Applications & Gaming > Port Range

Triggering

The Port Range Triggering screen allows the router to

watch outgoing data for specific port numbers. The IP

address of the computer that sends the matching data is

remembered by the router, so that when the requested

data returns through the router, the data is pulled back

to the proper computer by way of IP address and port

mapping rules.

Port Range Triggering

For each entry, complete the following:

Application Name Enter the name of the application.

Each name can have up to 12 characters.

Triggered Range Enter the starting and ending port

numbers of the outgoing traffic. Check the Internet

application’s documentation for more information.

Forwarded Range Enter the starting and ending port

numbers of the incoming traffic. Check the Internet

application’s documentation for more information.

Enabled Select Enabled to activate port triggering.

Applications and Gaming > DMZ

The DMZ (DeMilitarized Zone) feature allows one

network device to be exposed to the Internet for use

of a special-purpose service, such as online gaming or

videoconferencing. The router forwards all the ports at

the same time to the DMZ device (also called host). The

Port Range Forwarding feature is more secure because

it only opens the ports you want to have opened, while

DMZ hosting opens all the ports of one device, exposing

the device to the Internet.

Applications and Gaming > DMZ

DMZ

Any device whose port is being forwarded should have

its DHCP client function disabled and have a new static IP

address assigned to it because its IP address may change

when using the DHCP function.

Enabled/Disabled To disable DMZ hosting, keep the

default, Disabled. To expose one device, select Enabled.

Then configure the options below.

Source IP Address To allow any IP address from the

Internet to access the DMZ device, select Any IP Address.

To specify an IP address or range of IP addresses from the

Internet to access the DMZ device, select and complete

the IP address range fields.

Destination To specify the DMZ device by IP address,

select IP Address and enter its IP address. If you need to

assign a static IP address to the device, then go to “DHCP

Reservation” on page 7.

To specify the DMZ device by MAC address, select MAC

Address and enter its MAC address. To look up its MAC

address, click DHCP Client Table.

DHCP Client Table

The DHCP Client Table screen appears. It lists computers

and other devices that have IP addresses assigned

by the router. The list can be sorted by Client Name,

Interface, IP Address, and MAC Address.
