How to access files remotely
For
E3200
E4200
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 52° 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 52°
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 48°
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 30°
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 your router as a media
server
For
E4200
What is a media server and how would I use it?
A media server lets you share
media content across your network° Your router can act as a media server if it
has a USB drive attached and if you have UPnP AV (Audio and Video)-enabled
or DLNA (Digital Living Network Alliance)-certified devices in your home°
Examples of UPnP AV-enabled devices include digital media players, gaming
consoles with a built-in media player, and digital picture frames°
For example, if you have a digital media adapter that sends content to your
entertainment system, and if your router’s set up as a media server, then the
digital media adapter can access your router’s attached USB drive°
You can specify which folders are used by the media server, add and delete
folders, and specify how often the folders are scanned for new content°
To configure your router as a media server:
Storage > Media Server
1.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 25)°
2.
Click the
Storage
tab, then click the
Media Server
page°
3.
Click
Enabled
to enable the media server°

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 54)
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 58)
A range of ports (see “How to set up port forwarding for a range of ports”
on page 58)
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 29)°
2.
Log into the browser-based utility (see “How to open the browser-based
utility” on page 25)°
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

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 25)°
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 29)°
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°
