Wired Local Network (Ethernet)
In a wired local network, PCs communicate with one another via an Ethernet cable.
When the Siemens Gigaset SX541 WLAN dsl is used, it establishes the connection
between the PCs. For this it has four Ethernet LAN ports for connecting four PCs. The
PCs have to be equipped with a network socket (Ethernet). New PCs frequently already
have this socket. For older PCs you need to install an Ethernet network card. The PC and
the Ethernet LAN socket on the Gigaset SX541 WLAN dsl are connected using an Ethernet cable (CAT5). One is supplied. You can obtain additional Ethernet cables from your
retailer.
The Gigaset SX541 WLAN dsl allows all PCs to access the Internet simultaneously.

Wireless Local Network (WLAN)
In a wireless local network (WLAN), PCs are linked without wires. The PCs have to be
equipped with a wireless network adapter (WLAN adapter) for this purpose, such as a
Gigaset PC Card or a USB Adapter.
We generally differentiate between 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
Gigaset SX541 WLAN dsl. The stations in the network always communicate via this
access point in infrastructure mode. Each station that wants to be part of the wireless
network must first register with the access point before it can exchange data.
The access point establishes the connection between the mobile stations of a wireless
network and a wired LAN (Ethernet) or the Internet. In this case, this is described as the
device's router functionality. The router sends data packets that are not addressed to stations within the network "outside" and forwards data packets originating from "outside"
to the appropriate station within the network.
You can use the Gigaset SX541 WLAN dsl to connect
u wirelessly networked PCs to the Internet and
u wirelessly networked PCs to an Ethernet network.
Infrastructure mode is the default configuration of the Gigaset SX541 WLAN dsl. This
configuration is described in the quick guide enclosed with the router.
Ad-hoc mode
An ad-hoc network is a wireless network set up without an access point or router. The
mobile network components that communicate with each other directly and without
wire connections form the network "ad-hoc", i.e. as and when required. All the stations
in the network have the same rights. Ad-hoc networks are used wherever communications networks have to be set up quickly and without any existing network infrastructure
and where the participants are on the move.

Linking wireless networks with the Internet
The Gigaset SX541 WLAN dsl has an ADSL interface that permits all stations within its
local network to access the Internet simultaneously. To be able to use this functionality,
you need a DSL or cable connection obtainable from an Internet provider. Find out
whether your Internet Service Provider supports parallel access by several PCs.

Linking a Wireless Network (WLAN) to an Ethernet (LAN)
Wireless network s 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 network in infrastructure mode.

Internet Telephony and Connecting Analogue Telephones
The Gigaset SX541 WLAN dsl allows fixed network and Internet telephony (VoIP) to be
combined via DSL for two analogue telephones.
With it you can optimally use the benefits of both technologies. Low priced Internet telephone rates can be availed of without the need for additional equipment. Additionally
you have the possibility to use your fixed network subsequently. As a result, you can use
the benefits of both technologies optimally. The particular type of telephony that is
most beneficial for you will depend on your telephony behaviour and on the particular
rate offered by your service provider. The Gigaset SX541 WLAN dsl gives you free choice
at any time.
Internet
Fixed Network
You can connect two arbitrary analogue telephones or base stations for cordless telephones to the telephone connections of your Gigaset SX541 WLAN dsl.
Please note that the Gigaset SX541 WLAN dsl is not intended to be directly connected
to ISDN. Connection is possible via an intermediate a/b converter or an ISDN telecommunications system (e. g. Gigaset SX353isdn).
To configure the Internet telephony you need the appropriate access data for your service provider.
You can of course operate Internet telephony later on via a PC connected to the Gigaset
SX541 WLAN dsl. In this case, the PC must be equipped with loudspeakers and microphone or headset and a full duplex sound card and must have the necessary software
installed.
Please note that telephone access via the Internet is only possible if an Internet connection is established.

Synchronising the TCP/IP Settings with the Gigaset SX541 WLAN dsl
You have now configured your PC so that it is ready to be connected to the Gigaset
SX541 WLAN dsl. You now have to release the old TCP/IP settings and synchronise them
with the settings of your Gigaset SX541 WLAN dsl.
ì Click Start – Run.
ì Ty pe WINIPCFG and click OK.
There may be a slight delay before the IP Configuration window appears.
ì Select your network adapter from the selection list.
ì Click Release and then on Update.
If the default IP address (192.168.2.1) of the Gigaset SX541 WLAN dsl was not
changed, the IP address should now read 192.168.2.x (with x being a number
between 2 and 255). The Subnet Mask must always be 255.255.255.0 and the
Standard Gateway must have the IP address of the Gigaset SX541 WLAN dsl

Configuring the Local Network
Checking the Connection to the Gigaset SX541 WLAN dsl
Once the network has been set up on your PC, you can check whether the PC is correctly
connected to the Gigaset SX541 WLAN dsl. This can be done as follows:
ì Open Command prompt. To do this, click Start – Programs – Command prompt.
ì Enter the command ping 192.168.2.1.
Please remember:
192.168.2.1 is the default IP address for the Gigaset SX541 WLAN dsl.
If the IP address was changed, enter the new IP address.
The ping command sends data packets to the Gigaset SX541 WLAN dsl with the specified IP address and checks whether the router responds. If this is the case, the command
presents statistics about the connection, for example how many data packets were sent,
how many were received, how long the transfer took, etc. If you can see this information, then the connection to the router is functioning properly.
If the command does not return any statistics, but ends with a time-out, this means that
the components cannot communicate with each other. Check the following points:
1. Is the Ethernet cable between the Gigaset SX541 WLAN dsl and the PC correctly connected or is there a wireless connection via a wireless network adapter?
The LED display for the LAN connections on the Gigaset SX541 WLAN dsl and link
display for the network card in your PC must be illuminated. For wireless connections, the Gigaset WLAN Adapter Monitor must display connection information.
2. Has TCP/IP been properly configured on your PC?
If the Gigaset SX541 WLAN dsl has the IP address 192.168.2.1, your PC's IP address
must be between 192.168.2.2 and 192.168.2.255. The default gateway must have
the address 192.168.2.1.
If you can successfully address the Gigaset SX541 WLAN dsl with the ping command,
then the PC has been configured correctly.

Security Settings
Setting Security Functions for the Wireless Network
In the next step you can set the encryption and authentication methods for your wireless network.
Wireless networks are even more strongly exposed to the risk of eavesdropping than
wired networks. With conventional network adapters an intruder only needs a device
with a WLAN adapter (for example a Notebook or a PDA (Personal Digital Assistant))
with an appropriately configured network card in order to eavesdrop on every communication made via a nearby wireless LAN.
The Gigaset SX541 WLAN dsl makes use of effective encryption methods to prevent
unauthorised eavesdropping as far as possible.
You can use the following security mechanisms:
u WPA2-PSK or WPA2-PSK / WPA-PSK (see page 63)
u WEP encryption (Wired Equivalent Privacy, see page 64)
We recommend using WPA2-PSK if it is supported by all components in your wireless
network.
You will find further options for setting data encryption and authentication in the
Advanced Settings menu (see page 97).
62
Page 65
Security Settings
WPA2 / WPA with Pre-Shared Key (PSK)
WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new standard WPA2 uses AES for the encryption.
WPA-PSK is a special WPA mode for users at home and in small companies without a
company authentication server. Encryption keys are automatically generated with the
Pre-shared Key, automatically changed ( "rekeying") and authenticated between the
devices after a certain period of time (Rekey Interval).
Please remember:
Every PC (network adapter) that requires access to a wireless network protected by
WPA must also support WPA. To find out whether and how you can use WPA on your
PC, read your network adapter's operating instructions.
ì Select the WPA2-PSK option if it is supported by all components in your wireless net-
work.
or
ì Select the WPA2-PSK / WPA-PSK option if some or all components in your wireless
network support WPA with the TKIP protocol.
ì Enter a key of your choice in the Pre-shared key field (min. 8 to max. 63 characters)
and confirm it by repeating the entry.
You must also set the same Pre-shared Key for all wirelessly connected PCs.
ì To go to the next step, click Next >.
63
Page 66
Security Settings
WEP Encryption
WEP (Wired Equivalent Privacy) is an encryption procedure for radio signals in wireless
networks and meets the IEEE 802.11 standard.
If you transmit data wirelessly and not all components in your wireless network support
the higher security standard WPA (see page 63), we recommend that you activate WEP-
Encryption for these network components.
You can choose either the standard 64-bit key or the more robust 128-bit key for encryption. The keys are generated in hexadecimal or in ASCII format. You must use the same
keys for encryption and decryption for the Gigaset SX541 WLAN dsl and all your wireless
network adapters.
ì Select the Key length: 64 bits or 128 bits.
ì Select the Input type, i.e. whether you wish to enter the key manually or have it
generated automatically by means of a Passphrase.
64
Page 67
Security Settings
Manual key entry
ì Select the Key type, Hex or ASCII.
.
If you select Hex, you can use the characters 0 to 9 and A to F.
– With a 64-bit encryption depth, the key is exactly 10 characters long.
– With a 128-bit encryption depth, the key is exactly 26 characters long.
If you select ASCII you can use the characters 0 to 9, A to Z and a to z plus the special
characters in the ASCII character set.
– With a 64-bit encryption depth, the key is exactly 5 characters long.
– With a 128-bit encryption depth, the key is exactly 13 characters long.
ì Confirm the key by entering it again in the Confirm key field.
Generating the key by means of a Passphrase
ì Enter a Passphrase (up to 32 characters) and confirm it by entering it again. The key
is generated automatically.
Please remember:
u It is very important that you make a note of the key or passphrase. You will need
this information to configure the wireless network adapters properly.
u When you have concluded the Security Setup Wizard, you must change the WEP
encryption on the wireless network adapters for the connected PCs in the same
way as they will not otherwise be given access to the Gigaset SX541 WLAN dsl's
wireless network.
ì To go to the next step in the Security Setup Wizard, click Next >.

Security Settings
Access Control Within the Wireless Network
you can specify which PCs will have wireless access to the Gigaset SX541 WLAN dsl and
hence to your LAN in this step. The access control is based on the MAC address of the
PCs' network adapters. You can enter the MAC addresses for the PCs manually or select
them from the list of PCs that are currently logged in.
The default setting for access control is disabled. This means that all PCs that use the
correct SSID can log in.
ì Next to MAC address filter select the option On to activate the MAC filtering.
Entering MAC addresses manually
ì Enter the MAC address of the network adapter. You will find this address on the bot-
tom of the device.
ì Enter the name of the PC.
ì Click the Add button to add the entry to the list.
Selecting from the list of logged-in PCs
ì Select the required PC from the Known wireless clients list. All PCs that are cur-
rently logged in to the router with the correct SSID are displayed.
ì Click the Add button to add the selected PC to the list.

Please remember:
If you activate MAC access control, you must at least enter the PC from which you
are configuring the Gigaset SX541 WLAN dsl. Otherwise you will no longer be able
to access the user interface and a corresponding error message will be shown.
If, by mistake, you have denied all PCs access to the Gigaset SX541 WLAN dsl, you
have two choices:
u You can completely reset the Gigaset SX541 WLAN dsl (see page 18).
u You can connect a PC to the Gigaset SX541 WLAN dsl using one of the LAN
connections (by cable). As MAC access control only applies to PCs that are connected "wirelessly", you can use this PC to change the configuration.
ì To go to the next step, click Next >.

Using UPnP (Universal Plug and Play)
PCs with UPnP (Universal Plug & Play) can offer their own network services and automatically use services offered on the network.
Please remember:
The PC must have Windows ME or Windows XP as its operating system. Check whether
the UPnP function has been installed in your PC's operating system. It may be necessary to retrospectively install the UPnP components even on Windows XP or Windows
ME systems. Please consult your PC's operating instructions.
As soon as you have installed UPnP in the operating system of a PC and activated it on
the router, applications on this PC (for example Microsoft Messenger) can communicate
via the Internet without your needing to expressly authorise it. In this case, the router
automatically implements port forwarding (Port Forwarding, see page 88), thereby
facilitating communication via the Internet.
You will see a symbol for your Gigaset SX541 WLAN dsl on the task bar on the PC on
which UPnP is installed. Windows XP systems will also include the icon under network
connections. Clicking on this icon opens the Gigaset SX541 WLAN dsl's configuration
screens.
ì In the Advanced Settings – Internet menu, select Internet Connection.
ì Select UPnP.
Please remember:
When the UPnP function is active, system applications can assign and use Ports on
a PC. This can be a security risk.

Firewall
The firewall functions of the Gigaset SX541 WLAN dsl include various security functions
for your local network.
You can:
u protect your network against hacker attacks (see below),
u block individual PCs' access to selected services or Internet sites (see page 81) or

ì In the Advanced Settings – Internet menu, select Firewall.
ì Select the required option.
ì Click OK to apply the settings.
Attack Detection
If the firewall functions of your Gigaset SX541 WLAN dsl are activated, the device monitors and limits the access of incoming traffic via the DSL connection with a function
called Stateful Packet Inspection (SPI). This allows the Gigaset SX541 WLAN dsl to identify and prevent certain types of attack from the Internet, such as Denial-of-Service
(DoS). DoS attacks are aimed at devices and networks with Internet connections. The
aim is not so much to steal data but to paralyse the computer or network to such an
extent that the network resources are no longer available. A typical hacker attack
involves making a remote computer announce that it is acting for the paralysed device,
for example, and receive the data meant for it.

Setting up the NAT Function
Your Gigaset SX541 WLAN dsl comes provided with the NAT (Network Address Translation) function. With Address Mapping, several users in your local network can access the
Internet via one or more public IP addresses. In the default setting, all the local IP
address are mapped to your router's public IP address.
One of the characteristics of NAT is that data from the Internet is not allowed into your
local network unless it has been explicitly requested by one of the PCs in that network.
Most Internet applications run behind the NAT firewall without any problems. If you
request Internet pages, for example, or send and receive e-mails, the request for data
from the Internet comes from a PC in the local network and so the router allows the data
through. The router opens exactly one port for the application. A port is an internal PC
address through which the data is exchanged between a server on the Internet and a
client on a PC in the local network. Communicating via a port follows the rules of a particular protocol (TCP or UDP).
If an external application tries to send a call to a PC within the local network, the router
will block it. There is no open port via which the data could enter the local network.
Some applications, such as games on the Internet, require several links, i.e. several ports
so that the players can communicate with each other. In addition, these applications
must also be permitted to send requests from other users on the Internet to the user in
the local network. These applications cannot work if Network Address Translation (NAT)
has been activated.
Using port forwarding (the forwarding of requests to particular ports) the router is
forced to forward requests from the Internet for a certain service, fro example a game,
to the appropriate port or ports on the PC on which the game is running.
Port triggering is a specific variant of port forwarding. Unlike port forwarding, in this
case the Gigaset SX541 WLAN dsl forwards data from the set port block to the PC that
has previously sent data to the Internet via a certain port (trigger port). This means that
approval for the data transfer is not tied to one specific PC in your network, rather to the
port numbers of the required Internet service.
Where configuration is concerned, this means:
u You have to define a so-called trigger port for the application and also the protocol
(TCP or UDP) that this port uses. You then assign the public ports that have to be
opened for the application to this trigger port.
u The router checks all outgoing data for the port number and protocol. If it recognises
a match of port and protocol to a defined trigger port, it will open the assigned public ports and note the IP address of the PC that sent the data. If data comes back from
the Internet via one of these public ports, it allows the data through and directs it to
the right PC. A trigger event always comes from a PC within the local network. If a
trigger port is addressed from outside, it is simply ignored by the router.
85
Page 88
Configuring the Advanced Settings
Please remember:
u An application that is configured for port triggering can only be run by one user in
the local network at a time.
u As long as the public ports are open, they can be used by unauthorised persons to
gain access to a PC in the local network.
When the Gigaset SX541 WLAN dsl is supplied, the NAT function (Network Address
Translation) is activated, i.e. all IP addresses of PCs in the local network are converted to
the router's public IP address when accessing the Internet.
You can use the NAT settings for the Gigaset SX541 WLAN dsl to
u set up port triggering for special applications (see page 87),
u set up the Gigaset SX541 WLAN dsl as a virtual server by configuring Port Forward-
ing (see page 88),
u open the firewall for selected PCs (see page 89).
Please remember:
You must make sure for the functions described below that the IP addresses of the
PCs do not change. If the IP addresses of the PCs are assigned via the DHCP server
of the Gigaset SX541 WLAN dsl, you must select the option Never expires
(see page 94) for the settings on the Local Network screen for Lease time or assign
static IP addresses for the PCs.
You can activate or deactivate the NAT function (default setting: NAT function is activated).
ì In the Advanced Settings – Internet menu, select Address Translation (NAT) and
select the required option.

Port Forwarding
If you configure Port Forwarding, the Gigaset SX541 WLAN dsl outwardly assumes the
role of the servers. It receives requests from remote users under its public IP address and
automatically redirects them to local PCs. The private IP addresses of the servers in the
local network remain protected.
Internet services are addressed via defined port numbers. The Gigaset SX541 WLAN dsl
needs a mapping table of the port numbers to redirect the service requests to the server
that actually provides the service. Port Forwarding has to be configured for this purpose.
ì To set up port forwarding for a service, select Port Forwarding in the
Address Translation (NAT) menu.
ì Select the required application from the Predefined applications list.
ì Select the option in the Enabled column.

Example: the Web server has been configured to react to requests on port 8080.
However, the requests from ripostes enter by po rt 80 (standard value). If yo u a dd th e
PC to the forwarding table and define port 80 as the public port and port 8080 as an

Opening the Firewall for Selected PCs (Exposed Host)
You can set up a client in your local network to be an exposed host. Your device will
them forward all incoming data traffic from the Internet to this client. You can then, for
example, operate your own Web server on one of the clients in your local network and
make it accessible to Internet users.
As the exposed host, your local client is directly visible to the Internet and therefore particularly expos ed to ris k (for example fro m hacker att acks). You sho uld only activate this
function if it is absolutely necessary (for example to operate a Web server) and other
functions (for example port forwarding) are not adequate. In this case you should take
appropriate measures on the clients concerned.
Please remember:
Only one PC per public IP address can be set up an Exposed Host (see also Section "Port

Dynamic DNS
Any service you provide on the Internet can be accessed by a Domain names. Your
router's Public IP address is assigned to this domain name. If your Internet Service Provider for your local network's WAN connection assigns the IP address dynamically, the IP
address of the router can change. The assignment to the domain name will no longer
be valid and your service will no longer be available.
In this case, you must ensure that the assignment of the IP address to the domain name
is updated regularly. This is handled by the dynamic DNS service (DynDNS). You can use
the DynDNS service to assign your Gigaset SX541 WLAN dsl an individual static domain
name on the Internet even if it does not have a static IP address.
There are various providers on the Internet offering a free DynDNS service.
The Gigaset SX541 WLAN dsl uses the DynDNS service from DynDNS.org

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.
ì In the Advanced Settings – Internet menu, select the entry QoS.
ì Select Differentiated services, i.e. the priorisation of certain services for data trans-
fer between your network and the Internet.
You can determine via Priority which data packets are to be given preferential transmission. With the aid of PHB (Per Hop Behaviours) a decision is also made about whether
data packets are to be forwarded immediately before all others (EF, Expedited Forward-
ing), guaranteed and without data loss (AF, Assured Forwarding) or normally (BE, Best
Effort). If your application already supports QoS, your application will determine the priority automatically and this will be noted by your device for forwarding. In addition, your
device recognises certain Predefined applications and gives each data packet the relevant priority. You can also determine which proportion of the bandwidth for your Internet connection is to be made available for a certain class as Allocated bandwidth.
ì Select the Allocated bandwidth for the Predefined applications and for the line
(all other applications).

PCs that have a wireless network adapter. In this case, eavesdroppers could use the SSID
to gain access to your network.
If you deactivate SSID broadcast, your Gigaset SX541 WLAN dsl's SSID will not be displayed. This increases the protection against unauthorised access to your wireless network. However, you must make a note of the SSID. You will need this to log on your PC.
ì Select the Off option to deactivate SSID broadcast.
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. For the best possible data transfer rates in your network select
IEEE 802.11g only. 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.

Setting Wireless Security
If you are sending data over wireless channels, we recommend that you activate encryption (WEP or WPA) on your wireless network components. WPA offers greater security
than WEP. We therefore recommend that you choose WPA encryption if it is supported
by all components in your wireless network.
WPA is a more advanced procedure than WEP for protecting wireless networks. Dynamic
keys based on TKIP (Temporal Key Integration Protocol) offer increased security. The
new WPA2 standard is based on AES.
WPA also supports the use of an authentication server.
ì In the Wireless Network menu, select Encryption & Authentication.
The following security mechanisms are currently available:
u WPA2-PSK and WPA2-PSK / WPA-PSK (see page 98)
u WAP2 and WPA2 / WPA with authentication server (see page 99)
u WEP encryption (Wired Equivalent Privacy) (see page 100)

WPA2-PSK and WPA2-PSK / WPA-PSK
WPA with Pre-shared Key (WPA-PSK)
WPA-PSK is a special WPA mode that provides encryption protection for users at home
and in small companies without a company authentication server. Encryption keys
are automatically generated with the Pre-shared Key and automatically changed (rekeying) and authenticated between the devices after a certain period of time (Rekey Inter-
val).
Which standard of encryption you can choose depends on the components in your wireless network. Every PC (network adapter) that requires access to a wireless network protected by WPA must also support WPA. To find out whether and how you can use WPA
on your PC, read your network adapter's operating instructions. If all components support WPA2, select option WPA2-PSK. If you are using network adapters that only sup-
port WPA, select the option WPA2-PSK / WPA-PSK. The entries described below are the
same for both options.
ì Select the required option in the Security field.
ì Enter a key in the Pre-shared key field (up to 32 alphanumerical characters) and
confirm it by entering it again.
ì Apply the settings by clicking OK.
