DMZ Settings
To access this feature, click on “DMZ” on the left side of the screen.
Demilitarized Zone (DMZ) is a feature that allows a computer to be
exposed to the Internet by “placing” it outside of the firewall. This feature
comes in handy when playing Internet games that don’t work well with a
firewall. Also, streaming video applications can benefit from bypassing the
NAT firewall security. To place a computer in the DMZ, enter the IP
address of the computer here. The Router supports one computer in the
DMZ. Please note that when a computer is not protected by the firewall it
is open to hacker attacks. Use this feature only when needed.
Virtual Server Settings
The Router can be
configured as a virtual
server. Your WAN interface
must use a fixed IP address
to utilize the virtual server
function. Using the virtual
server function will allow
clients accessing services
such as Web or FTP at
your local site via public
IP addresses to be
automatically redirected to
local servers configured with private IP addresses. In other words,
depending on the requested service (TCP/UDP port number), the Router
redirects the external service request to the appropriate server (located at
another internal IP address). For example, if you set Type/Public Port to
TCP/80 (HTTP or Web) and the Private IP/Port to 192.168.2.2, port 80,
then all HTTP request from clients will be transferred to 192.168.2.2.
Therefore, by just entering the IP Address provided by the ISP, Internet
users can access the service they need at the local address to which you
redirect them. Some of the more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23 and POP3: 110.
