SonicOS Enhanced supports an expanded IP protocol support to allow users to create services and 
access rules based on these protocols. See “Supported Protocols” on page 146 for a complete listing 
of support 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.
