5.10 User-defined Services
The tables that appear on the Add access control rule (see figure 5.4 ) and Add local
server (see figure 5.7 ) screens are pre-configured to include most of the services
that users may wish to block or activate. Sometimes, however, the need arises
to add a new service. GlobeSurfer 3G provides the
User-defined services table
(see figure 5.22 ) for this purpose. This table can be accessed from the Add access
control rule and Add local server screens. When a service is added in one place
it automatically appears in the other. In this way, user-defined services never
need to be entered twice.
• To add a new service:
1. Click the New user-defined service link at the top of either the Add
access control rule screen or the Add local server screen. The Edit service
screen will appear (see figure 5.22 ).

2. Enter a name for the service.
3. Enter a description for the service.
4. Click the New server ports link. The Edit service server ports screen will
appear (see figure 5.23 ).

5. Choose the source and/or destination port types and enter the port
number or range for this service to use appropriately. This informa-
tion is usually available as part of the documentation that accompa-
nies the program that needs access to or from the Internet.
