View WAN Settings
You can view or configure wide area network (WAN) settings for the Internet port. You can set 
up a DMZ (demilitarized zone) server, change the maximum transmit unit (MTU) size, and 
enable the modem router to respond to a ping to its WAN (Internet) port. 
To view the WAN settings:
1.  Launch an Internet browser from a computer or wireless device that is co\
nnected to the 
network.
2.  T
ype  http://www.routerlogin.net  or http://www.routerlogin.com .
A login screen displays.
3.  Enter the user name and password.
The user name is  admin. 
 The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4.  Select 
ADVANCED > Setup > WAN Setup.
The following settings display: • Disable IPv4 Firewall Protection. NETGEAR recommends that you leave this check 
box empty so that the firewall protects your modem router.
• Disable Port Scan and DoS Protection. DoS protection protects your LAN against 
denial of service attacks such as Syn flood, Smurf 

Attack, Ping of Death, and many 
others. Select this check box only in special circumstances. 
• Default DMZ Server . This 
 feature is disabled by default. It is sometimes helpful when 
you are playing online games or videoconferencing, but it makes the fire\
wall security 
less effective. See Set Up a Default DMZ Server on page  58.
• Respond to Ping on Internet Port. 
 This feature allows your modem router to be 
discovered. Use this feature only as a diagnostic tool or if you have a \
specific reason. 
• MTU Size (in bytes). 
 The normal MTU (maximum transmit unit) value for most 
Ethernet networks is 1500 bytes, or 1492 bytes for PPPoE connections. Ch\
ange the

MTU only if you are sure that it is necessary for your ISP connection. See Change the 
MTU Size on page 24.
•Disable SIP ALG. Some VoIP applications do not work well with the SIP ALG. 
Selecting this check box to turn off the SIP ALG might help your VoIP devices to 
create or accept a call through the modem router.

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 have configured in the Port 
Forwarding/Port Triggering screen. Instead of discarding this traffic, you can have the modem 
router 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 an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4. Select ADVANCED > Setup > WAN Setup.

Change the Modem Router’s Device Name
The modem router’s device name is C7000. This device name displays in file manager when 
you browse your network.
To change the modem router’s device name:
1. Launch an Internet browser from a computer or wireless device that is connected to the 
network.
2. Type http://www.routerlogin.net or http://www.routerlogin.com.
A login screen displays.
3. Enter the user name and password.
The user name is admin. The default password is password. The user name and 
password are case-sensitive.
The BASIC Home screen displays.
4. Select ADVANCED > Setup > LAN Setup.
5. In the Device Name field, type a new name.
6. Click the Apply button.
Your change is saved.
Change the LAN TCP/IP Settings
The modem router is preconfigured to use private IP addresses on the LAN side and to act 
as a DHCP server. The modem router’s default LAN IP configuration is as follows:
•LAN IP address. 192.168.0.1
•Subnet mask. 255.255.255.0
These addresses are part of the designated private address range for use in private networks 
and are suitable for most applications. If your network requires a different IP addressing 
scheme, you can change these settings
You might want to change these settings if you need a specific IP subnet that one or more 
devices on the network uses, or if you have competing subnets with the same IP scheme.
