DESCRIPTION
NAT Setup
Enable 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 Setup
Server IP 
Address
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 NBG-419N 
discards all packets received for ports that are not specified in the 
Application screen or remote management.
