Model names ending in “1”, for example P-660H/HW-D Series, denote a device that works over the analog telephone system, POTS (Plain Old Telephone Service). Model names ending in “3” denote a device that works over ISDN (Integrated Services Digital Network). The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to your ADSL-enabled telephone line. Only use firmware for your ZyXEL Device’s specific model. Refer to the label on the bottom of your ZyXEL Device. The ZyXEL Device is the ideal high-speed Internet access solution. It is compatible with all major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers and supports the ADSL standards as shown in Table 1 on page 34. In addition, the ZyXEL Device with its wireless features allows wireless clients access to your wired network resources and to the Internet. The ZyXEL Device provides protection from attacks by Internet hackers. By default, the firewall blocks all incoming traffic from the WAN. The firewall supports TCP/UDP inspection and DoS (Denial of Services) detection and prevention, as well as real time alerts, reports and logs. A typical Internet access application is shown below P-660HW-Dx v2 User’s Guide 33 Chapter 1 Introducing the ZyXEL Device Figure 1 Protected Internet Access Applications You can also use the ZyXEL Device to connect two geographically dispersed networks over the ADSL line. A typical LAN-to-LAN application example is shown as follows. Figure 2 LAN-to-LAN Application Example The ZyXEL Device is compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable for each standard are shown in the next table. Table 1 ADSL Standards 34 DATA RATE STANDARD UPSTREAM DOWNSTREAM ADSL 832 kbps 8Mbps ADSL2 3.5Mbps 12Mbps ADSL2+ 3.5Mbps 24Mbps If your ZyXEL Device does not support Annex M, the maximum ADSL2/2+ upstream data rate is 1.2 Mbps. ZyXEL Devices which work over ISDN do not support Annex M. The standard your ISP supports determines the maximum upstream and downstream speeds attainable. Actual speeds attained also depend on the distance from your ISP, line quality, etc. P-660HW-Dx v2 User’s Guide Chapter 1 Introducing the ZyXEL Device 1.2 Ways to Manage the ZyXEL Device Use any of the following methods to manage the ZyXEL Device. • Web Configurator. This is recommended for everyday management of the ZyXEL Device using a (supported) web browser. • Command Line Interface. Line commands are mostly used for troubleshooting by service engineers. • FTP for firmware upgrades and configuration backup/restore (Chapter 19 on page 251) • SNMP. The device can be monitored by an SNMP manager. See the SNMP chapter in this User’s Guide. • SPTGEN. SPTGEN is a text configuration file that allows you to configure the device by uploading an SPTGEN file. This is especially convenient if you need to configure many devices of the same type. 1.3 Good Habits for Managing the ZyXEL Device Do the following things regularly to make the ZyXEL Device more secure and to manage the ZyXEL Device more effectively. • Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters. • Write down the password and put it in a safe place. • Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the ZyXEL Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the ZyXEL Device. You could simply restore your last configuration. 1.4 LEDs The following figure shows the ZyXEL Device’s LEDs.

This allows simultaneous Internet access and telephone service on the same line. A splitter also eliminates the destructive interference conditions caused by telephone sets. Install the POTS splitter at the point where the telephone line enters your residence, as shown in the following figure. 36 P-660HW-Dx v2 User’s Guide Chapter 1 Introducing the ZyXEL Device Figure 4 Connecting a POTS Splitter 1 Connect the side labeled “Phone” to your telephone. 2 Connect the side labeled “Modem” or “DSL” to your ZyXEL Device. 3 Connect the side labeled “Line” to the telephone wall jack. 1.5.1.2 Telephone Microfilters Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter, for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice transmissions. The use of a telephone microfilter is optional. 1 Locate and disconnect each telephone. 2 Connect a cable from the wall jack to the “wall side” of the microfilter. 3 Connect the “phone side” of the microfilter to your telephone as shown in the following figure. 4 After you are done, make sure that your telephone works. If your telephone does not work, disconnect the microfilter and contact either your local telephone company or the provider of the microfilter. Figure 5 Connecting a Microfilter You can also use a Y-Connector with a microfilter in order to connect both your modem and a telephone to the same wall jack without using a POTS splitter. 1 Connect a phone cable from the wall jack to the single jack end of the Y-Connector. P-660HW-Dx v2 User’s Guide 37 Chapter 1 Introducing the ZyXEL Device 2 Connect a cable from the double jack end of the Y-Connector to the “wall side” of the microfilter. 3 Connect another cable from the double jack end of the Y-Connector to the ZyXEL Device. 4 Connect the “phone side” of the microfilter to your telephone as shown in the following figure.

P-660HW-Dx v2 User’s Guide 65 Chapter 3 Wizard Setup for Internet Access 66 P-660HW-Dx v2 User’s Guide CHAPTER Bandwidth Management Wizard This chapter shows you how to configure basic bandwidth management using the wizard screens. 4.1 Introduction Bandwidth management allows you to control the amount of bandwidth going out through the ZyXEL Device’s WAN port and prioritize the distribution of the bandwidth according to service bandwidth requirements. This helps keep one service from using all of the available bandwidth and shutting out other users. 4.2 Predefined Media Bandwidth Management Services The following is a description of the services that you can select and to which you can apply media bandwidth management using the wizard screens. Table 17 Media Bandwidth Management Setup: Services SERVICE DESCRIPTION WWW The World Wide Web (WWW) is an Internet system to distribute graphical, hyperlinked information, based on Hyper Text Transfer Protocol (HTTP) - a client/server protocol for the World Wide Web. The Web is not synonymous with the Internet; rather, it is just one service on the Internet. Other services on the Internet include Internet Relay Chat and Newsgroups. The Web is accessed through use of a browser. FTP File Transfer Protocol enables fast transfer of files, including large files that may not be possible by e-mail. FTP uses port number 21. E-Mail Electronic mail consists of messages sent through a computer network to specific groups or individuals. Here are some default ports for e-mail: POP3 - port 110 IMAP - port 143 SMTP - port 25 HTTP - port 80 Telnet Telnet is the login and terminal emulation protocol common on the Internet and in UNIX environments. It operates over TCP/IP networks. Its primary function is to allow users to log into remote host systems. Telnet uses TCP port 23. P-660HW-Dx v2 User’s Guide 67 Chapter 4 Bandwidth Management Wizard Table 17 Media Bandwidth Management Setup: Services (continued) SERVICE DESCRIPTION NetMeeting (H.323) A multimedia communications product from Microsoft that enables groups to teleconference and videoconference over the Internet. NetMeeting supports VoIP, text chat sessions, a whiteboard, file transfers and application sharing. NetMeeting uses H.323. H.323 is a standard teleconferencing protocol suite that provides audio, data and video conferencing. It allows for real-time point-to-point and multipoint communication between client computers over a packet-based network that does not provide a guaranteed quality of service. H.323 is transported primarily over TCP, using the default port number 1720. VoIP (SIP) Sending voice signals over the Internet is called Voice over IP or VoIP. Session Initiated Protocol (SIP) is an internationally recognized standard for implementing VoIP. SIP is an application-layer control (signaling) protocol that handles the setting up, altering and tearing down of voice and multimedia sessions over the Internet. SIP is transported primarily over UDP but can also be transported over TCP, using the default port number 5060. VoIP (H.323) Sending voice signals over the Internet is called Voice over IP or VoIP.

Figure 42 Bandwidth Management Wizard: Complete P-660HW-Dx v2 User’s Guide 71 Chapter 4 Bandwidth Management Wizard 72 P-660HW-Dx v2 User’s Guide P ART III Network WAN Setup (75) LAN Setup (93) Wireless LAN (105) Network Address Translation (NAT) Screens (129) 73 74 CHAPTER WAN Setup This chapter describes how to configure WAN settings. 5.1 WAN Overview A WAN (Wide Area Network) is an outside connection to another network or the Internet. 5.1.1 Encapsulation Be sure to use the encapsulation method required by your ISP. The ZyXEL Device supports the following methods. 5.1.1.1 ENET ENCAP The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the ENET ENCAP Gateway field in the second wizard screen. You can get this information from your ISP. 5.1.1.2 PPP over Ethernet PPPoE (Point-to-Point Protocol over Ethernet) provides access control and billing functionality in a manner similar to dial-up services using PPP. PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, etc.) connection. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example RADIUS). One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the ZyXEL Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ZyXEL Device does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access. P-660HW-Dx v2 User’s Guide 75 Chapter 5 WAN Setup 5.1.1.3 PPPoA PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The ZyXEL Device encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP. 5.1.1.4 RFC 1483 RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to the RFC for more detailed information. 5.1.2 Multiplexing There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP. 5.1.2.1 VC-based Multiplexing In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical. 5.1.2.2 LLC-based Multiplexing In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs. 5.1.3 Encapsulation and Multiplexing Scenarios For Internet access you should use the encapsulation and multiplexing methods used by your ISP. Consult your telephone company for information on encapsulation and multiplexing methods for LAN-to-LAN applications, for example between a branch office and corporate headquarters. There must be prior agreement on encapsulation and multiplexing methods because they cannot be automatically determined. What method(s) you use also depends on how many VCs you have and how many different network protocols you need. The extra overhead that ENET ENCAP encapsulation entails makes it a poor choice in a LAN-to-LAN application. Here are some examples of more suitable combinations in such an application. 5.1.3.1 Scenario 1: One VC, Multiple Protocols PPPoA (RFC-2364) encapsulation with VC-based multiplexing is the best combination because no extra protocol identifying headers are needed. The PPP protocol already contains this information. 76 P-660HW-Dx v2 User’s Guide Chapter 5 WAN Setup 5.1.3.2 Scenario 2: One VC, One Protocol (IP) Selecting RFC-1483 encapsulation with VC-based multiplexing requires the least amount of overhead (0 octets). However, if there is a potential need for multiple protocol support in the future, it may be safer to select PPPoA encapsulation instead of RFC-1483, so you do not need to reconfigure either computer later. 5.1.3.3 Scenario 3: Multiple VCs If you have an equal number (or more) of VCs than the number of protocols, then select RFC1483 encapsulation and VC-based multiplexing. 5.1.4 VPI and VCI Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information. 5.1.5 IP Address Assignment A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP gateway. 5.1.5.1 IP Assignment with PPPoA or PPPoE Encapsulation If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the ENET ENCAP Gateway field. 5.1.5.2 IP Assignment with RFC 1483 Encapsulation In this case the IP Address Assignment must be static with the same requirements for the IP Address and ENET ENCAP Gateway fields as stated above. 5.1.5.3 IP Assignment with ENET ENCAP Encapsulation In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the ZyXEL Device acts as a DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable (N/A) as the DHCP server assigns them to the ZyXEL Device. 5.1.6 Nailed-Up Connection (PPP) A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The ZyXEL Device does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the ZyXEL Device will try to bring up the connection when turned on and whenever the connection is down. A nailed-up connection can be very expensive for obvious reasons. P-660HW-Dx v2 User’s Guide 77 Chapter 5 WAN Setup Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a constant connection and the cost is of no concern 5.1.7 NAT NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network. 5.2 Metric The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number greater than "15" means the link is down. The smaller the number, the lower the "cost". The metric sets the priority for the ZyXEL Device’s routes to the Internet. If any two of the default routes have the same metric, the ZyXEL Device uses the following pre-defined priorities: • Normal route: designated by the ISP (see Section 5.5 on page 80) • Traffic-redirect route (see Section 5.7 on page 89) • WAN-backup route, also called dial-backup (see Section 5.8 on page 89) For example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and dial-backup route has a metric of "3", then the normal route acts as the primary default route. If the normal route fails to connect to the Internet, the ZyXEL Device tries the traffic-redirect route next. In the same manner, the ZyXEL Device uses the dial-backup route if the traffic-redirect route also fails. If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater). IP Policy Routing overrides the default routing behavior and takes priority over all of the routes mentioned above. 5.3 Traffic Shaping Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections. Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed. 78 P-660HW-Dx v2 User’s Guide Chapter 5 WAN Setup Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the maximum average rate at which cells can be sent over the virtual connection. SCR may not be greater than the PCR. Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again. If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that correlates to your upstream line rate. The following figure illustrates the relationship between PCR, SCR and MBS. Figure 43 Example of Traffic Shaping 5.3.1 ATM Traffic Classes These are the basic ATM traffic classes defined by the ATM Forum Traffic Management 4.0 Specification. 5.3.1.1 Constant Bit Rate (CBR) Constant Bit Rate (CBR) provides fixed bandwidth that is always available even if no data is being sent. CBR traffic is generally time-sensitive (doesn't tolerate delay). CBR is used for connections that continuously require a specific amount of bandwidth. A PCR is specified and if traffic exceeds this rate, cells may be dropped. Examples of connections that need CBR would be high-resolution video and voice. 5.3.1.2 Variable Bit Rate (VBR) The Variable Bit Rate (VBR) ATM traffic class is used with bursty connections. Connections that use the Variable Bit Rate (VBR) traffic class can be grouped into real time (VBR-RT) or non-real time (VBR-nRT) connections. The VBR-RT (real-time Variable Bit Rate) type is used with bursty connections that require closely controlled delay and delay variation. It also provides a fixed amount of bandwidth (a PCR is specified) but is only available when data is being sent. An example of an VBR-RT connection would be video conferencing. Video conferencing requires real-time data transfers and the bandwidth requirement varies in proportion to the video image's changing dynamics. P-660HW-Dx v2 User’s Guide 79 Chapter 5 WAN Setup The VBR-nRT (non real-time Variable Bit Rate) type is used with bursty connections that do not require closely controlled delay and delay variation. It is commonly used for "bursty" traffic typical on LANs. PCR and MBS define the burst levels, SCR defines the minimum level. An example of an VBR-nRT connection would be non-time sensitive data file transfers. 5.3.1.3 Unspecified Bit Rate (UBR) The Unspecified Bit Rate (UBR) ATM traffic class is for bursty data transfers. However, UBR doesn't guarantee any bandwidth and only delivers traffic when the network has spare bandwidth. An example application is background file transfer. 5.4 Zero Configuration Internet Access Once you turn on and connect the ZyXEL Device to a telephone jack, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the ZyXEL Device cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting. Zero configuration for Internet access is disable when • the ZyXEL Device is in bridge mode • you set the ZyXEL Device to use a static (fixed) WAN IP address. 5.5 Internet Connection To change your ZyXEL Device’s WAN Internet access settings, click Network > WAN.

P-660HW-Dx v2 User’s Guide Chapter 5 WAN Setup Table 23 More Connections Edit (continued) LABEL DESCRIPTION Multiplexing Select the method of multiplexing used by your ISP from the drop-down list. Choices are VC or LLC. By prior agreement, a protocol is assigned a specific virtual circuit, for example, VC1 will carry IP. If you select VC, specify separate VPI and VCI numbers for each protocol. For LLC-based multiplexing or PPP encapsulation, one VC carries multiple protocols with protocol identifying information being contained in each packet header. In this case, only one set of VPI and VCI numbers need be specified for all protocols. VPI The valid range for the VPI is 0 to 255. Enter the VPI assigned to you. VCI The valid range for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Enter the VCI assigned to you. IP Address This option is available if you select Routing in the Mode field. Obtain an IP Address Automatically Select this if you get a dynamic IP address from your Internet Service Provider (ISP). A dynamic IP address is not fixed; your ISP assigns you a different one each time you connect to the Internet. This option is not available if you select RFC 1483 in the Encapsulation field. Static IP Address Select this if your ISP gave you a fixed IP address. Enter the IP address you were given in the IP Address field. IP Address If your ISP gave you an IP address to use, enter it here. Subnet Mask Enter a subnet mask in dotted decimal notation. Refer to the appendices to calculate a subnet mask If you are implementing subnetting. Gateway IP address Specify a gateway IP address (supplied by your ISP). Connection Nailed-Up Connection Select Nailed-Up Connection when you want your connection up all the time. The ZyXEL Device will try to bring up the connection automatically if it is disconnected. Connect on Demand Select Connect on Demand when you don't want the connection up all the time and specify an idle time-out in the Max Idle Timeout field. Max Idle Timeout Specify an idle time-out in the Max Idle Timeout field when you select Connect on Demand. The default setting is 0, which means the Internet session will not timeout. NAT NAT is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network. None Select None to disable NAT. SUA Only SUA only is available only when you select Routing in the Mode field. Select SUA Only if you have one public IP address and want to use NAT.

P-660HW-Dx v2 User’s Guide Chapter 5 WAN Setup 5.7 Traffic Redirect Traffic redirect forwards traffic to a backup gateway when the ZyXEL Device cannot connect to the Internet. An example is shown in the figure below. Figure 49 Traffic Redirect Example The following network topology allows you to avoid triangle route security issues when the backup gateway is connected to the LAN. Use IP alias to configure the LAN into two or three logical networks with the ZyXEL Device itself as the gateway for each LAN network. Put the protected LAN in one subnet (Subnet 1 in the following figure) and the backup gateway in another subnet (Subnet 2). Configure filters that allow packets from the protected LAN (Subnet 1) to the backup gateway (Subnet 2). Figure 50 Traffic Redirect LAN Setup 5.8 Configuring WAN Backup To change your ZyXEL Device’s WAN backup settings, click Network > WAN > WAN Backup Setup. The screen appears as shown. P-660HW-Dx v2 User’s Guide 89 Chapter 5 WAN Setup Figure 51 WAN Backup Setup The following table describes the labels in this screen. Table 25 WAN Backup Setup LABEL DESCRIPTION WAN Backup Setup Backup Type Select the method that the ZyXEL Device uses to check the DSL connection. Select DSL Link to have the ZyXEL Device check if the connection to the DSLAM is up. Select ICMP to have the ZyXEL Device periodically ping the IP addresses configured in the Check WAN IP Address fields. Check WAN IP Address1-3 Configure this field to test your ZyXEL Device's WAN accessibility. Type the IP address of a reliable nearby computer (for example, your ISP's DNS server address). Note: If you activate either traffic redirect or dial backup, you must configure at least one IP address here. When using a WAN backup connection, the ZyXEL Device periodically pings the addresses configured here and uses the other WAN backup connection (if configured) if there is no response. 90 Fail Tolerance Type the number of times (2 recommended) that your ZyXEL Device may ping the IP addresses configured in the Check WAN IP Address field without getting a response before switching to a WAN backup connection (or a different WAN backup connection). Recovery Interval When the ZyXEL Device is using a lower priority connection (usually a WAN backup connection), it periodically checks to whether or not it can use a higher priority connection. Type the number of seconds (30 recommended) for the ZyXEL Device to wait between checks. Allow more time if your destination IP address handles lots of traffic. P-660HW-Dx v2 User’s Guide Chapter 5 WAN Setup Table 25 WAN Backup Setup (continued) LABEL DESCRIPTION Timeout Type the number of seconds (3 recommended) for your ZyXEL Device to wait for a ping response from one of the IP addresses in the Check WAN IP Address field before timing out the request. The WAN connection is considered "down" after the ZyXEL Device times out the number of times specified in the Fail Tolerance field. Use a higher value in this field if your network is busy or congested. Traffic Redirect Traffic redirect forwards traffic to a backup gateway when the ZyXEL Device cannot connect to the Internet. Active Traffic Redirect Select this check box to have the ZyXEL Device use traffic redirect if the normal WAN connection goes down. Note: If you activate traffic redirect, you must configure at least one Check WAN IP Address. Metric This field sets this route's priority among the routes the ZyXEL Device uses. The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number greater than "15" means the link is down. The smaller the number, the lower the "cost". Backup Gateway Type the IP address of your backup gateway in dotted decimal notation. The ZyXEL Device automatically forwards traffic to this IP address if the ZyXEL Device's Internet connection terminates. Apply Click Apply to save the changes.

P-660HW-Dx v2 User’s Guide 91 Chapter 5 WAN Setup 92 P-660HW-Dx v2 User’s Guide CHAPTER LAN Setup This chapter describes how to configure LAN settings. 6.1 LAN Overview A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses. See Section 6.3 on page 98 to configure the LAN screens. 6.1.1 LANs, WANs and the ZyXEL Device The actual physical connection determines whether the ZyXEL Device ports are LAN or WAN ports. There are two separate IP networks, one inside the LAN network and the other outside the WAN network as shown next. Figure 52 LAN and WAN IP Addresses P-660HW-Dx v2 User’s Guide 93 Chapter 6 LAN Setup 6.1.2 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 you turn DHCP service off, you must have another DHCP server on your LAN, or else the computer must be manually configured. 6.1.2.1 IP Pool Setup The ZyXEL Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your LAN computers. 6.1.3 DNS Server Address DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask. There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If your ISP gives you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup, otherwise, leave them blank. Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The ZyXEL Device supports the IPCP DNS server extensions through the DNS proxy feature. If the Primary and Secondary DNS Server fields in the DHCP Setup screen are not specified, for instance, left as 0.0.0.0, the ZyXEL Device tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the ZyXEL Device, the ZyXEL Device forwards the query to the real DNS server learned through IPCP and relays the response back to the computer. 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 DHCP 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 Device’s intervention. 6.1.4 DNS Server Address Assignment Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. There are two ways that an ISP disseminates the DNS server addresses. 94 P-660HW-Dx v2 User’s Guide Chapter 6 LAN Setup • The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the DHCP Setup screen. • The ZyXEL Device acts as a DNS proxy when the Primary and Secondary DNS Server fields are left as 0.0.0.0 in the DHCP Setup screen. 6.2 LAN TCP/IP The ZyXEL Device has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. 6.2.1 IP Address and Subnet Mask Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number. Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the ZyXEL Device. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network. Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your ZyXEL Device, but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your ZyXEL Device will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the ZyXEL Device unless you are instructed to do otherwise. 6.2.1.1 Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet, for example, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks: • 10.0.0.0 — 10.255.255.255 • 172.16.0.0 — 172.31.255.255 • 192.168.0.0 — 192.168.255.255 P-660HW-Dx v2 User’s Guide 95 Chapter 6 LAN Setup You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses. Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space. 6.2.2 RIP Setup RIP (Routing Information Protocol) allows a router to exchange routing information with other routers. The RIP Direction field controls the sending and receiving of RIP packets. When set to: • Both - the ZyXEL Device will broadcast its routing table periodically and incorporate the RIP information that it receives. • In Only - the ZyXEL Device will not send any RIP packets but will accept all RIP packets received. • Out Only - the ZyXEL Device will send out RIP packets but will not accept any RIP packets received. • None - the ZyXEL Device will not send any RIP packets and will ignore any RIP packets received. The Version field controls the format and the broadcasting method of the RIP packets that the ZyXEL Device sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting. 6.2.3 Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. 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. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address 96 P-660HW-Dx v2 User’s Guide Chapter 6 LAN Setup 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group. 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. 6.2.4 Any IP Traditionally, you must set the IP addresses and the subnet masks of a computer and the ZyXEL Device to be in the same subnet to allow the computer to access the Internet (through the ZyXEL Device). In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the ZyXEL Device. With the Any IP feature and NAT enabled, the ZyXEL Device allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply connect the computer to the ZyXEL Device and access the Internet. The following figure depicts a scenario where a computer is set to use a static private IP address in the corporate environment. In a residential house where a ZyXEL Device is installed, you can still use the computer to access the Internet without changing the network settings, even when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. Figure 53 Any IP Example The Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that is in the same subnet as the ZyXEL Device’s IP address. P-660HW-Dx v2 User’s Guide 97 Chapter 6 LAN Setup You must enable NAT/SUA to use the Any IP feature on the ZyXEL Device. 6.2.4.1 How Any IP Works Address Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network. IP routing table is defined on IP Ethernet devices (the ZyXEL Device) to decide which hop to use, to help forward data along to its specified destination. The following lists out the steps taken, when a computer tries to access the Internet for the first time through the ZyXEL Device. 1 When a computer (which is in a different subnet) first attempts to access the Internet, it sends packets to its default gateway (which is not the ZyXEL Device) by looking at the MAC address in its ARP table. 2 When the computer cannot locate the default gateway, an ARP request is broadcast on the LAN. 3 The ZyXEL Device receives the ARP request and replies to the computer with its own MAC address. 4 The computer updates the MAC address for the default gateway to the ARP table. Once the ARP table is updated, the computer is able to access the Internet through the ZyXEL Device. 5 When the ZyXEL Device receives packets from the computer, it creates an entry in the IP routing table so it can properly forward packets intended for the computer. After all the routing information is updated, the computer can access the ZyXEL Device and the Internet as if it is in the same subnet as the ZyXEL Device. 6.3 Configuring LAN IP Click LAN to open the IP screen.

This allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, even when the IP addresses of the computer and the ZyXEL Device are not in the same subnet. When you disable the Any IP feature, only computers with dynamic IP addresses or static IP addresses in the same subnet as the ZyXEL Device’s LAN IP address can connect to the ZyXEL Device or access the Internet through the ZyXEL Device. Windows Networking (NetBIOS over TCP/IP) NetBIOS (Network Basic Input/Output System) are TCP or UDP packets that enable a computer to connect to and communicate with a LAN. For some dial-up services such as PPPoE or PPTP, NetBIOS packets cause unwanted calls. However it may sometimes be necessary to allow NetBIOS packets to pass through to the WAN in order to find a computer on the WAN. Allow between LAN and WAN Select this check box to forward NetBIOS packets from the LAN to the WAN and from the WAN to the LAN. If your firewall is enabled with the default policy set to block WAN to LAN traffic, you also need to enable the default WAN to LAN firewall rule that forwards NetBIOS traffic. Clear this check box to block all NetBIOS packets going from the LAN to the WAN and from the WAN to the LAN. Back Click Back to return to the previous screen. Apply Click Apply to save the changes.
