Chapter 1
Introduction
1.1 Introducing the BEC 7300N
Thank you for purchasing the BEC 7300N Router. Your new router is an all-in-one unit that
combines an ADSL modem, ADSL2/2+ router and Ethernet network switch to provide
everything you need to get the machines on your network connected to the Internet over an
ADSL broadband connection.
The BEC 7300N router complies with ADSL2+ standards for deployment worldwide and
supports downstream rates of up to 24 Mbps and upstream rates of up to 1 Mbps. Designed
for small office, home office and residential users, the router enables even faster Internet
connections. You can enjoy ADSL services and broadband multimedia applications such as
interactive gaming, video streaming and real-time audio much easier and faster than ever
before.
The BEC 7300N supports PPPoA (RFC 2364 – PPP (Point-to-Point Protocol) over ATM
Adaptation Layer 5), RFC 1483 encapsulation over ATM (bridged or routed), PPP over
Ethernet (RFC 2516) to establish a connection with your ISP. Your new router also supports
VC-based and LLC-based multiplexing.
The perfect solution for connecting a small group of PCs to a high-speed broadband Internet
connection, the BEC 7300N allows multiple users to have high-speed Internet access
simultaneously.
Your new router also serves as an Internet firewall, protecting your network from access by
outside users. Not only does it provide a natural firewall function with Network Address
Translation (NAT), it also provides rich firewall features to secure your network. All incoming
data packets are monitored and filtered. You can also configure your new router to block
internal users from accessing the Internet.
4
The BEC 7300N provides two levels of security support. First, it masks LAN IP addresses
making them invisible to outside users on the Internet, so it is much more difficult for a
hacker to target a machine on your network. Second, it can block and redirect certain ports
to limit the services that outside users can access. To ensure that games and other Internet
applications run properly, you can open specific ports for outside users to access internal
services on your network.
The Integrated DHCP (Dynamic Host Control Protocol) client and server services allow
multiple users to get IP addresses automatically when the router boots up. Simply set local
machines as a DHCP client to accept a dynamically assigned IP address from the DHCP
server and reboot. Each time a local machine is powered up; the router recognizes it and
assigns an IP address to instantly connect it to the LAN.
For advanced users, Virtual Service (port mapping) functions allow the product to provide
limited visibility to local machines with specific services for outside users. For instance, a
dedicated web server can be connected to the Internet via the router and then incoming
requests for web pages that are received by the router can be rerouted to your dedicated
local web server, even though the server now has a different IP address.
Virtual Server can also be used to re-task services to multiple servers. For instance, you can
set the router to allow separated FTP, Web, and Multiplayer game servers to share the same
Internet-visible IP address while still protecting the servers and LAN users from hackers.

1.2 Features
Express Internet Access – ADSL2/2+ capable
The BEC 7300N complies with ADSL worldwide standards. Supporting downstream rates of
8Mbps with ADSL, the router is capable of up to 12/24 Mbps with ADSL2/2+, and upstream
rates of up to 1 Mbps. Users enjoy not only high-speed ADSL services but also broadband
multimedia applications such as interactive gaming, video streaming and real-time audio
which are easier and faster than ever. The router is compliant with Multi-Mode standard
(ANSI T1.413, Issue 2; G.dmt (ITU G.992.1); G.hs (ITU G994.1); G.dmt.bis (ITU G.992.3);
and G.dmt.bisplus (ITU G.992.5)
802.11n Wireless AP with WPA Support
With integrated 802.11n Wireless Access Point in the router, the device offers a quick and
easy access among wired network, wireless network and broadband connection (ADSL)
with single device simplicity, and as a result, mobility to the users. In addition to 300 Mbps
802.11n data rate, it also interoperates backward with existing 802.11g and 802.11b
equipment. The Wireless Protected Access (WPA) and Wireless Encryption Protocol (WEP)
supported features enhance the security level of data protection and access control via
Wireless LAN.
Fast Ethernet Switch
A 4-port 10/100Mbps fast Ethernet switch is built-in with automatic switching between MDI
and MDI-X for 10Base-T and 100Base-TX ports, with auto detection allowing you to use
either straight or cross-over Ethernet cables.
EWAN
Besides using ADSL to get connected to the Internet, BEC 7300N offers its Ethernet port 1
as a WAN port to be used to connect to Cable Modems, VDSL and fibre optic lines. This
alternative, yet faster method to connect to the internet will provide users more flexibility to
get online.
Multi-Protocol to Establish a Connection
The router supports PPPoA (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM (bridged or routed), PPP over Ethernet (RFC 2516) to establish a
connection with an ISP. The router also supports VC-based and LLC-based multiplexing.
6
Universal Plug and Play (UPnP) and UPnP NAT Traversal
This protocol is used to enable simple and robust connectivity among stand-alone devices
and PCs from many different vendors, and it makes setting up a network simple and
affordable. UPnP architecture leverages TCP/IP and the Web to enable proximity
networking in addition to control and data transfer among networked devices. With this
feature enabled, you can seamlessly connect to Net Meeting or MSN Messenger.
Network Address Translation
Network Address Translation (NAT) allows multiple users to access outside resources such
as the Internet simultaneously with one IP address/one Internet access account. Many
application layer gateways (ALG) are supported such as web browser, ICQ, FTP, Telnet,
E-mail, News, Net2phone, Ping, NetMeeting, IP phone and others.
Firewall
NAT technology supports simple firewalls and provides options for blocking access from the
Internet, like Telnet, FTP, TFTP, WEB, SNMP and IGMP.
Domain Name System Relay
Domain Name System (DNS) relay provides an easy way to map a domain name with a
user-friendly name such as www.google.com with an IP address. When a local machine
sets its DNS server to the router’s IP address, every DNS conversion request packet from
the PC to this router is forwarded to the real DNS on the outside network.
Dynamic Domain Name System (DDNS)
The Dynamic DNS service allows you to alias a dynamic IP address to a static hostname.
This dynamic IP address is the WAN IP address. To use the service, you must first apply for
an account from a DDNS service such as http://www.dyndns.org/.
PPP over Ethernet (PPPoE)
The BEC 7300N provides an embedded PPPoE client function to establish a connection.
You get greater access speed without changing the operation concept, while sharing the
same ISP account and paying for one access account. No PPPoE client software is required
for the local computer. Automatic Reconnect and Disconnect Timeout (Idle Timer) functions
are also provided.
Quality of Service (QoS)
7
QoS gives you full control over which types of outgoing data traffic should be given priority
by the router, ensuring important data like gaming packets, customer information, or
management information move through the router ay lightning speed, even under heavy
load. The QoS features are configurable by Internal IP address, External IP address,
protocol, and port. You can throttle the speed at which different types of outgoing data pass
through the router, to ensure P2P users don’t saturate upload bandwidth, or office browsing
doesn’t bring client web serving to a halt. In addition, or alternatively, you can simply change
the priority of different types of upload data and let the router sort out the actual speeds.
Virtual Server:
You can specify which services are visible to outside users. The router detects an incoming
service request and forwards it to the specific local computer for handling. For example, you
can assign a PC in a LAN to act as a Web server inside and expose it to the outside network.
Outside users can browse inside the web server directly while it is protected by NAT. A DMZ
host setting is also provided for local computers exposed to the outside Internet network.
Dynamic Host Configuration Protocol (DHCP) Client and Server
On a WAN site, the DHCP client obtains an IP address from the Internet Service Provider
(ISP) automatically. On a LAN site, the DHCP server allocates a range of client IP
addresses, including subnet masks and DNS IP addresses and distributes them to local
computers. This provides an easy way to manage the local IP network.
Rich Packet Filtering
This feature filters the packet based on IP addresses as well as Port numbers. Filtering
packets to and from the Internet provides a higher level of security control.
Web-based GUI
A web-based GUI offers easy configuration and management. It also supports remote
management capability for remote users to configure and manage this product.
Firmware Upgradeable
You can upgrade the router with the latest firmware through its web-based GUI.

Chapter 2
Product Overview
Standards-Based Technology
The BEC 7300N Wireless Router utilizes the 802.11n standard. The IEEE 802.11n standard
is an extension of the 802.11g standard. It increases the data rate up to 300 Mbps within the
2.4GHz band, utilizing OFDM technology. This means that in most environments, within the
specified range of this device, you will be able to transfer large files quickly or even watch a
movie in MPEG format over your network without noticeable delays. This technology works
by transmitting high-speed digital data over a radio wave utilizing OFDM (Orthogonal
Frequency Division Multiplexing) technology. OFDM works by splitting the radio signal into
multiple smaller sub-signals that are then transmitted simultaneously at different frequencies
to the receiver. OFDM reduces the amount of crosstalk (interference) in signal
transmissions.
Installation Considerations
The BEC 7300N Wireless Router lets you access your network, using a wireless connection,
from virtually anywhere within its operating range. Keep in mind, however, that the number,
thickness and location of walls, ceilings, or other objects that the wireless signals must pass.
Keep the number of walls and ceilings between the BEC 7300N and other network devices
to a minimum - each wall or ceiling can reduce your BEC 7300N wireless product’s range
from 3-90 feet (1-30 meters.)
Position your devices so that the number of walls or ceilings is minimized. Be aware of the
direct line between network devices. Position the devices so that the signal will travel
straight through a wall or ceiling (instead of at an angle) for better reception. Building
Materials can impede the wireless signal - a solid metal door or aluminium studs may have a
negative effect on range.
Try to position wireless devices and computers with wireless adapters so that the signal
passes through drywall or open doorways and not other materials. Keep your product away
(at least 3-6 feet or 1-2 meters) from electrical devices or appliances that generate extreme
RF (radio frequency) noise.

1. Recovery procedures for non-working routers (e.g. after a failed firmware upgrade flash):
Hold the Reset Button on the back of the modem in. Keep this button held in and turn on the
modem. Once the lights on the modem have stopped flashing, release the Reset Button.
The modem's emergency-reflash web interface will then be accessible via
http://192.168.1.1 where you can upload a firmware image to restore the modem to a
functional state. Please note that the modem will only respond via its web interface at this
address, and will not respond to ping requests from your PC or to telnet connections.
Before powering on the router to enter the recovery process, please
configure the IP address of the PC as 192.168.1.100 and proceed with
the following step by step guide.
1. Power the router off.
2. Hold the "Reset Button”.
3. Power on the router. Then Router's IP will reset to Emergency IP
address (Say 192.168.1.1)
4. Download the firmware.
2.5 Cabling
One of the most common causes of problems is because of bad cabling or ADSL line(s).
14
Make sure that all connected devices are turned on. On the front of the product is a bank of
LEDs. Verify that the LAN Link and ADSL line LEDs are lit. If they are not, verify that you are
using the proper cables.
Ensure that all other devices connected to the same telephone line as your router (e.g.
telephones, fax machines, analog modems) have a line filter connected between them and
the wall socket (unless you are using a Central Splitter or Central Filter installed by a
qualified and licensed electrician), and to ensure that all line filters are correctly installed and
the right way around. Missing line filters or line filters installed being the wrong way around
can cause problems with your ADSL connection, which includes frequent disconnections.

Installation
15
You can configure the BEC 7300N router through the convenient and user-friendly interface
of a web browser. Most popular operating systems such as Linux and Windows
98/NT/2000/XP/Me include a web browser as a standard application.
3.1 Before Configuration
PCs must have a properly installed Ethernet interface which connects to the router directly
or through an external repeater hub. In addition, PCs must have TCP/IP installed and
configured to obtain an IP address through a DHCP server or a fixed IP address that must be
in the same subnet as the router. The default IP address of the router is 192.168.1.1 and the
subnet mask is 255.255.255.0 (i.e. any attached PC must be in the same subnet, and have
an IP address in the range between 192.168.1.1 and 192.168.1.253). The easiest way is to
configure the PC is to obtain an IP address automatically from the router using DHCP. If you
encounter any problems accessing the router’s web interface you are advised to uninstall
any kind of software firewall on your PCs, as they can cause problems when trying to access
the 192.168.1.1 IP address of the router.
Please follow the steps below for installation on your PC’s network environment. First of all,
check your PC’s network components. The TCP/IP protocol stack and Ethernet network
adapter must be installed. If not, please refer to your Windows-related or other operating
system manuals.

ADSL Mode: There are four modes “Open Annex Type and Follow DSLAM’s
Setting”, ”Annex A”, ”Annex L”, ”Annex M” and “Annex J” that user can select for this
connection.
Modulator: There are seven modes “AUTO”,”ADSL multimode”,”ADSL2”,”ADSL2+”,
“G.Lite:”, “T1.413” and “G.DMT” that user can select for this connection.
72
5.3.3 System
There are five items within the System section: Time Zone, Firmware Upgrade,
Backup/Restore, Restart, User Management and Mail Alert.
73
5.3.3.1 Time Zone
The router does not have a real time clock on board; instead, it uses the Simple Network
Time Protocol (SNTP) to get the current time from an SNTP server outside your network.
Choose your local time zone, click Enable and click the Apply button. After a successful
connection to the Internet, the router retrieves the correct local time from the SNTP server
you have specified. If you prefer to specify an SNTP server other than those in the
drop-down list, simply enter its IP address as shown above. Your ISP may provide an SNTP
server for you to use.
Resync Period (in minutes) is the periodic interval the router waits before it resynchronizes
the router’s time with that of the specified SNTP server. To avoid unnecessarily increasing
the load on your specified SNTP server you should keep the poll interval as high as
possible – at the absolute minimum every few hours or even days.
74
5.3.3.2 Firmware Upgrade
Your router’s “firmware” is the software that allows it to operate and provides all its
functionality. Think of your router as a dedicated computer, and the firmware as the software
it runs. Over time this software may be improved and modified. Your router allows you to
upgrade the software it runs to take advantage of these changes.
Clicking on Browse allows you to select the new firmware image file you have downloaded
to your PC. Once the correct file is selected, click Upgrade to update the firmware in your
router.
Restart Device with: To choose “Factory Default Settings” or “Current Settings” which
uses your current setting on the new firmware (it is highly advised to use Factory Default
Settings over Current Settings for a clean firmware upgrade).
New Firmware Image: Type in the location of the file you wish to upload in this field or
click Browse… to locate it.
Browse…: Click Browse… to find the file with the .afw file extension that you wish to
upload. Remember that you must decompress compressed (.zip) files before you can
upgrade from the file.
Upgrade: Click upgrade to begin the upload process. This process may take up to three
minutes.
Warning
DO NOT power down the router or interrupt the firmware upgrade while it
is still in process. Improper operation may damage the router. Please see
section 2.4 for emergency recovery procedures.
75
5.3.3.3 Backup / Restore
These functions allow you to save and backup your router’s current settings to a file on your
PC, or to restore a previously saved backup. This is useful if you wish to experiment with
different settings, knowing that you have a backup handy in the case of any mistakes. It is
advisable to backup your router’s settings before making any significant changes to your
router’s configuration.
Press Backup to select where on your local PC to save the settings file. You may also
change the name of the file when saving if you wish to keep multiple backups.
Press Browse… to select a file from your PC to restore. You should only restore settings
files that have been generated by the Backup function, and that were created when using
the current version of the router’s firmware. Settings files saved to your PC should not
be manually edited in any way.
Select the settings files you wish to use, and press Restore to load those settings into the
router.
76
5.3.3.4 Restart Router
Click Restart with option Current Settings to reboot your router and save the current
configuration to device.
If you wish to restart the router using the factory default settings (for example, after a
firmware upgrade or if you have saved an incorrect configuration), select Factory Default
Settings to reset to factory default settings.
5.3.3.5 User Management
In order to prevent unauthorized access to your router’s configuration interface, it requires
all users to login with a password. You can set up multiple user accounts, each with their own
password.
You are able to Edit existing users and Add new users who are able to access the device’s
configuration interface. Once you have clicked Edit on the account you want to edit, the
information of the account will be displayed above. Just go ahead and change the password.
You can change the user’s password, whether their account is active and Valid. These
options are the same when creating a user account, with the exception that once created
you cannot change the username. You cannot delete the default admin account; however
you can delete any other created accounts by clicking ticking the box under Delete and then
press the Edit/Delete button.
77
You are strongly advised to change the password on the default “admin” account when you
receive your router, and any time you reset your configuration to Factory Defaults.
5.3.3.6 Mail Alert
Send a log via email, if WAN IP is changed or if intruders accessing your computer without
permission
5.3.4 Firewall
Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet
access from your LAN, as well as helping to prevent attacks from hackers. In addition to this,
when using NAT (Network Address Translation) the router acts as a “natural” Internet firewall,
since all PCs on your LAN use private IP addresses that cannot be directly accessed from
the Internet. See the WAN configuration section for more details on NAT.
78
Firewall: Prevents access from outside your network.
NAT natural firewall: This masks LAN users’ IP addresses, which are invisible to outside
users on the Internet, making it much more difficult for a hacker to target a machine on your
network. This natural firewall is on when the NAT function is enabled.
When using Virtual Servers (port mapping) your PCs are exposed to the
ports specified opened in your firewall packet filter settings.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules
prevent unauthorized computers or applications accessing your local network from the
Internet.
Intrusion Detection: Enable Intrusion Detection to detect, prevent, and log malicious
attacks.
MAC Filter rules: Prevents unauthorized computers accessing the Internet.
URL Filter: Blocks PCs on your local network from unwanted websites.
79
A detailed explanation of each of the following five items appears in the Firewall section
below: Packet Filter, MAC Address Filter, Intrusion detection, Block WAN PING and
URL Filter.
5.3.4.1 Packet Filter
Packet filtering enables you to configure your router to block specified internal/external
users (IP address) from Internet access, or you can disable specific service requests (Port
number) to /from Internet. This configuration program allows you to set up to 6 different filter
rules for different users based on their IP addresses or their network Port number. The
relationship among all filters is “or” operation, which means that the router checks these
different filter rules one by one, starting from the first rule. As long as one of the rules is
satisfied, the specified action will be taken.
80
Rule Name: Users-define description to identify this entry. The maximum name length is
32 characters, and then can choose application that they want from listbox.
Internal IP Address / External IP Address: This is the Address-Filter used to allow or
block traffic to/from particular IP address(es). Input the range you want to filter out. If you
leave empty or 0.0.0.0, it means any IP address.
Protocol: Specify the packet type (TCP, UDP, ICMP, etc.) that the rule applies to.
Select TCP if you wish to search for the connection-based application service on the remote
server using the port number. Or select UDP if you want to search for the connectionless
application service on the remote server using the port number.
Action: If a packet matches this filter rule, Forward (allows the packets to pass) or
Drop (disallow the packets to pass) this packet.
Internal Port: This Port or Port Range defines the ports allowed to be used by the
Remote/WAN to connect to the application. Default is set from range 0 ~ 65535. It is
recommended that this option be configured by an advanced user.
External Port: This is the Port or Port Range that defines the application.
Direction: Determine whether the rule is for outgoing packets or for incoming packets.
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
Log: Choose “log” if you wish to generate logs when the filer rule is applied to a packet.
Add: Click this button to add a new packet filter rule and the added rule will appear at the
bottom table.
Edit: Check the Rule No. you wish to edit, and then click “Edit”.
Delete: Check the Rule No. you wish to delete, and then click “Delete”.
81
Attention
If the DHCP server option is enabled, you must be very careful in assigning
IP addresses of a filtered private IP range to avoid conflicts because you do
not know which PC in the LAN is assigned which IP address. The easiest
and safest way is that the filtered IP address is assigned to a specific PC
that is not allowed to access an outside resource such as the Internet. You
configure the filtered IP address manually for this PC, but it stays in the
same subnet with the router.
5.3.4.2 MAC Filter
A MAC (Media Access Control) address is the unique network hardware identifier for each
PC on your network’s interface (i.e. its Network Interface Card or Ethernet card). Using your
router’s MAC Address Filter function, you can configure to block specific machines from
accessing your LAN.
There are no pre-defined MAC address filter rules; you can add the filter rules to meet your
requirements.
MAC Address: Enter the MAC addresses you wish to manage.
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
82
5.3.4.3 Intrusion Detection
Check Enable if you wish to detect intruders accessing your computer without permission.
The router automatically detects and blocks a DoS (Denial of Service) attack if a user
enables this function. This kind of attack is not to access confidential data on the network;
instead, it aims to disrupt specific equipment or the entire network. If this happens, users will
have trouble accessing the network resources.
Intrusion Detection: Check Enable if you wish to detect intruders accessing your
computer without permission.
Maximum TCP Open Handshaking Count: This is a threshold value to decide whether
a SYN Flood attempt is occurring or not. Default value is 100 TCP SYN per seconds.
Maximum Ping Count: This is a threshold value to decide whether an ICMP Echo Storm
is occurring or not. Default value is 15 ICMP Echo Requests (PING) per second.
Maximum ICMP Count: This is a threshold to decide whether an ICMP flood is occurring
or not. Default value is 100 ICMP packets per seconds except ICMP Echo Requests (PING).
Log: Check Log if you wish to generate logs when the filer rule is applied to the Intrusion
Detection.
83
For SYN Flood, ICMP Echo Storm and ICMP flood, IDS will just warn the user in the Event
Log but it will not be able to protect against such attacks.

5.3.4.4 Block WAN PING
Check Enable if you wish to exclude outside PING requests from reaching this router.
5.3.4.5 URL Filter
URL (Uniform Resource Locator – e.g. an address in the form of http://www.example.com )
filter rules allow you to prevent users on your network from accessing particular websites
from their URL. There are no pre-defined URL filter rules; you can add filter rules to meet
your requirements.
Keywords Filtering: Allows blocking by specific keywords within a particular URL rather
than having to specify a complete URL (e.g. to block any image called “advertisement.gif”).
When enabled, your specified keywords list is checked to see if any keywords are present in
URLs accessed to determine if the connection attempt should be blocked. Note that the URL
85
filter blocks web browser (HTTP) connection attempts using port 80 only.
For example, the URL http://www.abc.com/abcde.html would be dropped since the keyword
“abcde” occurs in the URL.
Domains Filtering: Checks the domain name in URLs accessed against your list of
domains to block or allow. If it matches, the URL request is sent (Trusted) or dropped
(Forbidden). The checking procedure is:
1. Check the domain in the URL to determine if it is in the trusted list. If yes, the connection
attempt is sent to the remote web server.
2. If not, it is checked with the forbidden list. If present, the connection attempt is dropped.
3. If the packet matches neither of the above, it is sent to the remote web server.
4. Please be note that the completed URL, “www” + domain name shall be specified. For
example to block traffic to www.google.com.au, enter “www.google” or
“www.google.com”
Restrict URL Features: This function enhances the restriction to your URL rules.
 Block Java Applet: Blocks Web content which includes the Java Applet to prevent
86
someone who wants to damage your system via the standard HTTP protocol.
 Block ActiveX: Blocks ActiveX
 Block Cookies: Blocks Cookies
 Block Proxy: Blocks Proxy
Except IP Address:
Time Schedule: It is self-defined time period. You may specify a time schedule for your
prioritization policy. For setup and detail, refer to Time Schedule section.
Log: Click “Log” if you wish to generate logs when the filer rule is applied to the URL
Filter.

5.3.5 QoS (Quality of Service)
Quality of Service Introduction
If you’ve ever found your ‘net’ speed has slowed to a crawl because another family member
is using a P2P file sharing program, you’ll understand why the Quality of Service features in
the routers is such a breakthrough for home users and office users.
QoS: Keeping Your Net Connection Fast and Responsive
Configurable by internal IP address, external IP address, protocol, and port, the Quality of
Service (QoS) gives you full control over which types of outgoing data traffic should be given
priority by the router, ensuring bandwidth-consumption data like gaming packets,
latency-sensitive application like voice, or even mission critical files, move through the router
at lightning speed, even under heavy load. You can throttle the speed at which different
types of outgoing data pass through the router. In addition, you can simply change the
priority of different types of upload data and let the router sort out the actual speeds.
QoS Setup
Please choose the QoS in the Configuration item of the left window as depicted below.
After clicking the QoS item, you can Add/Edit/Delete a QoS policy. This page will show the
brief information for policies you have added or edited. This page will also display the total
available (Non-assigned) bandwidth, in percentage, can be assigned.
Application: A name that identifies an existing policy.
88
Direction: The traffic flow direction to be controlled by the QoS policy.
There are two settings to be provided in the Router:
 LAN to WAN: You want to control the traffic flow from the local network to the outside
world. e.g., you have a FTP server inside the local network and you want to have a limited
traffic rate controlled by the QoS policy. So, you need to add a policy with LAN to WAN
direction setting.
 WAN to LAN: Control Traffic flow from the WAN to LAN. The connection maybe either
issued from LAN to WAN or WAN to LAN.)
Protocol: The Protocol will be controlled. For GRE protocol, there is no need to specify
the IP addresses or Application ports in this page. For other protocols, at least one value
shall be given.
 ANY: No protocol type is specified.
 TCP
 UDP
 ICMP
 GRE: For PPTP VPN Connections.
DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS
byte. DSCP Marking allows users to classify traffic based on DSCP value and send packets
to next Router.
Note: To be sure the router(s) in the backbones network have the capability in executing and
checking the DSCP through-out the QoS network.

Rate Type: 2 types are provided:
 Limited (Maximum): specify a limited data rate for this policy. It also is the maximal
rate for this policy. As above FTP server example, you may want to “throttle” the outgoing
FTP speed to 20% of 256K and limit to it, you may use this type.
 Guaranteed (Minimum): specify a minimal data rate for this policy. For example,
you want to provide a guaranteed data rate for your outside customers to access your
internal FTP server with, say at least, 20% of your total bandwidth. You can use this type.
Then, if there is available bandwidth that is not used, it will be given to this policy by following
priority assignment.
Ratio: Assign the data ratio for this policy to be controlled. For examples, we want to only
allow 20% of the total data transfer rate for the LAN-to-WAN direction to be used for FTP
server. Then we can specify here with data ratio = 20. If you have ADSL LINE with
256K/bps.rate, the estimated data rate, in kbps, for this rule is 20%*256*0.9 = 46kbps. (For
0.9 is an estimated factor for the effective data transfer rate for a ADSL LINE from LAN to
WAN. For WAN-to-LAN, it is 0.85 to 0.8).
90
Priority: Specify the priority for the bandwidth that is not used. For examples, you may
specify two different QoS policies for different applications. Both applications need a minimal
bandwidth and need more bandwidth, beside the assigned one, if there is any
available/non-used one available. So, you may specify which application can have higher
priority to acquire the non-used bandwidth.
 High
 Normal: The default is normal priority.
 Low
For the sample priority assignment for different policies, it is served in a First-In-First-Out
way.
Internal IP Address: The IP address values for Local LAN machines you want to control.
(For IP packets from LAN to WAN, it is the source IP address. For IP packages from WAN to
LAN, it is the destination IP address.)
Internal Port: The Application port values for local LAN machines you want to control.
(For TCP/UDP packets from LAN to WAN, it is the source port value. For TCP/UDP packets
from WAN to LAN, it is the destination port value.)
External IP Address: The IP address values for Remote WAN machines you want to
control. (For IP packets from LAN to WAN, it is the destination IP address. For IP packages
from WAN to LAN, it is the source IP address.)
External Ports: The Application port values for remote machines you want to control.
(For TCP/UDP packets from LAN to WAN, it is the destination port value. For TCP/UDP
packets from WAN to LAN, it is the source port value.)
Time Schedule: Scheduling your prioritization policy.

5.3.6 Virtual Server
In TCP and UDP networks a port is a 16-bit number used to identify which application
program (usually a server) incoming connections should be delivered to. Some ports have
numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers
Authority), and these are referred to as “well-known ports”. Servers follow the well-known
port assignments so clients can locate them.
If you wish to run a server on your network that can be accessed from the WAN (i.e. from
other machines on the Internet that are outside your local network), or any application that
can accept incoming connections (e.g. Peer-to-peer/P2P software such as instant
messaging applications and P2P file-sharing applications) and are using NAT (Network
Address Translation), then you need to configure your router to forward these incoming
connection attempts using specific ports to the PC on your network running the application.
You also need to use port forwarding if you wish to host an online game server.
The reason is that when using NAT, your publicly accessible IP address is used by and
points to your router, which needs to deliver all traffic to the private IP addresses used by
your PCs. Please see the WAN configuration section of this manual for information on NAT.
The Internet Assigned Numbers Authority (IANA) is the central coordinator for the
assignment of unique parameter values for Internet protocols. Port numbers range from 0 to
65535, but only port numbers 0 to 1023 are reserved for privileged services and are
designated as “well-known ports”. The registered ports are numbered from 1024 through
49151. The remaining ports, referred to as dynamic ports, or private ports, are numbered
from 49152 through 65535.
94
Examples of well-known and registered port numbers are shown below, for further
information, please see IANA’s website at: http://www.iana.org/assignments/port-numbers

5.3.6.1 Port Mapping
Application: Select the service you wish to configure
Protocol: Automatic when you choose Application from listbox or select a protocol type
which you want.
External Port & Internal Port: Enter the public port number & range you wish to
configure.
Internal IP Address: Enter the IP address of a specific internal server to which requests
from the specified port is forwarded.
Add: Click to add a new virtual server rule. Click again and the next figure appears.
Edit: Check the Rule No. you wish to edit and then click “Edit/Delete”.
Delete: Check the Rule No. you wish to delete, then click “Edit/Delete”.
Since NAT acts as a “natural” Internet firewall, your router protects your network from access
by outside users, as all incoming connection attempts point to your router unless you
specifically create Virtual Server entries to forward those ports to a PC on your network.
When your router needs to allow outside users to access internal servers, e.g. a web server,
FTP server, Email server or game server, the router can act as a “virtual server”. You can set
up a local server with a specific port number for the service to use, e.g. web/HTTP (port 80),
FTP (port 21), Telnet (port 23), SMTP (port 25), or POP3 (port 110). When an incoming
access request to the router for a specified port is received, it is forwarded to the
corresponding internal server.
For example, if you set the port number 80 (Web/HTTP) to be mapped to the IP Address
192.168.1.2, then all incoming HTTP requests from outside users are forwarded to the local
server (PC) with the IP address of 192.168.1.2. If the port is not listed as a predefined
application, you need to add it manually.
96
In addition to specifying the port number used, you also need to specify the protocol used.
The protocol is determined by the particular application. Most applications use TCP or UDP,
however you can specify other protocols using the drop-down Protocol menu. Setting the
protocol to “all” causes all incoming connection attempts using all protocols on all port
numbers to be forwarded to the specified IP address.
5.3.6.2 DMZ
DMZ: The DMZ Host is a local computer exposed to the Internet. When setting a particular
internal IP address as the DMZ Host, all incoming packets are checked by the Firewall and
NAT algorithms, it is then passed to the DMZ host when a packet received does not use a
port number in use by any other Virtual Server entries.
97
Using port mapping does have security implications, since outside users
are able to connect to PCs on your network. For this reason you are
advised to use specific Virtual Server entries just for the ports your
application requires instead of simply using DMZ or creating a Virtual
Server entry for “All” protocols, as doing so results in all connection
attempts to your public IP address accessing the specified PC.
Attention
1. If you disable the NAT option in the WAN-ISP section, the Virtual
Server function becomes invalid.
2. If the DHCP server option is enabled, you have to be very careful in
assigning the IP addresses of the virtual servers in order to avoid
conflicts. The easiest way of configuring Virtual Servers is to manually
assign a static IP address to each virtual server PC, with an address
that does not fall into the range of IP addresses that are issued by the
DHCP server. You can configure the virtual server IP address
manually, but it must still be in the same subnet as the router.
5.3.7 Time Schedule
The Time Schedule supports up to 16 time slots which helps you to manage your Internet
connection. In each time profile, you may schedule specific day(s) i.e. Monday through
Sunday to restrict or allowing the usage of the Internet by users or applications.
This Time Schedule correlates closely with router’s time, since router does not have a real
time clock on board; it uses the Simple Network Time Protocol (SNTP) to get the current
time from an SNTP server from the Internet. Refer to Time Zone for details. You router time
should correspond with your local time. If the time is not set correctly, your Time Schedule
will not function properly.
98
Name: A user-define description to identify this time portfolio.
Day in a week: The default is set from Sunday through Saturday. You may specify the
days for the schedule to be applied.
Start Time: The default is set at 8:00 AM. You may specify the start time of the schedule.
End Time: The default is set at 18:00 (6:00PM). You may specify the end time of the
schedule. Select the Apply button to apply your changes.
99
5.3.8 Advanced
Configuration options within the Advanced section are for users who wish to take
advantage of the more advanced features of the router. Users who do not understand the
features should not attempt to reconfigure their router, unless advised to do so by support
staff.
There are seven items within the Advanced section: Static Route, Dynamic DNS, VLAN,
Device Management, IGMP, SNMP Access Control and Remote Access.
100
5.3.8.1 Static Route
Destination: The destination subnet IP address.
Netmask: Subnet mask of the destination IP addresses based on above destination.
Gateway: The gateway IP address to which packets are forwarded.
Interface: Select the interface through which packets are forwarded.
Cost: Represents the cost of transmission for routing purposes. The number need not be
precise, but it must be between 0 and 65535.
5.3.8.2 Dynamic DNS
The Dynamic DNS function lets you alias a dynamic IP address to a static hostname, so if
your ISP does not assign you a static IP address you can still use a domain name. This is
especially useful for hosting servers via your ADSL connection, so that anyone wishing to
connect to you may use your domain name, rather than having to use your dynamic IP
address, which changes from time to time. This dynamic IP address is the WAN IP address
of the router, which is assigned to you by your ISP.
You first need to register and establish an account with the Dynamic DNS provider using
their website, for example
http://www.dyndns.org/
101
Disable: Check to disable the Dynamic DNS function.
Enable: Check to enable the Dynamic DNS function. The fields following are activated
and required.
Dynamic DNS Server: Select the DDNS service you have established an account with.
Wildcard: Select this check box to enable the DYNDNS Wildcard.
Domain Name, Username and Password: Enter your registered domain name and
your username and password for this service.
Period: Set the time period between updates, for the Router to exchange information
with the DDNS server. In addition to updating periodically as per your settings, the router will
perform an update when your dynamic IP address changes.
5.3.8.3 VLAN
VLAN (Virtual Local Area Network) is a group of devices on different physical LAN segments
that can communicate with each other as if they were all on the same physical LAN
segment.
102
5.3.8.4 Device Management
The Device Management advanced configuration settings allow you to control your router’s
security options and device monitoring features.
Embedded Web Server:
HTTP Port: The port number of the router’s embedded web server (for web-based
configuration uses. The default value is the standard HTTP port, 80. You may specify an
alternative if, for example, you are running a web server on a PC within your LAN.
For Example: User A changes HTTP port number to 100, specifies their own IP address of
192.168.1.55, and sets the logout time to be 100 minutes. The router only allows User A
access from the IP address 192.168.1.55 to logon to the Web GUI by typing:
http://192.168.1.1:100 in their web browser. After 100 minutes, the device automatically
logs out User A.
Universal Plug and Play (UPnP):
UPnP offers peer-to-peer network connectivity for PCs and other network devices, along
with control and data transfer between devices. UPnP offers many advantages for users
running NAT routers through UPnP NAT Traversal, and on supported systems makes tasks
such as port forwarding much easier by letting the application control the required settings,
removing the need for the user to control advanced configuration of their device.
Both the user’s Operating System and the relevant application must support UPnP in
addition to the router. Windows XP and Windows Me natively support UPnP (when the
component is installed), and Windows 98 users may install the Internet Connection Sharing
client from Windows XP in order to support UPnP. Windows 2000 does not support UPnP.
Disable: Check to disable the router’s UPnP functionality.
Enable: Check to enable the router’s UPnP functionality.
UPnP Port: The Default setting is 2800. It is highly recommended you use this port value.
103
If this value conflicts with other ports already in use you may wish to change the port.

5.3.8.5 IGMP
IGMP, known as Internet Group Management Protocol, is used to management hosts from
multicast group.
IGMP Proxy: Accepting multicast packet. Default is set to Disable.
IGMP Snooping: Allowing switched Ethernet / Wireless to check and make correct
forwarding decisions. Default is set to Disable.
5.3.8.6 SNMP Access Control
Software on a PC within the LAN is required in order to utilize this function – Simple Network
Management Protocol.
SNMP V1 and V2:
Read Community: Specify a name to be identified as the Read Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, user obtains this IP address will be able
to view the data.
110
Write Community: Specify a name to be identified as the Write Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, users from this IP address will be able to
view and modify the data.
Trap Community: Specify a name to be identified as the Trap Community, and an IP
address. This community string will be checked against the string entered in the
configuration file. Once the string name is matched, users from this IP address will be sent
SNMP Traps.
SNMP V3:
Specify a name and password for authentication. And define the access right from identified
IP address. Once the authentication has succeeded, users from this IP address will be able
to view and modify the data.
SNMP Version: SNMPV2c and SNMPv3
SNMPv2c is the combination of the enhanced protocol features of SNMPv2 without the
SNMPv2 security. The "c" comes from the fact that SNMPv2c uses the SNMPv1 community
string paradigm for "security", but is widely accepted as the SNMPv2 standard.
SNMPv3 is a strong authentication mechanism, authorization with fine granularity for remote
monitoring.
Traps supported: Cold Start, Authentication Failure.
