To define a new service, you need to determine first which port number or range of numbers
is used by the application. You can usually determine this information by contacting the
publisher of the application, user groups, or newsgroups. When you have the port number
information, you can enter it on the Services screen.
 To add a customized service:
1. Select Network Security > Services. The Services screen displays. The Custom
Services table shows the user-defined services. (The following figure shows some
examples.)
Figure 85.
2. In the Add Customer Service section of the screen, enter the settings as explained in the
following table:
