Advanced Configuration
This chapter describes how to configure the advanced features of your DG824M Wireless ADSL
Modem Gateway.
Configuring Advanced Security
The DG824M Wireless ADSL Modem Gateway provides a variety of advanced features, such as:
• Setting up a Demilitarized Zone (DMZ) Server
• The flexibility of configuring your LAN TCP/IP settings
These features are discussed below.
Setting Up A Default DMZ Server
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The gateway is programmed to recognize some of
these applications and to work properly with them, but there are other applications that may not
function well. In some cases, one local PC can run the application properly if that PC’s IP address
is entered as the Default DMZ Server.
Note: For security, you should avoid using the Default DMZ Server feature. When a
computer is designated as the Default DMZ Server, it loses much of the protection of the
firewall, and is exposed to many exploits from the Internet. If compromised, the
computer can be used to attack your network.
