3.7.11

Gateway - Forwarding

Port forwarding settings may be required to resolve issues where data is sent out from

a local host to the internet but the return path of expected data is not being received

by your local host. Or, you have an application or service running on your local

network (on a local host) that cannot be accessed from the internet directly (e.g. a

request to a local audio server). Port forwarding simply tells the cable modem to which

computer on the local area network to send the data. Here are some examples:



XBOX/PlaySation

—Some games/applications may require port forwarding.



Home Security Systems

—Some security systems that use the internet may

require port forwarding.



Audio Servers/VOIP

—Port forwarding may be required to fully enable these

applications/services.

Note:

If your host system(s)/applications do

not

have communications issues with

the internet, Forwarding is

not

needed.

You will need two major pieces of information to setup forwarding:



IP address(s) of local host systems

(e.g. XBOX) for which you need to setup a

port forwarding rule. See the continuing discussion below for how to obtain the IP

address(s).



The

port numbers

that a local host’s application listens to for incoming

requests/data (e.g. a game or other service). These port numbers should be

available in the documentation associated with the application. You can also refer

to

http://portforward.com

for more information.

The following tasks are recommended to support the setup of forwarding rules:



Enable UPNP (Universal Plug and Play). This may resolve the issue you have

without the need to set forwarding rules. Access the web interface of the cable

modem, see

page 7

. Select

Gateway

from the top menu, then

Options

from the

left menu. Select the option to enable UPNP. Test your local host/application (e.g.

XBOX) to determine correct functionality. If it is still not properly communicating,

continue with forwarding.



“Tools - Client List” on

page 64

—Use this option to obtain the MAC and IP address

of the internal host for which you are setting up a forwarding rule. You will also

need these for the following task.



“Gateway - Static Lease” on

page 24

—Before setting up forwarding, you are

recommended to 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, you should assign a static IP lease to that system

to keep the IP from renewing and disrupting the forwarding rule.
