A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks (such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.

    Chapter 6 Broadband WAN IP Address The WAN IP address is an IP address for the ZyXEL Device, which makes it accessible from an outside network. It is used by the ZyXEL Device to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the ZyXEL Device tries to access the Internet.

    H A P T E R IGMP 14.1 Overview Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient) or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to just a group of hosts on the network. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group - it is not used to carry user data.

NAT traversal allows you to set up an IKE SA when there are NAT routers between the two IPSec routers.

  • Page 352 Appendix B IP Addresses and Subnetting Notation Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet.

The subnet mask is now 25 bits (255.255.255.128 or /25).
  • Page 354 Appendix B IP Addresses and Subnetting In a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).

    P P E N D I X Wireless LANs Wireless LAN Topologies This section discusses ad-hoc and infrastructure wireless LAN topologies. Ad-hoc Wireless LAN Configuration The simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless adapters (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an ad-hoc network or Independent Basic Service Set (IBSS).
  • Page 370 Appendix D Wireless LANs with each other. When Intra-BSS is disabled, wireless client A and B can still access the wired network but cannot communicate with each other. Figure 197 Basic Service Set An Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network.
  • Page 371 Appendix D Wireless LANs An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless clients within the same ESS must have the same ESSID in order to communicate. Figure 198 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by wireless devices to transmit and receive data.
  • Page 372 Appendix D Wireless LANs hidden node. Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other.
  • Page 373: Fragmentation Threshold

    Wireless security is vital to your network to protect wireless communication between wireless clients, access points and the wired network. Wireless security methods available on the ZyXEL Device are data encryption, wireless client authentication, restricting access by device MAC address and hiding the ZyXEL Device identity.
  • Page 374 Wi-Fi Protected Access (WPA) WPA2 Most Secure Note: You must enable the same wireless security settings on the ZyXEL Device and on all wireless clients that you want to associate with it.

  • Page 375 Appendix D Wireless LANs • Authorization Determines the network services available to authenticated users once they are connected to the network. • Accounting Keeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless client and the network RADIUS server.
  • Page 376 Appendix D Wireless LANs EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication.
  • Page 377: Dynamic Wep Key Exchange

    Appendix D Wireless LANs TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP) Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity.
  • Page 378: Wpa And Wpa2

    Appendix D Wireless LANs WPA and WPA2 Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA or WPA2 and WEP are improved data encryption and user authentication.
  • Page 379 Appendix D Wireless LANs The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped.

However, you must run Windows XP to use it. WPA(2) with RADIUS Application Example To set up WPA(2), you need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret.
  • Page 381: Security Parameters Summary

    Appendix D Wireless LANs The AP checks each wireless client's password and allows it to join the network only if the password matches. The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys.
