Netgear AC1750 Owner's Manual

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. 



Launch a web browser from a computer or wireless device that is connected to the 

network.

A login window opens.

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 page displays.

Select ADVANCED > Setup > WAN Setup.

View or change the following settings:

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 

Respond to Ping on Internet Port. This feature allows your 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 Internet connection. See
