Reference Manual for the Model DM602 ADSL Modem
5-10 Advanced Configuration of the Modem
The Default DMZ Server feature is helpful when using some online games and videoconferencing
applications that are incompatible with NAT. The modem 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.
The Security menu, shown in Figure 5-9, allows the configuration of a Default DMZ Server.
Figure 5-9. DMZ menu.
To assign a computer or server to be a Default DMZ server:
1. Check the check box to enable the DMZ feature
2. Type the IP address for that server.
3. Click Apply.
Device Mode
The modem includes a limited feature router to make the process of configuring your connection
easier and more secure. You can change the operation of the modem from Modem Device Mode to
Router Device Mode.
Note: For security, you should avoid using the DMZ Server feature. When a computer
is designated as the Default DMZ Server, it loses much of the protection of the modem,
and is exposed to many exploits from the Internet.
Note: If you need to delete the IP address of the DMZ server, you must enter 0.0.0.0 as
the address, and then click the Apply button.
