Chapter 3 Web User Interface
This section describes how to access the device via the web user interface using
an Internet browser such as Microsoft Internet Explorer (version 5.0 and later).
3.1 Default Settings
The following are the default settings for the device.
•
•
•
•
•
•
•
•
•
•
•
•
•
Local (LAN) access (username: root , password: 12345)
Remote (WAN) access (username: support, password: support)
User access (username: user, password: user)
LAN IP address: 192.168.1.1
WAN IP address: none
Remote WAN access: disabled
DHCP server: enabled in routing modes (PPPoA/E, IPoA & MER)
Firewall and NAT: enabled for PPPoE and PPPoA
disabled for Bridge*, MER and IPoA
* NAT is not available in Bridge mode
This device supports the following connection types.
PPP over Ethernet (PPPoE)
PPP over ATM (PPPoA)
MAC Encapsulated Routing (MER)
IP over ATM (IPoA)
Bridging
Technical Note:
During power on, the device initializes all settings to default values. It will then
read the configuration profile from the permanent storage section of flash
memory. The default attributes are overwritten when identical attributes with
different values are configured. The configuration profile in permanent storage
can be created via the web user interface or telnet user interface, or other
management protocols. The factory default configuration can be restored either
by pushing the reset button for more than five seconds until the power indicates
LED blinking or by clicking the Restore Default Configuration option in the Restore
Settings screen.
3.2 IP Configuration
DHCP Mode
When the device powers up, the DHCP server (on the device) will start
automatically. To set your PC for DHCP mode, check the Internet Protocol
properties of your Local Area Connection. You can set your PC to DHCP mode by
selecting Obtain an IP address automatically in the dialog box shown below.
15

STATIC IP Mode
To configure the device manually, your PC must have a static IP address within
the 192.168.1.x subnet. Follow the steps below to configure your PC IP address
to use subnet 192.168.1.x. The following assumes you are running Windows XP.
STEP 1: From the Network Connections window, open Local Area Connection
(You may also access this screen by double-clicking the Local Area
Connection icon on your taskbar). Click the Properties button.
16

STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.
The screen should now display as below. Change the IP address to the
domain of 192.168.1.x (1<x<254) with subnet mask of 255.255.255.0.
STEP 3: Click OK to submit the settings.
3.3 Login Procedure
Perform the following steps to login to the web user interface.
NOTE: The default settings can be found in 3.1 Default Settings.
STEP 1: Start the Internet browser and enter the default IP address for the
device in the Web address field. For example, if the default IP address
is 192.168.1.1, type http://192.168.1.1.
NOTE: For local administration (i.e. LAN access), the PC running the browser
must be attached to the Ethernet, and not necessarily to the device.
For remote access (i.e. WAN), use the IP address shown on the Device
Info - WAN screen and login with remote username and password.
STEP 2: A dialog box will appear, such as the one below. Enter a default
username and password, as defined in section 3.1 Default Settings.
17

Click OK to continue.
NOTE: The login password can be changed later (see 8.4.3 Passwords)
STEP 3: After successfully logging in for the first time, you will reach this screen.
NOTE1: If a PVC connection already exists then this Quick Setup screen will be
bypassed and the Device Info – Summary screen will display instead.
NOTE2: The selections available on the main menu (onscreen at left) are based
upon the configured connection and user account privileges.

Chapter 4 Quick Setup
After login, the Quick Setup screen will appear as shown.
The Quick Setup screen allows the user to configure the ADSL router for DSL
connectivity and Internet access. It also guides the user through the WAN
network setup first and then the LAN interface setup. You can either manually
customize the router or follow the online instructions to set up the router.
The following configuration considerations apply:
•
•
•
•
•
The WAN network operating mode operation depends on the service provider’s
configuration in the Central Office and Broadband Access Server for the PVC
If the service provider provides PPPoE service, then the connection selection
depends on whether the LAN-side device (typically a PC) is running a PPPoE
client or whether the router is to run the PPPoE client. The router can support
both cases simultaneously.
If some or none of the LAN-side devices do not run PPPoE client, then select
PPPoE. If every LAN-side device is running a PPPoE client, then select Bridge.
In PPPoE mode, the router also supports pass-through PPPoE sessions from
the LAN side while simultaneously running a PPPoE client fro non-PPPoE LAN
devices.
NAT and Firewall are always enabled in PPPoE or PPPoA modes, optional for
MER or IPoA modes, and always disabled in Bridge mode.
Depending on the network-operating mode and NAT and firewall status, the
main panel will display or hide the NAT/Firewall menu. For instance, at initial
setup, the default network-operating mode is Bridge. The main panel will not
show the NAT and Firewall menu.
NOTE: Up to 8 PVC profiles can be configured and saved. To activate a
particular PVC profile, you need to navigate through all the setup
screens, click the Save button and reboot the system.
