ucts offer significantly reduced power consumption - for more energy-

efficient use, which helps make a cleaner environment for everyone.

You can turn the WLAN off completely when you're not using it. It's our

goal to ensure a sustainable economic process by using an environmentally friendly pro-

duction and management system - which makes it easy for us to meet the strict ISO

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.

uInternet 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.

uSetting 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.

– Using the router Gigaset 504 AGU makes it easy to set up a network at home or

in small offices. For example, users can exchange data or share resources in the

network, such as a file server or printer.

– The router Gigaset 504 AGU supports DHCP for dynamic IP configuration of the

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.

uSecurity 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.

6

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 block-

ing).

– 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.

uOffering 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.

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:

uOperate 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.

uA 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.

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

microwave ovens or the like. This may cause interference.

uPosition 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 perform-

ance. Make sure that the place where you position the router offers optimum recep-

tion throughout the house, apartment or office.

uMake sure the router cannot fall down, as this could damage the antenna. Position

the router on a non-slip surface.

uDo not place the router on any furniture surface that could be affected by the heat

from the device.

uLay the cables so that nobody can trip over them. You should not cover the cables

with anything.

Note:

Before the PCs can communicate with the router and with each other in a local net-

work, 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.

13

Installing the device

Connecting to the splitter data port

You can operate the router in two different operating modes in order to set up an Inter-

net connection:

– with an integrated ADSL modem

– with an external modem, such as a VDSL or cable modem

Using the integrated ADSL modem

ìConnect the ADSL port (grey) on the router to the ADSL socket on the splitter. To do

this, use the DSL cable supplied (grey).

Using UPnP (Universal Plug and Play)

PCs with UPnP (Universal Plug & Play) can offer their own network services and automat-

ically use services offered in the network.

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 automat-

ically 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.

ìIn the Advanced Settings menu, select: Internet – Internet Connection.

ìClick UPnP.

ìClick OK to apply the settings.

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 documen-

tation of your operating system.

Note:

When the UPnP function is active, system applications can assign and use Ports on a

PC. This poses a security risk.

Setting up the NAT function

The router Gigaset 504 AGU comes equipped with the NAT (Network Address Transla-

tion) 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 con-

text 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.

31

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.

32

Configuring Advanced Settings

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

uSet up the router as a virtual server by configuring Port Forwarding (page 32),

uOpen the firewall for a selected PC (page 34).

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.

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

ìSelect 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.

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.

33

Configuring Advanced Settings

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

ìSelect the required application from the Predefined Applications list.

ìSelect the checkbox in the Enabled column to activate the entry.

ìClick the Add button. The data for the required service is entered on the screen.

ìClick 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:

ìSelect the protocol for the service you are providing from the Protocol list.

ìUnder 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).

ìIn 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.

ìEnter 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.

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 net-

work and make it accessible to Internet users.

As the exposed host, the local client is directly visible to the Internet and therefore par-

ticularly 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 for-

warding) are not adequate. In this case you should take appropriate measures for the

clients concerned.

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

Exposed Host

ìEnter the Local IP Address of the PC that is to be enabled as an Exposed Host.

ìEnter a name for the PC in the Comment field.

ìActivate Enabled by ticking the check box.

ìClick 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.

ìClick the Delete button to delete the entry from the list.

ìApply the settings by clicking OK.

Note:

Only one PC per public IP address can be set up as an Exposed Host (see also Port For-

warding on page 32).

35

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 pro-

vider 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.

ìIn the Advanced Settings menu, select: Internet – Dynamic DNS

ìActivate the Dynamic DNS function.

ìSelect a provider from the Service provider list.

ìEnter Domain name, User name and Password. You will have received all the nec-

essary information when you registered with your Service provider.

ìClick OK to apply the settings.

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.

Configuring Advanced Settings

Qos (Quality of Service)

Many communication and multimedia applications require high speed and large band-

widths 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.

ìIn 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).

ìSelect 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.

ìSelect the Allocated bandwidth for Predefined applications.

ìClick 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.

ìIn 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.

ìIf 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.

ìAdjust 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).

38

Configuring Advanced Settings

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.

ìTo activate the DHCP server, select On.

ìIf 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.

ìDefine 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.

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

field.

ìApply 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 indi-

vidual PCs (e.g. when setting up these PCs for NAT functions).

ìEnter the MAC address of the PC to which you want to assign a static IP address.

ìEnter the IP address you wish to assign to the PC.

ìClick Add to add the entry to the list.

ìClick Delete to delete the entry from the list.

ìApply the settings by clicking OK.

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.

Note:

uIf 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.

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

PCs that use the network settings.

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.

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.

ìEnter 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.

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.

ìSelect Off to deactivate SSID broadcast.

To protect your wireless network, you should also enable encryption of data transmis-

sions (page 41).

Transmission mode

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).

ìSelect the required transmission mode for your wireless network.

Sending power

ìSelect 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 eaves-

drop on your wireless data transfer.

ìClick OK to apply the settings.

ponents 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.

ìIn the Advanced Settings menu select: Wireless Network – Encryption

their own authentication server. After a certain period of time (Rekey interval), encryp-

tion 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/

WPA2-PSK. Your device then automatically defines the best possible way to protect your

data for each client. The entries described below are identical for both options.

ìSelect the required option in the Security field.

ìEnter a key in the WPA shared key field (up to 32 characters) and confirm it by

entering it again. Use a combination of letters, digits and special characters.

Note:

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

encryption.

WEP encryption

If WPA is not supported by all components in your wireless network, we recommend

that you activate WEP Encryption on the components.

ìChoose the WEP option in the Security field.

ìSelect the Authentication type:

–Select Shared to require that each client log in to the network with a specified

key.

–Select Open to permit data transfer within the wireless network without the need

to enter a key.

You can choose either the standard 64-bit key or the more robust 128-bit key. The keys

are generated in hexadecimal or in ASCII format. You must use the same keys for encryp-

tion and decryption for the router and all your wireless network adapters.

ìSelect the Key length: 64 bits or 128 bits.

ìSelect the Input type, i.e. whether the key is to be entered manually or generated

automatically by means of a Passphrase.

Repeater function (WDS)

WDS (Wireless Distribution System) allows you to extend the range of your wireless net-

work 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 cli-

ents 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 automati-

cally set up a connection to the next access point / repeater (roaming). For security pur-

poses you must determine which access points / repeaters are to form a common wire-

less network.

If you want to use a repeater in your wireless network you must activate the Wireless

Distribution System (WDS) function.

ìIn the In the Advanced Settings menu select: Wireless Network – WDS Setting

ìTo 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 com-

pleted successfully the networks are displayed.

Note:

If you activate MAC access control, you must at least add the PC on which you are con-

figuring the router to the list. Otherwise, you will have no access to the user interface

and will receive an appropriate error message.

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

uYou can completely reset the router (page 10).

uYou 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.

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.

Local area networks with Gigaset products

You can use the router Gigaset 504 AGU to set up a local area network, for example a

home network. All PCs in this network can communicate with each other and have

access to the Internet.

There are various ways in which you can set up the network using a router Gigaset 504

AGU.

uSet up a wired local area network (Ethernet) and allow the connected PCs access to

the Internet (page 67).

uSet up a wireless local area network (WLAN) and allow the connected PCs access to

the Internet (page 68).

uSet up a local area network comprising wireless and wired network components

(page 70).

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 (Eth-

ernet).

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:

uInfrastructure mode

uAd-hoc mode

Infrastructure mode

Infrastructure mode connects wireless and wired networks with one another. In addi-

tion 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 communi-

cate 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 sta-

tions 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

uwirelessly networked PCs to the Internet and

uwirelessly 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

directly and wirelessly form the network on an "ad-hoc" basis, i.e. as and when required.

All the stations in the network have the same rights. Ad-hoc networks are used wher-

ever communications networks have to be set up quickly and there is no existing net-

work infrastructure, and where the participants are on the move.

69

Appendix

Linking wireless networks with the Internet

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

local area network to access the Internet simultaneously. To be able to use this function-

ality, you need a DSL connection obtainable from an Internet service provider. Find out

whether your service provider supports parallel access by several PCs.

Appendix

Linking a wireless network to an Ethernet

Wireless local area networks can work easily together with existing Ethernet networks.

If you wish to connect mobile stations to an existing wired network, you must group

together all mobile stations into a wireless local area network in infrastructure mode.

The devices of the 504 series have four Ethernet interfaces (LAN ports). Up to four PCs

can be directly connected to these LAN ports.

All PCs can access the Internet via the router Gigaset 504 AGU.

Please remember:

You can also connect an Ethernet router or switch to a LAN port to access a larger Eth-

ernet. If you want to link the Gigaset WLAN network to an existing network, a large

number of settings have to be applied. Therefore we cannot provide a general exam-

ple for this use; the configuration depends greatly on the networks in question. We

advise having the configuration of such a network carried out by a specialist.

Extending the wireless network coverage with a repeater

Using the Gigaset WLAN Repeater, you can extend your wireless network's coverage. Set

it up within the range of your network. The repeater will now transmit data traffic into

its own wireless area. This technology allows you to set up wireless networks that cover

a much larger area than is possible with a single router Gigaset 504 AGU.

PCs to be connected in a wireless local area network via a repeater must be equipped

with an integrated wireless network adapter or you have to connect an external wireless

network adapter (e.g. a USB adapter).

Glossary

Glossary

Access point

An access point, such as the router Gigaset 504 AGU, is the centre of a wireless local net-

work (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 Note-

books in a conference. All the network components are peers. They must have a wire-

less 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 con-

nect 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.

77

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 cli-

ent 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 appli-

cations 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 com-

ponents remain secure behind the firewall.

78

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

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 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

79

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 net-

works.

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

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 pro-

grams 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 iden-

tified 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:

uElectronic mail (e-mail)

uThe World Wide Web (WWW)

uFile transfer (FTP)

uDiscussion 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 com-

plex network (routing).

IP address

The IP address is the unique network-wide address of a network component in a net-

work 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 reg-

istered 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 net-

work component and a local network. The connection can be wired or wireless. An Eth-

ernet 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 net-

work 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 for-

mats, time frames and possibly troubleshooting. Communication between two applica-

tions 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 net-

work 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 tech-

nologies. For example, it can link a local network with Ethernet or WLAN technology to

the Internet.

See also: Bridge, Switch, Hub, Gateway

Server

A server makes a service available to other network components (Clients). The term

"server" is often used to refer to a computer or PC. However, it can also mean an appli-

cation that provides a particular service such as DNS, Web server, file server or print

server.

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 manage-

ment data and network management messages (known as traps) and reports the occur-

rence 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.

86

Glossary

SSID

Service Set Identifier

The SSID is used to identify the stations in a wireless network (WLAN). All wireless net-

work 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 con-

figuration. 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 compo-

nents. Unlike a hub however, the switch has its own intelligence that enables it to for-

ward packets to only the subnet or network component they are meant for.

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 in the network automatically.

URL

Universal Resource Locator

Globally unique address of a domain on the Internet.

VCI

Virtual Channel Identifier

Part of an address in an ATM network.

Virtual server

A virtual Server provides a service on the Internet that runs not on itself, but on another

network component. The router Gigaset 504 AGU can be configured as a virtual server.

It will then direct incoming calls for a service via Port forwarding directly to the appro-

priate 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 tech-

nical 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 interrup-

tion 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.

Web server

See Server

WEP

Wired Equivalent Privacy

WEP is a security protocol defined in the IEEE 802.11 standard. It is used to protect wire-

less 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 com-

plies 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 regu-

lar intervals by means of a keyword (pre-shared key). The key is updated after defined

periods (Rekey interval).
