5. Enter information in the forwarding fields as shown in the screen shot below. Field

descriptions follow.

Label

Description

Local IP Address

Defines the IP address of the local LAN device to which the

forwarding rule applies. For example, an Xbox or PC.

Local Start Port

Defines the starting port number listened to by the server host

located in your LAN.

Local End Port

Defines the ending port number listened to by the server host

located in your LAN.

External IP Address

Designates another router on the network through which to

forward data.

External Start Port

Defines the port number to start the range of ports to publish

to the Internet.

External End Port

Defines the port number to end the range of ports published to

Internet.

Note:

Be very careful with ranges. Ports within a range are not

usable by other applications that may require them. It is

common and safer to enter the same port number as the start

and end of the range.

Protocol

Selects the protocol type. Options are UDP, TCP, or BOTH.

Description

Names the forwarding rule.

Enabled

Disables (Off) or enables (On) the forwarding rule.

Cancel

Stops creating the forwarding rule and returns you to the

previous Forwarding screen.

Apply

Saves changes.

Setting Up Forwarding for an Xbox Example

Following is an example of how you would set up a single Xbox running Modern

Warfare

2. Since multiple ports are used for the Xbox and the Modern Warfare 2 game, a

separate forwarding rule is set for each port. Multiple ports and forwarding rules may not

be required for other applications.

Steps

To set up port forwarding for an Xbox:

1.

Click

Advanced

from the main menu.

2. Click

Forwarding

from the left side menu.

3. Enter the Xbox IP address in the

Local IP

field.

4. Define ports used by the Xbox in the

Local Start Port

and

Local End Port

fields.

Define the same ports used by the Xbox in the

External Start Port

and

External End

Port

fields.

5. Create Port Forwarding rules per port. A rule set up for port 53 works for port 53. A

port can be used only by one program at a time.

Note

You can set up applications/services to listen on one internal port. External Internet

users who want to access that application, address it using an external port, such as

an Audio server. Internal Ports are the ports to which local servers listen. External

Ports are the ports that the DDW365 listens to from the WAN.

The following screen shot shows Forwarding set up for an Xbox.

Using the Port Triggers Option

Port Triggers

define dynamic triggers to specific devices on the LAN. This allows special

applications that require specific port numbers with bi-directional traffic to function

properly. Applications such as video conferencing, voice, gaming, and some messaging

program features may require these special settings.

Some services use a dedicated range of ports on the client side and a dedicated range of

ports on the server side. The difference between port forwarding and triggering is:



Port forwarding sets a rule to send a service to a single LAN IP address.



Port triggering defines two kinds of ports: trigger port and target port. The trigger

port sends a service request from a LAN host to a specific destination port number.

The port the LAN host is required to listen to by the application is called the target

port. 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 DDW365

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 DDW365 forwards the traffic to John’s computer IP address.
