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.

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.

4.1 Auto Quick Setup

This function provides an automated process to quickly setup a WAN connection. The device will auto-detect the best PVC profile available, provided that the ADSL link is up. For manual setup, please skip to 4.2 Manual Quick Setup.

STEP 1: Select Quick Setup to display the DSL Quick Setup screen.

STEP 2: Click Next to start the setup process. Follow the onscreen prompts.

STEP 3: After setup is complete the device will reboot.

NOTE: After the device reboots, the Device Info – Summary screen should

appear. If the browser does not refresh automatically, close it and restart. You will need to login again.

If you encounter any difficulties, be sure to check the IP configuration

and configure as appropriate (see section 3.2 IP Configuration)

4.2 Manual Quick Setup

STEP 1: Select Quick Setup from the main menu and uncheck the DSL Auto-

connect checkbox ; to begin the manual quick setup process.

Uncheck to begin the manual quick setup process and display the following screen.

STEP 2: Adjust the VPI/VCI settings for the connection you wish to establish.

Click Next to continue.

STEP 3: On this screen, you can choose the connection type and select the

appropriate encapsulation mode. The available options are shown.

 PPPoA- VC/MUX, LLC/ENCAPSULATION  PPPoE- LLC/SNAP BRIDGING, VC/MUX  MER- LLC/SNAP-BRIDGING, VC/MUX  IPoA- LLC/SNAP-ROUTING, VC MUX  Bridging- LLC/SNAP-BRIDGING, VC/MUX

available for this router.

4.2.1 PPP over ATM (PPPoA) and PPP over Ethernet (PPPoE)

STEP 4: Select PPP over ATM (PPPoA) or PPP over Ethernet (PPPoE) and click

Next. The following screen appears. Enter the Username and

Password and select the connection options you wish. Review the descriptions below for more details. Click Next to continue.

PPP Username/PPP Password

The PPP Username and the PPP password requirement are dependent on the particular requirements of the service provider. A maximum of 256 characters is allowed for the PPP user name and a maximum of 32 characters for PPP password.

PPPoE service name

For PPPoE service, PADI requests contain a service label. Some PPPoE servers (or BRAS) of ISP check this service label to make a connection.

Dial on Demand

The device can be configured to disconnect if there is no activity for a period of time by selecting this check box. When the checkbox is ticked, you must enter the inactivity timeout period. The timeout period ranges from 1 to 4320 minutes.

PPP IP Extension

The PPP IP Extension is a special feature deployed by some service providers. Unless your service provider specifically requires this setup, do not select it.

PPP IP Extension does the following:

•

Allows only one PC on the LAN

•

The public IP address assigned by the remote side using the PPP/IPCP protocol is actually not used on the WAN PPP interface. Instead, it is forwarded to the PC LAN interface through DHCP. Only one PC on the LAN can be connected to the remote, since the DHCP server within the device has only a single IP address to assign to a LAN device.

•

NAT and firewall are disabled when this option is selected.

•

The device becomes the default gateway and DNS server to the PC through DHCP using the LAN interface IP address.

•

The device extends the IP subnet at the remote service provider to the LAN PC. i.e. the PC becomes a host belonging to the same IP subnet.

•

The device bridges the IP packets between WAN and LAN ports, unless the packet is addressed to the device’s LAN IP address.

Use Static IP Address

Unless your service provider specially requires this setup, do not select it. If selected, enter your static IP address in the IP Address field. Also, do not forget to adjust your TCP/IP Settings as described in subsection 3.2 IP

Configuration.

MTU

This option allows us to change the MTU size for WAN interface, PPPoE and PPPoA. The default values are 1492 for PPPoE and 1500 for PPPoA.

STEP 5: This screen allows the user to control IGMP Multicast and WAN Service.

Enable IGMP Multicast checkbox:

Tick the checkbox to enable IGMP multicast (proxy). IGMP (Internet Group Membership Protocol) is a protocol used by IP hosts to report their multicast group memberships to any immediately neighboring multicast routers.

Enable WAN Service checkbox:

Tick this item to enable the ATM service. Untick it to stop the ATM service.

Service Name: This is the WAN Service label.
