Internet Server User’s Guide 1 I NTRODUCTION This chapter introduces the DP-692 internet server, as well as some of the technology that is utilized. Product Description The DP-692 internet server is designed to give multiple, networked PCs access to the internet through a single account. It controls your Local Area Network (LAN) by automatically assigning IP addresses to all computers connected to it and routing traffic to and from local computers and the internet.
Internet Server User’s Guide ♦ Internet protocol support for: PPP, PAP/CHAP, NAT, TCP/IP, DHCP, ARP, ICMP, FTP, Telnet, and HTTP. ♦ Support for device configuration via Telnet, web browser, or IS Admin program (included).
Internet Server User’s Guide PC Single Global IP Address (single end user) 176.220.22.1 Using an internet server allows a single global IP address to be shared by multiple end nodes simultaneously. In this implementation, it is only necessary to pay for a single internet account even though many people will be able to use it.
Internet Server User’s Guide Non-Internet Implementations An internet server can also be used to expand a LAN by creating a localized IP “sub-group”. In this LAN-to-LAN configuration, the internet server links the two IP subgroups (as shown below). This implementation is useful when the LAN has run out of IP addresses.
Internet Server User’s Guide Introduction 5
Internet Server User’s Guide 2 I NSTALLATION This chapter provides information on the unpacking and initial installation of your internet server. Unpacking Open the shipping carton of your internet server and carefully unpack the contents. The carton should contain the following items: ♦ One internet server device ♦ One AC power adapter, suitable for your areas electrical power connections ♦ One 3.5” diskette with IS Admin software ♦ IS Admin User’s Guide ♦ One 3.
Internet Server User’s Guide Inspect the device and all accompanying items. If any item is damaged or missing, report the problem immediately to your dealer. Desktop / Shelf Installation The unit has rubber feet attached to the bottom to cushion it. Allow enough ventilation space between the device and the objects around it. Choose a sturdy, level surface in a ventilated area that is dust free and away from heat vents, warm air exhaust from other devices and direct sunlight.
Internet Server User’s Guide DP-692 Rear Panel RJ-45 – LAN The internet server has ten, 10BASE-T, RJ-45 LAN ports. These MDI-X UTP ports are 10Mbps capable and designed for use in an Ethernet LAN. By pressing the button next to the tenth port so that it is in the OUT position, the port 10X will become an MDI-II Uplink port for connecting the internet server to another hub. BNC – LAN The DP-692 provides a BNC port for cascading with other hubs without sacrificing any RJ-45 ports.
Internet Server User’s Guide Diagnostic LED Descriptions The internet server has an LED array for indicating current port and transmission status and is shown below. DP-692 Front Panel LEDs • Power ◊ ON: “power good”. ◊ OFF: “power bad.” Check to see if the AC power adapter is properly connected, or if the correct AC power adapter is being used. • Collision ◊ Blinking: Packet collision is occurring. Packet collisions are not an abnormal situation.
Internet Server User’s Guide ◊ ON: Data link between UTP port and host computer’s or uplinked hub’s UTP port is successful. ◊ OFF: No data link or cable disconnected. Check for bad cable or loose connectors. For uplinked hubs, check to see if UTP cable contains crossed-over wires. Also check for a “power good” condition at both ends of the connection. If you suspect that the hub port is damaged, contact your authorized dealer for service. ◊ Blinking: Packet reception is occurring. • Rx (for BNC port).
Internet Server User’s Guide • COM1 / COM2 ◊ ON: Each COM port LED provides an indication of the operating status of the corresponding WAN port. When a WAN port is transmitting data, the related COM port indicator will light. ◊ OFF: No data is being transmitted. • Link/Rx (at far right) ◊ ON: The (internal) link between the Internet server’s LAN and Hub circuits is OK. ◊ OFF: The link between the Internet server’s LAN and Hub circuits is not working.
Internet Server User’s Guide Normal LED Flash Pattern Immediately after power-up, both COM LEDs should display steady green for several seconds. Then both COM LEDs should flash simultaneously three times. This sequence of flashes should be followed by first COM1 flashing once and then COM2 flashing once, repeated three times in succession.
Internet Server User’s Guide through cable into the 10X LAN port on the internet server, and the other end into a normal (non-Uplink) port on a hub or switch (as shown below). Both devices can be receiving power when making this connection. Please note that when making this connection the button next to the 10X port should be in the Uplink (OUT) position.
Internet Server User’s Guide Connecting Through Thin Coaxial Cable The BNC port on the DP-692 can be used to uplink hubs together. Actually, you can cascade the DP-692 with any other IEEE 802.3 compliant 10BASE-T Ethernet hubs equipped with BNC ports. You may attach up to thirty nodes to a thin coaxial segment. In this sense, it is possible to cascade a maximum of thirty hubs together through the thin coaxial cable. Be sure to leave a minimum of 0.5 meter (2 feet) of cable between two BNC ports.
Internet Server User’s Guide (NIC) installed in a PC as shown below. Please note that the example shown below uses a BNC connection to a network backbone. You may also use the Uplink port (port 10X) connection described above but you must ensure that no signal loops are formed. Connecting to the Internet The internet server must be connected to the internet (this is also known as a Wide Area Network or ‘WAN’ connection) using a COM serial port.
Internet Server User’s Guide Modem Connection Connecting Power Power is supplied to the internet server through an AC power adapter. Connecting Power Since the internet server does not include a power switch, plugging its power adapter into a power outlet will immediately power it on.
Internet Server User’s Guide After the internet server is connected to the LAN and powered on, you can use the included IS Admin software to assign an IP address to the device. Once the internet server has a valid IP address, you may set it up for normal operations (i.e. connecting to the internet) from any network station through Telnet or a web browser.
Internet Server User’s Guide 3 S YSTEM S ETUP The internet server has some settings that need to be properly configured before it can be used. This chapter describes how to change the default IP address settings and then how to use Telnet or a web browser to further configure the internet server. A description of the minimum settings changes required for operation is also provided. A full listing of all settings in the internet server is provided in Chapter 4.
Internet Server User’s Guide Setting IP Addresses The IP address settings, which include the IP address, subnet mask and gateway IP address are the first and most important settings that need to be configured. The internet server comes with a default Local LAN IP address and subnet mask assigned. If you do not have a preexisting IP network and are setting one up now, using the factory default IP address settings can greatly ease the setup process.
Internet Server User’s Guide Default Addressing Example Host IP Address Subnet Mask Gateway IP Internet Server 192.168.100.1 255.255.255.0 Computer #1 192.168.100.2 255.255.255.0 192.168.100.1 Computer #2 192.168.100.3 255.255.255.0 192.168.100.1 Computer #3 192.168.100.4 255.255.255.0 192.168.100.1 Please note that when using the default IP address as in the above example, the first three numbers in the IP address must always be the same with only the fourth number changing.
Internet Server User’s Guide Changing the IP Address of the Internet Server If your LAN is already setup for IP networking and you wish to change the IP address of the internet server to operate within your existing IP network, simply: 1. 2. 3. 4. 5. 6. 7. 8. 9. Physically connect the internet server to your LAN and power it on. Configure one computer on your network to have the IP address of 192.168.100.2 (or any unique IP address in the 192.168.100.XXX network) and a subnet mask of 255.255.255.0.
Internet Server User’s Guide Press the key to access the configuration program. There is no default password. Once you have access, use the menu item numbers to navigate the menus and change settings. All settings are described later in this manual. Note: System Setup Make sure to save the configuration after modifying device settings. The Save Configuration function immediately ends the Telnet session and restarts the internet server in the new configuration.
Internet Server User’s Guide Using a Browser to Configure the Server Once your PC is configured with an IP address on the same subnet as the internet server, start your browser program and enter the prefix “http://” followed by the IP address assigned to the server, in the address window. You should immediately see the internet server web browser interface menu as shown below. Note that the internet server IP address can be bookmarked for future access so that it doesn’t need to be entered each time.
Internet Server User’s Guide The browser interface uses frames, so it is best if you use a frames-capable browser program. Also, we advise you to temporarily suspend the use of proxies – if you are using them – while accessing the internet server as proxy settings may interfere with browser access to local devices. If you use a non-frames browser, when you receive the initial internet server screen, you should see the main navigation menu rather than the navigation menu and the system status screen.
Internet Server User’s Guide view, set or modify. Some settings can be entered manually while others must be selected from pull-down menus. Minimum Configuration Regardless of how you intend to use the internet server, you will need to consider and set some basic system settings. This section is concerned with describing only those settings that are critical to the proper functioning of the internet server.
Internet Server User’s Guide Description: A Domain Name Service (DNS) server address is used to translate URLs into their corresponding IP addresses. ISP Account -> Phone Number In order for the internet server to control the modem to dial the phone, you must enter the dial-up phone number for your ISP. If you need to dial an area code in order to call the number, it must be included in this variable.
Internet Server User’s Guide Note: If the ISP phone line is busy, the internet server will automatically redial. Three successive redial attempts will be made. ISP Account -> User ID Just as the internet server needs to know what phone number to dial to access your ISP, it also needs to know what username to login under. This variable is the username the ISP has assigned to you or your company. Options: Needed for dial-up connections. The ISP assigned user ID exactly as provided (i.e.
Internet Server User’s Guide where necessary, underscores and other punctuation included). The maximum length is 32 characters. Default Value: (none) Must Be User Modified? Yes. Description: This variable is the user password that will be provided to the ISP once the modem connection is established and the username has been accepted. Notes: It may not be possible with some ISPs to use this variable to allow the internet server to automatically login.
Internet Server User’s Guide Example: If your ISP asks you to input a user ID, password, and to choose from a list of available communications protocols each time you dial-up, your login script would look like something like this: No. Prompt Keyin 1 Username: Nick Didovic 2 Password: Example 3 Protocol --> 2 With each prompt being the text of the prompt provided by the ISP, and each keyin being the exact data you would enter.
Internet Server User’s Guide Operation To access the internet, do the following at each station (computer) that will use the internet server for internet access: 1. Make sure that TCP/IP settings are configured properly. IP parameters that must be set: • IP Address – must be a unique IP address chosen from the three reserved IP ranges set aside for local network only use. If using DHCP, make sure that each computer is set to 0.0.0.0 or to ‘Obtain an IP Address automatically’.
Internet Server User’s Guide 4 C ONFIGURATION S ETTINGS This chapter provides information about all of the configuration settings available on the internet server. Information about the range of values, default settings, and purpose of each setting is given. Items are listed in the same order as the menu listings presented by the internet server Telnet console program. Note that some settings have been defined in further detailed in Chapter 3.
Internet Server User’s Guide ♦ Return to Menu – Takes you up one menu level (generally to the menu immediately preceding the current menu). System Configuration Server Name Options: A fifteen-character string of letters and numbers. Default Value: IS-xxxxxx (where “xxxxxx” is the last six digits of the device’s MAC address). Description: The server name is used to identify the internet server on network management lists of active devices.
Internet Server User’s Guide cal network devices must start with 192.168.100 and have a final number between 2 and 255. Local LAN -> Subnet Mask This variable defines the subnet level the internet server will share with other devices on the network. Options: level. Any subnet address which identifies a subnet Default Value: 255.255.255.0 Must Be User Modified? No. Description: The subnet mask is used to identify subgroups on a LAN.
Internet Server User’s Guide Description: A Domain Name Service (DNS) server address is used to translate URLs into their corresponding IP addresses. Maximum Idle Time This variable allows you to set an idle time after which the internet server will automatically disconnect the WAN connection. Setting an idle time lets you keep from staying logged-in to your ISP when no one is using the internet. Options: A time duration from 1 to 65535 minutes. Default Value: 30 minutes Must Be User Modified? No.
Internet Server User’s Guide Description: This option only needs to be changed if the internet server isn’t going to be used to connect directly to an ISP. Enabling LAN-to-LAN mode automatically disables the LAN-to-WAN Internet server and Server Address Mapping functions. LAN-to-LAN mode should be used when you need to expand your LAN but have limited IP addresses available and internet access is provided via a router.
Internet Server User’s Guide Default Value: Dialup Description: The WAN port must be configured for use as either a dial-up connection or a leased-line connection. Baud Rate Options: 4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800 bps. Default Value: 115200 bps Description: The setting of this variable sets the maximum bits per second data transmission rate on the line. Generally, the rate should be set equal to or greater than the maximum possible transmission rate of the device (e.g.
Internet Server User’s Guide ISP Account -> User ID Options: For dial-up connections, the ISP assigned user ID name exactly as provided (i.e., all letters capitalized where necessary, underscores and other punctuation included). The maximum length is 64 characters. Default Value: (none) Description: This variable is the user ID that will be provided to the ISP once the modem connection is established.
Internet Server User’s Guide Modem AT Commands Options (sub- settings): ♦ Init. String: (default) ♦ Dial Prefix String: (default) ♦ Hang-up String: <~~~+++~~~ATH0> (default) Description: Modem AT commands are used to configure and operate the modem when it is necessary to control settings such as the speaker volume, line modulation, or handshaking protocol. Note: See your modem user’s guide for information about initialization string settings and other modem commands.
Internet Server User’s Guide Login Script Options: For each line item, a prompt string and a keyin string must be provided. The prompt string is the text displayed by the ISP requesting that something be entered. The keyin string is what should be entered. Prompt strings can be up to 25 characters long including punctuation. Keyin strings can be up to 20 characters long including punctuation (a maximum of 8 separate line entries).
Internet Server User’s Guide DHCP Server Configuration The Dynamic Host Configuration Protocol (DHCP) allows servers and devices like the internet server to dynamically assign IP addresses to network devices. Dynamic IP assignment alleviates the need for the network administrator to maintain and monitor IP address assignments and simplifies IP use because IP address are automatically and dynamically assigned when a station powerson. DHCP is factory defaulted to ON.
Internet Server User’s Guide IP Address Range -> Start The range of IP addresses available to the internet server for DHCP allocation is set using two settings. This is the first. Options: Any IP address within the three reserved IP ranges. The IP chosen must correlate with the End of the range. Default Value: 192.168.100.101 Must Be User Modified? No. Description: This variable indicates the beginning of the range of IP addresses available for DHCP use in assigning IPs.
Internet Server User’s Guide Default Value: 1440 (24 hours) Description: Dynamically assigned addresses can be periodically “refreshed” by a DHCP server. The IP Lease Time variable allows you to set that time limit. If a time is entered in this variable, each dynamically assigned address will be recycled at the end of the lease time. IP Reserve Table Options: Local IP Address, MAC Address (a maximum of 16 separate line entries).
Internet Server User’s Guide context are “virtual” because they don’t have their own public domain IP addresses in the typical internet fashion. Rather, their local IP address, with an access port number, is listed in a table inside the internet server. The port number provides the internet server with the reference to correctly route data requests. Note that in LAN-to-LAN mode, this function is disabled and no LAN devices can be accessed from the internet. ♦ No. Item number used for entry editing.
Internet Server User’s Guide Note: The port numbers in the above example are those commonly used for Telnet, FTP, and web servers respectively, but the port number should correspond to that assigned when the server is setup. Advanced Control Configuration Manager Server IP Address This setting is the IP address of the computer using the IS Manager Server software included with the device. The default IP address is 0.0.0.0.
Internet Server User’s Guide A table showing all the hours in all the days of the week. Choose Add to add a period of time to the table during which the internet server can dial out. ♦ Holiday Table The holiday table is used to create exceptions to the schedule table. The holiday table lists all 12 months. Choose Add to add a date to the holiday table. Any dates designated in the holiday table will keep the internet server from dialing out on that day.
Internet Server User’s Guide ule table. If a request is received to access the internet outside of the time limits defined in the schedule table, the internet server will not dial out. Traffic Control The traffic control feature allows you to define how the internet server manages traffic between the two WAN ports, assuming that both have connections to the internet. The default traffic control setting is by User Connection with 6 users per port.
Internet Server User’s Guide WAN 1, totaling 6 people using this port. The 7th user accessing the internet will cause WAN 2 to dial up as long as the other 6 users are still using WAN 1. If one of the previous users has stopped using the internet, thereby freeing up space on WAN 1, the 7th user will be placed on WAN 1. However, if all 6 users are still on WAN 1, the 7th user will be placed on WAN 2. The 8th to 12th users will all be placed on WAN 2 as well.
Internet Server User’s Guide for the internet. All traffic will be balanced between the two WAN ports offering the highest possible bandwidth and the fastest internet access to all users. Routing Table The static routing table allows the internet server to coexist on the same network with a router. This implementation depends on whether the router has its own WAN access to the internet. If the router does not have a connection to the internet, then you do not need to create a new IP network or IP subnet.
Internet Server User’s Guide server’s routing table. When doing this, the IP address of the static route will be the preexisting IP address and the gateway will be the LAN port of the router. Note: If you are creating a second IP network, do not allow the internet server to use DHCP if the router is also using DHCP, unless the router is supplying IP addresses on only one port and the internet server is not connected to that port.
Internet Server User’s Guide Displays all configuration data for the device (addresses, ports, links, etc.). Configuration data is a readout of the settings that are user-defined as described in this chapter. ♦ DHCP Server Status Displays a table of DHCP servers with the following information: IP Address, MAC Address, and Lease Time. ♦ User Connection Status Displays a table of current user connections with the following data: Source IP, Destination IP, Protocol, Path, and Idle.
