N750 Wireless Dual Band Gigabit ADSL Modem Router DGND4000
WAN Setup
The WAN Setup screen lets you configure a DMZ (demilitarized zone) server, change the
maximum transmit unit (MTU) size, and enable the wireless modem router to respond to a
ping on the WAN (Internet) port.
1.
Select ADVANCED > Setup > WAN Setup.
2.
The available settings and information in this screen are:
•
WAN Preference. Select your WAN preference: Auto-Detect, Must use DSL WAN, or
Must use Ethernet WAN.
•
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, Teardrop
Attack, UDP Flood, ARP Attack, Spoofing ICMP, Null Scan, and many others. This
feature should be disabled only in special circumstances.
•
Default DMZ Server. This feature is sometimes helpful when you are playing online
games and/or videoconferencing. Be careful when using this feature because it
makes the firewall security less effective. See the following section,
Server, for more details.
•
Respond to Ping on Internet Port. If you want the wireless modem router to
respond to a ping from the Internet, select this check box. Use this only as a
diagnostic tool because it allows your wireless modem router to be discovered. Do
not select this check box unless 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. For some
ISPs, you might need to reduce the MTU. This change is rarely required, and should
not be done unless you are sure that it is necessary for your ISP connection. See
Change the MTU Size
on page 50.
