Creating a User-Defined Service Type
You will need to enter the protocol, starting point, and ending point for the service type.
• Protocol. If you know that the application uses either TCP or UDP, select the appropriate
protocol. If you are not sure, select TCP/UDP.
• Starting Point and Ending Point. Enter the starting port and ending port numbers. If the
application uses a single port number, enter that number in both fields.
To define a service, you must determine which port number or range of numbers the
application uses. The service 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. This information can usually be determined by contacting the
publisher of the application or from user groups or news groups.
• Filter Services For. You can block the specified service for a single computer, a range of
computers (having consecutive IP addresses), or all computers on your network.
