DESCRIPTION

NAT Setup

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.
