To configure virtual IP addresses for a network (Enterprise Edition)ISA Server 2006 Enterprise Edition only
In the console tree of ISA Server Management, click Networks:
- Expand Microsoft Internet Security and Acceleration Server 2006, expand Arrays, expand Array_Name, expand Configuration, and then click Networks.
In the details pane, click the Networks tab, and then select the applicable network.
On the Tasks tab, click Edit Selected Network.
On the NLB tab, in Virtual IP, type a virtual IP address to use for this network.
In Mask, type the 32-bit value for the subnet mask of the specified virtual IP address.
To open ISA Server Management, click Start, point to All Programs, point to Microsoft ISA Server, and then click ISA Server Management.
Network Load Balancing (NLB) cannot be configured for enterprise-level networks and for the following default array-level networks: Local Host, Quarantined VPN Clients, and VPN Clients.
When a virtual IP address is configured for a network, ISA Server adds the specified IP address to a network adapter on each server, and updates the routing table for that network adapter accordingly.
The combination of the virtual IP address and mask must yield the same subnet as the combination of the IP address and mask of the adapter in the network. The virtual IP address must belong to the network.
To add virtual IP addresses, on the NLB tab of the network properties, click Add VIP. Each of the addresses will be added to the matching network's network adapter with same subnet mask as that of the primary virtual IP address.
