•
Only This Computer
. Allow access from a single IP address on the Internet. Enter
the IP address to be allowed access.
•
IP Address Range
. Allow access from a range of IP addresses on the Internet. Enter
a beginning IP address and an ending IP address to define the allowed range.
•

Specify the port number for accessing the web management interface.
Normal web browser access uses the standard HTTP service port 80. For greater
security, enter a custom port number for the remote web management interface. Choose
a number from 1024 to 65535, but do not use the number of any common service port.
The default is 8080, which is a common alternate for HTTP.

View 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 the WAN settings:
1.
Launch a web browser from a computer or wireless device that is connected to the
network.
2.
Type
or
.
A login screen displays.
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 screen displays.
4.
Select ADVANCED > Setup > WAN Setup.
The following settings display:
•
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
109.
•
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

•
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.
•
VPN passthrough
. These features will be implemented in a firmware upgrade.

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 in the Port
Forwarding/Port Triggering screen. 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
or
.
