Instant Broadband™ Series

If you need to forward all ports to one PC, see the “DMZ” section.

To add a server using Port Range Forwarding:

1.Enter the name of the application in the appropriate Customized Applications field.

2.Next to the name of the application, enter the number or range of the exter- nal port(s) used by the server or Internet application in the Ext. Port column. Check with the Internet application software documentation for more infor- mation.

3.On the same line, select the protocol UDP or TCP, 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 F: 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

The UPnP Forwarding screen, shown in Figure 9-18, displays preset application settings as well as options for customization of port services for other applications.

The Preset Applications are among the most widely used Internet applications. 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 commands 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://.

EtherFast® Cable/DSL Routers

•Telnet A terminal emulation protocol commonly used on

Internet and TCP/IP-based net- works. It allows a user at a terminal or computer to log onto a remote device and run a program.

•S M T P ( S i m p l e

Mail Transfer Protocol) The stan- dard e-mail protocol on the Internet. It is a TCP/IP protocol that defines the mes- sage 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.
