Default Services Overview

The Default Services view displays the Dell SonicWALL Security Appliance default services in the Services table and Service Groups table. The Service Groups table displays clusters of multiple default services as a single service object. You cannot delete or edit these predefined services. The Services table displays the following attributes of the services and service groups:

•	Name—The name of the service.

•	Protocol—The protocol of the service.

•	Port Start—The starting port number for the service.

•	Port End—The ending port number for the service.

•	Class—Indicates whether the entry is a Default (system) or Custom (user) service.

•	Comments—Displays for the service group the Reference By applicable network address objects, firewall service objects, and network access rules, as well as Groups (Member of) service or application group type.

•	Configure—Displays the unavailable Edit and Delete icons (default services cannot be edited or deleted, you will need to add a new service for the Edit and Delete icons to become available).

Services that apply to common applications are grouped as Default Service Groups. These groups cannot be changed or deleted. Clicking on the + to the left of the Default Service Groups entry, displays all the individual Default Services included in the group. For example, the DNS (Name Service) entry has two services labelled DNS (Name Service) TCP for port 53 and DNS (Name Service) UDP for port 53. These multiple entries with the same name are grouped together, and are treated as a single service. Default Services Groups cannot be edited or deleted.
