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 

) 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 broadband ADSL2+ modem already holds a list 
of many service port numbers, you are not limited to these choices.
