Multiple DMZ 

The router supports multiple software DMZ ports, and they 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 can be found, the 
data will be forwarded to the corresponding device in your local LAN, otherwise the data will be 
dropped or forwarded to the default DMZ if it is configured. 

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 mnemonic 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.
