User-defined Services

If you require a port or protocol that is not covered by any of the predefined services (see Predefined Services), you can create a custom service to be applied to a connection.

Navigate to Desktop > Services > User-defined Services to display the list of user-defined services that are currently defined in the system and displayed in the item list bar.

User-defined Services Overview

In the expanded view, the columns of the table display the Name of the service, indicate whether the service is used in a connection (green) or not (orange), and show the Ports and protocols used by the service. The buttons in the last column allow you to view and to adjust the settings of a user-defined service, create a service based on a copy of an existing user-defined service or delete a user-defined service from the system.

For more information, see Icons and buttons.

User-defined Services Settings

Under Desktop > Services > User-defined Services, you can add a new or edit an existing user-defined service.

The User-defined Services configuration dialog allows you to configure the following elements:

Input field	Description
Name	Enter a name for the user-defined service.
Ports / Protocols	To extend the user-defined service to apply to traffic to certain ports/port ranges and/or protocols, click Add to open the Edit Service panel. On this panel, you can define the ports and protocols to be used: The Source Port can optionally be restricted for the TCP or UDP protocol. If you select the Restrict Source Port option, you can specify individual ports or ranges for TCP or UDP in order to apply the service to traffic that is transmitted from a source port. Use the Source Port From and To input fields to enter values. The value can be any integer from `1` to `65535`. Geben Sie für TCP und UDP einzelne Ports oder Bereiche an, um den Dienst auf Verkehr anzuwenden, der von einem Quellport übertragen wird. Verwenden Sie die Eingabefelder Quell-Port von und To, um Werte einzugeben. Als Eingabewert ist jede ganze Zahl zwischen `1` und `65535` möglich. Source Port From and To form a port range. To enter an individual port, use the same value for both fields or leave To blank. For the protocols TCP or UDP, specify individual ports or ranges to extend the service to apply to traffic being transmitted to a certain destination port. Use the Destination Port From and To input fields to enter a value. The value can be any integer from `1` to `65535`. Destination Port From and To form a port range. To enter an individual port, use the same value for both fields or leave To blank. Specify a protocol to which the service is to be applied by selecting it from the list. Define any missing protocols under Protocols. The buttons at the bottom right of the editor panel allow you to confirm your changes (OK) and to discard your changes (Cancel). The Edit Service panel shuts automatically. The specified ports/port ranges and/or the protocol appear as a list entry. You can edit or delete individual entries in the list by clicking the corresponding button next to an entry. For more information, see Icons and buttons.

The specified ports/port ranges and/or the protocol appear as a list entry. You can edit or delete individual entries in the list by clicking the corresponding button next to an entry. For more information, see Icons and buttons.

The buttons at the bottom right of the editor panel depend on whether you add a new user-defined service or edit an existing one. For a newly configured user-defined service, click Create to add it to the list of available services or Cancel to discard your changes. To edit an existing user-defined service, click Save to store the reconfigured service or Reset to discard your changes. You can click Close to shut the editor panel as long as no changes have been made on it.

Click Activate in the toolbar at the top of the desktop to apply your configuration changes.

The user-defined services defined here are available for use in custom firewall rules (see Creating a firewall rule).
