    For access to the Internet, you need to contract with an Internet service provider (ISP) for a single-user Internet access account using ADSL. The Model DG814 DSL Modem Internet Gateway includes a built-in ADSL modem that connects directly to your ADSL line.

  • Page 39: Login Protocols

    For a single-user Internet account, your ISP supplies TCP/IP configuration information (such as IP address, subnet mask and default gateway) and VPI and VCI multiplexing information for one PC. Your ISP may also provide other login information, such as User Name and Password, in the case where the PPPoE or PPPoA protocol is required.

  • Page 40: Obtaining Isp Configuration Information (Windows)

    If any of these items are dynamically supplied by the ISP, your gateway automatically acquires them. If an ISP technician configured your PC during the installation of the broadband modem, or if you configured it using instructions provided by your ISP, you need to copy configuration information from your PC’s Network TCP/IP Properties window (or Macintosh TCP/IP Control Panel) before reconfiguring your PC for use with the gateway.

  • Page 41: Obtaining Isp Configuration Information (Macintosh)

    Obtaining ISP Configuration Information (Macintosh) As mentioned above, you may need to collect configuration information from your Macintosh so that you can use this information when you configure the Model DG814 gateway. Following this procedure is only necessary when your ISP does not dynamically supply the account information. To get the information you need to configure the gateway for Internet access: From the Apple menu, select Control Panels, then TCP/IP.

  • Page 92: Routing Information Protocol

    Routing Information Protocol One of the protocols used by a router to build and maintain a picture of the network is the Routing Information Protocol (RIP). Using RIP, routers periodically update one another and check for changes to add to the routing table. The Model DG814 gateway supports both the older RIP-1 and the newer RIP-2 protocols.

  • Page 93: Figure B-1. Three Main Address Classes

    Class A Network Class B Network Class C Network Figure B-1. Three Main Address Classes The five address classes are: • Class A Class A addresses can have up to 16,777,214 hosts on a single network. They use an eight-bit network number and a 24-bit node number.

  • Page 94: Netmask

    This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network. For each unique value of the network portion of the address, the base address of the range (host address of all zeros) is known as the network address and is not usually assigned to a host. Also, the top address of the range (host address of all ones) is not assigned, but is used as the broadcast address for simultaneously sending a packet to all hosts with the same network address.

  • Page 95: Figure B-2. Example Of Subnetting A Class B Address

    Subnet addressing allows us to split one IP network address into smaller multiple physical networks known as subnetworks. Some of the node numbers are used as a subnet number instead. A Class B address gives us 16 bits of node numbers translating to 64,000 nodes. Most organizations do not use 64,000 nodes, so there are free bits that can be reassigned.
  • Page 96 The following table lists the additional subnet mask bits in dotted-decimal notation. To use the table, write down the original class netmask and replace the 0 value octets with the dotted-decimal value of the additional subnet bits. For example, to partition your Class C network with subnet mask 255.255.255.0 into 16 subnets (4 bits), the new subnet mask becomes 255.255.255.240.

  • Page 97: Private Ip Addresses

    NETGEAR strongly recommends that you configure all hosts on a LAN segment to use the same netmask for the following reasons: • So that hosts recognize local IP broadcast packets When a device broadcasts to its segment neighbors, it uses a destination address of the local network address with all ones for the host address.

    The router accomplishes this address sharing by translating the internal LAN IP addresses to a single address that is globally unique on the Internet. The internal LAN IP addresses can be either private addresses or registered addresses. For more information about IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).

    Many of the resources on the Internet can be addressed by simple descriptive names such as www.NETGEAR.com. This addressing is very helpful at the application level, but the descriptive name must be translated to an IP address in order for a user to actually contact the resource. Just as...

    Reference Manual for the Model DG814 DSL Modem Internet Gateway IP Configuration by DHCP When an IP-based local area network is installed, each PC must be configured with an IP address. If the PCs need to access the Internet, they should also be configured with a gateway address and one or more DNS server addresses.

  • Page 101: Ethernet Cabling

    Ethernet Cabling Although Ethernet networks originally used thick or thin coaxial cable, most installations currently use unshielded twisted pair (UTP) cabling. The UTP cable contains eight conductors, arranged in four twisted pairs, and terminated with an RJ45 type connector. A normal "straight-through" UTP Ethernet cable follows the EIA568B standard wiring and pinout as described in Table B-3.

    • Crossover cable A crossover cable is a special cable in which the transmit and receive pairs are exchanged at one of the two cable connectors. Crossover cables are often unmarked as such, and must be identified by comparing the two connectors. Since the cable connectors are clear plastic, it is easy to place them side by side and view the order of the wire colors on each.

    Domain names are of the form of a registered entity name plus one of a number of predefined top level suffixes such as .com, .edu, .uk, etc. For example, in the address mail.NETGEAR.com, mail is a server name and NETGEAR.com is the domain.
  • Page 104 IP Address A four-byte number uniquely defining each host on the Internet. Ranges of addresses are assigned by Internic, an organization formed for this purpose. Usually written in dotted-decimal notation with periods separating the bytes (for example, 134.177.244.57). IPSec Internet Protocol Security. IPSec is a series of guidelines for securing private information transmitted over public networks.
