2. Network ID (SSID): Network ID is used for identifying the Wireless LAN (WLAN).
Client stations can roam freely over this device and other Access Points that have
the same Network ID. (The factory default setting is “default”)
3. SSID Broadcast: The router will broadcast beacons that have some information,
including SSID so that wireless clients can know how many AP devices by scanning
the network. Therefore, if this setting is configured as “Disable”, the wireless clients
can not find the device from beacons.
4. Channel: The radio channel number. The permissible channels depend on the
Regulatory Domain. The factory default setting is as follow: channel 1~11 for North
America. (Channel 1~13 for European (ETSI); channel1~ 14 for Japan).
5. Wireless Mode: Choose “B/G mixed”, “B only”, “G only”, “N only”, “G/N mixed” or
“B/G/N mixed”. The factory default setting is “B/G/N mixed”.
6. Authentication mode: You may select one of authentication to secure your wireless
network: Open Shared, Auto, WPA-PSK, WPA, WPA2-PSK, WPA2,
WPA-PSK/WPA2-PSK, or WPA /WPA2.
Open
Open system authentication simply consists of two communications. The first is an
authentication request by the client that contains the station ID (typically the MAC
address). This is followed by an authentication response from the AP/router
containing a success or failure message. An example of when a failure may occur is
if the client's MAC address is explicitly excluded in the AP/router configuration.
Shared
Shared key authentication relies on the fact that both stations taking part in the
authentication process have the same "shared" key or passphrase. The shared key
is manually set on both the client station and the AP/router. Three types of shared
key authentication are available today for home or small office WLAN environments.
Auto
The AP will Select the Open or Shared by the client’s request automatically.

3.2.1. Virtual Server
This product’s NAT firewall filters out unrecognized packets to protect your Intranet, so
all hosts behind this product are invisible to the outside world. If you wish, you can make
some of them accessible by enabling the Virtual Server Mapping.
A virtual server is defined as a Service Port, and all requests to this port will be
redirected to the computer specified by the Server IP. Virtual Server can work with
Scheduling Rules, and give user more flexibility on Access control. For the details,
please refer to Scheduling Rule.

3.3.3. URL Blocking
URL Blocking will block LAN computers to connect with pre-define Websites. The
major difference between “Domain filter” and “URL Blocking” is Domain filter require
user to input suffix (like .com or .org, etc), while URL Blocking require user to input a
keyword only. In other words, Domain filter can block specific website, while URL
Blocking can block hundreds of websites by simply a keyword.
1. URL Blocking: Check if you want to enable URL Blocking.
2. URL: If any part of the Website's URL matches the pre-defined word, the connection
will be blocked.
For example, you can use pre-defined word "sex" to block all websites if their URLs
contain pre-defined word "sex".

3.4.2. Dynamic DNS
To host your server on a changing IP address, you have to use dynamic domain name
service (DDNS). So that anyone wishing to reach your host only needs to know the
name of it. Dynamic DNS will map the name of your host to your current IP address,
which changes each time you connect your Internet service provider.
Before you enable Dynamic DNS, you need to register an account on one of these
Dynamic DNS servers that we list in Provider field.
To enable Dynamic DNS click the check box next to Enable in the DDNS field. Next
you have to enter the appropriate information about your Dynamic DNS
Serve .Provider, Host Name, Username/E-mail, and Password/Key. You can get this
information when you register an account on a Dynamic DNS server.

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.
AirLive Air3GII User’s Manual
65
Appendix B. Licensing information
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 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.
66
AirLive Air3GII User’s Manual
Appendix B. Licensing information
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.
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.
AirLive Air3GII User’s Manual
67
Appendix B. Licensing information
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,
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.

Appendix B. Licensing information
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.
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.

Appendix B. Licensing information
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.
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.
