The Infrastructure Planning and Design team is working on a new guide: DirectAccess. 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. While still at beta I would still recomend it as it is good prepparation.
