By now, most of us know what DirectAccess is. For those who don’t, Direct Access is a revolutionary VPN technology which was introduced in Windows Server 2008 R2. It provides seamless connectivity to corporate resources without requiring any dial-up or VPN. DirectAccess connectivity is based on IPsec, IPV6, and transition technologies like Teredo, 6to4, IP-HTTPS, and ISATAP. In DirectAccess, the IPv6 traffic is encapsulated in an IPv4 packet and is then sent across the internet, after which the DirectAccess server reads the IPv6 headers and executes it.

In our previous post at http://www.nappliance.com/blog/nappliance-nuag-and-directaccess-better-together we highlighted how UAG and DirectAccess are better together and the benefits of connecting through the DirectAccess. In this post we will concentrate on the advantages DirectAccess has over the traditional VPN connectivity and why companies would want to move away from the VPN infrastructure.
