps://technet.microsoft.com/en-us/library/cc730711(WS.10).aspx#BKMK_3 What's New in Routing and Remote Access in Windows Server 2008]</ref>
