Overview of the Test Lab Scenario

In this test lab scenario, DirectAccess is deployed with:

• DC1—A server that is configured as a domain controller, Domain Name System (DNS) server, and Dynamic Host Configuration Protocol (DHCP) server.
  
  
• EDGE1—A server on the internal network that is configured as the first Remote Access server in a Remote Access server cluster. This server has two network adapters; one connected to the internal network, and the other connected to the external network.
  
  
• EDGE2—A server on the internal network that is configured as the second Remote Access server in a Remote Access server cluster. This server has two network adapters; one connected to the internal network, and the other connected to the external network.
  
  
• APP1—A server on the internal network that is configured as a web and file server, and as an enterprise root certification authority (CA)
  
  
• APP2—A computer on the internal network that is configured as an IPv4 only web and file server. This computer is used to highlight the NAT64/DNS64 capabilities. This guide uses Windows Server 2003 SP2; however, you can use any computer that is configured as an IPv4 only computer.
  
  
• INET1—A server that is configured as an Internet DNS and DHCP server.
  
  
• NAT1—A client computer that is configured as a network address translator (NAT) device using Internet Connection Sharing.
  
  
• CLIENT1—A client computer that is configured as a DirectAccess client that will be used to test DirectAccess connectivity when moving between the internal network, the simulated Internet, and a home network.
  
  

The test lab consists of three subnets that simulate the following:

• A home network named Homenet (192.168.137.0/24) connected to the Internet by a NAT.
  
  
• The external network represented by the Internet subnet (131.107.0.0/24).
  
  
• An internal network named Corpnet (10.0.0.0/24; 2001:db8:1::/64) separated from the Internet by the Remote Access server.
  
  

Computers on each subnet connect using either a physical or virtual hub or switch, as shown in the following figure.
