Setting Up Port Forwarding for an Xbox Example
The 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 cable modem listens to from the WAN.

Using the Port Triggers Option
Port Triggers
define dynamic triggers for 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 DVW32CB
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 DVW32CB 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
and enter information in the trigger fields.

Using the DMZ Host Option
Use the
DMZ Host
option to expose a host IP address to the WAN (public Internet). You
can use this option when applications do not work with port triggers or other networking
strategies.
Steps
To set up a DMZ host:
1.
Connect a PC to an Ethernet port on the DVW32CB. 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 DVW32CB.
