Introduction to Nokia MW1122
Chapter 1
Introduction to Nokia MW1122
Nokia MW1122 is an integrated ADSL (Asymmetric Digital
Subscriber Line) bridge and router which enables high-speed Internet
access for your wireless (WLAN) and Ethernet local area networks
(LAN). It multiplies the capacity of the already installed telephone
lines used traditionally for telephone and dial-up modem services.
MW1122 brings high-speed connections available for home users,
small offices and telecommuters.
Figure 1-1 Nokia MW1122
MW1122 allows you to connect your desktop and laptop PCs to
remote networks. Your PCs must be equipped with either 10Base-T
Ethernet interface or IEEE 802.1 1b standard compliant wireless LAN
card, for example Nokia C110 or Nokia C11 1 PC card. There are also

PCI cards and PC card adapters which can be used with desktop PCs. If
you want to have more than one PC connected to a Nokia MW1122
modem through the Ethernet interface, you must use a multi-port
Ethernet hub in between the PCs and Nokia MW1122 modem.
A wireless network at home or office is a powerful, easy to use network
that is similar to any other Ethernet-like local area network. The only
difference is the lack of cables needed on the traditional LAN. This
enables flexibility and mobility that has not been available before. Y ou
can use your laptop anywhere within the range of your wireless LAN
covering you home or office. Wireless LAN, defined by IEEE 802.1 1b
standard, provides a capacity of 1, 2, 5.5 and 11 Mbit/s capacity and
support for 32 concurrent wireless LAN clients and a coverage of 20 to
50 metres depending on the inner walls of your apartment, house or
office.
The ADSL high-speed Internet access may be delivered to you over
the same copper pair of wires that is used for your traditional telephony
services. As both services utilise the same pair of wires, a filter is
needed to separate them. This is called a POTS filter and it is a small
external device connected between your telephone and the telephone
wall socket.
Your Nokia MW1122 interconnects with a Digital Subscriber Line
Access Multiplexer (DSLAM) installed and maintained by your
access provider in their central office. MW1122 ADSL technology is
based on Discrete Multitone (DMT) modulation allowing a maximum
of 8 Mbit/s data transmission from the network and 800 kbit/s towards
the network. However, these figures illustrate the maximum
performance of the technology and are subjected to the physical line
conditions and the distance from you to the central office. MW1 122 is
capable of adapting to the physical line conditions and guarantees the
maximum transmission rate possible on the particular line. MW1 122
adapts its speed to the line conditions in steps of 32 kbit/s. In addition
to these physical limitations affecting your data throughput, your
Internet Service Provider (ISP) may limit your access according to
their service provisioning policy and based on your service contract.

Applications and features
Applications and features
In this chapter, we present the most common applications and features
of MW1122. The use and configuration of your Nokia MW1 122 may
be different from the configurations presented in this manual, even for
similar applications. The configurations presented in this manual
represent a typical way of using MW1122 for the corresponding
applications.
2.1 Applications
The three typical applications discussed below are the Internet access,
remote work, and office LAN interconnection.
Internet access
Your access to the Internet is provided by your Internet Service
Provider (ISP). Nokia MW1 122 connects you through your telephone
line and the ATM (Asynchronous Transfer Mode) network to the
network of your ISP, which, in turn, is connected to the Internet.
Hence, all your data goes through the ISP’s network. If you are using
only one ISP for your Internet access, your ISP may give you a limited
set of IP addresses belonging to its address space that you may utilise
in your desktop and laptop computers on your home network.
However, in many cases it is more practical to separate your own
private LAN from the ISP’s public network by using private IP
addresses. This way you are not limited to the number of public IP
addresses provided by your ISP but you can manage your own address
space independently. For this you will need to use NAPT (Network
Address Port Translation) feature available in your MW1 122 modem.

This mode of operation reduces the need to have more than one public
Internet address. Furthermore, it prevents others from seeing and
accessing your private network and therefore it acts as a simple
firewall.

Applications and features
Remote work
Another application for MW1122 is remote work. In this case the
end-to-end architecture can, for example, use PPP over Ethernet,
where a dial-up-type PPP connection is created between your home PC
and your corporate networks PPP access server based on the user name
and password you issue in your PC. The same set up could be used for
accessing the public Internet with a different user name and password.
This example naturally presumes that your ISP supports this type of
approach for providing remote work services for our company.

LAN interconnection
MW1122 can also be used for corporate branch office LAN
interconnection. Especially, when the branch office is a small and
possibly a temporary site without any existing LAN infrastructure
available, the MW1122 is highly suitable for this purpose. In such
circumstances the wireless LAN is an excellent technology to have
office coverage fast and without any additional wiring installations.
Local file and printer servers, if needed, may be connected with the
10Base-T Ethernet interface to MW1122 and all client PCs and laptops
may be using wireless LAN to access the servers, the printer, and the
corporate intranet. As a bridge, MW1122 enables all network
protocols to be used on the corporate network.

2.2.1 Interfaces
MW1122 has the following interfaces:
D Ethernet interface (LAN)
D Wireless LAN interface (WLAN)
D 8 ATM VCC interfaces
D ATM VCC management interface
D Gateway/bridge management interface. This interface is used as a
bridge host interface or gateway interface depending on the
operation mode. In this manual it is called VBRIDGE. On the
MW1122 web pages, the interface is called gateway or bridge IP
interface.
MW1122 can operate in four different main modes:
D Bridging only
D Routing/tunneling IP only
D Routing/tunneling IP, bridging all but IP
D Routing/tunneling IP and bridging all, including IP
Applications and features
The mode in which MW1122 operates depends on the configuration of
the unit’s interfaces. Table 2-1 shows the operational modes and the
corresponding interface configurations.

Table 2-1 Operational modes
LAN and WLAN interfaces
LAN and WLAN interfaces can be configured individually to bridge
and route packets. There are three different operational modes in both
LAN and WLAN interfaces:
2-6
E Copyright Nokia Networks Oy
C33902001SE_00
Applications and features
D Bridging only; only bridging is activated in the interface. In this
case the interface bridges all protocols.
D Routing only; only IP address is configured in the interface. In this
case, the interface routes IP packets.
D Bridging and routing; Bridging is activated in the interface and IP
address is configured in the interface. In this case, the interface
routes IP packets and bridges all other packets.
Slaved WLAN operation
The wireless LAN interface can be configured to operate as a slave to
the Ethernet interface. In this case, there is no need to configure the IP
address or bridging to the wireless LAN interface. The Ethernet and
the wireless LAN interface are bridged together internally and both
interfaces are treated as a single LAN interface. All LAN
configuration parameters defining bridging and IP-related parameters,
such as IP address, admin-disabled and RIP configuration address, are
used for both LAN and WLAN interfaces.
Internal host/gateway interface
There is a special host/gateway logical IP interface within MW1122
called VBRIDGE. This interface has a specific purpose in MW1122.
In applications where some A TM virtual channel connections are used
for bridging IP traffic and some other ATM virtual channel
connections are used for routing IP traffic, the VBRIDGE interface
must be used instead of LAN/WLAN IP addresses. Alternatively , this
interface is used in bridge only application when the IP address is
required for remote management purposes.
Data VCC operation
MW1122 supports the following encapsulations in each ATM data
virtual channel individually:
D RFC2684 LLC encapsulation for bridged IP (ETH-LLC)
D RFC2684 LLC encapsulation for routed IP (IP-LLC)
D RFC2364 Virtual circuit multiplexed PPP over AAL5 (PPP-VC)
D RFC2364 Virtual circuit multiplexed PPP over AAL5 used to
tunnel LAN/WLAN/VBRIDGE PPTP packets
(TUNNELED-PPP-VC)
If an IP address is given to a virtual channel interface and bridging is
enabled at that interface, then IP data at that interface is routed and all
other protocols are bridged. The only encapsulation which allows both
bridging and routing simultaneously is ETH-LLC. For example, it is
C33902001SE_00
E Copyright Nokia Networks Oy
2-7
MW1 122 Administrator Manual
possible to route ETH-LLC encapsulated packets and at the same time
bridge, for example, PPPoE packets (PPPoE packets are transported
directly over Ethernet frame, not within IP packets).
2.2.2 Routing
Routing is based on routing entries in a routing table. Static routes are
added via the management interface and dynamic routing is done using
RIP and RIPv2. Routing is done between the Ethernet 10Base-T
interface, the wireless LAN interface and the virtual channel
connection (VCC) of the A TM/ADSL interface. MW1122 supports up
to 8 simultaneous VCCs.
MW1122 supports IGMP (Internet Group Management Protocol)
proxy receive function for IP multicast applications.
2.2.3 Bridging
Bridging is supported to provide full protocol transparency. Bridging
can be used simultaneously with IP routing. MW1122 works as a
self-learning bridge supporting up to 1024 MAC addresses. Bridging
is done between the Ethernet 10Base-T interface, the wireless LAN
interface and each ATM VCC interface. Optionally, the bridging
between the VCCs can be disabled.
2.2.4 Network Address Port Translation
MW1122 supports Network Address Port Translation (NAPT) for
TCP/IP , UDP/IP and ICMP/IP protocols. When NAPT is used, a single
IP address is allocated to a VCC which leads to the public IP network.
The Ethernet subnet has private IP addressing and is not visible to the
VCC. NAPT translates the IP source address and source port number
dynamically to the VCC IP address and port number. Similarly,
packets coming from the VCC are mapped back to the original
destination addresses. NAPT allows up to hundreds of hosts to share a
single VCC IP address to the public network. The principle of Network
Address Port Translation is presented in Figure 2-4.

NAPT may restrict the operation of some IP applications. NAPT also
operates as a simple IP firewall because translation is only allowed
when the first packet is transmitted from the LAN. This means that the
NAPT table entry is created only when a packet is sent from the home
network to the Internet. With server support capability, the user can
add static entries to the NAPT table allowing the translation always in
both directions. This capability is used to add servers (HTTP, NNTP,
and FTP), which are visible to the public IP network via the VCC, on
the LAN subnet.
NAPT supports most IP-based protocols. Because NAPT operates on
the IP and transport layer , the application that includes IP address and
port within the payload will not work properly through NAPT . In many
cases, these applications can be passed through the NAPT using
Application Layer Gateway functionality (ALG). MW1 122 has ALG
for the following protocols/applications:
D ICMP
D FTP
D H.323 including NetMeeting
D CUSeeMe
D PPTP
D IRC
D IPSEC ESP tunnel mode and IKE
Note, that most IPSEC implementations will fail when passed through
NAPT. A typical reason is that the identification may fail if the
identification is based on IP address. Also, only tunnel mode without
Authentication Header (AH) works.

2.2.5 Dynamic Host Configuration Protocol
MW1122 can act as a Dynamic Host Configuration Protocol (DHCP)
server for the PCs on the end-user home network. In this mode,
MW1122 can assign up to 253+253 consecutive addresses from two
separate address ranges (that is, 253 consecutive addresses per address
range) to the PCs on the home network. Two separate address ranges
are used when LAN and WLAN are operating as separate subnets.
MW1122 can also act as a DHCP relay agent and relay the DHCP
requests to an external DHCP server.
2.2.6 ATM and ADSL
MW1122 supports up to 8 simultaneous VCCs and supports UBR
(Unspecified bit rate) traffic shaping on all VCCs. The maximum
transmit rate on each VCC is the ADSL upstream capacity. If more
than one VCC is transmitting simultaneously, the ADSL upstream
capacity is temporarily shared between these VCCs. When one VCC is
idle, the bandwidth is used by another VCC.
The ADSL transmission is based on the DMT line code. MW1122
provides a DMT line rate up to 8 Mbit/s downstream and up to 800
kbit/s upstream. The DMT transceiver is rate adaptive and capable of
providing faster rates over short distances or slower rates over long
distances. The transceiver adapts itself to the line conditions.
MW1122 supports also ADSL Lite. In the ADSL Lite mode, the
maximum line rates are 1536 kbit/s downstream and 512 kbit/s
upstream.
MW1122 supports both G.992.1 and G.992.2 ADSL
recommendations defined by ITU-T.
Rate adaptation is done in steps of 32 kbit/s. The ADSL interface of
MW1122 functions completely automatically and all configuration
related to the ADSL connection is done at the access multiplexer in the
operator’s premises. The network operator can set the data rates as a
part of the network management functionality provided by Nokia
DSLAM.
2.2.7 Point-to-Point Tunneling Protocol (PPTP)
2-10
When PPTP local tunneling is used, a local network client initialises a
PPTP-tunneled PPP connection (VPN) to Nokia MW1122. The
modem terminates the tunnel and all data from that terminated local
PPTP tunnel will be forwarded to an assigned A TM VCC by using PPP
E Copyright Nokia Networks Oy
C33902001SE_00
Applications and features
over AAL5 encapsulation. Thus, each local PPTP tunnel requires an
equivalent ATM VCC assigned to it restricting the total number of
local PPTP hosts to 8.
Local tunneling is used when there is a need to have one or more
computers connected independently to different networks. For
example, in remote work application, the rest of the family may be
using the common ISP services and one or two family members need to
gain access to their corporate networks. With local tunneling, these
remote workers may be connected to a different network than the rest
of the users.
Local tunneling is activated using the PPTP client running, for
example, in Windows The destination IP address must be MW1122
LAN/WLAN/VBRIDGE IP address depending on the configuration.
PPP packets within PPTP are mapped to the configured VCC.
MW1122 has three dif ferent ways to choose the A TM VCC that will be
used for tunneling:
D Automatic, chooses the first free VCC
D Chooses the VCC number using C:number, where number is from
1 to 8. C:number is typed after the MW1122 IP address in PC’s
PPTP client Connect To window (see Figure 2-5).
D Chooses the VCC number using N:name, where name is the
VCCx description. N:name is fed after the MW1122 IP address.

MW1 122 Administrator Manual
2.2.8 Point-to-Point Protocol over Ethernet (PPPoE)
Standard PPPoE mode is used when MW1 122 is operating as a bridge.
PPPoE protocol defines how PPP sessions are mapped into Ethernet
packets. When MW1122 operates as a bridge, this protocol is
transparent to MW1122.
2.2.9 Payload encapsulations
Both routed and bridged protocols are encapsulated in the A TM link by
using either RFC 2684 LLC/SNAP encapsulation or VC multiplexing.
MW1122 also supports PPP over AAL5 encapsulation, in which
routed protocols are first encapsulated in PPP (RFC 1661). PPP is then
encapsulated in ATM according to the IETF PPP over AAL5 using
RFC 2364 VC multiplexing or LLC/NLPID encapsulation.
2.2.10 Access list authorisation
When a wireless LAN is used, it is important to be able to control the
clients accessing to MW1122. Therefore, MAC-address-based access
control may be used. It prevents all communications to a such client
whose MAC address does not appear on the access list. When a new
client is brought to the network, its MAC address needs to be added to
the access list. This can be done manually through the local command
line interface (CLI) or with a Web browser management.
2.2.11 Wireless LAN and radio interface
MW1122 supports wireless LAN to be used as one of the interfaces.
The wireless LAN utilises Nokia C110/C111 Wireless LAN PC card
which needs to be inserted to the designated PC Card slot on the back
panel of the modem. Only Nokia C110 or C111 Wireless LAN cards
can be used. Without a wireless LAN card, MW1122 operates as a
normal ADSL terminal with one 10Base-T Ethernet interface. The
wireless LAN card can be inserted to the PC Card slot while the
modem is operating and the wireless LAN connectivity will be
achieved without restarting the modem. Only the WLAN subsytem
must be reseted through the web interface or the command line
interface.
2-12
Wireless LAN used in MW1122 is based on IEEE802.11 standard
operating at 2.4 GHz radio band. The band has been divided into
subchannels which are dependent on local regulations. Typically, in
Europe, there are 13 and, in USA, 11 channels. The transmission
E Copyright Nokia Networks Oy
C33902001SE_00
Applications and features
power is limited to 100 mW/MHz giving typical indoor coverage of 20
to 50 metres.
2.2.12 Wired Encryption Privacy (WEP)
MW1122 supports full-speed WEP encryption and both
authentication methods defined in IEEE 802.11b: Open-key and
shared-key authentication. The encryption is 40-bit RC4 WEP
encryption. Additionally, MW1122 supports 128-bit RC4 WEP
encryption.
2.2.13 Weighted Fair Queueing (Class of Service)
As a Class of Service (CoS) function, MW1122 supports Weighted
Fair Queueing (WFQ) for each ATM VCC. The CoS function ensures
that different IP traffic flows are treated fairly in the upstream (towards
the Internet) direction. This may be necessary, in some cases, because
the upstream capacity of the ADSL line is somewhat limited compared
to the Ethernet bandwidth on the office or home LAN. The WFQ CoS
function classifies IP traffic flows based on IP address, protocol and
port fields. It is capable of identifying the IP flow from all supported
payload encapsulation formats. WFQ works properly only with
IP-based protocols. If the flow is IP-based but is encrypted using IPSec
or PPP encryption, then WFQ cannot identify the flows correctly. In
this case, the default flow is used and the default flow is treated as a
single flow.
2.2.14 Management
There are three management methods in MW1122:
D Command line interface (CLI) through console serial port
D CLI via telnet
D Web browser management
The CLI allows complete configuration of the unit; the Web browser
management allows the configuration of the most frequently used
configuration parameters.
2.2.15 Dedicated management channel
The operator or the Internet Service Provider can establish a dedicated
management channel to MW1122. This channel provides access to the
C33902001SE_00
E Copyright Nokia Networks Oy
2-13
MW1 122 Administrator Manual
MW1122 management (with telnet or W eb browser) and it can be used
to upload a new software to MW1122.
The dedicated management channel is separated from the other IP
stack. It is not possible to access the other interfaces or networks
behind the data interfaces through the dedicated management channel.
Similarly , access from LAN/WLAN or data VCCs to the management
channel is blocked. The management channel supports only routing
using the following encapsulations:
D RFC2684 LLC encapsulation for bridged IP (ETH-LLC)
D RFC2684 LLC encapsulation for routed IP (IP-LLC)
D RFC2364 Virtual circuit multiplexed PPP over AAL5 (PPP-VC)
In Figure, 2-6 VCC1 is used for customers data transmission.
Administration through this channel has been disabled. The operator
or the service provider uses the management VCC for management
purposes only.

should be configured for each interface in use. The example below
shows a typical configuration in such a case.

5.1.2 Routing/tunneling IP, bridging other protocols
When the application requires routing IP packets and bridging all other
protocols, then IP address has to be configured and bridging enabled
for all relevant interfaces. The result is that IP packets will be routed
and all other packets will be bridged. In the configuration example
below , LAN and WLAN interfaces route IP traffic and bridge all other
protocols. ATM VCC1 routes IP traffic and ATM VCC2 interfaces
bridges all traffic.

5.1.3 Routing/tunneling IP , bridging all protocols including IP
When IP packets that are received from LAN/WLAN must be
routed/tunneled to some ATM VCC and bridged to some other ATM
VCC, then the VBRIDGE interface must be used as this common IP
interface for all bridged interfaces. LAN and WLAN interfaces are in
this case configures as bridge only.

5.1.5 Routing/tunneling IP only using slaved WLAN
In all of the above examples slaved WLAN interface can be used
instead of a dedicated configuration. When WLAN is slaved to LAN
interface, all traffic will be bridged between the LAN and WLAN
interfaces and treated like the traffic is received from LAN interface
only. Similarly , all traffic from ADSL/ATM channels will be directed
to the logical LAN interface where it will be internally bridged and
directed to the physical LAN and/or WLAN interface.

5.2 Typical configuration tasks
Managing MW1122
This section provides some typical configuration tasks. These
configuration examples can be done through the command line
interface.
Note
After you have made changes to the configuration, you must save the
configuration if you want it to be active also after restarting MW1 122.
5.2.1 Configuring DHCP and DNS
The DHCP server can be enabled towards LAN, WLAN, and
VBRIDGE ports. When the DHCP server is enabled, up to two address
ranges (scopes) will be automatically generated and bound to
LAN/WLAN/VBRIDGE interfaces, in this order if the interface has an
IP address. Two address ranges will be required when LAN and
WLAN interfaces separate IP addresses resulting that two different
address spaces will be used, one for each interface.
The address range defines pool of IP addresses and parameters like
default gateway, DNS addresses and domain name. The generated
default address range allows up to 253 IP addresses (C class).
Automatically generated address ranges use LAN/WLAN/VBRIDGE
IP address as gateway and DNS server addresses. If one address range
is defined, then automatic binding will be disabled. If optional address
range parameters like gateway or DNS addresses are not defined,
LAN/WLAN/VBRIDGE IP addresses are used as in automatic
binding.
C33902001SE_00
E Copyright Nokia Networks Oy
5-5
MW1 122 Administrator Manual
T ypically , when DHCP is used, the advertised DSN addresses point to
LAN/WLAN/VBRIDGE interfaces. In such cases, the DNS proxy
forwards the DNS request to statically configured DNS servers or to
DNS servers learned dynamically vie PPP/IPCP.
The following commands are used to configure DHCP and DNS
settings:
MW1122(conf-common)#dhcp?
usage: dhcp mode
dhcp address
dhcp gateway
dhcp dns
dhcp lease-time
dhcp domain-name
MW1122(conf-common)#dhcp mode server ; this enables
DHCP server
Normally, there is no need to configure the DNS addresses. If the
service provider does not support automatic DNS address allocation,
the DNS servers can be configured as shown by the following
example:
MW1122(conf-common)# dns address primary 1.2.3.4
MW1122(conf-common)# dns address secondary 1.2.3.5
MW1122(conf-common)#
5.2.2 Configuring static and dynamic routing
Routing entries in the routing table are needed in order to forward the
IP packets to the correct interface. MW1122 has both static and
dynamic routes. Static routes are configured manually and dynamic
routes are learned automatically using RIP v1 and RIP v2 protocols.
The following examples show how to configure static routes to
MW1122.
Default gateway for an interface that learns the next hop automatically:
MW1122(conf-common)# ip route 0.0.0.0 0.0.0.0 0.0.0.0
vcc1

Default gateway for an interface that requires static next hop:
MW1122(conf-common)# ip route 0.0.0.0 0.0.0.0 1.2.3.1
vcc1
E Copyright Nokia Networks Oy
C33902001SE_00
Static route for an interface that learns the next hop automatically:
MW1122(conf-common)# ip route 131.132.133.0
255.255.255.0 0.0.0.0 vcc1
Static route for an interface that requires a static next hop:
MW1122(conf-common)# ip route 131.132.133.0
255.255.255.0 1.3.5.1 vcc1
MW1122 can have only one default gateway. The interfaces that can
learn gateway/peer address dynamically can use value 0.0.0.0 instead
of the next hop address.
5.2.3 Encrypting wireless connection
The minimal WEP encryption configuration is very simple. WEP
mode has to be selected, at least one key has to be configured and the
key has to be selected. In MW1122, the possible keys are numbered
from 1 to 4. In some WLAN products the numbering may be from 0 to
3. In those cases, key 0 equals key 1 in MW1122. Four keys are
available to enable easy change of keys when the keys are changed at
different times for different clients. A simple WEP configuration is
shown in the following example:
MW1122(conf-wlan)# wep mode required
MW1122(conf-wlan)# wep key-entry 1 40-bit 0987654321
MW1122(conf-wlan)# wep default-key 1
MW1122(conf-wlan)#
Managing MW1122
If you want to use 128-bit keys, you must enter a key of 32 characters:
MW1122(conf-wlan)# wep key-entry 1 128-bit
1234567890abcdef1234567890abcdef
MW1122(conf-wlan)#
The MAC Client table and station-specific keys are configured in the
following example:
MW1122(conf-wlan)# sta pc_1 00:11:22:33:44:55
MW1122(conf-wlan)# sta pc_2 00:11:22:33:44:55 40-bit
1234567890
MW1122(conf-wlan)# sta pc_3 00:11:22:33:44:55 128-bit

5.2.4 Changing WLAN settings through the command line interface
Y our Nokia MW1122 is defined to have default settings as described in
section 4.1. Sometimes you may have to modify these settings. In this
section you can find instructions on when and how to change these
settings.
Changing WLAN network name
By default, your MW1122 has the WLAN network name MW-wxyz,
where wxyz are four last numbers of the serial number of your
MW1122. You can change this to suit your needs and make your
network uniquely identifiable. T o change the WLAN network name of
MW1122:
1. Open a telnet or CLI session to MW1122 as described earlier in
this chapter .
2. Start the configuration mode by typing
3. Go to wlan configuration level by typing wlan ENTER.
4. Give new network name by typing
new_network_name ENTER where new_network_name is your
new network name. Note, that network name is case-sensitive.
5. Remember to change the network names of your WLAN clients,
also.
configure ENTER.
network-name
Changing WLAN channel
Sometimes, if there are other wireless LAN devices or devices using
2.4 GHz frequency nearby, it may be necessary to change the WLAN
channel used by Nokia MW1122. The available channels depend on
the regulatory domain. After selecting a new channel, remember to
reset the WLAN subsystem of your Nokia MW1122 as described
below.
1. Open a telnet or CLI session to MW1122 as described earlier in
this chapter .
2. Check your current channel by typing
show wlan stat
command. The channel is shown on top of the display, on
ap-station line. The ap-station line contains the following
information: MAC address/network name/channel/region.
3. Start the configuration mode by typing configure ENTER.
4. Go to wlan configuration level by typing
wlan ENTER.
5. Set a new channel (5, for example) by typing radio-channel
europe 5 ENTER.
6. Reset wlan subsystem by going to the main mode and giving
reset wlan command.

7. Ensure that the channel has been changed by typing show wlan
stat command.
You have now changed the WLAN channel of your Nokia MW1122
and you can use the wireless LAN normally. You may need to restart
your wireless LAN clients if they do not support automatic channel
scanning. Consult the user manuals of each WLAN client for
instructions on changing their WLAN channels.
Controlling the access to your network
You can control the access to your MW1122 with an access list. By
default, this feature is off in MW1122. This means that all WLAN
clients are allowed to have access to your Nokia MW1122. Therefore it
is important that you identify your WLAN clients, add them on the
access list and activate the admission control function which prohibits
other WLAN clinets from entering your network. This is a major
security issue protecting your wireless network from outsiders. T o add
clients to the access list:
1. Consult your computer’s and WLAN clients’ manuals on how to
find out your WLAN clients’ MAC addresses. For clients running
Windows 95 and 98 operating systems, you can find out the MAC
addresses by running
winipcfg.exe and selecting WLAN card
from the menu. The MAC address is shown in the Adapter
address field.
2. Open a telnet or CLI session to MW1122 as described earlier in
this chapter .
3. Start the configuration mode by typing
configure ENTER.
4. Go to wlan configuration level by typing wlan ENTER.
5. Add an entry on the access list by giving the following command:
sta–address <entry-name> xx:xx:xx:xx:xx:xx, where
entry–name identifies the access list entry (for example, a PC host
name) and xx:xx:xx:xx:xx:xx is the MAC address of the allowed
wireless client.
6. Repeat the
sta-address command if you want to add more
clients on the access list.
7. If you want to remove WLAN clients from the access list, just type
no sta-address xx:xx:xx:xx:xx:xx, where
xx:xx:xx:xx:xx:xx is the MAC address of the wireless station you
want to remove from the list.

this chapter.Start the configuration mode by typing configure
ENTER.
2. Go to wlan configuration level by typing wlan ENTER.
3. Activate the access list by giving the admission-control
sta-address ENTER command. You can deactivate admission
control by typing no admission-control ENTER.
4. Type show on the wlan configuration level to view the activated
access list entries.
5.2.5 File system and downloading new firmware using TFTP
MW1122 has a flash file system. Some files in the file system have
special meanings. These files are:
D image.exe; primary application file.
D image.bak; secondary application file used if image.exe has been
corrupted or is missing. It is then renamed as image.exe
automatically.
D startup.cfg; primary configuration file used during startup.
D dhcp.leases; contains DHCP lease table information.
MW1122 has the following commands that can be used for file
handling:
D copy
D rename
D delete
D dir
If you use image.exe as a destination filename with the copy command
and the image.exe already exists, the existing image.exe will be
automatically renamed as image.bak. This guarantees that the
application file exists if MW1 122 loses power during SW download.

On the WLAN Clients page you can enable access control based on the
MAC addresses of the 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 in the MAC address. Y ou must
identify the wireless station by filling the Name field. Activate the
Client table by selecting Client table MAC address from the Admission
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:
D Use a fixed default key for all stations. There are four default keys
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.
D Use 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-down list. A vailable lengths are 40 bits and 128 bits. If you select a
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
Remember to configure the same key to your wireless client. If you use
your wireless client for web configuration, you can copy the key from
the Key field and paste it to the wireless LAN client software. Then you
can click the Apply to activate encryption. Note, that if you enable
encryption on either client or MW1 122 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:
D No encryption; In this mode, encryption is always disabled. If a
station tries shared-key authentication, a failed authentication will
result.
D Allowed; 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 station uses shared-key
authentication, encryption is used.
5-18
E Copyright Nokia Networks Oy
C33902001SE_00
Managing MW1122
D Required; 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, encryption is always used. Default keys are used if
no station-specific key exists. Broadcast and multicast data will be
encrypted using the default key.
D Required, Wifi; In this mode, a station may use either open-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.
D Required, 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 lower authentication support but it
supports all certified WLAN clients. Wifi mode is recommended if
other than Nokia wireless LAN cards are used.
Figures 5-5 and 5-6 show Wlan Clients page with default key and
station-specific keys used, respectively. In Figure 5-5, 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 5-6, stations “PC1” and “PC2” use the station-specific key
given in the WEP key field on the Client table. The MAC address
-based access list 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.

5.3.6 Local Network pages
The Local Network page as four sub pages: Local ports, DHCP, NAPT,
and Routing.
Local ports
On the Local Network Local Ports sub page you can assign IP
addresses to Ethernet and wireless LAN ports. If you set Physical LAN
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.

C33902001SE_00
Managing MW1122
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, one for each interface. In Figure 5-10, scope (a) has been bound
to Ethernet interface and scope (b) to WLAN interface. When the
address ranges are not defined, MW1122 uses the default values for all
DHCP parameters. The default values are:
D Start address is the interface IP address
D Subnet mask 255.255.255.0
D Range size of up to 253 addresses starting from the interface IP
address.
D DNS address is the interface IP address
D Lease time is 60 minutes
D Domain 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.

NAPT
If Network Address Port Translation (NAPT) has been activated,
servers on your local network are not visible outside your network. On
NAPT page, you can configure pinholes through which you can
provide outside access to your web server from the Internet, for
example.
In the example shown in Figure 5-11, a pinhole has been added on the
Server list. This example means that all TCP traffic coming from the
Internet through VCC1 to ports 80...89 will be mapped to the IP
address 192.168.1.15 ports 90...99 on your local network.
