  • Page 67: Encryption

    6.5.1 Encryption • Use WPA(2) security if you have WP(2)A-aware wireless clients and a RADIUS server. WPA(2) has user authentication and improved data encryption over WEP. • Use WPA(2)-PSK if you have WPA(2)-aware wireless clients but no RADIUS server. • If you don’t have WPA(2)-aware wireless clients, then use WEP key encrypting. A higher bit key offers better security at a throughput trade-off.

  • Page 68: Overview

    ZyXEL G-560 User’s Guide Figure 37 WEP Authentication Steps Open system authentication involves an unencrypted two-message procedure. A wireless station sends an open system authentication request to the AP, which will then automatically accept and connect the wireless station to the network. In effect, open system is not authentication at all as any station can gain access to the network.

  • Page 119: Appendix B 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 stations (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 120: Figure 99 Basic Service Set

    ZyXEL G-560 User’s Guide Figure 99 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. This wired connection between APs is called a Distribution System (DS). This type of wireless LAN topology is called an Infrastructure WLAN.

  • Page 121: Figure 100 Infrastructure Wlan

    Figure 100 Infrastructure WLAN Channel A channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference.

  • Page 122: Figure 101 Rts/Cts

    ZyXEL G-560 User’s Guide Figure 101 RTS/CTS When station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.

  • Page 123: Table 29 Ieee802.11G

    A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference. If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.

RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless station and the network RADIUS server.

  • Page 125: Figure 102 Eap Authentication

    EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, the access point helps a wireless station and a RADIUS server perform authentication.

  • Page 126: Wep Encryption

    ZyXEL G-560 User’s Guide However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication.

  • Page 127: Figure 103 Wep Authentication Steps

    WEP Authentication Steps Three different methods can be used to authenticate wireless stations to the network: Open System, Shared Key, and Auto. The following figure illustrates the steps involved. Figure 103 WEP Authentication Steps Open system authentication involves an unencrypted two-message procedure. A wireless station sends an open system authentication request to the AP, which will then automatically accept and connect the wireless station to the network.

  • Page 128: Table 30 Comparison Of Eap Authentication Types

    ZyXEL G-560 User’s Guide Dynamic WEP Key Exchange The AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed. If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen.
  • Page 129 TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes 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 regularly changes and rotates the encryption keys so that the same encryption key is never used twice.

    ZyWALL 5/35/70 Series User’s Guide Note: In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits. The number of “borrowed” host ID bits determines the number of subnets you can have. The remaining number of host ID bits (after “borrowing”) determines the number of hosts you can have on each subnet.

  • Page 137: Table 38 Subnet 1

    Example: Four Subnets The above example illustrated using a 25-bit subnet mask to divide a class “C” address space into two subnets. Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11. The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.
