Port Trigger Panel
Some applications require multiple ports open for communication, many of which may be initiated
by a computer on the WAN. Examples of this include video conferencing, VoIP (Internet
telephony), and Internet gaming.
With port triggering, the device monitors outgoing data on specific port numbers (trigger ports).
The device keeps track of the IP address of the computer that sends data on these trigger ports,
so that when incoming data on the forward ports arrives, the device sends the incoming data to
the same computer.
Before you can use or configure port triggering, you must enable it, as explained in “Enabling Port
Triggering” below.
From the
Port Trigger
panel of the
Router
tab of the
Advanced Settings
window, you can:
●
Enable port triggering for specified protocols and ports. (See “Enabling Port Triggering for
Specified Protocols and Ports” below.)
●
Remove protocols and ports from the port triggering list. (See “Removing Ports From the Port
Triggering List” on page 104.)
Enabling Port Triggering
Before you can use or configure Port Triggering, you must enable it.
1.
Log in to the home page.
2.
Click
Advanced Settings > Router > Basic
.
3.
Next to
Port Triggering
, select
Enable
.
Enabling Port Triggering for Specified Protocols and Ports
1.
Make sure you've enabled port triggering. (See “Enabling Port Triggering” [above].)
2.
Click
Advanced Settings > Router > Port Trigger
.
3.
In the last row of the table, in the first
Protocol
list, click the protocol(s) used by the application
for outgoing traffic (to the Internet, sent through the trigger ports).
4.
In the
Trigger Ports
field, enter the port number(s) used to determine that the application is in
use. (That is, specify the port number or range of port numbers that the application uses for
outgoing traffic. Check the user documentation for the application.)
To specify a range of port numbers, separate the start and end port number with a hyphen.
5.
In the second
Protocol
list, click the protocol(s) used by the application for incoming traffic
(from the Internet).
6.
In the
Forward Ports
field, enter the ports to forward to the computer that triggered the rule.
(That is, specify the port number or range of port numbers that the application uses for
incoming traffic. Check the user documentation for the application.)
7.
To specify a range of port numbers, separate the start and end port number with a hyphen.
8.
Make sure
Enable
is selected.

Removing Ports From the Port Triggering List
1.
Make sure you’ve enabled port triggering. (See “Enabling Port Triggering” on page 103.)
2.
Click
Advanced Settings > Router > Port Trigger
.
3.
To keep the entry in the list (in case you want to re-enable this entry later on), clear the

Cancel
) appears.

DMZ Panel
DMZ stands for “demilitarized zone.” You can select one computer to receive all unsolicited incoming
connections.
The IP address of the DMZ is the default recipient of incoming packets (from the Internet) that are not
handled by port forwarding rules, port triggering rules, or NAT’d connections:
1.
If port forwarding, port triggering, or both are enabled, incoming traffic is routed according to the
port forwarding rules, port triggering rules, or NAT’d connections.
2.
If incoming traffic was not routed as a result of the above:
±
If DMZ is enabled, then incoming traffic is routed to the computer that uses the IP address
specified by the DMZ settings.
±
If DMZ is not enabled, the incoming traffic is blocked.
Enabling DMZ
Before you can use or configure DMZ, you must enable it.
1.
Log in to the home page.
2.
Click
Advanced Settings > Router > Basic
.
3.
Next to
DMZ
, select
Enable
.
4.
Click
Save
.
Note:
Putting a computer in the DMZ opens all the ports of that computer, and exposes that computer to
various security risks. Use this option only as a last resort — if possible, use other options instead (for
example, port forwarding or port triggering).

Configuring DMZ
1.
Make sure you’ve enabled DMZ. (See “Enabling DMZ” on page 104.)
2.
Click
Advanced Settings > Router > DMZ
.
3.
Specify the computer that you want exposed to the Internet: in the
Destination IP Address
field, enter the IP address of the computer. (If you don’t know how to find the IP address, see
“Finding the IP Address” on page 122.)
4.
In the
Source IP Address
section, specify what incoming traffic (not handled by port
forwarding, port triggering, or NAT) to forward to this computer.
To forward all incoming traffic, click
Any
.
— or —
To forward incoming traffic from certain IP addresses:
±
Click
Restriction
.
±
In the two additional fields that are displayed, enter the start and end IP addresses of a
range.
5.
Using the DHCP Static IP Assignment List, assign an IP address based on the MAC address
of the computer that is in the DMZ. (See “Assigning an IP Address Based on a MAC Address”
on page 100.)
— or —
On the computer that is in the DMZ, disable DHCP, and manually assign the IP address,
gateway, and DNS server.
Resetting the Software to Default Settings
You’ll need to reset the software to default settings if:
●
You’ve forgotten the administrator password.
●
You’ve changed the DHCP settings such that the device is inoperable (for example, there’s no
communication with the device).
You have two options to initiate the reset:
●
Through the software. (See “Resetting the Software to Default Settings (Through the Browser
Interface)” on page 107.)
●
Through the reset button on the device. (See the following section.)
WARNING:
If you reset the software to default settings:
• You must go through the device setup (page 20), as if you've just purchased the device.
• Any changes you’ve made to the settings are lost.
Your 3G and 4G account information is not affected; after reset, the device remains
provisioned for service.
