The Giga762SX WLAN dsl
The Siemens Giga762SX WLAN dsl is a powerful but simple communications device for
connecting your PC or local area network (LAN) to the Internet (via DSL). It contains an
integrated ADSL modem (ADSL /ADSL2+) enabling you to access the Internet easily.
You can connect your PC wirelessly to the Giga762SX WLAN dsl and create a wireless
local area network (WLAN). For network security, wireless transmission can be
encrypted using the WPA/WPA2 standard or 64/128-bit WEP.
The Giga762SX WLAN dsl also offers the functions of a PABX for Internet telephony
(VoIP) and fixed network telephony. You can connect up to two traditional analogue terminals and then use these analogue phones both to make calls via the Internet or also
via an existing analogue telephone line. In addition, you can operate SIP clients (wireless SIP telephones and PCs with appropriate software) as PABX extensions and therefore also make calls via the Internet or fixed network.
The Giga762SX WLAN dsl allows several users to access the Internet simultaneously. A
single user account can be shared if your Internet service provider permits this. If you
want to surf the Internet and make calls using the Internet at the lowest possible cost,
the Giga762SX WLAN dsl is a convenient and simple solution.
The Giga762SX WLAN dsl provides the new WPS function for wireless
connection of PCs or notebooks. You can activate this function via
the user interface or – depending on the hardware type of your
device – with the registration (Scan) button on the back panel. If the
other clients in your wireless network such as the Gigaset PC Card
300 also support WPS, you can connect with a simple click.

The Giga762SX WLAN dsl has an extensive range of functions but remains simple to use.
It can be configured and operational within a few minutes.
Note:
This user guide is based on the software release 2.3.
Do your part for the environment (ECO)
Thanks to a switch-mode power supply unit, all of our broadband products offer significantly reduced power consumption - for more energyefficient use. Each device also lets you variably reduce WLAN transmission power based on the size of your home or office network via the
user interface, which helps make a cleaner environment for everyone. You can even
turn the WLAN off completely when you're not using it. Some of our broadband products also offer you the convenience of switching the WLAN on or off with a handy button directly on the device itself - or have a timer do it for you. It's our goal to ensure a
sustainable economic process by using an environmentally friendly production and
management system - which makes it easy for us to meet the strict ISO 14001 standards
for international environmental management.

Wired local area network (Ethernet)
In a wired local area network, PCs communicate with one another via an Ethernet cable.
When the Siemens Giga762SX 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 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 Giga762SX WLAN dsl are connected using an Ethernet cable (CAT5). There
is one supplied. You can obtain additional Ethernet cables from your retailer.
The Giga762SX WLAN dsl allows all PCs to access the Internet simultaneously.

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 a Gigaset USB Adapter 54.
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
Giga762SX WLAN dsl. 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 Giga762SX 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 for the Giga762SX WLAN dsl.
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 wherever communications networks have to be set up quickly and there is no existing network infrastructure, and where the participants are on the move.

Linking wireless networks with the Internet
The Giga762SX WLAN dsl has an ADSL interface that permits all stations within its local
area network to access the Internet simultaneously. To be able to use this functionality,

Ethernet
(wired)
The Giga762SX WLAN dsl has four Ethernet interfaces (LAN ports). Up to four PCs can
be connected directly to these LAN ports.
All PCs can access the Internet via the Giga762SX WLAN dsl.
Please remember:
You can also connect an Ethernet router or switch to a LAN port to access a larger Ethernet. 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 example 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 Giga762SX WLAN dsl.

Internet telephony and connecting analogue phones
The Giga762SX WLAN dsl allows a combination of analogue fixed network telephony
and Internet telephony (VoIP) over DSL for two analogue telephones and four other
wired or wireless VoIP telephones or SIP clients.
This provides you with the full benefits of both technologies. You can make use of the
low-cost call rates of Internet telephony without any additional equipment. In addition,
you have the option of using your analogue fixed network connection. The type of calls
that are cheaper for you will depend on what calls you make and when you make them,
and the rates offered by your service provider. The Giga762SX WLAN dsl gives you complete freedom of choice at any time.

Internet
Fixed network
You can choose whether to connect any two analogue phones, a fax machine or an
answering machine to the phone ports. You can configure these ports using the
Giga762SX WLAN dsl.
The PABX of the Giga762SX WLAN dsl allows you to connect wireless SIP phones (WLAN
handsets) and PCs with SIP clients (software for Internet telephony) as extensions. You
can use all functions of your PABX for Internet telephony also.
You will need the relevant access data for your VoIP provider to configure Internet
telephony.
Please remember:
You can only be reached via the Internet (VoIP) when an active Internet connection
is established. You can still be called any time via the fixed network, however.
WPS
Wi-Fi Protected Setup (WPS) makes it easier to establish and encrypt a wireless network (1 click only). You no longer need to configure and synchronise the individual
components of your wireless network manually.
A wireless network is assigned a name (SSID) and requires the encryption of data traffic
to protect against the risk of unauthorised access. The access point requires authentication with an SSID and - if encryption is activated - a key to allow a WLAN adapter to
access services.
WPS uses the encryption methods WPA-PSK or WPA2-PSK. Devices
with WPS can automatically synchronise each other. The predefined
individual SSID and pre-shared key is used for encryption.
WPS is not possible in networks that use WEP encryption or WPA2/
WPA authentication. WPS may be used without encryption.
Clients without WPS can be connected manually.

The Giga762SX WLAN dsl
WPS provides two possibilities for registration:
u Via registration button
The access point (e.g. the Giga762SX WLAN dsl) has a registration button. The reg-
istration button is available either:
– as hardware: a specific button (labelled Scan) is provided on the device’s back
panel.
– as software: registration can be started via the WPS Registration page of the
user interface.
In the description that follows, the term registration button refers to both the Scan
button and the corresponding function in the user interface.
Depending on your hardware version, WPS registration may only be possible via the
user interface.
Once the registration button has been activated, the device allows the registration
of a WLAN client (repeater or wireless network adapter) during a two-minute inter-
val.

software
The first time this button is pressed, the device automatically creates a SSID and a
pre-shared key, if these had not been already set on delivery or has been configured
before manually. If a client activates WPS registration within the two-minute inter-
val, the security data is exchanged and a connection is established. Only one client
may synchronise during the two-minute interval. After the successful synchroniza-
tion the registration is closed.
The automatically or manually created security data is valid for all further WPS reg-
istration processes. If you change this security data again manually or after a factory
reset the clients have to be registered again.
u Via Personal Identification Number (PIN)
The PIN offers improved security for registration. No other device (e.g. in an adjacent
room) can log in unnoticed. A PIN is used for registration which must be identical on
both devices. If a client logs in with this PIN, the security data is synchronised. Usu-
ally the th PIN of the access point is used. For security reasons a new PIN can be cre-
ated.
It is also possible to create the PIN on one of the clients.

Features and applications
The Giga762SX WLAN dsl'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 Giga762SX WLAN dsl allows several users to have Internet access via the inte-
grated ADSL /ADSL2+ modem.
– Since many DSL providers permit communication with end users via the PPPoE
protocol, the Giga762SX WLAN dsl has an integrated Client for this protocol, so
you no longer have to install this service on your PC.
– The Giga762SX WLAN dsl supports shared Internet access for up to 252 users.
This means several users in your network can surf the Internet at the same time,
all using the same Internet account.
u Setting up a local area network
The Giga762SX WLAN dsl offers the following possibilities:
– 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 Giga762SX WLAN dsl makes it easy to set up a net-
work at home or in small offices. For example, users can
exchange data or share resources in the network, such as a file
17
Page 16
The Giga762SX WLAN dsl
server or printer. You can connect a USB hard disk or a printer to the USB interface
of the Giga762SX WLAN dsl and make them available to all users in your network.
The Giga762SX WLAN dsl supports DHCP for dynamic IP configuration of the local
area network, and DNS for domain name mapping.
u Connecting phones and Internet telephony
The Giga762SX WLAN dsl permits
– Internet telephony via the DSL port.
– Fixed network telephony via the analogue port.
– Connection of two analogue phones for Internet telephony and for fixed network
calls as well as connection of wireless SIP phones and PCs with SIP clients for
Internet telephony.
– Connection of an answering machine or fax.
Data transfer for VoIP is handled by the SIP protocol with high connection and voice
quality. If the Internet connection has been interrupted or you do not want to make
a call via VoIP, you can simply make a call via the fixed network (if a fixed network
phone is connected).
u Security functions
The Giga762SX WLAN dsl offers comprehensive security measures:
– Firewall protection against unauthorised access from the Internet
All PCs in the local area network use the Public IP address of the Giga762SX WLAN
dsl for their Internet connections, which makes them 'invisible' on the Internet.
The Giga762SX WLAN dsl only allows access from the Internet if this has been
requested from within the local area network.
With the firewall, the Giga762SX WLAN dsl also offers comprehensive protection
against hacker attacks.
– Service filtering
The Giga762SX WLAN dsl can filter Internet access. Here you determine which
PCs may access which Internet services.
– Access control and encryption for the local area network
The Giga762SX WLAN dsl is delivered with a predefined individual encryption
(WPA2-PSK/WPA-PSK with pre-shared key). You will find the corresponding infor-
mation at the label on the devices bottom. So, your wirless network is protected
against unauthorised access.
If there are wireless network adapters of your PCs which do not support this
encryption method, you can use other encryption methods and authentication
methods (WEP, WPA/WPA2, 802.1x) to prevent unauthorised access to your wire-
less LAN or to make data illegible to unauthorised parties.
With MAC access control you can allow wireless access to selected PCs.
18
Page 17
The Giga762SX WLAN dsl
u Offering your own services on the Internet
– If you want to offer your own services on the Internet, you can set up the
Giga762SX WLAN dsl 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.
u Providing an HTTP or FTP server via USB interface
– You can easily establish an FTP or an HTTP server for Internet access with the
Giga762SX WLAN dsl.
– You can connect a USB hub to the USB port on your Giga762SX WLAN dsl and
thereby at the same time provide a printer and a storage medium for all clients in
your local area network.

For additional WPS registration options see chapter "WPS Registration" on page 48.
For the wireless connection of additional PCs without WPS function see page 36.
Wireless without WPS
A wireless connection is made using a wireless network adapter that must be installed
in your PC. This can be an 802.11g or 802.11b-compatible wireless network adapter.
Owing to the superior range and the high data throughput, we recommend that you use
the Gigaset PC Card 54 or the Gigaset USB Adapter 54.
A wireless network is defined by assigning an identical SSID to all the devices.
ì You should therefore enter the SSID for the Giga762SX WLAN dsl in your network
adapter configuration. The default SSID for the Giga762SX WLAN
dsl is shown at the label on the bottom of the device.
If you use a wireless network adapter from the Gigaset range,
enter the SSID using the Gigaset WLAN Adapter Monitor.
The Giga762SX WLAN dsl is delivered with preset individual encryption ( WPA2-PSK/ WPA -PSK wi th pre-sh ared Key). You wi ll find thi s key
at the label on the devices bottom.

WPS Registration
Wi-Fi Protected Setup (WPS) makes it easier to establish a wireless network. Devices
equipped with WPS can create and synchronise an SSID and a WPA key (pre-shared key)
automatically. These security data can be created in different ways:
– They are generated automatically on initial WPS registration.
– They have been previously configured manually.
– The device has been delivered with preset security data.
All you need to do to establish a secure wireless connection is
u for devices with hardware button – to press the registration (or Scan) button on the
access point and on the client or
u for devices without hardware button – to activate the WPS registration in the user
interface of the access point and the client.
For further information, see "WPS" on page 15.
48
Page 47
Basic Setup Wizard
ì Click Register to start WPS registration.
This function corresponds to pressing the Scan button on the device’s back panel.
Once WPS registration is activated, the device searches for a WPS client within range.
Any WPS client within range that activates the WPS function during the two-minute
interval receives the Giga762SX WLAN dsl security data (SSID and pre-shared key)
and is thereby registered.
The registration progress is shown in the window.
You can repeat these steps for each WLAN client to be registered.
Only one client may register during the two-minute interval. If two clients try to regsister at the same time, the registration will be broken down and an error message
appears.

Assigning a password
In the first step of the configuration you can change the password for the user interface.
When the device is supplied, the configuration of your Giga762SX WLAN dsl is protected
with the admin password. To prevent unauthorised changes to the configuration, you
should change the password at regular intervals.
ì Enter the old password in the Current password field.
ì Enter the new password in the New password field and repeat the entry in the
Confirm new password field.
The password may contain up to 20 characters. Note case sensitivity. Avoid proper
names and all too obvious words. Use a combination of letters, digits and special
characters.
Note:
If you ever forget your password you will have to return the Giga762SX WLAN dsl to
its factory settings (page 127). Please bear in mind that this will restore all settings to
the factory configuration. The password will again be admin.
ì To go to the next step, click Next >

Page 51
Security Setup Wizard
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 Giga762SX WLAN dsl is shown at the label on the bottom of the
device. For security reasons you can change this SSID and deactivate SSID broadcast. If
this option is enabled, the Giga762SX WLAN dsl will send the SSID in all data transfers
and the SSID of the Giga762SX WLAN dsl will be displayed on PCs that have a wireless
network adapter. In this case, unauthorised persons could use the SSID to gain access to
your network.
If you have performed a successful WPS registration before a manual configuration of
security data, this page shows the generated SSID. Make a note of this SSID. You will
need it to manually configure the wireless network adapters that do not support WPS.
ì If you are using WPS registration, click on Next >.
ì Enter a character string of your choice in the SSID field. 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 the new SSID has also been entered.
ì Deactivate SSID broadcast and make a note of the SSID. You will
need for further wireless connections to the Giga762SX WLAN
dsl.
ì Click Next >.

Security Setup Wizard
Setting up security functions for the wireless network
Wireless networks are even more susceptible to eavesdropping than wired networks.
With conventional network adapters, an intruder only needs a device with a WLAN
adapter (e.g. a notebook or a PDA [Personal Digital Assistant]) with an appropriately
configured network card in order to eavesdrop on every communication made via a
nearby wireless LAN.
The Giga762SX WLAN dsl makes use of effective encryption methods to prevent unauthorised eavesdropping as far as possible.
The Giga762SX WLAN dsl is delivered with preset individual encryption (WPA2-PSK/
WPA-PSK with pre-shared Key). You will find this key at the label on the devices bottom.
If all components of your wireless network provide this encryption method there is no
need of any settings in this screen. If not, or if you want to change the preset key (e. g.
if unauthorised persons may have access to your device), you can configure the encryption for your wireless network in the next step.
You can use the following security mechanisms:
u WPA2-PSK, WPA-PSK or WPA2-PSK/WPA-PSK (page 54)
u WEP encryption (Wired Equivalent Privacy, see page 56)
You will find further options for setting up data encryption and authentication in the
Advanced Settings menu (page 87).
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 Integrity Protocol), offer increased security. The new
standard WPA2 uses AES (Advanced Encryption Standard) for encryption.
54
Page 53
Security Setup Wizard
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.
Note:
Every PC (network adapter) that requires access to a WPA-protected wireless network
must also support WPA. Information about this can be found in the operating manual
for your network adapter.
This page shows the preset encryption settings.
ì If you do not want to change the encryption settings, click on Next >.
If you yo want to change the pre-shared key:
ì Select WPA2-PSK if WPA2 is supported by all components in the wireless network.
ì Select WPA-PSK only if WPA is supported by all components in the wireless network.
ì Select WPA2-PSK / WPA-PSK if only some components in the wireless network sup-
port WPA.
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 set up the same pre-shared key for
all wirelessly connected PCs. Use a combination of letters, digits and special characters.
ì By clicking the Unmask button, a message showing the pre-
shared key is output in readable characters.
ì To go to the next step, click Next >
55
Page 54
Security Setup Wizard
WEP encryption
WEP (Wired Equivalent Privacy) is an encryption 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 (page 55), we recommend that you activate WEP
Encryption.
WEP encryption and WPS registration cannot be used together in a wireless network.
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 encryption and decryption for the Giga762SX 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 the key is to be entered manually or generated
automatically by means of a Passphrase.
Manual key entry
ì Select the Key type, Hex or ASCII.
If you select Hex as the key type you can use the characters 0 to 9 and A to F.
– With a 64-bit encryption depth, the key is 10 characters long.
– With a 128-bit encryption depth, the key is 26 characters long.
If you select ASCII as the key type, you can use the characters 0 to 9, A to Z, a to z
plus the special characters in the ASCII character set.
– With a 64-bit encryption depth, the key is 5 characters long.
– With a 128-bit encryption depth, the key is 13 characters long.
56

Security Setup Wizard
ì Confirm the key by entering it again in the Confirm key field.
Generating a 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.
Note:
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 You have to change the WEP encryption in the wireless network adapters for the
connected PCs in the same way, otherwise they will not be given access to the
Giga762SX WLAN dsl wireless network.

Access control within the wireless network
In this step you can specify which PCs will have wireless access to the Giga762SX WLAN
dsl and hence to the LAN. Access control is based on the MAC address of the PC network
adapters. You can enter the MAC addresses for the PCs manually or select these from the
list of PCs that are currently logged in.
Access control is disabled by default. This means that all PCs that use the correct SSID
can be logged in.
ì Next to the MAC address filter, select On to activate the MAC filter.
Entering MAC addresses manually
ì Enter the MAC address of the network adapter. You will find this address on the
underside 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 were
already entered manually on the router with the MAC address are displayed.
ì Click the Add button to add the selected PC to the list.
58
Page 57

Note:
If you activate MAC access control, you must at least add the PC on which you are configuring the Giga762SX WLAN dsl to the list. Otherwise, you will have no access to the
user interface and will receive an appropriate error message.
WPS registration is only possible for PCs in the list if you have activated MAC access
control.
If you have inadvertently denied all PCs access to the Giga762SX WLAN dsl, you have
two options:
u You can completely reset the Giga762SX WLAN dsl (page 26).
u You can connect a PC to the Giga762SX WLAN dsl using one of the LAN connec-
tions (by cable). As MAC access control only affects 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 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 operating
instructions of your PC.
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 (Port forwarding, see page 76), thereby facilitating
communication via the Internet.
The task bar on the PC on which UPnP is installed contains an icon for the Giga762SX
WLAN dsl. 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

Attack Detection
If the firewall functions of the Giga762SX WLAN dsl are activated, the device monitors
and limits access to incoming data traffic via the DSL connection with a function called
"Stateful Packet Inspection" (SPI). This allows the Giga762SX WLAN dsl to detect 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 as to paralyse the computer or network to such an extent that the
network resources are no longer available. A typical hacker attack involves, for example,
a remote computer acting in place of the paralysed device and receiving the data
intended for the device.
You can use the Attack Detection function to change the standard firewall settings.
ì In the Advanced Settings menu, select: Internet – Firewall – Attack Detection
ì Select the security level for the firewall:

Setting up the NAT function
The Giga762SX WLAN dsl 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.
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.
Port triggering is a special variant of port forwarding. Unlike port forwarding, the
Giga762SX WLAN dsl forwards the data from the port block to the PC which has previously sent data to the Internet via a certain port (trigger port). This means that approval
for the data transfer is not tied to one specific PC in the 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 are 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 identifies
a match of port and protocol for a defined trigger port, then it will open the assigned
public ports and notes the IP address of the PC that sent the data. If dat a comes back
from the Internet via one of these public ports, the router allows
it through and directs it to the appropriate PC. A trigger event
always comes from a PC within the local network. If a trigger port
is addressed from outside, the router simply ignores it.
73
Page 72
Configuring Advanced Settings
Note:
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 Giga762SX 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 to configure the Giga762SX WLAN dsl to carry out the following tasks:
u Set up port triggering for special applications (page 75),
u Set up the Giga762SX WLAN dsl as a virtual server by configuring Port Forwarding
(page 76),
u Open the firewall for a selected PC (page 78).
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
Giga762SX WLAN dsl, you must select Never expires (page 83) 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.

Port Forwarding
If you configure Port Forwarding, the Giga762SX WLAN dsl 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.
76
Page 75

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 76).

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 Giga762SX WLAN dsl 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.
79
Page 78
Configuring Advanced Settings
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.

Defining the private IP address for the Giga762SX WLAN dsl
On this screen you can change the device's IP address. The preset IP address is 10.0.0.2.
This is the Private IP address of the Giga762SX WLAN dsl. 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 Giga762SX WLAN dsl can be
reached from outside is assigned by the Internet service provider. The default Subnet
mask for the local network administered by the Giga762SX WLAN dsl is 255.255.255.0.
ì If you want to assign a different IP address to the Giga762SX WLAN dsl, 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).
82
Page 81
Configuring Advanced Settings
We recommend that you use an address from a block that is reserved for private use.
This address block is 10.0.0.1 to 10.255.255.254.
ì Adjust the Subnet mask if necessary.
The Subnet mask specifies how many address parts of the IP address must be identical for all network components (including routers).
Notes:
New settings can only be made after the Giga762SX WLAN dsl 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 Giga762SX WLAN dsl has a DHCP server for which the factory setting is active. Consequently, the IP addresses of the PCs are automatically assigned by the Giga762SX
WLAN dsl.
Note:
u If the DHCP server for the Giga762SX WLAN dsl is activated, you can configure the
network setting 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 Giga762SX WLAN dsl should use to automati-
cally assign IP addresses to the PCs. Define the First issued IP address and the Last
issued IP address.
ì If you want to define a different Default gateway in your local area network instead
of the Giga762SX WLAN dsl, enter the IP address of this default gateways in the relevant boxes.
Entering the DNS server
DNS is a decentralised service that assigns PC names or Internet

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 Giga762SX WLAN dsl is shown at the label on the bottom of the
device. For security reasons you can change this SSID and deactivate SSID broadcast (for
information see below).
Note:
If a WPS registration (see page 48) was performed before manual configuration, you
should not change this SSID here manually. Otherwise, the registered clients will no
longer have access to your wireless network.
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 (default setting), the Giga762SX WLAN dsl will send the SSID in
all data transfers and the SSID of the Giga762SX WLAN dsl will be displayed on PCs that
have a wireless network adapter. In this case, hackers could use the SSID to detect your
network.
If you deactivate SSID broadcast, the SSID of the Giga762SX WLAN dsl 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.
To protect your wireless network, you should also enable encryption of data transmissions (page 87).
ì Select Off to deactivate SSID broadcast.

receives the Giga762SX WLAN dsl security data (SSID and pre-shared key) and is
thereby registered.
The registration progress is shown in the window.
You can also follow the registration process via the LED display (see page 33).
If more than one client tries to register within the two minutes, an error message
is displayed. You may retry the WPS registration after a short time.
If an external client succeeds in registering, the LED (see page 33) displays a suc-
cessful WPS registration. The desired client in you network, however, has no con-
nection to the Giga762SX WLAN dsl and displays a registration failure. In this case
you should change the pre-shared key (WPA2-PSK/WPA-PSK) as soon as possible
and then perform WPS registration via PIN (see below).
–Send own PIN
An automatically generated PIN is shown.
If you want to create a new PIN, click Generate PIN.
Click OK to activate your settings.
Enter the generated PIN on all WLAN partner devices that are to establish a
connection.
– Enter partner device PIN
You would use this option if you have created a PIN at the desired client. Enter the
PIN of the WLAN partner device and click OK to activate your settings.
Note:
If you have activated access control via the MAC address filter, you have to include the
clients in the MAC address list before registering via WPS (see page 95).
Setting encryption
Note:
The Giga762SX WLAN dsl is delivered with preset individual encryption (WPA2-PSK/
WPA-PSK with pre-shared key). You should change this settings only, if not all components of your wireless network provide this encryption method, or if you want to
change the preset key for security reasons, or if you want to use the WDS repeater
function.
If you change the preset key after having registered PCs at the Giga762SX WLAN dsl
via WPS or manually, you must register all PCs again manually or via WPS.
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 also supports the use of an authentication server.

WPA with a 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.
Select WPA2-PSK / WPA-PSK if both methods are used in your network. 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.
ì Select the required option in the Security field.
ì Enter a key in the Pre-shared key field (up to 32 characters) and confirm it by enter-
ing it again. Use a combination of letters, digits and special characters.
ì By clicking the Unmask button, a message showing the pre-shared key is output in
readable characters.
ì Apply the settings by clicking OK.
WPA and WPA2 with authentication server
In large networks (e.g. in companies) WPA enables the use of an additional authentication service. In this case, user access is controlled by user accounts and passwords, in
addition to WPA encryption. A RADIUS server acts as an authentication server. You can
select the new WPA2 standard if it is supported by all components in your wireless net-
work. Select WPA2 / WPA if you are using devices that only support WPA.

ventions of the RADIUS servers that the server is to use for authentication.
ì Click OK to apply the settings.

WEP encryption
If WPA is not supported by all components in your wireless network, we recommend
that you activate WEP Encryption on the components.
Note:
You cannot use WEP together with WPS.
ì Choose the WEP option in the Security field.
ì Select 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 encryption and decryption for the Giga762SX WLAN dsl and all your wireless network adapters.
ì Select the Key length: 64 bits or 128 bits.

Note:
If you activate MAC access control, you must at least add the PC on which you are configuring the Giga762SX WLAN dsl to the list. Other wise, 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 Giga762SX WLAN dsl, you have
two options:
u You can completely reset the Giga762SX WLAN dsl (page 26).
u You can connect a PC to the Giga762SX WLAN dsl using one of the LAN connec-
tions. 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
inforamation refer to the section "Setting encryption" on page 88.
ì In the Advanced Settings menu, select: Wireless Network – Repeater (WDS)
ì To activate WDS select the On option next to Wireless distribution system.
The environment is scanned for wireless networks in range. 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
– Ty pe (11b or 11g)
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.
ì Select the Active check box to register a repeater to your wireless network.
Note:

Note:
u WDS can only be used with WEP encryption or without encryption. You may have to
change the encryption of your wireless network, if applicable.
u The encryption settings on the repeater have to correspond to the settings on your
Giga762SX WLAN dsl.
u The Giga762SX WLAN dsl and the repeaters must use the same channel.
Further information can be found in the user manual for the repeater.
Setting up Internet telephony (VoIP)
The Giga762SX WLAN dsl allows you to make telephone calls via the Internet using an
analogue telephone and also via the fixed network as usual. For Internet telephony
(VoIP), you require access authorisation from your service provider and the relevant
access data. To make calls, you have to enter this data along with other configuration
settings under Advanced Settings in the Teleph ony - VoIP menu.
You can connect a base station for handsets or fax machines to the two telephone ports
of the Giga762SX WLAN dsl analogue phone. In addition, you can set up additional
extensions for Internet and fixed network calls using SIP clients (as WL AN handsets or in
wired or wireless mode on PCs).
The menu comprises the following functions:
VoIP Enter the basic data from your service provider here (page 99).
Extensions Set up the functions for internal extensions here (page 102).
Dialing Plans Specify numbers here that are to be dialled only via the fixed network
or only via the Internet. You can also enter a call-by-call provider for the
fixed network (page 106).
Define an area code (page 106).
Quick Dial Specify speed dial numbers or names here for phone numbers you use
frequently (see page 107)
Note:
If you do not specify any of your own dialling plans, then the default settings will be
used as entered in the Teleph ony menu under Dialing Plans. Emergency numbers
are directed via the fixed network, while all other calls are made via the Internet.
Important information:
u You cannot make calls if there is a power failure, even the emergency numbers are
not accessible then.
u If VoIP is not set up, you will always make calls via the fixed network. The dialling
plans will not apply in this case (page 106).
u Check these dialling plans (page 106) and change them if you have agreed special
phone tariffs with another provider.
u Do not change the default setting for the Internet connection mode (= "permanent
connection") if you are using VoIP (page 44). You can only be called via VoIP if this
setting is used. Remember, though, that this setting can result in high connection
costs if you have agreed a time-based tariff with your Internet service provider.

Extensions
Your Giga762SX WLAN dsl allows you to configure up to six internal extensions that you
can use for making calls via the fixed network or via VoIP. Two of these extensions are
connected to your Giga762SX WLAN dsl via the Phone 1 and Phone 2 ports, while the
remaining extensions are connections for SIP clients. You can assign each extension the
relevant line (fixed network or VoIP account) for incoming and outgoing calls and make
other settings for each extension (e.g. call waiting, call forwarding, caller display).
The process for configuring extensions, which use the two telephone ports of the
Giga762SX WLAN dsl, is somewhat different to that for the SIP extensions. The latter
must be VoIP telephones, which are connected in wired or wireless mode to the
Giga762SX WLAN dsl, or PCs with a SIP client, which are connected to the Giga762SX
WLAN dsl.
