Windows Server 2012 R2 Test Lab Guide: Demonstrate VPN Auto trigger

  • Artikkeli

 

Applies To: Windows Server 2012 R2

Windows® 8.1 allows a Microsoft or third party VPN clients to automatically connect to the corporate network when specified applications are launched.

If auto triggering is enabled for a VPN profile, a remote access connection is triggered whenever a specific application is accessed. If user credentials are cached within the VPN profile, the VPN connection will be automatically established without any user interaction.

In this Guide

This guide provides step-by-step instructions for configuring new Windows VPN capability in a test lab to demonstrate functionality and operation. You will set up and deploy Remote Access based on the Windows Server® 2012 R2 Base Configuration using four server computers and one client computer. The resulting test lab simulates an intranet and the Internet.

Important

The following instructions are for configuring a Remote Access test lab using the minimum number of computers. Individual computers are needed to separate the services provided on the network and to clearly show the desired functionality. This configuration is neither designed to reflect best practices nor does it reflect a desired or recommended configuration for a production network. The configuration, including IP addresses and all other configuration parameters, is designed only to work on a separate test lab network. Attempting to adapt this Remote Access test lab configuration to a pilot or production deployment can result in configuration or functionality issues.

Test Lab Overview

In this test lab, Remote Access is deployed with:

  • One computer running Windows Windows Server 2012 R2 named DC1 that is configured as an intranet domain controller, Domain Name System (DNS) server, and Dynamic Host Configuration Protocol (DHCP) server

  • One intranet member server running Windows Server 2012 R2 named EDGE1 that is configured as a Remote Access server

  • One intranet member server running Windows Server 2012 R2 named APP1 that is configured as a general application server and web server

  • One standalone server running Windows Server 2012 R2 named INET1 that is configured as an Internet DHCP server, DNS server, and web server

  • One non-domain-joined, Internet-connected client computer running Windows 8.1 named CLIENT2 that is configured as a Remote Access VPN client

The Remote Access test lab consists of two subnets that simulate the following:

  1. The Internet (131.107.0.0/24)

  2. An intranet named Corpnet (10.0.0.0/24) separated from the Internet by EDGE1

Automatic triggering of VPN connections is not supported on domain joined machines. Configuration of auto triggering properties on domain joined machines is possible through Windows PowerShell so that the profile can be exported to another computer. However, auto triggering will not work in a VPN profile if the client is domain joined. This modular test lab demonstrates Remote Access VPN auto trigger functionality using a non-domain-joined Windows 8.1 client. This test client computer is used to show connectivity to corporate resources via a simulated Internet (the Internet subnet).

Hardware and software requirements

The following are required components of the test lab:

  • The product disc or files for Windows Server 2012 R2

  • The product disc or files for Windows 8.1

  • Five computers or virtual machines that meet the minimum hardware requirements for Windows Server 2012 R2

Steps for Configuring the Remote Access VPN Auto-trigger Test Lab

There are four steps to follow when setting up a Remote Access VPN Auto-trigger test lab based on the Test Lab Guide: Base Configuration.

  1. Set up the Base Configuration test lab.

    The Remote Access simplified setup test lab requires the Test Lab Guide: Base Configuration with both Corpnet and Internet subnets, as its starting point.

  2. Configure EDGE1.

    EDGE1 is already a member server computer. For the Remote Access VPN auto-trigger test lab, EDGE1 must be configured as a Remote Access server with VPN access deployed

  3. Configure INET1.

    INET1 is already a Windows Windows Server 2012 R2 that is configured as an Internet DNS server, web server, and DHCP server. For the Remote Access VPN auto-trigger test lab, INET1 must be configured with a DNS record for the internetsite.corp.contoso.com Internet resource

  4. Configure CLIENT2.

    Add CLIENT2 as a standalone client computer running Windows Server 2012 R2. For this test lab, CLIENT2 will be used to test and demonstrate remote access VPN auto-trigger functionality and operation.

Note

You must be logged on as a member of the Domain Admins group or 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.
