Netgear JWNR2000v2 - Wireless-N 300 Router 사용자 설명서

WAN Setup

The WAN Setup screen lets you disable port scan and DoS protection, configure a DMZ 
(demilitarized zone) server, enable the router to respond to a ping on the WAN (Internet) port, 
enable IGMP proxying, and change the Maximum Transmit Unit (MTU) size. 

Select 

Advanced > WAN Setup to display the following screen:

Disable Port Scan and DOS Protection. The firewall protects your LAN against port scans 

and denial of service (DOS) attacks. This protection should be disabled only in special 
circumstances.

Default DMZ Server. The default demilitarized zone (DMZ) server feature is helpful when 

you use online games and video conferencing applications that are incompatible with NAT. 
The router is programmed to recognize some of these applications and to work correctly with 
them, but there are other applications that might not function well. In some cases, one local 
computer can run the application correctly if that computer’s IP address is entered as the 
default DMZ server.

Respond to Ping on Internet. If you want the router to respond to a ping from the Internet, 

select this check box. This should be used only as a diagnostic tool, because it allows your 
router to be discovered. Do not select this check box unless you have a specific reason to do 
so.

Disable IGMP Proxying. IGPM (Internet Group Management Protocol) proxying is disabled 

by default. When IGPM Proxying is enabled, your router acts as an IGMP-based host, 
forwarding IGMP messages and responding to IGMP queries.

MTU Size (in bytes). The normal Maximum Transmit Unit (MTU) value for most Ethernet 

networks is 1500 bytes, or 1492 bytes for PPPoE connections. For some ISPs you might 
need to reduce the MTU. But this is rarely required, and should not be done unless you are 
sure it is necessary for your ISP connection.
