Infrastructure Planning: Direct Access

Open Beta for IPD Guide—Now Available for Download


The Infrastructure Planning and Design team is working on a new guide: DirectAccess. Get the beta by visiting the Connect Web site at

This IPD guide provides actionable guidance for designing a DirectAccess infrastructure. The guide’s easy-to-follow, four-step process gives a straightforward explanation of the infrastructure required for clients to be connected from the Internet to resources on the corporate network, whether or not the organization has begun deploying IPv6.

The guide covers four key steps in the design process for DirectAccess:

  • Aligning the project scope with the business requirements.
  • Determining whether IPv6, Teredo, 6to4, and IP-HTTPS connectivity will be supported for Internet-based clients.
  • Assessing the need for IPv6 transition technologies including NAT-PT and ISATAP for internal communication.
  • Determining the number and placement of servers, the certificate services requirements, and location of CRL distribution points.


Infrastructure Planning and Design streamlines the planning process by:

· Defining the technical decision flow through the planning process.

· Listing the decisions to be made and the commonly available options and considerations.

· Relating the decisions and options to the business in terms of cost, complexity, and other characteristics.

· Framing decisions in terms of additional questions to the business to ensure a comprehensive alignment with the appropriate business landscape.
