System Requirements This chapter describes how to connect a single computer to the Eicon 1550/1551. Before you begin, review the system requirements, as outlined below. For LAN setup instructions, see LAN Setup on page 30. Networking Requirements When connecting the Eicon 1550/1551 directly to a computer, the following is required: • A 10Base-T Ethernet network interface card, properly installed and configured to use the TCP/IP protocol.
Step 1: Connect the Cables This procedure will describe how to connect one computer to the Eicon 1550/1551, once the set-up is running correctly. You can then connect up to three other LAN devices. Your Eicon 1550/1551 package includes one Ethernet cable (the blue cable). This is a standard, straight-through cable. If you plan to connect more than one computer to the Eicon 1550/1551, you will need to acquire a separate standard Ethernet cable for each piece of equipment.
Procedure Leave your computer on during installation. 1. Connect the power adapter. When connected, the Power indicator light (on the front of the device) should turn on. 2. Connect your VHSI cable. Connect the appropriate end of the cable to the VHSI port of the Eicon 1550/1551 then connect the other end to your modem or leased line connector. Note: VHSI cables are not included with your Eicon 1550/1551.
Step 2: Log in to the Eicon 1550/1551 Whenever you wish to change settings on the Eicon 1550/1551, you must first log in using a web browser, as shown below. 1. Launch your web browser. 2. Click ‘File’, ‘Open’, then enter the following IP address: 192.168.1.1 3. Click ‘OK’. You should see the ‘Log in’ page. Note: If you do not see the ‘Log in’ page, see Troubleshooting on page 17. 4. Click the ‘Log in’ button. Note: By default there is no password.
5. The main menu should appear, as shown below. 6. See Step 3: Select the VHSI Protocol on page 19. Troubleshooting If you cannot access the ‘Log in’ page: • Verify that all cables are connected properly. The power and Ethernet lights should be on. • Verify that your web browser is configured to use the LAN and not a dial-up connection, and that your browser is not set to use a proxy server. See Adjusting Browser Settings (below) for instructions on how to do this.
• Internet Explorer previous to version 5: – From the ‘View’ menu, select ‘Internet Options’, then click the ‘Connection’ tab. – Verify that ‘Connect to the internet using a local area network’ is enabled. – Verify that the ‘Proxy Server’ option is disabled. • Netscape Navigator (do one of the following): – Under Options, click ‘Network Preferences’, then ‘Proxies’. Verify that the ‘No Proxies’ option is selected. – Under the ‘Edit’ menu, click ‘Preferences’, ‘Advanced’, then ‘Proxies’.
Step 3: Select the VHSI Protocol Before you begin creating connection profiles, including any backup profiles, you should verify the protocol setting for the VHSI port (set to ‘X.25’ by default). This is due to the fact that all connection profiles are deleted when the protocol is changed. Note: Configuration settings can be saved to a file on your hard drive. This is useful if you have many connection profiles already defined but need to change the VHSI protocol.
Step 4: Create Profiles Settings for particular connections are contained in profiles on the Eicon 1550/1551. Note: When you change protocols for the VHSI interface, all profile information is lost. To avoid having to re-enter configuration information, choose the protocol first, as described in Step 3: Select the VHSI Protocol on page 19. As profiles contain many settings, you may find it useful to fill out the Configuration Worksheets on page 142 in order to determine your settings before making changes.
3. The settings for your new profile will be displayed, along with configuration parameters. The parameters available will differ depending on the protocol used. For more information, see Creating and Editing Profiles on page 49. 4. Make the required changes to the profile. Be sure to scroll down and inspect all parameters. Note: On line help is available by clicking on the setting names (in blue). 5. Click the ‘Save’ button (located at the bottom right of the page) when finished.
Limits on Creating Profiles If the VHSI protocol is set to X.25, you can create up to 32 connection profiles. When set to Frame Relay, you can create up to eight connection profiles. When using PPP as the VHSI port protocol, you may only create one profile. Note: It is not recommended to mix Frame Relay and X.25 profiles. It is recommended that you either create all X.25 (with or without ISDN) or all Frame Relay (with or without ISDN) profiles.
Step 5: Modify Other Settings Changes that you have made thus far do not take effect until you reset the device. However, it is strongly recommended that you check other device settings to ensure that they correspond to your network situation. Specifically, you should inspect the following pages: • All VHSI Port settings. The ‘VHSI Port’ group of settings includes the ‘VHSI Port’ link itself, the ‘Protocol’ page (which includes a second page, ‘HDLC’, when the protocol is set to X.
• Clicking a setting name displays context-sensitive help. Online help window What’s Next? See Step 6: Reset the Device and Test WAN Access on page 25.
Step 6: Reset the Device and Test WAN Access For your settings to take effect, you must reset the device by clicking the ‘Reset Device’ button at the top of the browser window. ‘Reset Device’ button Once you have reset the device, test that you have access to the remote device using your WAN application. You can also ping the remote device to which you are attempting to connect. When the VHSI connection is working properly, the VHSI port indicator light should stay solid.
Creating a Backup Profile The ISDN port on the Eicon 1551 is designed to act as a backup connection in case the VHSI connection is unavailable. However, any profile, including a separate VHSI connection profile, can act as a backup for any other profile. The following example demonstrates a simple scenario on the Eicon 1551. Two profiles have been created: VHSI-main and ISDN-backup. On the profile page for ‘VHSI-main’, the profile ‘ISDN-backup’ has been defined as the backup profile for ‘VHSI-main’.
ISDN Port Setup This section describes how to configure the ISDN port on the Eicon 1551. This port was designed to act as a backup port in case the main VHSI connection becomes unavailable. Connecting the ISDN Cable The gray cable included with your Eicon 1551 package is used to connect the ISDN port to your ISDN wall jack (or NT-1, depending on how your ISDN line is set up). However, any standard, straight-through RJ45-RJ45 cable can be used.
5. Click the ‘ISDN Port’ link to bring up the ‘ISDN Port Parameters’ page. 6. Specify the switch type. 7. Enter your ISDN phone numbers in the ‘Numbers’ area. If you only have one number, enter it in both number fields. 8. If you know the billing intervals for your ISDN line, enter them in the appropriate fields. The ‘Initial Billing Interval’ is the minimum amount of time you want an ISDN channel to be open.
Configuring the ISDN Protocol The connection protocol, set to ‘PPP’ by default, governs the rules by which ISDN channels are enabled and disabled. For more information on these settings, see ISDN Menu > Protocols on page 124. 1. Expand the ‘ISDN Port’ group of settings by clicking on the small ‘+’ 2. Click on the ‘Protocol’ link. The ‘ISDN Protocol’ page will appear. 3. Click on the radio button next to your protocol of choice. 4. Click ‘Save’.
LAN Setup To give more than four computers access to the external network, the Eicon 1550/1551 can be connected to a network hub and become part of a Local Area Network (LAN). To do this, you must use an Ethernet crossover cable (not included) to connect your hub to any of the four Ethernet ports on the Eicon 1550/1551. You can also use a standard Ethernet cable if your hub has an uplink or cascade port. This section provides general guidelines for connecting the Eicon 1550/1551 to a LAN.
• Once you have contacted the Eicon 1550/1551, you should first change the LAN IP address (set to 192.168.1.1 by default) of the Eicon 1550/1551 to an IP address that is appropriate for your LAN. Depending on your LAN requirements, this may or may not be necessary. For example, if the Eicon 1550/1551 will be acting as your DHCP server, it is probably not necessary to change the device’s LAN IP address, as all computers making DHCP requests will be given a 192.168.1.x IP address.
General Setup Procedure The following is a general setup procedure for connecting the Eicon 1550/1551 to a LAN. 1. Connect the power adapter and VHSI cable as described in Step 1: Connect the Cables on page 14. 2. Using an Ethernet crossover cable (sold separately), connect the Eicon 1550/1551 to your network hub, if available. If your hub has an uplink or cascade port, you can also use a standard Ethernet cable (included). 3.
• Your computers have fixed IP addresses: In this case, you must change the Eicon 1550/1551’s IP address so that it corresponds to what is available on your network. Otherwise, the Eicon 1550/1551 may not be accessible from the computers on your LAN. To change the LAN IP address: 1. From the menu, click ‘LAN’. The Eicon 1550/1551 displays the LAN parameters page. 2. Modify the ‘IP address’ and ‘Subnet Mask’ settings to addresses appropriate for your LAN. ‘IP address’ and ‘Subnet Mask’ settings 3.
Disabling DHCP (if required) If your LAN has an existing DHCP server, you should disable the Eicon 1550/1551’s DHCP server. This ensures that the Eicon 1550/1551 will not respond to DHCP requests. Note: The Eicon 1550/1551 automatically de-activates its own DHCP server if an existing DHCP server is detected. To re-activate this feature, remove the existing server from the LAN and reset the Eicon 1550/1551. To disable the DHCP server: 1.
Changing TCP/IP Settings to DHCP For most connection scenarios, your computer must have TCP/IP configured to act as a DHCP client. This allows your computer to dynamically acquire its IP address and other settings from the Eicon 1550/1551. Note: If you do not want to use the Eicon 1550/1551’s DHCP feature, you must change the IP address of your computer to 192.168.1.2, or 192.168.1.3, etc., as the default IP address of the Eicon 1550/1551 is 192.168.1.1.
TCP/IP Settings for Windows NT 4.0 The following procedure describes how to install TCP/IP on Windows NT 4.0. Note that if you have more than one Ethernet adapter installed on your system, you must only change the settings for the adapter used by the Eicon 1550/1551. 1. Click ‘Start’, ‘Settings’, ‘Control Panel’. 2. Double-click the ‘Network’ icon. The Network dialog box appears. 3. Click the ‘Protocols’ tab. 4. If ‘TCP/IP’ is not listed, you must install it, as described below.

Security Features Summary Connecting your computers to an external network creates a wide range of benefits, but also exposes your computers to certain risks. To safeguard your data and systems, the Eicon 1550/1551 provides a comprehensive range of security features. This section explains how to use and configure each feature for optimal protection of your systems. This table lists all security features offered by the Eicon 1550/1551, and their default settings.
The following table lists the security features that can be applied to restrict access to the Eicon 1550/1551 configuration interfaces.
System Password The Eicon 1550/1551 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. Setting a System Password 1. From the menu, click ‘System’. 2. Enter the new system password in the ‘Login Password’ and ‘Repeat Login Password’ fields. ‘Password’ fields 3. Click ‘Save’ then ‘Reset Device’.
Automatic Log Out The Eicon 1550/1551 applies an automatic timeout to configuration sessions. When a configuration session is idle for more than the timeout value, the Eicon 1550/1551 automatically logs the user out. This reduces the risk of unauthorized persons taking advantage of a logged-in computer that has been left unattended. The timeout values, which are not configurable, are as follows: • Web interface: 30 minutes. • Telnet session: 2 minutes.
Network Address Translation (NAT) The Eicon 1550/1551 uses network address translation (NAT) to ‘hide’ the local LAN from all external resources. The benefits of this are the ability for all connected computers to access the external network using one user account, defined on the device itself. For example, when communicating with the external network, the four computers in the following diagram share the IP address ‘222.182.22.39’. 192.168.1.5 192.168.1.4 192.168.1.3 192.168.1.2 HUB LAN interface 192.
When you create a NAT static mapping, the Eicon 1550/1551 routes all traffic for the protocol you specify to the designated computer. This includes traffic normally handled by the Eicon 1550/1551 itself. This leads to the following restrictions: • Remote access to the configuration interfaces on the Eicon 1550/1551 via the external network can be disrupted. For example, if you designate a computer to receive HTTP traffic, remote access to the web configuration interface will be disrupted.
To define a default NAT server, enter the IP address of the device that should receive these datagrams into the ‘Default NAT server’ field on the IP Parameters panel. ‘Default NAT Server’ field Note: The Eicon 1550/1551 handles traffic with the following protocols: HTTP, Telnet, TFTP, ECHO (UDP port 7), and SNMP. Only traffic that does not contain these protocols will be forwarded to the default NAT server. To forward the aforementioned protocols you must define a NAT static mapping for each one.
Remote Management By default, the Eicon 1550/1551 does not allow remote devices to access its configuration interfaces via the external network. This feature can be enabled; however, this does not affect traffic on the local LAN created by the Eicon 1550/1551. If the local LAN is connected to other networks, these computers will continue to have access to the Eicon 1550/1551, even if remote management is disabled.
Enabling Remote Management To enable remote management: 1. From the menu, click ‘System’. 2. Check the ‘Enable remote management’ check box. ‘Enable remote management’ option 3. Click ‘Save’ then ‘Reset’. Defining a Password If remote management is enabled, it is strongly suggested that you define a login password. This parameter is available on the same page as the remote management option.
Authentication (PPP only) Authentication works through the exchange of usernames and passwords. This process can be one-way (either the caller or callee gets validated) or two-way (both sides validate each other). Generally, authentication is one-way, with the incoming connection being validated. For example, when the Eicon 1550/1551 connects to a device on the external network, the Eicon 1550/1551 is authenticated by the remote device, i.e.
Manual Dialing The Manual Dialing feature lets you manually control when the connection is to be established. Enabling Manual Dialing 1. From the menu, click ‘Connection’. If required, select the desired profile. 2. Scroll down to the ‘IP’ section of the page. ‘Manual Dialing’ option 3. Check the ‘Manual Dialing’ option. 4. Click ‘Save’, then ‘Reset Device’. 5. Click ‘Connection’ from the menu, select the desired profile and click ‘dial’.
Custom Security Features using IP Filters By using IP filters you can create your own custom security solutions. For example, you can limit local access to the Eicon 1550/1551 for specific computers, accept incoming traffic only from certain remote users or networks, or drop incoming or outgoing nuisance traffic. • • • • • How Filtering Works................................................................................ 63 Defining a New Filter..............................................................
Important Notes on Filters • Profile information is not retained when the protocol (PPP or X.25) is changed. Since filters apply to individual profiles, filter information is also lost when the protocol is changed. Be sure that you have set up the Eicon 1550/1551 with the proper protocol, and that you have created all the necessary profiles, before creating filters. • If you create a new profile, then wish to add filters for the profile, you must first reset the device.
4. If you have more than one profile available, select a profile from the drop-down menu (next to ‘Edit Filters for’). ‘Profile’ list 5. To insert a new filter, click the ‘+’ symbol. ‘Plus’ symbol 6. The ‘Edit IP Filters’ page appear. 7. Define the settings for the filter using the drop-down menus and click ‘Done’. The following diagram shows a quick description of what each field means. For more details on the available options, see ‘Edit Filters’ Page Options on page 66. 8.
9. Once you click ‘Done’, you are returned to the main filter page. The new filter you just defined is shown in the list. However, the checkbox to the left of the filter definition is empty, indicating that the filter is not enabled. The new filter 10. Enable the filter by clicking the box that appears to the right of the ‘Edit’ button. Checkbox 11. Click ‘Save’. This makes the filter operational.
Source / Destination • ‘from’: Examine the source IP address of the datagram. • ‘to’: Examine the destination IP address of the datagram. Location • ‘the Ethernet LAN’: Sets the filter to match datagrams with network addresses that are the same as that of the Eicon 1550/1551. By default, this is 192.168.1.0. A mask of 255.255.255.0 is used to extract the network address. • ‘the network’: Sets the filter to match datagrams with network addresses that are the same as the one you specify.
• ‘TFTP’: The Eicon 1550/1551 can function as a TFTP server to support uploading and downloading of configuration files. If you filter TFTP traffic, you will not be able to use this feature. • ‘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.
However, the moment you create one filter, a new default is used that drops all traffic, as shown below. New default filter This situation will usually require that you create at least one filter before the last filter. The new filter would forward legitimate traffic; all other traffic would be dropped by the last filter. For example, if you wanted to bar all incoming and outgoing web traffic, but allow all other traffic, the filter stack would resemble the following: 1.
After creating the first filter, the filter page should look like this: First filter Since the Eicon 1550/1551 automatically changed the last filter to one that drops all traffic, you must create a second filter (before the last one) that allows all other traffic through, as shown below. Without the second filter, all traffic would essentially be barred.

This is the most economical solution. • None: All NetBIOS traffic is discarded.
Routes Menu (IP Tree) Network Address Defines the IP address of a network where data should be routed. This address is compared against the destination address of all IP datagrams that pass through the Eicon 1550/1551. If a match is found, the IP datagram is routed to the profile you specify under Interface. Data is transported in frames on an Ethernet LAN or packets on an X.25 network. This is similar to datagrams on TCP/IP networks. Mask Length Defines the mask associated with the network address.
Interface Defines the profile that will be used to route data. The profile you choose should establish a connection to the proper destination so that routing is successful. If you select LAN, data is routed to the gateway address you specify, which must be reachable on the local Ethernet LAN created by the Eicon 1550/1551. Select NONE to disable the route. Metric Metrics determine the weight of a route. If two identical routes exist, then the Eicon 1550/1551 uses the route with the lower metric.
Filters Menu (IP Tree) Edit filters IP filtering provides you with the means to implement customized security, usage, and cost control measures. For example, you can define filters to do the following: • Drop all data from a specific address or network. • Only accept data from a specific address or network. • Drop traffic from an application to limit usage charges. Filters are defined in a stack. Up to 8 filters can be combined together to obtain sophisticated results.
NAT Mapping Menu (IP Tree) NAT must be enabled for each profile. Default NAT Server Defines the IP address of the device where all unresolved datagrams should be forwarded. Protocol Defines the protocol that is used. Choices: • UDP: The server uses the UDP protocol. • TCP: The server uses the TCP protocol. Server Port Defines the TCP or UDP port the server uses. For example, if you are setting up an SMTP server, set Protocol to TCP and Server port to 25 (25 is the conventional SMTP port).
