NETGEAR N300 Wireless Router JWNR2000v2 User Manual

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.
