After you configure the intra-array addresses for an array, you can enable and configure NLB for the other networks connected to the array. When you configure NLB for a network, you must specify one virtual IP address for the network. The dedicated IP address and the virtual IP address must belong to the same subnet and have the same subnet mask. When configuring and deploying NLB-enabled networks, follow these guidelines:

Do not use a layer-2 switch to connect the array members. The reason is that NLB uses a virtual physical address for the virtual IP address. None of the ISA Server network adapters registers that physical address on the switch, so incoming packets are flooded to all ports on the switch. Instead, connect the network adapters to a hub and uplink that hub to the network switch. When NLB is enabled on all the networks in the array, you must add a network adapter that is dedicated for intra-array traffic. Place this network adapter on a separate network subnet. In this way, all outgoing traffic to other array members will pass only through this network adapter and not through load-balanced networks. When the Configuration Storage server is installed on an array member, the IP address that the array members use to access the Configuration Storage server

Implementing ISA Server 2004, Enterprise Edition
should be set to the intra-array address of the Configuration Storage server. Otherwise, the other array members may lose connectivity to the Configuration Storage server. To enable NLB on the ISA Server array, complete the following procedure: 1. In the ISA Server Management Console, expand Arrays, and then expand the array that you are configuring. 2. Expand Configuration and click Networks. 3. On the Tasks tab, click Enable Network Load Balancing Integration. 4. On the Welcome page, click Next. 5. On the Select Load Balanced Networks page, shown in Figure 12-22, select the network for which you want to enable NLB.

6. Click Set Virtual IP, and on the Set Virtual IP Address dialog box, type the virtual IP address and mask. Click OK. 7. Repeat steps 5 and 6 for the other networks on the array that you want to loadbalance. 8. Click Next, and then click Finish. 9. Click Apply to apply the changes. When you enable NLB, the firewall services on all array members need to be restarted.

Enabling CARP Support
You can also enable CARP on the ISA Server arrays. When you enable CARP, the cache drives on all the servers in the array are treated as a single logical cache drive. In this way, cached objects can be efficiently distributed among the member servers. ISA Server, Enterprise Edition, changes some of the options for configuring Web Proxy client and Firewall client connections. When deploying Web Proxy or Firewall clients with ISA Server, Standard Edition, you configure the clients to use the IP address or name of the ISA Server computer when connecting to remote resources. However, when deploying Web Proxy or Firewall clients with ISA Server, Enterprise Edition, the clients must connect to the array rather than the individual servers. To enable this, configure the ISA Server clients to use the array DNS name to connect to the array. When you create an array, the array is assigned a DNS name. You can modify the array DNS name after deployment. For the ISA Server clients to connect to the array DNS name, the clients must be able to resolve the name using DNS. This means that you must add the array DNS name to the DNS zone files used by the ISA Server clients. If the array contains more than one server, you should configure a DNS host record using the dedicated IP address for each array member. If you have CARP enabled for the array, the Web Proxy clients connect to the array using the array DNS name to download the CARP script. The clients use the script to determine which array member to connect to when accessing Web content.
Note The default gateway for SecureNAT clients should be configured to use the shared virtual IP address for the array if NLB is enabled, and the IP address of one of the array members if NLB is not enabled.
To enable CARP, you need to enable caching on at least one member server and then enable CARP for the array network. Complete the following procedure: 1. In the ISA Server Management Console, expand Arrays, and then expand the array that you are configuring. 2. Expand Configuration, and then click Cache. 3. Select one of the computers in the array, and click Define Cache Drives (Enable Caching). 4. In the Cache Drives dialog box, configure a maximum cache size and click Set. Then click OK. Apply the changes and accept the option to restart the services. 5. Enable caching on all the servers in the array.
