9 GETTING STARTED Connecting your computer or home network to the gateway is a simple procedure, varying slightly depending on your operating system. The setup is designed to seamlessly integrate the znid with your computer or home network. Moreover, zero-configuration is attained when taking advantage of Universal Plug-and-Play support in Windows XP. The Windows default network settings dictate that in most cases the setup procedure described below will be unnecessary. For example, the default DHCP setting in Windows 2000 is client, requiring no further modification. However, it is advised to follow the setup procedure described below to verify that all communication parameters are valid and that the physical cable connections are correct. znid Setup The basic setup procedure consists of three consecutive configuration stages: 1. Setting up LAN and WAN connections 2. PC network configuration 3. znid configuration Stage 1 - Setting up LAN and WAN Connections LAN Connection Your connection to the Internet is determined by the type of gateway that you have. Please consult the znid Installation Guide for details on how to connect copper wires or fiber to the znid s WAN interface. WAN Connection Your connection to the Internet is determined by the type of gateway that you have. If your gateway has a built-in DSL modem, connect its DSL socket to the wall socket using a telephone cable. Consult your modem documentation regarding specific cables necessary for connection. Mention GPON and AE. znid Administration and Configuation Guide 9

10 Getting Started Stage 2 - PC Network Configuration Each network interface on the PC should either be configured with a statically defined IP address and DNS address, or should be instructed to automatically obtain an IP address using the Network DHCP server. The znid provides a DHCP server on its LAN and it is recommended to configure your LAN to obtain its IP and DNS server IPs automatically. This configuration principle is identical but performed differently on each operating system. The figure below displays the TCP/IP Properties dialog box as it appears in Windows XP. Following are TCP/IP Figure 1: IP and DNS Configuration Windows XP 1. Access Network Connections from the Control Panel. 2. Right-click the Ethernet connection icon, and select Properties. 3.

From the DNS tab, verify that no DNS server is defined in the DNS Service Search Order box and no suffix is defined in the Domain Suffix Search Order box. Linux Additional Network Configuration 1. Login into the system as a super-user, by entering `su at the prompt. 2. Type ifconfig to display the network devices and allocated IP s. 3. Type pump -i <dev>, where <dev> is the network device name. 4. Type ifconfig again to view the new allocated IP address. 5. Make sure no firewall is active on device <dev>. The znid does not require further configuration in order to start working. After the setup described in this chapter, you can immediately start using your gateway to: Share a broadband connection among multiple users (HTTP, FTP, Telnet, NetMeeting) and between all of the computers connected to your home network. znid Administration and Configuation Guide 11

12 Getting Started Build a home network by connecting additional PCs and network devices to the gateway. Control network parameters, including DHCP, DNS and WAN settings. View network status, traffic statistics, system log and more. Allow access from the Internet to games and other services provided by computers in the home net- work. Prohibit computers in the home network from accessing selected services on the Internet. Block access to specific Internet Web sites from your home network. Advanced users can fully configure and control the znid via the Web-based management. Figure 2: Security General Adding Computers to Network Multiple computers can be connected directly to the gateway without requiring a hub or a switch. 12 znid Administration and Configuation Guide

13 WEB-BASED MANAGEMENT Accessing the Web-based Management This chapter describes the znid Web-based management (WBM) which allows you to control various znid system parameters, using a user-friendly graphical interface. The Web-based management includes a connection wizard, a graphic network map, multiple sessions, authentication data kept on gateway, multiple user support, multilingual support, a connection diagnostics screen and more. To access the Web-based management: If your computer is running an operating system that supports UPnP, such Windows XP, you can easily add the computer to your home network and access the Web-based management directly from within. 1. Launch a Web-browser on a PC in the LAN. 2. Type the gateway s IP address or name as provided with your gateway in the address bar (Internet Explorer) or location bar (Netscape Navigator). The default IP address is , and default name is 3. Enter your username and password to log on to the WBM. For security reasons, you should change these settings after the initial login. The default user name is admin, and the default password is zhone for administration rights, and the default user name is user and the default password is password for limited user rights. A read only user is also pre-configured with a user name of user read and a password of password. Your session will automatically time-out after a few minutes of inactivity. If you try to operate the Web- based management after the session has expired the Login screen will appear and you will have to re- enter your user name and password before proceeding. This feature helps to prevent unauthorized users from accessing the web-based management and changing the gateway s settings. Your Home Network Map To view your network map, press the Network Map View button located at the top of the left sidebar of the WBM screen. The Network Map screen will appear. znid Administration and Configuation Guide 13

17 NETWORK CONNECTIONS The znid supports various network connections, both physical and logical. The Network Connections screen enables you to configure the various parameters of your physical connections, the LAN and WAN, and create new connections, using tunneling protocols over existing connections, such as PPP and VPN. When clicking the Network Connections icon on the sidebar for the first time, the following typical screen will appear: Figure 5: Network Connections - Basic Press the Advanced button to expand the screen and display all connection entries. znid Administration and Configuation Guide 17

18 Network Connections Figure 6: Network Connections - Advanced This chapter describes the different network connections available with the znid in their order of appearance in the Network Connections screen, as well as the connection types that you can create using the Connection Wizard. Note: Some of the connections described herein may not be available with certain versions. The znid s default network connections are: LAN - Creating a home/soho network LAN Bridge LAN Ethernet WAN - Internet Connection WAN Ethernet The logical network connections available with the znid are: WAN - Internet Connection Point-to-Point Protocol over Ethernet Ethernet Connection Dynamic Host Configuration Protocol Manual IP Address Configuration Determine Protocol Type Automatically WAN-LAN Bridge Advanced Connections Network Bridging 18 znid Administration and Configuation Guide

19 The Connection Wizard VLAN Interface The Connection Wizard Ethernet Gateway The logical network connections can be easily created using the Connection Wizard. This wizard is consisted of a series of Web-based management screens, intuitively structured to gather all the information needed to create a logical connection. In order to create a connection on an Ethernet gateway using the wizard, click the New Connection link in the Network Connections screen. The Connection Wizard screen will appear. Figure 7: Connection Wizard This screen presents you with the main connection types. Each option that you choose will lead you to further options in a tree-like formation, adding more information with each step and narrowing down the parameters towards the desired network connection. znid Administration and Configuation Guide 19

20 Network Connections Figure 8: Advanced Connection Wizard Screen The tree formation of this section is depicted below. 20 znid Administration and Configuation Guide

21 The Connection Wizard Figure 9: Advanced Connection Wizard Tree Network Types Every network connection in the znid can be configured as one of three types: WAN, LAN or DMZ. This provides high flexibility and increased functionality. For example, you may define that a LAN Ethernet connection on the znid will operate as a WAN network. This means that all hosts in this LAN will be referred to as WAN computers, both by computers outside the znid and by the znid itself. WAN and firewall rules may be applied, such as on any other WAN network. Another example, is that a network connection can be defined as a DMZ (Demilitarized) network. Although the network is physically inside the znid, it will function as an unsecured, independent network, for which the znid merely acts as a router. znid Administration and Configuation Guide 21

22 Network Connections One of these three network types is defined in each connection s configuration screen, in the Network combo-box, as depicted in the following sections. DMZ Network When defining a network connection as a DMZ network, you must also: Remove the connection from under a bridge, if that is the case. Change the connection s routing mode to Route, in the Routing section of the configuration screen. Add a routing rule on your external gateway (which may be with your ISP) informing of the DMZ network behind the znid. LAN Bridge The LAN bridge connection is used to combine several LAN devices under one virtual network. Please note, that when a bridge is removed, its formerly underlying devices inherit the bridge s DHCP settings. For example, the removal of a bridge that is configured as DHCP client, automatically configures the LAN devices formerly constituting the bridge as DHCP clients, with the exact DHCP client configuration. Creation with the Connection Wizard To configure an existing bridge or create a new one, perform the following steps: 1. Click the New Connection link in the Network Connections screen. The Connection Wizard screen will appear. 2. Select the Advanced Connection radio button and click Next. The Advanced Connection screen will appear. 3. Select the Network Bridging radio button and click Next. The Bridge Options screen will appear. 22 znid Administration and Configuation Guide

23 The Connection Wizard Figure 10: Bridge Options 4. Select whether to configure an existing bridge (this option will only appear if a bridge exists) or to add a new one: (a) Configure Existing Bridge Select this option and click Next. The Network Bridging screen will appear allowing you to add new connections or remove existing ones, by checking or unchecking their respective check boxes. znid Administration and Configuation Guide 23

24 Network Connections Figure 11: Network Bridging For example, checking the WAN check box will create a LAN-WAN bridge. (b) Add a New Bridge Select this option and click Next. A different Network Bridging screen will appear allowing you to add a bridge over the unbridged connections, by checking their respective check boxes. Figure 12: Network Bridging 24 znid Administration and Configuation Guide

25 The Connection Wizard Important notes: The same connections cannot be shared by two bridges. A bridge cannot be bridged. Bridged connections will lose their IP settings. 5. Click Next. The Connection Summary screen will appear corresponding to your changes. Figure 13: Connection Summary - Configure Existing Bridge 6. Check the Edit the Newly Created Connection check box if you wish to be routed to the new connection s configuration screen after clicking Finish. 7. Click Finish to save the settings. The new bridge will be added to the network connections list, and will be configurable like any other bridge. General The top part of the configuration window displays general communication parameters. It is recommended not to change the default values in this screen unless you are familiar with the networking concepts they represent. Since your gateway is configured to operate with the default values, no parameter modification is necessary. You can configure the following general connection settings: znid Administration and Configuation Guide 25

26 Network Connections Schedule By default, the connection will always be active. However, you can configure scheduler rules in order to define time segments during which the connection may be active. Once a scheduler rule(s) is defined, this field changes to a combo box, allowing you to choose between the available rules. To learn how to configure scheduler rules. Network Select whether the parameters you are configuring relate to a WAN, LAN or DMZ connection, by selecting the connection type from the combo-box. For more information. Physical Address The physical address of the network card used for your network. Some cards allow you to change this address. MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. The default setting, Manual, allows you to enter the largest packet size that will be transmitted. The recommended size is You should leave this value in the 1200 to 1500 range. To have the gateway select the best MTU for your Internet connection, select Automatic. Figure 14: General Bridge Settings Internet Protocol Select one of the following Internet Protocol options from the Internet Protocol drop down menu: No IP Address Obtain an IP Address Automatically Use the Following IP Address Please note that according to the selection you make in the Internet Protocol drop down menu, the screen will refresh and display relevant configuration settings. No IP Address Select No IP Address if you require that this connection will have no IP address. This can be useful if this connection is under a bridge. 26 znid Administration and Configuation Guide

27 The Connection Wizard Figure 15: Internet Protocol Settings No IP Address Use the Following IP Address The LAN connection is usually configured using a permanent (static) IP address. Your service provider should provide you with this address, and subnet mask. Figure 16: Internet Protocol Settings Static IP Bridge Settings The bridge section allows you to specify the LAN devices that you would like to join under the network bridge. Click the Edit icon on the VLAN column to assign the network connections to specific Virtual LANS. Select the STP check box to enable the Spanning Tree Protocol on the device. You should use this to ensure that there are no loops in your network configuration, and apply these settings in case your network consists of multiple switches, or other bridges apart from those created by the gateway. Figure 17: LAN Bridge Settings znid Administration and Configuation Guide 27

28 Network Connections IP Address Distribution The IP Address Distribution section allows you to configure the gateway s Dynamic Host Configuration Protocol (DHCP) server parameters. The DHCP automatically assigns IP addresses to network PCs. If you enable this feature, make sure that you also configure your network PCs as DHCP clients. Select one of the following options from the IP Address Distribution combo-box: DHCP Server Start IP Address The first IP address that may be assigned to a LAN host. Since the gateway s default IP address is , this address must be or greater. End IP Address The last IP address in the range that can be used to automatically assign IP addresses to LAN hosts. Subnet Mask A mask used to determine to what subnet an IP address belongs. An example of a subnet mask value is Lease Time In Minutes Each device will be assigned an IP address by the DHCP server for a this amount of time, when it connects to the network. When the lease expires the server will determine if the computer has disconnected from the network. If it has, the server may reassign this IP address to a newly-connected computer. This feature ensures that IP addresses that are not in use will become available for other computers on the network. Provide Host Name If Not Specified by Client If the DHCP client does not have a host name, the gateway will automatically assign one. Figure 18: IP Address Distribution DHCP Server DHCP Relay Your gateway can act as a DHCP relay in case you would like to dynamically assign IP addresses from a DHCP server other than your gateway s DHCP server. Note that when selecting this option you must also change the znid s WAN to work in routing mode. 28 znid Administration and Configuation Guide

37 The Connection Wizard General The top part of the configuration window displays general communication parameters. It is recommended not to change the default values in this screen unless you are familiar with the networking concepts they represent. Since your gateway is configured to operate with the default values, no parameter modification is necessary. You can configure the following general connection settings: Schedule By default, the connection will always be active. However, you can configure scheduler rules in order to define time segments during which the connection may be active. Once a scheduler rule(s) is defined, this field changes to a combo box, allowing you to choose between the available rules. Network Select whether the parameters you are configuring relate to a WAN, LAN or DMZ connection, by selecting the connection type from the combo-box. The physical address of the network card used for your network. Some cards allow you to change this address. Clone MAC Allows you to copy the current MAC address of your PC to the MAC address of this device. MTU MTU is the Maximum Transmission Unit. It specifies the largest packet size permitted for Internet transmission. In the default setting, Automatic, the gateway selects the best MTU for your Internet connection. In case you change to manual, you can enter the largest packet size, you should leave this value in the 1200 to 1500 range.

39 The Connection Wizard No IP Address Select No IP Address if you require that your gateway have no IP address. This can be useful if you are working in an environment where you are not connected to other networks, such as the Internet. Figure 35. Internet Protocol Settings No IP Address Obtain an IP Address Automatically Your WAN connection is configured by default to act as a DHCP client. You should keep this configuration in case your service provider supports DHCP, or if you are connecting using a dynamic IP address. The server that assigns the gateway with an IP address, also assigns a subnet mask. You can override the dynamically assigned subnet mask by selecting the Override Subnet Mask and specifying your own mask instead. You can press the Release button to release the current leased IP address. Once the address has been released, the button text changes to Renew. Use the Renew button to renew the leased IP address.

40 Network Connections DNS Server Domain Name System (DNS) is the method by which website or domain names are translated into IP addresses. You can configure the connection to automatically obtain a DNS server address, or specify such an address manually, according to the information provided by your ISP. To configure the connection to automatically obtain a DNS server address, select Obtain DNS Server Address Automatically from the DNS Server drop down menu. Figure 39: Automatic DNS Settings To manually configure DNS server addresses, select Use the Following DNS Server Addresses from the DNS Server drop down menu. Specify up to two different DNS server address, one primary, another secondary. Figure 40: DNS Settings Routing You can choose to setup your gateway to use static or dynamic routing. Dynamic routing automatically adjusts how packets travel on the network, whereas static routing specifies a fixed routing path to neighboring destinations. Routing Select Advanced or Basic routing. Routing Mode Select one of the following routing modes: Route Use route mode if you want your gateway to function as a router between two networks. NAPT Network Address and Port Translation (NAPT) refers to network address translation involving the mapping of port numbers, allowing multiple machines to share a single IP address. Use NAPT if your LAN encompasses multiple devices, a topology that necessitates port translation in addition to address translation. Device Metric The device metric is a value used by the gateway to determine whether one route is superior to another, considering parameters such as bandwidth, delay, and more. 40 znid Administration and Configuation Guide

PPPoE enables your home network PCs that communicate on an Ethernet network to exchange information with PCs on the Internet. PPPoE supports the protocol layers and authentication widely used in PPP and enables a point-to-point connection to be established in the normally multipoint architecture of Ethernet. A discovery process in PPPoE determines the Ethernet MAC address of the remote device in order to establish a session. Creation with the Connection Wizard To create a new PPPoE connection, perform the following steps: 1. Click the New Connection link in the Network Connections screen. The Connection Wizard screen will appear. 2. Select the Internet Connection radio button and click Next. The Internet Connection screen will appear.
