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.
Note
To open ISA Server Management, click Start, point to
All Programs, point to Microsoft ISA Server, and then
click ISA Server Management.
Important
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.
