User's Manual

The Preset Applications are among the most widely used Internet applications
that may require forwarding. They include the following:
• FTP (File Transfer Protocol) A protocol used to transfer files over a TCP/IP
network (Internet, UNIX, etc.). For example, after developing the HTML
pages for a website on a local machine, they are typically uploaded to the
web server using FTP. FTP includes functions to log onto the network, list
directories, and copy files. It can also convert between the ASCII and
EBCDIC character codes. FTP operations can be performed by typing com-
mands at a command prompt or via an FTP utility running under a graphical
interface such as Windows. FTP transfers can also be initiated from within a
web browser by entering the URL preceded by ftp://.
• Telnet A terminal emulation protocol commonly used on Internet and
TCP/IP-based networks. It allows a user at a terminal or computer to log onto
a remote device and run a program.
• SMTP (Simple Mail Transfer Protocol) The standard e-mail protocol on the
Internet. It is a TCP/IP protocol that defines the message format and the
message transfer agent (MTA), which stores and forwards the mail.
• DNS (Domain Name System) The way that Internet domain names are
located and translated into IP addresses. A domain name is a meaningful and
easy-to-remember “handle” for an Internet address.
• TFTP (Trivial File Transfer Protocol) A version of the TCP/IP FTP proto-
col that has no directory or password capability.
• Finger A UNIX command widely used on the Internet to find out informa-
tion about a particular user, such as a telephone number, whether the user is
currently logged on, and the last time the user was logged on. The person
being “fingered” must have placed his or her profile on the system in order
for the information to be available. Fingering requires entering the full
user@domain address.
• HTTP (HyperText Transport Protocol) The communications protocol used
to connect to servers on the World Wide Web. Its primary function is to
establish a connection with a web server and transmit HTML pages to the
client web browser.

3. On the same line, select the protocol TCP or UDP, or select both protocols.
4. Enter the IP address of the server that you want the Internet users to be
able to access. To find the IP address, go to Appendix D: Finding the MAC
Address and IP Address for Your Ethernet Adapter.
5. Check the Enable box to enable the services you have defined. Port Range
Forwarding will not function if the Enable button is left unchecked. This is
disabled (unchecked) by default.
6. Configure as many entries as needed—the Router supports up to 10 ranges
of ports. Click the Apply button when you are done.
UPnP Forwarding
Clicking the UPnP Forwarding button on the Port Range Forwarding tab will
display the UPnP Forwarding tab. The UPnP Forwarding tab, shown in Figure
5-17, displays preset application settings as well as options for customization
of port services for other applications.
This table is similar to
the Port Forwarding
table, but the items on
this table will automat-
ically synchronize with
other UPnP devices
and operating systems,
such as Windows XP.
