• For source or destination port range, you can either:

a) Enter a specic port, such as “95”.

b) Enter ports within a range, such as “103:315”, “>100”, or

“<65535”.

• The Transferred column contains information about the upstream

and downstream trac (outgoing and incoming network trac) for
one section. In this column, you can set the network trac limit (in
KB) for a specic service to generate specic priorities for the service
assigned to a specic port. For example, if two network clients, PC
1 and PC 2, are both accessing the Internet (set at port 80), but PC 1
exceeds the network trac limit due to some downloading tasks, PC
1 will have a lower priority. If you do not want to set the trac limit,
leave it blank.

37

5. On the User-dened Priority page, you can prioritize the
network applications or devices into ve levels from the user-

dened QoS rules’ dropdown list. Based on priority level, you
can use the following methods to send data packets:

• Change the order of upstream network packets that are sent
to the Internet.

• Under Upload Bandwidth table, set Minimum Reserved
Bandwidth and Maximum Bandwidth Limit for multiple
network applications with dierent priority levels. The
percentages indicate the upload bandwidth rates that are
available for specied network applications.

NOTES:

• Low-priority packets are disregarded to ensure the transmission of
high-priority packets.

• Under Download Bandwidth table, set Maximum Bandwidth
Limit for multiple network applications in corresponding order.
The higher priority upstream packet will cause the higher priority
downstream packet.

• If there are no packets being sent from high-priority applications, the
full transmission rate of the Internet connection is available for low­priority packets.

6. Set the highest priority packet. To ensure a smooth online

gaming experience, you can set ACK, SYN, and ICMP as the
highest priority packet.

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.

76

• 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.

77

4.3.4 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.

78

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

• Enable Port Forwarding: Turn ON 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.

79

• 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.

80

4.3.5 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.

CAUTION! Opening all the ports on a client to the Internet makes the
network vulnerable to outside attacks. Please be aware of the security
risks involved in using DMZ.

To set up DMZ:

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

2. Congure the setting below. When done, click Apply.

• IP address of Exposed Station: Key in the client’s LAN IP
address that will provide the DMZ service and be exposed
on the Internet. Ensure that the server client has a static IP
address.

To remove DMZ:

1. Delete the client’s LAN IP address from the IP Address of
Exposed Station text box.

2. When done, click Apply.

81

4.3.6 DDNS

Setting up DDNS (Dynamic DNS) allows you to access the router
from outside your network through the provided ASUS DDNS
Service or another DDNS service.

To set up DDNS:

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

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

• Enable the DDNS Client: Enable DDNS to access the ASUS
router via the DNS name rather than WAN IP address.

• Server and Host Name: Choose ASUS DDNS or other DDNS.
If you want to use ASUS DDNS, ll in the Host Name in the
format of xxx.asuscomm.com (xxx is your host name).

• If you want to use a dierent DDNS service, click FREE TRIAL
and register online rst. Fill in the User Name or E-mail
Address and Password or DDNS Key elds.

82

• Enable wildcard: Enable wildcard if your DDNS service
requires one.

NOTES:

DDNS service will not work under these conditions:

• When the wireless router is using a private WAN IP address (192.168.
x.x, 10.x.x.x, or 172.16.x.x), as indicated by a yellow text.

• The router may be on a network that uses multiple NAT tables.

4.3.7 NAT Passthrough
