NAT (Network Access Translation)
The NAT feature provides the basic firewall feature to avoid hacker attacks from
remote site. There are three more setting pages including virtual server, port trigger,
and DMZ to provide specified service for remote users.
Virtual Server
Virtual Server enables you to run a server on your local network that can be accessed
from the remote parties. You need to set up a rule to tell the device on which computer
the server is held. When port virtual server is enabled, your router (the device) routes
all the inbound traffic on a particular port to the chosen computer on your network.

Click Add to add a rule of virtual server.

Port Triggering
The feature is similar to the virtual server, but provides a more secure way to provide
your device. It opens up the port hole temporary and allows CPE in LAN to establish a
connection with remote parties. Those ports are open only if a specified request from
a PC in LAN is received, and then the device allows the remote parties to access to
establish a connection with that PC in LAN.

DMZ
A DMZ (DeMilitarized Zone) host is a computer on your network that can be accessed
from the Internet. The de-militarised zone (DMZ) is for forwarding IP packets from the
remote parties that are not fixed to any of the applications configured in the virtual
server. These packets are forwarded to a designated DMZ host device. A DMZ is
often used to host Web servers, FTP servers etc that need to be accessible from the
Internet
