Nokia M11 12 is an integrated ADSL (Asymmetric Digital Subscriber
Line) bridge and router which enables high-speed Internet access for
your Ethernet local area networks (LAN). It multiplies the capacity of
the already installed telephone lines used for ISDN services. M1112
brings high-speed connections available for home users, small offices
and telecommuters.
Figure 1-1Nokia M1112
M11 12 allows you to connect your desktop and laptop PCs to remote
networks. Your PCs must be equipped with a 10Base-T Ethernet
interface. M1112 has an in-built 4-port hub, which allows easy home
network installation.
The ADSL high-speed Internet access may be delivered to you over
the same copper pair of wires that is used for your ISDN services. As

both services utilise the same pair of wires, a filter is needed to separate
them. This is called an ISDN filter and it is a small external device
connected between your telephone and the telephone wall socket.
Your Nokia M1112 interconnects with a Digital Subscriber Line
Access Multiplexer (DSLAM) installed and maintained by your
access provider in their central office. M1112 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. M1112 is
capable of adapting to the physical line conditions and guarantees the
maximum transmission rate possible on the particular line. M1112
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.

Chapter 2
Applications and features
In this chapter, we present the most common applications and features
of M1112. The use and configuration of your Nokia M1112 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 M1112 for the corresponding
applications.
Applications and features
2.1Applications
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 M1112 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 M1112 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 M1112 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.

2.2Features
M1112 can operate as a bridge and/or Internet Protocol (IP) router
between the Ethernet and the virtual channels of ADSL/ATM
interfaces supporting both dynamic and static routing.
DGateway/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
M1112 web pages, the interface is called gateway or bridge IP
interface.
M1112 can operate in four different main modes:
DBridging only
DRouting/tunneling IP only
DRouting/tunneling IP, bridging all but IP
DRouting/tunneling IP and bridging all, including IP
The mode in which M1112 operates depends on the configuration of
the unit’s interfaces. Table 2-1 shows the operational modes and the
corresponding interface configurations.

LAN interface can be configured individually to bridge and route
packets. There are three different operational modes in the LAN
interface:
DBridging only; only bridging is activated in the interface. In this
case the interface bridges all protocols.
DRouting only; only IP address is configured in the interface. In this
case, the interface routes IP packets.
DBridging 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.

C33907001SE_00
Applications and features
Internal host/gateway interface
There is a special host/gateway logical IP interface within M1112
called VBRIDGE. This interface has a specific purpose in M1112. In
applications where some ATM 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 IP address. Alternatively , this interface is
used in bridge only application when the IP address is required for
remote management purposes.
Data VCC operation
M1112 supports the following encapsulations in each ATM data
virtual channel individually:
DRFC2684 LLC encapsulation for bridged IP (ETH-LLC)
DRFC2684 LLC encapsulation for routed IP (IP-LLC)
DRFC2364 Virtual circuit multiplexed PPP over AAL5 (PPP-VC)
DRFC2364 Virtual circuit multiplexed PPP over AAL5 used to
tunnel LAN/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
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).
2.2.2Routing
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 and the virtual channel connection (VCC) of the A TM/ADSL
interface. M1112 supports up to 8 simultaneous VCCs.
M11 12 supports IGMP (Internet Group Management Protocol) proxy
receive function for IP multicast applications.
2.2.3Bridging
Bridging is supported to provide full protocol transparency. Bridging
can be used simultaneously with IP routing. M1112 works as a
C33907001SE_00
E Copyright Nokia Networks Oy
2-7
M1 1 12 Administrator Manual
self-learning bridge supporting up to 1024 MAC addresses. Bridging
is done between the Ethernet 10Base-T interface and each ATM VCC
interface. Optionally , the bridging between the VCCs can be disabled.
2.2.4Network Address Port Translation
M1112 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.

195.112.12.161
Figure 2-4Principle of Network Address Port Translation
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.
2-8
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). M1112 has ALG for
the following protocols/applications:
DICMP
DFTP
DH.323 including NetMeeting
DCUSeeMe
DPPTP
DIRC
DIPSEC 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.
2.2.5Dynamic Host Configuration Protocol
M1112 can act as a Dynamic Host Configuration Protocol (DHCP)
server for the PCs on the end-user home network. In this mode, M1 112
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 can be
used if more than 253 addresses are required on the local subnet, if two
non-contiguous ranges are needed or if an additional router with
DHCP relay is used on the local network. M1112 can also act as a
DHCP relay agent and relay the DHCP requests to an external DHCP
server.
2.2.6ATM and ADSL
M1112 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. M1112
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.
M1112 is compatible with ETSI 101 388.
C33907001SE_00
E Copyright Nokia Networks Oy
2-9
M1 1 12 Administrator Manual
Rate adaptation is done in steps of 32 kbit/s. The ADSL interface of
M1112 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.
2.2.7Point-to-Point Tunneling Protocol (PPTP)
When PPTP local tunneling is used, a local network client initialises a
PPTP-tunneled PPP connection (VPN) to Nokia M1 112. The modem
terminates the tunnel and all data from that terminated local PPTP
tunnel will be forwarded to an assigned ATM VCC by using PPP 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 M1112
LAN/VBRIDGE IP address depending on the configuration. PPP
packets within PPTP are mapped to the configured VCC. M1112 has
three different ways to choose the ATM VCC that will be used for
tunneling:
DAutomatic, chooses the first free VCC
DChooses the VCC number using C:number, where number is from
1 to 8. C:number is typed after the M11 12 IP address in PC’s PPTP
client Connect To window (see Figure 2-5).
DChooses the VCC number using N:name, where name is the
VCCx description. N:name is fed after the M1112 IP address.

2.2.8Point-to-Point Pr otocol over Ethernet (PPPoE)
Standard PPPoE mode is used when M1112 is operating as a bridge.
PPPoE protocol defines how PPP sessions are mapped into Ethernet
packets. When M1112 operates as a bridge, this protocol is transparent
to M1112.
2.2.9Payload encapsulations
Both routed and bridged protocols are encapsulated in the A TM link by
using either RFC 2684 LLC/SNAP encapsulation or VC multiplexing.
M11 12 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 W eighted Fair Queueing (Class of Service)
As a Class of Service (CoS) function, M11 12 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
C33907001SE_00
E Copyright Nokia Networks Oy
2-11
M1 1 12 Administrator Manual
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.
2.2.11 Management
There are three management methods in M1112:
DCommand line interface (CLI) through console serial port
DCLI via telnet
DWeb browser management
The CLI allows complete configuration of the unit; the Web browser
management allows the configuration of the most frequently used
configuration parameters.
2.2.12 Dedicated management channel
The operator or the Internet Service Provider can establish a dedicated
management channel to M1112. This channel provides access to the
M11 12 management (with telnet or web browser) and it can be used to
upload a new software to M1112.
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 or data VCCs to the management channel
is blocked. The management channel supports only routing using the
following encapsulations:
DRFC2684 LLC encapsulation for bridged IP (ETH-LLC)
DRFC2684 LLC encapsulation for routed IP (IP-LLC)
DRFC2364 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.

5.2Typical configuration tasks
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 M1112.
5.2.1Configuring DHCP and DNS
The DHCP server can be enabled towards LAN and VBRIDGE ports.
When the DHCP server is enabled, up to two address ranges (scopes)
will be automatically generated and bound to LAN/VBRIDGE
interfaces, in this order, if the interface has an IP address. T wo separate
address ranges can be used if more than 253 addresses are required on
the local subnet, if two non-contiguous adress ranges are needed or if
an additional router with DHCP relay is used on the local network.
5-4
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).
E Copyright Nokia Networks Oy
C33907001SE_00
Managing M1112
Automatically generated address ranges use LAN/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/VBRIDGE IP addresses are used as in automatic binding.
T ypically , when DHCP is used, the advertised DSN addresses point to
LAN/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:
M1112(conf-common)#dhcp?
usage: dhcp mode
dhcp address
dhcp gateway
dhcp dns
dhcp lease-time
dhcp domain-name
M1112(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:
M1112(conf-common)# dns address primary 1.2.3.4
M1112(conf-common)# dns address secondary 1.2.3.5
M1112(conf-common)#
5.2.2Configuring static and dynamic routing
Routing entries in the routing table are needed in order to forward the
IP packets to the correct interface. M1 112 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 M1112.
Default gateway for an interface that learns the next hop automatically:
M1112(conf-common)# ip route 0.0.0.0 0.0.0.0 0.0.0.0

Default gateway for an interface that requires static next hop:
M1112(conf-common)# ip route 0.0.0.0 0.0.0.0 1.2.3.1
vcc1
Static route for an interface that learns the next hop automatically:
M1112(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:
M1112(conf-common)# ip route 131.132.133.0
255.255.255.0 1.3.5.1 vcc1
M1112 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.
5.2.3File system and downloading new firmware using TFTP
M1112 has a flash file system. Some files in the file system have
special meanings. These files are:
Dimage.exe; primary application file.
Dimage.bak; secondary application file used if image.exe has been
corrupted or is missing. It is then renamed as image.exe
automatically.
Dstartup.cfg; primary configuration file used during startup.
Ddhcp.leases; contains DHCP lease table information.
M11 12 has the following commands that can be used for file handling:
Dcopy
Drename
Ddelete
Ddir
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 M1112 loses power during SW download.
5-6
You can update the operating software of M11 12 by downloading the
new software from a TFTP server. To download and activate new
M1112 operating software:

On the Local Network Local Ports sub page you can assign an IP
address to the Ethernet port.
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.

M1 1 12 Administrator Manual
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 SecondaryDNSs 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 and VBRIDGE
(gateway interface) ports. When the DHCP server is enabled, up to two
scopes (address ranges) are automatically generated and bound to
LAN/VBRIDGE interfaces, in this order if the interface has an IP
address. In Figure 5-6, scope (a) has been bound to Ethernet interface
and scope (b) to VBRIDGE interface. When the address ranges are not
defined, M11 12 uses the default values for all 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.

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 5-7, 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.
