Configuring Custom Services

Firewall > Services

Services are anything a server provides to other computers. A service can be as simple as the computer asking a server for the correct time (NTP) and the server returns a response. Other types of services provide access to different types of data. Web servers (HTTP) respond to requests from clients (browser software) for access to files and data. Services are used by the SonicWALL security appliance to configure network access rules for allowing or denying traffic to the network.

User Defined (Custom) Services

If protocol is not listed in the Predefined Services table, you can add it to the User Defined (Custom) Services table.
