Chapter 5: Configuring the Dual-Band Wireless A+G Broadband Router
The Applications and Gaming Tab - Port Range Forwarding
Dual-Band Wireless A+G Broadband Router
The Applications and Gaming Tab - Port Range Forwarding
The Port Range Forwarding screen allows you to set up public services on your network, such as web servers, ftp
servers, e-mail servers, or other specialized Internet applications. (Specialized Internet applications are any
applications that use Internet access to perform functions such as videoconferencing or online gaming. Some
Internet applications may not require any forwarding.)
Before using forwarding, you should assign static IP addresses to the designated PCs.
Port Range Forwarding
To forward a port, enter the information on each line for the criteria required. Descriptions of each criteria are
described here.
Application Name. Each drop-down menu offers a choice of ten preset applications (select None if you do not
want to use any of the preset applications). Select up to five preset applications. For custom applications, enter
the name of your application in one of the available fields.
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.
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 protocol that has no directory or password
capability.
Finger. A UNIX command widely used on the Internet to find out information 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.
