Configure Firewall Settings

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, refer to
"Virtual Server" on page 33) to allow access to your computers or network devices from
the Internet.

Virtual Server

Advanced > Firewall > Virtual Server
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
to "DMZ" on page 33) 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
page 35.
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 on the Internet" on page

UDP).
ͫ Public Port: Enter the port number used to access the device from the Internet.
ͫ Private Port: Enter the port number required by your device. Refer to the connecting
device's documentation for reference to the network port(s) required.
The Public Port can be assigned a different port number than the Private
ÍNote:
Port (also known as port redirection), however it is recommended to use the
same port number for both settings. Please refer to the device documentation to
determine which ports and protocols are required. It is recommended to assign a
static IP address to the device or use DHCP reservation to ensure the IP address of
the device does not change.
ͫ Inbound Filter: Select the defined IP address range to allow access.
ͫ Schedule: Click New Schedule to select the pre-defined schedule to apply. The filter
will only be active during the time period defined in the pre-defined schedule.
