Single Interface DirectAccess/VPN Deployments 6 Single Site Vs. Multisite Deployment 8 Conclusion 9 2 White Paper F5 and Windows Server 2012 Direct Access/Remote Access Services Introduction For Windows 8 and Windows Server 2012, Microsoft has taken two remote access technologies found in previous versions of Windows Server, DirectAccess and VPN Server, and pulled them under the same management umbrella called simply Remote Access. F5 technologies can be deployed to manage traffic and balance loads on these services. Originally introduced in Windows Server 2008 R2 and Windows 7, DirectAccess shifted previous remote access technology. Unlike traditional VPNs, in which connections have been manually initiated at the user level, DirectAccess makes use of a seamless, system-level connection. This means that remote, domain-joined systems will automatically and securely build a corporate network presence upon boot. VPN, formerly known as Remote Access Services (RAS), was introduced in Windows NT and includes the traditional Windows VPN technologies, including IKEv2, SSTP, PPTP, and L2TP. Windows Server 2012 customers can deploy DirectAccess, VPN, or both, and it is often beneficial to deploy both.
