Logs are sent automatically according to the schedule that you set. If the log fills before the specified time, it is

sent. After the log is sent, it is cleared from the router memory. If the router cannot email the log and the log

buffer fills, the router overwrites the log.

Network Settings

The router comes ready for WiFi, Ethernet, and USB connections.You can customize the router’s network settings.

NETGEAR recommends that you install the router and connect it to the Internet before you change its network settings.

View or Change WAN Settings

You can view or configure 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 router to respond to a ping to its WAN

(Internet) port.

To view or change the WAN settings:

1.

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

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

Set Up a Default DMZ Server

on

page 50.

•

Respond to Ping on Internet Port

. This feature allows your router to be discovered. Use this feature only

as a diagnostic tool or for a specific reason.

Disable IGMP Proxying

. IGMP proxying allows a computer on the local area network (LAN) to receive the

multicast traffic it is interested in from the Internet. If you do not need this feature, you can select this check

box to disable it.

•

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 ISP connection. See

Change the MTU Size

on page 32.

•

NAT Filtering

. Network Address Translation (NAT) determines how the router processes inbound traffic.

Secured NAT protects computers on the LAN from attacks from the Internet but might prevent some Internet

games, point-to-point applications, or multimedia applications from working. Open NAT provides a much

less secured firewall but allows almost all Internet applications to work.

Set Up a Default DMZ Server

The default DMZ server feature is helpful when you are using some online games and videoconferencing applications

that are incompatible with Network Address Translation (NAT). The router is programmed to recognize some of

these applications and to work correctly with them, but other applications might not function well. In some cases,

one local computer can run the application correctly if the IP address for that computer is entered as the default

DMZ server.

WARNING:

DMZ servers pose a security risk. A computer designated as the default DMZ server

loses much of the protection of the firewall and is exposed to exploits from the

Internet. If compromised, the DMZ server computer can be used to attack other

computers on your network.

The router usually detects and discards incoming traffic from the Internet that is not a response to one of your local

computers or a service that you configured on the Port Forwarding/Port Triggering page. Instead of discarding this

traffic, you can specify that the router forwards the traffic to one computer on your network. This computer is called

the default DMZ server.

To set up a default DMZ server:

1.

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

2.

Type

A login window opens.
