Network Service Groups

Network services can be organized into service groups, so that a single rule can apply to multiple network services. The table below lists the predefined service groups in SunScreen and the services that each group includes. Note that some services are members of more than one group, and other services are not included in any service group.

The common group compiles to list every service within the group in a specific order based on state-engine precedence. When a packet comes through, it tries to match each state engine in order of its precedence.

Note -

See "* Service" for information about the * service, which has some of the characteristics of a service group.
