CHAPTER 7 Wireless LAN This chapter discusses how to configure the wireless network settings in your ZyXEL Device. See the appendices for more detailed information about wireless networks. 7.1 Wireless Network Overview The following figure provides an example of a wireless network. Figure 50 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients.
Chapter 7 Wireless LAN Every wireless client in the same wireless network must use security compatible with the AP. Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network. 7.2 Wireless Security Overview The following sections introduce different types of wireless security you can set up in the wireless network. 7.2.1 SSID Normally, the AP acts like a beacon and regularly broadcasts the SSID in the area.
Chapter 7 Wireless LAN If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users. Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.
Chapter 7 Wireless LAN When you select WPA2 or WPA2-PSK in your ZyXEL Device, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPA Compatible option in the ZyXEL Device. Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption.
Chapter 7 Wireless LAN The following table describes the general wireless LAN labels in this screen. Table 24 Network > Wireless LAN > General LABEL DESCRIPTION Enable Wireless LAN Click the check box to activate wireless LAN. Name(SSID) (Service Set IDentity) The SSID identifies the Service Set with which a wireless station is associated. Wireless stations associating to the access point (AP) must have the same SSID.
Chapter 7 Wireless LAN The following table describes the labels in this screen. Table 25 Wireless No Security LABEL DESCRIPTION Security Mode Choose No Security from the drop-down list box. Apply Click Apply to save your changes back to the ZyXEL Device. Reset Click Reset to reload the previous configuration for this screen. 7.3.2 WEP Encryption WEP encryption scrambles the data transmitted between the wireless stations and the access points to keep network communications private.
Chapter 7 Wireless LAN The following table describes the wireless LAN security labels in this screen. Table 26 Network > Wireless LAN > General: Static WEP LABEL DESCRIPTION Passphrase Enter a passphrase (password phrase) of up to 32 printable characters and click Generate.

CHAPTER 8 WAN Setup This chapter describes how to configure WAN settings. 8.1 WAN Overview A WAN (Wide Area Network) is an outside connection to another network or the Internet. Your ZyXEL Device uses the IEEE 802.16e WiMAX standard to connect wirelessly to a WiMAX base station (see Section 1.1 on page 33). 8.2 WiMAX WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.
Chapter 8 WAN Setup Figure 66 WiMAX: Multiple Mobile Stations A base station's coverage area can extend over many hundreds of meters, even under poor conditions. A base station provides network access to subscriber stations and mobile stations, and communicates with other base stations. The radio frequency and bandwidth of the link between the ZyXEL Device and the base station are controlled by the base station. The ZyXEL Device follows the base stations configuration. 8.2.
Chapter 8 WAN Setup Not all ZyXEL Device models have all the fields shown here. Figure 68 Network > WAN > Internet Connection The following table describes the labels in this screen. Table 32 Network > WAN > Internet Connection LABEL DESCRIPTION ISP Parameters for Internet Access User Use this field to enter the username associated with your Internet access account. You can enter up to 61 printable ASCII characters.

PKM provides security between the ZyXEL Device and the base station. At the time of writing, the ZyXEL Device supports PKMv2 only. See the WiMAX security appendix for more information. Authentication This field displays the user authentication method.
Chapter 8 WAN Setup 8.4 Frequency Settings In a WiMAX network, a mobile or subscriber station must use a radio frequency supported by the base station to communicate. When the ZyXEL Device looks for a connection to a base station, it can search a range of frequencies. Radio frequency is measured in Hertz (Hz). Table 33 Radio Frequency Conversion 1 kHz = 1000 Hz 1 MHz = 1000 kHz (1000000 Hz) 1 GHz = 1000 MHz (1000000 kHz) 8.4.
Chapter 8 WAN Setup Use the WiMAX Frequency screen to define the radio frequencies to be searched for available wireless connections. See Section 8.4.2.1 on page 113 for an example of using the WiMAX Frequency screen. It may take several minutes for the ZyXEL Device to find a connection. The ZyXEL Device searches the DL Frequency settings in ascending numerical order, from [0] to [9]. If you enter a 0 in a DL Frequency field, the ZyXEL Device immediately moves on to the next DL Frequency field.
Chapter 8 WAN Setup Figure 70 Network > WAN >WiMAX Frequency The following table describes the labels in this screen. Table 35 Network > WAN > WiMAX Frequency LABEL DESCRIPTION DL Frequency [0] ~ [9] These fields show the downlink frequency settings in kilohertz (kHz).

CHAPTER 9 LAN Use these screens to set up the ZyXEL Device on the LAN. You can configure its IP address and subnet mask, DHCP services, and other subnets. You can also control how the ZyXEL Device sends routing information using RIP. 9.1 LAN Overview A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is usually a computer network limited to the immediate area, such as the same building or floor of a building. 9.1.
Chapter 9 LAN 9.1.2 DHCP Setup DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the ZyXEL Device as a DHCP server or disable it. When configured as a server, the ZyXEL Device provides the TCP/IP configuration for the clients. If DHCP service is disabled, you must have another DHCP server on your LAN, or else each computer must be manually configured.
Chapter 9 LAN Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the LAN Setup screen. This way, the ZyXEL Device can pass the DNS servers to the computers and the computers can query the DNS server directly without the ZyXEL Devices intervention. 9.1.
Chapter 9 LAN The ZyXEL Device supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMPv2). At start up, the ZyXEL Device queries all directly connected networks to gather group membership. After that, the ZyXEL Device periodically updates this information. IP multicasting can be enabled/disabled on the ZyXEL Device LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces. 9.2 LAN Screens 9.2.

CHAPTER 10 NAT Use these screens to configure port forwarding and trigger ports for the ZyXEL Device. You can also enable and disable SIP, FTP, and H.323 ALG. 10.1 NAT Overview 10.1.1 Port Forwarding: Services and Port Numbers A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.
Chapter 10 NAT 10.1.2 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address.
Chapter 10 NAT 2 If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN cant trigger it. 10.1.3 SIP ALG Some applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because they embed IP addresses and port numbers in their packets data payload. Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.

CHAPTER 11 VPN Transport 11.1 Overview This chapter describes the Network > VPN Transport screens. The ZyXEL Devices VPN Transport feature allows traffic from multiple users to pass through the WiMAX network, to the service providers router. Each user has his own personal connection to the service provider, even though there is only a single WiMAX connection. This allows the service provider to identify which user traffic comes from.
Chapter 11 VPN Transport 11.1.1 What You Can Do in the VPN Transport Screens Use the Network > VPN Transport > General screen (see Section 11.2 on page 140) to turn VPN transport on or off, and to set the VPN transport endpoint (your service providers router). Use the Network > VPN Transport > Customer Interface screen (see Section 11.3 on page 141) to specify which users can use which WiMAX network links. Use the Network > VPN Transport > Ethernet Pseudowire screen (see Section 11.
Chapter 11 VPN Transport Ethernet Pseudowires Because VPLS mimics a simple wired Ethernet connection to your service providers router, the connection between the ZyXEL Device and the peer device is known as an Ethernet pseudowire or PW. The Ethernet pseudowires use MPLS (MultiProtocol Label Switching) virtual circuit labels to define the connection. In any such pseudowire, the ingress label on one device must be the same as the egress label on the peer device, as shown in the following figure.
Chapter 11 VPN Transport The ZyXEL Device has a default customer interface configured for frames that arrive at the ZyXEL Device without VLAN tags. 11.1.3 Before You Begin Before you start configuring your ZyXEL Device to use VPN transport, ensure that you have the following from the service provider. The IP address or domain name of the service providers edge router. Virtual circuit (VC) labels for each Ethernet Pseudowire you want to create.
Chapter 11 VPN Transport 11.3 The Customer Interface Screen Use this screen to configure the VPNs used by the ZyXEL Device. The customer interfaces connect data coming from your computers to Ethernet pseudowires, according to the datas VLAN (Virtual Local Area Network) information. One customer interface is for traffic that has no tag; this is the default interface (rule 0) which cannot be deleted in the GUI. All other customer interfaces are identified by their VLAN ID.
Chapter 11 VPN Transport Table 52 Network > VPN Transport > Customer Interface LABEL DESCRIPTION VLAN ID For a tagged interface, this displays the IEEE 802.1Q VLAN ID number. For the untagged interface, -1 displays. Mode (B, R) This displays either B (bridging) or R (routing). Only the default interface, interface 0, can be a routing interface.
Chapter 11 VPN Transport Table 53 Network > VPN Transport > Customer Interface Edit LABEL DESCRIPTION VLAN ID Enter the Virtual Local Area Network Identifier number (1 ~ 4094) for this interface. This VLAN ID must not be used by any other customer interface. For the untagged interface, -1 displays. Mode This displays Bridging or Routing. A tagged interface can operate in bridging mode only.

Chapter 11 VPN Transport Each LSP has a defined start-point and end-point. Since MPLS creates mono-directional paths (traffic flows in only one direction), each Ethernet pseudowire uses two LSPs so that traffic can flow both ways. One LSP carries upstream traffic, and the other carries downstream traffic. 11.8.2 Generic Routing Encapsulation In order to transport the VPLS traffic over the WiMAX network, the ZyXEL Device uses the Generic Routing Encapsulation (GRE) protocol.

CHAPTER 12 SIP Use these screens to set up your SIP accounts and to configure QoS settings. 12.1 SIP Overview 12.1.1 Introduction to VoIP VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows you to make phone calls and send faxes over the Internet at a fraction of the cost of using the traditional circuit-switched telephone network. You can also use servers to run telephone service applications like PBX services and voice mail.
Chapter 12 SIP 12.1.3.2 SIP Service Domain The SIP service domain of the VoIP service provider (the company that lets you make phone calls over the Internet) is the domain name in a SIP URI. For example, if the SIP address is 1122334455@VoIP-provider.com, then VoIP-provider.com is the SIP service domain. 12.1.4 SIP Call Progression The following figure displays the basic steps in the setup and tear down of a SIP call. A calls B. Table 57 SIP Call Progression A B 1. INVITE 2. Ringing 3. OK 4. ACK 5.
