Introduction to the Router

This chapter describes the Router and it features and includes an introduction to ADSL technology. Diagrams are provided detailing the hardware and LED indicators. A list of package contents is presented at the end of the chapter.

Router Description and Operation

The DSL-500 ADSL Router is designed to provide a simple, cost-effective and secure ADSL Internet connection for your small- to medium-sized private network. The DSL-500 combines the benefits of high-speed ADSL connection technology and TCP/IP routing with a conventional Ethernet interface in one compact and convenient package. ADSL connection technology enables many interactive multi-media applications such as video conferencing and collaborative computing.

The Router is easy to install and use. The DSL-500 connects to an Ethernet LAN via a standard Ethernet 10BASE-T interface using RJ-45 connectors. The ADSL connection is made using ordinary twisted-pair telephone line with standard RJ-11 connectors. This arrangement means that several PCs can be networked and connected to the Internet using a single WAN interface and IP address.

The Router supports transparent bridging and can be used for IP packet routing over the Internet. Cost saving features of the Router such as NAT (Network Address Translator) and DHCP (Dynamic Host Configuration Protocol) improve administration efficiency and improve security. The advanced security enhancements, packet filtering and port redirection, can help protect your network from potentially devastating intrusions by malicious agents from outside your network.

ADSL Technology

Asymmetric Digital Subscriber Line (ADSL) is an access technology that utilizes ordinary copper telephone lines to enable broadband high-speed digital data transmission and interactive multimedia applications for business and residential customers. The use of existing copper telephone lines forgoes the need for upgrading lines or adding expensive new cable.

ADSL devices use digital coding techniques that greatly increase the potential capacity of phone lines without interfering with regular telephone services. For the ADSL user, this means much faster data communications and the potential for interactive video capabilities. ADSL devices make it possible to enjoy benefits such as high-speed Internet access, telecommuting (remote LAN access), collaborative computing, distance learning, movies on demand and multi-player

DSL-500 ADSL Router User’s Guide

video gaming, without experiencing any loss of quality or disruption of voice/fax telephone capabilities.

ADSL provides a dedicated service over a single telephone line operating at speeds of up to 8 Mbps downstream (to the user) and up to 640 Kbps upstream depending on local telephone line conditions. These conditions are ideal for many user applications. A secure point-to-point connection is established between the user and the central office of the local telephone service provider. The user is always connected thus eliminating dial-up time and simplifying connectivity issues.

Product Features

The DSL-500 ADSL Router utilizes the latest ADSL enhancements and router technologies to provide a robust Internet gateway suitable for most small to medium sized offices.

PPP (Point-to-Point Protocol) Security

The DSL-500 ADSL Router supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake Authentication Protocol) for PPP connections.

DHCP Support (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) automatically and dynamically assigns al LAN IP settings to each host on your network. This eliminates the need to reconfigure every host whenever changes in network topology occur.

Network Address Translation (NAT)

For small office environments, the DSL-500 allows multiple users on the LAN to access the Internet concurrently through a single Internet account. This provides Internet access to everyone in the office for the price of a single user.

NAT improves network security in effect by hiding the private network behind one global and visible IP address. NAT address mapping can also be used to link two IP domains via a LAN-to-LAN connection.

TCP/IP (Transfer Control Protocol/Internet Protocol)

The DSL-500 supports TCP/IP protocol, the language used for the Internet. It is compatible with access servers manufactured by major vendors.

RIP-1/RIP-2

The DSL-500 supports both RIP-1 and RIP-2 exchanges with other routers. Using both versions lets the Router to communicate with all RIP enabled devices.

DSL-500 ADSL Router User’s Guide

Static Routing

This allows you to select a data path to a particular network destination that will remain in the routing table and never “age out”. If you wish to define a specific route that will always be used for data traffic from your LAN to a specific destination within your LAN (for example to another router or a server) or outside your network (to a ISP defined default gateway for instance).

Default Routing

This allows you to choose a default path for incoming data packets for which the destination address is unknown. This is particularly useful when if the Router functions as the sole connection to the Internet.

ATM (Asynchronous Transfer Mode)

The DSL-500 supports (RFC1577) and Virtual Circuit Connections (VCCs).

PPP over ATM

Bridged Ethernet over ATM

(RFC 2364). The Router can support up to eight

(RFC1483),

IP over ATM

Precise ATM Traffic Shaping

Traffic shaping is a method of controlling the flow rate of ATM data cells. This function helps to establish the Quality of Service for ATM data transfer.

G.hs (Auto-handshake)

This allows the Router to automatically choose either the G.lite or G.dmt ADSL connection standards.

High Performance

Very high rates of data transfer are possible with the Router. Up to 8 Mbps downstream bit rate using the G.dmt.

Full Network Management

The DSL-500 incorporates SNMP (Simple Network Management Protocol) support for web-based management and text-based network management via an RS-232 or

Telnet

connection.

Telnet Connection

The Telnet enables a network manager to access the Router’s management software remotely.

Easy Installation

The DSL-500 uses a web-based graphical user interface program for convenient management access and easy set up. Any common web browser software can be used to manage the Router.

Prepare for Installation

For the smoothest possible installation, assemble all the equipment and information needed to set up the Router and establish the initial ADSL connection before you begin. Everything needed for the installation is listed and discussed in this chapter.

Microfilters and Splitters

Most ADSL clients will be required to install a simple device that prevents the ADSL line from interfering with regular telephone services. These devices are commonly referred to as microfilters or sometimes called (inaccurately) line splitters. They are easy to install and use standard telephone connectors and cable.

Some ADSL service providers will send a telecommunications technician to modify the telephone line, usually at the point where the phone line enters the building. If a technician has divided or split your telephone line into two separate lines - one for regular telephone service and the other for ADSL – then you do not need to use any type of filter device. Follow the instructions given to you by your ADSL service provider about where and how you should connect the Modem to the ADSL line.

DSL-500 ADSL Router User’s Guide

Microfilters

Unless you are instructed to use a “line splitter” (see below), it will be necessary to install a microfilter (low pass filter) device for each telephone or telephone device (answering machines, Faxes etc.) that share the line with the ADSL service. Microfilters are easy-to-install, in-line devices, which attach to the telephone cable between the telephone and wall jack. Microfilters that install behind the wall plate are also available. A typical in-line microfilter installation is shown in the diagram below.

Microfilter Installation

Note:

Do not install the microfilter between the Modem and the telephone jack. Microfilters are only intended for use with regular telephones, Fax machines and other regular telephone devices.

If you are instructed to use a “line splitter”, you must install the device between the Modem and the phone jack. Use standard telephone cable with standard RJ11 connectors. The splitter has three RJ-11 ports used to connect to the wall jack, the Modem and if desired, a telephone or telephone device. The connection ports are typically labeled as follows:

Line

- This port connects to the wall jack.

ADSL

Phone

– This port connects to the Modem.

– This port connects to a telephone or other telephone device.

The diagram below illustrates the proper use of the splitter.

Additional Requirements

You will need a PC (referred to in this guide as the Manager PC) to set up and use the Router. In addition, it will be necessary to configure the device using information provided by your ADSL service provider. This information is used to establish the parameters of the ADSL connection and identify the Router on the WAN. The requirements for the PCs on your LAN are summarized below.

PC WORKSTATION REQUIREMENTS

You can use the Router with PCs that meet the conditions discussed here.

Operating System

The web-based management software can be used on PCs running one of the following operating systems:

CONNECTION METHOD

It is necessary to know the connection method used for the ADSL connection. The connection method is also known as the ADSL Protocol, Encapsulation Protocol or Encapsulation Method. These protocols are defined by “RFCs” which are internationally recognized standards for networking protocols. You will be required to configure the Router to use the correct method. PPP connections require account information to be entered and stored in the device. Bridged Ethernet connections require that the IP settings be set manually.

The Router supports three connection methods:

♦

PPP over Ethernet (RFC 2516) used by default

♦

PPP over ATM (RFC 2364)

♦

Ethernet over ATM (RFC 1483)

BRIDGED ETHERNET CONNECTIONS (RFC 1483)

For Bridged Ethernet connections it will be necessary to give the Router a global IP address and default gateway.

Global IP Address

If the connection method used is Ethernet over ATM (RFC 1483), a unique global IP address will be needed for the Router. The assigned global IP address must be entered When using the default connection method, PPP over Ethernet (RFC 2516), a global IP address will be assigned automatically during the connection process.

only if

the connection method used is Ethernet over ATM (RFC 1483).

Default Gateway IP Address

Some network service providers require that a default gateway router be used by the Router to connect to their network backbone. If this is the case, the IP address of the default gateway (router) must be entered during the configuration of the device.

Hardware Installation

This chapter discusses the various connections you will need to make in order to use the Router.

When selecting the location for the Router, allow room to access the connections on the rear panel. You will want to place the Router so that you will be able to see the LED indicators on the front panel. Also allow some space above the Router for ventilation to avoid problems with overheating.

It may be convenient for you locate the Router near the PC you intend to use for initial configuration of the Router. For initial configuration of the device you may need convenient access to the RS-232 serial port on the rear panel. The RS-232 serial port is intended for use with text-based console management software for the initial configuration and for out-of-band management of the Router. Whether it is necessary to use an RS-232 console manager for first time set up depends on how you allocate IP addresses on your network. Read Chapter 4,

to help you decide how best to use the Router on your network.

First Time Set

Connect the Power

Insert the AC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a nearby power source. You should see the Power LED indicator light up and remain lit.

Connect ADSL Line

Use the twisted-pair ADSL cable (standard telephone cable) included with the Router to connect it to your telephone line. Simply plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the wall jack. The ADSL connection is the WAN interface. It links the Router to the network service provider’s backbone infrastructure. This is the Router’s access point to the Internet.

The Router must undergo a negotiation process to establish the terms of the ADSL connection. During this negotiation the Status LED will light a steady green, after which it will blink. If the ADSL line is disconnected, it will repeat this process.

Connect Ethernet LAN to Router

The Router may be connected to any 10BASE-T Ethernet LAN. Connection to an Ethernet concentrating device such as a switch or hub should use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a

DSL-500 ADSL Router User’s Guide

straight-through (MDI-X) connection. Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. Use a normal crossed cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch. When connecting the Router directly to a PC or server (MDI-II) use a straight-through cable. A valid connection will be indicated by a steady green Ethernet Link LED indicator.

The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the Ethernet LAN to the Router does not exceed 100 meters.

The diagram below illustrates a typical Ethernet LAN to Router connection.

DSL-500 ADSL Router User’s Guide

Connect Server or PC to Router

The Router may be connected directly to a server or PC using the RJ-45 Ethernet port. The diagram below illustrates a PC/Server to Router connection with the Router being employed as a firewall.

PC/Server to Router Connection

DSL-500 ADSL Router User’s Guide

First Time Set Up

It will be convenient for most users to establish an initial ADSL connection for one PC equipped with an Ethernet NIC (Network Interface Card). It is recommended that you install and configure the Router using one non-networked computer. This allows you to verify that the ADSL service is functioning and that you are able to communicate with the device. Once the initial ADSL connection is established, you can proceed to build an Ethernet LAN around the device or incorporate it into an existing LAN. For convenience, the PC used to configure the Router is henceforth referred to as the manager PC.

To further simplify things it is recommended that you use the Router’s web-based management software for initial configuration. To communicate with the Router, the manager PC must be connected to it via an Ethernet connection and have a web browser installed. Furthermore, the manager PC must reside within the same subnet as the Router. This can be done easily using the DHCP function of the Router. The Router will act as a DHCP server by default. You can configure the manager PC to obtain its IP settings from the Router by following the procedure in the next section.

You should start by configuring the manager PC to obtain IP settings from the Router. Next disconnect the manager PC from the network and connect it directly to the Router with a straight-through Ethernet cable.

If you do not wish to change the existing IP settings of the manager PC, you can change the IP address of the Router. For instructions for changing the Router’s IP address read Chapter 6,

LAN Setup

Configure the WAN Connection

Now that you have accessed the web-based manager, you must configure the Router for the ADSL connection (VPI/VCI pair) and provide other information to establish the WAN connection. The other information provided depends on the type of WAN connection you have. For PPPoE and PPPoA connections, you will need to provide a User Name and Password used for authentication purposes. For “Bridged Ethernet” (RFC 1483) connections a static IP address must be used. It is necessary to supply IP settings for the WAN connection and other information discussed in Chapter 2, methods available to the Router are discussed in this chapter, beginning with PPPoE connections. PPPoE is the most commonly used protocol to provide ADSL connection and is the default method used by the Router. For a more detailed discussion of the various menu items in the connection configuration windows, see Chapter 5,

Router Functions

The DHCP and NAT functions of the Router allows the network manager to more easily manage IP addresses and subnets, and enhance network security by presenting only one global IP address to the Internet. This section discusses how to use these conventional routing functions.

DHCP

The Dynamic Host Configuration Protocol (DHCP) allows the Router to assign IP addresses to all properly configured hosts on the network. 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 assigned when a station powers-on. Click on the DHCP Configuration button to see the DHCP menu.

IMPORTANT

stations on the network must be either manually configured to 0.0.0.0 or, select the “Obtain an IP address automatically” option under the TCP/IP Properties tab in the Network menu. See the Configure the Manager PC section at the beginning of Chapter 4 for more explicit instructions.

: If you use DHCP to set your local IP addresses, the IP settings of all

DHCP Configuration Window

In the DHCP Configuration window you define the following:

Start IP Address

This is the base (starting) address for the IP pool of unassigned IP addresses.

End IP Address

This is the last address of the contiguous IP address range to be used by the Router for DHCP function.

DSL-500 ADSL Router User’s Guide

Netmask

This mask informs the client, how the destination IP address is to be divided into network, subnet, and host parts. The netmask has ones in the bit positions in the 32-bit address which are to be used for the network and subnet parts, and zeros for the host part.

Default Gateway

This specifies the Gateway IP Address that will be assigned to and used by the DHCP clients.

Leased Time

This specifies the amount of time (in seconds) a client can lease an IP address, from the dynamically allocated IP pool. A value of 4294967295 means the lease is permanent.

DNS Server IP

Domain Name Service (DNS) servers are used on the Internet to match the Uniform Resource Locator (URL) for a website to its Internet IP address. For example, the URL: www.cnn.com, is a pseudonym for the IP address:

207.25.71.25. DNS entries allow users to access resources using URLs instead of IP addresses.

You may enter any Internet DNS server IP address available through the WAN connection. This address should be provided by your network service provider. (Note that without a DNS server IP, internet sites will only be available using IP addresses and will not be available using URLs.)

NAT Configuration

Network Address Translation (NAT) is a routing protocol that allows your network to become a Internet. It does this by changing the IP address of packets from a address usable on the Internet to a network (but not on the Internet) and vice-versa. The Router allows up to 128 host IP addresses.

NAT has two major benefits. First, NAT allows many users to access the Internet using a single global IP address. This can greatly reduce the costs associated with Internet access and also helps alleviate the current shortage of Internet IP addresses. Secondly, the NAT process creates an added degree of security by hiding your private network behind one IP address. The NAT function will normally only allow incoming packets that are generated in response to a request from a host within the LAN.

Port Redirection to allow appropriate use of your servers by outside users. See the section on Port Redirection for more information.

For the purposes of network administration, NAT is almost indispensable. Hosts and servers on the internal network can be moved easily. Using NAT together with DHCP can greatly reduce the workload of a network manager while allowing tremendous flexibility.

Security Features

Network security is an unfortunate necessity for any network connected to the Internet. Protection of sensitive information and proprietary assets on your private network should be designed into the network infrastructure from the beginning. If you are not already, it is recommended that you become familiar with network security issues and the strategies available to help reduce risks from outside as well as from within your LAN. The Router provides features that can enhance your network security and should be used in concert with other security provisions, such as virus scanning software for all workstations, the use of proxy servers and stateful inspection methods.

Advanced Filtering and Firewall

One of the most important elements of any network security implementation is the firewall. Packet filtering is a basic firewall security measure that should be used on any network that is exposed to security risk. A packet filter system examines data packets and scrutinizes them for the purpose of controlling network access. Filtering rules determine whether or not to allow access through the Router from either side of the gateway. The rules are created and controlled by the network administrator and can be precisely defined. These rules are used to block access to the network from the outside, or deny access to the WAN from within the network. The Router uses filtering rules to examine data packet headers for specific information. Packets passing through the Router that do not meet the criteria specified by the rule set are dropped.

In order to improve network security without severely limiting network efficiency, it is important to carefully plan the sets of access rules. Effective implementation of packet filtering requires detailed knowledge of network services and communication protocols. An overly complicated filtering scheme can adversely effect routing performance, while an inadequate set of rules may needlessly compromise security.

Packet filtering can be used in conjunction with NAT, port redirection and proxy servers to help provide basic firewall protection. However, these measures do not address many security issues and should be used as only one part of an overall network security strategy. It is important to remember that IP packet filtering examines only the packet header and is not concerned with application information. Therefore, packet filtering does not protect against higher-level security threats that may operate at the application or other level.

Filtering rules can be precisely defined based upon source and destination IP address, as well as port and protocol information. Up to twelve filter sets can be used; each set contains up to seven filtering rules subsets.

: the port number does not equal to the Start Port if there is no End Port specified; if an End Port number is specified, this defines a range of ports not to filter. The range is defined as the port numbers between the Start Port and End Port, including the Start and End Port numbers.

Port Redirection

Port Redirection Window

The Port Redirection feature of the Router is used in conjunction with NAT to improve security and efficiency. Port redirection can be used to direct potentially hazardous packets to a proxy server outside your firewall. For example, it is common practice to direct HTTP packets to a designated HTTP server in the DMZ. Other common applications might include directing incoming SMTP packets to an Email server for data scrutiny and improved network efficiency. Click the

LAN Setup

The Router allows many possibilities for network layout. This gives the network administrator much flexibility to decide how best to use it. One of the most important decisions for the network administrator involves IP addressing on the LAN. The easiest choice in most cases is to let the Router take care of it for you using DHCP, which is done by default. This chapter discusses the various alternatives for IP address assignment using the Router.

Assigning Network IP Addresses

The IP address settings, which include the IP address, subnet mask and gateway IP address are the first and most important internal network settings that need to be configured. The Router is assigned a default LAN IP address and subnet mask. 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. If you already have a preexisting IP network, you can adjust the IP settings for the Router to fit within your existing scheme.

Using the Default IP Address

The Router comes with a preset default IP address setting of 192.168.0.1 for the LAN port. There are two ways to use this default IP address, you can manually assign an IP address and subnet mask for each PC on the LAN or you can instruct the Router to automatically assign them using DHCP. The simplest method is to use DHCP. The DHCP function is active by default.

Manual IP Address Assignment

You can manually set the IP address, subnet mask and default gateway on each computer by performing the following steps for each PC on the network:

1. In Windows 95/98, click on the

Control Panel

2. In the window that opens, double-click on the

192.168.0.4 255.255.255.0 192.168.0.1

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 (for a Class C network). This is because the first three numbers define the network IP address (all machines must belong to the same IP network), while the last number denotes the host IP address (each computer must have a unique address to distinguish it on the network). Also note that the subnet mask is the same for all machines and the default gateway address is the LAN IP address of the Router.

It is a good idea to make a note of each device’s IP address for reference during troubleshooting or when adding new stations or devices.

Using DHCP

The second way to use the default settings is to allow the Router to automatically assign IP addresses to your computers using DHCP. To do this, simply make sure your computers’ IP addresses are set to 0.0.0.0 (under Windows, choose the option Obtain an IP address automatically in the TCP/IP network component described above). When the computers are restarted, their IP settings will automatically be assigned by the Router. The Router is set by default to use DHCP. See the discussion in Chapter 5 for information on how to use configure the Router for DHCP.

Changing the IP Address of the Router

If you choose to change the IP address of the Router you will need to access the device directly via the RS-232 connection using a terminal emulation interface (such as Microsoft HyperTerminal used in the sample screen captures). Your terminal parameters will need to be set to:

VT-100/ANSI compatible Terminal keys enabled 9,600 baud 8 data bits No parity One stop bit

DSL-500 ADSL Router User’s Guide

Connect a standard RS-232 (DB-9 to DB-9) cable to the Router’s RS-232 port on the rear panel, connect the other end to a PC with a terminal emulation program already installed. Power on the Router and launch the emulation program. The terminal emulator will display system information while the unit undergoes selftesting. When

192.168.0.1>

appears on the screen the unit has completed its self-test. In this mode, the default IP address 192.168.0.1 and an angle bracket (“greater than”) will appear each time the Enter key is depressed.

HyperTerminal Interface with new IP address

You must save the new IP address by typing the command series

and pressing Enter. This will save the new IP address for the Router and store it in the device’s flash memory. You may now disconnect the terminal emulator and access the device using the web-based management interface for configuration. For more thorough instructions on using the out-of-band console manager, see Chapter 7.

DSL-500 ADSL Router User’s Guide

Using the Console Manager

Settings for the Router can be configured via the RS-232 console port connection using terminal emulation software such as Microsoft HyperTerminal included with Microsoft’s operating systems. This chapter lists and describes a few of the most essential command sets that might be used by the typical user. This chapter is not intended to be a complete list of the commands available.

General Use

To use a terminal emulation interface with the device, the terminal parameters will need to be set to:

VT-100/ANSI compatible Terminal keys enabled 9,600 baud 8 data bits No parity One stop bit

With the correct parameters set and the RS-232 connection established you should be able to use the keyboard to communicate with the device. If the Router is powered on when the terminal interface appears, depress the Enter key to bring up the initial prompt. This will be the IP address of the device. For information about changing the IP address, please read the section in Chapter 6.

If at any time you want to view a list of commands available in the particular mode you are currently operating, type

a list of the commands available in the current mode. For example, type help after the initial IP address prompt and you will see a menu similar to this:

IP Concepts

This appendix describes some basic IP concepts, the TCP/IP addressing scheme and show how to assign IP Addresses.

When setting up the Router, you must make sure it has a valid IP address. Even if you will not use the WAN port (ADSL port), you should, at the very least, make sure the Ethernet LAN port is assigned a valid IP address. This is required for telnet, in-band SNMP management, and related functions such as “trap” handling and TFTP firmware download.

IP Addresses

The Internet Protocol (IP) was designed for routing data between network sites all over the world, and was later adapted for routing data between networks within any site (often referred to as “subnetworks” or “subnets”). IP includes a system by which a unique number can be assigned to each of the millions of networks and each of the computers on those networks. Such a number is called an IP address.

To make IP addresses easy to understand, the originators of IP adopted a system of representation called “dotted decimal” or “dotted quad” notation. Below are examples of IP addresses written in this format:

201.202.203.204 189.21.241.56 125.87.0.1

Each of the four values in an IP address is the ordinary decimal (base 10) representation of a value that a computer can handle using eight “bits” (binary digits — 1s and 0s). The dots are simply convenient visual separators.

Zeros are often used as placeholders in dotted decimal notation; 189.21.241.56 can therefore also appear as 189.021.241.056.

IP networks are divided into three classes on the basis of size. A full IP address contains a network portion and a “host” (device) portion. The network and host portions of the address are different lengths for different classes of networks, as shown in the table below.

DSL-500 ADSL Router User’s Guide

Networks attached to the Internet are assigned class types that determine the maximum number of possible hosts per network. The previous figure illustrates how the net and host portions of the IP address differ among the three classes. Class A is assigned to networks that have more than 65,535 hosts; Class B is for networks that have 256 to 65534 hosts; Class C is for networks with less than 256 hosts.

223.255.254(.0)

Note:

All network addresses outside of these ranges (Class D and E) are either reserved

or set aside for experimental networks or multicasting.

When an IP address's host portion contains only zero(s), the address identifies a network and not a host. No physical device may be given such an address.

The network portion must start with a value from 1 to 126 or from 128 to 223. Any other value(s) in the network portion may be from 0 to 255, except that in class B the network addresses 128.0.0.0 and 191.255.0.0 are reserved, and in class C the network addresses 192.0.0.0 and 223.255.255.0 are reserved.

The value(s) in the host portion of a physical device's IP address can be in the range of 0 through 255 as long as this portion is not all-0 or all-255. Values outside the range of 0 to 255 can never appear in an IP address (0 to 255 is the full range of integer values that can be expressed with eight bits).

The network portion must be the same for all the IP devices on a discrete physical network (a single Ethernet LAN, for example, or a WAN link). The host portion must be different for each IP device — or, to be more precise, each IPcapable port or interface — connected directly to that network.

DSL-500 ADSL Router User’s Guide

The network portion of an IP address will be referred to in this manual as a

network number

; the host portion will be referred to as a

host number

To connect to the Internet or to any private IP network that uses an Internetassigned network number, you must obtain a registered IP network number from an Internet-authorized network information center. In many countries you must apply through a government agency, however they can usually be obtained from your Internet Service Provider (ISP).

If your organization's networks are, and will always remain, a closed system with no connection to the Internet or to any other IP network, you can choose your own network numbers as long as they conform to the above rules.

If your networks are isolated from the Internet, e.g. only between your two branch offices, you can assign any IP Addresses to hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP Addresses specifically for private (stub) networks:

Class Beginning

Ending Address

Address

A 10.0.0.0 10.255.255.255 B 172.16.0.0 172.31.255.255 C 192.168.0.0 192.168.255.255

It is recommended that you choose private network IP Addresses from the above list. For more information on address assignment, refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.

Subnet Mask

In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown below.

IP Class Subnet Mask

Class A 255.0.0.0 Class B 255.255.0.0 Class C 255.255.255.0

Subnet mask settings other than those listed above add significance to the interpretation of bits in the IP address. The bits of the subnet mask correspond directly to the bits of the IP address. Any bit an a subnet mask that is to correspond to a net ID bit in the IP address must be set to 1.

DSL-500 Firmware Upgrade Utility

You can update system firmware using the DSL-500 Firmware Upgrade Utility. To upgrade the Router’s firmware you must have installed this software on the PC you wish to use for this purpose. Install the utility by clicking the file titled

setup.exe

It is recommended that the PC be directly connected to the Router using a crossed cable, however you may upgrade it through the LAN from a remote host.

DSL-500 ADSL Router User’s Guide

Enter the password and click OK.

In the new window you will see the MAC address of the Router and the IP address of the PC you are using. The PC and the Router must be on the same subnet for the upgrade to be completed. The upgrade utility will suggest a new IP address to be temporarily assigned to the device during the firmware upgrade procedure. Check the suggested IP address listed for the Router to be sure that it does not conflict with any existing IP addresses on your network. To change the temporary IP address of the Router, type in an available IP address in the space provided. You should change only the host portion of the address.

To upload the new firmware to the selected Router click the ‘Upgrade’ button. The utility will automatically load the new firmware. During the upgrade process it is important that you allow the entire file to load onto the device. Do not turn off the Router while the flash memory is being updated. A warning will appear during the upgrade reminding you not to power off the device.

When the new firmware has been successfully loaded a new window will inform you of the upgrade and tell you that the Router has been restarted. Click OK to proceed.
