WiFi Cable Modem Router Model C3000v2 and C3700v2
Set Up a Default DMZ Server
The default DMZ server feature is helpful when you are using some online games and
videoconferencing applications that are incompatible with Network Address Translation
(NAT). The modem router is programmed to recognize some of these applications and to
work correctly with them, but other applications might not function well. In some cases, one
local computer can run the application correctly if the IP address for that computer is entered
as the default DMZ server.
WARNING:
DMZ servers pose a security risk. A computer designated as the
default DMZ server loses much of the protection of the firewall and
is exposed to exploits from the Internet. If compromised, the DMZ
server computer can be used to attack other computers on your
network.
The modem router usually detects and discards incoming traffic from the Internet that is not a
response to one of your local computers or a service that you configured on the Port
Forwarding/Port Triggering page. Instead of discarding this traffic, the modem router can
forward the traffic to one computer on your network. This computer is called the default DMZ
server.
To set up a default DMZ server:
1.
Launch a web browser from a WiFi-enabled computer or mobile device that is
connected to the network.
2.
Type
http://routerlogin.net

3.
Enter the modem router user name and password.
The user name is

password are case-sensitive.
