How to access files remotely
To access files remotely, you must first attach a USB drive to your router and set
up that storage for remote access° For instructions, see “How to configure your
router’s storage for remote access” on page 36° You can then access files from
anywhere on the Internet°
To access files remotely:
1.
Make sure that your router is configured to share files° For more
information, see “How to configure your router’s storage for remote
access” on page 36°
2.
Make sure that your router has user accounts set up, and that you have
taken note of the user name and password you will use to access the
router’s storage° If you have enabled Anonymous FTP (not recommended),
you will not need a user name and password° For more information, see
“How to configure storage” on page 32°
3.
Take note of the IP address of your router° To view your router’s IP address,
open the browser-based utility, click the
Status
tab, then click the
Router
page and take note of the numbers in the
Internet IP Address
field°
– OR –
If you have
DDNS
(Dynamic Domain Name Service), take note of the
domain name registered to your router° For more information, see “How
to find your network on the Internet” on page 16°
4.
At any remote location where you can access the Internet, you can:
•
Use FTP (File Transfer Protocol) client software to connect to your
router° You will need to enter your router’s IP address° If access to your
router requires a user name and password, you will also need to enter
those details° For more information on using the FTP client software,
see its documentation or help°
– OR –
•
Type the router’s IP address into a web browser’s Internet address
field, press
Enter
, then enter your user name and password°
FTP software and web browsers display FTP content in many ways,
but you can usually use these common actions to navigate through
FTP folders:
•
Click a folder name to open it°
•
Click a double period (°°) or
Up to a higher level directory
to
open a parent folder°
•
Click or right-click a file to download or view it°
•
Drag a file from another window and drop it into the FTP window
to upload it° (To upload a file, your user account must have write
access°)

How to set up port forwarding
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 40)
•
A range of ports (see “How to set up port forwarding for a range of ports”
on page 40)
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 15)°
2.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 14)°
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°

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 14)°
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 15)°
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°

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 14)°
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 15)° 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
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 14)°
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°

How to configure your Xbox for online
gaming
Why would I set up my Xbox for online gaming?
Online gaming adds another
dimension to using your Xbox° As with other online gaming applications and
gaming consoles, you need to forward multiple ports to use your Xbox for
online gaming° The procedure for setting up your Xbox is almost identical to
setting up multiple port forwarding for VNC remote control° (See “How to set
up port forwarding for multiple ports” on page 40)°
NOTE
For more information on configuring your router for online gaming,
see “How to optimize your router for gaming and voice” on page 19°
Refer to your game console documentation to determine the ports used by
your device° The Xbox uses four ports:
•
TCP port 80
•
UDP port 88
•
TCP/UDP port 53
•
TCP/UDP port 3074
To set up an Xbox using multiple entries of single port forwarding:
Applications & Gaming > Single Port Forwarding
1.
Connect your Xbox 360 to your router°
1.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 14)°
2.
Set up a DHCP reservation for the IP address of the Xbox° (See “How to set
up the DHCP server on your router” on page 15)°
– OR –
Refer to your game console’s documentation to set a static IP address for
your device°
3.
Click the
Applications & Gaming
