With port triggering, we define two kinds of ports: Trigger Port and Target Port. Trigger

port is the service request with a specific destination port number sent from a LAN side

host. Target Port is the port this specific application requires a LAN host to listen to. Thus,

the server returns responses to these ports.

For example:

1.

John requests a file from the Real Audio server (port 7070).

Port 7070 is a “trigger”

port and causes the device to record John’s computer IP address. The DVW3201B

associates John's computer IP address with the “target” port range of 6970-7170.

2. The Real Audio server responds to a port number ranging between 6970-7170.

3. The DVW3201B forwards the traffic to John’s computer IP address.

4. Only John can connect to the Real Audio server until the connection is closed or times

out.

Steps

To set up port triggering:

1.

Click the

Gateway

link from the top of the screen.

2. Click

Using the Advanced Gateway Settings Pass Through Option

The

Pass Through

option allows you to configure a pass through table. Devices in the

pass through table are treated as bridge devices that store and forward data between

LAN interconnections.

Label

Description

Trigger Range

Defines the trigger port or a range of ports that trigger the

router to record the IP address of the LAN computer that sent

the traffic to a server on the WAN.

Start Port

Defines a port number or the starting port number in a range

of port numbers.

End Port

Defines a port number or the ending port number in a range of

port numbers.

Target Range

Defines a target range port or a range of ports a server on the

WAN uses when it responds to service requests. The router

forwards the traffic with this port (or range of ports) to the

client computer on the LAN that requested the service.

Start Port

Defines a port number or the starting port number in a range

of port numbers.

End Port

Defines a port number or the ending port number in a range of

port numbers.

Protocol

Defines the protocol type for this rule, UDP, TCP, or Both.

Enable

Activates this rule when checked.

Using the Advanced Gateway Settings DMZ Host Option

The

DMZ Host

option allows you to configure a host IP address to be exposed (visible) to

the WAN (public Internet). This may be used when applications do not work with port

triggers or other networking strategies.

5.13.1

Using DMZ Host Best Practices

The following instructions are best practices when adding a device into a DMZ.

1.

Connect a PC to an Ethernet port on the DVW3201B. Make sure both devices are

powered on and functioning.

2. Connect a Home Gateway (or other device you wish to be in the DMZ) to an Ethernet

port on the DVW3201B.

3. Log in to the DVW3201B Web user interface.

Label

Description

Index

Defines the index number of the pass through rule.

MAC Address

Defines the input host’s MAC address.

Clear

Deletes this rule when checked and the Apply button is

clicked.

4. Go to

Tools

>>

Client

List

. Your PC and other devices are listed. Note the MAC

address and IP address of the Home Gateway, VoIP Phone, or other device to put in

the DMZ. For more information, refer to

Using the Client List Option on page 83

.

5. Go to

Gateway

>>

Static

Lease

. Enter the MAC address and IP address of a Home

Gateway (or other device you wish to be in the DMZ).

6. Click

Apply

. For more information, refer to

Using the DHCP Static Lease Option on

page 39

. A static lease ensures that the device is assigned the same IP address so it

is always available on the network, especially if devices are powered on/off or

disconnected and reconnected.

7. Go to

Gateway

>

Advanced

>

DMZ

Host

. Enter the IP address you just configured in

the Static Lease section.

8. Test the device to ensure Internet access is available and the device is functional (for

example, connect to the Internet from a PC connected to the Home Gateway, or make

calls from a VoIP phone).

Steps

To expose an IP address to the WAN:

1.

Click the

Gateway

link from the top of the screen.

2. Click

DMZ Host

from the left side of the screen. The

DMZ Host

fields are explained

following this screen example.

The following example shows the DMZ Host set up for a dual Xbox

configuration.
