Introduction 1 Introduction Network links in conferences or presentations, access to resources in adjacent buildings and exchanging data with mobile units are only a few of the options available with a wireless LAN. The access point plays the central role in enabling these options in an existing wired network. All stations in the wireless network access the LAN via the access point. Your entire LAN is connected to the outside world via the integrated IP router and the ISDN interface.
2 Introduction The maximum area in which wireless network adapters in mobile stations and the access point can reach each other and exchange data is known as a radio cell. English Radio cell All of the standard functions of a wired network are also available in a wireless network: Access to files, servers, printers etc. is possible as is the integration of the mobile stations into an internal company e-mail system.
Introduction All computers with wireless network cards are able to access a wired network via an access point. The access point acts as the connection between the LAN and the WLAN and it also forms the switching center for data traffic within the WLANs. Infrastructure network Peer-to-LAN A wireless network with an access point is generally called a peer-to-LAN network. In the language of wireless networking, it is known as an infrastructure network.
4 Introduction English point, add a second access point. The access points can then be connected using simple network cables and a hub, for example. Radio cells can also overlap to ensure good coverage. Different channels (up to 14 channels are available) can be selected to prevent interference between the cells. Roaming Roaming is the transparent switching between nieghbouring radio cells. The user can move from one cell to the other without losing the network connection.
Introduction 5 English This enables additional applications such as access to the Internet for all computers in the LAN and WLAN together with all the functions of an IP router.
6 Introduction What does the ELSA LANCOM Wireless IL-2 offer? The following is an outline of the principal features of the device giving you a quick overview of its capabilities. English Easy installation 쮿 쮿 쮿 쮿 쮿 Connect the ELSA LANCOM to the power supply. Establish a link to the LAN. Plug in the ISDN cable. Switch it on. Go! LAN connection Access points for wireless networks by ELSA function in Ethernet environments.
Introduction 7 The ELSA LANCOM Wireless is connected to the S0 interface(s) of an ISDN Basic Rate Interface in point-to-multipoint configuration (multi-device terminal) or in point-to-point configuration (system terminal). The router automatically detects your connection type and the D-channel protocol being used. Dial-up connections using DSS1 or 1TR6 can also be used, as can leased-line connections. Leased-line connections are an optional feature that can be requested from ELSA.
8 Introduction If charge information is not available from your ISDN connection, you can also limit the active connect time for a specified period. The router will not permit the establishment of connections once this time has elapsed. English Least-cost routing Even if there is a large selection of telecommunications service providers you can always use the cheapest lines using the least-cost router.
Introduction 9 ISDN Basic Rate Interface. Now you can access the router using a PPP connection and configure it from your location. The first time the device is configured, access to it is secured by a password and thereafter it remains inaccessible to unauthorized callers. Your device has a flash ROM memory to ensure that its software remains state of the art. This allows new firmware to be loaded onto the device without the need to open it up.
10 Introduction NetBIOS proxy English Routers from ELSA offer a special feature for linking Microsoft peer-to-peer networks: With the integrated routing of IP NetBIOS packets, the linking of Windows networks becomes child's play. The remote stations relevant for the exchange of data are entered in a list to ensure that not every NetBIOS packet results in the establishment of a connection.
Installation 11 Installation Package contents Please ensure that the delivery is complete before beginning with the installation. The package should include the following components: 쮿 쮿 쮿 쮿 쮿 쮿 쮿 Access point ELSA LANCOM Wireless IL-2 Power supply unit ELSA AirLancer MC-2 wireless network adapter LAN connector cable ISDN connector cable Documentation CD containing ELSA LANconfig and other software and electronic documentation If anything should be missing, please contact your dealer.
12 LEDs Installation You will find a number of LEDs as display elements on the front panel. English 쐃 쐇 쐋 쐎 쐏 쐄 쐂쐆 쐊 The red LED of the wireless network adapter indicates that a connection has been established between the card and access point. The yellow LED of the wireless network adapter indicates the number of mobile stations logged onto the access point. For example, when three stations are logged on, the LED flashes three times in quick succession before pausing briefly.
Installation 13 The 'WAN Channel-1' LED on the access point shows the activity on the first B channel on the ISDN port. The Reset button is recessed in the case and can only be reached with a pointed object such as a paper clip. Press the Reset button until all of the LEDs light up to reset the unit to its factory defaults. Now turn the whole thing around and take a look at the bottom.
14 Installation and access point. The flickering of the green LED on the wireless network adapter indicates that it is searching for other stations in the WLAN. The 'LAN Status' LED signals the correct connection between the access point and the LAN. English Software installation The access point can be quickly and easily set up for the required application using the ELSA LANconfig configuration software for Windows operating systems.
Installation 15 English 햲 Start the new software with Start 왘 Programs 왘 ELSAlan 왘 ELSA LANconfig. 햳 Select the option 'Make all settings automatically' if you are not familiar with networks and IP addresses, and one of the following conditions is applicable: – You have not yet used IP addresses in your network but would like to do so starting now. You are not concerned about the specific IP addresses that will be used.
16 Installation English – You have previously used IP addresses for the computers in your LAN. Assign a free address from the previously used address range to the access point and specify whether the access point should act as a DHCP server. Further information on the structure of networks in general and IP addressing can be found in the electronic documentation on the ELSA LANCOM Wireless CD. The functions of the DHCP server are described later in this manual.
Configuration modes 17 Configuration modes It will nevertheless be necessary for you to add some information and configure the router to your specific needs. These settings are made as part of the configuration process. This section will show you the programs and routes you can use to access the device and set it up. And, if the team at ELSA has produced new firmware with new features for your use, we will show you how to load the new software.
18 Configuration modes server you can have the IP addresses for all computers on the network assigned automatically (see also chapter 'Automatic Address Administration with DHCP'). English Beginning configuration using ELSA LANconfig Start the configuration tool ELSA LANconfig e.g. via the Windows taskbar with Start 왘 Programs 왘 ELSAlan 왘 ELSA LANconfig. ELSA LANconfig searches the local area network for devices.
Configuration modes 19 Start up configuration using Telnet Start configuration using Telnet with the command from a DOS box: telnet 10.1.80.125 After the entry of the password (if you specified one to protect the settings) all commands from the 'Configuration Commands' section are available. Configuration commands Commands and path specifications are entered using the normal DOS or UNIX conventions if you are using Telnet or a terminal program to configure the device.
English 20 Configuration modes This command... ... means this... ... for instance: repeat repeats the action at an interval of the number of seconds specified. Any key can be used to terminate the repetition. repeat 3 dir/status/wan-statistics displays the current WAN statistics every 3 seconds time sets the system time and date time 24.12.1998 18:00:00 language sets the language for the current configuration session.
Configuration modes – If the device no longer responds and it is therefore impossible to log in, it automatically loads the previous firmware version and reboots the device with it. 'Manual': With the third option you can define a time period during which you want to test the new firmware yourself. The device will start with the new firmware and wait for the preset period until the loaded firmware is manually activated and therefore becomes permanently effective.
22 Configuration modes English This command sends the corresponding file to the given IP address using the writeflash parameter. Binary file transfer must be set for TFTP. However, many systems have the ASCII format preset. This example for Windows NT shows you how to achieve this by using the '-i' parameter. The device is booted up following a successful firmware upload and this activates the new firmware switch directly.
Operating modes and functions 23 Operating modes and functions This section is an introduction to the functions and operating modes of your device.
24 Operating modes and functions English 햳 In the list of found devices, click on the access point that you would like to configure. In the 'Management' configuration group select the 'Interfaces' tab. 햴 Set the new value for the WLAN domain. The WLAN domain must be identical for all participants in a wireless network.
Operating modes and functions 25 Security for your configuration A number of important parameters for the exchange of data are established in the configuration of the device. These include the security of your network, monitoring of costs and the authorizations for the individual network users. Needless to say, the parameters that you have set should not be modified by unauthorized persons. The ELSA LANCOM Wireless thus offers a variety of options to protect the configuration.
26 Operating modes and functions 쮿 쮿 'Lock configuration after' (Login-errors) 'Lock configuration for' (Lock-minutes) English Access control via TCP/IP Access to the internal functions of the devices through TCP/IP can be restricted using a special filter list. Internal functions in this case means Telnet or TFTP sessions to configure the ELSA LANconfig.
Operating modes and functions 27 No password? The PPP does indeed offer this special option: It is possible to request a form of protection available specifically to this protocol, that is to say PAP (Password Authentication Protocol) or CHAP (Challenge Handshake Authentication Protocol). This is a form of protection which your device demands from the remote station.
28 Operating modes and functions the router, if the caller is not identified by means of CLI. On the other hand, the caller incurs no costs if identification of the caller's number is possible and is accepted. If the router is requested to call back, the Fast Callback procedure (patent pending) can be used with many other parties. This speeds up the callback procedure considerably.
Operating modes and functions 29 Settings in the charge module The current charge and connect-time information is retained when rebooting (e.g. when installing new firmware) is not lost until the unit is switched off. All of the time values indicated here are in minutes. ISDN connections Data communications between two ISDN terminal devices takes place via ISDN connections. These connections can be realized either as dial-up or leased-line connections.
30 Operating modes and functions English 쮿 쮿 쮿 Timeouts These times indicate the length of time the B channels should remain active after – the last data has been exchanged across static connections for the holding time B1. – the data throughput has dropped below a specified level for the holding time B2 in dynamic connections. WAN-layer The layer stands for a collection of protocols to be used for this connection. The layer must be set up identically on both sides of the connection.
Operating modes and functions 31 Router interface settings The router interface settings determine the parameters to be used for each interface (i.e. each S0 port) while in router mode. These parameters do not apply to the other operating modes of the units. Specifically, they are: 쮿 Subscriber numbers (MSN/terminal device selection numbers) The router responds to incoming calls for these numbers. Multiple numbers are separated by semicolons.
32 Operating modes and functions English Normally the number specified in the CAPI application is transferred to the remote station via the LANCAPI during active call establishment. No number is transferred by the LANCAPI if this number has not been specified or the number is invalid. This option lets you transfer the first number entered in the 'Subscriber Number' field if no number has been specified in the CAPI application.
Operating modes and functions 33 Round-robin list If a remote station can be reached using several numbers, enter the first number in the name list and the rest in the round-robin list. 쮿 Remote site Name of the remote station as specified before in the name list. 쮿 RoundRobin Additional numbers for this remote station. Multiple numbers are separated by hyphens.
34 Operating modes and functions Script English The script list in the ELSA LANconfig can be found in the 'Communication' configuration section on the 'Protocols' tab, or under /Setup/WAN-module/Script List during telnet or terminal sessions. If the processing of a script is required to connect to a remote station, enter the script here and assign it to a remote station. The layer-3 protocol selected in the layer list for this connection must support scripting.
Operating modes and functions 35 Dialup-remote Subscriber number transmitted by the remote station (incl. country and long distance codes if available). 쮿 Remote site Name of the remote station as specified in the name list. The remote station will be called back if so specified in the name list. English 쮿 Point-to-point protocol ELSA routers also support the Point-to-Point Protocol (PPP).
36 Operating modes and functions The phases of PPP negotiation Establishment of a connection using PPP always begins with a negotiation of the parameters to be used for the connection. This negotiation is carried out in four phases which should be understood for the sake of configuration and troubleshooting. English 쮿 Establish phase Once a connection has been made at the data communication level, negotiation of the connection parameters begins through the LCP.
Operating modes and functions 37 In this column of the PPP list... ...enter the following values: Device-name Name the remote station uses to identify itself to your router Auth. Security method used on the PPP connection ('PAP', 'CHAP' or 'none'). Your own router demands that the remote station observes this procedure. Not the other way round. This means that 'PAP' or 'CHAP' security is not useful when connecting to Internet service providers, who may not wish to provide a password.
38 Operating modes and functions reliable and stable if a valid response to this request for information is returned (LCP echo reply). This request is repeated at defined intervals so that the connection can be continually monitored. English What happens when there is no reply? First a few retries will be initiated to exclude the possibility of any short-term line interference. The line will be dropped and an alternative route sought if all the retries remain unanswered.
Operating modes and functions 39 The route with the IP address “255.255.255.255” with network mask “0.0.0.0” is the default route. All data packets that cannot be routed by other routing entries are sent over this route. Router Name The router name indicates what should happen with the data packets that match the IP address and network mask. Routes with the router name “0.0.0.0” identify exclusion routes. Data packets for this “zero route” are rejected and are not routed any further.
40 Operating modes and functions The router can check the source and destination ports of data packets using the TCP or UDP protocols. It can then deduce the purpose of the data from these ports. For example, FTP accesses or Telnet sessions can be identified. English Proxy-ARP A special feature of the IP router is the proxy ARP. This proxy is used if the transmission of data to IP addresses takes place in the same logical network as the sender, but the destination address is still reached via a router.
Operating modes and functions 41 How can you assist the workstation computer now? Certain computers, however, do not know how to handle ICMP redirects. To ensure that the data packets reach their destination anyway, use local routing (in ELSA LANconfig in the 'TCP/IP' configuration section on the 'Router' tab or in the /Setup/IP Routermodule/Local Routing On menu). In this way you instruct the router itself in your device to send the data packet to other routers.
42 Operating modes and functions English What do the entries mean? IP address and network mask identify the destination network, the distance shows the number of routers between the transmitter and receiver, the last column shows which router has revealed this route. This leaves the 'Time'. The dynamic table thus shows how old the relevant route is. The value in this column acts as a multiplier for the intervals at which the RIP packets arrive. A '1', therefore, stands for 30 seconds, a '5' for about 2.
Operating modes and functions 43 Two addresses for the router 쮿 'Off': No masquerading. Masquerading makes use of a characteristic of TCP/IP data transmission, which is to use port numbers for destination and source as well as the source and destination addresses. When the router receives a data packet for transfer it now notes the IP address and the sender's port in an internal table. It also enters this new port on the table and forwards the packet with the new information.
44 Operating modes and functions DNS forwarding English Names rather than IP addresses are generally used to access a server over the Internet. Who knows which address is behind 'www.domain.com'? The DNS server, of course. DNS stands for Domain Name Service and refers to the assignment of domain names (such as domain.com) to the corresponding IP addresses. This information must be constantly updated and be accessible all over the world at any time.
Operating modes and functions 45 They also need the addresses of DNS-server and NBNS-server as well as that of a default gateway through which the data packets are to be routed from addresses that are not available locally. In such situations, the DHCP (Dynamic Host Configuration Protocol) is the ideal solution. Using this protocol, a DHCP server in a TCP/IP-based LAN can dynamically assign the necessary addresses to the individual stations.
46 Operating modes and functions English 쮿 쮿 'off': The DHCP server is permanently disabled. 'auto': The server is in automode. In this mode, after switching it on, the device looks for other DHCP server within the local network. – The device then disables its own DHCP server if any other DHCP servers are found. This prevents the unconfigured device from assigning addresses not in the local network when switched on. – The device then enables its own DHCP server if no other DHCP servers are found.
Operating modes and functions 47 subnetworks for some of the workstation computers), it may be necessary to use a different broadcast address. In this case, the broadcast address to be used is entered in the DHCP module. DNS and NBNS assignment This assignment is based on the associated entries in the 'TCP-IP module'. If no server is specified in the relevant fields, the router passes its own IP address as a DNS address. This address is determined as described under 'IP address assignment'.
48 Operating modes and functions Priority for the DHCP server – Request assignment English In the default configuration, almost all the settings in the Windows network environment are selected in such a way that the necessary parameters are requested via DHCP. Check the settings by clicking Start 왘 Settings 왘 Control Panel 왘 Network. Select the 'TCP/IP' entry for your network adapter and open Properties. Check the various tabs for special entries, such as for the IP address or the standard gateway.
Operating modes and functions 49 Configuring the DHCP server 쮿 쮿 You have not yet configured a network or your existing local network does not use TCP/IP. The DHCP server in your new ELSA lets you assign IP addresses to all of the computers in the network and to the router in a single operation. You are already using TCP/IP but without a DHCP server, and you would now like to convert to DHCP operation.
50 Operating modes and functions English change will require a reboot, after which the computer will automatically request an IP address from the DHCP server's address pool. 햵 Install the configuration tool ELSA LANconfig on a computer in the network. 햶 Start the program from the 'ELSAlan' program group. When loading, the ELSA LANconfig, will detect an unconfigured router in the network and will launch the wizard for the basic settings.
Operating modes and functions 51 – After a few seconds, all of the computers in the network will be checked and are assigned a new IP address by the DHCP server as required. The computers also receive additional parameters such as the broadcast address, DNS server, default gateway, etc.
52 Operating modes and functions 쮿 The DNS server in the ELSA LANCOM Wireless can also be used as an extremely convenient filter mechanism. Requests for domains can be prohibited throughout the LAN, for subnetworks, or even for individual computers – simply by specifying the domain name.
53 English Operating modes and functions 햵 The main task of the DNS server is to distinguish requests for names in the Internet from those for other remote stations. Therefore, enter all computers into the DNS table – for which you know the name and IP address, – that are not located in your own LAN, – that are not on the Internet and – that are accessible via the router. For example, if would like to access the mail server at your headquarters (name: mail.yourdomain.com, IP: 10.0.0.
54 Operating modes and functions English 햶 Finally, use the filter list to specify the users that cannot access certain names or domains. cd setup/dns-module/filter-list set 001 www.offlimits-domain.com 0.0.0.0 0.0.0.0 This entry (with the index '001') prohibits this domain for all of the computers in the local network. The index '001' was selected freely and is only intended to enhance the overview.
Operating modes and functions 55 The names publicized in this manner should, of course, be collected and made available at a central location in the Microsoft Network. If two Microsoft Networks are to be connected using a router, then such a name collection point, a so-called NetBIOS nameserver (NBNS), must be present on both sides. 쮿 쮿 A WINS server (Windows Internet Name Service server) can be installed in the network for this purpose.
56 Operating modes and functions English 쮿 In its proxy function, the unit answers queries to computers already known in the NetBIOS module (on the billboard) by proxy for those computers. After the initial exchange of information, no new connections are established as a result of queries to workstations in the local network, or to known workstations in the remote network.
Operating modes and functions 쮿 57 Service File and printer sharing permits drives and printers to be shared with other users in the Windows Network. Windows Network settings 쮿 Name and group designation Click Start 왘 Settings 왘 Control Panel 왘 Network and switch to the Identification tab. The name of the workstation must be unique. That applies to all Windows Networks, and all groups that you intend to connect using NetBIOS within these networks. Names also may not recur in different groups.
58 Operating modes and functions All users intending to access shared resources must log on with their names and passwords when booting Windows. English In the Windows Explorer, right-click the drives, folders or printers that you would like to share with others on the network and select the item Sharing from the context menu. Enter a name for the shared resource and a description if required.
Operating modes and functions 59 English connection on the DEFAULT route. This has been preset in the unit's factory defaults. 햴 Next, enter the remote station for routing via NetBIOS. Change over to the ELSA LANconfig 'NetBIOS' configuration section and create a new entry in the 'NetBIOS via IP Routing' table. Alternatively, enter the following when configuring via telnet: cd /Setup/NetBIOS-module/Remote-table set nhamel.
60 Operating modes and functions this initial connection. Computers on the remote side cannot be accessed until this operation is complete. Dial-up procedure for a remote access station English Accessing a Windows Network with a single computer via remote access can also be taken care of quickly. 햲 The ELSA LANCOM Wireless and the remote access computer must be prepared for network access as described in the Workshop.

62 Operating modes and functions English Office communications and ELSA LANCAPI LANCAPI from ELSA is a special version of the popular CAPI interface. CAPI (Common ISDN Application Programming Interface) establishes the connection between ISDN adapters and communications programs. For their part, these programs provide the computers with office communications functions such as a fax machine or answering machine.
Operating modes and functions 63 햳 Select the 'Install LANCOM software' entry. If necessary, the system is restarted and LANCAPI is then ready to accept all jobs from the office communications software. After successful installation, an icon for LANCAPI will be available in the Start Menu. A double-click on this icon opens a status window that permits current information on the LANCAPI to be displayed at any time.
64 Operating modes and functions English – It is also possible to set the interval at which the client checks whether the found or listed servers are still active.
65 English Operating modes and functions 햳 Activate the LANCAPI server, or set it to permit outgoing calls only. In the latter case, the LANCAPI will not respond to incoming calls – to receive faxes, for example. Permitting outgoing calls only is useful if you do not have a specific call number available for the LANCAPI. 햴 When the LANCAPI server is activated, enter the call numbers to which the LANCAPI should respond in the 'Number' field. You can enter several call numbers separated by semicolons.
66 Operating modes and functions English or outgoing) when both B channels are already busy (priority control). The available options are: 쮿 쮿 쮿 The connection cannot be established via the LANCAPI. A fax program using the LANCAPI will then probably attempt to send again at a later time. The connection via the LANCAPI can then be established when a main channel is free. A main channel is the first B channel used when a router connection is established. Secondary channels are used for channel bundling.
Operating modes and functions 67 Unfortunately, the most inexpensive rates vary from provider to provider depending on the time of day and region. In the morning Provider 1, Provider 2 in the afternoon and possibly Provider 3 for international calls. To always have the most economical connection for telephone calls, surfing the Internet or transferring data to other networks, it would be necessary to decide which provider is the least expensive before each connection.
68 Operating modes and functions These four entries mean that all connections to Bristol (or other numbers with the prefix '0117') on weekends will be made using the provider with the network prefix '4'. Between 8:00 AM and 6:00 PM on weekdays, these calls will be made using the provider with the network prefix '0800'. International calls on Sundays will be made using the provider with the network prefix '4'.
Operating modes and functions 69 Setting up the least-cost router Two essential questions must be clarified with regard to configuring the least-cost router: 쮿 Which operating modes of the ELSA LANCOM Wireless should the services of the least-cost router use? Which calls should be routed over which provider? To answer these questions, proceed as follows: 햲 In ELSA LANconfig, go to the 'Least Cost Router' configuration section on the 'General' tab. 햳 Enable the least-cost router function.

Technical basics R1 Technical basics Wireless network according to the IEEE-802.11 standard The ELSA LANCOM Wireless series devices conform to the IEEE-802.11 standard. This standard is a supplement to the current IEEE standards for LANs, with IEEE 802.3 for Ethernet being the most well-known. In fact, wireless networks that comply with 802.11 can easily be connected to existing Ethernet networks. This is the most important function of the ELSA LANCOM Wireless units.
English R2 Technical basics has a specific parameter – the name of a WLAN domain. From the viewpoint of the user, the WLAN domain is a freely chosen string of up to characters; at the radio level, this name is converted to an additional addressing component that permits data packets to be associated with a specific cell. To enter an existing wireless LAN, the name of the WLAN domain must be entered in the advanced settings for the network adapter driver.
Technical basics R3 and thus knows exactly how any given data packet is to be handled. This process is also known as bridging. As mentioned earlier, an Ethernet backbone can also be used to extend the range of a wireless LAN. In this case, multiple access points can be incorporated in the same LAN and configured to the same WLAN domain. When a mobile station wants to establish a connection with the network, it seeks out and logs onto the access point with the strongest signal.
R4 Technical basics Network technology English This paragraph will give you a brief introduction to the basics of network technology. These descriptions do not cover all possible techniques, processes and terms associated with network technology. They only covered to the degree necessary to provide an understanding of the product information.
Technical basics Host R5 Host Data packet Access to the Internet is also established through point-to-point connections. Even though the data packets are sent from the host at the Internet user to the host at the Internet provider (server) via several routers, every data packet still has its own specific destination. Furthermore, the routers will only forward the data packets to one recipient. That's why we also call this connection unambiguous.
R6 Technical basics Host Data packet with recipient information English Host: Sender Host Host: Recipient Kinds of networks Protocol An important prerequisite for communications between computers is a common language among the hosts. In the world of network technology this language is called “network protocol” or simply “protocol”. TCP/IP The most broadly distributed network protocol is the TCP/IP (Transmission Control Protocol/Internet Protocol).
Technical basics R7 IP address IP addresses are used in IP networks for communications between various devices. In this case, every host has its own unique address by which it can be identified unambiguously. What does an IP address look like? It comprises four bytes separated by points, making a total of 32 bits. Each of the four bytes can take on values from 0 to 255, e.g. 192.168.130.124. To be precise, the IP address refers to the interface, and not the host itself.
R8 Technical basics English And you can also see that there are more bits available to identify the individual hosts in a connected network if there are fewer bits in a netmask that contain a one. While only 254 different addresses could be allocated in the first example with the netmask 255.255.255.
Technical basics R9 There are two considerations when using these IP addresses: 쮿 The IP addresses used in a private network should not leave this network, i.e. an Internet connection is only possible when using IP masquerading, for example. The packets for these IP addresses will not be routed in the Internet, i.e. backbone routers will simply reject such IP packets. Depending on the provider, consequences may result if such IP packets are released on the Internet.
R10 Technical basics Host 'Smith' External host Marketing Example Inc.'s router English Superordinate network: Example Inc. Development External router as a connection to other networks As an example, think of a company with one large network, in which the different divisions are incorporated as small subnets. The address of the network for the marketing division is made up hierarchically from the address of the company and that of the department.
Technical basics R11 Now imagine a router that is connected to the network of Example Inc. through an interface. If it receives a packet with destination address '192.168.100.4' and netmask '255.255.255.0', it will compare this with every network address it knows. In doing so it carries out a logical AND with the netmask, and compares the results with the network address: '192.168.100.4' AND '255.255.255.0' is '192.168.100.0'. This is the network address of the Example Inc. network.
R12 Technical basics via the MAC protocol, they are called MAC addresses. They can be thought of as the fingerprint of the interface hardware. MAC addresses can look like this, for example: 0080-C7-6D-A4-6E. English MAC addresses are independent of IP addresses. An IP host whose interface works through a LAN has an IP and a MAC address.
Technical basics IP host in the LAN R13 IP host in the LAN The router in the LAN: knows only the address of the LAN In contrast, the host is confronted with a more difficult task than the router. In case of a wired point-to-point interface, the host knows that all packets that it sends through the interface automatically arrive at its router, for example. In case of the point-to-multipoint connection to the LAN, it has to distinguish two cases, however.
R14 Technical basics sends an ARP request packet to all hosts in the LAN (with the LAN broadcast address as a target address). Host 'Smith' English ARP request to '137.226.4.20' Host 'Miller' This ARP request packet is simply a question to all hosts listening to the IP address '137.226.4.20'.
Technical basics R15 EB'” in the ARP table and tells his LAN interface: “Send this IP packet to the computer with the MAC address '00-10-5A-31-20-EB'”. Imagine the second task, sending an IP packet from host 'Smith' to the remote host 'External' with IP address 151.189.12.43. Host 'Smith' compares the IP address with his network address and realizes that host 'External' is located outside the LAN. So host 'External' can only be reached through the router.

R48 Description of the menu options Setup English This menu allows you to query and modify all the system parameters that are necessary to the functioning of the devices.
Description of the menu options R49 Since the router permits only upper case letters in the device name list, the name is transferred in uppercase letters in the case of a verification by the ELSA protocol. Special characters should not be used in device names unless the remote station can process them. English In addition, the device names you assign must be unique. For example, you might match the device names to the location (e.g. Aachen, Berlin, Provider, etc.).
R50 Description of the menu options English Below is a detailed description of the meaning of each field: Routerinterface-list Ifc Designates the associated interface. Protocol D channel protocol setting.

B channel settings for a leased-line connection.
Description of the menu options The names entered in the name list are needed by the router to determine the correct remote station and corresponding layer name. The name list is also used for the callback function.
R52 Description of the menu options English 쮿 쮿 Callback options Off No callback is made. Looser The router stops attempting to establish a connection when there is a call from this remote station (reciprocal call establishment). This setting must be used when a callback from the remote station is expected. Auto (not applicable to Windows 9x or Windows NT) The connection will be rejected and a direct callback will be initiated if the remote station is specified in the number list.
Description of the menu options R53 Layer-list Device-name In the device name column, you can enter a remote device name from the name list. If one line in the Round Robin list is insufficient for all desired call numbers, the line can be extended as shown below: The # character and a unique index are added to the device name (e.g. AACHEN#1) and it is entered on the next line. Round-Robin The DDI numbers of all possible remote stations are entered here under their corresponding device names.
R54 Description of the menu options In the lay-3 column, you can define additional headers for data transmission in ISDN. You can select from among the following settings: TRANS No additional header is inserted (higher data throughput). Always select this setting if the remote station sends the data transparently via ISDN layer 3 (e.g. transparent HDLC, transparent X.75LAPB). ELSA The data is provided with an ELSA header.
Description of the menu options The lay-1 column allows you to define the speed at which the data is sent in ISDN. HDLC64K The data is transmitted at 64,000 bps. HDLC56K The data is transmitted at 56,000 bps. This setting is especially important for connections in the USA. In order for the device to function correctly as a bridge, ETHER must always be entered in the Encaps field. If the ELSA LANCOM is used as a router, any entry may be made and it should be adapted to the remote station.
R56 Description of the menu options Time In this column, you can enter the period of time between two remote station verifications specified in minutes. The CHAP protocol must be set here. Default: 0 Try In this column, you can specify the number of times the verification attempt is to be repeated. If verification fails, the connection is immediately terminated. Default: 5 English Conf, Fail and These parameters may be used to influence the operation of the PPP.
Description of the menu options Script-list R57 Some Internet providers (e.g. CompuServe) conduct a script-controlled log-on procedure before a PPP negotiation. In order to be able to establish this type of connection as well, a simple script processing procedure is also implemented in the ELSA LANCOM (see 'Script processing').
R58 Description of the menu options English Disconnect This command allows you to release an existing connection. If a connection is released manually, the name of a remote station may also be entered in the remote configuration. In this case, only the connection to the remote station specified is released. If a connection to the remote station specified does not exist, there is no further response. However, if a remote station name is not entered, all existing connections will be released.
Description of the menu options R59 as a 12-digit hexadecimal value, with the first six digits '00a057' standing for an ELSA device. The spare heap blocks for the local network affect the number of buffers that are always available for receiving frames from the local network. The default value is 10, which ensures that, e.g., four Telnet sessions can be activated via the local network at any time. Setup/TCP-IP-module This menu allows you to enter settings for the TCP/IP module.
R60 Description of the menu options If the IP address is assigned to the router by the Internet provider by PPP, all computers in the network linked by IP address and IP network mask are normally routed. These computers can then also be accessed directly from the Internet. IP network mask The network mask belonging to the IP address must be entered here. The default setting English is 255.255.255.0 (class C network). A network mask of 255.255.255.
Description of the menu options R61 For reasons of consistency, the access control is based on all “internal functions” of the router.
English R62 Description of the menu options NBNS-default The entry NBNS-default (NetBIOS Name Server) is required to announce the NBNS responsible for their own network for computers that have direct access via PPP to the router. NBNS With the entry NBNS-Backup a second name server can be named, which is used if the NBNS fails. Table-ARP This option allows you to display the ARP table (ARP cache), which is managed automatically for the purpose of mapping IP addresses onto physical terminal addresses.
Operating /IP-router-module IP router module settings Loc.-routing Activates/deactivates local routing Routing-method Routing method for IP packets RIP-config Settings for IP-RIP operation Masquerading Settings for IP masquerading R63 This option allows you to activate or deactivate the IP router module. In the default configuration, the IP router module is activated. Activating the IP router module also activates the TCP/IP module.
R64 Description of the menu options English Address ranges that are prohibited in the Internet are excluded from transmission by preset entries in the IP routing table (the router name 0.0.0.0 means that packets to these addresses are not transmitted). The IP routing table below is provided by way of example and also shows the default settings: IP-address IP netmask Router-name Distance Masquerade 192.168.0.0 255.255.0.0 0.0.0.0 0 Off 172.16.0.0 255.240.0.0 0.0.0.0 0 Off 10.0.0.0 255.0.0.
Description of the menu options R65 The last line is an entry for the “default route”. The IP address 255.255.255.255 means the same as 0.0.0.0 (for technical reasons, 0.0.0.0 cannot be entered in the first column). Because it contains the IP network mask 0.0.0.0, this line is always appropriate after the rest of the table has been searched.
R66 Description of the menu options The setting all filters out every packet from the specified source network or to the destination network. 쮿 Type Filter type. The possible values are Always-filt., Connect-filt. and Internet-filt. English – Always filter: The packet is discarded. – Connect filter: The packet is discarded if there is no connection to the remote station. – Internet filter: The packet is discarded if its destination can be accessed only via the default route.
R67 Proxy-ARP This option allows you to activate or deactivate the proxy ARP mechanism (default: 'Off'). This function permits data to be transmitted to IP addresses within the same logical network as the sender, e.g. when linking individual workstation computers (teleworkers) to the corporate network via TCP-IP Loc.-routing Local routing enables the router to forward data packets via the local network.
R68 Description of the menu options Setup/IP-router-module/RIP-configuration English This option allows you to enter settings for the management of IP-RIP packets. The menu has the following layout: RIP-type /RIP-configuration Settings for IP-RIP operation Type RIP compatibility switch R1-mask Management of network masks Table-RIP Dynamic IP routing table This option allows you to select the method to be used for handling the IP-RIP packets.
Description of the menu options R69 Here specify whether RIP packets will be sent to the LAN or the cable network.
R70 Description of the menu options network that the router is currently masking. The dynamic masquerading table can contain up to 2048 entries and has the following layout: Intranet addr. S-port Protocol Time 10.1.1.10 1234 TCP 10 English The different columns have the following meaning: 쮿 쮿 쮿 쮿 Intranet-addr.
Description of the menu options R71 In principle, any SNMP manager can use this command to obtain information from the router. The syntax is used to direct the router to enter the given address in the monitor table and to send traps to it. If the traps are not received within the set hold time, the address will be automatically deleted from the table. A hold time of '0' permanently retains the entry in the table. Delete-monitor This command removes the entries from the monitor table.
R72 Description of the menu options English If there is no IP or Intranet address entered in the TCP/IP module (e.g. delivery status), the router will issue IP addresses from the address range 10.0.0.2 – 10.0.0.253 to all DHCP clients in auto mode. Start-addresspool End-addresspool The IP address assigned is taken from the address pool selected ('Start-address-pool' to 'End-address-pool'). Any valid addresses in the local network can be entered here. If 0.0.0.
Description of the menu options In the DCHP module, the 'Table-DCHP' option allows you to verify (or look up) the assignment of IP addresses to the relevant computers. This table has the following layout: IP-address MAC-address Timeout Hostname Type 10.1.1.
R74 Description of the menu options Watchdogs Sets handling of watchdog packets. Compensation Compensation type of routing information. WAN-update-min. Compensation interval in minutes. The Scope-ID menu item can be used to specify the NetBIOS scope in which the device is located. It then sees only those NetBIOS packets originating in the same NetBIOS scope; all other packets are automatically rejected. The scope ID is only used in conjunction with Windows name servers (WINS).
Description of the menu options R75 Flags Name Name of the host in the host table. Group/Domain Name of the group or domain in the group list. Groups and NT domains are handled in the same manner from the NetBIOS point of view. Type WINS type of the host. The type is not relevant for NetBIOS, but Microsoft Networks assign certain properties to the name on the basis of the type. IP-address IP address of the owner of the name. The same name can be assigned to multiple IP addresses in the group list.
English R76 Description of the menu options OS-Ver Operating system version number SMB-Ver Version number of the SMB protocol used Server-type Bit mask in which the services of the server are coded Remote-ID Name of the remote station from which the server was announced Timeout Time until the entry loses its validity (for entries from the LAN) or time until the router propagates a remote entry. Flags Corresponds to the flags in the host or group tables.
Description of the menu options R77 the time period specified here. Possible settings are from 1 to 99 minutes; The default setting is 15 minutes. This entry specifies the number of failed attempts allowed before the log-in block is activated. An empty password (simply pressing at the password prompt) is not considered an attempt and therefore does not activate the block. The default value is 5.
R78 Description of the menu options 쮿 English 쮿 EAZ/MSN(s): This option allows you to enter the call numbers to which the LANCAPI is to respond. If you wish to enter more than one number, place a semicolon between the individual numbers. Prio-out: The priority for a port controls the option for breaking outgoing connections via the LANCAPI router connections.
