Introduction

·         Improved Manageability of Remote Users. Without DirectAccess, IT professionals can only manage mobile computers when users connect to a VPN or physically enter the office. With DirectAccess, IT professionals can manage mobile computers by updating Group Policy settings and distributing software updates any time the mobile computer has Internet connectivity, even if the user is not logged on. This flexibility allows IT professionals to manage remote computers on a regular basis and ensures that mobile users stay up-to-date with security and system health policies.  

·         Secure and Flexible Network Infrastructure. Taking advantage of technologies such as Internet Protocol version 6 (IPv6) and Internet Protocol security (IPsec), DirectAccess provides secure and flexible network infrastructure for enterprises. Below is a list of DirectAccess security and performance capabilities:

Authentication. DirectAccess authenticates the computer, enabling the computer to connect to the intranet before the user logs on. DirectAccess can also authenticate the user and supports two-factor authentication using smart cards.

Encryption. DirectAccess uses IPsec to provide encryption for communications across the Internet.

Access to IPv4-only intranet resources. UAG SP1 RC DirectAccess extends the value of Windows DirectAccess with NAT64/DNS64, an IPv6/IPv4 protocol transition technology that enables DirectAccess client connectivity to IPv4-only resources on the intranet.

·         High availability and array configuration. UAG DirectAccess extends the value of Windows DirectAccess by adding integrated support for Network Load Balancing and array configuration, which work together to enable a highly available DirectAccess deployment.

·         IT Simplification and Cost Reduction. By default, DirectAccess separates intranet from Internet traffic, which reduces unnecessary traffic on the intranet by sending only traffic destined for the intranet through the DirectAccess server. Optionally, IT can configure DirectAccess clients to send all traffic through the DirectAccess server, which is referred to as Force Tunneling.

Important:

These instructions are designed for configuring a Test Lab using the minimum number of computers. Individual computers are needed to separate the services provided on the network, and to show clearly the required functionality. This configuration is not designed to reflect best practices, nor does it reflect a required or recommended configuration for a production network. The configuration, including IP address assignment and all other configuration parameters, is designed to work only on a separate Test Lab network. For more information on planning and deploying DirectAccess with Forefront UAG for your production network, please see the Forefront UAG DirectAccess design guide and the Forefront UAG DirectAccess deployment guide

Overview of the Test Lab scenario

• One computer running Windows Server 2008 R2 Enterprise Edition (DC1), that is configured as an intranet domain controller, Domain Name System (DNS) server, Dynamic Host Configuration Protocol (DHCP) server, and an enterprise root certification authority (CA).
• One intranet member server running Windows Server 2008 R2 Enterprise Edition (UAG1), that is configured as a Forefront UAG SP1 RC DirectAccess server.
• One intranet member server running Windows Server 2008 R2 Enterprise Edition (APP1) that is configured as a general application server and Network Location Server.
• One intranet member server running Windows Server 2003 SP2 Enterprise Edition (APP3), that is configured as a IPv4 only web and file server. This server is used to highlight the NAT64/DNS64 capabilities.
• One intranet member server running Windows Server 2008 R2 Enterprise Edition (TMG1), that is configured as a web proxy server for DirectAccess clients. Threat Management Gateway 2010 will be installed on TMG1 to provide web proxy services.
• One standalone server running Windows Server 2008 R2 Enterprise Edition (INET1), that is configured as an Internet DNS and DHCP server. INET1 will also be configured to provide Internet access to the live Internet.
• One standalone client computer running Windows 7 (NAT1), that is configured as a network address translator (NAT) device using Internet Connection Sharing (ICS).
• One roaming member client computer running Windows 7 Enterprise or Ultimate (CLIENT1) that is configured as a DirectAccess client.

• A home network named Homenet (192.168.137.0/24) connected to the Internet subnet by NAT1.
• The Internet subnet (131.107.0.0/24).
• An intranet subnet named Corpnet (10.0.0.0/24) separated from the Internet subnet by the Forefront UAG DirectAccess server.
• A “live” network connection that provides a path to your actual Internet gateway. INET1 will be connected to the Internet subnet and the “live” network connection so you can test actual Internet access when CLIENT1 is acting as a DirectAccess client.

·         Web proxy – You can configure the force tunneling DirectAccess clients on the Internet to use a web proxy on your intranet to gain Internet access. When using the web proxy option, the DirectAccess clients are limited to using web proxy supported protocols when connecting to Internet resources, which typically are HTTP and HTTPS.

·         UAG NAT64/DNS64 – If you need your force tunneling DirectAccess clients to access Internet using protocols other than those supported by a web proxy, and you configure them to use the UAG server’s NAT64/DNS64 service to route the connections through the UAG server to the Internet. You can put a web proxy or other web content filtering device in front of the UAG DirectAccess server if you want to control site access and perform malware filtering.

Steps for configuring the test lab

Note:

You must be logged on as a member of the Domain Admins group or as a member of the Administrators group on each computer to complete the tasks described in this guide. If you cannot complete a task while you are logged on with an account that is a member of the Administrators group, try performing the task while you are logged on with an account that is a member of the Domain Admins group.

·         Step 1: Complete the UAG SP1 RC DirectAccess Test Lab Guide. The UAG SP1 RC Test Lab Guide provides step by step instructions on how to create a working DirectAccess solution. The steps in this Test Lab Guide build on the steps in the UAG SP1 RC Test Lab Guide.

·         Step 2: Configure INET1 for Internet Access. INET1 is currently configured with a single network adapter that is connected to the Internet subnet. In this step you will add a second network adapter and connect that adapter to a “live” network that provides a path to the actual Internet. You will then install and configure RRAS on INET1 so that it can act as a NAT router for live Internet connections from UAG1 and TMG1.

·         Step 3: Install and Configure TMG1. When force tunneling is enabled for DirectAccess clients, you can provide DirectAccess clients access to the Internet through a web proxy server. In this step you will install the operating system on TMG1 and then install Forefront Threat Management Gateway 2010 on TMG1 so that TMG1 can provide web proxy services to CLIENT1.  

·         Step 4: Configure the Default Gateway on UAG1 and DC1.  UAG1 requires a path to the Internet. In this step you will configure UAG1 to use INET1 as its default gateway to provide that path. DC1 requires a path to the Internet to provide Internet name resolution. In this step you will configure DC1 to use TMG1 as its default gateway to provide that path.

·         Step 5: Configure UAG1 for Force Tunneling and Web Proxy Access to the Internet. In this step you will configure UAG1 to require DirectAccess client Force Tunneling and enable Internet access for DirectAccess clients through the TMG web proxy on TMG1.

·         Step 6: Update CLIENT1 and Test Proxy Access to the Internet. In this step you will update the Group Policy configuration on CLIENT1 and test its ability to reach the Internet through the web proxy on TMG1.

·         Step 7: Configure UAG1 for Force Tunneling and NAT64/DNS64 Internet Access. In this step you will configure UAG1 to require DirectAccess client Force Tunneling and enable Internet access for DirectAccess clients through UAG1 by taking advantage of the UAG NAT64/DNS64 feature.

·         Step 8: Update CLIENT1 and Test NAT64/DNS64 Access to the Internet.  In this step you will update the Group Policy configuration on CLIENT1 and test its ability to reach the Internet through the NAT64/DNS64 service on UAG1.

·         Step 9: Snapshot the Configuration – At the completion of the lab, snapshot the configuration so that you can later return to a working UAG DirectAccess Test Lab.

Note

You will notice that there are several steps that begin with an asterisk (*). The * indicates that the step requires that you move to a computer or virtual machine that is different from the computer or virtual machine you were at when you completed the previous step within the same section.

B.      Test Internet Access from CLIENT1 when Connected to Homenet. In this step you will test Internet access from CLIENT1 through the UAG NAT64/DNS64 services.

C.      View CLIENT1 Internet Activity in UAG1 TMG Log Files. In this step you will view the TMG log files on UAG1 to demonstrate that Internet connectivity is provided through UAG1.

D.     Update Group Policy on CLIENT1

1. While still located on the Homenet subnet, at the CLIENT1 computer or virtual machine, open an elevated command prompt. In the command prompt window, enter gpupdate /force and press ENTER. You will notice that User Policy will update correctly, but you will get an error that says machine policy cannot be updated. This is an expected error.
2. In the command prompt window, enter netsh namespace show policy and press ENTER. You should see an entry Settings for .  That section should have a line for DirectAccess (Proxy Settings): Bypass Proxy. This demonstrates that the new Group Policy settings were applied to CLIENT1. This entry tells CLIENT1 to connect to all sites over the DirectAccess tunnel using the UAG DirectAccess server.
3. Close the command prompt window.

E.      Test Internet Access from CLIENT1 when Connected to Homenet

1. Move CLIENT1 from the Corpnet subnet to the Homenet subnet. Open an elevated command prompt. In the command prompt window enter ipconfig /all.  You should see an entry for Tunnel adapter iphttpsinterface and an IPv6 address associated with that interface. CLIENT1 does not use Teredo because Force Tunneling requires the DirectAccess client to use IP-HTTPS.
2. In the command prompt window, enter netsh interface httpstunnel show interfaces and press ENTER. You should see that the Interface Status is IPHTTPS interface active.
3. In the command prompt window, enter ping app1 and press ENTER. You should see four responses from APP1.
4. In the command prompt window, enter net view \\APP1 and press ENTER. You should see a list of shares. This indicates that User1 was able to authenticate with the UAG DirectAccess server and user Kerberos authentication because connections to APP1 must be made through the intranet tunnel.
5. In the command prompt window, enter ping www.microsoft.com and press ENTER. You will see that the UAG DirectAccess server resolves the name for the client by generating a false IPv6 address, but the ping attempts fail because www.microsoft.com servers do not allow ping requests. In the command prompt window, enter ping www.facebook.com  and press ENTER. You should see four responses from an IPv6 address. Note that this is not the actual IPv6 address of the site; it is the IPv6 address generated by the NAT64 service on the UAG DirectAccess server. Close the command prompt window.
6. Open Internet Explorer. In the address bar, enter www.microsoft.com and press ENTER. You should see the home page on the www.microsoft.com web site.  Click several links on the page. Try to visit other web sites you are interested in. You should be able to connect to all web sites. Close Internet Explorer.

F.      View CLIENT1 Internet Activity in UAG TMG Log Files

1. *Move to the UAG1 computer or virtual machine. Click Start and click All Programs. Click Microsoft Forefront TMG and click Forefront TMG Management. In the User Account Control dialog box, click Yes.
2. In the Forefront TMG console, in the left pane, click the Logs & Reports node. In the right pane of the console, click the Tasks tab. Click the Edit Filter link.
3. In the Edit Filter dialog box, click the Log Time entry. In the Condition drop down list, select Last Hour. Click the Update button.
4. From the Filter by drop down list, select Rule. From the Condition drop down list, select Equals. In the Value drop down list, select DirectAccess Allow NATPT. Click Add To List. Click Start Query.
5. In the lower left side of the TMG console, wait until it says (Query is done). After the query is done, scroll through the list of entries. In the Protocol column you’ll see the protocols you used to access the Internet sites. In the Client IP column, you’ll see the IP-HTTPS IPv6 address assigned to the CLIENT1. You will some entries in the Protocol column for BranchCache – Retrieval Protocol. These entries actually represent the HTTP connections CLIENT1 made through the UAG1 NAT64/DNS64 services.

1. Close the Forefront TMG console

STEP 9: Snapshot the Configuration

1. On all physical computers or virtual machines in the test lab, close all windows and then perform a graceful shutdown.
2. If your lab is based on virtual machines, save a snapshot of each virtual machine and name the snapshots TLG UAG DirectAccess SP1RC FT. If your lab uses physical computers, create disk images to save the DirectAccess test lab configuration.
