Chapter 4: Software Configuration
DMZ Host IP Address: Enter the specified IP Address for DMZ host on the LAN side.
Note: For security reasons, you should avoid using the default DMZ server feature. When a
computer is designated as the default DMZ server, it loses much of the protection of the firewall,
and is exposed to many exploits from the Internet. If compromised, the computer can be used
to attack your network .
Virtual Server
The Virtual Server is the servers behind NAT (on the LAN), for example, Web server or FTP server,
that you can make visible to the outside world even though NAT makes your whole inside
network appear as a single machine to the outside world. Please assign a static IP address to the
destination computer before you use this feature.
Start & End port number: Enter the specific start and end port number you want to forward. If
it is one port only, you can enter the end port number the same as start port number. For
example, you want to set the FTP virtual server, you can set the start and end port number to 21.
