If you make any omissions, the corresponding information will be lost.
The configuration described previously may be required if you want to host a ftp,
http, email or other server in your LAN.
Depending on the type of servers that you want to install, the parameters to
specify may differ:

5.5.5
Wireless network (depending on version)
Your Residential Gateway offered a wireless network access point service according to
the 802.11b and 802.11g standards.
Object:
This menu lets you configure all the settings of a wireless network (Wi-Fi), activate the
network and filter all the MAC addresses.
5.5.5.1
Adding a computer to the wireless network and
configuring
The default configuration of your Residential Gateway is optimised to require a minimum of
configuration operations.
However, you can customise your gateway with your own settings, using the information in
section 5.5.5.3.
1. Adding a computer
The Residential Gateway uses the MAC address (for more information, refer to section 5.5.5.2)
of the 802.11b or 802.11g wireless network component of your computer to make it appear in
the list of stations allowed to communicate over the wireless network.
The MAC address of a computer can be added to the list of MAC addresses
automatically authorised.
For this, press the
association button
(marked REG).
The Residential Gateway
switches to association mode, the WiFi/Bluetooth LED blinks.
Configure the
SSID
and the
WEP key
on this computer
and then use the computer to connect to the
Residential Gateway in WiFi mode.
The SSID and the WEP encryption key, provided by default are marked
on the casing and also on the product packaging and on your
Residential Gateway's installation CD-ROM ("
Live
b
o
x
").
The Residential Gateway allows five minutes for this configuration. During this
period, the LED continues to blink, telling you that the gateway is available to
receive settings from your computer.
If necessary, you can press the REG button again to extend the period by a further
five minutes to continue configuring.
Adding an MAC address using the association function automatically
activates protection by MAC address filtering.

2. Configuration
If the 802.11b or 802.11g wireless communication module used by your computer is a SAGEM
accessory, insert the installation CD in your drive and set up the SSID and the WEP or WPA
encryption key.
Otherwise, to configure the SSID and the WEP or WPA key on your computer, please refer to
the documentation supplied with your Wi-Fi accessory. These items can be programmed using
the application installed with your Wi-Fi accessory's drivers.
In Windows XP, configuration is possible via the properties of your wireless connection.
5.5.5.2
Some technical definitions
To use an 802.11b wireless network, you must take precautions against certain
malicious acts such as:
1)
use of the Internet connection without the knowledge of the owner of the wireless
network,
2)
snooping on data interchanged over the wireless network.
To protect yourself, the SAGEM F@st
TM
3202 offers measures to counter these malicious
acts:
¾
Against the use of the Internet connection without the knowledge of the owner of the
wireless network:
Protection by customisation of the SSID,
Protection by MAC address filtering.
¾
Against snooping on data interchanged over the wireless network:
Protection by WEP or WPA encryption.
SSID:
The SSID is the identifier of your wireless network. For your wireless network to operate, the
same SSID must be entered on your Residential Gateway and on all the computers that make
up your wireless network.
MAC address:
When filtering by MAC address is activated, the SAGEM F@st
TM
3202 allows only data from
and to predefined stations to pass.
To be known to the SAGEM F@st
TM
3202, a station must be entered, by its MAC address, in
the list of MAC filters on the Residential Gateway.
The MAC address is the identification number of the network cards.
An MAC address is an identifier which uniquely identifies an Ethernet network interface.

To obtain the MAC address of a wireless network card:
- In Windows 98: Start then Run, enter winipcfg.
- In Windows XP, 2000, Me: Start then Run, enter cmd then ipconfig /all. Confirm by
pressing Enter.
- Identify your wireless network card from the list that appears, on the "Description"
line.
- The MAC address you are looking for corresponds to the "Physical address" line. It
comprises 12 hexadecimal characters (digits from 0 to 9 or letters from A to F).
WEP:
The WEP (Wired Equivalent Privacy) key is used to encrypt the information exchanged over
your wireless network, and is shared by the sender and receiver of the message.
Like the SSID, this WEP key must be configured the same on each computer connected to your
wireless network and on your Residential Gateway.
The format of the WEP key suggested by the Residential Gateway is as defined by IEEE
802.11b.
The keys can be of different length. The longer the key, the greater the data protection. Two key
lengths are available on the Residential Gateway:
64-bit encryption key,
128-bit encryption key.
A 64-bit encryption key is made up of 5 x 2 hexadecimal encoding characters (digits
from 0 to 9 or letters from A to F).
A 128-bit encryption key comprises 13 x 2 hexadecimal-encoded characters (digits
from 0 to 9 or letters from A to F).
In the 802.11b device documentation, the 64-bit encryption key is often called a 40-bit
encryption key. In practice, it is made up of 40 bits to be configured in the Residential
Gateway and the stations, and 24 bits that are generated automatically and
transmitted in the message exchanged.
Similarly, the 128-bit encryption key is often called a 104-bit encryption key.
Note:
The selected key will be used in all cases by the Residential Gateway to encrypt
the messages to be sent. The message sent is made up of encrypted data and
the key number (key N° 1, 2, 3 or 4) used for encryption. For the station to be
able to decrypt the message received, it must therefore have the same key
configured with the same number.
