Open a device on your network to the Internet

This router can provide access to devices on your local area network to the Internet
using the Virtual Server, Special Application, method (DMZ NOT recommended).

DMZ

Advanced > Firewall > DMZ
You may want to expose a specific computer or device on your network to the Internet
to allow anyone to access it. Your router includes the DMZ (Demilitarized Zone) feature
that makes all the ports and services available on the WAN/Internet side of the router
and forwards them to a single IP address (computer or network device) on your
network. The DMZ feature is an easy way of allowing access from the Internet however,
it is a very insecure technology and will open local area network to greater threats from
Internet attacks.
It is strongly recommended to use Port Forwarding to allow access to your computers or
network devices from the Internet.

1. Make sure to configure your computer or network device to use a static IP address or
you can use the DHCP reservation feature (see "Set up DHCP reservation" on page

2. Log into your router management page (see "Access your router management page"
on page 23).
3. Click on Advanced, click on DMZ.

Note: If using ADSL WAN with multiple PVCs, click the DMZ Mode drop-down list to
select Multi Mode which will allow you which PVC to assign the DMZ Host.

Port Forwarding

Virtual Server (also called port forwarding) allows you to define specific ports (used or
required by a specific application) and forward them to a single IP address (a computer
or device) on your network. Using this feature is more secure compared to using DMZ
(see "DMZ" on page 35) in which DMZ forwards all ports instead of only specific ports
used by an application. An example would be forwarding a port to an network/IP
camera (typically on TRENDnet IP cameras use HTTP TCP port 80 for remote access web
requests) on your network for to allow remote access to it.
Since most ISPs constantly change your home IP address, to be able to access the Virtual
Server port(s) from the Internet it is recommended to setup Dynamic DNS service (See
DynDNS section).
1. Log into your router management page (see "Access your router management page"
on page 23).
2. Click on Advanced, click on Port Forwarding and click Add.
