Wired local network (Ethernet)
In a wired local network, PCs communicate with one another via an Ethernet cable.
When the Gigaset SE551 WLAN dsl/cable is used, it establishes the connection between
the PCs. For this it has four Ethernet LAN ports for connecting four PCs. The PCs have to
be equipped with a network socket (Ethernet). New PCs frequently already have this
socket. For older PCs you need to install an Ethernet network card. The PC and the Ethernet LAN socket on the Gigaset SE551 WLAN dsl/cable are connected using an Ethernet
cable (CAT5). There is one supplied. You can obtain additional Ethernet cables from your
retailer.
The Gigaset SE551 WLAN dsl/cable allows all PCs to access the Internet simultaneously.

Wireless local network (WLAN)
In a wireless local network (WLAN) PCs are linked without wires. For this the PCs
have to be equipped with a wireless network adapter (WLAN adapter) such as a
Gigaset PC Card 108 or a USB Adapter 108.
We generally differentiate between two types of wireless network:
u Infrastructure mode
u Ad-hoc mode
Infrastructure mode
The infrastructure mode connects wireless and wired networks with one another. In
addition to the mobile stations, the infrastructure mode needs an access point such as
the Gigaset SE551 WLAN dsl/cable. In infrastructure mode the stations in the network
always communicate via this access point. Each station that wants to be part of the wireless network must first register with the access point before it can exchange data.
The access point establishes the connection between the mobile stations of a wireless
network and a wired LAN (Ethernet) or the Internet. In this case this is described as the
device's router functionality. The router sends data packets that are not addressed to stations within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SE551 WLAN dsl/cable to connect
u wirelessly networked PCs to the Internet and
u wirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration of the Gigaset SE551 WLAN dsl/cable.
This configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network set up without an access point or router.
The mobile network components that communicate with each other directly and without wire connections form the network "ad-hoc", i.e. as and when required. All the
stations in the network have the same rights. Ad-hoc networks are used wherever
communications networks have to be set up quickly and without any existing network
infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SE551 WLAN dsl/cable has an ADSL interface that permits all stations within
its local network to access the Internet simultaneously. To be able to use this functionality you need a DSL or cable connection obtainable from an Internet provider. Find out
whether your Internet Service Provider supports parallel access by several PCs.

Assigning a Password
In the first step of the setup you can assign a Password for the user interface. When
supplied, the configuration of your Gigaset SE551 WLAN dsl/cable is not protected with
a Password. To prevent unauthorised changes to the configuration, you should set a
Password and change this Password from time to time.
ì If you have already set a Password, enter the old Password in the Current password
field.
ì Enter a new password in the New password field, and repeat it in the Confirm new
password field.
The Password can be up to 32 alphanumerical characters long. The SSID is case sensitive. Avoid proper names and all too obvious words. Mix letters and numbers
together.
Please remember:
If you ever forget your Password you will have to reset your Gigaset SE551 WLAN
dsl/cable (see page 18). Please bear in mind that this will restore all the settings to
the factory configuration. No Password will be active either.
ì To go to the next step, click on Next >.

SSID
Before the wireless network components can communicate with each other, you must
use the same SSID (Service Set Identifier).
The default SSID for the Gigaset SE551 WLAN dsl/cable is ConnectionPoint. For security
reasons you should change this SSID and deactivate SSID broadcast.
If this option is enabled, the Gigaset SE551 WLAN dsl/cable will send the SSID in all data
transmissions, and your Gigaset SE551 WLAN dsl/cable's SSID will be displayed on PCs
that have a wireless network adapter. In this case unauthorised persons could use the
SSID to gain access to your network.
ì Enter a character string of your choice in the SSID field. The SSID is case sensitive.
It can be up to 32 alphanumerical characters long.
Make a note of the SSID. You will need this to register your PC.
Please remember:
The connection to the wireless network adapters will be broken until the new SSID
has been entered in them as well.
By default SSID broadcast is inactive. For security reasons you should not change this
preconfiguration.

Setting security functions for the wireless network
In the next step you can set the encryption and authentication methods for your wireless network.
Wireless networks are even more strongly exposed to the risk of eavesdropping than
wired networks. With conventional network adapters an intruder only needs a device
with a WLAN adapter (e.g. a Notebook or a PDA (Personal Digital Assistant)) with an
appropriately configured network card in order to eavesdrop on every communication
made via a nearby wireless LAN.
The Gigaset SE551 WLAN dsl/cable makes use of effective encryption methods to prevent unauthorised eavesdropping as far as possible.
You can use the following security mechanisms:
u WPA2-PSK or WPA2-PSK / WPA-PSK (see below)
u WEP encryption (Wired Equivalent Privacy, see page 39)
We recommend using WPA2-PSK if it is supported by all components in your wireless
network.
You will find further options for setting data encryption and authentication in the
Advanced Settings menu (see page 74).

Schablone 2004_12_27
WPA2 / WPA with Pre-shared key (PSK)
WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new standard WPA2 uses AES for the encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared key, automatically changed ( "rekeying") and authenticated between the
devices after a certain period of time (Rekey Interval).
Please remember:
Every PC (network adapter) that requires access to a wireless network protected by
WPA must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's operating instructions.
ì Select the option WPA2-PSK if it is supported by all components in your wireless
network.
or
ì Select the option WPA2-PSK / WPA-PSK if some or all components in your wireless
network support WPA with the TKIP protocol.
ì Enter a key of your choice in the Pre-shared key field (min. 8 to max. 63 characters)
and confirm it by repeating the entry.
You must also set the same Pre-shared key for all wirelessly connected PCs.
ì To go to the next step, click on Next >.

WEP encryption
WEP (Wired Equivalent Privacy) is an encryption procedure for radio signals in wireless
networks and meets the standard IEEE 802.11.
If you transmit data wirelessly and not all components in your wireless network support
the higher security standard WPA (see page 38), we recommend that you activate WEPEncryption on these network components.
You can choose either the standard 64-bit key or the more robust 128-bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same
keys for encryption and decryption for the Gigaset SE551 WLAN dsl/cable and all your
wireless network adapters.
ì Select the Key length: 64 bit or 128 bit.
ì Select the Input type, i.e. whether you wish to enter the key manually or have it
generated automatically by means of a Passphrase.

– With a 128-bit encryption depth the key is exactly 26 characters long.
An example of a valid key: 234567ABC8912345DEF1234567
If you select ASCII you can use the characters 0 to 9, A to Z and a to z plus the special
characters in the ASCII character set.
– With a 64-bit encryption depth the key is exactly 5 characters long.
An example of a valid key: GIGA1
– With a 128-bit encryption depth the key is exactly 13 characters long.
An example of a valid key: GIGASET_SE551
ì Confirm the key by entering it again in the Confirm key field.
Generating the key by means of a Passphrase
ì Enter a Passphrase (up to 32 characters) and confirm it by entering it again. The key
is generated automatically.
Please remember:
u It is very important that you make a note of the key or passphrase. You will
need this information to configure the wireless network adapters properly.
u When you have concluded the Security Setup Wizard you must change the
WEP encryption on the wireless network adapters for the connected PCs in the
same way as they will not otherwise be given access to the Gigaset SE551

Attack detection
If the firewall functions of your Gigaset SE551 WLAN dsl/cable are activated, the device
monitors and limits the access of incoming traffic via the DSL connection with a function called Stateful Packet Inspection (SPI). This allows the Gigaset SE551 WLAN dsl/
cable to identify and prevent certain types of attack from the Internet, such as Denialof-Service (DoS). DoS attacks are aimed at devices and networks with Internet connections. The aim is not so much to steal data but to paralyse the computer or network to
such an extent that the network resources are no longer available. A typical hacker
attack involves making a remote computer announce that it is acting for the paralysed
device, for example, and receive the data meant for it.
You can use the Attack Detection function to change the standard firewall settings and
arrange to be notified by email about any attempted hacker attacks.
ì In the Advanced Settings – Internet – Firewall menu, select Attack Detection.
ì Select the security level for the firewall.
The default setting is Medium, which combines a high degree of security with little

Setting up the NAT function
Your Gigaset SE551 WLAN dsl/cable comes provided with the NAT (Network Address
Translation) function. With Address Mapping, several users on your local network can
access the Internet via one or more public IP addresses. In the default setting, all the
local IP address are mapped to your router's public IP address.
One feature of NAT is that data from the Internet is not allowed into your local network
unless it has been explicitly requested by one of the PCs on that network. Most Internet
applications run behind the NAT firewall without any problems. If you request Internet
pages, for example, or send and receive e-mails, the request for data from the Internet
comes from a PC on the local network and so the router allows the data through. The
router opens exactly one port for the application. A port is an internal PC address
through which the data is exchanged between a server on the Internet and a client on
a PC in the local network. Communicating via a port follows the rules of a particular protocol (TCP or UDP).
If an external application tries to send a call to a PC within the local network, the router
will block it. There is no open port via which the data could enter the local network.
Some applications, such as games on the Internet, require several links, i.e. several ports
so that the players can communicate with each other. In addition, these applications
must also be permitted to send requests from other users on the Internet to the user on
the local network. These applications cannot work if Network Address Translation (NAT)
has been activated.
Using port forwarding (the forwarding of requests to particular ports) you make the
router forward requests from the Internet for a certain service, e.g a game, to the appropriate port or ports on the PC on which the game is running.
Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this
case the Gigaset SE551 WLAN dsl/cable forwards data from the set port block to the PC
which has previously sent data to the Internet via a certain port (trigger port). This
means that approval for the data transfer is not tied to one specific PC in your network,
but only to the port numbers of the required Internet service.
Where configuration is concerned, this means:
u You have to define a so-called trigger port for the application and also the protocol
(TCP or UDP) that this port uses. Then you assign to this trigger port the public ports
that have to be opened for the application.
u The router checks all outgoing data for the port number and protocol. If it recognises
a match of port and protocol to a defined trigger port, then it will open the assigned
public ports and notes the IP address of the PC that sent the data. If data comes back
from the Internet via one of these public ports, it allows the data through and directs
it to the right PC. A trigger event always comes from a PC within the local network.
If a trigger port is addressed from outside, it is simply ignored by the router.

Schablone 2004_12_27
Please remember:
u An application that is configured for port triggering can only be run by one user in
the local network at a time.
u As long as the public ports are open, they can be used by unauthorised persons to
gain access to a PC in the local network.
When the Gigaset SE551 WLAN dsl/cable is supplied, the NAT function (Network Address
Translation) is activated, i.e. all IP addresses of PCs in the local network are converted to
the router's public IP address when accessing the Internet.
You can use the NAT settings for the Gigaset SE551 WLAN dsl/cable to

the role of the servers. It receives requests from remote users under its public IP address
and automatically redirects them to local PCs. The private IP addresses of the servers on
the local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SE551 WLAN dsl/
cable needs a mapping table of the port numbers to redirect the service requests to the
server that actually provides the service. For this, Port Forwarding has to be configured.

them forward all incoming data traffic from the Internet to this client. You can then, for
example, operate your own Web server on one of the clients in your local network and
make it accessible to Internet users.
As the exposed host your local client is directly visible to the Internet and therefore particularly exposed to risk (e.g. from hacker attacks). You should only activate this function if it is absolutely necessary (e.g. to operate a Web server) and other functions
(e.g. port forwarding) are not adequate. In this case you should take appropriate measures on the clients concerned.

Dynamic DNS
Any service you provide on the Internet can be accessed by Domain names. Your router's
Public IP address is assigned to this domain name. If your Internet Service Provider for
your local network's WAN connection assigns the IP address dynamically, the IP address
of the router can change. The assignment to the domain name will no longer be valid
and your service will no longer be available.
In this case you must ensure that the assignment of the IP address to the domain name
is regularly updated. This is handled by the dynamic DNS service (DynDNS). You can use
the DynDNS service to assign your Gigaset SE551 WLAN dsl/cable an individual static
domain name on the Internet even if it does not have a static IP address.
There are various providers on the Internet offering free DynDNS service.
The Gigaset SE551 WLAN dsl/cable uses the DynDNS service from DynDNS.org
(http://www.DynDNS.org).If you use the service of this DynDNS provider, then your
service can be reached on the Internet as a subdomain of one of the DynDNS.org
domains.

QoS (Quality of Service)
Many communication and multimedia applications require high speed and large bandwidths to transfer data between the local network and the Internet. However, for many
applications there is often only one Internet connection with limited capacity available.
QoS (Quality of Service) divides this capacity between the different applications and
provides undelayed, continuous data transfer where data packets with higher priority
are given transmission preference.
ì In the Advanced Settings – Internet menu, select the entry QoS.
ì Activate Differentiated services, i.e. the prioritisation of certain services for data
transfer between your network and the Internet.
ì In the field next to Upstream rate, enter the value for your DSL connection. The
value is determined in the contract with your Internet provider
You can determine via Priority which data packets are to be given preferential transmission. With the aid of PHB (Per Hop Behaviours) a decision is also made about whether
data packets are to be forwarded immediately before all others (EF, Expedited Forwarding), guaranteed and without data loss (AF, Assured Forwarding) or normally (BE, Best
Effort). If your application already supports QoS your application will determine the priority automatically, and this will be noted by your device for forwarding. In addition,
your device recognises certain Predefined applications and gives each data packet the
relevant priority. You can also determine which proportion of the bandwidth for your
Internet connection is to be made available for a certain class as Allocated bandwidth.
ì Select the Allocated bandwidth for the Predefined applications and for the line
(all other applications).
ì Click on OK to save and apply the changes.

Super G (108 Mbit/s)
With the aid of channel bundling, the Super G transmission mode enables wireless data
transfer up to 108 Mbps. The channel for wireless data transfer cannot be changed. You
can only use Super G if this function is supported by at least one client in your wireless
network. For the best possible data transfer rates, all clients in your LAN should support
Super G.
Please remember:
If you activate Super G as the transmission mode, but it is not supported by all components in your wireless network, then for technical reasons the transfer rate in the network may be significantly lower than the possible maximum of 108 Mbit/s.
ì Select the mode for using Super G (108 Mbit/s) for your wireless network to increase the data transmission speed. You have a choice of two modes.
– Static: Wireless transmission is at a rate of just 108 Mbps. Clients that do not
support this speed cannot connect to Access Point.
– Dynamic: If you select this transmission mode, the router accepts subscribers
that communicate at different transfer rates and adjusts to the slowest client in
the network.
ì If you do not wish to use Super G (108 Mbit/s), select Disabled in the selection
menu.

Security
On the Security screen in the Status menu you will see information about possible
security risks for your device and your network.
u System password not changed
Your device's configuration program is not effectively protected against unauthorised access as you have not changed the password since setup. The section entitled
"System Password" on page 92 describes how to avoid this security risk.
u Identification of your wireless network visible or not changed
Unauthorised users can also find your wireless network easily as you have not
changed the ID for your wireless network (SSID) since setup and have not deactivated the broadcasting of the SSID (SSID broadcast). The section entitled "Configuring wireless connections" on page 71 describes how to avoid this security risk.
u Encryption for your wireless network not activated
None of the data in your wireless network is encrypted when transmitted and can
therefore easily be intercepted. Unauthorised users can also easily access your network, your PCs and your Internet connection by this means. The section entitled
"Setting wireless security" on page 74 describes how to avoid this security risk.
u Access to your wireless network not restricted to allowed clients
Users can access your wireless network from any PC. The section entitled "Allowed

Internet. The section entitled "Setting up the NAT function" on page 61 describes
how to avoid this security risk.
u One or more of your local clients directly exposed to the Internet
One or more clients in your network are directly visible to the Internet as exposed
hosts and therefore particularly exposed to risk (e.g. from hacker attacks). You
should only activate this function if it is absolutely necessary (e.g. to operate a Web
server) and other functions (e.g. port forwarding) are not adequate. In this case you
should take appropriate measures on the clients concerned. The section entitled
"Opening the firewall for selected PCs (Exposed Host)" on page 65 describes how to
avoid this security risk.
u Remote management enabled
Any user, including unauthorised ones, who gains knowledge of the system password for your device can access your device's configuration program via the Internet. The section entitled "Setting up Remote Management" on page 93 describes
how to avoid this security risk.

Installing the printer port for network printers
Schablone 2004_12_27
Installing the printer port for network printers
Your Gigaset SE551 WLAN dsl/cable is equipped with a USB port that you can use, for
example, to connect a printer for use as the network printer.
Introduction
A network printer is a printer on which you can print your documents without it being
connected to your PC, e.g. to LPT1, the parallel interface. This has the advantage that
you only need this printer once in your network. All PCs for which it is released can
access it and work with it.
Note:
For multifunction devices (combination of printer, copier or fax) only the printer functionality is supported.
At present the printer server can only be used with selected printers that support USB
V2.0. You can obtain further information by contacting the hotline or else on the
Internet (see page 127).
In most cases a printer of this type is connected to another PC in the network. This does
indeed offer the advantage referred to above, but it has serious disadvantages:
u The printer can only be used by others if the PC to which it is connected is switched
on.
u The print job you send to the PC on which the printer depends reduces the perform-
ance (resources) of this PC.
If you use the USB port on the Gigaset SE551 WLAN dsl/cable for your printer you have
all the advantages of a network printer without the disadvantages referred to above:
u The network, and consequently also the printer, are always ready (the Gigaset SE551
WLAN dsl/cable and the printer itself must be switched on, of course).
u As it is connected to the USB printer port on your Gigaset SE551 WLAN dsl/cable it
does not detract from the performance of any other PC in the network.
To facilitate this option you must first set up a printer port on each PC wanting to use
the network printer. A printer port is an interface on the PCs which forwards the print
job to an IP address within the network.
Once you have set up this port you must install the printer driver.

Instructions for setting up a printer on the PC
Once you have installed the printer port you still cannot start printing. The printer port
is nothing more than an additional interface on your PC, comparable with the USB port.
It means that any printer you install on this port is also regarded as a local printer even
though it is located in the network and possibly remote from you.
You still need to connect and configure the printer to this port.
ì Connect the printer to the USB interface on your Gigaset SE551 WLAN dsl/cable.
The printer is installed in the same way as any other printer:
ì Go through Start – Settings – Printer and click on New Printer.
ì In the window that opens, click on Next.
ì Proceed as instructed by the printer installation wizard. Please note:
In the window in which you are prompted to specify the location of the printer you
should select Local Printer (usually the default setting).
ì Then click on Next.
ì Continue to install the printer. Select your printer and click on Next.
ì When the window appears in which you are prompted to enter the type of connection, double click on the port name Gigaset_Druckerport.
ì Then continue to install the printer and finish the installation.
Note:
The Gigaset SE551 WLAN dsl/cable's printer server does not work bidirectionally. It

Symptom
The Gigaset SE551 WLAN
dsl/cable or other PCs cannot be reached by a PC in the
connected LAN with a ping
command.
No connection to the
Gigaset SE551 WLAN dsl/
cable's configuration environment.
Possible cause and solutions
ì Make sure that TCP/IP has been installed and configured on all the PCs on the local network.
ì Check that the IP addresses have been properly
configured. In most cases you can use the
Gigaset SE551 WLAN dsl/cable's DHCP function to
assign dynamic addresses to the PCs in the LAN. In
this case, you have to configure the TCP/IP settings
of all the PCs so that they obtain the IP address
automatically.
ì
If you configure the IP addresses in the LAN
manually, remember to use the subnet mask
255.255.255.x. This means that the first three
parts of the IP address on each PC and the
Gigaset SE551 WLAN dsl/cable have to be identical.
The device also has to be configured as DNS server.
Use the ping command to check whether you can
establish a network connection to the Gigaset
SE551 WLAN dsl/cable.
ì Check the network cable between the PC you
want to use to administer the device and the
Gigaset SE551 WLAN dsl/cable.
ì If the PC you want to use is on the device's local
network, make sure that you are using the correct
IP address administration (see above).
ì If the PC you want to use is not on the router's local
network it must be authorised via Remote Management.

Access Point
An Access Point, such as the Gigaset SE551 WLAN dsl/cable, is the centre of a wireless
local network (WLAN). It handles the connection of the wireless linked network components and regulates the data traffic in the wireless network. The Access Point also serves
as an interface to other networks, e.g. an existing Ethernet LAN or via a modem to the
Internet. The operating mode of wireless networks with an Access Point is called
Infrastructure mode.
Ad-hoc mode
Ad-hoc mode describes wireless local networks (WLANs) in which the network components set up a spontaneous network without an Access Point e.g. several Notebooks in
a conference. All the network components are peers. They must have a wireless
Network adapter.
Auto Connect
Auto Connect means that applications such as Web browser, Messenger and Email
automatically open an Internet connection when they are launched. This can lead to
high charges if you are not using Flat rate. This function can be deactivated at the
Gigaset SE551 WLAN dsl/cable to save call charges.
Bridge
A bridge connects several network segments to form a joint network, e.g. to make a TCP/
IP network. The segments can have different physical characteristics, e.g. different connections such as Ethernet and wireless LANs. Linking individual segments via bridges
allows local networks of practically unlimited size.
See also: Switch, Hub, Router, Gateway
Broadcast
A broadcast is a data packet not directed to a particular recipient but to all the network
components on the network. The Gigaset SE551 WLAN dsl/cable does not pass broadcast packets on; they always remain within the local network (LAN) it administers.
BSSID
Basic Service Set ID
BSSID permits unique differentiation of one wireless network (WLAN) from another. In
Infrastructure mode the BSSID is the MAC address of the Access Point. In wireless networks in Ad-hoc mode the BSSID is the MAC address of any one of the participants.
Client
A Client is an application that requests a service from a Server. For example, an http Client on a PC in a local network requests data, i.e. Web pages from an HTTP Server on the
Internet. Frequently the network component (e.g. the PC) on which the Client application is running is also called a Client.

DHCP
Dynamic Host Configuration Protocol
DHCP handles the automatic assignment of IP addresses to network components. It was
developed because in large networks – especially the Internet – the defining of IP
addresses is very complex as participants frequently move, drop out or new ones join.
A DHCP Server automatically assigns the connected network components (DHCP Clients) Dynamic IP addresses from a defined IP pool range thus saving a great deal of configuration work. In addition, the address blocks can be used more effectively: since not
all participants are on the network at the same time, the same IP address can be
assigned to different network components in succession as and when required.
The Gigaset SE551 WLAN dsl/cable includes a DHCP server and uses it to assign automatic IP addresses to PCs in the local network. You can specify that the IP addresses for
certain PCs are never changed.
DHCP Server
See DHCP
DMZ
Demilitarised Zone
DMZ describes a part of a network that is outside the Firewall. A DMZ is set up, as it
were, between a network you want to protect (e.g. a LAN) and an insecure network
(e.g. the Internet). A DMZ is useful if you want to offer Server services on the Internet
which for security reasons are not to be run from behind the firewall or if Internet applications do not work properly behind a firewall. A DMZ permits unrestricted access from
the Internet to only one or a few network components, while the other network components remain secure behind the firewall.
DNS
Domain Name System
DNS permits the assignment of IP addresses to computers or Domain names that are
easier to remember. A DNS server must administer this information for each LAN with
an Internet connection. As soon as a page on the Internet is called up, the browser
obtains the corresponding IP address from the DNS Server so that it can establish the
connection.
On the Internet the assignment of domain names to IP addresses follows a hierarchical
system. A local PC only knows the address of the local Name Server. This in turn knows
all the addresses of the PCs in the local network and the superordinated Name Servers,
which again know addresses and the next superordinated Name Servers.
DNS server
See DNS
Domain name
The Domain name is the reference to one or more Web servers on the Internet.
The Domain name is mapped via the DNS service to the corresponding IP address.

DoS attack
Denial of Service
A DoS attack is a particular form of hacker attack directed at computers and networks
with a connection to the Internet. The aim is not so much to steal data but to paralyse
the computer or network so severely that the network resources are no longer available.
A typical hacker attack involves making a remote computer announce that it is acting for
the paralysed computer, for example, and receive the data meant for you.
DSL
Digital Subscriber Line
DSL is a data transmission technique in which a connection to the Internet can be run
at 1.5 Mbps over normal telephone lines. A DSL connection is provided by an Internet
Provider. It requires a DSL modem.
Dynamic IP address
A dynamic IP address is assigned to a network component automatically by the DHCP.
This means that the IP address of a network component can change with every login or
at certain intervals.
See also Static IP address
DynDNS
Dynamic DNS
The assignment of Domain names and IP addresses is handled by the Domain Name
Service (DNS). For Dynamic IP addresses this service is now enhanced with so-called
Dynamic DNS (DynDNS). It enables the use of a network component with a dynamic
IP address as a Server on the Internet. DynDNS ensures that a service can always be
addressed on the Internet under the same Domain name regardless of the current
IP address.
Encryption
Encryption protects confidential information against unauthorised access. With an
encryption system, data packets can be sent securely over a network. The Gigaset SE551
WLAN dsl/cable offers WEP encryption and WPA for secure data transmission over wireless networks.
Ethernet
Ethernet is a network technology for local networks (LANs) defined by the IEEE as standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100
Mbps.
Exposed Host
Exposed Host refers to a PC outside the firewall.

IGMP
Internet Group Management Protocol
IGMP is an Internet Protocol that enables an Internet computer to inform neighbouring
routers that it is a member of a multicast group. With multicasting, a computer can send
content on the Internet to several other computers that have registered an interest in
the first computer's content. Multicasting can, for example, be used for multimedia programs for media streaming to recipients that have set up multicast group membership.
Infrastructure mode
Infrastructure mode is a way of operating wireless local networks (WLANs) in which an
Access Point handles the data traffic. Network components cannot establish a direct
connection with each other as is the case in Ad-hoc mode.
Internet
The Internet is a wide-area network (WAN) linking several million users around the
world. A number of Protocols have been created for exchanging data, and these are
known collectively as TCP/IP. All participants on the Internet are identifiable by an IP
address. Servers are addressed by a Domain names (e.g. gigaset.com). Domain names
are assigned to IP addresses by the Domain Name Service (DNS).
Among the most important Internet services are:
u electronic mail (email)

IP address
The IP address is the unique network-wide address of a network component in a network based on the TCP/IP protocol (e.g. in a local network (LAN) or on the Internet). The
IP address has four parts (decimal numbers) separated by full stops (e.g. 192.168.1.1).
The IP address comprises the network number and the computer number. Depending
on the Subnet mask one, two or three parts form the network number, the remainder
forms the computer number. You can find out the IP address of your PC using the
ipconfig command.
IP addresses can be assigned manually (see Static IP address) or automatically
(see Dynamic IP address).
On the Internet Domain names are normally used instead of the IP addresses. DNS is
used to assign domain names to IP addresses.
The Gigaset SE551 WLAN dsl/cable has a Private IP address and a Public IP address.
IP pool range
The Gigaset SE551 WLAN dsl/cable's IP address pool defines a range of IP addresses that
the router's DHCP Server can use to assign Dynamic IP addresses.

LAN
Local network
A local network links network components so that they can exchange data and share
resources. The physical range is restricted to a particular area (a site). As a rule the users
and operators are identical. A local network can be connected to other local networks
or to a wide-area network (WAN) such as the Internet.
With the Gigaset SE551 WLAN dsl/cable you can set up a wired local Ethernet network
and a wireless IEEE 802.11g standard network (WLAN).
Lease time
The lease time defines the period of time for which the PCs keep the Dynamic IP address
assigned to them by the DHCP server without changing them.

NAT
Network Address Translation
NAT is a method for converting IP addresses (mostly Private IP addresses) within a network into one or several Public IP addresses on the Internet. With NAT several network
components in a LAN can share the router's public IP address to connect to the Internet.
The network components of the local network are hidden behind the router's IP address
registered on the Internet. Because of this security function NAT is frequently used as
part of the Firewall of a network. If you want to make services on a PC in the local network available on the Internet despite NAT, you can configure the Gigaset SE551 WLAN
dsl/cable as a Virtual server.
Network
A network is a group of devices connected in wired or wireless mode so that they can
share resources such as data and peripherals. A general distinction is made between
local area networks (LANs) and wide-area networks (WANs).
Network adapter
The network adapter is the hardware device that creates the connection between a network component and a local network. The connection can be wired or wireless. An Ethernet network card is an example of a wired network adapter. The Gigaset PC Card 108
and the Gigaset USB Adapter 108 are examples of wireless network adapters.
A network adapter has a unique address, the MAC address.
Port
Data is exchanged between two applications in a network across a port.The port
number addresses an application within a network component. The combination of IP
address/port number uniquely identifies the recipient or sender of a data packet within
a network. Some applications (e.g. Internet services such as HTTP or FTP) work with
fixed port numbers, others are allocated a free port number whenever they need one.

Private IP address
The private IP address (also known as the local IP address) is a network component's
address within the local area network (LAN). The network operator can assign any
address he or she wants. Devices that act as a link from a local network, such as the
Gigaset SE551 WLAN dsl/cable, have a private and a Public IP address.
Protocol
A protocol describes the agreements for communicating on a network. It contains rules
for opening, administering and closing a connection, as well as about data formats,
time frames and handling possible errors. Communications between two applications
require different protocols at various levels, e.g. the TCP/IP protocols for the Internet.
Public IP address
The public IP address (also known as the global IP address) is a network component's
address on the Internet. It is assigned by the Internet Provider. Devices that create a link
from a LAN to the Internet, such as the Gigaset SE551 WLAN dsl/cable, have a public and

network number and how many the computer number.
The subnet mask in a network administered by the Gigaset SE551 WLAN dsl/cable is
always 255.255.255.0. That means the first three parts of the IP address form the network number and the final part is used for assigning computer numbers. The first three
parts of the IP address of all network components are in this case always the same.
Super G
Super G is an extension of IEEE 802.11g. Channel bundling doubles the maximum transfer rate to 108 Mbps. Unlike other technologies (e.g. 125 Mbps technology) which work
by compressing data, here the transfer rate is actually doubled. If data is already compressed (ZIP, RAR, MP3, MPEG etc.) data compression offers no significant improvements.
Switch
A switch, like a Hub, is an element used to link different network segments or components. Unlike a Hub however, the Switch has its own intelligence that enables it to forward packets to only the subnet or network component they are meant for.

TCP
Transmission Control Protocol
The TCP Protocol is part of the TCP/IP protocol family. TCP handles data transport
between communication partners (applications). TCP is a session-based transmission
protocol, i.e. it sets up, monitors and terminates a connection for transporting data.

TCP/IP
Protocol family on which the Internet is based. IP forms the basis for every computer-tocomputer connection. TCP provides applications with a reliable transmission link in the
form of a continuous data stream. TCP/IP is the basis on which services such as WWW,
Mail and News are built. There are other protocols as well.
UDP
User Datagram Protocol
UDP is a Protocol of the TCP/IP protocol family that handles data transport between communication partners (applications). Unlike TCP, UDP is a non-session based protocol. It
does not establish a fixed connection. The data packets, so-called datagrams, are sent
as a Broadcast. The recipient is responsible for making sure the data is received. The
sender is not notified about whether it is received or not.
UPnP
Universal Plug and Play
UPnP technology is used for the spontaneous linking of home or small office networks.
Devices that support UPnP carry out their network configuration automatically once
they are connected to a network. They also provide their own services or use services of
other devices on the network automatically.
URL
Universal Resource Locator
Globally unique address of a Domain on the Internet.
Virtual server
A virtual Server provides a service on the Internet, that runs not on itself, but on another
network component. The Gigaset SE551 WLAN dsl/cable can be configured as a virtual
server. It will then direct incoming calls for a service via Port Forwarding directly to the
appropriate Port of the network component in question.
VoIP
Voice over IP
See Internet telephony
WAN
Wide Area Network
A WAN is a network that is not restricted to one particular area, such as the Internet.
A WAN is run by one or more public providers to enable private access. You access the
Internet via an Internet Provider.

WEP
Wired Equivalent Privacy
WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wireless transmissions in a WLAN against unauthorised access through Encryption of the
data transmitted.
WLAN
Wireless LAN
Wireless LANs enable network components to communicate with a network using radio
waves as the transport medium. A wireless LAN can be connected as an extension to a
wired LAN or it can form the basis for a new network.The basic element of a wireless
network is the cell. This is the area where the wireless communication takes place. A
WLAN can be operated in Ad-hoc mode or Infrastructure mode.
WLAN is currently specified in Standard IEEE 802.11. The Gigaset SE551 WLAN dsl/cable
complies with Standard 802.11g.
WPA
WPA was developed to improve the security provided by WEP. WPA uses complex procedures to generate keys, such as TKIP (Temporal Key Integrity Protocol). In addition, WPA
can use an authentication server (e.g. a RADIUS server) to increase security.
WPA-PSK
WPA Pre-shared key
Variant of WPA data encryption in which new keys are automatically generated at regular intervals by means of a keyword (Pre-shared key). The key is updated after defined
periods (Rekey Interval).
XR
eXtended Range
XR technology increases a WLAN's range and ensures better coverage of the area in the
home or office network. When activated at the Access Point, this function can considerably increase the range to the network adapters, although at the expense of the data
transfer rate.
