? Chapter 1 Introduction
Thank you for purchasing Broadband Router.
This chapter covers a brief descr iption of Broadband Router ’s features, package
content, installation requirements, and the organization overview of this User’ s
Manual.
1.1 The Broadband Router
The Broadband Router is an ideal Broadband (Small Office and Home Office) Router
for sharing single Internet connection with multiple users, providing firewall security,
and access at high speed. Broadband Router offers simple operation and easy setup. It
also provides networking professionals with advanced features like DMZ, Virtual
Server (Port Forwarding), Service Filtering, URL Filtering, and Dynamic DNS etc.
Broadband Router will help you securely connect multiple PCs to the Internet via a
broadband Cable or xDSL modem and becomes your best partner for your network
needs.
1.2 Physical Featu res of Broadband Router
• Auto-Sensing Ethernet Switch
Broadband Router is equipped with a 4-port switch featuring auto-detect
10/100Mbps and auto-crossover. You can use either a Straight-Through or a
Crossover cable to connect your client PC to the LAN port of Broadband
Router.
• 10 / 100 Mbps Ethernet WAN
The 10 / 100 Mbps Ethernet WAN port is connect s to the Internet via a Cable or
xDSL modem.
• Reload Button
You can use the hardware Reload button to restore the factory default settings
into Broadband Router.
1.3 Non-Physical Features of Broadband Router
• Network Address Translation (NAT)/IP Sharing
Broadband Router can translate the source IP address of a LAN client to the IP
address of a WAN client before forwarding a packet from the LAN to the WAN.
When the packet returns, NAT translates the destination address from a WAN
5
client to the address of a LAN client before forwarding the packet back to the
LAN client. When only one WAN IP address is available, NAT can translate the
single WAN IP address into multiple LAN IP addresses for the LAN clients.
Therefore the LAN clients “share” the a single WAN IP address, and this is
called IP Sharing.
• Firewall
Broadband Router provides protection against Ping and TCP/UDP Echo Attack,
Hacker’ s Scan, and Denial of Service (DoS). Also it offers Service Filter and
URL Filter (by Keyword).
• Dynamic DNS
Dynamic DNS (Domain Name System) allows you to register and obtain a fixed
domain name from DDNS service providers that Broadband Router supports.
When your Broadband Router obtains a dynamic public IP address, it will
inform the DDNS service provider with an updated IP address. Any connection
toward your domain name will be mapped to the updated IP address by your
DDNS service provider. You can be found easily by connecting to your fixed
domain name.
• Virtual Server (Port Forwarding)
Broadband Router can forward the service packet specified with a port number
to the LAN host specified by the LAN IP address. In other words, Broadband
Router can open the port for the service with specified port number and then
“ forward” the port to a LAN host. Thus it is called Port Forwarding , too.
• VPN Pass-Through
In a Virtual Private Network, Broadband Router supports the tunneling of
Point-to-Point Tunneling Protocol (PPTP) packet and allows it to enter the LAN
that is the endpoint of the VPN.
• Special Application
Certain Internet applications use multiple ports, port ranges, dynamically
assigned ports, and special protocols. Broadband Router supports the transparent
pass-through of these special applications, including FTP, ICMP, NetMeeting /
H.323, Real Radio, Quick Time, MSN Messenger, etc. and many popular
Internet Games.
• Public DMZ Host
Public DMZ Host is a device with a public IP address on the LAN side.
Broadband Router provides the tunnel service for data traffic between the Public
DMZ Host and the Internet.
• Local DMZ Host
Local DMZ Host is a device with a private IP address on the LAN side.
6
Broadband Router can forward the traffic initiated from the Internet to the Local
DMZ Host.
• DHCP Client
Broadband Router can work as DHCP client and automatically obtain an IP
address from the Internet Service Provider or a DHCP server on the WAN side.
• DHCP Server
As DHCP server, Broadband Router can automatically assign TCP/IP settings to
each client PC on the LAN side and remember each client’s IP address
corresponding to the client’s MAC address. When Broadband Router assigns
TCP/IP settings in the next time, the LAN client will receive the same LAN IP
address.
• Remote Management
Broadband Router can be configured and managed from the WAN side via a
specific port.
• MAC Clone
Broadband Router allows users to specify the MAC address of the Network
Interface Card if Internet Service Provider has the requirement.
• Web-Based Setup
Broadband Router can be managed through the Web browser in a LAN client
PC connected to Broadband Router or the Internet.
• Web-Based Firmware Update
Broadband Router’ s firmware can be updated easily via the Web Configuration
Tool.
• Reload
Broadband Router can restore the factory default settings via the Web
Configuration Tool.

Figure 5 – 6
27
5.7 Dynamic DNS (Domain Name System)
If Broadband Router acquired its WAN IP address via the DHCP or PPPoE schemes,
its IP address is likely to be different from its previous one after Broadband Router is
rebooted or PPPoE session is re-established. This creates difficulty for some
applications due to dynamic nature of Broadband Router WAN IP address. The
“ Dynamic DNS” feature provides a solution to this problem by automatically
updating its WAN IP address to a DDNS service provider.
Many Internet Service Providers provide a kind of service called Dynamic DNS
service, which allows you to register a fixed domain name. Every time when
Broadband Router gets a new dynamic public IP address, it informs the DDNS service
provider with this new IP address; then any connections toward to your domain name
will be mapped to the updated IP address.
Step 1. Select DDNS service p rovider.
Broadband Router supports two DDNS service providers, www.no-ip.com or
www.dyndns.org. Browse to the DDNS service provider’ s web page and
register a new account there. Your DDNS service provider will provide you
the account ID and password.
28
Step 2. Go through the DDNS settings in Broadband Router’ s DDNS section.
Select one DDNS service provider, and fill in the necessary information
form DDNS service provider such as ID, password, and related settings etc.
If no -ip.com was selected, User Name and Password are mandatory; one or
both of Host Name and Group Name have to be entered.
If dyndns.org was selected, User Name, Password and Host Name are
mandatory; Enable W ildcard, Mail Exchanger and Backup MX are optional.
29
Step 3. Update the IP address. When WAN public IP address changes, Broadband
Router will automatically inform your DDNS service provider the new IP
address, or you can force the IP address update by c licking the Update
button.
The update message will show on the screen. If the Refresh button was
clicked the status will show “ No DDNS update activity” after clicking the
Refresh button.
5.8 DHCP Server
1. DHCP Definition
DHCP is the acronym of Dynamic Host Configuration Protocol. It can automate the
IP Address allocation in the network. When this protocol is activated, a DHCP server
can automatically assign IP addresses to DHCP clients. Also, a DHCP client can
automatically obtain its IP address from the DHCP server.
2. DHCP Server in LAN
By default, Broadband Router works as a DHCP server and automatically assigns IP
addresses to all each client PCs on the LAN side.
A. Auto-Remember
When assigning IP addresses to LAN clients, Broadband Router can remember
30
each LAN client’s IP address corresponding to the client’s MAC address. Thus
the LAN client will receive the same LAN IP address, when Broadband Router
assigns IP addresses in the next time.
B. The Pool Range of Assigned IP Address
When DHCP is enabled, you can assign a group of LAN IP addresses. The
group is called “the pool.” You can enter numbers from 2 to 254 in the blanks.
The maximum capacity is 253 IP addresses. The number behind “Starting”
must be smaller than that behind “Ending”. You can specify the domain name
for the group of LAN IP addresses, which are managed by the DHCP server.
Click the button Apply to make your settings take effect.
C. The DHCP IP Address Lease Time
The DHCP Server can lease IPs on a time bases. If a choice of one day is
selected the IP address leased will be released and renew ed in one day.
3. DHCP Client in LAN
When DHCP is enabled in both Broadband Router and the LAN clients, the LAN PC
client can automatically obtain the IP settings, including IP address, Domain Name,
Subnet Mask, Primary DNS, and Secondary DNS from Broadband Router.
4. Static IP Assign
When DHCP is enabled, the SOH Router can assign fixed IP according to client MAC
address.
31
5. DHCP Client List
When DHCP is enabled, a list of DHCP clients can be seen.
If you want to enable DHCP in your PC, refer to A.1 Enable DHCP in Your PC in
Appendix A: Configure TCP/IP in Your PC.
5.9 Virtual Server (Port Forwarding)
The built-in firewall in Broadband Router blocks the traffic initiated from the Internet
in order to protect your LAN. However, Broadband Router can provide tunnel service
and forward the Internet service packet specified with a port number to the server
specified by a LAN IP address. In other words, Broadband Router can open the port
for the service with specified port number and then “forward” the port to the server
specified by a LAN IP address. This function is called “Virtual Server” or “Port
Forwarding”.

5.10 Firewall
1. DMZ Host Configuration
You can set up your personal computer or network-ready device to be a public
or local DMZ hosts. In general, Internet applications use only one unique port
and can pass through a Broadband Router by enabling Virtual Server. However,
some special applications need to implement multiple ports, port ranges,
dynamically assigned ports, and special protocols. Broadband Router can
support the transparent pass-through of these special applications, such as FTP,
NetMeeting/H.323, MSN Messenger, etc. Enable Local DMZ Host when you
have problems running these applications. Besides, you can activate Public
DMZ Host to set up a server and retrieve the traffic initiated from the Internet.
A. Local DMZ Host
To run the special applications, you can assign a device with a LAN IP address
as Local DMZ Host. Then any service request of application initiated from
the Internet will be forwarded to the dedicated LAN host with the LAN IP
address.
34
For example, when you want to run NetMeeting to communicate with your
friend on the Internet, he /she cannot find your LAN host due to Broadband
Router’ s NAT function. However, after you assign the LAN IP address
192.168.1.2 as the Local DMZ Host, your friend can call Broadband Router ’s
Public IP address 140.112.8.8 and the service request of NetMeeting will be
forwarded to your LAN host with the LAN IP address 192.168.1.2, as
illustrated Then you will be able to communicate with your friend via
NetMeeting. Besides, the other LAN clients behind Broadband Router are
still protected by its firewall, and the traffic initiated from the Internet is
denied to access these LAN clients
To activate Local DMZ Host, please check the Enable item and as sign the
LAN IP address of the LAN host. Then click the button Apply to make your
settings take effect.
B. Public DMZ Host
To set up a server with a Public IP address when two or more public IP addresses
are available, you can assign a device with a Public IP address on the LAN side
as Public DMZ Host. Broadband Router can provide tunneling service for data
traffic between Public DMZ Host and the Internet. As shown in the Figure 6-17,
the Host with the P ublic IP address 140.115.2.5 is assigned as Public DMZ Host.
You can set it up as a server, and the traffic initiated from the Internet will be
forwarded to the Host with the Public IP address 140.115.2.5. Besides, the other
LAN clients behind the Broadband Router are still protected by firewall, and the
traffic initiated from the Internet is denied to access these LAN clients.
35
To enable Public DMZ Host, check Enable below Public DMZ Host and enter
the public IP address of the device you want to assign as the Public DMZ Host.
Then click the button Apply to make your settings take effect.
The server in the Public DMZ is not protected by Broadband Router ’ s
firewall. Please pay attention when you enable Public DMZ.
36
2. Anti PING and TCP/UDP Echo Attack
Broadband Router can prevent Ping and TCP/UDP Echo Attack. To enable Broadband
Router’ s firewall against Ping and TCP/UDP Echo Attack, check Denial of Service
Enable and click the button Apply at the end of page to make your setting take effect.
3. URL Filter
If you want to restrict your LAN clients from accessing certain websites, enter the
keywords of the websites in the box. Broadband Router will examine the packet
information when receiving the packet with port 80 from the WAN. If it finds the
listed keywords, it will drop the packet and LAN clients cannot obtain the information
from the website. Check the URL filter Enable and click the Apply button to make
settings effective.
37
4. Port Filter
Broadband Router’ s Service Filter Firewall controls the LAN client’s access to the
Internet services by specifying the port number of the service in the list.
A. Disable
If checked the LAN client can access to all Internet services.
B. Blocking the following port

blocking port 21. The LAN client cannot access ftp in the Internet.
C. Forwarding the following port only
Checking this item will cause LAN clients to only access services using ports
listed. For example, forwarding port 21.The LAN clients can only access ftp in
the Internet.
Please refer to Appendix B: Common Port Numbers.
38
5. MAC Filter
A. Disable
Checking this item, the LAN client s can access to Internet .

For example, forwarding MAC address 00-e0-29-50-00-22. Only this client can
access Internet.
39
6. IP Filter
A. Disable
Checking this item, the LAN clients can access to Internet. No IP filtering is
enabled.
B. Blocking the following IP
Checking this item allows filtering LAN clients based on their IP address. For
example, IP address 192.168.1.2 = client cannot access Internet.
C. Forwarding the following IP only
Checking this item specifies an IP address that can access to Internet.
For example, forwarding IP address 192.168.1.2 = client can access Internet.

Chapter 6 Troubleshooting
6.1 Troubleshooting
You should be able to use Broadband Router after going through the setup steps. If
you cannot access a website on your client PC, the possible reasons could be as
follows. Please check them in the following sequence.
1. Router’ s Hardware Failure.
2. Failed Connection between Broadband Router and Client PCs.
3. Failed Connection on the Broadband Router’ s WAN Side.
4. DNS (Domain Name System) Failure.
Please refer to the solution for each reason and solve your problem. If the problem
persists, please contact our authorized distributor or dealer for technical support.
1. Router ’s Hardware Failure
Solution:
1. Make sure the Power adapter is securely plugged into a power outlet and
Power LED is on.
2. Failed Connection betwe en Broadband Router and Client PC
Solution:
1. Check if the LAN link/act LED is continuously ON or flashing.
2. Use the ping command to probe the network connection between
Broadband Router and the client PC. For example, the Broadband Router
LAN IP address is 192.168.1.1. Type “Ping 192.168.1.1.” (Broadband
Router’ s default IP address. If it shows “Reply from 192.168.1.1”, the
network connection works. If not, please use another Ethernet Cable to
connect your Client PC to Broadband Router.
41
3. If you can reach your Broadband Router with ping command, verify that
you have disabled the Web Proxy function. For information on disabling
the Web Proxy, please refer to A.2 Disable Web Proxy in Appendix A:
