 Chapter 11 Network Address Translation (NAT)

VMG1312-B10A User’s Guide

In addition to the servers for specified services, NAT supports a default server IP address. A default 
server receives packets from ports that are not specified in the NAT Port Forwarding Setup 
screen.

Network Setting > NAT > DMZ 

The following table describes the fields in this screen. 

Open Start Port The open port is a port (or a range of ports) that a server on the WAN uses when it sends 

out a particular service. The Device forwards the traffic with this port (or range of ports) to 
the client computer on the LAN that requested the service. 

Type a port number or the starting port number in a range of port numbers.

Open End Port 

Type a port number or the ending port number in a range of port numbers.

Open Protocol

Select the transport layer protocol from TCP, UDP, or TCP/UDP.
