Overview of the Broadband Router
The Broadband Router is a small desktop router that sits between your local Ethernet
network and a remote network (e.g., the Internet or a remote office). The Broadband
Router contains an EWAN port connecting to Internet via external ADSL/Cable
modem , a COM port worked as a managemant Console , and a one-port 10/100
Ethernet switch. Data comes into the Broadband Router from the local LAN and then
is “routed” to the remote network. In addition to its capability to route IP/IPX traffic,
the Broadband Router also acts as a bridge for other network protocols, such as
Appletalk or SNA.
Broadband Router Applications
The main functions of the Broadband Router
-to allow devices on your LAN to access the Internet,
-to access servers from the public network,
-to create Virtual Private Network (VPN).
Accessing the Internet
The most common use for the Broadband Router is to provide Internet access, so that
everyone on your LAN can surf the web and send/receive email or files.
1-2
The Broadband Router automatically acquires the necessary IP address when the
connection to the Internet is established. You don’t need to apply for and assign an IP
address to each PC or workstation on your network.
ivate wide area network with Broadband Router via external ISDN TA/modem and
provide Internet access for everyone on your LAN to surf the web and send/receive email or files simultaneously
Figure 1-1 Internet Access
Accessing Servers from the Public Network
If you want special servers to be accessible by remote users across the Internet (e.g.,
an e-mail server, an FTP server, or a web server), you can configure the Broadband
Router to proxy the service from its own address. This means that the remote user can
address the router as if it were the special server and the Broadband Router will redirect this connection to the appropriate computer on the network.
Creating a Virtual Private Network (VPN)
Virtual Private Networking (VPN) provides a means to connect remote LANs over
the Internet, while only local toll charges to an Internet Service Provider are incurred
even if the two LANs are physically remote to each other.
To create a VPN between two sites, a special connection called “tunnel” followed by
a VPN data session has to be set up over the Internet. After a VPN data session is set
up, data can be sent over it, optionally encrypted to prevent unauthorized access.
Additionally, VPN tunnels allow IP, IPX and Bridging traffic to flow across the
Internet, including NetBIOS information (for Windows networking) encapsulated
within IP or IPX packets.
All information required for a VPN is defined in a VPN profile, which contains, for
example, the IP address of the VPN partner and authentication information (including
the encryption key that is used).
When a PC from one site tries to communicate with a device on the other site for the
1-3
first time, the VPN tunnel and data session establishment process will be triggered
automatically. For the originating side, first the destination IP address will be used to
search for the corresponding VPN profile. Based on the information conifgured in the
matched VPN profile, a VPN tunnel is created, a VPN data session will be created
and authentication information exchanged, then data traffic can start to flow. For the
destination side, when a VPN data session creation is requested, the router will base
on the originating IP address to search for a matched profile. Once found, the
Broadband Router will use the information in the matched profile to authenticate the
incoming "call", after which data transfer can begin.
More than one VPN data sessions can be established over the same tunnel.
See chapter 4 for detailed configuration instructions.
Figure 1-2 Creating a Virtual Private Network
A Configuration Example
In Figure 1-3, two Broadband Routers are installed in two different locations. They
are connected to the Internet via ADSL/Cable modem, allowing users to surf the
Web. They are also connected to each other through the telephone network, forming a
private company network.
Figure 1-3 Connecting Two Private Networks
This example also illustrates an important feature of the Broadband Router that a
private device can be accessed from the Internet by mapping the application port
number to a port number on the Broadband Router. In this case, an Internet user
references the URL http://206.112.113.6, which was assigned to the Broadband
1-4
Router by the ISP, and the Broadband Router will translate that address to
192.168.168.112, port 80.
All devices on both LANs (except for the Web servers) are configured to obtain their
IP addresses automatically (i.e., from the built-in DHCP server in the Broadband
Router). Since the Web Server on LAN #1 must have the same address all the time,
this machine has a statically configured DHCP address. These IP addresses are only
used in the local LAN environment, these devices naturally form a private network
(with default IP network address of 192.168.168.0) and are not accessible by users
across the Internet (if they are not mapped). In Broadband Router, it is possible to
assign public IP addresses obtained from your ISP and they will be accessible by
users across the Internet. These public addresses can co-exist in the same LAN
private address segment.
In order to let the LAN to LAN communications work, the default private network
address (192.168.168.0) for one of the above Broadband Router has to be changed
(to 192.168.170.0 in the above example). The traffic between these two networks is
secure because data are sent across the telephone network via a direct phone call.
A Security Overview
More and more people are concerned about security of their data in the Internet
The Broadband Router provides many ways to help make your network and your
data secure:
• All dial-in users and LAN-to-LAN communications require PPP PAP/CHAP/
MS-CHAP authentication (basically user name and password)
• The Broadband Router also supports call-back for dial-in users - so that remote
user are really who they say they are
• The Broadband Router uses a private IP addressing scheme to prevent devices on
your LAN from access by outside users
• Console, Telnet and ARM support password protection
• DES encryption with PPP/ECP negotiation is supported for VPN connections
• IP packet filtering may be used to futher enhance security requirements

3 Configuring the Broadband Router
Once you have completed the installation stage and have configured a PC properly as
described in chapter two, you are ready to configure the Broadband Router for actual
applications.
This chapter describes how to configure your Broadband Router for basic Internet
access, as well as for the following configurations:
• To set up Internet access with advanced features
• To set the system time
• To configure Internet access time restrictions
Internet Access in Five Minutes
In this section you will be shown how to configure the Broadband Router for basic
Internet access in less than five minutes using the web browser-based Acess Router
Manager (ARM).
Using Different Browsers for Broadband Router
Configuration
To configure your Broadband Router, you can use popular browsers such as
Netscape 4.5 and Internet Explorer 5.x. The following describes, after each browser is
brought up, how to use it to start the ARM interface:
Netscape Navigator 4.5 (or newer):
In the Location box (where you normally enter the URL address), enter the default
private IP address of the Broadband Router followed by hitting the return key:
http://192.168.168.230
Internet Explorer 5.0 (or newer):
In the Address box (where you normally enter the URL address), enter the default
private IP address of the Broadband Router followed by hitting the return key:
http://192.168.168.230
Logging On
After entering the default IP address as described above, a password prompt screen
3-2
will ask you to log on. If you are logging on for the first time, you should accept the
factory default password (which is “password”). The password is always displayed as
a string of asterisks (“*”). Clicking the Log On button will begin a Access Router
Manager (ARM) session. The next time you log in, even if you have modified the
password , the default password (“password”) will still be used as the default. You
need to change it to the correct password before you will be let in.
No matter what password you use, each character will always be displayed in the
logon prompt as a “*”.
If you forget the password, you need to follow steps described in chapter 5 to be able
to log on.
The Broadband Router comes with a basic feature set installed. If you have purchased
additional features from your distributor, you will also be given a “feature key”. In
this case, you will need to click the box below the Log On button that says “Check
here to install additional features” before you click the Log On button.
3-3
Customizing the ARM for Your Specific Needs
When you log on for the first time, the ARM Customization screen will be
automatically displayed, allowing you to customize the ARM session to suit your
own specific needs:
The choices available depend on what feature keys have been installed. The
selections you make determine what configuration menu and buttons will appear in
the ARM interface. For example, if you select Basic Internet Access only, the ARM
interface will display only buttons and screens that you need for basic Internet access.
If you subsequently use ARM to configure the Broadband Router for other
applications, you can return to this ARM Customization screen to “re-customize”
your ARM interface by selecting Customize User Interface from the ARM Menu
(on the left hand side of the ARM interface).
Basic Internet Access
Select this option if you need basic Internet access. This will enable you to configure
Internet Access for all of your LAN users.
Internet Access with Advanced Configuration
Select this option if you want to configure advanced options, such as changing the
private IP address (e.g., when you intend to create your own private WAN among
multiple Broadband Router ), or adding a public IP address (e.g., when you want to
install servers on the LAN which are accessible from the Internet).
Share Netware (IPX) Resource(optional)
Select this option if you use Novell servers on your network and want to allow dial-in
users or remote offices to share them.
Note: The choice displayed in this screen depend on the feature keys which are
installed in your system.
Overview of The ARM Browser Screen
Before you begin the configuration, take a moment to look at the ARM screen. Look
for these areas:
3-4
• ARM Menu
• Configuration Window
• Message Window
• Status Window
ARM Menu
This part of the browser screen contains items you can click to display the various
screens for configuring your Broadband Router, including EWAN, connection
profiles, and protocols, as well as system monitoring, tools, and help.

What is a Connection Profile?
To access the Internet, you need to apply for an account with an ISP (Internet Service
Provider), who will provide you the ISP Account name and ISP Account Password
that you need to call, as well as phone number if necessary to dial-up to your ISP.
You need to enter such information into a “connection profile” in the Broadband
Router. Likewise, a connection profile needs to be created for each dial-in user, each
remote office, or each VPN user.
Essentially, a connection profile contains all information that the Broadband Router
needs to access the Internet, or support a remote dial-in user, or set up a connection
with a remote office, or create a VPN. Such information includes dial-up phone
numbers, authentication information (the local user name and password and possibly
the remote site user name password), plus other information that may be required for
the communication.
Selecting Internet Access Interface
Select EWAN port to connect ADSL/Cable Modem.
The following screen show you the interface configuration ,please select EWAN to
be your interface from the Broadband Router.
Configuring a Basic Internet Access Profile (via
EWAN)
To configure an Internet access connection profile, from the ARM menu, press
Connection Profiles. If there are no other profiles at this point, you will immediately
enter a profile configuration screen. First decide what interface to use for Internet
access.
Step 1
Note: The ARM Customization screen is displayed the very first time you invoke
the ARM tool. To return to this screen, select Customize User Interface from the
ARM Menu.
3-7
Enter the following information:
Profile Name: the name that you will use to identify this Internet access
profile.
Obtain IP Addresses Automatically: Please specify IP address ,
netmask,gateway and domain name server assigned by ISP.
EWAN IP Address: the IP address of your EWAN.
EWAN IP Netmask: the IP Netmask of your EWAN.
ISP Gateway IP Address: the IP address of your ISP Gateway
Primary DNS IP Address: the IP address of primary domain name server
Secondary DNS IP Address: the IP address of secondary domain name
server
Note: After configuring each item, please go to step 4.
Step 2 If you choose “via DHCP” the following items will appear.
Please enter the following information:
Profile Name: the name that you will use to identify this Internet access
profile.
Obtain IP Addresses Automatically: get the IP address via DHCP
3-8
(Optional) Host Name (System Name): the Host Name provided by your
system.
Note: After configuring each item, please go to step 4.
Step 3 If you choose “via PPP over Ethernet” the following items will appear.
Please enter the following information:
Profile Name: the name that you will use to identify this Internet access
profile.
Obtain IP Addresses Automatically: Some DSL-based ISPs use PPPoE
to establish communication with end-users.
ISP Account Name: the username of your ISP account
ISP Account Password: the password of your ISP account
(Optional) Service Name: the Service Name provided by your ISP, if one
is required, otherwise, leave it empty
(Optional) Access Concentrator Name: the Access Concentrator Name
provided by your ISP, if one is required, otherwise, leave it empty
Idle Timeout(0-3600 seconds): The default value of the idle timeout is
120 seconds. It represents the number of seconds of inactivity over the
connection: when this value is reached, the Broadband Router will
disconnect the call. You can change the idle timeout value to anything
between 0 to 3600 seconds. But if you select 0, the connection will never
time out.
(Optional) Host Name (System Name): the Host Name provided by your
system.
Note: After configuring each item, please go to step 4.
Step 4 Click APPLY or APPLY and Test
3-9
Note: When you click Apply or Apply and Test , the Broadband Router connects
to your Internet Service Provider. Watch the Message Window for any messages. If
the test is successful, your users will be ready to access the Internet. If not, the
Broadband Router will try to give you enough information to let you know why the
connection is not successful.
If Apply or Apply and Test is successful, users on your LAN can now start to
access the Internet. However, it is required that these devices have also been
configured to obtain IP addresses automatically, as described in Chapter 2. Users may
need to re-boot their computers in order to obtain the DNS information obtained
dSetting Up Internet Access with Advanced Features
When you check the box, Internet Access with Advanced Configuration on the
ARM Customization Screen, additional configuration choices become available
during your ARM configuration session. For example, some of these choices will
allow you to , modify the Broadband Router private IP address, and/or assign a
public IP address.
Note: After you change the private IP address of a Broadband Router , all devices
on your LAN will no longer be able to communicate with it. You need to reboot all
devices in order for them to be able to communicate with the Broadband Router
again. (Rebooting each device will cause them to acquire a new private IP address
and default Gateway within the re-configured network from the Broadband Router).
In order for the Broadband Router to support public servers for access by the
Internet, you need to create a “public” network on your LAN. This can be done in one
of two ways. Use Network Address Translation to map the application to be accessed
from the Internet. This procedure is described in the section “Port Address
Translation” in Chapter 5, or acquire public IP addresses., from your ISP and assign it
to the router and to the public devices on your LAN. The procedure to assign a public
IP address to the router is described below.
Note: The ARM Customization screen displays the very first time you invoke the
ARM tool. To return to this screen, select Customize User Interface from the ARM
Menu.
Modifying Public and Private IP Addresses
You can use the IP screen to enter a public IP address, modify a private IP address,
modify or enter DNS addresses configure WINS addresses and node type or enable or
disable the DHCP service.
Step 1 Select IP from the ARM menu:
Configuration - Advanced IP
3-10
Then the following screen displays:
Step 2 Enter the following information:
Note: To install publicly addressed servers on your network (e.g., Web or ftp
servers), you need to apply for an IP address for each server plus one for the LAN
port of the Broadband Router. All these public IP addresses have to belong to the
same IP network.
Public IP Address: the public IP address for the LAN interface on the
Broadband Router.
Public IP Netmask: the network mask for the public network address on
your LAN.
Private IP Address: the private IP address for the LAN interface on the
Broadband Router. The default private IP address is 192.168.168.230. If
you want to create your own private network through other Broadband
Router at remote office locations, you need to make sure that each
Broadband Router on each LAN is assigned an address in a unique private
IP network .
Note: Once you change the private IP address (e.g., from the default of
192.168.168.230 to 192.168.167.230) either from the browser or through a telnet
session (which is based on the IP address), you will no longer be able to
communicate with your Broadband Router. To reconnect, you need to re-boot

your computer. This is so that your device will re-acquire the IP address and
default Gateway from the Broadband Router based on the new private IP
network. Your device will then again be able to communicate with your
Broadband Router. For the same reason, all devices on the LAN need to be
restarted before they can access the Internet again.
Private IP Netmask: the network mask for your private network. Its
value is 255.255.255.0 and cannot be changed.
The Broadband Router private address of 192.168.xxx.yyy is called a
“Class C” IP address. This means that changing xxx will change the
network while changing yyy will assign a different address in the same
network.
Primary DNS IP Address: the IP address of the primary Domain Name
Server (DNS). If properly configured, when a computer re-boots and
acquires the IP address from the Broadband Router, the IP addresses of
both the primary and the secondary DNS server will be provided to
requesting client workstations. This field will reflect the DNS addresses
acquired from the ISP and will be used to assign to requesting DHCP
clients (see below). You may change this address if you want another
address to be assigned instead. The Broadband Router will pave any
manually configured DNS addresses.
Secondary DNS IP Address: the IP address of the secondary Domain
Name Server.
Note: When a Broadband Router connects to the ISP, it will automatically be
assigned the IP address of a primary Domain Name Server (DNS), as well as the
IP address for a secondary DNS.
DHCP: this enables or disables the Broadband Router Dynamic Host
Configuration Protocol (DHCP) feature. If you want the Broadband
Router to act as a DHCP server and assign private IP addresses to any
requesting DHCP client, make sure DHCP is enabled (the default). When
enabled, the Broadband Router will provide an IP address, network mask,
gateway address (the Broadband Router private IP address), DNS
addresses WINS server address and windows node type to any
workstations on the local area network that are configured as a DHCP
client.
Note: Devices on your network that are configured with public IP addresses
are not DHCP clients. Therefore, you need to assign their IP addresses, network
mask, default gateway’s IP address, primary and secondary DNS IP addresses
manually.
MAC Address cloning: Some ISPs may require you to register the MAC
address of your card/adapter, please refer to the CLI manual.

Setting the System Time
The Broadband Router maintains a real-time clock which is automatically set to the
local time of the management PC the first time a connection is made to ARM. To
modify the Broadband Router clock, follow the steps below.
The time is used to provide time stamps for Connection Log and System Log entries.
It is also used for determining Internet access restrictions (see the section, “Setting
Internet Access Time Restrictions”, below).
Since the Broadband Router does not contain a backup battery for the real-time clock,
the time will not be maintained across system resets or power cycles. Therefore, after
a reset or power cycle, the clock will not be correct. To set the clock once again,
simply log on to ARM. Note that the time zone and daylight savings time indicator
are saved across power cycles.
Note: The System Time menu choice will not be shown if only Basic Internet
Access was selected in the ARM Configuration screen
To view or change the system time settings, select System Time from the menu:
Configuration - Advanced - System Time
The following screen displays:
Step 1 Select the Time Zone of the router location from the selections in the drop-
down list (if needed).
Step 2 Check the Daylight Savings Time box, if appropriate. Note that the setting
for Daylight Savings Time does not change automatically. Setting the
system time between Standard Time and Daylight Savings Time must be
done manually.
Step 3 Click Apply. The Broadband Router time and Time Zone is now reflected
in the “Current Router Time” box.
Note: The proposed Router Time is always based upon the time set in the
management PC, adjusted for the selected Time Zone.

Setting Internet Access Time Restrictions
For cost, security and efficiency reasons, you may want to adjust the times when the
Broadband Router will be allowed to automatically connect to the Internet. A simple
setup screen is used to enter the days of the week and the hours of the day during
which Internet access is allowed. The Broadband Router will not connect to the
Internet outside of the configured times.
In order for this feature to be effective, the Broadband Router must be configured for
the current local time. To do this, see the section, “Setting the System Time”, above.
Note, however, that if for some reason the Broadband Router is reset or powercycled, the previous time setting will be lost. Until you once again set the time, the
Broadband Router will either allow Internet access or not, depending upon a setting
which is configured below.
To view or change Internet access time restriction settings, select Internet Access
Time from the menu:
Configuration - Internet Access Time
The following screen is displayed:
Step 1 Set the days of the week during which Internet access is allowed. Select
Day Range if you want to specify a range of days. If you select All,
Internet access will be allowed every day.
Step 2 Set the time during which Internet access will be allowed. Not that this
setting is based upon a 24 hour clock. Select Time Range to enter a
consecutive period of time between which Internet access is allowed. If
you select All, Internet access will be allowed from midnight to midnight
on the days selected in Step 1.
Step 3 Enter the default setting for Internet access if the router is power-cycled or
reset. If you enter “Yes” (the default), then Internet access will be allowed
unconditionally until the clock is set. If you enter “No”, then Internet
access will not be allowed until the clock is set.
Step 4 Click Apply to enable your settings.
