SonicOS supports an expanded IP protocol support to allow users to create services and access rules based on these protocols. See Supported Protocols for a list of pre-defined protocols. And refer to Adding Custom IP Type Services to add specific IP protocols required for your network.
Services are used by the Dell SonicWALL Security Appliance to configure network access rules for allowing or denying traffic to the network. The Dell 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.
