Routing and Remote Access Service (RRAS)
Updated: July 16, 2014
The Routing and Remote Access service (RRAS) supports remote user or site-to-site connectivity by using virtual private network (VPN) or dial-up connections.
In addition to this topic, the following RRAS documentation is available.
RRAS provides the following features.
RRAS Multitenant Gateway. If you are using Hyper-V Network Virtualization or you have VM networks deployed with VLANs, you can deploy RRAS as a virtual machine (VM)-based software gateway and router that allows Cloud Service Providers (CSPs) and Enterprises to enable datacenter and cloud network traffic routing between virtual and physical networks, including the Internet. With the RRAS Multitenant Gateway, tenants can VPN to their VM network resources in the datacenter from anywhere. You can also provide tenants with site-to-site VPN connections between their remote sites and your datacenter. In addition, you can configure the RRAS Multitenant Gateway with Border Gateway Protocol for dynamic routing, and you can enable Network Address Translation (NAT) to provide Internet access for VMs on VM networks.
The RRAS Multitenant Gateway is available only in Windows Server 2012 R2. It is not available in Windows Server® 2012.
Remote Access. By using RRAS, you can deploy VPN connections to provide end users with remote access to your organization's network. You can also create a site-to-site VPN connection between two servers at different locations.
Routing. RRAS is a software router and an open platform for routing and networking. It offers routing services to businesses in local area network (LAN) and wide area network (WAN) environments or over the Internet by using secure VPN connections. Routing is used for multiprotocol LAN-to-LAN, LAN-to-WAN, VPN, and network address translation (NAT) routing services.
