Appendix B Network and Routing Basics This chapter provides an overview of IP networks, routing, and wireless networking. Related Publications As you read this document, you may be directed to various RFC documents for further information. An RFC is a Request For Comment (RFC) published by the Internet Engineering Task Force (IETF), an open organization that defines the architecture and operation of the Internet. The RFC documents outline and define the standard protocols and procedures for the Internet.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway What is a Router? A router is a device that forwards traffic between networks based on network layer information in the data and on routing tables maintained by the router. In these routing tables, a router builds up a logical picture of the overall network by gathering and exchanging information with other routers in the network. Using this information, the router chooses the best path for forwarding network traffic.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway The latter version is easier to remember and easier to enter into your computer. In addition, the 32 bits of the address are subdivided into two parts. The first part of the address identifies the network, and the second part identifies the host node or station on the network. The dividing point may vary depending on the address range and the application. There are five standard classes of IP addresses.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway • Class C Class C addresses can have 254 hosts on a network. Class C addresses use 24 bits for the network address and eight bits for the node. They are in this range: 192.0.1.x to 223.255.254.x. • Class D Class D addresses are used for multicasts (messages sent to many hosts). Class D addresses are in this range: 224.0.0.0 to 239.255.255.255. • Class E Class E addresses are for experimental use.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway As a shorter alternative to dotted-decimal notation, the netmask may also be expressed in terms of the number of ones from the left. This number is appended to the IP address, following a backward slash ( / ), as “/n.” In the example, the address could be written as 192.168.170.237/24, indicating that the netmask is 24 ones followed by 8 zeros.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Although the preceding example uses the entire third octet for a subnet address, note that you are not restricted to octet boundaries in subnetting. To create more network numbers, you need only shift some bits from the host address to the network address. For instance, to partition a Class C network number (192.68.135.0) into two, you shift one bit from the host address to the network address. The new netmask (or subnet mask) is 255.255.

Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Single IP Address Operation Using NAT In the past, if multiple PCs on a LAN needed to access the Internet simultaneously, you had to obtain a range of IP addresses from the ISP. This type of Internet account is more costly than a single-address account typically used by a single user with a modem, rather than a router. The DG824M gateway employs an address-sharing method called Network Address Translation (NAT).
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway This scheme offers the additional benefit of firewall-like protection because the internal LAN addresses are not available to the Internet through the translated connection. All incoming inquiries are filtered out by the router. This filtering can prevent intruders from probing your system. However, using port forwarding, you can allow one PC (for example, a Web server) on your local network to be accessible to outside users.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Domain Name Server 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.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway 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 as described in Table 7-1. Table 7-1.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Cable Quality A twisted pair Ethernet network operating at 10 Mbits/second (10BASE-T) will often tolerate low quality cables, but at 100 Mbits/second (10BASE-Tx) the cable must be rated as Category 5, or "Cat 5", by the Electronic Industry Association (EIA). This rating will be printed on the cable jacket. A Category 5 cable will meet specified requirements regarding loss and crosstalk.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Stateful Packet Inspection Unlike simple Internet sharing routers, a firewall uses a process called stateful packet inspection to ensure secure firewall filtering to protect your network from attacks and intrusions. Since user-level applications such as FTP and Web browsers can create complex patterns of network traffic, it is necessary for the firewall to analyze groups of network connection "states.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Ad Hoc Mode (Peer-to-Peer Workgroup) In an ad hoc network, computers are brought together as needed; thus, there is no structure or fixed points to the network - each node can generally communicate with any other node. There is no Access Point involved in this configuration.
Reference Manual for the Model DG824M Wireless ADSL Modem Gateway Authentication and WEP Encryption The absence of a physical connection between nodes makes the wireless links vulnerable to eavesdropping and information theft. To provide a certain level of security, the IEEE 802.11 standard has defined two types of authentication methods, Open System and Shared Key. With Open System authentication, a wireless PC can join any network and receive any messages that are not encrypted.
