This allows almost any application to be used on the "DMZ PC".
The "DMZ PC" will receive all "Unknown" connections and data.

If the DMZ feature is enabled, you must enter IP address of the PC to be used
as the "DMZ PC".
The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
URL Filter
If you want to limit access to certain sites on the Internet, you can use this feature.
The URL filter will check each Web site access. If the address, or part of the ad-
dress, is included in the block site list, access will be denied.
On the
Advanced Internet
screen, select the desired setting:
Disable
- disable this feature.
Block Always
- allow blocking all of the time, independent of the
Schedule
page.
Block By Schedule
- block according to the settings on the
Schedule
page.
Click the
Configure URL Filter
button to open the URL Filter screen, allowing you
to create or modify the filter strings which determine which sites will be blocked.
The
URL Filter
screen is displayed when the
Configure URL Filter
button on the
Advanced Internet
screen is clicked.

Dynamic DNS (Domain Name Server)
This free service is very useful when combined with the
Virtual Server
feature. It
allows Internet users to connect to your Virtual Servers using a URL, rather than an
IP Address.
This also solves the problem of having a dynamic IP address. With a dynamic IP
address, your IP address may change whenever you connect, which makes it
difficult to connect to you.
DDNS Services work as follows:
1.
You must register for the service at one of the listed DDNS Service providers.
2.
After registration, use the Service provider's normal procedure to obtain your
desired Domain name.
3.
Enter your DDNS data on the Wireless Router's DDNS screen, and enable the
DDNS feature.
4.
The Wireless Router will then automatically ensure that your current IP Address
is recorded at the DDNS service provider's Domain Name Server.
5.
From the Internet, users will be able to connect to your Virtual Servers (or DMZ
PC) using your Domain name, as shown on this screen.
Dynamic DNS Screen
Select
Advanced
on the main menu, then
Dynamic DNS
, to see a screen like the
following:

Use this to enable or disable the DDNS feature as required.
Service Provider
Select the desired DDNS Service provider.
Web Site
Click this button to open a new window and connect to the Web
site of the selected DDNS service provider.

DDNS Data
Host Name
Enter the domain name allocated to you by the DDNS Service.
If you have more than one name, enter the name you wish to
use.
User Name
Enter your Username for the DDNS Service. (TZO.com uses
your E-mail address.)
Password
Enter your current password for the DDNS Service. (TZO.com
calls this a key.)
DDNS Status
This message is returned by the DDNS Server.
Normally, this message should be "Update successful"
If the message indicates some problem, you need to
connect to the DDNS Service provider and correct this
problem.
