Network Load Balancing

Servicing Multiple Web Sites (Multihoming)

This scenario is a variation on the IIS Server Web farm scenario. The port-rule settings are the same; the scenarios differ in how you configure additional IP addresses for the cluster in the Advanced TCP/IP Settings dialog box.

For more information about port-rule settings, see "IIS Server (Web Farm)," earlier in this chapter.

Note that you enter additional virtual IP addresses in the Advanced TCP/IP Settings dialog box, not in the Network Load Balancing Properties dialog box.

Before performing the following procedure, be sure to enter the host's dedicated IP address and the cluster's primary IP address in the Network Load Balancing Properties dialog box and in the Advanced TCP/IP Settings dialog box, as described in Windows 2000 Advanced Server Help.

To host multiple Web sites with different IP addresses on a Network Load Balancing cluster

Click the Start menu, point to Settings, and then open Network and Dial-up Connections.
Click the Local Area Connection for which Network Load balancing is enabled, and then, in the Local Area Connection Status dialog box, click Properties.
In the Local Area Connection Properties dialog box, click Internet Protocol (TCP/IP), and then click Properties.
Click Advanced.
The list under IP Addresses should already contain the host's dedicated IP address and the cluster's primary IP address. This cluster IP address corresponds to the cluster's primary IP address that you entered in the Network Load Balancing Properties dialog box under Cluster parameters.
For each additional virtual IP address that your cluster needs in order to run a multihomed server, click Add, and then enter the cluster IP address, followed by the appropriate subnet mask.
