Parameter

Description

Enable DHCP L2 Relay

Indicates whether to enable the DHCP L2

Relay.

The DHCP relay is a process in which cross-

subnet forwarding of DHCP broadcast

packets is implemented between the DHCP

client and the DHCP server. In this manner,

the DHCP clients in different physical

subnets can obtain IP addresses which are

dynamically allocated from the same DHCP

server.

l

If

Mode

of the WAN port is

Route

, the IP

address of the ONT is obtained from

upper-layer DHCP servers in different

subnets and the user-side IP addresses are

obtained from the DHCP address pool of

the ONT.

l

If

Mode

of the WAN port is

Bridge

, the

ONT functions as a bridge. Thus, the ONT

does not have an IP address. The user-side

IP addresses are obtained from upper-

layer DHCP servers in different subnets.

Start IP Address

Indicates the start IP address in the IP address

pool on the primary DHCP server. It must be

in the same subnet as that of the IP address set

in "

LAN Host Configuration

". Otherwise,

the DHCP server fails to work normally.

End IP Address

Indicates the end IP address in the IP address

pool on the active DHCP server. It must be in

the same subnet as that of the IP address set

in "

LAN Host Configuration

". Otherwise,

the DHCP server fails to work.

Leased Time

Indicates the lease time of the IP address pool

on the active DHCP server. Options: minute,

hour, day, and week.

Enable secondary DHCP server

Indicates whether to enable the secondary

DHCP server. If the check box is selected,

you can set the secondary DHCP server.

IP Address

Indicates the IP address of the secondary

DHCP server.

Subnet Mask

Indicates the subnet mask of the secondary

DHCP server.

Start IP Address

Indicates the start IP address in the IP address

pool on the secondary DHCP server.

Parameter

Description

End IP Address

Indicates the end IP address in the IP address

pool on the secondary DHCP server.

Leased Time

Indicates the lease time of the IP address pool

on the secondary DHCP server. Options:

minute, hour, day, and week.

Option60

Indicates the option 60 field of the secondary

DHCP server. A user-side DHCP client can

obtain an IP address from the IP address pool

on the secondary DHCP server only when the

option 60 field carried by the user-side DHCP

client is the same as this setting.

5.4 WLAN

This topic describes how to perform basic and advanced configurations of the WLAN through

the Web page.

5.4.1 WLAN Configuration

1.

In the navigation tree on the left, choose

WLAN

>

WLAN Configuration

. In the pane on

the right, select the

Enable WLAN

option box. In the dialog box that is displayed, set the

basic Wi-Fi parameters, including the SSID, authentication mode, and encryption mode,

as shown in

Figure 5-16

.

describes the basic Wi-Fi parameters.

Table 5-4

Basic Wi-Fi parameters

Parameter

Description

Enable WLAN

Indicates whether to enable the wireless network. The following

parameters can be set only when the wireless network is enabled.

SSID

Indicates the name of the wireless network. It is used to

differentiate different wireless networks. It consists of a

maximum of 32 characters, without space or Tab character.A

default SSID1, named

WirelessNet

is created after the creation

of an ONT. The system can configure up to four SSIDs at a time

and cannot assign IP addresses to Wi-Fi terminals by SSID.

Parameter

Description

Associated Device

Number

Specifies the number of STAs. It ranges from 1 to 32.

Broadcast Ssid

Indicates whether to enable or hide broadcast.

l

If the option box is selected, it indicates that the SSID

broadcast function is enabled. The ONT periodically

broadcasts the SSID, that is, the name of the wireless

network. In this way, any STA can search for the wireless

network.

l

If the option box is not selected, it indicates that the SSID

broadcast function is disabled. The SSID is hidden, and the

STA cannot search for the wireless network. The SSID can

be obtained only through a request.

WMM Enable

Indicates whether to enable the QoS of the wireless network.

After the function is enabled, the video and voice QoS can be

improved.

Authentication Mode

Indicates the authentication mode for the STA to request access

to the wireless network. The mode can be Open, Shared, WPA

Pre-Shared Key, WPA2 Pre-Shared Key, WPA Enterprise,

WPA2 Enterprise, or Wi-Fi Protected Setup.

It is set to open by default, that is, the STA can access the network

without authentication.

Encryption Mode

Indicates the encryption mode for the STA to request access to

the wireless network. The encryption mode and encryption

parameters vary with the authentication mode.

l

If the authentication mode is set to

Open

, the encryption

mode can be set to

None

or

WEP

.

l

If the authentication mode is set to

Shared

, the encryption is

WEP

.

l

If the authentication mode is set to

WPA Pre-Shared Key

,

WPA2 Pre-Shared Key

,

WPA Enterprise

, or

WPA2

Enterprise

, the encryption mode can be set to

AES

,

TKIP

,

or

TKIP&AES

.

l

If the authentication mode is set to

Wi-Fi Protected Setup

,

WPS Mode

must be set to

or

Push-button

.

NOTE

l

indicates the pin-based encryption.

l

Push-button

indicates the push-button-based encryption.

When

WPS Mode

is set to

Push-button

, press the

WPS

button on

the ONT and press the WPS icon included with the STA within two

minutes, or run the WPS setup program in the STA to install the WPS

software.

NOTE

l

The security mode and encryption configured on a Wi-Fi terminal must be the same as those of an ONT. If

the TKIP&AES, or AES encryption mode is not configured on the Wi-Fi terminal, the Wi-Fi terminal may

have an old-version driver. If so, update the driver version.

l

When two SSIDs are configured, if you modify the information of an SSID, the other SSID will re-choose

a channel, causing the service to be interrupted for a few minutes.

5.5 Security

This topic describes how to configure the IP address filter, MAC address filter, DoS, and ONT

access control through the Web page.

5.5.1 IP Filter Configuration

1.

In the navigation tree on the left, choose

Security

>

IP Filter Configuration

. In the pane

on the right, enable the IP address filter function. After selecting the filter mode, click

New

. Then, in the dialog box that is displayed, configure the rule for filtering IP addresses

from the WAN interface to the LAN port, as shown in

Figure 5-17

.

Figure 5-17

IP Filter Configuration

2.

Click

Apply

to apply the configuration.

The IP address filter function is a security mechanism configured on the residential gateway. It

enables or disables all or partial ports in an Intranet IP address segment to communicate with

all or partial ports in an Extranet IP address segment. The IP address filter configuration is used

to limit communication between an Intranet device and an Extranet device.

Table 5-5

describes the parameters related to the IP address filter.
