Single Service

The Single Service option lets you add new network services and control the filtering activites applied when a service is used in a rule. Control the filtering activites by specifying the packet filtering engine you want to use and the various discriminators and parameters applicable to that filtering engine.

Use the fields and controls in the Service dialog to enter the configuration information for the service.

• Name Specifies the name of the service object.
• Description (Optional) Provides a brief description about the service object.
• Screen Specifies which Screen recognizes the service object.
• Add Filter Adds a row to the filter table, which provides a way for you to define additional filters for the service.
• Add Port Provides a way for you to specify additional ports used by the forward filter. This button becomes active when the Port field in the filter table has the focus.

Use the Filter table to define the filtering activities.

• Filter Identifies the state engine.
• Port Identifies the port, program number, or type used by the forward filter.
• Broadcast Determines whether the rules where the service is used allows communication to broadcast and multicast addresses. Note: If you want the service to work for non-broadcast addresses, enter separate table entries for broadcast and non-broadcast filtering.
• Parameters Identifies the parameters for the state engine.
• Reverse Determines whether the filter is applied to packets originating from the host in the To address of a rule and going to the From address of a rule.
