Microsoft DirectAccess – Windows server 2008 R2 with Windows 7

Microsoft’s is connecting Windows 7 and Windows Server 2008 R2 for connect-anywhere access using DirectAccess technology

DirectAccess is a way for Windows 7 clients to securely connect the corporate network from any location without  any traditional VPN. It encrypts bidirectional connection between the enterprise domain and the client device prior to the user logging on to the system, allowing admins to manage the remote machine via Group Policy and it physically connected to the network and always stays on. This is very useful for network administrator to troubleshoot the server. Greater functionality means greater hardware and software requirements.

The following list of DirectAccess requirements comes directly from Microsoft TechNet:

One or more DirectAccess servers running Windows Server 2008 R2 with two network adapters:
One connected directly to the Internet, and a second connected to the intranet.
On the DirectAccess server, at least two consecutive, public IPv4 addresses assigned to the network adapter that’s connected to the Internet.

DirectAccess clients running Windows 7.
At least one domain controller and DNS server running Windows Server 2008 SP2 or Windows Server 2008 R2.
A public key infrastructure (PKI) to issue computer certificates to the protection for traffic.

IPv6 transition technologies available for use on the DirectAccess server: ISATAP, Teredo, and 6to4. Optionally, DirectAccess runs over IPv6 and only connects to Windows Server 2008 R2 or Windows Server 2008 with SP2 and most of the network are still on IPv4. In order for DirectAccess to communicate over the Internet, bridging protocols such as 6to4 or Teredo have to be used to encapsulate IPv6 packets over any IPv4 medium or network device.
