QoS. Select a service from the drop-down list box.

File Transfer Program enables fast transfer of files, including large files that
may not be possible by e-mail. FTP uses port number 21.

Electronic mail consists of messages sent through a computer network to
specific groups or individuals. Here are some default ports for e-mail:
POP3 - port 110

• WWW

information, based on Hyper Text Transfer Protocol (HTTP) - a client/server
protocol for the World Wide Web. The Web is not synonymous with the
Internet; rather, it is just one service on the Internet. Other services on the
Internet include Internet Relay Chat and Newsgroups. The Web is accessed
through use of a browser.
• User-Defined
User-defined services are user specific services configured using known ports
and applications.
