How to connect your UPnP device to the media server

After you set up your router’s media server, you need to connect an UPnP-

compatible device (such as an UPnP-compatible game console or digital media

player) to the network so that you can play the media server’s content°

To connect an UPnP device to your router’s media server:

1.

Connect your UPnP device to your home network with wired (Ethernet

cable) or wireless networking° If you are connecting wirelessly, you

need to know your network’s name and password° See your device’s

documentation for help°

2.

On your UPnP device, change the media source to the media server

name you specified on your router° (See “How to set up your router as a

media server” on page 50)

3.

See your UPnP device’s documentation for help with playing media on

the device°

How to set up port forwarding

For

ALL

Why would I use port forwarding? Port forwarding is a feature that forwards

inbound traffic from the Internet on a specific port or ports to a specific device

or port on your local network° You can set up port forwarding for:

•

A single port (see “How to set up port forwarding for a single port” below)

•

Multiple ports (see “How to set up port forwarding for multiple ports” on

page 54)

•

A range of ports (see “How to set up port forwarding for a range of ports”

on page 54)

How to set up port forwarding for a single port

Why would I use port forwarding for a single port?

Single port forwarding

is a feature that forwards inbound traffic from the Internet on a specific port to

a single device on your local network° An example of single port forwarding

would be to forward inbound web requests, typically on port 80, to a web

server°

To set up single port forwarding:

Applications & Gaming > Single Port Forwarding

1.

Follow your device’s instructions for configuring it with a static IP address

or use DHCP reservation to assign it a permanent address (see “How to

set up the DHCP server on your router” on page 26)°

2.

Log into the browser-based utility (see “How to open the browser-based

utility” on page 22)°

3.

Click the

Applications & Gaming

tab, then click the

Single Port

Forwarding

page°

4.

Select the type of application from the

Application Name

drop-down

list° One of the more common types to select is

HTTP

, but see your

device’s documentation for recommendations°

5.

In the

To IP Address

field, enter the last three digits of the IP address you

have reserved for the computer you want to forward Internet traffic to°

The rest of the IP address has already been completed for you°

6.

Select

Enabled

next to the

IP Address field

°

7.

Click

Save Changes

at the bottom of the screen°

TIP

For other devices not included in the Application Name drop-

down list, see the device’s documentation for port and protocol

information°

How to set up port forwarding for multiple ports

Why would I set up port forwarding for multiple ports?

Port forwarding is

a feature that forwards inbound traffic from the Internet on a specific port to

a single device on your local network° Unlike a web camera that typically only

requires a single port to be forwarded, some applications require forwarding

of multiple ports°

VNC

(Virtual Network Computing) software that allows you to

operate your computer remotely from anywhere on the Internet is an example

of an application that requires multiple ports to be forwarded° To forward to

multiple ports, just create additional entries to forward additional ports to the

same IP address°

Example

: You want to set up your computer so you can remotely access it using

VNC software° By default, VNC uses TCP ports 5800 and 5900°

To set up single port forwarding for multiple ports:

Applications & Gaming > Single Port Forwarding

1.

Make sure that the software you want to use has been installed onto a

networked computer°

2.

Log into the browser-based utility (see “How to open the browser-based

utility” on page 22)°

3.

Set up DHCP reservation for the IP address of the computer on which

you installed the software° (See “How to set up the DHCP server on your

router” on page 26)°

4.

Click the

Applications & Gaming

tab, then click the

Single Port

Forwarding

page°

5.

For each entry, enter a descriptive name in the

Application Name

field°

6.

For each entry, enter in the same port number for the

External Port

and

the

Internal Port

°

7.

In the

To IP Address

field, enter the last three digits of the IP address you

have reserved for the computer you want to forward Internet traffic to°

The rest of the IP address has already been completed for you°

8.

Select

Enabled

next to the

IP Address

field°

9.

Click

Save Changes

at the bottom of the screen°

NOTE

If you want to use software such as VNC on multiple computers,

you will need to reconfigure the default ports that VNC uses on

each additional computer° Then, create additional port forwarding

entries for each additional computer° See your software’s

documentation for help°

How to set up port forwarding for a range of ports

Why would I set up port forwarding for a range of ports?

Port forwarding is

a feature that forwards inbound traffic from the Internet on a range of ports to

a single device on your local network° Unlike a web camera that typically only

requires a single port to be forwarded, some applications require forwarding

to a range of ports°

Example

: You want to set up your computer so you can use BitTorrent, a

popular peer-to-peer file sharing application° BitTorrent uses port 6881 by

default° If that port is busy, the requesting BitTorrent client tries the next port

in sequence° The most common configuration for home routers with a single

BitTorrent computer is to set up port forwarding using a range of ports starting

with 6881 and ending with port 6889°

Port Forwarding and Port Triggering

Linksys E-Series

To set up port range forwarding:

Applications & Gaming > Port Range Forwarding

1.

Log into the browser-based utility (see “How to open the browser-based

utility” on page 22)°

2.

Set up a DHCP reservation for the IP address of the computer on which

you installed the software° (See “How to set up the DHCP server on

your router” on page 26)° In this example, the IP address of the desktop

computer with BitTorrent installed is 192°168°1°140°

3.

Click the

Applications & Gaming

tab, then click the

Port Range

Forwarding

page°

4.

Enter a descriptive name, then enter the

Start Port

and the

End Port

values to specify the range° In this example, the range is 6881 to 6889°

5.

Select

TCP

as the protocol°

6.

In the

To IP Address

field, enter the last 3 digits of the IP address of the

device running the software° The rest of the IP address fields already

completed° In this example, you would enter 140°

7.

Select

Enabled

next to the

To IP Address

field°

8.

Click

Save Settings

at the bottom of the page°

NOTES:

To use software like BitTorrent on multiple computers on your

network, create additional entries with a unique range of ports as

shown above° BitTorrent only works with ports between 6881 and

6999°

Depending on your computer’s firewall software, you may need to

open a range of ports in your firewall to enable software that uses

port range forwarding

How to set up port range triggering for

online gaming

For

ALL

Why would I use port triggering instead of port forwarding?

Port range

triggering allows the router to watch outgoing data for specific port numbers°

The IP address of the computer that sends the matching data is remembered

by the router, so that when the requested data returns through the router,

the data is routed back to the proper computer° An example of port range

triggering would be to enable a USB or Bluetooth headset for online chat and

gaming°

To set up port range triggering for multiple entries:

Applications & Gaming > Port Range Triggering

1.

Log into the browser-based utility (see “How to open the browser-based

utility” on page 22)°

2.

Click the

Applications & Gaming

tab, then click the

Port Range

Triggering

page°

3.

See your device documentation for information on the ports that the

device uses°

4.

For each entry in the

Port Range Forwarding

table:

•

Enter a descriptive name (such as

PS3 Headset

)

•

For single ports, enter the same port number in each

Triggered Range

and

Forwarded Range

box°

•

For port ranges, enter the same number ranges in each

Triggered

Range

and

Forwarded Range

column°
