Services

Shows a list of all default and custom services.

Services are definitions of certain types of network traffic and combine information about a protocol such as TCP, ICMP or UDP as well as protocol-related options such as port numbers. You can use services to determine the types of traffic allowed or denied by the firewall.

Certain well-known traffic types have been predefined in services. These predefined services are defaults, and cannot be updated or deleted. If you require service definitions that are different from the predefined services, you can add them as custom services.

The page also provides option to add a new service, update the parameters of the existing service, or delete a service.
Note
  • Service used by security policies cannot be deleted.
  • Default services can neither be updated nor deleted.
