Configuring Windows Server 2003 and IIS for DSR

The basic procedure below also applies to Windows XP and other versions of Windows.

1. Open Start > Control Panel and double-click Network Connections.
2. Select View > Tiles. If a Microsoft Loopback Adapter is already listed, proceed to the next step. Otherwise, to install the loopback interface as follows:

1. Open Start > Control Panel > Add Hardware, and then click Next.
2. Click Yes, I have already connected the hardware, and then click Next.
3. At the bottom of the list, click Add a new hardware device, and then click Next.
4. Click Install the hardware that I manually select from a list, and then click Next.
5. Click Network adapters, and then click Next.
6. In the Manufacturer box, click Microsoft.
7. In the Network Adapter box, click Microsoft Loopback Adapter, and then click Next.
8. Click Finish.

3. To configure the loopback interface for DSR:

1. In Network Connections, right click on the Microsoft Loopback Adapter and select Properties.
2. In the General tab, double-click on Internet Protocol (TCP/IP) in the scroll box.
3. Select Use the following IP address, and enter the IP address and Subnet mask for the Layer 4 cluster, as configured on FortiADC. Click OK.
4. Click OK to return to Network Connections.

4. To configure the IIS HTTP server for DSR:

Open Start > Administrative Tools > Internet Information Service (IIS) Manager.

1. In the left frame, expand the local computer and then Web Sites to display a list of the web sites running on the server.
2. Right-click on the web site you want to configure for DSR and select Properties.
3. On the Web Site tab, next to IP address, select the Advanced button.
4. Select the Add... button under the top list box.
5. Enter the IP address and the TCP port for the Layer 4 cluster, as configured on FortiADC. Click OK.
6. Click OK twice to return to the Internet Information Service (IIS) Manager.

You should now be able to send client requests to the cluster IP and port, and get responses directly from the IIS HTTP server running on Windows 2003. Remember that static routes on your servers may be necessary, depending on your network configuration.
