The Firewall>Services page allows you to create services and access rules based on IP protocols.
Services are used by the SonicWALL security appliance to configure network access rules for allowing or denying traffic to the network. The SonicWALL security appliance includes Default Services. Default Services are predefined services that are not editable. And you can also create Custom Services to configure firewall services to meet your specific business requirements.
Selecting All Services from View Style displays both Custom Services and Default Services.
The Default Services view displays the SonicWALL default services in the Services table and Service Groups table that 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 that are currently defined:
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 labeled 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.
All custom services you create are listed in the Custom Services table. You can create a group of services by creating a Custom Service Group for easy policy enforcement.
If a protocol is not listed in the Firewall>Default Services page, you can add it to the Custom Services table. All custom services you create are listed in the Custom Services table. You can group custom services by creating a Custom Services Group for easy policy enforcement. If a protocol is not listed in the Default Services table, you can add it to the Custom Services table by clicking Add.
Click the Enable Logging checkbox to disable or enable the logging of the service activities.
Click the Notepad icon under Configure to edit the service in the Edit Service window, which includes the same configuration settings as the Add Service window.
Click the Trash can icon to delete an individual custom service. You can delete all custom services by clicking the Delete button.
You can add custom services and then create groups of services, including default services, to apply the same policies to them. For example, you can allow SMTP and POP3 traffic only during certain hours or days of the week by adding the two services as a Custom Service Group.
To create a Custom Service Group:
Clicking+ on the left of a Custom Service Group name, expands the display to show all the individual Custom Services, Default Services, and Custom Services Groups included in the Custom Service Group entry.
Click the Notepad icon under Configure to edit the custom service group in the Edit Service Group window, which includes the same configuration settings as the Add Service Group window.
Click the Trash can icon to delete the individual custom service group entry. You can delete all custom service groups by clicking the Delete button.
