DirectAccess , also known as Unified Remote Access, is a VPN technology that provides intranet connectivity to client computers when they are connected to the Internet. Unlike many traditional VPN connections, which must be initiated and terminated by explicit user action, DirectAccess connections are designed to connect automatically as soon as the computer connects to the Internet. DirectAccess was introduced in Windows Server 2008 R2 , providing this service to Windows 7 and Windows 8 "Enterprise" edition clients. In 2010, Microsoft Forefront Unified Access Gateway (UAG) was released, which simplifies the deployment of DirectAccess for Windows 2008 R2, and includes additional components that make it easier to integrate without the need to deploy IPv6 on the network, and with a dedicated user interface for the configuration and monitoring. Some requirements and limitations that were part of the design of DirectAccess with Windows Server 2008 R2 and UAG have been changed (see requirements below). While DirectAccess is based on Microsoft technology, third-party solutions exist for accessing internal UNIX and Linux servers through DirectAccess. With Windows Server 2012 , DirectAccess is fully integrated into the operating system, providing a user interface to configure and native IPv6 and IPv4 support.

This technology encapsulates the IPv6 traffic over IPv4 to be able to reach the intranet over the Internet, which still ( mostly ) relies on IPv4 traffic. All traffic to
20-480: The intranet is encrypted using IPsec and encapsulated in IPv4 packets (if a native IPv6 connection cannot be established), which means that in most cases, no configuration of firewalls or proxies should be required. A DirectAccess client can use one of several tunneling technologies, depending on the configuration of the network the client is connected to. The client can use 6to4 , Teredo tunneling , or IP-HTTPS , provided
25-461: The server is configured correctly to be able to use them. For example, a client that is connected to the Internet directly will use 6to4, but if it is inside a NATed network, it will use Teredo instead. In addition, Windows Server 2012 provides two backward compatibility services DNS64 and NAT64 , which allows DirectAccess clients to communicate with servers inside the corporate network even if those servers are only capable of IPv4 networking.
