Multiple DMZ
The router supports one hardware DMZ port, multiple software DMZ ports, plus one default
DMZ port.
The hardware DMZ is implemented through the hardware: the router has a separate hardware
Ethernet port, to which multiple devices with public IP addresses assigned by the ISP can be
connected. Incoming data for these devices from the Internet will be sent by the router to the
hardware Ethernet port directly. No configuration would be required.
Both the default and multiple DMZ ports are implemented through software.
When the router receives incoming data from the Internet, it will search through an internal
address translation table to perform address translation function. If a match cannot be found, the
data will be forwarded to a special device for processing.
An additional feature is to allow devices with WAN IP addresses to be used by the Internet users
to access private devices in your local LAN. In this case, you need to configure the mapping
between the WAN IP address and the private IP address.
To add the default DMZ, you need to select “Default DMZ” and enter the local DMZ IP
address, followed by pressing the ADD button.
To add a device for multiple DMZ, first select “Multiple DMZ”, add a name, a public WAN
IP address, and the local DMZ IP address on the LAN, followed by pressing the ADD button.
You can delete a DMZ entry by selecting the corresponding entry and press the DELETE
SELECTED button.
