Configuring a User-Defined Service
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 RFC1700, “Assigned Numbers.” Service
numbers for other applications are typically 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 newsgroups, or by searching.
Enter the starting port and ending port numbers. If the application uses a single port number,
enter that number in both fields.
If you know that the application uses either TCP or UDP, select the appropriate protocol. If
you are not sure, select
Both
