Chapter 3 Web User Interface

This section describes how to access the device via the web user interface (WUI)

using an Internet browser such as Internet Explorer (version 5.0 and later).

3.1 Default Settings

The factory default settings of this device are summarized below.

• LAN IP address: 192.168.1.1

• LAN subnet mask: 255.255.255.0

• Administrative access (username: root, password: 12345)

• User access (username: user, password: user)

• Remote (WAN) access (username: support, password: support)

• WLAN access: enabled

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 ten 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 NexusLink 3240 powers up, the onboard DHCP server will switch on.

Basically, the DHCP server issues and reserves IP addresses for LAN devices, such

as your PC.

To obtain an IP address from the DCHP server, follow the steps provided below.

NOTE: The following procedure assumes you are running Windows. However,

the general steps involved are similar for most operating systems (OS).

Check your OS support documentation for further details.

may also access this screen by double-clicking the Local Area Connection

icon on your taskbar). Click the Properties button.

STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.

STEP 3: Select Obtain an IP address automatically as shown below.

STEP 4: Click OK to submit these settings.

If you experience difficulty with DHCP mode, you can try static IP mode instead.

STATIC IP MODE

In static IP mode, you assign IP settings to your PC manually.

Follow these steps to configure your PC IP address to use subnet 192.168.1.x.

NOTE: The following procedure assumes you are running Windows. However,

the general steps involved are similar for most operating systems (OS).

Check your OS support documentation for further details.

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.

STEP 2: Select Internet Protocol (TCP/IP) and click the Properties button.

STEP 3: Change the IP address to the 192.168.1.x (1<x<255) subnet with subnet

mask of 255.255.255.0. The screen should now display as shown below.

STEP 4: Click OK to submit these settings.

3.3 Login Procedure

Perform the following steps to login to the web user interface.

NOTE: The default settings can be found in section 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

Information screen and login with remote username and password.

STEP 2: A dialog box will appear, such as the one below. Enter the 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 section 9.6.1 Accounts).

STEP 3: After successfully logging in for the first time, you will reach this screen.

You can also reach this page by clicking on the following icon located at the top of

the screen.

The following screen appears when Wireless Security is selected. The options shown

here allow you to configure security features of the wireless LAN interface.

Please see 6.13.3 for WPS setup instructions.

Click Apply/Save to implement new configuration settings.

WIRELESS SECURITY

Setup requires that the user configure these settings using the Web User Interface

(see the table below).

Select SSID

Select the wireless network name from the drop-down menu. SSID stands for

Service Set Identifier. All stations must be configured with the correct SSID to

access the WLAN. If the SSID does not match, that client will not be granted access.

Network Authentication

This option specifies whether a network key is used for authentication to the wireless

network. If network authentication is set to Open, then no authentication is

provided. Despite this, the identity of the client is still verified.

Each authentication type has its own settings. For example, selecting 802.1X

authentication will reveal the RADIUS Server IP address, Port and Key fields. WEP

Encryption will also be enabled as shown below.

The settings for WPA2-PSK authentication are shown next.

WEP Encryption

This option specifies whether data sent over the network is encrypted. The same

network key is used for data encryption and network authentication. Four network

keys can be defined although only one can be used at any one time. Use the Current

Network Key list box to select the appropriate network key.

Security options include authentication and encryption services based on the wired

equivalent privacy (WEP) algorithm. WEP is a set of security services used to

protect 802.11 networks from unauthorized access, such as eavesdropping; in this

case, the capture of wireless network traffic.

When data encryption is enabled, secret shared encryption keys are generated and

used by the source station and the destination station to alter frame bits, thus

avoiding disclosure to eavesdroppers.

Under shared key authentication, each wireless station is assumed to have received

a secret shared key over a secure channel that is independent from the 802.11

wireless network communications channel.

Encryption Strength

This drop-down list box will display when WEP Encryption is enabled. The key

strength is proportional to the number of binary bits comprising the key. This

means that keys with a greater number of bits have a greater degree of security and

are considerably more difficult to crack. Encryption strength can be set to either

64-bit or 128-bit. A 64-bit key is equivalent to 5 ASCII characters or 10

hexadecimal numbers. A 128-bit key contains 13 ASCII characters or 26

hexadecimal numbers. Each key contains a 24-bit header (an initiation vector)

which enables parallel decoding of multiple streams of encrypted data.

Please see 6.13 for MAC Filter, Wireless Bridge and Advanced Wireless features.

Chapter 6 Advanced Setup

You can reach this page by clicking on the following icon located at the top of the

screen.

6.1 Auto-detection setup

The auto-detection function is used for CPE to detect WAN service for either

ETHWAN or xDSL interfaces. The feature is designed for the scenario that requires

only one WAN service in different applications.

The Auto Detection page simply provides a checkbox allowing users to enable or

disable the feature. Check the checkbox to display the following configuration

options.

Enter the PPP username/password given by your service provider for PPP service

detection.

Select a LAN-as-WAN Ethernet port for auto-detect:

Select the Ethernet Port that will be used as ETH WAN during auto-detection. For

models with ETH WAN port, only ETH WAN port is available to be used as WAN port.

WAN services list for ATM mode: A maximum of 7 WAN services with

corresponding PVC are required to be configured for ADSL ATM mode. The services

will be detected in order. Users can modify the 7 pre-configured services and select

disable to ignore any of those services to meet their own requirement and also

reduce the detection cycle.

WAN services list for PTM mode: A maximum of 7 WAN services with

corresponding VLAN ID (-1 indicates no VLAN ID is required for the service) are

required to be configured for ADSL/VDSL PTM mode and ETHWAN. The services will

be detected in order. Users can modify the 7 pre-configured services and select

disable to ignore any of the services to meet their own requirements and also

reduce the detection cycle.

Click "Apply/Save" to activate the auto-detect function.

Options for each WAN service: These options are selectable for each WAN

service. Users can pre-configure both WAN services and other provided settings to

meet their deployed requirements.

Auto Detection status and Restart

The Auto-detection status is used to display the real time status of the

Auto-detection feature.

The Restart button is used to detect all the WAN services that are either detected

by the auto-detection feature or configured manually by users.

The following window will pop up upon clicking the Restart button. Click the OK

button to proceed.

Auto Detection notice

Note: The following description concerning ETHWAN is for multiple LAN port devices

only.

1) This feature will automatically detect one WAN service only. If customers require

multiple WAN services, manual configuration is required.

2) If a physical ETHWAN port is detected, the Auto Detection for ETHWAN will be

fixed on the physical ETHWAN port and cannot be configured for any LAN port;

if the physical ETHWAN port is not detected, the Auto Detection for ETHWAN will

be configured to the 4th LAN port by default and allows it to be configured for any

LAN port as well.

3) For cases in which both the DSL port and ETHWAN port are plugged in at the

same time, the DSL WAN will have priority over ETHWAN. For example, the

ETHWAN port is plugged in with a WAN service detected automatically and then

the DSL port is plugged in and linked up. The Auto Detection feature will clear

the WAN service for ETHWAN and re-detect the WAN service for DSL port.

4) If none of the pre-configured services are detected, a Bridge service will be

created.

6.2 Security

For detailed descriptions, with examples, please consult Appendix A - Firewall.

6.2.1 IP Filtering

This screen sets filter rules that limit IP traffic (Outgoing/Incoming). Multiple filter

rules can be set and each applies at least one limiting condition. For individual IP

packets to pass the filter all conditions must be fulfilled.

NOTE: This function is not available when in bridge mode. Instead, MAC Filtering

performs a similar function.

OUTGOING IP FILTER

By default, all outgoing IP traffic is allowed, but IP traffic can be blocked with filters.

To add a filter (to block some outgoing IP traffic), click the Add button.

On the following screen, enter your filter criteria and then click Apply/Save.

Consult the table below for field descriptions.

Field Description

Source IP address Enter source IP address.

Source Port (port or port:port) Enter source port number or range.

Destination IP address Enter destination IP address.

Destination Port (port or port:port)

Enter destination port number or range.

INCOMING IP FILTER

By default, all incoming IP traffic is blocked, but IP traffic can be allowed with filters.

To add a filter (to allow incoming IP traffic), click the Add button.

On the following screen, enter your filter criteria and then click Apply/Save.

Consult the table below for field descriptions.

Field Description

Filter Name The filter rule label.

IP Version Select from the drop down menu.

At the bottom of this screen, select the WAN and LAN Interfaces to which the filter

rule will apply. You may select all or just a subset. WAN interfaces in bridge mode or

without firewall enabled are not available.

Denial of Service

Denial of Services currently provides Syn-flood protection, furtive port scanner

protection and Ping of death protection. This web page allows you to

activate/de-activate them and to set the maximum average limit (packet per second)

and the maximum burst (packet amount) for each protection.

Click the Apply/Save button to save and (de)activate the protection.

6.2.2 MAC Filtering

NOTE: This option is only available in bridge mode. Other modes use IP Filtering

to perform a similar function.

Each network device has a unique 48-bit MAC address. This can be used to filter

(block or forward) packets based on the originating device. MAC filtering policy and

rules for the NexusLink 3240 can be set according to the following procedure.

The MAC Filtering Global Policy is defined as follows. FORWARDED means that all

MAC layer frames will be FORWARDED except those matching the MAC filter rules.

BLOCKED means that all MAC layer frames will be BLOCKED except those

matching the MAC filter rules. The default MAC Filtering Global policy is

FORWARDED. It can be changed by clicking the Change Policy button.

Choose Add or Remove to configure MAC filtering rules. The following screen will

appear when you click Add. Create a filter to identify the MAC layer frames by

specifying at least one condition below. If multiple conditions are specified, all of

them must be met.

Click Save/Apply to save and activate the filter rule.

Consult the table below for detailed field descriptions.

Field Description

Protocol Type PPPoE, IPv4, IPv6, AppleTalk, IPX, NetBEUI, IGMP

Destination MAC Address Defines the destination MAC address

Source MAC Address Defines the source MAC address

Frame Direction Select the incoming/outgoing packet interface

WAN Interfaces Applies the filter to the selected bridge interface

6.8 Interface Grouping

Interface Grouping supports multiple ports to PVC and bridging groups. Each group

performs as an independent network. To use this feature, you must create mapping

groups with appropriate LAN and WAN interfaces using the Add button.

The Remove button removes mapping groups, returning the ungrouped interfaces

to the Default group. Only the default group has an IP interface.

To add an Interface Group, click the Add button. The following screen will appear.

It lists the available and grouped interfaces. Follow the instructions shown

onscreen.

101

Automatically Add Clients With Following DHCP Vendor IDs:

Add support to automatically map LAN interfaces to PVC's using DHCP vendor ID

(option 60). The local DHCP server will decline and send the requests to a remote

DHCP server by mapping the appropriate LAN interface. This will be turned on when

Interface Grouping is enabled.

For example, imagine there are 4 PVCs (0/33, 0/36, 0/37, 0/38). VPI/VCI=0/33 is

for PPPoE while the other PVCs are for IP set-top box (video). The LAN interfaces are

ETH1, ETH2, ETH3, and ETH4.

The Interface Grouping configuration will be:

1. Default: ETH1, ETH2, ETH3, and ETH4.

2. Video: nas_0_36, nas_0_37, and nas_0_38. The DHCP vendor ID is "Video".

102

If the onboard DHCP server is running on "Default" and the remote DHCP server is

running on PVC 0/36 (i.e. for set-top box use only). LAN side clients can get IP

addresses from the CPE's DHCP server and access the Internet via PPPoE (0/33).

If a set-top box is connected to ETH1 and sends a DHCP request with vendor ID

"Video", the local DHCP server will forward this request to the remote DHCP server.

The Interface Grouping configuration will automatically change to the following:

1. Default: ETH2, ETH3, and ETH4

2. Video: nas_0_36, nas_0_37, nas_0_38, and ETH1.
