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 Virtual Server (also called port forwarding, see
“
Virtual Server” on page 35) to allow access to your computers or network devices from
the Internet.
1. Log into your router management page (see “
Access your router management page”
on page 17).
2. Click on the Advanced tab.
3. Click on the Firewall section and click on DMZ.
4. Select Enable in the DMZ Settings section.
5. Enter the IP address you assigned to the computer or network device to expose to the
Internet. Click Apply to save settings.
Virtual Server
Advanced > Firewall > Virtual Server Rules
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 IP camera
(TRENDnet IP cameras default to HTTP TCP port 80 for remote access web requests) on
your network to be able to view it over the Internet. To open several ports please refer
to “
Gaming” section on page 37.
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
(outlined in
Identify Your Network section page 50).
1. Log into your router management page (see “
Access your router management page”
on page 17).
2. Click on the Advanced tab.
