N300 WiFi Cable Modem Router Model C3000
View or Change 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 or change the WAN settings:
1. Launch a web browser from a computer or wireless device that is connected to the
network.
2. Type http://routerlogin.net or http://192.168.0.1.
A login screen displays.
3. Enter the modem router 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.
5. View or change the following settings:
•Disable IPv4 Firewall Protection. The IPv4 firewall is enabled by default, which is
the setting that NETGEAR recommends. Some advanced users might want to disable
IPv4 firewall protection to examine the traffic coming in from the Internet.
•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 sometimes helpful when you are playing online
games or videoconferencing, but it makes the firewall security less effective. See Set

•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. Change the
