Using the Forwarding Option

Forwarding tells the DVW32CB to which computer on the local area network to send data.

If your host systems or applications have communications issues with the Internet, you

can use forwarding to resolve the following issues:



Data is sent from a local host to the Internet, but the return path of expected data is

not received by your local host.



An application or service running on your local network (on local host) cannot be

accessed from the Internet directly (for example, a request to a local audio server).

Examples are:



Xbox/PlayStation

–

Games/applications



Home Security Systems

–

Security systems that use the Internet



Audio Servers/VoIP

–

Audio and VoIP applications and services

Before Setting Up Forwarding

Try the following options before you assign forwarding rules:

1.

Enable Universal Plug and Play (UPnP). This may resolve the issue you have without

setting up forwarding rules.

a.

Access the Web interface of the DVW32CB, see

Accessing the Web User Interface

Locally on page 14

.

f.

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 53

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 port forwarding:

1.

Access the Web interface of the DVW32CB, see

Accessing the Web User Interface

Locally on page 14

.

2. Click

Advanced

from the main menu.

3. Click

Forwarding

from the left menu.

4. Click either

Create IPv4

or

Create IPv6
