Block Services (Port Filtering)

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 the 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

1 2 ... 57 58 59 60 61 62 63 64 65 66 67 ... 81 82
