•SPI and Anti-DoS (Denial-of-Service) firewall protection
(Default: Disabled) – The Intrusion Detection Feature limits
access for incoming traffic at the WAN port. When the SPI
(Stateful Packet Inspection) feature is turned on, all incoming
packets will be blocked except for those types marked with a
check in the Stateful Packet Inspection section.
•Discard Ping from WAN (Default: Disabled) – Prevents the
router from responding to any PING request on the WAN port.

DMZ (Demilitarized Zone)
If you have a client PC that cannot run an Internet application
properly from behind the firewall, then you can open the client up
to unrestricted two-way Internet access. Enter the IP address of
a DMZ host to this screen. Adding a client to the DMZ may
expose your local network to a variety of security risks, so only
use this option as a last resort.

DDNS (Dynamic DNS) Settings
Domain Name – A series of alphanumeric strings separated by
periods that maps to the address of a the Router network
connection and identifies the owner of the address.
Dynamic DNS provides users on the Internet with a method to tie
their domain name to the router or server. DDNS allows your
domain name to follow your IP address automatically by having
your DNS records changed when your IP address changes.
The section also has a “Server Configuration” section that
automatically opens the port options checked in the Virtual
Server section. Simply enter in the IP Address of your server,
such as a web server, and then click on the port option “HTTP
Port 80” so users can access your server from the WAN
connection (Internet).

This DNS feature is powered by TZO.com. With a DDNS
connection you can host your own web site, E-mail server, FTP
site, and more at your own location even if you have a dynamic
IP address. (Default: Disable)
UPnP (Universal Plug and Play) Setting
Enable UPnP by checking ON in the screen above. UPnP allows

TROUBLESHOOTING
The information outlined in this section describes some useful
steps for getting your computer and the Router online.
A. Verify your connection to the Router
If you are unable to access the Router’s web-based
administration pages then you may not be properly connected or
configured. The screen shots in this section were taken on a
Windows 2000 machine, but the same steps will apply to
Windows 95/98/Me/XP.
To determine your TCP/IP configuration status please follow the
steps below:
1. Click Start then choose Run.
2. Type cmd or command to open a DOS prompt.
3. In the DOS window, type ipconfig and verify the information
that is displayed.
4. If your computer is set up for DHCP, then your TCP/IP
configuration should be similar to the information displayed:
•IP Address: 192.168.2.X (x is number between 100 and
199 by default.)
•Subnet: 255.255.255.0
•Gateway: 192.168.2.1
69
Troubleshooting
If you have an IP address that starts with 169.254.XXX.XXX then
see the next section.
If you have another IP address configured, then see section C.
B. I am getting an IP Address that starts with
169.254.XXX.XXX
If you are getting this IP Address, then you need to check that
you are properly connected to the Router.
Confirm that you have a good link light on the Router for the port
this computer is connected to. If not, please try another cable.
If you have a good link light, please open up a DOS window as
described in the previous section and type ipconfig/renew.
If you are still unable to get an IP Address from the Router,
reinstall your network adapter. Please refer to your adapter
manual for information on how to do this.
C. I have another IP Address displayed
If you have another IP address listed then the PC may not be
configured for a DHCP connection. Please refer to “Configuring
Client TCP/IP” on page 12 for information.
Once you have confirmed your computer is configured for DHCP,
then please follow the steps below.
1. Open a DOS window as described above.
70
2. Type ipconfig/release.
3. Then type ipconfig/renew.
Troubleshooting
D. The 10/100 LED does not light after a connection is made.
1. Check that the host computer and the Router are both
powered on.
2. Be sure the network cable is connected to both devices.
3. Verify that Category 5 cable is used if you are operating at
100 Mbps, and that the length of any cable does not exceed
100 m (328 ft).
4. Check the network card connections.
5. The 10BASE-T/100BASE-TX port, network card, or cable
may be defective.
