Common Problems and Solutions
ADSL2+ Gateway with VoIP
8. I can’t get the Internet game, server, or application to work.
If you are having difficulties getting any Internet game, server, or application to function properly, consider
exposing one PC to the Internet using DeMilitarized Zone (DMZ) hosting. This option is available when an
application requires too many ports or when you are not sure which port services to use. Make sure you
disable all the forwarding entries if you want to successfully use DMZ hosting, since forwarding has priority
over DMZ hosting. (In other words, data that enters the Gateway will be checked first by the forwarding
settings. If the port number that the data enters from does not have port forwarding, then the Gateway will
send the data to whichever PC or network device you set for DMZ hosting.) Follow these steps to set DMZ
hosting:
A. Access the Gateway’s web-based utility by going to
http://192.168.1.1
or the IP address of the Gateway.
Go to the
Router
>
Application
tab.
B. Disable or remove the entries you have entered for forwarding. Keep this information in case you want to
use it at a later time.
C. Select
yes
from the
Enable DMZ
drop-down menu.
D. Enter the Ethernet adapter’s IP address of the computer you want exposed to the Internet. This will bypass
the NAT security for that computer. Please refer to “Appendix B: Finding the MAC Address and IP Address
for Your Ethernet Adapter” for details on getting an IP address.
Once completed with the configuration, click the
Submit All Changes
button.
9. I am a PPPoE user, and I need to remove the proxy settings or the dial-up pop-up window.
If you have proxy settings, you need to disable these on your computer. Because the Gateway is the gateway
for the Internet connection, the computer does not need any proxy settings to gain access. Please follow
these directions to verify that you do not have any proxy settings and that the browser you use is set to
connect directly to the LAN.
For Microsoft Internet Explorer 5.0 or higher:
A. Click
Start
,
Settings
, and
Control Panel
. Double-click

.
B. Click the
Connections
tab.
C. Click the
LAN settings
button and remove anything that is checked.
D. Click the
OK
button to go back to the previous screen.
E. Click the option
Never dial a connection
. This will remove any dial-up pop-ups for PPPoE users.
For Netscape 4.7 or higher:
A. Start
Netscape Navigator
, and click
Edit
,
Preferences
,
Advanced
, and
Proxies
.
B. Make sure you have
Direct connection to the Internet
selected on this screen.
C. Close all the windows to finish.
