Wireless-G ADSL Gateway with 2 Phone Ports
DMZ
The DMZ screen allows one local user to be exposed to the Internet for use of a special-purpose service such as
Internet gaming and videoconferencing through DMZ Hosting. DMZ hosting forwards all the ports for one
computer at the same time, which differs from Port Range Forwarding, which can only forward a maximum of 10
ranges of ports.
DMZ Hosting. This feature allows one local user to be exposed to the Internet for use of a special-purpose
service such as Internet gaming and videoconferencing. To use this feature, select Enabled. To disable DMZ ,
select Disabled.
DMZ Host IP Address. To expose one computer, enter the computer’s IP address. To get the IP address of a
computer, refer to Appendix D: Finding the MAC Address and IP Address for Your Ethernet Adapter.

QOS
Quality of Service (QoS) ensures better service to high-priority types of network traffic, which may involve demanding, real-
time applications, such as Internet phone calls or videoconferencing.
QoS
Enable/Disable. To utilize QoS on the Gateway, select Enable. Otherwise, keep the default, Disable.
Application-based QoS
Application-based QoS manages information as it is transmitted and received. Depending on the settings of the QoS screen,
this feature will assign information a high or low priority for the five preset applications and three additional applications that
you specify.
High priority/Medium priority/Low priority. For each application, select High priority (traffic on this queue shares 60% of
the total bandwidth), Medium priority (traffic on this queue shares 18% of the total bandwidth), or Low priority (traffic on
this queue shares 1% of the total bandwidth).
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.
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.
