Network sets are the grouping of defined networks on your ISA server. Rules can be applied against network sets to either include one or more networks or exclude one or more networks, depending on how you have chosen to configure the rule. This section focuses on the default network sets created with the installation of ISA Server and how you can create network sets as you continue to realize the capabilities of multinetworking.
When you wish to control a collection of networks, you can group them together into a network set. For example, if you have several different VPNs defined, and you wish to control all networks, you can create a network set. Several preconfigured network sets exist:
All Networks (And Local Host) Includes all possible networks, including the Local Host network defining the ISA server itself.
All Protected Networks Includes all networks except for the external network.
To create a network set, follow these steps:
In the console tree, expand the server name, expand Configuration, and click Networks.
In the details pane, click the Network Sets tab.
In the task pane, click the Tasks tab. Under Network Sets Tasks, click Create A New Network Set.
On the Welcome To The New Network Set Wizard page, type a new network set name, then click Next.
On the Network Selection page, select either Includes All Selected Networks or Includes All Networks Except The Selected Networks, then select the appropriate networks.
On the Completing The New Network Set Wizard page, review your settings, then click Finish.
Click Apply to save the changes, and then click OK to close the Apply Network Configuration dialog box.
