Chapter Two: Getting Started 1. Installation overview 1. Installation overview The steps in this chapter explain how to install and configure DIVA LAN ISDN Modem to provide Internet access for up to four computers. The following diagram illustrates the key components that are part of this installation.
Chapter Two: Getting Started 2. Prepare for installation 18 2. Prepare for installation To ensure that the installation of your DIVA LAN ISDN Modem is quick and trouble free, take a few moments to prepare for installation.
Chapter Two: Getting Started 2. Prepare for installation 19 To configure the DIVA LAN ISDN Modem The computer you are going to use to configure the DIVA LAN ISDN Modem must have: • Web browser software (Netscape 3.01 or later, or Internet Explorer 4 or later). Internet Explorer 4 is included on the DIVA LAN ISDN Modem CD for computers running Windows 95, Windows 98, or NT 4.0 or later. NT 4.0 requires SP3 or SP4 available on the DIVA LAN ISDN Modem CD.
Chapter Two: Getting Started 3. Choose a connection protocol 20 3. Choose a connection protocol The usage of the ISDN link is governed by the type of connection protocol you choose. The connection protocol defines the rules by which ISDN channels are enabled and disabled. The type of protocol you choose to use depends on the type of connections you plan to make. Important ISDN concepts Before you can decide on a connection protocol, you must become familiar with the following ISDN concepts.
Chapter Two: Getting Started 3. Choose a connection protocol 21 Choosing a connection protocol Since the DIVA LAN ISDN Modem supports so many potential connections, a set of rules is needed to control how the two ISDN B-channels are shared between connections. These rules are based on the type of connection protocol you decide to use for your data traffic. The DIVA LAN ISDN Modem supports the two protocols: PPP and V.120. • PPP is a widely-used standard for transferring data on point-to-point links.
Chapter Two: Getting Started 3. Choose a connection protocol 22 Only one PHONE port can be used when an MLPPP + BACP connection is active. However, since MLPPP + BACP may only be using one B-channel, either PHONE 1 or PHONE 2 may not be available. For example, if PHONE 2 was in use when the data connection was established, the data connection uses telephone number 1. Even though telephone number 2 becomes available when PHONE 2 hangs up, the data connection does not switch over.
Chapter Two: Getting Started 4. Order an ISDN Line 23 4. Order an ISDN Line Call your local phone company and order an ISDN Basic Rate line. To make ordering an ISDN line easier, Bellcore, in conjunction with the North American ISDN User’s Forum (NIUF) and Local Exchange Carriers (LEC), have created several pre-defined ISDN packages which you can order by simply specifying an ISDN ordering code (IOC).

Data call thresholds By defining data call thresholds, you are able to limit the total number of calls or total length of calls made by any one profile during a set period of time. This is especially useful as a safety measure if you have devices that may inadvertently generate a large number of calls or may stay connected indefinitely.
Chapter Five: Minimizing ISDN Charges Configuring BACP 61 Configuring BACP The bandwidth allocation protocol (BACP) works in conjunction with the MLPPP connection protocol to regulate usage of your ISDN line. The DIVA LAN ISDN Modem uses BACP to monitor incoming and outgoing traffic, and to open or close the second ISDN B-channel as the traffic volume warrants. This reduces your communications charges by ensuring that two ISDN channels are never active when one is sufficient.

Chapter Five: Minimizing ISDN Charges Configuring AO/DI 65 X.25 on the D-channel During normal ISDN operation, the D-channel is used for signalling traffic purposes (call setup, call take down, caller ID, etc.) However, the full bandwidth of the D-channel is not needed for this. AO/DI takes advantage of the extra 9.6 bps that is available to establish an X.25 packet-switched connection to a remote site. Therefore, to take advantage of AO/DI, the remote site must support X.
Chapter Five: Minimizing ISDN Charges Configuring AO/DI 3. Click Finish. 4. Click Save. 5. On the Manual configuration menu, click X.25. The DIVA LAN ISDN Modem displays this page: 6. Set the X.25 parameters as required. 7. Click Save. 8. Click Reset.
Chapter Five: Minimizing ISDN Charges Setting ISDN active intervals 67 Setting ISDN active intervals By defining ISDN active intervals, you are able to place restrictions on when data calls can be made or received. To set ISDN active intervals 1. On the Manual configuration menu, click ISDN active intervals. 2. For each interval specify the day of the week it applies to, and the starting and ending times. Make sure you set the system clock, so the time and date on the DIVA LAN ISDN Modem are accurate.
Chapter Five: Minimizing ISDN Charges Spoofing NetBIOS services 68 Spoofing NetBIOS services The NetBIOS protocol is used by Windows 95/98/NT to support Microsoft Windows Network Neighborhood, the MAP NETWORK option in Windows Explorer, and various DOS-based networking commands (such as net use, net view, and net logon). To maintain these services, NetBIOS regularly exchanges bookkeeping messages between connected systems.
Chapter Five: Minimizing ISDN Charges Data compression 69 Data compression Data compression increases the effective throughput of a B-channel by encoding data so that fewer bits are required to represent it. Popular compression algorithms typically reduce the size of the data by 50 percent, effectively doubling the rate at which it is transmitted. However, not all types of data lend themselves to such high compression ratios.
Chapter Five: Minimizing ISDN Charges Manual dialing 70 Manual dialing ISDN active intervals lets you control costs by specifying time ranges when the ISDN link can be used. However, there may be certain situations where direct control of the ISDN link is desirable. The manual dialing option gives you this control. Each profile can be configured to use manual dialing only.
Chapter Five: Minimizing ISDN Charges Restricting analog calls 71 Restricting analog calls Generally, most of the activity on the ISDN line will be created by data traffic. That is why the most of the settings in this section are targeted at data calls. However, in some cases, you may want to place some restrictions on analog use of the ISDN line. Each phone port has a type of calls setting which you can use for cost control purposes.
Chapter Five: Minimizing ISDN Charges Data over voice 72 Data over voice In some regions, ISDN voice calls cost less than ISDN data calls. You can configure the DIVA LAN ISDN Modem to take advantage of this discrepancy to reduce your ISDN charges. When you enable data over voice support, the DIVA LAN ISDN Modem establishes all data calls as voice calls. This does not affect the throughput of your call, the only change is in how the call is billed.
Chapter Five: Minimizing ISDN Charges Traffic filtering Traffic filtering By using the DIVA LAN ISDN Modem’s IP filters, you can selectively drop outgoing traffic to reduce your communications charges. This can be useful if you have applications on your LAN that regularly send non-critical traffic across the ISDN link. For more information on filters, see “IP filters” on page 128.
Chapter Six Security Connecting your computers to the internet or a remote corporate LAN creates a wide range of benefits, but also exposes your computers to certain risks. To safeguard your data and systems, the DIVA LAN ISDN Modem provides a comprehensive range of security features. This chapter explains how to use and configure each feature for optimal protection of your systems.
Chapter Six: Security Security features 75 Security features The following table lists all security features offered by the DIVA LAN ISDN Modem, and their default settings. Feature Default Description System password None Restricts access to the DIVA LAN ISDN Modem configuration interfaces. Automatic log out Active Automatically terminates idle configuration sessions.
Chapter Six: Security System password 76 System password The DIVA LAN ISDN Modem provides a system password that restricts access to the Web-based configuration interface and the CLI. This ensures that configuration changes can only be made by authorized personnel. By default, no password is defined. To set the system password 1. On the Manual Configuration menu, click System. 2. Enter the system password in the Login Password and Repeat Login Password fields. 3. Click Save. 4. Click Reset.
Chapter Six: Security Automatic log out 77 Automatic log out The DIVA LAN ISDN Modem applies an automatic time out to configuration sessions. When a configuration session is idle for more than the time out value, the DIVA LAN ISDN Modem automatically logs the user out. This reduces the risk of unauthorized persons taking advantage of a logged-in computer that has been left unattended. Time outs are not configurable and are set as follows: • If you are using the web interface, the time out is 30 minutes.
Chapter Six: Security Network address translation 78 Network address translation The DIVA LAN ISDN Modem uses network address translation (NAT) to “hide” the local LAN it creates from all external resources. The benefits of this are the ability for all connected computers to access the Internet using one Internet address and ISP account. For example, when communicating with the Internet, these four computers share the dynamically assigned address 222.182.22.39. 192.168.1.5 192.168.1.4 192.168.1.
Chapter Six: Security Network address translation 79 Default NAT server When the DIVA LAN ISDN Modem receives incoming datagrams containing protocols it does not handle, it discards them. For example, if an incoming datagram contains an FTP request and no FTP server has been defined using a static mapping, the data is discarded. In some cases, you may want to forward these datagrams to a specific computer. The DIVA LAN ISDN Modem calls this computer, the default NAT server.
Chapter Six: Security Network address translation To create a static NAT mapping 1. On the Manual Configuration menu, click IP. 2. On the IP menu, click NAT Static Mappings. 3. For each server that you want to define, specify the following parameters: • Protocol: Select the protocol that remote computers will use to access the server. • Server port: Enter the port number that the protocol will use on the server. • Server address: Enter the IP address of the computer that will act as the server.
Chapter Six: Security Remote management 81 Remote management By default, the DIVA LAN ISDN Modem does not allow remote devices to access its configuration interfaces via the ISDN link. This prevents unauthorized tampering when the DIVA LAN ISDN Modem has dialed out and is connected to the Internet or a remote corporate network. To accomplish this security, all incoming HTTP and Telnet traffic on the ISDN line is automatically dropped.
Chapter Six: Security Remote management 82 To enable remote management If you want to support remote configuration, you must enable the remote management option. This option can only be set with the web-based configuration interface. 1. On the Manual Configuration menu, click System. 2. Check the Enable remote management check box. 3. Click Save. 4. Click Reset. Note Is is strongly suggested that you define a log in password if you enable remote management.
Chapter Six: Security Incoming data calls 83 Incoming data calls By default, the DIVA LAN ISDN Modem refuses all incoming ISDN data calls. This effectively shuts the door on unauthorized systems dialing-in. (Voice calls are not blocked by this setting.
Chapter Six: Security Incoming data calls 84 Notes on the diagram 1. The DIVA LAN ISDN Modem provides an IP address to the remote computer. 2. Both the DIVA LAN ISDN Modem and the remote computer have their own fixed IP addresses so no assignments are made. 3. Both the DIVA LAN ISDN Modem and the remote computer have their own fixed IP addresses AND have specified remote addresses. This means they will only be able to connect if the remote addresses match the IP addresses of the other device. 4. 5. 6.

Chapter Six: Security Call authentication 87 Call authentication Call authentication enables ISDN devices, like the DIVA LAN ISDN Modem, to validate the identity of the device at the other end of the line. Authentication works through the exchange of usernames and passwords. It can be one-way (either the caller gets validated or the callee gets validated) or two-way (both sides validate each other). Generally, authentication is one-way, with the caller getting validated.
Chapter Six: Security Callback 88 Callback Callback is another effective method to control access to the DIVA LAN ISDN Modem. When callback is enabled, the DIVA LAN ISDN Modem functions as a callback client, and the remote site being called functions as a callback server. The client calls the server, the connection is dropped or disconnected, then waits for the server to call back to re-establish the connection.
Chapter Six: Security Callback 89 Delay before host calls back This option is only supported by the callback control protocol. It allows you to specify the amount of time the server waits before calling back. The DIVA LAN ISDN Modem proposes the delay during callback negotiation. The server can either accept or reject it. Timeout waiting for callback Sets the amount of time the DIVA LAN ISDN Modem waits for the server to call back.
Chapter Six: Security Manual dialing 90 Manual dialing The DIVA LAN ISDN Modem automatically establishes the ISDN link whenever there is outgoing data traffic. There may be certain situations where this is not desirable and you will want to have manual control of ISDN usage. The manual dialing option gives you this control. Each profile can be configured to use manual dialing only.
Chapter Six: Security Custom security features Custom security features By using IP filters you can create your own custom security solutions. For example: • limiting local access to the DIVA LAN ISDN Modem for certain computers • accepting incoming traffic only from certain remote users or networks • dropping incoming or outgoing nuisance traffic For more information see “IP filters” on page 128.

To enable support for fax/modem 1.
Chapter Seven: Setting up the Phone Ports Call bumping 95 Call bumping Call bumping, more formally known as dynamic bandwidth allocation (DBA), allows you to share the ISDN line between data and analog calls. This enables you to send and receive faxes, or make phone calls, while at the same time downloading data from the Internet with your computers.
Chapter Seven: Setting up the Phone Ports Restricting analog calls 96 Restricting analog calls Generally, most of the activity on the ISDN line will be created by data traffic. That is why the most of the settings in this section are targeted at data calls. However, in some cases, you may want to place some restrictions on analog use of the ISDN line. Each phone port has a type of calls setting which you can use for cost control purposes.
Chapter Seven: Setting up the Phone Ports Supplementary services 97 Supplementary services The supplementary services described in this section only work if they are supported by your ISDN service provider and if they are enabled on your ISDN line. Contact your ISDN service provider for more information on the calling features that are available in your area and the provisioning of your ISDN connection.
Chapter Seven: Setting up the Phone Ports Supplementary services 98 If your ISDN service conforms to EZ-ISDN 1A or EZ-ISDN 3A, you will also have VoiceMail. If the number to which you have forwarded your calls is busy or does not answer, the call will automatically be forwarded to your VoiceMail. With VoiceMail, the DIVA LAN ISDN Modem also supports Visual Message Waiting Indicator. Call Forwarding supports Reminder Ring.
Chapter Seven: Setting up the Phone Ports Supplementary services 99 Call Transfer Call Transfer allows you to disconnect from a Three-Way Conference call and leave the other two people connected. It works as follows: Establish a Three-Way call as described in the section above. Hang up. The other two people remain connected.

This section explains how to install and configure such a setup. Selecting a connections protocol One of the primary considerations is choice of connection protocol.
Chapter Nine: Advanced Installations IP routes 120 IP routes This section provides background information on why IP routes are needed and explains how to define them. However, before you can understand routing, you must be familiar with IP addressing and how the DIVA LAN ISDN Modem assigns them. About IP addresses IP addresses identify the computers (and other devices) on an IP network. Each address is composed of 32 bits.
Chapter Nine: Advanced Installations IP routes 121 The following diagram shows four computers with addresses assigned by the DIVA LAN ISDN Modem. 192.168.1.5 192.168.1.4 192.168.1.3 192.168.1.2 LAN interface 192.168.1.1 DIVA LAN ISDN Modem B1 B2 ISDN D E1 LINK Ethernet E2 E3 E4/C FAULT POWER DIVA LAN ISDN Modem By default, the DIVA LAN ISDN Modem uses the mask 255.255.255.0 when assigning addresses. This means that the network portion of the address is: 192.168.1.
Chapter Nine: Advanced Installations IP routes 122 In some cases, you may be required to assign a static IP address to a profile. This may occur when connecting to a corporate network. For example: 192.168.1.5 192.168.1.4 192.168.1.3 Internet 192.168.1.2 ISP ISP profile Address dynamically assigned by ISP 192.168.1.1 222.182.22.39 B-channel 201.163.1.
Chapter Nine: Advanced Installations IP routes 123 Why routes are needed Data on an IP network is carried in small packages called datagrams. Each datagram contains the IP address of its source and destination. In order to send datagrams to their proper destination, the DIVA LAN ISDN Modem requires a list of destinations and the addresses that are associated with it. This information is stored in a route. Since more than one route is generally required, they are grouped together in a routing table.
Chapter Nine: Advanced Installations IP routes 124 Multiple connections Consider the following scenario, which features an Internet and Corporate connection, each using one B-channel (PPP): 192.168.1.5 192.168.1.4 192.168.1.3 Internet 192.168.1.2 ISP ISP profile Address negotiated with ISP 192.168.1.1 212.182.22.39 B-channel 201.163.1.
Chapter Nine: Advanced Installations IP routes 125 Routing on the local LAN The DIVA LAN ISDN Modem lets you create your own local area network. In some instances, this network, or the DIVA LAN ISDN Modem itself, will be connected to another network via a bridge or router. Consider this scenario, which adds another LAN to the previously discussed example: 150.150.5.2 150.150.5.3 150.150.5.4 150.150.5.1 192.168.1.4 192.168.1.3 Internet 192.168.1.2 192.168.1.
Chapter Nine: Advanced Installations IP routes 126 The Routing Information Protocol (RIP) RIP permits the DIVA LAN ISDN Modem to automatically discover routes for itself, by listening to routing broadcasts from other networks. If your corporate LAN broadcasts RIP updates, the DIVA LAN ISDN Modem will be able to discover routes to all subnets connected to it.
Chapter Nine: Advanced Installations IP routes • Gateway address: Only used if the Interface is set to LAN. This is the address of the device you want to send the routed traffic to. This will usually be the address of a bridge or router. • Interface: Choose the name of the profile you want to send the routed data to. The profile you choose should establish a connection to the proper destination so that routing is successful.
Chapter Nine: Advanced Installations IP filters 128 IP filters IP filtering provides you with the means to implement customized security, usage, and cost control measures. How filtering works Filters are defined in a stack. Up to 8 filters can be combined together to obtain sophisticated results.
Chapter Nine: Advanced Installations IP filters 129 Default filters By default, the DIVA LAN ISDN Modem defines the following three filters for the ISP profile: The first two filters prevent outside access to the web-based configuration interface and the CLI by discarding incoming HTTP and Telnet traffic. When you enable remote management, these filters are deleted. The last filter is required because, by default, any traffic that is not forwarded is discarded when it reaches the bottom of the stack.
Chapter Nine: Advanced Installations IP filters 130 4. Click Filters to display the following page. (If you enabled remote management you will not see the first two filters.) 5. Select the profile you want to define filters for. 6. Click a “+” symbol to insert a new filter. The DIVA LAN ISDN Modem displays the Edit Filters page.
Chapter Nine: Advanced Installations IP filters 131 7. Define the settings for the filter and click Done. The following descriptions explain the options that are available. Source /Destination Action Direction Address Location Protocol Action • Drop: Discard data that matches the filter definition. • Forward: Send data that matches the filter definition to the filter output. Direction • incoming: Data being received by the DIVA LAN ISDN Modem on the ISDN link.
Chapter Nine: Advanced Installations IP filters 132 • any well known: Applies the filter to any protocol using TCP or UDP ports in the range 0 to 1023. See RFC 1700 for the complete list of protocols. • UNIX: Applies the filter to any protocol using TCP or UDP ports in the range 512 to 1023. See RFC 1700 for the complete list of protocols. • TCP: Many protocols (such as HTTP, FTP, Telnet, News) make use of TCP. If you filter all TCP traffic you will prevent the use of these protocols.
Chapter Nine: Advanced Installations IP filters 133 When done, the filter stack should look like this: Allowing incoming traffic only from a specific network This example shows how to allow the DIVA LAN ISDN Modem to only receive incoming data from a specific network (112.111.212.0) on the Internet. Data from all other networks is dropped. However, outgoing traffic is not affected. This requires defining two filters.
Chapter Nine: Advanced Installations IP filters 134 When done, the filter stack should look like this: Blocking web surfing This example shows how to block computers on the local LAN created by the DIVA LAN ISDN Modem from surfing the web. Web traffic is carried by the HTTP protocol. Therefore, to stop web access, this protocol needs to be dropped for all outgoing traffic. A single filter needs to be defined. Place this filter in the third position in the stack.
Chapter Nine: Advanced Installations When done, the filter stack should look like this: IP filters 135
Chapter Nine: Advanced Installations Making a V.120 connection 136 Making a V.120 connection V.120 was designed to allow non-ISDN devices to communicate with the ISDN network. The DIVA LAN ISDN Modem provides support for V.120, so you can connect with such legacy systems. For example, in many countries around the world, Compuserve offers access to their network over ISDN, using the V.120 protocol. In general, you should use V.120 only when the site you are connecting to requires it. Once the V.
