About This User’s Guide
This user’s guide provides instructions on how to install the DSL-G804V Wireless ADSL Router and use it to connect a computer or Ethernet LAN to the Internet.
If you are using a computer with a functioning Ethernet port, the quickest and easiest way to set up the DSL-
G804V is to insert the Installation CD into the CD-ROM drive of your computer and follow the instructions provided in the Quick Installation Guide.
Before You Start
Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and equipment on hand before beginning the installation.
Installation Overview
The procedure to install the Router can be described in general terms in the following steps:
1. Gather information and equipment needed to install the device. Before you begin the actual installation make sure you have all the necessary information and equipment.
2. Install the hardware, that is, connect the cables (Ethernet and telephone) to the device and connect the power adapter.
3. Check the IP settings on your computer and change them if necessary so the computer can access the web-based software built into the Router.
4. Use the web-based management software to configure the device to suit the requirements of your ADSL account.
Installation Requirements
In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be sure to keep this information safe and private.
Low Pass Filters
Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more information about the use of low pass filters with your installation.
Operating Systems
The DSL-G804V uses an HTML-based web interface for setup and management. The web configuration manager may be accessed using any operating system capable of running web browser software, including
Windows 98, Windows NT, Windows 2000, Windows XP and Me.
Web Browser
Any common web browser can be used to configure the Router using the web configuration management software. The program is designed to work best with more recently released browsers such as Opera, Microsoft
Internet Explorer® version 5.0, Netscape Navigator® version 4.5, or later versions. The web browser must have
JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not been disabled by other software (such as virus protection or web user security packages) that may be running on your computer. v
DSL-G804V Wireless ADSL Router User’s Guide
Ethernet Port (NIC Adapter)
Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the installation instructions that come with the Ethernet NIC adapter.
Additional Software
It may be necessary to install software on your computer that enables the computer to access the Internet.
Additional software must be installed if you are using the device a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored on another computer or gateway device, not in the Router itself.
If your ADSL service is delivered through a PPPoE, PPPoA or CLIP (IPoA) connection, the information needed to establish and maintain the Internet connection can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some settings in the device, including account information used to identify and verify the connection.
All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or NIC configuration that may be required.
About CLIP Connections (RFC 1577)
Classical IP over ATM (CLIP) connections may require global IP settings for the device. Your service provider will give you IP settings information if needed. Some CLIP connections function like peer-to-peer connections and therefore do not require IP settings on the WAN interface. vi

Introduction
This section provides a brief description of the Router, its associated technologies and a list of Router features.
Router Description and Operation
The DSL-G804V Wireless ADSL Router is designed to provide a simple and cost-effective ADSL Internet connection for individual computers through the Ethernet ports, or use it to bridge your Ethernet LAN to the
Internet. The DSL-G804V combines the benefits of high-speed ADSL technology and LAN IP management in one compact and convenient package. ADSL technology enables many interactive multi-media applications such as video conferencing and collaborative computing.
The Router is easy to install and use. The DSL-G804V connects to computers or an Ethernet LAN via a standard
Ethernet interface. The ADSL connection is made using ordinary twisted-pair telephone line with standard connectors. Multiple PCs can be networked and connected to the Internet using a single Wide Area Network
(WAN) interface and single global IP address.
It supports the latest ADSL2/2+ technology enabling high-speed data rates of up to 24Mbps, Its powerful QoS feature for traffic priority and bandwidth management, and security features including multiple VPN tunnels with 3DES make the device a perfect mate to the office user or for anyone who has the compelling needs to transmit sensitive data more securely. With integrated 54Mbps 802.11g Access Point in this device, the router brings up the productivity and mobility to office users.
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 for your private network.
What is ADSL?
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.
ADSL greatly increases the signal carrying capacity of copper telephone lines without interfering with regular telephone services. For the ADSL user, this means faster downloads and more reliable connectivity. ADSL devices make it possible to enjoy benefits such as high-speed Internet access 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 and up to 640 Kbps upstream, depending on local telephone line conditions. A secure point-to-point connection is established between the user and the central office of the service provider.
D-Link ADSL devices incorporate the recommendations of the ADSL Forum regarding framing, data format, and upper layer protocols.

Network Connections
Network connections are provided through the ADSL port and the four Ethernet ports on the back of the Router.
See the Rear Panel diagram above and the illustrations below for examples.
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. 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 RJ-11 wall socket. If you are using a low pass filter device, follow the instructions included with the device or given to you by your service provider. The ADSL connection represents the WAN interface, the connection to the Internet. It is the physical link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of 10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at speeds higher than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X).
Follow standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the Router directly to a PC or server use a normal straight-through cable. You should use a crossed cable when connecting the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an uplink (MDI-II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable as shown in the diagram below:
If you wish to reserve the uplink port on the switch or hub for another device, connect to any on the other
MDI-X ports (1x, 2x, etc.) with a crossed cable.

Basic Router Configuration
The first time you setup the Router it is recommended that you configure the WAN connection using a single computer making sure that both the computer and the Router are not connected to the LAN. Once the WAN connection is functioning properly, you may continue to make changes to Router configuration including IP settings and DHCP setup. This chapter is concerned with using your computer to configure the WAN connection.
The following chapter describes the various menus used to configure and monitor the Router including how to change IP settings and DHCP server setup.
Wan Configuration Summary
1. Connect to the Router To configure the WAN connection used by the Router it is first necessary to communicate with the Router through its management interface, which is HTML-based and can be accessed using a web browser. To access the management software your computer must be able to
“see” the Router. Your computer can see the Router if it is in the same “neighborhood” or subnet as the
Router. This is accomplished by making sure your computer has IP settings that place it in the same subnet as the Router. The easiest way to make sure your computer has the correct IP settings is to configure it to use the DHCP server in the Router. The next section describes how to change the IP configuration for a computer running a Windows operating system to be a DHCP client.
2. Configure the WAN Connection Once your are able to access the configuration software you can proceed to change the settings required to establish the ADSL connection and connect to the service provider’s network. There are different methods used to establish the connection to the service provider’s network and ultimately to the Internet. You should know what Encapsulation and connection type you are required to use for your ADSL service. It is also possible that you must change the PVC settings used for the ADSL connection. Your service provider should provide all the information you need to configure the WAN connection.
Configuring IP Settings on Your Computer
In order to configure your system to receive IP settings from the Router it must first have the TCP/IP protocol installed. If you have an Ethernet port on your computer, it probably already has TCP/IP protocol installed. If you are using Windows XP the TCP/IP is enabled by default for standard installations. Below is an illustrated example of how to configure a Windows XP system to automatically obtain IP settings from the Router.
Following this example is a step-by-step description of the procedures used on the other Windows operating systems to first check if the TCP/IP protocol has been installed; if it is not, instructions are provided for installing it. Once the protocol has been installed you can configure the system to receive IP settings from the
Router.
For computers running non-Windows operating systems, follow the instructions for your OS that configure the system to receive an IP address from the Router, that is, configure the system to be a DHCP client.
Note
If you are using this Router to provide Internet access for more than one computer, you can use these instructions later to change the IP settings for the other computers.
However, you cannot use the same IP address since every computer must have its own
IP address that is unique on the local network.

Five options to choose from: Auto, 10M half-duplex, 10M full-duplex, 100M half-duplex or 100M full-duplex. Sometimes, there are Ethernet compatibility problems with legacy Ethernet devices, and you can configure different types to solve compatibility issues. The default is Auto, which users should keep unless there are specific problems with PCs not being able to access your
LAN.
TOS, Type of Services, is the 2 nd
octet of an IP packet. Bits 6-7 of this octet are reserved and bit 0-2 are used to specify the priority (precedence) of the packet, and bits 3-5 are specified the delay, throughput and reliability.
This feature uses bits 0-2 to classify the packet’s priority. If the packet is high priority, it will flow first. Therefore, when this feature is enabled, the router’s
Ethernet switch will check the 2 nd
octet of each IP packet. If the value in the
Precedence of TOS field matches the checked values in the table (0 to 7), this packet will be treated as high priority.

DHCP
DHCP stands for Dynamic Host Control Protocol. The DHCP protocol allows your router to dynamically assign
IP addresses to PCs on your network if they are configured to obtain IP addresses automatically.
Figure 3-13. Home – DHCP Server
Disable DHCP
The DHCP Server is disabled; you will need to manually assign a fixed IP address to each PCs on your network, and set the default gateway for each PCs to the IP address of the router.
DHCP Server
You can configure parameters of the DHCP Server including the IP pool (starting IP address and ending IP address to be allocated to PCs on your network), lease time for each assigned IP address (the period of time the
IP address assigned will be valid), DNS IP address and the gateway IP address. These details are sent to the
DHCP client (i.e. your PC) when it requests an IP address from the DHCP server. If you check “Use Router as a
DNS Server”, the ADSL Router will perform the domain name lookup, find the IP address from the outside network automatically and forward it back to the requesting PC in the LAN (your Local Area Network).
28
DSL-G804V Wireless ADSL Router User’s Guide
Static DHCP

DNS Relay Configuration
A Domain Name System (DNS) contains a mapping table for domain name and IP addresses. On the Internet, every host has a unique and user-friendly name (domain name) such as www.helloworld.com and an IP address.
An IP address is a 32-bit number in the form of xxx.xxx.xxx.xxx, for example 192.168.1.1. You can think of an IP address as a telephone number for devices on the Internet, and the DNS will allow you to find the telephone number for any particular domain name. As an IP Address is hard to remember, the DNS converts the friendly name into its equivalent IP Address.
Figure 3-16. Home – DNS Configuration
You can obtain a Domain Name System (DNS) IP address automatically if your ISP has provided it when you logon, check the Enable box. Usually when you choose PPPoE or PPPoA as your WAN - ISP protocol, the ISP will provide the DNS IP address automatically. You may leave the configuration field blank.
Alternatively, your ISP may provide you with an IP address of their DNS. If this is the case, you must enter the
DNS IP address manually

Wireless, ADSL, IP QoS, Time Schedule, Email, Device, IGMP and Logout.
Virtual Server
NAT can act as a “natural” Internet firewall; your router protects your network from being accessed by outside users. When using NAT, all incoming connection attempts will point to your router, unless you specifically create Virtual Server entries to forward those ports to a PC on your network. Virtual Sever utilizes protocol,
TCP/IP and UDP types, which is port with 16-bit number that used to identify which the application program
(usually a server) should be delivered from an incoming connections should be delivered to. Some ports have numbers that are pre-assigned to them by the IANA (the Internet Assigned Numbers Authority), and these are referred to as “well-known ports”. Servers follow the well-known port assignments so clients can locate them.
Note
If you have disabled the NAT option in the WAN-ISP section, the Virtual Server function will hence be invalid.
Note
If the DHCP server option is enabled, you have to be very careful in assigning the IP addresses of the virtual servers in order to avoid conflicts. The easiest way of configuring Virtual Servers is to manually assign static IP address to each virtual server PC, with an address that does not fall into the range of IP addresses that are to be issued by the DHCP server. You can configure the virtual server IP address manually, but it must still be in the same subnet as the router.
31
DSL-G804V Wireless ADSL Router User’s Guide
Add Virtual Server
When your router needs to allow outside users to access internal servers, e.g. a web server, FTP server, Email server or game server, the router can act as a “virtual server”. You can set up a local server with a specific port number for the service to use, e.g. web/HTTP (port 80), FTP (port 21), Telnet (port 23), SMTP (port 25), or
POP3 (port 110). When an incoming access request to the router for a specified port is received, it will be forwarded to the corresponding internal server.

Intrusion Detection.
The router’s Intrusion Detection System (IDS) is used to detect hacker attacks and intrusion attempts from the
Internet. If the IDS function of the firewall is enabled, inbound packets are filtered and blocked depending o n whether they are detected as p ossible hacker attacks, intrusion attempts or other connections that the router d etermines to be suspicious.

Diffie-Hellman is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communication channel (i.e. over the Internet). There are three modes, MODP 768-bit, MODP 1024-bit and
MODP 1536-bit. MODP stands for Modular Exponentiation Groups.
This is for the Internet Key Exchange (IKE) protocol, a string from 4 to 128 characters. Both sides should use the same key. IKE is used to establish a shared security policy and authenticated keys for services (such as IPSec) that require a key. Before any IPSec traffic can be passed, each router must be able to verify the identity of its peer. This can be done by manually entering the pre-shared key into both sides (router or hosts).

DDNS (Dynamic DNS)
The Dynamic DNS function allows you to alias a dynamic IP address to a static hostname, allowing users whose
ISP does not assign them a static IP address to use a domain name. This is especially useful for hosting servers via your ADSL connection, so that anyone wishing to connect to you may use your domain name, rather than having to use your dynamic IP address, which changes from time to time. This dynamic IP address is the WAN
IP address of the router, which is assigned to you by your ISP.

A WEP encryption algorithm is defined by a set of respective Key and Key String for the wireless network.
Figure 4-21. Wireless Security – WEP
Parameter Description
WEP Authentication
Three types of authentication are available, Open System, Shared Key and
Open System/ShareKey (Both).
Open System: Authentication is a void authentication; it is easy to use. As long as the wireless client uses the same WEP key will be able to communicate with router’s Access Point. The AP will remain visible to all devices on the network.
Share Key: It is more secure than the Open System. Wireless client must use the same authentication and the Web Key to be able to communicate with router’s Access Point.
Open System / Share Key (Both): With this setting both open and share key are employed. Wireless client may have selected open or share key setting and still can get access to the Access point, only if correct WEP Key is presented.
WEP Encryption
Default Used WEP
Key (0-3)
To prevent unauthorized wireless stations from accessing data transmitted over the network, the router offers highly secure data encryption, known as
WEP. If you require high security for transmissions, there are two alternatives to select from: WEP 64 and WEP 128. WEP 128 will offer increased security over WEP 64.
Enter the key to encrypt wireless data. To allow encrypted data transmission, the WEP Encryption Key values on all wireless stations must be the same as the router. There are four keys for your selection. The input format is in HEX style, 5 and 13 HEX codes are required for WEP64 and WEP128 respectively, the separator is “-“. For example, using WEP64, 11-22-33-44-55 is a valid key, whilst 1122334455 is invalid.

For ADSL connection, this mode will automatically detect your ADSL line code,
G.dmt, G.lite, and T1.413. But in some area, multimode cannot detect the
ADSL line code well. If it is the case, please adjust the ADSL line code to
G.dmt or T1.413 first. If it still fails, please try the other values such as ALCTL,
ADI, etc. For ADSL2 connection, this mode automatically detects your line code to G.DMT.Bis.

IP QoS
IP QoS function helps you to control your network traffic for each application from LAN (Ethernet and/or
Wireless) to WAN (Internet). It facilitates you to control the different quality and speed of throughput for each application when the system is running with full loading of upstream.
You can find three items under the QoS section: Prioritization and Outbound / Inbound IP Throttling
(bandwidth management).
Packet Prioritization
Prioritization categorizes in High (utilized 60% of the total bandwidth), Normal (utilized 30% of the total bandwidth), Low (utilized 10% of the total bandwidth).

Example:
A User changes HTTP port number to 100, specifies their own IP address of 192.168.0.55, and sets the logout time to be 100 seconds. The router will only allow User A access from the IP address 192.168.0.55 to logon to the Web GUI by typing: http://192.168.0.1 in their web browser. After 100 seconds, the device will automatically logout User A. (192.168.0.1 is your router IP address).

IP Address Setup
The DSL-G804V is designed to provide network administrators maximum flexibility for IP addressing on the
Ethernet LAN. The easiest IP setup choice in most cases is to let the Router do it using DHCP, which is enabled by default. This appendix briefly describes various options including DHCP, used for IP setup on a LAN. If you are new to IP networking, the next appendix provides some background information on basic IP concepts.
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 is shipped with a preset default IP address setting of 192.168.1.1 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
Manually configuring IP settings for the LAN means you must manually set an IP address, subnet mask and IP address of the default gateway (the Router’s IP address) on each networked computer. The example listed below describes IP configuration for computers running Windows 95 or Windows 98. Regardless of what operating system is used on each workstation, the three network IP settings must be defined so the network interface used by each workstation can be identified by the Router, and vice versa. For detailed information about configuring your workstations IP settings, consult the user’s guide included with the operating system or the network interface card (NIC).
1. In Windows 95/98, click on the Start button, go to Settings and choose Control Panel.
2. In the window that opens, double-click on the Network icon.
3. Under the Configuration tab, select the TCP/IP component and click Properties. for IP settings on a Class C network.

Computer #3
192.168.0.4 255.255.255.0 192.168.1.1
IP Setup - Example #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. 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
90
DSL-G804V Wireless ADSL Router User’s Guide address (each computer must have a unique address to distinguish it on the network). The IP address scheme used in Example #1 can be used for any LAN that requires up to 253 separate IP addresses (excluding the
Router). Notice 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.

The second way to use the default settings is to allow the Router to automatically assign IP settings for workstation 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
When planning your LAN IP address setup, you may use any scheme allowed by rules that govern IP assignment.
It may be more convenient or easier to remember an IP scheme that use a different address for the Router. Or you may be installing the Router on a network that has already established the IP settings. Changing the IP address is a simple matter and can be done using the web manager (see LAN IP Address in Chapter 5). If you are incorporating the Router into a LAN with an existing IP structure, be sure to disable the DHCP function. Also, consider the effects of the NAT function which is enable by default.
An IP addressing scheme commonly used for Ethernet LANs establishes 10.0.0.1 as the base address for the network. Using Example #2 below, the Router is assigned the base address 10.0.0.1 and the remaining addresses are assigned manually or using DHCP.

These two examples are only examples you can use to help you get started. If you are interested in more advanced information on how to use IP addressing on a LAN there are numerous resources freely available on the Internet. There are also many books and chapters of books on the subject of IP address assignment, IP networking and the TCP/IP protocol suite.

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.
92
DSL-G804V Wireless 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.
Class

192.0.1(.0) to 223.255.254(.0)
65,534
254
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 IP-capable port or interface — connected directly to that network.
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 Internet-assigned 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 Address Ending Address
A 10.0.0.0 10.255.255.255
B 172.16.0.0 172.31.255.255
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.
93

Subnet Mask
In the absence of subnetworks, standard TCP/IP addressing may be used by specifying subnet masks as shown below.
IP Class
Class A
Class B
Class C
Subnet Mask
255.0.0.0
255.255.0.0
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.

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 telephone 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.
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
Important: 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.
95
DSL-G804V Wireless ADSL Router User’s Guide
Line Splitter
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 RJ-11 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 – This port connects to the Modem.
Phone – This port connects to a telephone or other telephone device.
The diagram below illustrates the proper use of the splitter.
