ZyAIR G-2000 Plus User’s Guide 1.2.2.4 802.11g Wireless LAN Standard The ZyAIR, complies with the 802.11g wireless standard and is also fully compatible with the 802.11b standard. This means an 802.11b radio card can interface directly with an 802.11g device (and vice versa) at 11 Mbps or lower depending on range. 802.11g has several intermediate rate steps between the maximum and minimum data rates.
Page 40: Firewall
ZyAIR G-2000 Plus User’s Guide 1.2.2.9 Firewall The ZyAIR employs a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The ZyAIR firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.
Page 41: Pppoe Support (Rfc2516)
ZyAIR G-2000 Plus User’s Guide 1.2.2.16 PPPoE Support (RFC2516) PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the ZyAIR is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual computers.
Page 42: Multicast
ZyAIR G-2000 Plus User’s Guide 1.2.2.22 Multicast Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way to deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236).

Page 80: Ess
ZyAIR G-2000 Plus User’s Guide Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.
Page 81: Wireless Lan Basics
ZyAIR G-2000 Plus User’s Guide Figure 23 Extended Service Set 6.2 Wireless LAN Basics Refer also to the Wizard Setup chapter for more background information on Wireless LAN features, such as channels. 6.2.1 RTS/CTS A hidden node occurs when two stations are within range of the same access point, but are not within range of each other.
Page 82: Fragmentation Threshold
ZyAIR G-2000 Plus User’s Guide Figure 24 RTS/CTS When station A sends data to the ZyAIR, it might not know that 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 83: Configuring Wireless
ZyAIR G-2000 Plus User’s Guide 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.

Page 138: What Nat Does
ZyAIR G-2000 Plus User’s Guide Note: NAT never changes the IP address (either local or global) of an outside host. 10.1.2 What NAT Does In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side.
Page 139: Nat Application
ZyAIR G-2000 Plus User’s Guide Figure 54 How NAT Works 10.1.4 NAT Application The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using IP Alias) behind the ZyAIR can communicate with three distinct WAN networks.

ZyAIR G-2000 Plus User’s Guide You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.

ZyAIR G-2000 Plus User’s Guide Figure 74 ZyAIR Firewall Application 14.4 Denial of Service Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources.
Page 182: Types Of Dos Attacks
ZyAIR G-2000 Plus User’s Guide 14.4.2 Types of DoS Attacks There are four types of DoS attacks: 1 Those that exploit bugs in a TCP/IP implementation. 2 Those that exploit weaknesses in the TCP/IP specification. 3 Brute-force attacks that flood a network with useless data.
Page 183: Figure 75 Three-Way Handshake
ZyAIR G-2000 Plus User’s Guide Figure 75 Three-Way Handshake Under normal circumstances, the application that initiates a session sends a SYN (synchronize) packet to the receiving server. The receiver sends back an ACK (acknowledgment) packet and its own SYN, and then the initiator responds with an ACK (acknowledgment).
Page 184: Figure 76 Syn Flood
ZyAIR G-2000 Plus User’s Guide Figure 76 SYN Flood b In a LAND Attack, hackers flood SYN packets into the network with a spoofed source IP address of the targeted system. This makes it appear as if the host computer sent the packets to itself, making the system unavailable while the target system tries to respond to itself.

ZyAIR G-2000 Plus User’s Guide 14.5 Stateful Inspection With stateful inspection, fields of the packets are compared to packets that are already known to be trusted. For example, if you access some outside service, the proxy server remembers things about your original request, like the port number and source and destination addresses.
Page 187: Stateful Inspection And The Zyair
ZyAIR G-2000 Plus User’s Guide 3 The firewall inspects packets to determine and record information about the state of the packet's connection. This information is recorded in a new state table entry created for the new connection. If there is not a firewall rule for this packet and it is not an attack, then the setting in the Firewall Default Rule screen determines the action for this packet.
Page 188: Tcp Security
ZyAIR G-2000 Plus User’s Guide Below is a brief technical description of how these connections are tracked. Connections may either be defined by the upper protocols (for instance, TCP), or by the ZyAIR itself (as with the "virtual connections" created for UDP and ICMP).
Page 189: Upper Layer Protocols
ZyAIR G-2000 Plus User’s Guide 14.5.5 Upper Layer Protocols Some higher layer protocols (such as FTP and RealAudio) utilize multiple network connections simultaneously. In general terms, they usually have a "control connection" which is used for sending commands between endpoints, and then "data connections" which are used for transmitting bulk information.

IP Classes An IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1.
Page 398: Table 134 Allowed Ip Address Range By Class
ZyAIR G-2000 Plus User’s Guide Since the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B”...

ZyAIR G-2000 Plus User’s Guide 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. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication.
Page 421: Antenna Selection And Positioning Recommendation
ZyAIR G-2000 Plus User’s Guide Appendix K Antenna Selection and Positioning Recommendation An antenna couples RF signals onto air. A transmitter within a wireless device sends an RF signal to the antenna, which propagates the signal through the air. The antenna also operates in reverse by capturing RF signals from the air.
Page 422: Positioning Antennas
ZyAIR G-2000 Plus User’s Guide • Omni-directional antennas send the RF signal out in all directions on a horizontal plane. The coverage area is torus-shaped (like a donut) which makes these antennas ideal for a room environment. With a wide coverage area, it is possible to make circular overlapping coverage areas with multiple access points.
