Network Settings
The router comes ready for WiFi, Ethernet, and USB connections.You can customize the router’s network settings. We
recommend 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 WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the 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

The following settings display:

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
Set Up a Default DMZ Server
on
page 68.
•
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 41.
•
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 WiFi device that is connected to the network.
2.
Enter
.
A login window opens.
3.
Enter the router user name and password.
The user name is
admin
.The default password is
password
.The user name and password are case-sensitive.

Set Up Ethernet Port Aggregation
Ethernet aggregation lets you combine two Gigabit Ethernet ports to improve the aggregated file transfer speed.
Note that Ethernet port aggregation is also referred to as link aggregation, teaming port, and port trunking. If a device
supports Ethernet aggregation, you can use the Ethernet aggregate ports 1 and 2 to cable the device that supports
Ethernet port aggregation to the router.
To get the fastest performance with port aggregation, for wired connections use Ethernet
port 3 for the first computer, and use Ethernet port 4, 5 or 6 for the second computer, which
allows for speeds up to 2 Gbps with port aggregation. The maximum speed between port 4,
5 and 6 is limited to 1 Gbps.
Note
NETGEAR ReadyNAS equipment with two Ethernet ports such as model RN100/200/300/500/700 desktop series
and the ReadyNAS RN2000/3000/4000 rack-mount series support Ethernet aggregation.

To set up Ethernet port aggregation:
1.
If you are connecting a switch, make sure that the switch supports 802.3ad LACP.
You must configure the switch before you connect the Ethernet cables to the router.
WARNING:
To avoid causing broadcast looping, which can shut down your network, do not
connect an unmanaged switch to Ethernet aggregate port 1 and port 2 on the router.
2.
Use Ethernet cables to connect a device that supports Ethernet port aggregation, such as a NAS or network
switch, to Ethernet port 1 and port 2 on the router.
3.
Set up Ethernet port aggregation on the device that is connected to Ethernet port 1 and port 2 on the router.
For information about how to set up Ethernet port aggregation on your device, see the documentation that came
with your device.
For information about viewing the status of the Ethernet port aggregation, see
View Ethernet Port Aggregation
