Netgear D6200 Manual Do Utilizador

The WAN Setup screen lets you configure the WAN (Internet) port. 



Select ADVANCED > Setup > WAN Setup.

Configure the following settings:

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 or videoconferencing. Be careful when using this feature because it makes the 
firewall security less effective. For more information, see 

Respond to Ping on Internet Port. If you want the WiFi DSL modem router to 
respond to a ping from the Internet, select this check box. Use this feature only as a 
diagnostic tool because it allows your WiFi DSL 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 

48.
