DMZ
This feature, if enabled, allows one (1) computer on your LAN to be exposed to all users on
the Internet, allowing unrestricted 2-way communication between the "DMZ PC" and other
Internet users or Servers.
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 select the PC to be used as the "DMZ PC".
The DMZ feature can be Enabled and Disabled on the
Advanced Internet
screen.

To use this feature, you must define "filter strings". If the "filter string" appears in a

Access Log
. If Enabled, the "Destination"
field in the log will display the URL. Otherwise, it will display the IP Address.

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.
The Service works as follows:
1.
You must register for the service at http://www.dyndns.org (Registration is free). Your
password will be E-mailed to you.
2.
After registration, use the "Create New Host" option (at www.dyndns.org) to request your
desired Domain name.
3.
Enter your data from www.dyndns.org in the TW100-BRV304 's DDNS screen.
4.
The TW100-BRV304 will then automatically ensure that your current IP Address is
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
Internet
on the main menu, then
