Create Service Groups
A service group can contain a collection of predefined and customized services. (TCP and
UDP customized services can be included in a service group.) You use a service group as a
firewall object to which you apply a firewall rule, that is, you select the service group from the
Service drop-down list on a screen on which you add or edit a firewall rule.
One advantage of a service group is that you can create a single firewall object with multiple
noncontiguous ports (for example ports 3000, 4000, and 5000) and apply the object in a
single firewall rule. For example, if there are 10 web servers, each of which requires the
same three port-forwarding rules, you can create a service group for the port-forwarding
rules, an IP group for the web servers (see Create IP Groups on page 167), and then create
only one firewall rule.
To create a service group:
1. Select Network Security > Services > Service Group. The Service Group screen
displays. (The following figure shows two groups in the Custom Service Group table as
an example.)
