Port forwarding allows you to define the local servers to which the incoming services will be
forwarded. To change your NBG334S's port forwarding settings, click Network > NAT >
Application. The screen appears as shown.
If you do not assign a Default Server IP address in the NAT > General
screen, the NBG334S discards all packets received for ports that are not
specified in this screen or remote management.

DESCRIPTION
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.
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 NBG334S discards all
packets received for ports that are not specified in the Application screen or
remote management.
Click Apply to save your changes back to the NBG334S.
