This tool will also allow you to MAP DHCP IP Addresses to 
certain MAC Addresses. This tool works well in conjunction 
with the Parental Control rules to provide maximum control.
  Website Blocking
The [Website Blocking] feature of the Barricade™ limits 
access to website domains (i.e. www.somesite.com) or by 
using keywords which will block any websites that have that 
keyword in the URL. This feature is an ideal way to protect 
your family members from questionable content on the Internet.

[Advanced Firewall Settings]
This section allows you to configure several advanced 
features for the Barricade™ Firewall.
The following features can be set on this page:
[Advanced Firewall Protection:] 
Enable/Disable SPI section of firewall.
[Discard Ping from WAN:] 
When this feature is enabled, any host on the WAN 
cannot ping this product. This helps avoid unnecessary 
attacks from the WAN side because your connection is 
invisible. It is recommended that you enable this option 
for security.
[VPN Pass-through:] 
Enable this option if you are using a PPTP, L2TP 
or IPSec VPN connection.  
						

							Advanced Setup
41
[Email Settings:] 
Configure this option if you want the Barricade™ to 
email when hackers attempt to attack your network to 
a specific email address. You will need to configure your 
email address, username and password, as well as a 
SMTP server to send the mail through.
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 
PC up to unrestricted two-way Internet access. Enter the LAN 
IP address of a DMZ host and click [Enable]. 
Note: 
Adding a client to the DMZ (Demilitarized Zone) may 
expose your local network to a variety of security risks.  
Only use this option as a last resort.
DDNS (Dynamic DNS)
The Barricade™ has an integrated Dynamic DNS feature 
that provides 
users on the Internet a method to tie their domain 
name(s) to computers 
or servers. 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).
UPnP
The Barricade™ supports UPnP (Universal Plug and Play), 
a networking architecture that provides compatibility amongst 
networking equipment. This feature allows an UPnP based 
operating system, like Windows XP to automatically 
communicate with the Barricade™ and open the required 
services when needed.

TROUBLESHOOTING
The information outlined in this section describes some useful 
steps for getting your computer and Barricade™ router online.
Verify you are connected to the 
Barricade™ Router
If you are unable to access the Barricade™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 setup 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)
[Subnet]: 255.255.255.0
[Gateway]: 192.168.2.1 
						

							Troubleshooting
48
If you have an IP address that starts with 169.254.XXX.XXX 
then see section “I am getting an IP Address that starts with 
169.254.XXX.XXX”.
If you have another IP address configured, see section “I have 
another IP Address displayed”.
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 Barricade™ Router.
Confirm that you have a good link light on the Barricade™s 
port to which this computer is connected.  If not, please try 
another cable.
If you have a good link light, please open up a DOS window 
as described
 in section “Verify you are connected to the 
Barricade™ Router” and type ipconfig/renew. 
						

							Troubleshooting
49
If you are still unable to get an IP Address from the Barricade™, 
reinstall your network adapter. Please refer to your adapter 
manual for instructions.
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 
your Computer 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.
2.Type ipconfig/release.
