View or Change the 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 cable 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 mobile device that is connected to the
cable modem router network.
2. Enter http://routerlogin.net or http://192.168.0.1.
A login window opens.
3. Enter the cable modem router admin user name and password.
The user name is admin. The password is the one that you specified the first time
that you logged in. The user name and password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Setup > WAN Setup.
The WAN Setup page displays.
5. View or change the following settings:
• Disable IPv4 Firewall Protection. We recommend that you leave this check box
cleared so that the firewall protects your cable 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 firewall
security less effective. See Set Up a Default DMZ Server on page 55.
• Respond to Ping on Internet Port. This feature allows your cable modem router
to be discovered. Use this feature only as a diagnostic tool or for 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 MTU only if you are sure that it is necessary for your ISP connection. See .
• 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 cable modem router.
