add any additional services or applications that do not already appear, select User
Defined. To define a service, first you must determine which port number or range of
numbers is used by the application. The service port numbers for many common
protocols are defined by the Internet Engineering Task Force (IETF) and published in

chosen from the range 1024 to 65535 by the authors of the application. You can often
determine port number information by contacting the publisher of the application, by
asking user groups or news groups, or by searching.
