Subnets are confi gured in the main window of the Confi guration program, in the
???Applications??? area.
Creating a Trunk
When a new trunk gets created, the Confi guration program activates the Create New
Trunk Wizard (see Figure 8.15). This enables the administrator quick auto-complete of
the initial trunk setup, external Web site, authentication, application customization, and
URL inspection rules. A trunk can be made under the HTTP and the HTTPS services.

TIP
It will be useful to go through the IAG Service Policy Manager a. It is possible to
preconfi gure a list of IP addresses and port numbers, which you can use to assign
IP addresses and port numbers to the services when creating and editing trunks.

Basic Trunk
Basic trunks enable the establishment of a one-to-one connection, where one IP
address routes to a single generic Web application. This type of trunk will be used in
a scenario where the organization has a single Web application, which will be of benefi t
to be published to a Web portal.
