Checking the Connection to the Gigaset SX551 WLAN dsl
Once the network has been set up on your PC, you can check whether the PC is correctly connected to the Gigaset SX551 WLAN dsl. This can be done as follows:
Open Command prompt. To do this, click Start Programs Command prompt. Enter the command ping 192.168.2.1.
Please remember: 192.168.2.1 is the default IP address for the Gigaset SX551 WLAN dsl. If the IP address was changed, enter the new IP address. The ping command sends data packets to the Gigaset SX551 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 SX551 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 SX551 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 SX551 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 SX551 WLAN dsl with the ping command, then the PC has been configured correctly.

Select Always on if the connection is to exist at all times when the Gigaset SX551 WLAN dsl is switched on. Please remember: This option can result in high connection charges if you have a time-based tariff. Select Connect on demand if applications such as a Web browser or an e-mail program are to connect to the Internet automatically. In the Idle time before disconnect field, enter a period of time after which the Internet connection is to be automatically ended if no data is transmitted (default setting: 3 minutes). You can deactivate this function by entering "0". This means that the connection will continue to exist even if no data is transmitted. If you have a time-based tariff this can cause high charges. In this case you should enter a value other than "0". This time setting only applies to the Connect on request option. Select Connect manually if you always want to establish and end the connection to the Internet manually. If you have a time-based tariff this will save you high connection charges. How to establish a connection manually is described on page 124. Please remember: You must set the option Always on if you want to operate Internet telephony. PPPoE pass-through PPPoE pass-through enables you to use an additional Internet connection (with another service provider) from one PC. You can find detailed information about this on page 75.
Deactivate PPPoE pass-through if you do not wish to use this function. When you have entered the data, 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. You can find detailed information about this on page 72.
Activate UPnP if you wish to use this function. Click Next >.

Telephony

You will find the access data you need for configuring the Internet telephony (VoIP) in the documentation received from your service provider.
Select On for VoIP account, if you want to use Internet telephony (default setting). Select Other from the Service provider selection menu (default setting).

LAN Configuration

You can use the LAN configuration to define an IP address for the Gigaset SX551 WLAN dsl and configure the DHCP server.
Select Advanced Settings Local Network.
Defining the private IP address for the Gigaset SX551 WLAN dsl You can change the device's IP address on this screen. The preset IP address is 192.168.2.1. This is the Private IP address of the Gigaset SX551 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 Gigaset SX551 WLAN dsl can be reached from outside is assigned by the Internet service provider.
If you want to assign the Gigaset SX551 WLAN dsl a different IP address, enter it in
the fields next to IP address.
Select a number from the Subnet mask list.
We recommend using an address from a block that is reserved for private use. This address block is 192.168.1.1 192.168.255.254. Please remember: New settings can only be made after rebooting the Gigaset SX551 WLAN dsl. 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 Gigaset SX551 WLAN dsl has a DHCP Server for which the factory setting is active. As a result, the IP addresses of the PCs are automatically assigned by the Gigaset SX551 WLAN dsl. Please remember: u If the DHCP server for the Gigaset SX551 WLAN dsl is activated, you can configure the network setting on the PC so that the Obtain an IP address automatically option is set. To find out how to do this, please read Section "Configuring the Local Network" on page 22.
u If you deactivate the DHCP server, you will have to assign a static IP address for the
PCs using the network settings.
To activate the DHCP server, select On. If the DHCP server is active, you can define a Lease time. The Lease time determines
the period for which the PCs keep the IP address assigned to them without changing them. Please remember: If you select the Never expires option, the IP addresses are never changed. You should select this option if you want to make NAT or firewall settings using the IP addresses of the PCs; otherwise you have to assign these PCs static IP addresses.
Define the range of IP addresses that the Gigaset SX551 WLAN dsl should use to
automatically assign IP addresses to PCs. Define the First issued IP address and the Last issued IP address. field.
You can define the name of a domain (Windows workgroup) in the Domain name
Assigning Static IP Addresses to Individual PCs
Even if you have activated the DHCP server, you can still assign individual PCs a static IP address (for example if you are setting up these PCs for NAT functions).

or only via the Internet. You can block numbers completely (for example 0190 numbers) or enter a call-by-call provider for the fixed network (see page 109). Please remember: If you do not specify any of your own dialing rules, then the default settings will be used as entered on the Dialing Plans screen in the VoIP menu. All other calls are made via the Internet. If you press the * key twice before dialing the number on the phone, then the call will always be made via the fixed network. The dialing rules will not apply in this case. Switching over takes a little time. For automatic dialing, insert a pause after the ** by pressing the recall key. You should therefore press: * key, * key, recall key and then the keys for the required phone number.
u Quick dial: Specify quick dial numbers or terms here for phone numbers you use fre-

quently (see page 111).

Important information:
u If VoIP is not set, you will always make calls via the fixed network and the dialing
rules (see page 109) will not apply. 1 socket.
u All calls from the fixed network are forwarded to the phone connected to the Phone u If VoIP is set, then depending on your provider a call-by-call number is preset for

fixed network calls.

u Please check these dialing rules (see page 109) and amend them if you have agreed
special phone tariffs with another provider.
u You should not change the default setting for the connection mode (= "permanent
connection") if you are using VoIP (see page 56). You can only be called via VoIP if this setting is used. Please remember, though, that this setting can result in high connection costs if you have agreed a time-based tariff with your Internet provider. u If there is a power failure, or if you have switched off the Gigaset SX551 WLAN dsl, you can only make calls using a phone connected to the Phone 1 socket. The dialing rules will not apply in this case.

to hide your data and protect it from unauthorised users. For your security, it is only possible to publish data on the Internet via the HTTP service if this is stored in the \gigaset_http directory. FTP FTP (File Transfer Protocol) is a protocol for exchanging files on the Internet. You can use it, for example, to offer files for downloading or to receive files from other users.

Installing a Standard TCP/IP Printer Port Under Windows XP/ 2000
You can use the standard TCP/IP port driver present in this operating system. Make sure that the Gigaset SX551 WLAN dsl is connected and can be reached in the network. A printer need not be connected to the USB port on your Gigaset SX551 WLAN dsl at this point. The following illustrations show installation on Windows XP. Installation on Windows 2000 is essentially the same.
Click Start and in the window that opens click Printer and Faxes.
Double click Add a printer in the window that opens.
The wizard for installing a printer is opened.
In the printer wizard, click Next.
The printer port you are installing will behave like an additional parallel connection to the PC. For this reason, you must click the option button next to Local printer in this window. The check box below should not be ticked in the square Plug & Play printer. If there is a tick present, click the box to remove it.

Click Next.

Click the option button Create a new port. Then select Standard TCP/IP Port from the selection menu in the field next to it. Click Next.
In the wizard for setting up a standard TCPI/IP port, click Next.
In the Printer Name or IP Address input field, enter the IP address of the print server
(Gigaset SX551 WLAN dsl): for example 192.168.2.1. Your input is shown repeated in the second field.
Double click in the Port Name field and enter a name. This name will appear in the
list of printer ports. Call this port, for example, Gigaset_Printerport.
As Windows XP usually first looks for a network card when a printer port is installed, the Additional Port Information Required window is shown.
From the list of standard device types, select the offered type Network Print Server
(1 port) (print server with a printer connection).
The window for finishing the wizard is opened and shows you all the settings you have made.

Click Finish.

Once the wizard for installing the printer port is finished, the Add Printer Wizard is opened.
If you wish to install a printer for this port immediately, click Next and follow the
printer installation wizard's instructions.

If you do not wish to install a printer until later, click Cancel.
Note: The Gigaset SX551 WLAN dsl's printer server does not work bidirectionally. It does not evaluate any of the printer's response messages. For this reason please make sure that your printer is also configured unidirectionally. You can make the relevant printer settings for your printer via Start Settings Printer.
Installing a Printer on the TCP/IP Port Retrospectively
If you connect a printer to this port at a later time, start as described above for installing the printer port.
In this case, however, you should click the selection menu in the Select a Printer

Port window.

Select the connection you have set up from the list: for example
Gigaset_printerport (Standard TCP/IP Port). follow.
Click Next and finish installing the printer driver as instructed in the windows that
Installing a Printer Driver Under Windows 98 SE or ME
The following section describes how to install a printer driver under the Windows 98 SE or ME operating systems as the procedure and windows shown for these operating systems are very similar. The printer driver does not need to be installed on Windows XP and 2000. You have installed your network and it is ready for use.
Insert the CD-ROM included in the scope of delivery into the CD-ROM or DVD drive

of your PC.

Wait until the CD-ROM welcome window appears. Click Gigaset SX551 WLAN dsl. Click Printer port driver for Windows 98 SE or ME.
The welcome window for installing the port driver is opened.
Read the information it contains carefully. Click Next.
The necessary files are copied to your PC and executed. Once all the data has been transferred to your PC, you are prompted to complete the installation of the port driver.
Click Finish. Reboot your PC.
You have now installed the printer port and effectively installed an extra printer interface in your PC. You must carry out this installation on every PC with Windows 98 or ME that is to use this printer in the network. You might possibly still have to correct the IP address for the printer.
Select Start Settings Printers, select the printer and right-click the mouse to

open the pop-up menu.

Select Properties and open the Details tab. Select the port and click Port Settings. Change the IP address if necessary. It must be the same as that for the Gigaset SX551

WLAN dsl.

Instructions for Setting up a Printer on the PC
Once you have installed the printer port you still cannot start printing. The printer port is nothing more than an additional interface on your PC, comparable with the USB port. It means that any printer you install on this port is also regarded as a local printer even though it is located in the network and possibly remote from you. You still need to connect and configure the printer to this port.

of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. We call this license the "Lesser" General Public License because it does Less to protect the users freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. Although the Lesser General Public License is Less protective of the users freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run.
GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to

If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy.

DHCP Dynamic Host Configuration Protocol DHCP handles the automatic assignment of IP addresses to network components. It was developed because in large networks especially the Internet the defining of IP addresses is very complex as participants frequently move, drop out or new ones join. A DHCP Server automatically assigns the connected network components (DHCP Clients) Dynamic IP addresses from a defined IP pool range thus saving a great deal of configuration work. In addition, the address blocks can be used more effectively: since not all participants are on the network at the same time, the same IP address can be assigned to different network components in succession as and when required. The Gigaset SX551 WLAN dsl 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 (for example a LAN) and an insecure network (for example the Internet). A DMZ is useful if you want to offer Server services on the Internet which for security reasons are not to be run from behind the firewall or if Internet applications do not work properly behind a firewall. A DMZ permits unrestricted access from the Internet to only one or a few network components, while the other network components remain secure behind the firewall. DNS Domain Name System The assignment of DNS permits 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. The assignment of domain names to IP addresses on the Internet follows a hierarchical system. A local PC only knows the address of the local Name Server. This in turn knows all the addresses of the PCs in the local network and the superordinated Name Servers, which again know addresses and the next superordinated Name Servers. DNS server See DNS Domain name The Domain name is the reference to one or more Web servers on the Internet. The Domain name is mapped via the DNS service to the corresponding IP address.
DoS attack Denial of Service A DoS attack is a particular form of hacker attack directed at computers and networks with a connection to the Internet. The aim is not so much to steal data but to paralyse the computer or network so severely that the network resources are no longer available. A typical hacker attack involves making a remote computer announce that it is acting for the paralysed computer, for example, and receive the data meant for you. DSL Digital Subscriber Line DSL is a data transmission technique in which a connection to the Internet can be run at 1.5 Mbps over normal telephone lines. A DSL connection is provided by an Internet Provider. It requires a DSL modem. Dynamic IP address A dynamic IP address is assigned to a network component automatically by the DHCP. This means that the IP address of a network component can change with every login or at certain intervals. See also Static IP address DynDNS Dynamic DNS The assignment of Domain names and IP addresses is handled by the Domain Name Service (DNS). For Dynamic IP addresses this service is now enhanced with so-called Dynamic DNS (DynDNS). It enables the use of a network component with a dynamic IP address as a Server on the Internet. DynDNS ensures that a service can always be addressed on the Internet under the same Domain name regardless of the current IP address. Encryption Encryption protects confidential information against unauthorised access. With an encryption system, data packets can be sent securely over a network. The Gigaset SX551 WLAN dsl offers WEP encryption and WPA for secure data transmission over wireless networks. Ethernet Ethernet is a network technology for local networks (LANs) defined by the IEEE as standard IEEE 802.3. Ethernet uses a base band cable with a transmission rate of 10 or 100 Mbps. Exposed Host Exposed Host refers to a PC outside the firewall. See also DMZ

Internet Provider An Internet Service Provider offers access to the Internet for a fee. Internet telephony Voice transmission via the Internet (Voice over IP). IP Internet Protocol The IP Protocol is one of the TCP/IP protocols. It is responsible for addressing parties in a network using IP addresses, and routes data from the sender to the recipient. It decides the paths along which the data packets travel from the sender to the recipient in a complex network (routing).
IP address The IP address is the unique network-wide address of a network component in a network based on the TCP/IP protocol (for example in a local network (LAN) or on the Internet). The IP address has four parts (decimal numbers) separated by full stops (for example 192.168.1.1). The IP address comprises the network number and the computer number. Depending on the Subnet mask, one, two or three parts form the network number, the remainder forms the computer number. You can find out the IP address of your PC using the ipconfig command. IP addresses can be assigned manually (see Static IP address) or automatically (see Dynamic IP address). On the Internet, Domain names are normally used instead of the IP addresses. DNS is used to assign domain names to IP addresses. The Gigaset SX551 WLAN dsl has a Private IP address and a Public IP address. IP pool range The Gigaset SX551 WLAN dsl's IP address pool defines a range of IP addresses that the router's DHCP Server can use to assign Dynamic IP addresses. ISP (Internet Service Provider) Internet Provider LAN Local network A local network links network components so that they can exchange data and share resources. The physical range is restricted to a particular area (a site). As a rule, the users and operators are identical. A local network can be connected to other local networks or to a wide-area network (WAN) such as the Internet. With the Gigaset SX551 WLAN dsl, you can set up a wired local Ethernet network and a wireless IEEE 802.11g standard network (WLAN). Lease time The lease time defines the period of time for which the PCs keep the Dynamic IP address assigned to them by the DHCP server without changing them. Local IP address See Private IP address MAC address Media Access Control The MAC address is used for the globally unique identification of a Network adapter. It comprises six parts (hexadecimal numbers), for example 00-90-96-34-00-1A. The MAC address is assigned by the network adapter manufacturer and cannot be changed.

Mbps Million bits per second Specification of the transmission speed in a network. MER MAC Encapsulated Routing MRU Maximum Receive Unit The MRU defines the maximum user data volume within a data packet. MTU Maximum Transmission Unit The MTU defines the maximum length of a data packet that can carried over the network at a time. NAT Network Address Translation NAT is a method for converting IP addresses (mostly Private IP addresses) within a network into one or several Public IP addresses on the Internet. With NAT, several network components in a LAN can share the router's public IP address to connect to the Internet. The network components of the local network are hidden behind the router's IP address registered on the Internet. Because of this security function, NAT is frequently used as part of the Firewall of a network. If you want to make services on a PC in the local network available on the Internet despite NAT, you can configure the Gigaset SX551 WLAN dsl as a Virtual server. Network A network is a group of devices connected in wired or wireless mode so that they can share resources such as data and peripherals. A general distinction is made between local area networks (LANs) and wide area networks (WANs). Network adapter The network adapter is the hardware device that creates the connection between a network component and a local network. The connection can be wired or wireless. An Ethernet network card is an example of a wired network adapter. The Gigaset PC Card and the Gigaset USB Adapter are examples of wireless network adapters. A network adapter has a unique address, the MAC address.
Port Data is exchanged between two applications in a network across a port.The port number addresses an application within a network component. The combination of IP address/port number uniquely identifies the recipient or sender of a data packet within a network. Some applications (for example 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 Gigaset SX551 WLAN dsl directs data packets from the Internet that are addressed to a particular Port to the corresponding port of the appropriate network component. This enables servers within the local area network to offer services on the Internet without them needing a Public IP address. See also: Virtual server PPPoA Point-to-Point Protocol over ATM PPPoA is a Protocol for connecting network components in a local Ethernet network to the Internet via an ATM network. PPPoE Point-to-Point Protocol over Ethernet PPPoE is a Protocol for connecting network components in a local Ethernet network to the Internet via a modem. Private IP address The private IP address (also known as the local IP address) is a network component's address within the local area network (LAN). The network operator can assign any address he or she wants. Devices that act as a link from a local network, such as the Gigaset SX551 WLAN dsl, 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 about data formats, time frames and handling possible errors. Communications between two applications require different protocols at various levels, for example the TCP/IP protocols for the Internet. Public IP address The public IP address (also known as the global IP address) is a network component's address on the Internet. It is assigned by the Internet Provider. Devices that create a link from a LAN to the Internet, such as the Gigaset SX551 WLAN dsl, have a public and a Private IP address. Radio network See WLAN
