View or Change the WAN Settings
You can view the 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. Laun
ch a web browser from a WiFi-enabled computer or mobile device that is
connected to the network.
2. Ty
pe http://routerlogin.net or http://192.168.0.1.
A login window opens.
3. Enter
the modem router user name and password.
The user name is ad
min. The default password is password. The user name and
password are case-sensitive.
The BASIC Home page displays.
4. Select ADVANCED > Setup > WAN Setup
.
5. V
iew or change the following settings:
• Disa
ble IPv4 Firewall Protection.
• Disable Port Scan and DoS Protection. DoS prote
ction 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 fe
ature 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 53.
• Respond to Ping on Internet Port. This fea
ture allows your modem router to be
discovered. Use this feature only as a diagnostic tool or if there is a specific reason.
