Configure Services
Services are functions performed by server computers at the request of client computers. For
example, Web servers serve Web pages, time servers serve time and date information, and
game hosts serve data about other players' moves. When a computer on the Internet sends a
request for service to a server computer, the requested service is identified by a service or
port number. This number appears as the destination port number in the transmitted IP
packets. For example, a packet that is sent with destination port number 80 is an HTTP (Web
server) request.
The service numbers for many common protocols are defined by the Internet Engineering
Task Force (IETF at http://www.ietf.org/) 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. Although the wireless modem router already holds a list of
many service port numbers, you are not limited to these choices.
