Microsoft introduced DirectAccess technology in Windows server 2008R2 wherein we can connect directly to our corporate resources without the need of any VPN software. Particularly, DirectAccess configuration is pushed to the client machines through a set of group policies. Once these group policies have been applied on all Windows 7 domain joined machines, these machines can then connect remotely to the corporate network without dialing in to any VPN server.
Although, it sounds a great solution from the description it’s not easy to deploy though. The major requirement for DirectAccess is the IPv6 connectivity within the internal network.
