Appendix B Network, Routing, Firewall, and Basics This chapter provides an overview of IP networks, routing, and networking. Related Publications As you read this document, you may be directed to various Request For Comment (RFC) documents for further information. An RFC is a document published by the Internet Engineering Task Force (IETF), an open organization that defines the architecture and operation of the Internet.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Routers vary in performance and scale, number of routing protocols supported, and types of physical WAN connection they support. The 54 Mbps Wall-Plugged Wireless Range Extender WGX102 is a small office router that routes the IP protocol over a single-user broadband connection.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 There are five standard classes of IP addresses. These address classes have different ways of determining the network and host sections of the address, allowing for different numbers of hosts on a network. Each address type begins with a unique bit pattern, which is used by the TCP/IP software to identify the address class.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 • 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. This addressing structure allows IP addresses to uniquely identify each physical network and each node on each physical network.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Subnet Addressing By looking at the addressing structures, you can see that even with a Class C address, there are a large number of hosts per network. Such a structure is an inefficient use of addresses if each end of a routed link requires a different network number. It is unlikely that the smaller office LANs would have that many devices. You can resolve this problem by using a technique known as subnet addressing.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Note: The number 192.68.135.127 is not assigned because it is the broadcast address of the first subnet. The number 192.68.135.128 is not assigned because it is the network address of the second subnet. The following table lists the additional subnet mask bits in dotted-decimal notation.

Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Single IP Address Operation Using NAT In the past, if multiple computers 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.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 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.
Reference Manual for the 54 Mbps Wall-Plugged Wireless Range Extender WGX102 Domain Name Server Many of the resources on the Internet can be addressed by simple descriptive names such as http://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 54 Mbps Wall-Plugged Wireless Range Extender WGX102 What is a Firewall? A firewall is a device that protects one network from another, while allowing communication between the two.

Appendix D Wireless Networking Basics This chapter provides an overview of Wireless networking. Wireless Networking Overview The WGU624 wireless router conforms to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standard for wireless LANs (WLANs) and a product update will bring the WGU624 into conformance to the 802.11g standard when it is ratified. On an 802.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 In the infrastructure mode, the wireless access point converts airwave data into wired Ethernet data, acting as a bridge between the wired LAN and wireless clients. Connecting multiple Access Points via a wired Ethernet backbone can further extend the wireless network coverage. As a mobile computing device moves out of the range of one access point, it moves into the range of another.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Authentication and WEP 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.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 • Shared Key Authentication requires that the station and the access point have the same WEP Key to authenticate. These two authentication procedures are described below. Open System Authentication The following steps occur when two devices use Open System Authentication: 1. The station sends an authentication request to the access point. 2. The access point authenticates the station. 3.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 5. The station connects to the network. If the decrypted text does not match the original challenge text (i.e., the access point and station do not share the same WEP Key), then the access point will refuse to authenticate the station and the station will be unable to communicate with either the 802.11 network or Ethernet network. This process is illustrated in below. 802.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 3. Use WEP for Authentication and Encryption: A transmitting 802.11 device encrypts the data portion of every packet it sends using a configured WEP Key. The receiving 802.11 device decrypts the data using the same WEP Key. For authentication purposes, the 802.11 network uses Shared Key Authentication. Note: Some 802.11 access points also support Use WEP for Authentication Only (Shared Key Authentication without data encryption).
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 WEP Configuration Options The WEP settings must match on all 802.11 devices that are within the same wireless network as identified by the SSID. In general, if your mobile clients will roam between access points, then all of the 802.11 access points and all of the 802.11 client adapters on the network must have the same WEP settings.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 The radio frequency channels used are listed in Table 9-1: Table 9-1. 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 Double 108 Mbps Wireless Firewall Router WGU624 The IEEE introduced the WEP as an optional security measure to secure 802.11b (Wi-Fi) WLANs, but inherent weaknesses in the standard soon became obvious. In response to this situation, the Wi-Fi Alliance announced a new security architecture in October 2002 that remedies the shortcomings of WEP. This standard, formerly known as Safe Secure Network (SSN), is designed to work with existing 802.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 How Does WPA Compare to IEEE 802.11i? WPA will be forward compatible with the IEEE 802.11i security specification currently under development. WPA is a subset of the current 802.11i draft and uses certain pieces of the 802.11i draft that are ready to bring to market today, such as 802.1x and TKIP. The main pieces of the 802.11i draft that are not included in WPA are secure IBSS (Ad-Hoc mode), secure fast handoff (for specialized 802.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 The primary information conveyed in the Beacon frames is the authentication method and the cipher suite. Possible authentication methods include 802.1X and Pre-shared key. Pre-shared key is an authentication method that uses a statically configured pass phrase on both the stations and the access point.

Information elements include the required authentication method (802.1x or Pre-shared key) and the preferred cipher suite (WEP, TKIP, or AES).
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 3. The client sends an EAP-response packet containing the identity to the authentication server. The access point responds by enabling a port for passing only EAP packets from the client to an authentication server located on the wired side of the access point.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Temporal Key Integrity Protocol (TKIP) WPA uses TKIP to provide important data encryption enhancements including a per-packet key mixing function, a message integrity check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism. TKIP also provides for the following: • • • The verification of the security configuration after the encryption keys are determined.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Is WPA Perfect? WPA is not without its vulnerabilities. Specifically, it is susceptible to denial of service (DoS) attacks. If the access point receives two data packets that fail the message integrity code (MIC) within 60 seconds of each other, then the network is under an active attack, and as a result, the access point employs counter measures, which include disassociating each station using the access point.
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Changes to Wireless Access Points Wireless access points must have their firmware updated to support the following: • • • • • The new WPA information element To advertise their support of WPA, wireless APs send the beacon frame with a new 802.11 WPA information element that contains the wireless AP's security configuration (encryption algorithms and wireless security configuration information).
Reference Manual for the Double 108 Mbps Wireless Firewall Router WGU624 Microsoft has worked with many wireless vendors to embed the WPA firmware update in the wireless adapter driver. So, to update your Microsoft Windows wireless client, all you have to do is obtain the new WPA-compatible driver and install the driver. The firmware is automatically updated when the wireless network adapter driver is loaded in Windows.
