WEP Security Settings

To enable WEP encryption, check the “WEP” box in the “Wireless Security” screen.

Three levels of WEP encryption exists. 64-bit encryption uses a key of 10 hexadecimal digits. A

hexadecimal digit is A-F and 0-9. 128-bit encryption uses 26 digits, and 256-bit encryption uses

58 digits. A key with more digits is more secure. After selecting the key length, enter the appropriate

number of hexadecimal digits, any combination of

(0-9, A-F), for the key.

There are two “Confirmation Mode”s that are supported in WEP encryption: “Open” and “Shared”.

Using “Open” mode is recommended.

Click “Save” after completing your WEP settings.

Click on “MAC Address Filtering” under the “WIRELESS” menu on the left menu bar of the RT-

205 Web interface.

To activate MAC Address filtering, check the “Activate MAC Filtering” box.

To add the devices that will be permitted to access the RT-205:

•

Check the “Permit” box.

•

For each device to be allowed access, enter the wireless MAC address of the device (e.g.“00-

14-38-15-60-DD”) in the “ADD” field and then click the “ADD” button.

AirTies Mesh Technology

The Airties RT-205 has built-in Wireless Distribution System (WDS) Mesh Technology support.

WDSMesh Technology simplifies setup of extended or completely wireless networks. AirTies Mesh

Networks Technology that makes use of this WDS feature resolves problems such as loss of

wireless signal or limited coverage area, often encountered in multiple-story or reinforced concrete

buildings.

The Mesh Network consists of an AirTies RT-205 and one or more AirTies AP-300 Wireless Access

Point devices. The AP-300s communicate with each other via wireless Mesh protocol and act as

“repeaters”. . Signals from wireless terminals reach the closest access point automatically, and

then reach the RT-205 modem via the access points in between. In this manner, wireless coverage

area can be expanded significantly.

The following figure depicts an

AirTies Mesh Network consisting of an RT-205 and two AP-300s.

How to set up a Mesh Network with AP-300 devices and an AirTies modem supporting Mesh

Network technology is explained in detail in the AirTies AP-300 User’s Manual or on AirTies web

site http://www.airties.com

Important Guidelines for Mesh Network Setup

1. RT-205 and all repeaters should use the same wireless communication channel (for instance

channel 6).

2. On the site survey page, available repeaters’ MAC addresses can be seen.

For each repeater

select the MAC addresses of the other Repeaters that it will be directly communicating with via

Mesh.

3. The signal level should not be below “Good” (%50) in the places where repeaters are located.

4. It is recommended that all devices be assigned t the same SSID .

You will see a list of all access points detected. Choose the access point(s) you would like to

include in the Mesh network by checking the corresponding box(es).

AirTies RT-205 User Manual Rev.0.1

To complete setting up your Mesh network for each access point device you like this RT-205 to

connect to you specify this RT-205 as an access point.

The access points you have chosen must use the same wireless channel as your RT-205 modem.

To set the wireless channel of the access point device, go to “Settings” under the “Wireless” menu

of the web interface of the device.

5.

Firewall

A firewall is the primary method for keeping a computer secure from intruders. A firewall allows

or blocks traffic into and out of a private network or the user's computer.

One of the methods used by the Airties RT-102 firewall to protect your network is SPI, Stateful

Packet Inspection. SPI monitors the protocol and packet addresses being received to determine

if the information should be passed through the firewall to the connected computers. The Internet

addresses that are a source of malicious attacks are permanently blocked from accessing your

network.

You can also limit or block the Internet access of any local user by defining advanced rules.

To activate the fı'ddrewall, go to “FIREWALL” under the left menu bar of the RT-205 web interface.

Check the “Firewall is Active” box and click “Save”.

5.1

Access Control

You can allow or block a user’s access to certain Internet services by setting MAC or IP address

filters.

Go to “Access Control” under the “FIREWALL” menu in the left menu bar of the Web interface.

Check the “Activate Access Control” box.

Click “New” to define a new access restriction. This

will put you in the “IP Filters” window.

17

AirTies RT-205 User Manual Rev.0.1

Enter a name for the access rule you would like to define in the “Rule Name” field.

Access control can be defined based on local IP or MAC address (uniquely identifies the network

adapter of the device). If an access rule is defined by

MAC address, the rule defined for the device

will be valid even if the local IP address changes.

It is possible to enter the MAC or IP addresses individually or choose them from the list of client

devices in the local network.

Enter the MAC address of the device you’d like to restrict traffic from in “New MAC Address” or

IP address of the device in the “New IP Range” field. For a single IP address, enter the same value

in the two boxes that define the range. (e.g. 192.168.2.2 and 192.168.2.2). To restrict access for

all devices in an IP address range, enter the beginning and ending IP addresses (e.g. 192.168.2.2

and 192.168.2.50).

Clicking the “Add” button next to MAC Address or IP Range, will add the device to the restricted

“Clients List.

In order to remove one of the previously added clients, select it from the “Client List” and click

“Remove”.

You can select the applications you would like to restrict access to from the “Current Applications”

list. If the application you are looking for is not on the list, you can add it by clicking “New” and

entering the new application. Clicking “Add” will move the applications selected to the “Blocked

Applications” list.

Don’t forget that access to the applications in the “Blocked Applications” list

will be blocked for only those clients in the “Client List”.

To remove an application from the “Blocked Applications” list, select the application you would

like to unblock and click “Remove”.
