MAX-207HW2R User’s Guide 19CHAPTER  1 Getting Started1.1  About Your MAX-207HW2R The MAX-207HW2R has a built-in switch and one phone port. It allows you to access the Internet by connecting to a WiMAX wireless network. You can use a traditional analog telephone to make Internet calls using the MAX-207HW2R’s Voice over IP (VoIP) communication capabilities. You can configure firewall and content filtering as well as a host of other features. The web browser-based Graphical User Interface (GUI), also known as the web configurator, provides easy management.See Chapter 20 on page 173 for a complete list of features for your model.1.1.1  WiMAX Internet AccessConnect your computer or network to the MAX-207HW2R for WiMAX Internet access. See the Quick Start Guide for instructions on hardware connection.In a wireless metropolitan area network (MAN), the MAX-207HW2R connects to a WiMAX base station (BS) for Internet access. The following diagram shows a notebook computer equipped with the MAX-207HW2R connecting to the Internet through a WiMAX base station (marked BS).Figure 1   Mobile Station and Base StationWhen the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network.
Chapter 1 Getting StartedMAX-207HW2R User’s Guide20Use content filtering to block access to web sites with URLs containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.1.1.2  Make Calls via Internet Telephony Service ProviderIn a home or small office environment, you can use the MAX-207HW2R to make and receive the following types of VoIP telephone calls:• Peer-to-Peer calls - Use the MAX-207HW2R to make a call directly to the recipient’s IP address without using a SIP proxy server.Figure 2   MAX-207HW2R’s VoIP Features - Peer-to-Peer Calls• Calls via a VoIP service provider - The MAX-207HW2R sends your call to a VoIP service provider’s SIP server which forwards your calls to either VoIP or PSTN phones.Figure 3   MAX-207HW2R’s VoIP Features - Calls via VoIP Service Provider

Chapter 1 Getting StartedMAX-207HW2R User’s Guide221.3  Good Habits for Managing the MAX-207HW2RDo the following things regularly to make the MAX-207HW2R more secure and to manage the MAX-207HW2R 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 MAX-207HW2R becomes unstable or even crashes. If you forget your password, you will have to reset the MAX-207HW2R to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the MAX-207HW2R. You could simply restore your last configuration.Signal Strength IndicatorThe Strength Indicator LEDs display the Interference-plus-Noise Ratio (CINR) of the wireless (WiMAX) connection.Signal 1 On The signal strength is in the range between 5 and 15.Signal 2 On The signal strength is in the range between 16 and 24.Signal 3 On The signal strength is greater than or equal to 25 dBmVoice Off No SIP account is registered, or the MAX-207HW2R is not receiving power.Green A SIP account is registered.Green (Blinking) A SIP account is registered, and the phone attached to the LINE port is in use (off the hook).Yellow A SIP account is registered and has a voice message on the SIP server.Yellow (Blinking) A SIP account is registered and has a voice message on the SIP server, and the phone attached to the LINE port is in use (off the hook).WLAN Off The Wi-Fi network is not operational.Green The Wi-Fi network is operational.Blinking Green The WiMAX Device is sending and receiving data across the Wi-Fi network.Table 2   The MAX-207HW2RLED STATE DESCRIPTION

A LAN, as its name implies, is limited to a local area such as a home or office environment. LANs have different topologies, the most common being the linear bus and the star configuration.IP AddressIP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet MaskThe subnet mask specifies the network number portion of an IP address. Your device will compute the subnet mask automatically based on the IP Address that
Chapter 3 The Setup ScreensMAX-207HW2R User’s Guide32you entered. You do not need to change the computer subnet mask unless you are instructed to do so.DHCPYour WiMAX Modem can act as a DHCP (Dynamic Host Configuration Protocol) server that can assign your LAN computers an IP address, subnet mask, DNS and other routing information when its LAN DHCP feature is turned on.DaytimeA network protocol used by devices for debugging and time measurement. A computer can use this protocol to set its internal clock but only if it knows in which order the year, month, and day are returned by the server. Not all servers use the same format.TimeA network protocol for retrieving the current time from a server. The computer issuing the command compares the time on its clock to the information returned by the server, adjusts itself automatically for time zone differences, then calculates the difference and corrects itself if there has been any temporal drift.NTPNTP stands for Network Time Protocol. It is employed by devices connected to the Internet in order to obtain a precise time setting from an official time server. These time servers are accurate to within 200 microseconds.3.1.3  Before You Begin• Make sure that you have made all the appropriate hardware connections to the MAX-207HW2R, as described in the Quick Start Guide.• Make sure that you have logged in to the web configurator at least one time and changed your password from the default, as described in the Quick Start Guide.3.2  LAN ConfigurationClick the SETUP icon in the navigation bar to set up the MAX-207HW2R’s IP address and subnet mask.

Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.
Chapter 5 The LAN Configuration ScreensMAX-207HW2R User’s Guide44Subnet MasksSubnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.DNSDNS (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 networking device before you can access it.DHCPA DHCP (Dynamic Host Configuration Protocol) server can assign your MAX-207HW2R an IP address, subnet mask, DNS and other routing information when it’s turned on.5.2  DHCP SetupClick ADVANCED > LAN Configuration > DHCP Setup to enable, disable, and configure the DHCP server in the MAX-207HW2R.Figure 12   ADVANCED > LAN Configuration > DHCP Setup

Chapter 5 The LAN Configuration ScreensMAX-207HW2R User’s Guide505.6  Technical ReferenceThe following section contains additional technical information about the MAX-207HW2R features described in this chapter.5.6.1  IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, 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 MAX-207HW2R. 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 192.168.100.1 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.Multicast You do not have to enable multicasting to use RIP-2M. (See RIP Version.)Select which version of IGMP the MAX-207HW2R uses to support multicasting on the LAN. Multicasting sends packets to some computers on the LAN and is an alternative to unicasting (sending packets to one computer) and broadcasting (sending packets to every computer).•None - The MAX-207HW2R does not support multicasting.•IGMP-v1 - The MAX-207HW2R supports IGMP version 1.•IGMP-v2 - The MAX-207HW2R supports IGMP version 2.Multicasting can improve overall network performance. However, it requires extra processing and generates more network traffic. In addition, other computers on the LAN have to support the same version of IGMP.Apply Click to save your changes.Reset Click to restore your previously saved settings.Table 13   ADVANCED > LAN Configuration > Advanced (continued)LABEL DESCRIPTION
 Chapter 5 The LAN Configuration ScreensMAX-207HW2R User’s Guide 51Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.100.1, for your MAX-207HW2R, 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 MAX-207HW2R 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 MAX-207HW2R unless you are instructed to do otherwise.5.6.2  DHCP SetupDHCP (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 MAX-207HW2R as a DHCP server or disable it. When configured as a server, the MAX-207HW2R 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.The MAX-207HW2R 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.These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 5.3 on page 45.5.6.3  LAN TCP/IPThe MAX-207HW2R has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.The LAN parameters of the MAX-207HW2R are preset in the factory with the following values:• IP address of 192.168.100.1 with subnet mask of 255.255.255.0 (24 bits)• DHCP server enabled with 32 client IP addresses starting from 192.168.1.33. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), see Section 5.3 on page 45.5.6.4  DNS Server AddressDNS (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.
Chapter 5 The LAN Configuration ScreensMAX-207HW2R User’s Guide52The 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 ISPs 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 MAX-207HW2R supports the IPCP DNS server extensions through the DNS proxy feature.If the Primary and Secondary DNS Server fields in the LAN Setup screen are not specified, for instance, left as 0.0.0.0, the MAX-207HW2R tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the MAX-207HW2R, the MAX-207HW2R 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 LAN Setup screen. This way, the MAX-207HW2R can pass the DNS servers to the computers and the computers can query the DNS server directly without the MAX-207HW2R’s intervention.5.6.5  RIP SetupRIP (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 MAX-207HW2R will broadcast its routing table periodically and incorporate the RIP information that it receives.•In Only - the MAX-207HW2R will not send any RIP packets but will accept all RIP packets received.•Out Only - the MAX-207HW2R will send out RIP packets but will not accept any RIP packets received.•None - the MAX-207HW2R 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 MAX-207HW2R sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information.
 Chapter 5 The LAN Configuration ScreensMAX-207HW2R User’s Guide 53RIP-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.5.6.6  MulticastTraditionally, 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 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 MAX-207HW2R supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the MAX-207HW2R queries all directly connected networks to gather group membership. After that, the MAX-207HW2R periodically updates this information. IP multicasting can be enabled/disabled on the MAX-207HW2R LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.

For example, you may just want to set up a network name, a wireless radio channel and some security in the General screen.6.1.2  What You Need to Know About WIFIWireless Basics• Every device in the same wireless network must use the same Service Set IDentity (SSID).The SSID is the name of the wireless network.• If two wireless networks overlap, they should use different channels.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.Wireless Network ConstructionWireless networks consist of wireless clients, access points and bridges. • A wireless client is a radio connected to a user’s computer. • An access point is a radio with a wired connection to a network, which can connect with numerous wireless clients and let them access the network. • A bridge is a radio that relays communications between access points and wireless clients, extending a network’s range. Traditionally, a wireless network operates in one of two ways.• An “infrastructure” type of network has one or more access points and one or more wireless clients.  The wireless clients connect to the access points.• An “ad-hoc” type of network is one in which there is no access point. Wireless clients connect to one another in order to exchange information.Wired Equivalent Privacy (WEP)WEP (Wired Equivalent Privacy) encrypts data transmitted between wired and wireless networks to keep the transmission private. Although one of the original wireless encryption protocols, WEP is also the weakest. Many people use it strictly to deter unintentional usage of their wireless network by outsiders.
 Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide 57Authentication Type The IEEE 802.11b/g standard describes a simple authentication method between the wireless stations and AP. Three authentication types are defined: Auto, Open and Shared. The MAX-207HW2R supports the WEP (Open) and WEP (Shared) authentication types.• Open mode is implemented for ease-of-use and when security is not an issue. The wireless station and the AP or peer computer do not share a secret key. Thus the wireless stations can associate with any AP or peer computer and listen to any transmitted data that is not encrypted.• Shared mode involves a shared secret key to authenticate the wireless station to the AP or peer computer. This requires you to enable the wireless LAN security and use same settings on both the wireless station and the AP or peer computer.Wi-Fi Protected Access (WPA)WPA encrypts data transmitted between wired and wireless networks to keep the transmission private. It affords vastly stronger security than its lower-tier counterpart, WEP (Wired Equivalent Privacy). It comes in two different flavors: WPA and WPA2. Always try to use WPA2 as it implements the full version of the security standard while WPA does not.WPA2 WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. It includes two data encryption algorithms, Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication Code Protocol (CCMP). WPA2 reduces the number of key exchange messages from six to four (CCMP 4-way handshake) and shortens the time required to connect to a network. Other WPA2 authentication features that are different from WPA include key caching and pre-authentication. These two features are optional and may not be implemented in all wireless devices. See also WPA.Pre-Shared Key (PSK)A pre-shared key is a password shared between the server and the client that unlocks the algorithm used to encrypt the data traffic between them. Without the proper password, the client and the server cannot communicate.
Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide58SecuritySecurity stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.Use the strongest security that every wireless client in the wireless network supports.Note: WPA2 or WPA2-PSK security is recommended.• WPA2-PSK and WPA-PSK do not employ user authentication and are known as the personal version of WPA.• WEP is better than no security, but it is still possible for unauthorized devices to figure out the original information pretty quickly.MAC FilterEvery Ethernet device has a unique MAC (Media Access Control) address. The MAC address consists of twelve hexadecimal characters (0-9, and A to F), and it is usually written in the following format: “0A:A0:00:BB:CC:DD”. The MAC filter controls access to the wireless network. You can use the MAC address of each wireless client to allow or deny access to the wireless network.Finding Out More• See Section 6.5 on page 66 for advanced technical information on wireless networks.Table 14   Wireless Security LevelsSECURITY LEVEL SECURITY TYPEWeakest  StrongestNo SecurityMAC FilterWEP EncryptionIEEE 802.1x EAP with RADIUS Server AuthenticationWPA-PSK (Wi-Fi Protected Access Pre-Shared Key)WPA (Wi-Fi Protected Access)WPA-PSK2WPA2
 Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide 596.1.3  Before You StartBefore you start using these screens, ask yourself the following questions. See Section 6.1.2 on page 56 if some of the terms used here do not make sense to you.• What wireless standards do the other wireless devices support (IEEE 802.11g, for example)? What is the most appropriate standard to use?• What security options do the other wireless devices support (WPA-PSK, for example)? What is the best one to use?• Do the other wireless devices support WPS (Wi-Fi Protected Setup)? If so, you can set up a well-secured network very easily. Even if some of your devices support WPS and some do not, you can use WPS to set up your network and then add the non-WPS devices manually, although this is somewhat more complicated to do.6.2  General Screen Note: If you are configuring the MAX-207HW2R from a computer connected to the wireless LAN and you change the MAX-207HW2R’s SSID or security settings, you will lose your wireless connection when you press Apply to confirm.

Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide666.5  Wireless LAN Technical ReferenceThis section discusses wireless LANs in depth. For more information, see the appendix.6.5.1  Additional Wireless TermsThe following table describes some wireless network terms and acronyms used in the MAX-207HW2R’s Web Configurator.6.5.2  Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.6.5.2.1  Network Name (SSID)Normally, the MAX-207HW2R acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the MAX-207HW2R does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.This type of security is fairly weak, however, because there are ways for unauthorized wireless devices to get the SSID. In addition, unauthorized wireless devices can still see the information that is sent in the wireless network.Table 21   Additional Wireless TermsTERM DESCRIPTIONRTS/CTS Threshold In a wireless network which covers a large area, wireless devices are sometimes not aware of each other’s presence.  This may cause them to send information to the AP at the same time and result in information colliding and not getting through.By setting this value lower than the default value, the wireless devices must sometimes get permission to send information to the MAX-207HW2R. The lower the value, the more often the devices must get permission.If this value is greater than the fragmentation threshold value (see below), then wireless devices never have to get permission to send information to the MAX-207HW2R.Preamble A preamble affects the timing in your wireless network. There are two preamble modes: long and short. If a device uses a different preamble mode than the MAX-207HW2R does, it cannot communicate with the MAX-207HW2R.Fragmentation Threshold A small fragmentation threshold is recommended for busy networks, while a larger threshold provides faster performance if the network is not very busy.
 Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide 676.5.2.2  MAC FilterEvery device that can use a wireless network has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each device in the wireless network, see the device’s User’s Guide or other documentation.You can use the MAC address filter to tell the MAX-207HW2R which devices are allowed or not allowed to use the wireless network. If a device is allowed to use the wireless network, it still has to have the correct information (SSID, channel, and security). If a device is not allowed to use the wireless network, it does not matter if it has the correct information.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized wireless devices to get the MAC address of an authorized device. Then, they can use that MAC address to use the wireless network.6.5.2.3  User AuthenticationAuthentication is the process of verifying whether a wireless device is allowed to use the wireless network. You can make every user log in to the wireless network before they can use it. However, every device in the wireless network has to support IEEE 802.1x to do this.For wireless networks, you can store the user names and passwords for each user in a RADIUS server. This is a server used in businesses more than in homes. If you do not have a RADIUS server, you cannot set up user names and passwords for your users.Unauthorized wireless 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.6.5.2.4  EncryptionWireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide68The types of encryption you can choose depend on the type of authentication. (See Section 6.5.2.3 on page 67 for information about this.)For example, if the wireless network has a RADIUS server, you can choose WPA or WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP, WPA-PSK, or WPA2-PSK.Usually, you should set up the strongest encryption that every device in the wireless network supports. For example, suppose you have a wireless network with the MAX-207HW2R and you do not have a RADIUS server. Therefore, there is no authentication. Suppose the wireless network has two devices. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.Note: It is recommended that wireless networks use WPA-PSK, WPA, or stronger encryption. The other types of encryption are better than none at all, but it is still possible for unauthorized wireless devices to figure out the original information pretty quickly.When you select WPA2 or WPA2-PSK in your MAX-207HW2R, you can also select an option (WPA compatible) to support WPA as well. In this case, if some of the devices 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 MAX-207HW2R.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every device in the wireless network must have the same key.6.5.3  WiFi Protected SetupYour MAX-207HW2R supports WiFi Protected Setup (WPS), which is an easy way to set up a secure wireless network. WPS is an industry standard specification, defined by the WiFi Alliance.WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Each WPS connection works Table 22   Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No SecurityWPAStatic WEPWPA-PSKStrongest WPA2-PSK WPA2
 Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide 69between two devices. Both devices must support WPS (check each device’s documentation to make sure). Depending on the devices you have, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (a unique Personal Identification Number that allows one device to authenticate the other) in each of the two devices. When WPS is activated on a device, it has two minutes to find another device that also has WPS activated. Then, the two devices connect and set up a secure network by themselves.6.5.3.1  Push Button ConfigurationWPS Push Button Configuration (PBC) is initiated by pressing a button on each WPS-enabled device, and allowing them to connect automatically. You do not need to enter any information. Not every WPS-enabled device has a physical WPS button. Some may have a WPS PBC button in their configuration utilities instead of or in addition to the physical button.Take the following steps to set up WPS using the button.1Ensure that the two devices you want to set up are within wireless range of one another. 2Look for a WPS button on each device. If the device does not have one, log into its configuration utility and locate the button (see the device’s User’s Guide for how to do this). The MAX-207HW2R’s WPS button is in the rear panel as shown next.Figure 24   The WPS Button on the MAX-207HW2R3Press the button on one of the devices (it doesn’t matter which). For the MAX-207HW2R you must press the WPS button for more than three seconds.4Within two minutes, press the button on the other device. The registrar sends the network name (SSID) and security key through an secure connection to the enrollee.
Chapter 6 The WIFI Configuration ScreenMAX-207HW2R User’s Guide70If you need to make sure that WPS worked, check the list of associated wireless clients in the AP’s configuration utility. If you see the wireless client in the list, WPS was successful.

A WAN configuration can include switched and permanent telephone circuits, terrestrial radio systems and satellite systems.7.1.1  What You Can Do in This Chapter•The Internet Connection screen (Section 7.2 on page 73) lets you set up your MAX-207HW2R’s Internet settings.•The WiMAX Configuration screen (Section 7.3 on page 75) lets set up the frequencies used by your MAX-207HW2R.•The WiMAX FC Table screen (Section 7.4 on page 80) lets you view BS information previously scanned by your MAX-207HW2R.7.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.WiMAX WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless networking standard, which provides high-bandwidth, wide-range wireless service across wireless Metropolitan Area Networks (MANs). ZyXEL is a member of the WiMAX Forum, the industry group dedicated to promoting and certifying interoperability of wireless broadband products.In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or a subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to maintain connectivity while switching their connection from one base station to another base station (handover) while subscriber stations use other standards that do not have this capability (IEEE 802.16-2004, for
Chapter 7 The WAN Configuration ScreensMAX-207HW2R User’s Guide72example). The following figure shows an MS-equipped notebook computer MS1 moving from base station BS1’s coverage area and connecting to BS2.Figure 25   WiMax: Mobile StationWiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations and mobile stations to local base stations. Numerous subscriber stations and mobile stations connect to the network through a single base station (BS), as in the following figure. Figure 26   WiMAX: Multiple Mobile StationsA 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 MAX-207HW2R and the base station are controlled by the base station. The MAX-207HW2R follows the base station’s configuration. AuthenticationWhen authenticating a user, the base station uses a third-party RADIUS or Diameter server known as an AAA (Authentication, Authorization and Accounting) server to authenticate the mobile or subscriber stations.
 Chapter 7 The WAN Configuration ScreensMAX-207HW2R User’s Guide 73The following figure shows a base station using an AAA server to authenticate mobile station MS, allowing it to access the Internet.Figure 27   Using an AAA ServerIn this figure, the dashed arrow shows the PKM (Privacy Key Management) secured connection between the mobile station and the base station, and the solid arrow shows the EAP secured connection between the mobile station, the base station and the AAA server.

Figure 30   Frequency RangesIn this figure, A is the WiMAX frequency range. “WiMAX frequency range” refers to the entire range of frequencies the MAX-207HW2R is capable of using to transmit and receive (see the Product Specifications appendix for details). In the figure, B shows the operator frequency range. This is the range of frequencies within the WiMAX frequency range supported by your operator (service provider).The operator range is subdivided into bandwidth steps. In the figure, each C is a bandwidth step.The arrow D shows the MAX-207HW2R searching for a connection.Have the MAX-207HW2R search only certain frequencies by configuring the downlink frequencies. Your operator can give you information on the supported frequencies. The downlink frequencies are points of the frequency range your MAX-207HW2R searches for an available connection. Use the Site Survey screen to set these bands. You can set the downlink frequencies anywhere within the WiMAX frequency range. In this example, the downlink frequencies have been set to search all of the operator range for a connection.7.3.2  Configuring Frequency SettingsYou need to set the MAX-207HW2R to scan one or more specific radio frequencies to find an available connection to a WiMAX base station. Use the WiMAX Configuration screen to define the radio frequencies to be searched for available wireless connections. Note: It may take several minutes for the MAX-207HW2R to find a connection.

MAX-207HW2R User’s Guide 83CHAPTER  8 The Port Configuration Screens8.1  OverviewUse these screens to enable NAT and configure port forwarding for the MAX-207HW2R.Network Address Translation (NAT) maps a host’s IP address within one network to a different IP address in another network. For example, you can use a NAT router to map one IP address from your ISP to multiple private IP addresses for the devices in your home network.8.1.1  What You Can Do in This Chapter•The General screen (Section 8.2 on page 84) lets you enable or disable NAT and to allocate memory for NAT and firewall rules.•The Port Forwarding screen (Section 8.3 on page 85) lets you look at the current port-forwarding rules in the MAX-207HW2R, and to enable, disable, activate, and deactivate each one.
Chapter 8 The Port Configuration ScreensMAX-207HW2R User’s Guide848.2  GeneralClick ADVANCED > NAT Configuration > General to enable or disable NAT and to allocate memory for NAT and firewall rules.Figure 32   ADVANCED > NAT Configuration > GeneralThe following table describes the labels in this screen.Table 28   ADVANCED > NAT Configuration > GeneralLABEL DESCRIPTIONEnable Network Address Translation Select this if you want to enable the Network Address Translation.Max NAT/Firewall Session Per User When computers use peer to peer applications, such as file sharing applications, they may use a large number of NAT sessions. If you do not limit the number of NAT sessions a single client can establish, this can result in all of the available NAT sessions being used. In this case, no additional NAT sessions can be established, and users may not be able to access the Internet. Each NAT session establishes a corresponding firewall session. Use this field to limit the number of NAT/firewall sessions each client computer can establish through the MAX-207HW2R. If your network has a small number of clients using peer to peer applications, you can raise this number to ensure that their performance is not degraded by the number of NAT sessions they can establish. If your network has a large number of users using peer to peer applications, you can lower this number to ensure no single client is using all of the available NAT sessions.

 Chapter 8 The Port Configuration ScreensMAX-207HW2R User’s Guide 858.3  Port Forwarding 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.Use the ADVANCED > NAT Configuration > Port Forwarding screen to forward incoming service requests to the server(s) on your local network. 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. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.For example, let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.Figure 33   Multiple Servers Behind NAT Example8.3.1  Port Forwarding OptionsClick ADVANCED > NAT Configuration > Port Forwarding to look at the current port-forwarding rules in the MAX-207HW2R, and to enable, disable,

Because some ISPs check this name you should enter your computer's  "Computer Name". • In Windows 2000: Click Start > Settings > Control Panel and then double-click the System icon. Select the Network Identification tab and then click the Properties button. Note the entry for the Computer Name field and enter it as the System Name.• In Windows XP: Click Start > My Computer > View system information and then click the Computer Name tab. Note the entry in the Full computer name field and enter it as the MAX-207HW2R System Name.
Chapter 9 The System Configuration ScreensMAX-207HW2R User’s Guide90Domain NameThe Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank, the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System Name) on each individual computer, the domain name can be assigned from the MAX-207HW2R via DHCP.DNS Server Address AssignmentUse DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The MAX-207HW2R can get the DNS server addresses in the following ways:1The 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 SYSTEM General screen.2If the ISP did not give you DNS server information, leave the DNS Server fields in the SYSTEM General screen set to 0.0.0.0 for the ISP to dynamically assign the DNS server IP addresses.9.2  Dynamic DNSDynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key.Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.
 Chapter 9 The System Configuration ScreensMAX-207HW2R User’s Guide 91Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.Click ADVANCED > System Configuration > Dynamic DNS to set up the MAX-207HW2R as a dynamic DNS client.Figure 36   ADVANCED > System Configuration > Dynamic DNSThe following table describes the labels in this screen.Table 32   ADVANCED > System Configuration > Dynamic DNSLABEL DESCRIPTIONDynamic DNS SetupEnable Dynamic DNS Select this to use dynamic DNS.Service Provider Select the name of your Dynamic DNS service provider.Dynamic DNS Type  Select the type of service that you are registered for from your Dynamic DNS service provider.Host Name  Enter the host name.

MAX-207HW2R User’s Guide 97CHAPTER  10 The Service ConfigurationScreens10.1  OverviewThe VOICE > Service Configuration screens allow you to set up your voice accounts and configure your QoS settings.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. Internet Telephony Service Provider (ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and provide it’s own VoIP service.Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to handle a telephone call. VoIP can use advanced voice coding techniques with compression to reduce the required bandwidth.10.1.1  What You Can Do in This Chapter•The SIP Setting screen (Section 10.2 on page 99) lets you setup and maintain your SIP account(s) in the MAX-207HW2R.•The Advanced SIP Settings screen (Section 10.2.1 on page 100) lets you set up and maintain advanced settings for each SIP account10.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.SIPThe Session Initiation Protocol (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 signaling is separate from the media for which it handles sessions. The media that is exchanged during the session can
Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide98use a different path from that of the signaling. SIP handles telephone calls and can interface with traditional circuit-switched telephone networks.SIP IdentitiesA SIP account uses an identity (sometimes referred to as a SIP address). A complete SIP identity is called a SIP URI (Uniform Resource Identifier). A SIP account's URI identifies the SIP account in a way similar to the way an e-mail address identifies an e-mail account. The format of a SIP identity is SIP-Number@SIP-Service-Domain.SIP NumberThe SIP number is the part of the SIP URI that comes before the “@” symbol. A SIP number can use letters like in an e-mail address (johndoe@your-ITSP.com for example) or numbers like a telephone number (1122334455@VoIP-provider.com for example).SIP Service DomainThe 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.SIP Register ServerA SIP register server maintains a database of SIP identity-to-IP address (or domain name) mapping. The register server checks your user name and password when you register. RTPWhen you make a VoIP call using SIP, the RTP (Real time Transport Protocol) is used to handle voice data transfer. See RFC 1889 for details on RTP.Use NATIf you know the NAT router’s public IP address and SIP port number, you can use the Use NAT feature to manually configure the MAX-207HW2R to use a them in the SIP messages. This eliminates the need for STUN or a SIP ALG. You must also configure the NAT router to forward traffic with this port number to the MAX-207HW2R.
 Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide 9910.1.3  Before you Begin• Ensure that you have all of your voice account information on hand.

 Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide 101•G.711 is a Pulse Code Modulation (PCM) waveform codec. PCM measures analog signal amplitudes at regular time intervals (sampling) and converts them into digital bits (quantization). Quantization “reads” the analog signal and then “writes” it to the nearest digital value. For this reason, a digital sample is usually slightly different from its analog original (this difference is known as “quantization noise”). G.711 provides excellent sound quality but requires 64kbps of bandwidth.•G.723 is an Adaptive Differential Pulse Code Modulation (ADPCM) waveform codec. Differential (or Delta) PCM is similar to PCM, but encodes the audio signal based on the difference between one sample and a prediction based on previous samples, rather than encoding the sample’s actual quantized value. Many thousands of samples are taken each second, and the differences between consecutive samples are usually quite small, so this saves space and reduces the bandwidth necessary. However, DPCM produces a high quality signal (high signal-to-noise ratio or SNR) for high difference signals (where the actual signal is very different from what was predicted) but a poor quality signal (low SNR) for low difference signals (where the actual signal is very similar to what was predicted). This is because the level of quantization noise is the same at all signal levels. Adaptive DPCM solves this problem by adapting the difference signal’s level of quantization according to the audio signal’s strength. A low difference signal is given a higher quantization level, increasing its signal-to-noise ratio. This provides a similar sound quality at all signal levels. G.723 provides high quality sound and requires 20 or 40 kbps.•G.729 is an Analysis-by-Synthesis (AbS) hybrid waveform codec. It uses a filter based on information about how the human vocal tract produces sounds. The codec analyzes the incoming voice signal and attempts to synthesize it using its list of voice elements. It tests the synthesized signal against the original and, if it is acceptable, transmits details of the voice elements it used to make the synthesis. Because the codec at the receiving end has the same list, it can exactly recreate the synthesized audio signal.G.729 provides good sound quality and reduces the required bandwidth to 8kbps.10.2.1.2  MWI (Message Waiting Indication)Enable Message Waiting Indication (MWI) enables your phone to give you a message–waiting (beeping) dial tone when you have one or more voice messages. Your VoIP service provider must have a messaging system that sends message-waiting-status SIP packets as defined in RFC 3842.

The MAX-207HW2R automatically tries to re-register your SIP account when one-half of this time has passed. (The SIP register server might have a different expiration.)Register Re-send Timer Enter the number of seconds the MAX-207HW2R waits before it tries again to register the SIP account, if the first try failed or if there is no response.Session Expires (SE) Enter the number of seconds the conversation can last before the call is automatically disconnected. Usually, when one-half of this time has passed, the MAX-207HW2R or the other party updates this timer to prevent this from happening.Min-SE Enter the minimum number of seconds the MAX-207HW2R accepts for a session expiration time when it receives a request to start a SIP session. If the request has a shorter time, the MAX-207HW2R rejects it.RTP Port RangeStart PortEnd PortEnter the listening port number(s) for RTP traffic, if your VoIP service provider gave you this information. Otherwise, keep the default values.To enter one port number, enter the port number in the Start Port and End Port fields.To enter a range of ports:• Type the port number at the beginning of the range in the Start Port field• Type the port number at the end of the range in the End Port field.Voice CompressionPrimary, Secondary, and Third CompressionSelect the type of voice coder/decoder (codec) that you want the MAX-207HW2R to use. G.711 provides high voice quality but requires more bandwidth (64 kbps).•G.729 requires only 8 kbps.•G.711A is typically used in Europe.•G.711u is typically used in North America and Japan.•G.723 provides good voice quality, and requires 20 or 40 kbps.The MAX-207HW2R must use the same codec as the peer. When two SIP devices start a SIP session, they must agree on a codec.For more on voice compression, see Voice Coding on page 100DTMF Mode controls how the MAX-207HW2R handles the tones that your telephone makes when you push its buttons. You should use the same mode your VoIP service provider uses.•RFC 2833 - send the DTMF tones in RTP packets.•PCM - send the DTMF tones in the voice data stream. This method works best when you are using a codec that does not use compression (like G.711). Codecs that use compression (like G.729) can distort the tones.•SIP INFO - send the DTMF tones in SIP messages.Table 37   VOICE > Service Configuration > SIP Settings > Show Advanced Setup LABEL DESCRIPTION

A calls B. 1A sends a SIP INVITE request to B. This message is an invitation for B to participate in a SIP telephone call. 2B sends a response indicating that the telephone is ringing.3B sends an OK response after the call is answered. 4A then sends an ACK message to acknowledge that B has answered the call. 5Now A and B exchange voice media (talk). 6After talking, A hangs up and sends a BYE request. 7B replies with an OK response confirming receipt of the BYE request and the call is terminated.Table 39   SIP Call ProgressionA B1.

 Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide 10710.3.2  SIP Client ServerSIP is a client-server protocol. A SIP client is an application program or device that sends SIP requests. A SIP server responds to the SIP requests. When you use SIP to make a VoIP call, it originates at a client and terminates at a server. A SIP client could be a computer or a SIP phone. One device can act as both a SIP client and a SIP server. 10.3.3  SIP User Agent A SIP user agent can make and receive VoIP telephone calls. This means that SIP can be used for peer-to-peer communications even though it is a client-server protocol. In the following figure, either A or B can act as a SIP user agent client to initiate a call. A and B can also both act as a SIP user agent to receive the call.Figure 42   SIP User Agent10.3.4  SIP Proxy ServerA SIP proxy server receives requests from clients and forwards them to another server.In the following example, you want to use client device A to call someone who is using client device C. 1The client device (A in the figure) sends a call invitation to the SIP proxy server (B).AB
Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide1082The SIP proxy server forwards the call invitation to C.Figure 43   SIP Proxy Server10.3.5  SIP Redirect ServerA SIP redirect server accepts SIP requests, translates the destination address to an IP address and sends the translated IP address back to the device that sent the request. Then the client device that originally sent the request can send requests to the IP address that it received back from the redirect server. Redirect servers do not initiate SIP requests. In the following example, you want to use client device A to call someone who is using client device C. 1Client device A sends a call invitation for C to the SIP redirect server (B).2The SIP redirect server sends the invitation back to A with C’s IP address (or domain name).ACB12
 Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide 1093Client device A then sends the call invitation to client device C.Figure 44   SIP Redirect Server10.3.6  NAT and SIPThe MAX-207HW2R must register its public IP address with a SIP register server. If there is a NAT router between the MAX-207HW2R and the SIP register server, the MAX-207HW2R probably has a private IP address. The MAX-207HW2R lists its IP address in the SIP message that it sends to the SIP register server. NAT does not translate this IP address in the SIP message. The SIP register server gets the MAX-207HW2R’s IP address from inside the SIP message and maps it to your SIP identity. If the MAX-207HW2R has a private IP address listed in the SIP message, the SIP server cannot map it to your SIP identity. See Chapter 8 The Port Configuration Screens for more information.Use a SIP ALG (Application Layer Gateway), Use NAT, STUN, or outbound proxy to allow the MAX-207HW2R to list its public IP address in the SIP messages.10.3.7  DiffServDiffServ is a class of service (CoS) model that marks packets so that they receive specific per-hop treatment at DiffServ-compliant network devices along the route based on the application types and traffic flow. Packets are marked with DiffServ Code Points (DSCPs) indicating the level of service desired. This allows the intermediary DiffServ-compliant network devices to handle the packets differently depending on the code points without the need to negotiate paths or remember state information for every flow. In addition, applications do not have to request a particular service or give advanced notice of where the traffic is going.ACB132
Chapter 10 The Service Configuration ScreensMAX-207HW2R User’s Guide11010.3.8  DSCP and Per-Hop Behavior DiffServ defines a new DS (Differentiated Services) field to replace the Type of Service (TOS) field in the IP header. The DS field contains a 2-bit unused field and a 6-bit DSCP field which can define up to 64 service levels. The following figure illustrates the DS field. Figure 45   DiffServ: Differentiated Service FieldDSCP is backward compatible with the three precedence bits in the ToS octet so that non-DiffServ compliant, ToS-enabled network device will not conflict with the DSCP mapping. The DSCP value determines the forwarding behavior, the PHB (Per-Hop Behavior), that each packet gets across the DiffServ network. Based on the marking rule, different kinds of traffic can be marked for different priorities of forwarding. Resources can then be allocated according to the DSCP values and the configured policies.DSCP(6-bit)Unused(2-bit)

This lets the MAX-207HW2R reduce the bandwidth that a call uses by not transmitting “silent packets” when you are not speaking.When using VAD, the MAX-207HW2R generates comfort noise when the other party is not speaking. The comfort noise lets you know that the line is still connected as total silence could easily be mistaken for a lost connection.Echo Cancellation G.168 is an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.

MAX-207HW2R User’s Guide 127CHAPTER  13 The Certificates Screens13.1  OverviewUse the TOOLS > Certificates screens to importmanage public key certificates on the MAX-207HW2R.The MAX-207HW2R can use public key certificates (also sometimes called “digital IDs”) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owner’s identity and public key. Certificates provide a way to exchange public keys for use in authentication.Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions (to name a few) receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on his site to be issued to all visiting web browsers to let them know that the site is legitimate.13.1.1  What You Can Do in This Chapter•The My Certificates screen (Section 13.2 on page 128) lets you import the MAX-207HW2R’s CA-signed certificates.•The Trusted CAs screen (Section 13.3 on page 129) lets you import trusted CA-signed certificates.13.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.Certificate AuthoritiesA Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the MAX-207HW2R to generate certification requests that contain identifying

Chapter 13 The Certificates ScreensMAX-207HW2R User’s Guide13013.4.1  Certificate AuthoritiesWhen using public-key cryptology for authentication, each host has two keys. One key is public and can be made openly available. The other key is private and must be kept secure. These keys work like a handwritten signature (in fact, certificates are often referred to as “digital signatures”). Only you can write your signature exactly as it ought to look. When people know what your signature ought to look like, they can verify whether something was signed by you, or by someone else. In the same way, your private key “writes” your digital signature and your public key allows people to verify whether data was signed by you, or by someone else. This process works as follows.1Tim wants to send a message to Jenny. He needs her to be sure that it comes from him, and that the message content has not been altered by anyone else along the way. Tim generates a public key pair (one public key and one private key). 2Tim keeps the private key and makes the public key openly available. This means that anyone who receives a message seeming to come from Tim can read it and verify whether it is really from him or not. 3Tim uses his private key to sign the message and sends it to Jenny.4Jenny receives the message and uses Tim’s public key to verify it. Jenny knows that the message is from Tim, and she knows that although other people may have been able to read the message, no-one can have altered it (because they cannot re-sign the message with Tim’s private key).5Additionally, Jenny uses her own private key to sign a message and Tim uses Jenny’s public key to verify the message.The MAX-207HW2R uses certificates based on public-key cryptology to authenticate users attempting to establish a connection, not to encrypt the data that you send after establishing a connection. The method used to secure the data that you send through an established connection depends on the type of connection. For example, a VPN tunnel might use the triple DES encryption algorithm.The certification authority uses its private key to sign certificates. Anyone can then use the certification authority’s public key to verify the certificates.A certification path is the hierarchy of certification authority certificates that validate a certificate. The MAX-207HW2R does not trust a certificate if any certificate on its path has expired or been revoked.
 Chapter 13 The Certificates ScreensMAX-207HW2R User’s Guide 131Certification authorities maintain directory servers with databases of valid and revoked certificates. A directory of certificates that have been revoked before the scheduled expiration is called a CRL (Certificate Revocation List). The MAX-207HW2R can check a peer’s certificate against a directory server’s list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure).13.4.1.1  Advantages of CertificatesCertificates offer the following benefits.• The MAX-207HW2R only has to store the certificates of the certification authorities that you decide to trust, no matter how many devices you need to authenticate. • Key distribution is simple and very secure since you can freely distribute public keys and you never need to transmit private keys.13.4.1.2  Self-signed CertificatesYou can have the MAX-207HW2R act as a certification authority and sign its own certificates.13.4.1.3  Factory Default CertificateThe MAX-207HW2R generates its own unique self-signed certificate when you first turn it on. This certificate is referred to in the GUI as the factory default certificate. 13.4.1.4  Certificate File FormatsAny certificate that you want to import has to be in one of these file formats:• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable form.• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital signatures) that may be encrypted. A PKCS #7 file is used to transfer a public key certificate. The private key is not included. The MAX-207HW2R currently allows the importation of a PKS#7 file that contains a single certificate. • PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses lowercase letters, uppercase letters and numerals to convert a binary PKCS#7 certificate into a printable form.Note: Be careful to not convert a binary file to text during the transfer process. It is easy for this to occur since many programs use text files by default.
Chapter 13 The Certificates ScreensMAX-207HW2R User’s Guide13213.4.2  Verifying a CertificateBefore you import a certificate into the MAX-207HW2R, you should verify that you have the correct certificate. This is especially true of trusted certificates since the MAX-207HW2R also trusts any valid certificate signed by any of the imported trusted certificates.13.4.2.1  Checking the Fingerprint of a Certificate on Your ComputerA certificate’s fingerprints are message digests calculated using the MD5 or SHA1 algorithms. The following procedure describes how to check a certificate’s fingerprint to verify that you have the actual certificate. 1Browse to where you have the certificate saved on your computer. 2Make sure that the certificate has a “.cer” or “.crt” file name extension. (On some Linux distributions, the file extension may be “.der”.)Figure 55   Remote Host Certificates

If it does not match, the MAX-207HW2R will disconnect the session immediately.4There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time.Remote Management and NATWhen NAT is enabled:• Use the MAX-207HW2R’s WAN IP address when configuring from the WAN. • Use the MAX-207HW2R’s LAN IP address when configuring from the LAN.System TimeoutThere is a default system management idle timeout of five minutes (three hundred seconds). The MAX-207HW2R automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when a statistics screen is polling.SNMPSimple Network Management Protocol (SNMP) is a protocol used for exchanging management information between network devices. SNMP is a member of the
 Chapter 14 The Remote Management ScreensMAX-207HW2R User’s Guide 137TCP/IP protocol suite.

Chapter 14 The Remote Management ScreensMAX-207HW2R User’s Guide14014.5  SNMPAn SNMP managed network consists of two main types of component: agents and a manager.Figure 60   SNMP Management ModelAn agent is a management software module that resides in a managed device (the MAX-207HW2R). An agent translates the local management information from the managed device into a form compatible with SNMP. The manager is the console through which network administrators perform network management functions. It executes applications that control and monitor managed devices. The managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include such as number of packets received, node port status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a manager and agents to communicate for the purpose of accessing these objects. The MAX-207HW2R supports MIB II that is defined in RFC-1213 and RFC-1215. The focus of the MIBs is to let administrators collect statistical data and monitor status and performance.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations: • Get - Allows the manager to retrieve an object variable from the agent.
 Chapter 14 The Remote Management ScreensMAX-207HW2R User’s Guide 141• GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. • Set - Allows the manager to set values for object variables within an agent. • Trap - Used by the agent to inform the manager of some events.14.5.1  SNMP TrapsThe MAX-207HW2R sends traps to the SNMP manager when any of the following events occurs:          Table 56   SNMP TrapsTRAP # TRAP NAME DESCRIPTION0coldStart (defined in RFC-1215)A trap is sent after booting (power on).1warmStart (defined in RFC-1215)A trap is sent after booting (software reboot).4authenticationFailure (defined in RFC-1215)A trap is sent to the manager when receiving any SNMP get or set requirements with the wrong community (password).6whyReboot (defined in ZYXEL-MIB) A trap is sent with the reason of restart before rebooting when the system is going to restart (warm start).6a For intentional reboot: A trap is sent with the message "System reboot by user!" if reboot is done intentionally, (for example, download new files, CI command "sys reboot", etc.).6b For fatal error:  A trap is sent with the message of the fatal code if the system reboots because of fatal errors.

MAX-207HW2R User’s Guide 145CHAPTER  15 The Firewall Screens15.1  OverviewUse the TOOLS > Firewall screens to manage MAX-207HW2R’s firewall security measures.Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network. Of course, firewalls cannot solve every security problem.A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself.15.1.1  What You Can Do in This Chapter•The General screen (Section 15.2 on page 146) lets you configure the basic settings for your firewall.•The Services screen (Section 15.3 on page 149) lets you enable service blocking, set up the date and time service blocking is effective, and to maintain the list of services you want to block.15.1.2  What You Need to KnowThe following terms and concepts may help as you read through this chapter.About the MAX-207HW2R FirewallThe MAX-207HW2R firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated. The MAX-207HW2R's purpose is to allow a private Local Area Network (LAN) to be securely connected to
Chapter 15 The Firewall ScreensMAX-207HW2R User’s Guide146the Internet. The MAX-207HW2R can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The MAX-207HW2R is installed between the LAN and a WiMAX base station connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The MAX-207HW2R has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, “inbound access” is not allowed (by default) unless the remote host is authorized to use a specific service.15.2  Firewall SettingThis section describes firewalls and the built-in MAX-207HW2R’s firewall features.15.2.1  Firewall Rule DirectionsFigure 64   Firewall Rule DirectionsLAN-to-WAN rules are local network to Internet firewall rules. The default is to forward all traffic from your local network to the Internet. You can block certain LAN-to-WAN traffic in the Services screen (click the Services tab). All services displayed in the Blocked Services list box are LAN-to-WAN firewall rules that block those services originating from the LAN. Blocked LAN-to-WAN packets are considered alerts. Alerts are “higher priority logs” that include system errors, attacks and attempted access to blocked web sites. Alerts appear in red in the View Log screen. You may choose to have alerts e-mailed immediately in the Log Settings screen.
 Chapter 15 The Firewall ScreensMAX-207HW2R User’s Guide 147LAN-to-LAN/MAX-207HW2R means the LAN to the MAX-207HW2R LAN interface. This is always allowed, as this is how you manage the MAX-207HW2R from your local computer.WAN-to-LAN rules are Internet to your local network firewall rules. The default is to block all traffic from the Internet to your local network. How can you forward certain WAN to LAN traffic? You may allow traffic originating from the WAN to be forwarded to the LAN by:• Configuring NAT port forwarding rules.•Configuring WAN or LAN & WAN access for services in the Remote MGMT screens or SMT menus. When you allow remote management from the WAN, you are actually configuring WAN-to-WAN/MAX-207HW2R firewall rules. WAN-to-WAN/MAX-207HW2R firewall rules are Internet to the MAX-207HW2R WAN interface firewall rules. The default is to block all such traffic. When you decide what WAN-to-LAN packets to log, you are in fact deciding what WAN-to-LAN and WAN-to-WAN/MAX-207HW2R packets to log. Forwarded WAN-to-LAN packets are not considered alerts.15.2.2  Triangle RouteWhen the firewall is on, your MAX-207HW2R acts as a secure gateway between your LAN and the Internet. In an ideal network topology, all incoming and outgoing network traffic passes through the MAX-207HW2R to protect your LAN against attacks.Figure 65   Ideal Firewall Setup
