consecutive IP addresses, or all computers on your network. Enter the starting port and ending
port numbers. If the application uses a single port number, enter that number in both fields.
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.
