6.5.4 Allowing Only Specified PCs to Be Connected to a WLAN

Function Overview

After the SSID is hidden and an optimum security mode is used, your WLAN is in a

secure state. You can prohibit certain PCs from being connected to the WLAN or allow

only specified PCs to be connected to the WLAN, thus preventing unauthorized users

from accessing the WLAN.

Through the wireless MAC filtering function of the terminal, the preceding functions can

be used after you enter the MAC addresses of the PCs to be controlled.

The wireless MAC filtering function can be implemented in the following modes:

z

Blacklist: The PCs whose MAC addresses are listed in the filtering list are prohibited

from being connected to the WLAN.

z

Whitelist: The PCs whose MAC addresses are listed in the filtering list are allowed

to be connected to the WLAN.

You can select either of the preceding modes for the wireless MAC filtering function.

The wireless MAC filtering function controls the option of allowing a PC to be connected to

the terminal through a WLAN. The MAC address filtering function described in section

6.6

"Controlling the Internet Access Rights of PCs" controls the option of allowing a PC

connected to the terminal to access the Internet.

You can set the maximum number of the devices that are allowed to be connected to a WLAN,

thus increasing the security of the

WLAN. This maximum number ranges from 1 to 32. For

example, you have only one laptop that needs to be connected to the WLAN. You can set this

maximum number to

1

. After your laptop is connected to the WLAN, other PCs cannot be

connected to the WLAN.

Configuration Example

For example, you have a desktop computer and a laptop at home. The SSID of your

WLAN is

MyNewSSID

. The desktop computer is connected to the terminal through a

accessing the WLAN, you can use the whitelist mode of the wireless MAC filtering

function. To create a whitelist and allow only your laptop to be connected to the WLAN,

do as follows:

Step 1

6.6 Controlling the Internet Access Rights of PCs

Function Overview

You can prohibit certain PCs from accessing the Internet or allow only certain PCs to

access the Internet. In addition, you can set the period during which certain computers

are not allowed to access the Internet.

Through the MAC address filtering function of the terminal, the preceding requirements

can be met after you enter the MAC addresses of the PCs to be controlled.

The MAC address filtering function can be implemented in the following modes:

z

Blacklist: The PCs whose MAC addresses are listed in the filtering list are prohibited

from accessing the Internet.

z

Whitelist: The PCs whose MAC addresses are listed in the filtering list are allowed

to access the Internet.

You can select either of the preceding modes for the MAC address filtering function.

The MAC address filtering function controls the option of allowing a PC connected to the

terminal to access the Internet. The wireless MAC filtering function controls the option of

allowing a PC to be connected to the terminal through a wireless network.

Configuration Example

For example, you have bought a PC for your child who is in a primary school. To restrict

the Internet access period of the child to from 19:00 to 20:00 in each evening and to

protect your PC from being restricted, you can use the blacklist mode of the MAC

address filtering function.

Suppose the MAC address of the PC of your child is

00:11:09:11:04:DD

.

After the function of automatically synchronizing the time of the terminal with the

network time is enabled, you need to create the following two filtering rules:

z

Rule 1: From 00:00 to 18:59 each day, prohibit the PC whose MAC address is

00:11:09:11:04:DD

from accessing the Internet. The name of this rule is

Internet

access before 19:00 in the evening

.

z

Rule 2: From 19:59 to 23:59 each day, prohibit the PC whose MAC address is

00:11:09:11:04:DD

from accessing the Internet. The name of this rule is

Internet

access after 20:00 in the evening

.

The configuration procedure is as follows:

Step 1

Log in to the Web-based configuration utility.

Step 2

In the navigation tree, choose

Advanced Setup > Security

>

Parental Control

.

Step 3

Click

Add

.

Step 4

Set the following parameters based on rule 1.

z

User Name: Internet access before 19:00 in the evening

z

Other MAC Address: 00:11:09:11:04:DD
