14001 standards for international environmental management.

Features and applications

The router Gigaset 504 AGU's wide range of features makes it ideal for a large number
of applications.

Depending on your device, some of the features may differ from the description in this
instruction manual.

u Internet access

The router supports shared Internet access for up to 252 users via the integrated

ADSL /ADSL2+ modem. This means several users in your network can surf the Inter-

net at the same time, all using the same Internet account.

u Setting up a local area network

The router offers the following possibilities:

– Depending on the device up to four devices connected via Ethernet ports with a

transmission speed of 10 or 100 Mbps (with automatic recognition).

– Up to 252 mobile terminals connected via a radio interface with a transmission

speed of up to 54 Mbps. It complies with IEEE 802.11g standard and can work
with all products that satisfy Standard IEEE 802.11b or 802.11g.

local area network, and DNS for domain name mapping.

An introduction into the various options of establishing a local network can be found

in the appendix in section "Local area networks with Gigaset products" on page 66.

u Security functions

The router Gigaset 504 AGU offers comprehensive security features:

– Firewall protection against unauthorised access from the Internet

All PCs in the local area network use the Public IP address of the router to establish
Internet connections, making them 'invisible' to other Internet users. The router
only allows access from the Internet if it has been requested from the local area
network.

Thanks to the firewall, the router also offers comprehensive protection against
attacks from computer hackers.

5

The product series Gigaset 501/504

– Service filtering and URL blocking

The router can filter Internet access, allowing you to determine which PCs may
access which Internet services.

You can also deactivate access to certain Internet domains and sites (URL block­ing).

– Access control and encryption for the local area network

You can use various encryption methods and authentication methods (WEP, WPA/
WPA2-PSK, WPA/WPA2, MAC access control) to prevent unauthorised access to
your wireless LAN or to make data illegible to unauthorised parties. The security
settings available to you depend on the components used in your local network.

With MAC access control you can allow wireless access to selected PCs.

u Offering your own services on the Internet

– If you want to offer your own services on the Internet, you can set up the router

as a virtual server without permitting further access to the local area network.

– DMZ (Exposed Host)

This allows you to release a PC in your local area network for unlimited access
from the Internet. Note that in this case your local area network will no longer be
adequately protected against Internet attacks.

Note:

Before the PCs can communicate with the router and with each other in a local net­work, you may have to change your network settings (see page 17). Configure these
network settings on one PC first so that it can establish a connection to the router. You
can then use this PC to configure the device. To find out how to do this, refer to the
document entitled "Configuring the local area network" on the CD-ROM.

Setting up the router Gigaset 504 AGU

The router can be set up in any suitable location in the home or office. You do not need
any special wiring. However, you should comply with the following guidelines:

u Operate the router only indoors within a temperature range of 0 to +40 °C. Do not

position the router near sources of heat. Do not cover the ventilation slots. High
temperatures can damage the device.

u A mains socket for 220/230 V~ and a connection socket for the splitter or LAN must

be available in the place where you set up the router.

u Do not position the device in the immediate vicinity of stereo equipment, TV sets,

microwave ovens or the like. This may cause interference.

u Position the router so that it is as near to the centre of your wireless network as pos-

sible. The general rule is: The higher you place the antenna, the better the perform­ance. Make sure that the place where you position the router offers optimum recep­tion throughout the house, apartment or office.

Using UPnP (Universal Plug and Play)

PCs with UPnP (Universal Plug & Play) can offer their own network services and automat­ically use services offered in the network.

Note:

The operating system Windows ME, Windows XP or Windows Vista must run on the
PC. Check, if the UPnP function has been installed on the PCs operating system. Maybe
you have to install the UPnP components retroactively. Please consult the documen­tation of your operating system.

As soon as you have installed UPnP on a PC operating system and activated it on the
router, applications on this PC (e.g. Microsoft Messenger) can communicate via the
Internet without you needing to expressly authorise it. In this case, the router automat­ically implements Port forwarding, thereby facilitating communication via the Internet.

The task bar on the PC on which UPnP is installed contains an icon for the router. Click
this icon to open the user interface. On Windows XP system, this icon is also shown
under network connections.

ì In the Advanced Settings menu, select: Internet – Internet Connection.

Setting up the NAT function

The router Gigaset 504 AGU comes equipped with the NAT (Network Address Transla­tion) function. With address mapping, several users in the local network can access the
Internet via one or more public IP addresses. All the local IP addresses are assigned to
the router's public IP address by default.

One of the characteristics of NAT is that data from the Internet is not allowed into the
local network unless it has been explicitly requested by one of the PCs in the network.
Most Internet applications can run behind the NAT firewall without any problems. For
example, if you request Internet pages or send and receive e-mails, the request for data
from the Internet comes from a PC in the local network, and so the router allows the
data through. The router opens precisely one port for the application. A port in this con­text is an internal PC address, via which the data is exchanged between the Internet and
a client on a PC in the local network. Communicating via a port is subject to the rules of
a particular protocol (TCP or UDP).

If an external application tries to send a call to a PC in 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 users in the
local network. These applications cannot be run if Network Address Translation (NAT)
has been activated.

30

Configuring Advanced Settings

Using port forwarding (the forwarding of requests to particular ports) the router is
forced to send requests from the Internet for a certain service, for example a game, to
the appropriate port(s) on the PC on which the game is running.

When the router is supplied, the NAT function (Network Address Translation) is acti-
vated, i.e. all IP addresses of PCs in the local network are converted to the router's public
IP address when accessing the Internet.

31

Configuring Advanced Settings

You can use the NAT settings to configure the router to carry out the following tasks:

u Set up the router as a virtual server by configuring Port Forwarding (page 32),
u Open the firewall for a selected PC (page 34).

Note:

For the functions described below, the IP addresses of the PCs must remain
unchanged. If the IP addresses of the PCs are assigned via the DHCP server of the
router, you must select Never expires (page 38) as the setting in the Local Network
menu entry for the Lease time or assign static IP addresses for the PCs.

By default the NAT function is activated. You should only deactivate the NAT function if
you want to configure you own firewall in you local network.

ì In the Advanced Settings menu, select: Internet – Address Translation (NAT)

ì Select the required option.

Port Forwarding

If you configure Port Forwarding, the router Gigaset 504 AGU outwardly assumes the
role of the server. 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 router needs a mapping
table of the port numbers to redirect the service requests to the servers that actually
provide the service.
Port Forwarding has been configured for this purpose.

32

Configuring Advanced Settings

ì In the Advanced Settings menu, select: Internet – Address Translation (NAT) –

Port Forwarding

ì Select the required application from the Predefined Applications list.
ì Select the checkbox in the Enabled column to activate the entry.
ì Click the Add button. The data for the required service is entered on the screen.
ì Click the Delete button to delete an entry.

If the application you require is not in the list, you must manually enter the relevant data
on the screen:

ì Select the protocol for the service you are providing from the Protocol list.
ì Under Public port, enter the port number(s) of the service you are providing.

You can use

– a single port number,
– several port numbers separated by commas,
– port blocks consisting of two port numbers separated by a dash, or
– any combination of these (for example 80,90-140,180).

ì In the Local port field, enter the internal port number to which service requests are

to be forwarded.

You can only specify one port number here.

ì Enter the IP address of the PC that provides the service in the Local IP address field.

Example: The Web server has been configured to react to requests on port 8080.
However, the requests from Web sites enter the Web server via port 80 (standard
value). If you add the PC to the forwarding table and define port 80 as the public
port and port 8080 as an internal port, all requests from the Internet are diverted to
the service with the port number 80 on the Web server of the PC you have defined
with port 8080.

ì Comment: Enter a description that makes it easy to identify different entries.
ì Select the checkbox in the Enabled column to activate the entry.
ì Click the Add button to add a new entry.
ì Click the Delete button to delete an entry.
ì Click OK to apply the settings.

Configuring Advanced Settings

Opening the firewall for a selected PC (Exposed Host)

You can set up a client in your local network to be a so-called "exposed host" (DMZ). Your
device will then 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, the local client is directly visible to the Internet and therefore par­ticularly vulnerable to attacks (e.g. hacker attacks). 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 for the
clients concerned.

Note:

Only one PC per public IP address can be set up as an Exposed Host (see also Port For­warding on page 32).

ì In the Advanced Settings menu, select: Internet – Address Translation (NAT) –

Exposed Host

ì Enter the Local IP Address of the PC that is to be enabled as an Exposed Host.
ì Enter a name for the PC in the Comment field.
ì Activate Enabled by ticking the check box.
ì Click the Add button to add the entry to the list.

You can add more than one PC to the list, but you can only activate one of them.

ì Click the Delete button to delete the entry from the list.
ì Apply the settings by clicking OK.

Configuring Advanced Settings

Dynamic DNS

Any service you provide on the Internet can be accessed via a Domain name. Your
router's Public IP address is assigned to this domain name. If your Internet service pro­vider assigns the IP address for your local network's WAN connection 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 updated regularly. This task is performed by the dynamic DNS service (DynDNS). You
can use the DynDNS service to assign the router Gigaset 504 AGU an individual fixed
domain name on the Internet even if it does not have a static IP address.

Various Internet service providers offer a free DynDNS service.
If you use the service of a DynDNS provider, your service can be reached on the Internet
as a subdomain of one of the DynDNS service domains.

One possible service is DynDNS.org (http://www.DynDNS.org). If you have activated
the device's DynDNS function, it will monitor its public IP address. When this changes,
the device will open a connection to DynDNS.org and update its IP address there.

Note:
You must have an account with the service you have chosen (e.g. DynDNS.org) before
you can use the DynDNS function. Follow the instructions on the provider's Web site.
Then enter the user data when configuring the router.

ì In the Advanced Settings menu, select: Internet – Dynamic DNS

ì Activate the Dynamic DNS function.
ì Select a provider from the Service provider list.
ì Enter Domain name, User name and Password. You will have received all the nec-

essary information when you registered with your Service provider.

ì Click OK to apply the settings.

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 available with limited capacity.
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.

The QoS configuration dialogue enables you to optimise the transmission behaviour for
certain applications. For example IPTV is your favourite application and so you want to
ensure that no other application will disturb the transmission of IPTV data.

ì In the Advanced Settings menu, select: Internet – Qos.

All settings apply for the displayed connection service which you selected for processing
in the Advanced Settings – Internet screen (page 23).

ì Select the option Differentiated services, i.e. the prioritisation of certain services

for the data transfer between your network and the Internet.

For each Priority is specified which data packets are to be given priority of transfer. In
addition, PHBs (Per Hop Behaviours) are used to decide whether data packets are to be
forwarded immediately and ahead of all others (EF, Expedited Forwarding), guaranteed
and without data loss (AF, Assured Forwarding), or normally (BE, Best Effort). If your
application already supports QoS, it determines the priority automatically. Your device
recognises this when forwarding. It recognises certain Predefined applications and
assigns each packet the relevant priority. You can also define what proportion of the
bandwidth for your Internet connection is to be made available to a particular class as
Allocated bandwidth.

ì Select the Allocated bandwidth for Predefined applications.
ì Click OK to save and apply your changes.

LAN configuration

You can use the LAN configuration to define an IP address for the router Gigaset 504
AGU and configure the DHCP server.

ì In the Advanced Settings menu, select: Local Network.

Defining the private IP address for the router Gigaset 504 AGU

On this screen you can change the device's IP address. The preset IP address is

192.168.254.254. This is the Private IP address of the router. This is the address under
which the device can be reached in the local network. It can be freely assigned from the
block of available addresses. The IP address under which the router can be reached from
outside is assigned by the Internet service provider. The default Subnet mask for the
local network administered by the router is 255.255.255.0.

ì If you want to assign a different IP address to the router, enter your chosen IP address

in the boxes next to IP address.

Please make sure to note which subnet mask is set when assigning the IP address.
The preset subnet mask defines that the first three parts of the IP address must be
identical for all network components (including routers).

We recommend that you use an address from a block that is reserved for private use.
This address block is 192.168.1.1 to 192.168.255.254.

ì Adjust the Subnet mask if necessary.

The Subnet mask specifies how many address parts of the IP address must be iden-
tical for all network components (including routers).

37

Configuring Advanced Settings

Notes:

New settings can only be made after the router has been rebooted. If necessary,
reconfigure the IP address on your PC (including one that is statically assigned) so that
it matches the new configuration.

Configuring the DHCP server

The router has a DHCP server for which the factory setting is active. Consequently, the
IP addresses of the PCs are automatically assigned by the router.

Note:

u If the DHCP server for the router is activated, you can configure the network set-

ting on the PC so that the option Obtain an IP address automatically is set up.
For further information, refer to the section entitled "Configuring the local area
network" on the CD-ROM.

u If you deactivate the DHCP server, you will have to assign a static IP address for the

PCs that use the network settings.

ì To activate the DHCP server, select On.
ì If the DHCP server is active, you can define a Lease time. The least time indicates

how long the client may use the allocated IP configuration.

Note:

If you select Never expires, the IP addresses are never changed. Activate this
option if you want to make NAT or firewall settings using the IP addresses of the
PCs; otherwise you have to assign static IP addresses to these PCs.

ì Define the range of IP addresses the router should use to automatically assign IP

addresses to the PCs. Define the First issued IP address and the Last issued IP
address.

ì You can define the name of a domain (Windows workgroup) in the Domain name

field.

ì Apply the settings by clicking OK.

Assigning static IP addresses to individual PCs

Even if you have activated the DHCP server, you can still assign a static IP address to indi­vidual PCs (e.g. when setting up these PCs for NAT functions).

ì Enter the MAC address of the PC to which you want to assign a static IP address.
ì Enter the IP address you wish to assign to the PC.

Configuring wireless connections

The WLAN function of your router Gigaset 504 AGU is deactivated on delivery. You can
activate it on this page.

If you have implemented wireless PC communication via the router, you should improve
the security settings of your wireless network via the Advanced Settings – Wireless

Network menu. You can carry out the following functions:

Wireless Network Activate the wireless module of the router and specify basic

settings for your wireless network, for example SSID,
Transmiss ion mode or Sending power.

Encryption Set up Encryption for wireless transmissions (page 41).

Allowed Clients Restrict access to the LAN of the router (page 45).

WDS Setting Activate the repeater function (Wireless Distribution

System, WDS) and define repeaters to increase the range of
your WLAN (see page 46).

ì In the Advanced Settings menu, select: Wireless Network.

ì Select On for the Wireless Network.

Devices can only log in wirelessly if the WLAN module of the router is activated.

You can now make the settings for the wireless network.

Channel

All clients in the network use the set radio channel for wireless data transfer. You can
choose between various channels, depending on your current location.

ì Select Automatic so that the best channel for transmitting the data is used automat-

ically.

39

Configuring Advanced Settings

SSID

For the wireless network components to be able to communicate with one another, you
must use the same SSID (Service Set Identifier).

The default SSID for the router is AIShamil. For security reasons you should change this
SSID.

ì Enter a character string of your choice. The SSID is case-sensitive. It can contain up

to 32 characters. Use a combination of letters, digits and special characters.

Note:

The connection to the wireless network adapters will be interrupted until you have
entered the new SSID in them as well.

SSID broadcast

If this option is enabled, the router will send the SSID in all data transfers and the SSID
of the router will be displayed on PCs that have a wireless network adapter. In this case,
hackers could use the SSID to detect your network.

If SSID broadcast is deactivated, the SSID of the router will not be displayed. This
increases protection against unauthorised access to your wireless network. Make a note
of the SSID. You will need it to log on to the PC.

ì Select Off to deactivate SSID broadcast.

To protect your wireless network, you should also enable encryption of data transmis­sions (page 41).

Tra nsmission m ode

The IEEE 802.11g standard permits data transfer up to 54 Mbit/s, and the IEEE 802.11b
standard up to 11 Mbit/s. Choose IEEE 802.11g only to ensure the best possible data
transfer rates in your network. To operate clients with older wireless network adapters
in your network, select IEEE 802.11b/g (mixed).

ì Select the required transmission mode for your wireless network.

Sending power

ì Select the required sending power for your device.

It is recommended that you select a sending power with a range to suit the spatial
environment of your local network. A much greater range makes it easier to eaves­drop on your wireless data transfer.

ì Click OK to apply the settings.

Configuring Advanced Settings

Setting encryption

If you are sending data over radio channels, we recommend that you activate encryp­tion (WEP or WPA) on the components in the wireless network. WPA offers greater secu­rity than WEP. You should therefore select WPA encryption if it is supported by all com­ponents in your wireless network.

WPA-PSK is a more efficient method for protecting wireless networks. Dynamic keys,

based on TKIP (Temporal Key Integration Protocol) offer increased security. The new
WPA2-PSK standard is based on AES.

ì In the Advanced Settings menu select: Wireless Network – Encryption

The following security mechanisms are currently available:

u WPA2-PSK and WPA2-PSK/WPA-PSK (page 41)
u WEP encryption (Wired Equivalent Privacy, page 42)

Note:

If you want to use the repeater function of your router (page 46) you can only use WEP
encryption.

WPA2-PSK and WPA-PSK/WPA2-PSK

WPA with pre-shared key (WPA-PSK)

WPA-PSK is a special WPA mode for private users and users in small companies without

their own authentication server. After a certain period of time (Rekey interval), encryp­tion keys are automatically generated with the pre-shared key, automatically changed
("rekeying") and authenticated between the devices.

The standard of encryption available to you depends on the components in the wireless
network. Every PC (network adapter) that requires access to a WPA-protected wireless
network must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's user guide. If all components support WPA2, select

WPA2-PSK. If you are using network adapters that only support WPA, select WPA-PSK/

and will receive an appropriate error message.

If you have inadvertently denied all PCs access to the router, you have two options:

u You can completely reset the router (page 10).

u You can connect a PC to the router using one of the LAN connections. As MAC

access control only affects PCs that are connected wirelessly, you can use this PC
to change the configuration.

Repeater function (WDS)

WDS (Wireless Distribution System) allows you to extend the range of your wireless net­work using a repeater. A repeater located at the outer range of a wireless network
ensures that data is forwarded between WLAN clients in this wireless network and cli­ents within its own wireless range. Repeaters and access points thereby form a common
wireless network within which all clients can be moved about freely. Clients automati­cally set up a connection to the next access point / repeater (roaming). For security pur­poses you must determine which access points / repeaters are to form a common wire­less network.

If you want to use a repeater in your wireless network you must activate the Wireless
Distribution System (WDS) function.

Note:

WDS can only be used with WEP encryption or without encryption. If you use WPA-PSK
encryption (default) you have to change the encryption of your wireless network. For
information refer to the section "Setting encryption" on page 41.

ì In the In the Advanced Settings menu select: Wireless Network – WDS Setting
ì To activate WDS select the On option next to Wireless distribution system.

The environment is scanned for wireless networks in rage. If the search has been com­pleted successfully the networks are displayed.

All repeaters/access points in range are displayed with the following information:

– SSID
– Mac address

– Channel

The Signal strength of the connection to the repeater, if one exists, is shown as a per­centage. You can use this data to determine the best possible location for your repeater.

You can register a maximum of three repeaters to extend your WLAN.

You can enter additional repeaters manually.

ì Click the Add button to register a repeater in your wireless network.
ì Click the Delete button to remove a repeater from your wireless network.

ì Check whether the mains adapter is connected to

the router and a power outlet.

ì Check whether the power outlet and the mains

adapter are working properly. If the mains adapter
is not working properly, contact our customer serv­ice unit (see Quick Start Guide).

ì If your router has an On button: Check whether the

device is plugged in.

ì Wait until the integrated DSL modem has com-

pleted its synchronisation. This procedure can take
up to 10 minutes.

ì The LED will also flash (at regular intervals) if no

DSL cable is attached.

ì Check the DSL cable. Check that the DSL cable is

properly connected to the DSL port and the splitter.

62

Symptom Possible cause and solutions

The LAN LED on a con-
nected device does not light
up.

No LAN connection

ì Make sure the connected device is turned on.
ì Check whether the Ethernet cable is plugged in.
ì Check that you are using the right cable type

(CAT5) and that the cable is not too long (<100m).

ì Check that the network card on the connected

device and the cables are not defective. If neces­sary, replace a defective network card or cable.

ì Use the Windows device manager (My Computer –

Properties) to check whether the network card is

functioning. If you see a red cross or a question
mark, the driver may not have been installed or
there is a resource conflict. Follow the Windows
instructions to remedy the problem.

You cannot connect to the
Internet.

ì Check whether the Connect manually option is

activated. If it is, connections cannot be opened
automatically.

ì Select Connect on demand or Always on. If you

are on a time-based tariff, this option can result in
high connection charges (see page 26).

ì The connection may have been terminated manu-

ally with the Connect on demand option selected.

– Restore the connection again manually using the

Connect button.

Or

– Restart the router.
In both cases, the Connect on demand setting will

be active again.

ì Check whether the data entered for your Internet

connection matches what your Internet service
provider has specified.

Appendix

Symptom Possible cause and solutions

You cannot open a connec­tion to the router from a
wireless device.

u Either encryption has been activated on the router

but not on the wireless network adapter, or an
incorrect key is in use.

ì Activate the required encryption on the network

adapter with the correct key.

If you do not know the key, repeat key entry
(page 41) via a PC connected via cable to the router
and enter the new key on the network adapter.

Alternatively, you can reset the router (page 10)
and then reconfigure encryption.

Warning: Please bear in mind that this will reset
the entire configuration to the factory settings.

u MAC access control is activated, but the PC is not

included in the MAC address list.

ì Enter the PC in the MAC address list.

The router or other PCs can­not be reached by a PC in the
connected LAN using a
ping command.

You cannot open a connec­tion to the configuration
environment of the router.

ì Make sure that TCP/IP has been installed and con-

figured on all the PCs in the local network.

ì Check that the IP addresses have been correctly

configured. In most cases you can use the DHCP
function of the router 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.

If you configure IP addresses in the LAN manually,
remember to use the same subnet mask for all PCs
in the LAN. This means that the masked part of the
IP address on each PC and on the router has to be
identical.

ì Use the ping command to check whether you can

establish a network connection to the router.

ì Check the network cable between the PC you want

to use to administer the device and the router.

ì If the PC you want to use for administering the

device is in the router's local network, make sure
that you are using the correct IP address range
(see above).

ì If the PC you want to use for administering the

device is not in the router's local area network, this
PC must be authorised for remote management.

Appendix

Wired local area network (Ethernet)

In a wired local area network, PCs communicate with one another via an Ethernet cable.
When the router Gigaset 504 AGU is used, it establishes the connection between the
PCs. For this the 504 series has four Ethernet LAN ports for connecting four PCs. The 501
series has one Ethernet LAN port. The PCs have to be equipped with a network port (Eth­ernet).

New PCs frequently already have this port. For older PCs you need to install an Ethernet
network card.

The PC and the Ethernet LAN port on the router are connected using an Ethernet cable
(CAT5). One Ethernet cable is supplied. Additional ones can be obtained from your
retailer.

The router Gigaset 504 AGU allows all PCs to access the Internet simultaneously.

Appendix

Wireless local area network (WLAN)

In a wireless local area network (WLAN), PCs are linked without wires or cables. The PCs
have to be equipped with a wireless local area network adapter (WLAN adapter), for
example with a Gigaset USB Adapter 54.

There are two types of wireless network:

u Infrastructure mode
u Ad-hoc mode

Infrastructure mode

Infrastructure mode connects wireless and wired networks with one another. In addi­tion to the mobile stations, infrastructure mode needs an access point such as the router
Gigaset 504 AGU. In infrastructure mode, the stations in the network always communi­cate via this access point. The access point sets up the wireless network on a permanent
basis. 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 router Gigaset 504 AGU to connect

u wirelessly networked PCs to the Internet and
u wirelessly networked PCs to an Ethernet network.

Infrastructure mode is the default configuration for the Gigaset 504 AGU.

Ad-hoc mode

An ad-hoc network is a wireless network that has been configured without an access
point or a router. The mobile network components that communicate with each other
dire ctly and w irelessly form the network on an "ad-hoc" bas is, 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 there is no existing net­work infrastructure, and where the participants are on the move.

Appendix

Linking wireless networks with the Internet

The router Gigaset 504 AGU has an ADSL interface that permits all stations within its

Glossary

Glossary

Access point

An access point, such as the router Gigaset 504 AGU, 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, for example 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 compo-
nents set up a spontaneous network without an Access point, for example several Note­books in a conference. All the network components are peers. They must have a wire­less Network adapter.

ADSL /ADSL2+

Asymmetric Digital Subscriber Line (ADSL) and ADSL 2+ are special types of DSL data
transfer technology.

AES

Advanced Encryption Standard

AES is an encryption system, which was published as a standard in October 2000 by the
National Institute of Standards and Technology (NIST). It is used for WPA encryption. A
distinction is made between the three AES variants AES-128, AES-192 and AES-256 on
the basis of the key length.

Auto connect

Auto connect means that applications such as Web browser, Messenger and E-mail
automatically open an Internet connection when they are launched. This can lead to
high charges if you are not using Flat rate. To avoid this, you can select the manual con­nect option on the router Gigaset 504 AGU.

Bridge

A bridge connects several network segments to form a joint network, for example to
make a TCP/IP network. The segments can have different physical characteristics, for
example different cabling as with Ethernet and wireless LANs. Linking individual seg-
ments 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 in the network. The router Gigaset 504 AGU does not pass on broadcast
packets; they always remain within the local network (LAN) it administers.

76

Glossary

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 net-

works 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 applica-

tion 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 of the complexity involved in defining IP addresses in large networks
– especially the Internet – as participants frequently move, drop out or new ones join.
A DHCP server automatically assigns the connected network components (DHCP Cli-

ents) Dynamic IP addresses from a defined IP pool range thus saving a great deal of con-

figuration 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 router Gigaset 504 AGU 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 a non-secure network
(e.g. the Internet). A DMZ is useful if you want to offer Server services on the Internet
that are not to be run from behind the firewall for security reasons 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.

77

Glossary

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 superordinate name servers,
which again know addresses or the next superordinate 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
th e co mpu ter or n etwork so s everel y th at the network resources are no longer available.
A typical hacker attack involves making a remote c ompute r an nou nce tha t it is a cting for
the paralysed computer, for example, and receive the data intended for you.

DSL

Digital Subscriber Line

DSL is a data transfer technique in which a connection to the Internet can be run at high
speed over normal telephone lines. A DSL connection is provided by an Internet service

provider. It requires a DSL modem.

Dynamic IP address

A dynamic IP address is assigned to a network component automatically by 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

78

Glossary

DynDNS

Dynamic DNS

The assignment of Domain names and IP addresses is handled by the Domain Name
Service (DNS). This service is now enhanced with so-called Dynamic DNS (DynDNS) for

Dynamic IP addresses. This 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 router Gigaset
504 AGU offers WEP encryption and WPA for secure data transfer over wireless net­works.

Ethernet

Ethernet is a network technology for local networks (LANs) defined by the IEEE as stand-
ard IEEE 802.3. Ethernet uses a base-band cable with a transfer rate of 10 or 100 Mbps
or 1 Gbps.

File Server

See Server

Firewall

Firewalls are used by network operators as protection against unauthorised external
access. This involves a whole bundle of hardware and software actions and technologies
that monitor and control the data flow between the private network to be protected and
an unprotected network such as the Internet.

IEEE 802.11

IEEE 802.11 is a standard for wireless LANs operating in the 2.4 GHz or 5 GHz band. In

so-called Infrastructure mode, terminals can be connected to a base station (Access

point) or they can connect with each other spontaneously (Ad-hoc mode).

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.

Glossary

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 protocol stack. All participants on the Internet can be iden­tified by an IP address. Servers are addressed by Domain names (e.g. gigaset.com).
Domain names are assigned to IP addresses by the Domain Name Service (DNS).

These are some of the main Internet services:

u Electronic mail (e-mail)
u The World Wide Web (WWW)
u File transfer (FTP)
u Discussion forums (Usenet / Newsgroups)

Internet service provider

An Internet service provider offers access to the Internet for a fee.

Internet telephony

Transmission of voice via the Internet (Voice over IP).

IP

Internet protocol

The IP Protocol is one of the TCP/IP protocols. It is responsible for addressing parties in a
network using IP addresses and routes data from the sender to the recipient. It decides
the paths along which the data packets travel from the sender to the recipient in a com­plex network (routing).

IP address

The IP address is the unique network-wide address of a network component in a net­work based on the TCP/IP protocols (e.g. in a local area network (LAN) or on the Inter-

net). The IP address has four parts (each with up to three-position digit sequences) sep-

arated 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 form 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. The DNS
is used to assign domain names to IP addresses.

The router Gigaset 504 AGU has a Private IP address and a Public IP address.

NAT

Network Address Translation

NAT is a method for converting IP addresses (Private IP addresses) within a network into
one or several Public IP addresses on the Internet. With NAT, several network compo-
nents 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 router Gigaset 504 AGU 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 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 54
and the Gigaset USB Adapter 54 are examples of wireless network adapters.

A network adapter has a unique address, the MAC address.

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 service provider. Devices that cre-
ate a link from a LAN to the Internet, such as the router Gigaset 504 AGU, have a public
and a Private IP 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.

Port forwarding

In port forwarding, the router Gigaset 504 AGU directs data packets from the Internet
that are addressed to a particular Port to the corresponding port of the appropriate net­work component. This enables servers within the local network to offer services on the
Internet without them needing a Public IP address.

Private IP address

The private IP address (also known as the local IP address) is a network component's
address within the local 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 router
Gigaset 504 AGU, have a private and a Public IP address.

Protocol

A protocol describes the agreements for communicating in a network. It contains rules
for opening, administering and closing a connection, as well as in relation to data for­mats, time frames and possibly troubleshooting. Communication between two applica­tions requires different protocols at various levels, for example the TCP/IP protocols for
the Internet.

PVC

Permanent Virtual Circuit

A permanent virtual circuit is a logical connection in an ATM network.

Glossary

Repeater

A repeater extends the range of a wireless local network by relaying data from the

Access point to additional PCs or Network adapters.

Roaming

Roaming extends the range of a wireless LAN by using several Access points that use the
same SSID and the same radio channel and are linked via Ethernet. The PCs in the net­work can switch dynamically between several access points without losing the existing
network connection.

Router

A router directs data packets from one local network (LAN) to another via the fastest
route. A router makes it possible to connect networks that have different network tech­nologies. For example, it can link a local network with Ethernet or WLAN technology to
the Internet.

See also: Bridge, Switch, Hub, Gateway

Server

SNMP

Simple Network Management Protocol

The SNMP Protocol is part of the TCP/IP protocol family. It provides a simple procedure
for administering the network based on a system of shared information for manage­ment data and network management messages (known as traps) and reports the occur­rence of events within the monitored network (e.g. an alarm message or notification of
configuration changes).

SPI

Stateful Packet Inspection

Your device uses SPI to monitor and limit access by traffic incoming from the Internet.
This allows it to identify and block certain types of attack such as Denial of Service (DoS).
A typical DoS attack may involve a remote computer paralysing a system and then
claiming to be the paralysed device in order to receive data intended for it.

85

Glossary

SSID

Service Set Identifier

The SSID is used to identify the stations in a wireless network (WLAN). All wireless net­work components with the same SSID form a common network. The SSID can be
assigned by the network operator.

Static IP address

A static IP address is assigned to a network component manually during network con­figuration. Unlike the Dynamic IP address, a static (fixed) IP address never changes.

Subnet

A subnet divides a network into smaller units.

Subnet mask

The subnet mask determines how parts of IP addresses of a network represent the net-
work number and how many the computer number.

If the subnet mask is in a network that is administered by the router Gigaset 504 AGU,
for example 255.255.255.0, that means the first three parts of the IP address form the
network number and only the final part can be used for assigning host numbers. The
first three parts of the IP address of all network components are therefore always the
same in this case.

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.

It will then direct incoming calls for a service via Port forwarding directly to the appro­priate Port of the network component in question.

VLAN
Virtual Local Area Network

A VLAN is a virtual local network within a physical network. A widely disseminated tech­nical implementation of VLANs is defined partially in the Standard IEEE 802.1Q. VLAN
allows preferred forwarding of voice data, for example. This functionality is important
for VoIP (IP telephony). This also means that phone calls can be made without interrup­tion with a restricted bandwidth.

Glossary

WAN

Wide Area Network

A WAN is a wide area network that is not restricted physically to a particular area, for
example the Internet. A WAN is run by one or more public providers to enable private
access. You access the Internet via an Internet service provider.

WDS

Wireless Distribution System

WDS describes the wireless connection between a number of access points.

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 router Gigaset 504 AGU com­plies with Standard 802.11g.

WPA

WPA is a standard-compliant solution for greater security in wireless networks. WPA is
meant to replace the existing WEP standard (Wired Equivalent Privacy) and offers more
reliable encryption and authentication methods.

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).
