e. Test your local host or application such as your Xbox to see if it is functioning
properly. Continue with port forwarding if the host or application is not
communicating correctly.
2. Assign a Static IP lease to the client/host to which you are setting up forwarding. This
way, the IP does not change and disrupt your forwarding rules. For example, if you are
hosting a Web server in your internal network, and you wish to setup a forwarding rule
for it, assign a static IP lease to that system to keep the IP from renewing and
disrupting the forwarding rule.
6.5.2
Setting Up Forwarding
If the suggestions in
Before Setting Up Forwarding on page 46
did not correct your
communication problem, use port forwarding.
You need the following information to set up port forwarding:
IP address
of each local host system (for example, Xbox) for which you need to setup
a port forwarding rule.
Port numbers
the local host’s application listens to for incoming requests/data (for
example, a game or other service). These port numbers should be available in the
documentation associated with the application.
Note
For detailed information on port forwarding, including how to set it up for specific
applications using specific network devices (for example, cable modems), refer to:
http://portforward.com
or consult your host device or application user manual.
Steps
To set up forwarding:
1.
Access the Web interface of the DVW326, see
Accessing the Web User Interface
Locally on page 18
.
2. Click
Advanced
from the main menu.
3. Click
Forwarding
from the left menu.
4. Click

descriptions follow.
Label
Description
Local IP
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
Designates the IP address of another router on the network
through which to forward data.

. The forwarding rule is created and displayed in the table as shown
below. Additional field descriptions follow.
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.

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 DVW326 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 DVW326
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 DVW326 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
expires.
Steps
To set up port triggering:
1.
Click
Advanced
from the main menu.
2. Click
Port Triggers
from the left side menu.
3. Click
Create.
