Network Address 

Translation

Network Address Translation (NAT) allows the translation of an Internet protocol 

address used within one network (for example a private IP address used in a local 

network) to a different IP address known within another network (for example a 

public IP address used on the Internet). 
Select the check box to enable NAT.

Default Server

In addition to the servers for specified services, NAT supports a default server. A 

default server receives packets from ports that are not specified in the Application 

screen. 
If you do not assign a Default Server IP address, the ZyXEL Device discards all 

packets received for ports that are not specified in the Application screen or 

remote management.
