Select No to disable Internet access.

• Enable NAT: NAT (Network Address Translation) is a system

where one public IP (WAN IP) is used to provide Internet

access to network clients with a private IP address in a LAN.

The private IP address of each network client is saved in a NAT

table and is used to route incoming data packets.

• Enable UPnP: UPnP (Universal Plug and Play) allows several

devices (such as routers, televisions, stereo systems, game

consoles, and cellular phone), to be controlled via an IP-based

network with or without a central control through a gateway.

UPnP connects PCs of all form factors, providing a seamless

network for remote conguration and data transfer. Using

UPnP, a new network device is discovered automatically.

Once connected to the network, devices can be remotely

congured to support P2P applications, interactive gaming,

video conferencing, and web or proxy servers. Unlike Port

forwarding, which involves manually conguring port

settings, UPnP automatically congures the router to accept

incoming connections and direct requests to a specic PC on

the local network.

• Connect to DNS Server: Allows this router to get the DNS

IP address from the ISP automatically. A DNS is a host on

the Internet that translates Internet names to numeric IP

recognized by the ISP.

4.3.2 Port Trigger

Port range triggering opens a predetermined incoming port for a

limited period of time whenever a client on the local area network

makes an outgoing connection to a specied port. Port triggering

is used in the following scenarios:

• More than one local client needs port forwarding for the

same application at a dierent time.

• An application requires specic incoming ports that are

dierent from the outgoing ports.

To set up Port Trigger:

1. From the navigation panel, go to Advanced Settings > WAN >

Port Trigger tab.

2. Congure the following settings below. When done, click

Apply.

• Enable Port Trigger: Choose Yes to enable Port Trigger.

• Well-Known Applications: Select popular games and web

services to add to the Port Trigger List.

• Description: Enter a short name or description for the service.

• Trigger Port: Specify a trigger port to open the incoming port.

• Protocol: Select the protocol, TCP, or UDP.

• Incoming Port: Specify an incoming port to receive inbound

data from the Internet.

• Protocol: Select the protocol, TCP, or UDP.

NOTES:

• WhenconnectingtoanIRCserver,aclientPCmakesanoutgoing

connection using the trigger port range 66660-7000. The IRC server

responds by verifying the username and creating a new connection

to the client PC using an incoming port.

• IfPortTriggerisdisabled,therouterdropstheconnectionbecause

it is unable to determine which PC is requesting for IRC access.

When Port Trigger is enabled, the router assigns an incoming port to

receive the inbound data. This incoming port closes once a specic

time period has elapsed because the router is unsure when the

application has been terminated.

• Porttriggeringonlyallowsoneclientinthenetworktousea

particular service and a specic incoming port at the same time.

• Youcannotusethesameapplicationtotriggeraportinmorethan

one PC at the same time. The router will only forward the port back

to the last computer to send the router a request/trigger.

4.3.3 Virtual Server/Port Forwarding

Port forwarding is a method to direct network trac from the

Internet to a specic port or a specic range of ports to a device

or number of devices on your local network. Setting up Port

Forwarding on your router allows PCs outside the network to

access specic services provided by a PC in your network.

NOTE: When port forwarding is enabled, the ASUS router blocks

unsolicited inbound trac from the Internet and only allows replies

from outbound requests from the LAN. The network client does not

have access to the Internet directly, and vice versa.

To set up Port Forwarding:

1. From the navigation panel, go to Advanced Settings > WAN >

Virtual Server / Port Forwarding tab.

2. Congure the following settings below. When done, click

Apply.

• Enable Port Forwarding: Choose Yes to enable Port

Forwarding.

• Famous Server List: Determine which type of service you

want to access.

• Famous Game List: This item lists ports required for popular

online games to work correctly.

• FTP Server Port: Avoid assigning the port range 20:21 for

your FTP server as this would conict with the router’s native

FTP server assignment.

• Service Name: Enter a service name.

• Port Range: If you want to specify a Port Range for clients

on the same network, enter the Service Name, the Port

Range (e.g. 10200:10300), the LAN IP address, and leave the

Local Port empty. Port range accepts various formats such

as Port Range (300:350), individual ports (566,789) or Mix

(1015:1024,3021).

NOTES:

• Whenyournetwork’srewallisdisabledandyouset80astheHTTP

server’s port range for your WAN setup, then your http server/web

server would be in conict with the router’s web user interface.

• Anetworkmakesuseofportsinordertoexchangedata,witheach

port assigned a port number and a specic task. For example, port 80

is used for HTTP. A specic port can only be used by one application

or service at a time. Hence, two PCs attempting to access data

through the same port at the same time would fail. For example, you

cannot set up Port Forwarding for port 100 for two PCs at the same

time.

• Local IP: Key in the client’s LAN IP address.

NOTE: Use a static IP address for the local client to make port forwarding

work properly. Refer to section 4.2 LAN for information.

• Local Port: Enter a specic port to receive forwarded packets.

Leave this eld blank if you want the incoming packets to be

redirected to the specied port range.

• Protocol: Select the protocol. If you are unsure, select BOTH.

To check if Port Forwarding has been congured successfully:

• Ensure that your server or application is set up and running.

• You will need a client outside your LAN but has Internet

access (referred to as “Internet client”). This client should not

be connected to the ASUS router.

• On the Internet client, use the router’s WAN IP to access the

server. If port forwarding has been successful, you should be

able to access the les or applications.

Dierences between port trigger and port forwarding:

• Port triggering will work even without setting up a specic

LAN IP address. Unlike port forwarding, which requires a

static LAN IP address, port triggering allows dynamic port

forwarding using the router. Predetermined port ranges are

congured to accept incoming connections for a limited

period of time. Port triggering allows multiple computers

to run applications that would normally require manually

forwarding the same ports to each PC on the network.

• Port triggering is more secure than port forwarding since the

incoming ports are not open all the time. They are opened

only when an application is making an outgoing connection

through the trigger port.

4.3.4 DMZ

Virtual DMZ exposes one client to the Internet, allowing this

client to receive all inbound packets directed to your Local Area

Network.

Inbound trac from the Internet is usually discarded and routed

to a specic client only if port forwarding or a port trigger has

been congured on the network. In a DMZ conguration, one

network client receives all inbound packets.

Setting up DMZ on a network is useful when you need incoming

ports open or you want to host a domain, web, or e-mail server.

under the terms of the GNU General Public License. Please see The

GNU General Public License for the exact terms and conditions of

this license. All future rmware updates will also be accompanied

GNU GENERAL PUBLIC LICENSE

Version 2, June 1991

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.

114

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) oer you this license which gives you legal permission to

115

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 modied 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 reect 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 eect 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

modication follow.

Terms & conditions for copying, distribution, & modication

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 modications and/or translated into another language.

(Hereinafter, translation is included without limitation in the

term “modication”.) Each licensee is addressed as “you”.

Activities other than copying, distribution and modication 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

116

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 oer 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 modications or work under the

terms of Section 1 above, provided that you also meet all of

these conditions:

a) You must cause the modied les to carry prominent

notices stating that you changed the les 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 modied 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

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.)

117

These requirements apply to the modied work as a whole.

If identiable 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,

b) Accompany it with a written oer, 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

oer to distribute corresponding source code. (This alternative

is allowed only for noncommercial distribution and only if you

118

received the program in object code or executable form with

such an oer, in accord with Subsection b above.)

The source code for a work means the preferred form of

the work for making modications to it. For an executable

work, complete source code means all the source code for all

modules it contains, plus any associated interface denition

les, 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

oering access to copy from a designated place, then oering

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

119

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.

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.

120

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 dier in detail to address new problems or concerns.

Each version is given a distinguishing version number. If the

Program species 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 dierent, 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.

121

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.
