Version 2, June 1991

Everyone is permitted to copy and distribute verbatim copies of this

license document, but changing it is no t all ow ed.
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, w e 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 t hat 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.

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 n ot 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 pr ogram 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 w hat the Program does.

1. You may copy and distribute verbatim copies of the Pr ogram's
source code as you receive it, in any medium, provided th at you
conspicuously and appropriately publish on each c opy 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 wa rranty protection in exchange for a
fee.

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 tha t 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 par ties under the terms of this
License.

c) If the modified program norm a lly 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 provide d that you also do one of the fo llowing:

a) Accompany it with the complete corresponding
machine-readable source code, which must be distributed
under the terms of Sections 1 a nd 2 above on a medium
customarily used for softw a re interchange; or,

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 abo ve 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, m odify, 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 ha ve 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 conditio ns for copying, distributi ng or modifying the
Program or works based on it.

6. Each time you redistribut e 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 y ou (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 d irectly or indirectly through you, then
the only way you could sat isfy 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 contes t validity of any such
claims; this section has the sole purpose of protecting the integrity of
the free software distribution system, which is im plemented 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 writte n in the body of this License.

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 p a rts 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 softw a re 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, 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.

 Route power supply cords where they are not likely to be

walked on or pinched by items placed on or against them. Pay
particular attention to cords where they are attached to plugs
and convenience receptacles, and examine the point where
they exit the unit.

 Do not connect or disconnect power supply cables and data

transmission lines during thunderstorms.

 Do not overload wall outlets or extension cords, as this can

result in a risk of fire or electric shock. Overloaded AC outlets,
extension cords, frayed power cords, damaged or cracke d wire
insulation, and broken plugs are dangerous. They may result in
a shock or fire hazard. Periodically examine the cord, and if its
appearance indicates dama ge or deteriorated insulation, have it
replaced by your service techn ician.

About Your D-Link NetDefend firewall

The D-Link NetDefend firewall is a unified threat management (UTM) appliance
that enables secure high-speed Internet access from the office. Incorporating
software by SofaWare Technologies, an affiliate of Check Point Software
Technologies, the worldwide leader in securing the Internet, the NetDefend
Secured by Check Point Product Family includes both wired and wireless models.
The D-Link firewall, based on the world-leading Check Point Embedded NGX
Stateful Inspection technology, inspects and filters all incoming and outgoing
traffic, blocking all unauthorized traffic.

The NetDefend firewall also allows sharing your Internet connection among
several PCs or other network devices, enabling advanced office networking and
saving the cost of purchasing static IP addresses.

With the NetDefend firewall, you can subscribe to additional security services
available from select service providers, including firewall security and software
updates, Antivirus, Web Filtering, reporting, and VPN management. By supporting
integrated VPN capabilities, the NetDefend firewall allows teleworkers and road
warriors to securely connect to the office network, and enables secure
interconnection of branch offices.
