An Administration Console must be installed before you can install the Access Gateway Service. See Installing the Access Manager Administration Console.
An Identity Server must be installed and configured before installing the Access Gateway Service. See, Section 4.0, Installing the NetIQ Identity Server.
The Access Gateway Service must be installed on a separate machine.
Verify that the machine meets the minimum requirements. See Section 2.6, Access Gateway Requirements.
Verify that the time on the machine is synchronized with the time on the Administration Console. If the times differ, the Access Gateway Service does not import into the Administration Console.
If a firewall separates the machine and the Administration Console, ensure that the required ports are opened. See When a Firewall Separates the Administration Console from a Component
in the NetIQ Access Manager 3.2 SP3 Setup Guide.
Because the Access Gateway Service is running as a service, you need to be aware that the default ports (80 and 443) that the Access Gateway Service uses might conflict with the ports of other services running on the machine. If there is a conflict, you need to decide which ports each service can use.
(Windows Server 2008) If the Web server (IIS) has been installed by default during the Windows Server 2008 install, the Access Gateway Service installation program detects its presence from the registry and issues a shutdown command. Even if you have never activated the Web server and if even it is not running, the shutdown command is issued. Because the Access Gateway Service cannot be installed while the IIS server is running, the installation program needs to ensure that it is not running.
The Access Gateway Service clustering is supported for devices that are on the same operating system.
