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 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 of newsgroups.
1.Enter the Starting Port and Ending Port numbers. If the application uses a single port number, enter that number in both boxes.
2.If you know that the application uses either TCP or UDP, select the appropriate protocol. If you are not sure, select Both.
Configuring Service Blocking by IP Address Range
Under “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.
