3.1.4 WLAN Clients page
OntheWLANClients pageyoucan enableaccesscontrolbasedonthe
MAC addresses of your wireless LAN clients. When access control is
enabled, only the wireless stations on the Client table are allowed
access to your wireless network. On this page, you can also activate
Wired Equivalent Privacy (WEP) and set the encryption key
parameters. Note, that unless you have encryption enabled other
WLAN clients nearby have the possibility of monitoring the traffic on
your wireless network

lower case characters only when typing the MAC address. You must
identify the wireless station by filling the Name field. Activate the
ClienttablebyselectingClienttableMACaddressfromtheAdmission
method pull-down list and clicking the Apply button. Click Remove
button if you want to remove a client from the Client table.
Encrypting wireless connection
If you want to activate WEP, you have two options:
DUsea fixed default key forall stations. Thereare four defaultkeys
available and the key is selected by clicking the corresponding
radio button. Typically, there is no need to use any other key than
number 1.
DUse a separate station-specific key. Enter this key in the Client
table Wep key field.
Before you type the encryption key, select the key length from the
pull-downlist.Availablelengthsare40bitsand128bits.Ifyouselecta
40-bit key, you must enter a key with 10 characters. If you select a
128-bit key, you must enter a key with 32 characters. The key is a
hexadecimal string, so the available characters are 0, 1, 2, 3, 4, 5, 6, 7,
8, 9, 0, a, b, c, d, e, and f.
Note
Remembertoconfigurethesamekeytoyourwirelessclient.Ifyouuse
your wireless client for web configuration, you can copythe key from
theKeyfieldandpasteittothewirelessLANclientsoftware.Thenyou
can click the Apply to activate encryption. Note, that if you enable
encryption on either client or MW1122 only, the wireless link will be
disconnected until you have enabled encryption on both devices.
There are five security modes which can be chosen from Encryption
mode pull-down list:
DNo encryption; In this mode, encryption is always disabled. If a
stationtriesshared-keyauthentication,afailedauthenticationwill
result.
DAllowed; In this mode, a station may use either open-key or
shared-key authentication. If a station uses open-key
authentication,encryption is disabled.If a stationusesshared-key
authentication, encryption is used.

DRequired; In this mode, it is mandatory to use shared-key
authentication. If open-key authentication is used, a failed
authentication will result. When a station uses shared-key
authentication,encryptionisalways used.Defaultkeysare usedif
nostation-specifickeyexists.Broadcastandmulticastdatawillbe
encrypted using the default key.
DRequired,Wifi; In this mode,a station mayuse eitheropen-key or
shared-key authentication and in both cases encryption is always
used. Default keys are used if no station-specific keys exist.
Broadcast and multicast data will be encrypted using the the
default key.
DRequired, specific keys; In this mode, a station must use
shared-key authentication and station-specific key. If the station
uses open-key authentication or station-specific key is not
available, a failed authentication will result. Successful
shared-key authentication results encryption using the
station-specific keys. Broadcast and multicast data will be
encrypted using the default key.
In most cases, it is acceptable to use default keys. Most modes also
allow concurrent use of station-specific and/or user-specific keys at
the same time. Wifi mode provides lowerauthentication support but it
supports all certified WLAN clients. Wifi mode is recommended if
other than Nokia wireless LAN cards are used.
Figures 8 and 9 show Wlan Clients page with default key and
station-specifickeys used, respectively. In Figure 8, the station“PC1”
on the Client table uses the default key 1. Additonally, the Client table
is used as a MAC address -based access control list. In Figure 9,
stations “PC1”and “PC2”use the station-specific key given in the
WEPkey field on the Clienttable.TheMACaddress-basedaccesslist
is not needed, but the default key is used to encrypt the
broadcast/multicast traffic.
Note
If you are using a station-specific key, you must also configure the
default key because it is used for broadcast.

and Routing.
Local ports
On the Local Network Local Ports sub page you can assign IP
addressestoEthernetandwirelessLANports. IfyousetPhysicalLAN
interfaces as Single subnet, you don’t have to set the IP address and
subnet mask to the WLAN port. Instead, the Ethernet IP address is
used for both LAN ports (WLAN slaved to LAN).
Note
When you click Apply, the IP addresses are changed immediately. If
the IP address of the interface you are using changes the connection
will be lost. You have to reconfigure the IP address of the accessing
host. For example, in Windows programs winipcfg.exe or
ipconfig.exe must be used first to release the old address and then to
renew to request new address.

DHCP
On the Local Network DHCP subpage you can enable/disable
Dynamic Host Control Protocol and set the Address ranges from
which the addresses are distributed to the DHCP clients on your
network. You can also set the Domain Name Server addresses here.
Start address is the first address in the address range. The Range size
defines how many addresses the range contains. Subnet mask is the
subnet mask of the addresses in the range. Primary and Secondary
DNSs set the domain name servers for the corresponding address
range. Lease time defines how often the DHCP client must renew its
lease. Domain name defines the domain name for the range.
The DHCP server can be enabled towards LAN, WLAN and
VBRIDGE (gateway interface) ports. When the DHCP server is
enabled, up to two scopes (address ranges) are automatically
generated and bound to LAN/WLAN/VBRIDGE interfaces, in this
order if the interface has an IP address. If your LAN and WLAN
interfaces have separate IP addresses you must configure two address
ranges,oneforeachinterface.InFigure13,scope(a)ishasbeenbound
to Ethernet interface and scope (b) to WLAN interface. When the
addressrangesarenotdefined,MW1122usesthedefaultvaluesforall
DHCP parameters. The default values are:
DStart address is the interface IP address
DSubnet mask 255.255.255.0
DRange size of up to 253 addresses starting from the interface IP
address.
DDNS address is the interface IP address
DLease time is 60 minutes
DDomain name is null string
If at least one address range has been defined, then IP address, DNS,
domain name and lease time, if defined, override the default values.
