Pop Quiz: Windows Server 2012 R2 DirectAccess Using Teredo

Applies to the "Design and implement network access services" objective of Exam 70-413.

Q: A company's IT team is planning to deploy to DirectAccess using Teredo. The team needs to know the server and client requirements.

Which of the following is required for the DirectAccess server to use Teredo?

  1. An IPv4 intranet address
  2. Two Internet consecutive Ipv4 addresses
  3. An IPv6 intranet address
  4. An IPv6 Internet address


Answer is B. The DirectAccess server requires two consecutive public IPv4 addresses so that it can act as a Teredo server and Windows-based clients can use the DirectAccess server to detect the type of NAT device that they are behind.

Quick Tip: You cannot use Teredo if the DirectAccess server has only one network adapter.
