Chapter 3 Login Via the Web Browser

This section describes how to manage the router via a web browser from the remote end. You can use a web browser such as Microsoft Internet Explorer, or Netscape Navigator. It is best to set your display resolution to 1024 x 768. To change the resolution, go to the Microsoft Windows control panel and click on the Display icon, then change the display settings. Access to the management functions of the USB router from the LAN side is restricted. A unique default user account is assigned with user name Admin with an empty password. User can change the default password later when logging to the device.

3.1IP Address

To log on to the device using a web browser, your workstation and the device should both be on the same network segment. The default IP address is 192.168.1.1. You can modify the IP address of your PC by modifying its TCP/IP properties. Follow the steps below:

STEP 1: Enter the TCP/IP screen and change the IP address to the domain of 192.168.1.x/24.

STEP 2: Click on OK to submit the settings. Restart the computer when requested.

STEP 3: Start your Internet browser with the default IP address 192.168.1.1.

3.2Login Procedure

STEP1: Start your Internet browser.

STEP 2: Type the IP address for the router in the browser???s location field. For example, if the IP address is 192.168.1.1, type http://192.168.1.1

STEP 3: You are prompted to enter your user name and password. The user name is ignored. Type your password, or if the password has not been changed, type the default password. The default password is 12345. The password is case-sensitive.

STEP 4: After successfully logging in, the main menu appears.

4.4WAN Setup

Click on WAN Setup from the menu bar to configure the WAN interface for these services: RFC 1483 Bridged, RFC 1483 Routed, PPPoE, PPPoA, and MER. The following are the common settings to set up these services.

VPI and VCI

LLC Encapsulation: With LLC encapsulation, a link control header is added to the Ethernet packet that identifies the protocol type (Ethernet). This allows multiple protocols to be transmitted over the ATM Virtual Circuit.

VC Multiplexing: With VC Multiplexing, no link control header is needed as the ATM Virtual Circuit is assumed to be carrying a single protocol.

Enable NAPT: NAPT or Network Address Port Translation is explained further in section 5.7. This feature is available for RFC 1483 Routed, PPPoE, PPPoA, and MER.

4.4.1 RFC 1483 Bridged

When using RFC 1483-style bridging, Ethernet frames are bridged over ATM Virtual Circuits. The Ethernet frames are encapsulated using either LLC Encapsulation or VC Multiplexing. With LLC encapsulation, a link control header is added to the Ethernet packet that identifies the protocol type (Ethernet). This allows multiple protocols to be transmitted over the ATM Virtual Circuit. With VC Multiplexing, no link control header is needed as the ATM Virtual Circuit is assumed to be carrying a single protocol. Since the Ethernet packets are bridged, the router???s only responsibility is to pass the Ethernet packets to and from the Internet Service Provider and the local network. The IP addresses of the local network are assigned by the ISP either statically or dynamically.

To set up RFC 1483 Bridged mode, configure the common fields on the top of the page and click on the Add button to add the entry.

4.4.2 RFC 1483 Routed

To set up RFC 1483 Routed mode, configure the common settings on the top of the page, then click on RFC 1483 Routed and configure the specific settings (WAN IP address and WAN subnet mask). Click on the Add button to add the entry.

4.4.3 PPPoE

PPPoE provides session authentication using either Password Authentication Protocol (PAP) or Challenge Handshake Authentication Protocol (CHAP). Session accounting is possible and conservation of bandwidth can be achieved by closing down unused sessions. By utilizing PPP, link and network parameters are easily negotiated between the router and the Internet Service Provider (ISP).

When using PPPoE, the system is assigned an IP address from the ISP as part of establishing the network connection. The system can be configured as a DHCP server for the LAN, and NAT can be used to translate private addresses to public addresses. In this way, computers in the LAN do not have to have their own public IP addresses.

To set up PPPoE, click on PPPoE, configure the common fields on the top of the page and the following fields. At the bottom of the screen, click on the Add button to add the entry. If the PPPoE mode is set to auto, clicking on the MANUAL MODE Enable button will effectively disable auto-mode, and require the user to reconnect a terminated PPPoE session by clicking the MANUAL MODE Trigger button. Subsequently, to return to auto-mode, click on the MANUAL MODE Disable button, which will appear in place of the MANUAL MODE Enable button.

User name/Password: Used for remote customers to login during dialup.

Mode: Direct and Auto. If the mode is set to AUTO, the PPPoE negotiation automatically starts when the system identifies any traffic required to be transferred on the link. When DIRECT is selected, the PPPoE negotiation is started manually using the pppoestart command. The default is AUTO with an idle timeout of 30 minutes.

Idle Timeout: Defines the period of idle time (in minutes) after which the PPPoE link will be terminated. This field is necessary to configure under AUTO mode. After a period of inactivity (equal to the timeout value), the device automatically disconnects the user from the network.

Authentication: Defines the authentication code: PAP and CHAP.

Enable DHCP Server: Enables (if checked) or disables the DHCP server. The DHCP server dynamically allocates network addresses and delivers configuration parameters to hosts.

4.4.4 PPPoA

To set up PPPoA, click on PPPoA, then configure the common fields and the following fields. Click on the Add button to add the entry.

User name and Password: Used for remote customers to login upon dialup. PPPoA is

manually activated by entering startup commands from the page: Advanced>Configure

PPPoA. The Authentication field defines the authentication code: PAP or CHAP.

Authentication: Defines the authentication code (PAP or CHAP).

4.4.5 MER

MAC Encapsulation Routing (MER) enables the ATU-R to route IP addresses on the RFC 1483 bridged link. NAPT function is supported to allow multiple private IP addresses on the LAN to share a public IP address.

To set up MER service, configure the common fields, then enter the IP Address and Subnet Mask under the MER section of the screen. Click on the Add button to add the entry.

4.5LAN IP Address

The default LAN IP address is 192.168.1.1. Click on LAN Setup from the menu bar to configure the LAN IP address. Type the IP address and subnet mask. Click on Apply to submit the settings. When the new IP address is applied, the Web configuration will be interrupted. Use the new IP address to login.

5.3DHCP

The Dynamic Host Configuration Protocol (DHCP) provides a centralized approach to allocating IP addresses. It allows IP addresses to be dynamically assigned on an as needed basis, from a pool of addresses. The DHCP server is enabled by factory default with the default IP address of the eth0 to be 192.168.1.1/24.

To add an entry, click on the Add button, and enter the following parameters. Click Apply to submit the settings.

Interface: eth0/usb0. This configures the interface that will provide the DHCP function. By factory default, the entry for interface eth0 is defined with the gateway address 192.168.1.1. The entry for interface usb0 is defined with the gateway address 192.168.201.1.

Starting IP Address: The first IP address of the address pool in the DHCP server. Note the IP address should be in the same subnet as the router???s LAN IP address.

End IP Address: The last IP address of the address pool in the DHCP server. Note the IP address should be in the same subnet as the router???s LAN IP address.

Gateway: The gateway IP address.

Netmask: The subnet mask of the IP network.

DNS: The IP address of the Domain Name Server.

???Information about the following: PPP Authentication, PPP Negotiation, PPPoE Events, IPCP Configuration, TCP/IP Configuration.

The logging record can be accessed from a Telnet or FTP session. Both methods are discussed below.

9.1Log Record from Telnet

To access the logging record from Telnet, complete the following steps.

1. Click on the Windows Start button, then click on Run on the windows start menu.

2. Enter the command telnet followed by the IP address of your router. If the default LAN IP address was not changed, use the IP address 192.168.1.1. (Note: the PC and router must be on the same subnet.)

Log Record From FTP

The following steps describe how to load the log file from FTP.

STEP 1: Connect the router to a PC using the LAN port. Set the PC to the same subnet as the router (the default router address is 192.168.1.1).

STEP 2: Start a Windows command prompt and enter the directory where you want to load the file.

STEP 3: At the prompt, type ftp followed by a space and the router???s IP address.

STEP 4: A welcome message appears. At the user prompt, type root (lowercase).

STEP 5: At the Password prompt, press the Enter key (there is no password to type).

STEP 6: After you see the message User logged in, type: bin

STEP 7: After you see the message Type set to I, type: ha

STEP 8: After you see the message Hash Mark Printing On ftp, type: get logfile <filename.txt>

Example: get logfile adsl.ext

The message Transfer complete appears when the file is loaded.

STEP 9: Open the file from the directory where it is loaded.

A sample file is shown below. The first line shows an incoming packet, the subsequent lines show information about the packet. To better understand information in the packet, refer to RFC 2516 and RFC 1661.
