To upload new firmware:
1. Download and unzip the new software file from NETGEAR.
2. In the Firmware Upgrade menu, click the Browse button and browse to the location of the
binary (.BIN) upgrade file
3. Click Upload.
Note: When uploading software to the DM602 modem, it is important not to interrupt the Web
browser by closing the window, clicking a link, or loading a new page. If the browser is
interrupted, it may corrupt the software. When the upload is complete, your modem will
automatically restart. The upgrade process will typically take about one minute.
In some cases, you may need to reconfigure the modem after upgrading.
DMZ
Incoming traffic from the Internet is normally discarded by the modem unless the traffic is a
response to one of your local computers or a service that you have configured in the Port
Forwarding menu. Instead of discarding this traffic, you can have it forwarded to one computer on
your network. This computer is called the Default DMZ Server.
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.
