Reference Manual for the Model CG814W Wireless Cable Modem Gateway Appendix B Networks, Routing, and Firewall Basics This chapter provides an overview of IP networks, routing, and firewalls. 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.
Reference Manual for the Model CG814W Wireless Cable 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 CG814W Wireless Cable 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 CG814W Wireless Cable 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 CG814W Wireless Cable 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 CG814W Wireless Cable 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 CG814W Wireless Cable Modem Gateway Table 6-2. Netmask Formats 255.255.255.0 /24 255.255.255.128 /25 255.255.255.192 /26 255.255.255.224 /27 255.255.255.240 /28 255.255.255.248 /29 255.255.255.252 /30 255.255.255.254 /31 255.255.255.
Reference Manual for the Model CG814W Wireless Cable 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 CG814W Gateway employs an address-sharing method called Network Address Translation (NAT).
Reference Manual for the Model CG814W Wireless Cable 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 CG814W Wireless Cable 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 CG814W Wireless Cable Modem Gateway What is a Firewall? A firewall is a device that protects one network from another, while allowing communication between the two. A firewall incorporates the functions of the NAT router, while adding features for dealing with a hacker intrusion or attack. Several known types of intrusion or attack can be recognized when they occur.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway Wireless Networking Overview The CG814W Gateway conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11b standard for wireless LANs (WLANs). On an 802.11b wireless link, data is encoded using direct-sequence spread-spectrum (DSSS) technology and is transmitted in the unlicensed radio spectrum at 2.5GHz. The maximum data rate for the wireless link is 11 Mbps, but it will automatically back down from 11 Mbps to 5.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway Network Name: Extended Service Set Identification (ESSID) The Extended Service Set Identification (ESSID) is one of two types of Service Set Identification (SSID). In an ad hoc wireless network with no access points, the Basic Service Set Identification (BSSID) is used. In an infrastructure wireless network that includes an access point, the ESSID is used, but may still be referred to as SSID.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway 6. The station sends an association request to the access point. 7. The access point associates with the station. 8. The station can now communicate with the Ethernet network through the access point. An access point must authenticate a station before the station can associate with the access point or communicate with the network. The IEEE 802.11b standard defines two types of authentication: Open System and Shared Key.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway Shared Key Authentication The following steps occur when two devices use Shared Key Authentication: 1. The station sends an authentication request to the access point. 2. The access point sends challenge text to the station. 3. The station uses its configured 64-bit or 128-bit default key to encrypt the challenge text, and sends the encrypted text to the access point. 4.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway Overview of WEP Parameters Before enabling WEP on an 802.11b network, you must first consider what type of encryption you require and the key size you want to use. Typically, there are three WEP Encryption options available for 802.11b products: 1. Do Not Use WEP: The 802.11b network does not encrypt data. For authentication purposes, the network uses Open System Authentication. 2. Use WEP for Encryption: A transmitting 802.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway When configured for 40-bit encryption, 802.11b products typically support up to four WEP Keys. Each 40-bit WEP Key is expressed as 5 sets of two hexadecimal digits (0-9 and A-F). For example, “12 34 56 78 90” is a 40-bit WEP Key. When configured for 128-bit encryption, 802.11b products typically support four WEP Keys but some manufacturers support only one 128-bit key.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway Wireless Channels IEEE 802.11 wireless nodes communicate with each other using radio frequency signals in the ISM (Industrial, Scientific, and Medical) band between 2.4 GHz and 2.5 GHz. Neighboring channels are 5 MHz apart. However, due to spread spectrum effect of the signals, a node sending signals using a particular channel will utilize frequency spectrum 12.5 MHz above and below the center channel frequency.
Reference Manual for the Model CG814W Wireless Cable Modem Gateway The radio frequency channels used are listed in Table 6-1: Table 6-1. 802.11 Radio Frequency Channels Channel Center Frequency Frequency Spread 1 2412 MHz 2399.5 MHz - 2424.5 MHz 2 2417 MHz 2404.5 MHz - 2429.5 MHz 3 2422 MHz 2409.5 MHz - 2434.5 MHz 4 2427 MHz 2414.5 MHz - 2439.5 MHz 5 2432 MHz 2419.5 MHz - 2444.5 MHz 6 2437 MHz 2424.5 MHz - 2449.5 MHz 7 2442 MHz 2429.5 MHz - 2454.5 MHz 8 2447 MHz 2434.
Reference Manual for the Model CG814W Wireless Cable 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 6-2. Table 6-2.
Reference Manual for the Model CG814W Wireless Cable 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).
