General Information on Services

Services are a collection of rules or a set of instructions to permit or deny a particular type of traffic through the Firewall, for example, a telnet session. Services figure prominently when defining connections. They specify the type of traffic that can or cannot take place between network objects. The IBM Firewall comes preloaded with a default set of services. You can add to services by using the rule templates to create new rules.

The figure below illustrates how services are composed of rule templates and how they can become part of a connection configuration.
