Obtain an IP address
automatically
(DHCP Client)
Select this only if your LAN has a DHCP Server. Normally,
it is better for servers to use a Fixed IP address (see below)
Fixed IP Address
This option is recommended. If this option is used, the IP
address or GNS-2000 will never change. You need to
enter the following data.

IP address - The utility will suggest an unused IP
address within the address range used on your LAN. If
you wish, you can change this, but you must ensure the
address is unused.

Network Mask - This must match the value used by
PCs on your LAN.

Gateway - This must match the value used by PCs on
your LAN.
4. Click "Next" to continue. The following screen will then be displayed:
Each interNAS/USB comes with an
unique server name. You may
change it if you wish.
All workgroups on the network are
listed. You may select one from the
pull-down menu, or create a new
one.
Set the proper Time-Zone, Date and
Time here.
The following data is required.
Server Name:
The Default Name is shown. Change this if you wish.
Workgroup
Name:
Normally, this name should match the Workgroup name used by
PCs on your LAN.
12
Time Zone
Select your time zone from the list.
Local
Date/Time
Enter the local date (mm/dd/yyyy format) and time.
5. Click "Next" to continue. The following screen is displayed.
All settings are displayed.

then click “ Save” .
After saving, a final screen will be
displayed.
Click “ Exit” to close the Setup
Utility.
6. Click "Save" to save your data to GNS-2000.
On the resulting screen, click "Exit" to close the Setup Utility. GNS-2000 is now operational.
Other Configuration
After the configuration above, all Windows users can access the NAS with "guest" access
rights. This allows access to the public shares (by default, DISK and FLASH or USB HDD).
However, we recommend creating a GNS-2000 "User" for each person on your LAN. This
will provide each person on your LAN with their own login (name and password) as well as
their own personal folder on GNS-2000.
See the Administration chapter for details on creating users via the Web-based interface.

NAS via the Internet
Overview
If your LAN is connected to the Internet, typically by a Broadband Gateway/Router and
Broadband modem, you can make GNS-2000 available via the Internet. Features available
to Internet users include:

Using a Web browser to view and download files.

Remote management
Making the NAS available via the Internet
If your LAN is connected to the Internet via a Router or Gateway, you can make GNS-2000
available from the Internet.
No changes to the NAS configuration are required, unless you wish to use a port
number other than the default value of 80 for Web connections.
Your Router or Gateway must be configured to pass incoming HTTP connections (and
optionally, IPP connections) to the NAS. This feature is normally called Port Forwarding or
Virtual Servers, and is illustrated below.
Connecting via the Internet
70

The default port number for Web browser connections is 80. If you prefer to use a
different port number, you can specify the port number on the NAS System screen.
The "Web" entry for /Port Forwarding / Virtual Server must then use the port number
specified on the NAS System screen.

To connect to the NAS, Internet users need to know and use the Internet IP address of
your Router/Gateway. (If the port number is not 80, they also need to know the port
number.)

If you have a domain name, users can connect using the domain name instead of the
IP address. If your Router/Gateway supports Dynamic DNS, you can use a domain
name even if you get a different IP address every time you connect to your ISP. Check
the documentation of your Router/Gateway for further information.
Using your Web Browser from the Internet
This is identical to using your Web browser from the LAN. See “Using the Web File Sharing” for details.
But remember:

You must use the Internet IP address to connect to the NAS, NOT the LAN IP address.

If the port number used by the NAS has been changed from the default (80), you must
specify the correct port number when you connect.
For example, if the port is 8080, and the Internet IP address is 203.70.212.52, enter the
following as your browser's Address or Location:
HTTP://203.70.212.52:8080
71
Printing via IPP (Internet Printing Protocol)
To print to GNS-2000 via the Internet, the port used for IPP (TCP port 631) must be associated with GNS-2000. See Making the NAS available via the Internet earlier in this chapter
for details.
The NAS is an IPP Server. To use IPP, your PC must be an IPP client. Windows 2000
and XP have built-in support for IPP, so there is no need to use the provided IPP client
program.
IPP Setup - Windows 2000/XP
1. Start the Add Printer wizard.
2. Select Network Printer, and click "Next" to see the Locate your Printer screen, as
shown below.
Windows 2000 - Locate your Printer
3. Select Connect to a printer on the Internet or on your Intranet, and enter the URL of
GNS-2000 as follows.
http://ip_address:631/printers/printer_name
Where:

ip_address represents the IP Address used to access the NAS. (As explained
earlier, this may be the Internet address of a Gateway, rather than the NAS itself.)

printer_name is the name of the printer, as set on the NAS System screen.

The other text is fixed, and can NOT be changed. It must be entered exactly as
shown, including the same case. (The path is case sensitive.)
Example:
72
http://203.70.212.52:631/printers/LKLKG974163_p1
4. Click "Next"
If the connection can be established, and the printer on that port is on-line, the following dialog will be displayed.
Windows 2000: No printer driver
5.
Click "OK", and then select the printer manufacturer and model to match the printer
connected to the port on the IPP Server.
6. Click "Next", and complete the Wizard.
The IPP printer is now ready for use.
IPP Client Setup (Windows 9x, ME)
You need to install the supplied IPP client program, as follows:
1. Insert the NAS CD-ROM in your drive. If the program does not start automatically, run
the NAS_Setup.exe program in the top-level folder.
2. On the first screen, click the icon for IPP Client.
3. Follow the prompts to complete the installation.
IPP Client Configuration
1. Click the "Add IPP Port" icon. (In future, you can use the program entry created in the
Start Menu)
2. A screen like the following will be displayed.
73
IPP Port
3. Configure this screen as follows:
IPP Server
Enter the Internet IP address used to connect to GNS-2000, as
follows.
http://ip_address:631/printers/printer_name
Where:
 ip_address represents the IP Address used to access the NAS.
(As explained earlier, this may be the Internet address of a Gateway, rather than the NAS itself.)

printer_name is the name of the printer, as set on the NAS
System screen.

The other text is fixed, and can NOT be changed. It must be
entered exactly as shown.
Example:
http://203.70.212.52:631/printers/LKLKG974163_p1
Proxy Server
If Internet access from your PC is via a Proxy Server, check Access
IPP Server via Proxy Server, and enter details of your Proxy Server.
(These will be the same as your Browser configuration, so check
your Browser settings.)
4. Click Save to create the IPP port on your system. You will see the following dialog:
74
Select Printer for IPP Port
5. Either selects an existing printer to use the new port, and click OK.
OR
a) Click the "Add New Printer" button to start the Add Printer wizard.
b) Complete the Wizard, installing the desired printer as a local printer on your PC.
c) When returned to this screen, select the new printer and click OK.
6. The selected printer is now associated with the remote NAS, and installation is complete.
Changing the IPP Port Settings
After the IPP port is created, you can reach the IPP Port screen via the Windows Port
Settings button:
1. Open the Printers folder (Start - Settings - Printers)
2. Right-click the IPP Printer, and select Properties.
3. Locate and click the Port Settings button (on the Details or Port tab, depending on your
version of Windows).
Using the IPP Printer
The IPP Printer can be selected and used like any other Windows printer, but your Internet
connection needs to be active.
An NAS may be unavailable for IPP printing for any of the following reasons:

It is powered off.

The IP Address of the Router/Gateway for the remote LAN has changed.
75

The Internet connection used by the IPP Server is down.

Network congestion causes the connection attempt to time out.
76
Remote Management
Connection via your Web browser from the Internet is the same as connecting via the LAN.
Remember:

You must use the Internet IP address to connect to the NAS, NOT the LAN IP address.

If the port number used by the NAS has been changed from the default (80), you must
specify the correct port number when you connect.
For example, if the port is 8080, and the Internet IP address is 203.70.212.52, enter the
following as your browser's Address or Location:
HTTP://203.70.212.52:8080
Once connected to the NAS via the Internet, all the Web-based management features are
available.
However, the "Browse" button on the Shares screen only allows Web-based file browsing.
(If using Internet Explorer on Windows, LAN users can browse shares using Windows
Explorer.)
77
Troubleshooting
This chapter lists some common problems, and the solution to them.
Problem 1:
The NAS Utility doesn't list any NAS Servers.
Solution 1:
Check the following:

The NAS is installed, LAN connections are OK, and it is powered ON and
startup is complete.

Ensure that your PC and the NAS are on the same network segment. (If
you don't have a router, this must be the case.)

Ensure that your PC has the TCP/IP network protocol loaded. In Windows,
this is done by using Control Panel-Network. If an entry for TCP/IP -> Network card is not listed, use Add - Protocol - Microsoft - TCP/IP to add it.
You then need to select the new entry (TCP/IP -> Network card), click
Properties, and configure the IP Address tab.

If your LAN has a DHCP Server, you can select "Obtain an IP Address
automatically".

Otherwise, you must select "Specify an IP Address", and enter values
for IP Address and Subnet Mask. The IP Address range commonly
used is 192.168.0.1 to 192.168.0.254, with a Subnet Mask of
255.255.255.0. (The NAS Server's default IP Address is 192.168.0.2,
with a Subnet Mask of 255.255.255.0). Remember that each device
needs a unique IP Address, and the same Subnet Mask.
Problem 2:
The NAS is configured, but I can't find it in Network Neighborhood.
Solution 2
Try using Start - Find - Computer, and enter the NAS Server's name. If this
does not work, use Control Panel - Network to check the following:

TCP/IP protocol is installed. If not, use Add - Protocol - Microsoft - TCP/IP
to install it.

Check the network Bindings:

Ensure the TCP/IP protocol is bound to your Network card (NIC).
Select your Network card, click Properties, and then the Bindings tab.
If TCP/IP is not bound (checked), check it.

Ensure the TCP/IP -> Network card entry is bound to the Client for
Microsoft Networks service.
Select the TCP/IP entry for your Network Card, click Properties, and
then the Bindings tab. If Client for Microsoft Networks is not bound
(checked), check it.

If you don't have a router, check that your IP Address is compatible with
the NAS Server's. This means it needs to be from the same address range
(e.g. 192.168.0.1 to 192.168.0.254) and using the same Subnet Mask (e.g.
255.255.255.0)

If you DO have a router, check that your Gateway IP Address is set correctly. Ask your LAN administrator for the correct value.
Problem 3
When I click on an NAS folder icon in Network Neighborhood, I get prompted
for a password.
Solution 3
This can happen in the following situations:

The Logon name you used on your PC is recognized by the NAS, but the
password is not. Simply enter your NAS password, or make your Windows
password the same as the NAS password.
78

The logon name you used on your PC is NOT recognized by the NAS, and
was converted to guest, with guest access rights. Ask the NAS Administrator to create a user name for you. (Use the same name as on your PC.)

You do NOT have access permission for this share.
Ask the NAS Administrator to grant you access.
Note: Windows uses the Computer name, as shown on Control Panel - Network - Identification, as the default Logon Name. But you can create a new
Windows logon name by merely entering a new name and password at the
Logon prompt.

Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but
changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and
change it. By contrast, the GNU General Public License is intended to guarantee your
freedom to share and change free software--to make sure the software is free for all its
users. This General Public License applies to most of the Free Software Foundation's
software and to any other program whose authors commit to using it. (Some other Free
Software Foundation software is covered by the GNU Library General Public License
instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General
Public Licenses are designed to make sure that you have the freedom to distribute copies
of free software (and charge for this service if you wish), that you receive source code or
can get it if you want it, that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these
rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you
must give the recipients all the rights that you have. You must make sure that they, too,
receive or can get the source code. And you must show them these terms so they know
their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this
license which gives you legal permission to copy, distribute and/or modify the software.
83
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by
someone else and passed on, we want its recipients to know that what they have is not the
original, so that any problems introduced by others will not reflect on the original authors'
reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid
the danger that redistributors of a free program will individually obtain patent licenses, in
effect making the program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms
and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE
Terms And Conditions For Copying, Distribution And Modification
0. This License applies to any program or other work which contains a notice placed by
the copyright holder saying it may be distributed under the terms of this General Public
License. The "Program", below, refers to any such program or work, and a "work based
on the Program" means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included
without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License;
they are outside its scope. The act of running the Program is not restricted, and the output
from the Program is covered only if its contents constitute a work based on the Program
(independent of having been made by running the Program). Whether that is true depends
on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you
receive it, in any medium, provided that you conspicuously and appropriately publish on
each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty; and give any other
recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your
option offer warranty protection in exchange for a fee.
84
2. You may modify your copy or copies of the Program or any portion of it, thus forming a
work based on the Program, and copy and distribute such modifications or work under the
terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed
the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains
or is derived from the Program or any part thereof, to be licensed as a whole at no charge
to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must
cause it, when started running for such interactive use in the most ordinary way, to print or
display an announcement including an appropriate copyright notice and a notice that there
is no warranty (or else, saying that you provide a warranty) and that users may redistribute
the program under these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that
work are not derived from the Program, and can be reasonably considered independent
and separate works in themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Program, the distribution of the
whole must be on the terms of this License, whose permissions for other licensees extend
to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is
not the intent of this section to claim rights or contest your rights to work written entirely by
you; rather, the intent is to exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program
(or with a work based on the Program) on a volume of a storage or distribution medium
does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in
object code or executable form under the terms of Sections 1 and 2 above provided that
you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which
must be distributed under the terms of Sections 1 and 2 above on a medium customarily
used for software interchange; or,
85
b) Accompany it with a written offer, valid for at least three years, to give any third party,
for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the
terms of Sections 1 and 2 above on a medium customarily used for software interchange;
or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only
if you received the program in object code or executable form with such an offer, in accord
with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications
to it. For an executable work, complete source code means all the source code for all
modules it contains, plus any associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a special exception,
the source code distributed need not include anything that is normally distributed (in either
source or binary form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component itself accompanies
the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same
place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly
provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under this License will not
have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However,
nothing else grants you permission to modify or distribute the Program or its derivative
works. These actions are prohibited by law if you do not accept this License. Therefore,
by modifying or distributing the Program (or any work based on the Program), you indicate
your acceptance of this License to do so, and all its terms and conditions for copying,
distributing or modifying the Program or works based on it.
86
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify
the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible
for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any
other reason (not limited to patent issues), conditions are imposed on you (whether by
court order, agreement or otherwise) that contradict the conditions of this License, they do
not excuse you from the conditions of this License. If you cannot distribute so as to satisfy
simultaneously your obligations under this License and any other pertinent obligations,
then as a consequence you may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by all those who receive
copies directly or indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is
intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property
right claims or to contest validity of any such claims; this section has the sole purpose of
protecting the integrity of the free software distribution system, which is implemented by
public license practices. Many people have made generous contributions to the wide
range of software distributed through that system in reliance on consistent application of
that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of
the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by
patents or by copyrighted interfaces, the original copyright holder who places the Program
under this License may add an explicit geographical distribution limitation excluding those
countries, so that distribution is permitted only in or among countries not thus excluded. In
such case, this License incorporates the limitation as if written in the body of this License.
87
9. The Free Software Foundation may publish revised and/or new versions of the General
Public License from time to time. Such new versions will be similar in spirit to the present
version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version
number of this License which applies to it and "any later version", you have the option of
following the terms and conditions either of that version or of any later version published by
the Free Software Foundation. If the Program does not specify a version number of this
License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which
is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we
sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing
and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT
WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT
LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR
A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
88
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE
LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL
OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR
A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN
IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
SUCH DAMAGES.
