Chapter Two: Getting Started 1. Installation overview 16 1. Installation overview The steps in this chapter explain how to install and configure the 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 17 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 18 Verify the configuration of your computers To connect to the DIVA LAN ISDN Modem Each computer that will be connected to the DIVA LAN ISDN Modem must have: • A 10BASE-T Ethernet network interface card, properly installed and configured to use the TCP/IP protocol. Consult the documentation that came with your card for instructions on how to do this.
Chapter Two: Getting Started 3. Choose a connection protocol 19 3. Choose a connection protocol 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 20 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 21 AO/DI incorporates BACP, and uses it to monitor incoming and outgoing traffic. When traffic volume warrants, it enables one or two B-channels to meet the demand. For information on AO/DI, see “Configuring AO/DI” on page 54. As with MLPPP, MLPPP + AO/DI reserves both B-channels for its exclusive use. This means that if your Internet connection uses MLPPP + AO/DI, you will not be able to make or receive other data calls.

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 53 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 54 4. Click the More button next to the Protocol field. You will see the following page. 5. 6. 7. 8. 9. Set the BACP parameters as required. Click Save. Click Finish. Click Save. Click Reset. Configuring AO/DI AO/DI lets you maintain a permanent connection to the Internet or a corporate network, without tying up an expensive ISDN B-channel. AO/DI accomplishes this by using the ISDN D-channel to establish a low-bandwidth (9.
Chapter Five: Minimizing ISDN Charges Configuring AO/DI • Mode: Determines ISDN line usage when AO/DI is enabled. • D-Channel Only: Data is only transferred on the D-channel. • Normal: Data is transferred on the D-channel, plus both B-channels if required. • Dial prefix: Specifies the prefix to dial when making a call. For example, 1 to call long distance, or 9 to obtain an external line • X.25 transmit queue threshold: Specifies the transmit queue threshold, in bytes, for X.25 on the D-channel.
Chapter Five: Minimizing ISDN Charges Configuring AO/DI 56 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 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 58 Setting ISDN active intervals By defining ISDN active intervals, you can 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 59 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 60 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 61 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 62 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 63 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 119.
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 Security features This 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. Network address translation (NAT) Active NAT hides the addresses of the computers on the internal Ethernet LAN from the external network.
Chapter Six: Security System password 67 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 Network address translation 68 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 69 • Only one computer on the internal LAN can be designated to receive the traffic for a specific protocol. This means, for example, you can cannot create multiple web servers or FTP servers. Default NAT server When the DIVA LAN ISDN Modem receives incoming datagrams containing protocols it does not handle, it discards them.
Chapter Six: Security Remote management 70 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 71 Consider the following topology: 150.150.5.2 150.150.5.3 150.150.5.4 150.150.5.1 Router DIVA LAN ISDN Modem B1 B2 ISDN D LINK E1 Ethernet E2 E3 E4/C FAULT POWER 192.168.1.4 192.168.1.3 Internet 192.168.1.2 192.168.1.5 Remote A ISP Incoming HTTP and Telnet traffic is allowed. 192.168.1.1 Incoming HTTP and Telnet traffic is dropped.
Chapter Six: Security Incoming data calls 72 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 73 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.
Chapter Six: Security Call screening 74 11. Click Finish. 12. Click Save. 13. Click Reset. Call screening Call screening enables you to accept or reject incoming data calls based on their phone number. This is an effective way to limit dial-in access to the DIVA LAN ISDN Modem to a small group of remote sites. To set up call screening 1. On the Manual Configuration menu, click Incoming data calls. 2. In the Define settings for box choose Call screening. You will see the following page. 3.
Chapter Six: Security Call authentication 75 To successfully use call authentication it is important that both devices are configured to support the same authentication options. To set up call authentication 1. On the Configuration main menu, click Connection Profiles. 2. Click Edit for the profile you want to configure. 3. Click Authentication on the menu bar. You will see the following page: 4.
Chapter Six: Security Callback 76 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, hangs up, then waits for the server to call back to establish the connection.
Chapter Six: Security Manual dialing 77 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 Custom security features 3. Click Connection on the menu bar. You will see the following page: 4. 5. 6. 7. Enable Manual dialing only. Click Finish. Click Save. Click Reset. Custom security features By using IP filters you can create your own custom security solutions.
Chapter Seven Setting up the Phone Ports If you purchased a DIVA LAN ISDN Modem with analog ports, you are able to use ordinary telephones, answering machines, fax machines, and modems over your ISDN line. This chapter explains how to configure the DIVA LAN ISDN Modem to support these analog devices. Also in this chapter are instructions for assigning phone numbers to phone and data ports and configuring supplementary calling services.
Chapter Seven: Setting up the Phone Ports Assigning phone numbers 80 Assigning phone numbers The DIVA LAN ISDN Modem provides flexible support for the assignment of phone numbers. Single number If you have one ISDN number, it is used for both data calls, and voice calls. When an incoming call is received, the DIVA LAN ISDN Modem will automatically determine if the call is voice or data, and route the call appropriately.
Chapter Seven: Setting up the Phone Ports Assigning phone numbers 81 • Set the main telephone number of PHONE port 1 to 555-1111 • Set the additional telephone number for PHONE port 1 to 555-3333 • Set the main telephone number of PHONE port 2 to 555-2222 In this scenario, calls placed to your mobile phone are forwarded to 555-3333 if the mobile phone is not on.
Chapter Seven: Setting up the Phone Ports Assigning phone numbers 82 2. In the Define settings for box, choose the phone port you want to define settings for. DIVA LAN ISDN Modem displays the following page: 3. Set phone numbers as follows: • Main telephone number for this port: Specify the ISDN phone number you want to assign to this port. • Additional telephone number for this port: Specify the MSN number you want to assign to this port.
Chapter Seven: Setting up the Phone Ports Connecting modems and fax machines 83 Use the third choice to specify a distinct number for data calls. For example: 4. Click Save. 5. Click Reset. Connecting modems and fax machines If you are using a PHONE port to connect an analog modem or fax machine, the DIVA LAN ISDN Modem lets you configure the port for better throughput.
Chapter Seven: Setting up the Phone Ports Call bumping 84 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 Nine: Advanced Installations IP routes 111 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 112 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 LINK Ethernet E2 E3 E1 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 113 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 114 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 115 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 116 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 117 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 • 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. If you select LAN, data is routed onto the local Ethernet LAN created by the DIVA LAN ISDN Modem. • Metric: Metric determines the weight of a route. If two identical routes exist, then the DIVA LAN ISDN Modem uses the route with the lower metric.
Chapter Nine: Advanced Installations IP filters 119 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 120 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 121 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. 7. Define the settings for the filter and click Done. The following descriptions explain the options that are available.
Chapter Nine: Advanced Installations IP filters 122 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. • outgoing: Data being sent by the DIVA LAN ISDN Modem on the ISDN link. • all: Both incoming and outgoing.
Chapter Nine: Advanced Installations IP filters 123 • DNS: Domain name system. Filtering DNS datagrams can cause disruptions in the ability to access remote sites. The following options are also available: NFS/RPC, News, Time (NTP), BOOTP, SNMP, ICMP, Ping (ICMP), Ping Reply, ICMP Redir. For a description of these protocols, consult the appropriate RFC at the site www.faqs.org. 8. Activate the filter by clicking the box that appears to the right of the EDIT button. 9. Click Save.
Chapter Nine: Advanced Installations IP filters 124 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 125 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 126
Chapter Nine: Advanced Installations Making a V.120 connection 127 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.
