User’s Guide 25CHAPTER 2 The WPS Button2.1 OverviewYour NBG4115 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 between 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.For more information on using WPS, see Section 6.4 on page 68.Company Confidential

Chapter 4Connection WizardUser’s Guide 454.5.2 PPPoE ConnectionPoint-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF (Internet Engineering Task Force) standard specifying how a host personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). One of the benefits of PPPoE is the ability to let end users 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 specific users.Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber’s site.By implementing PPPoE directly on the NBG4115 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG4115 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.Figure 17 Wizard Step 3: PPPoE ConnectionThe following table describes the labels in this screen.Table 12 Wizard Step 3: PPPoE ConnectionLABEL DESCRIPTIONISP Parameter for Internet AccessConnection Type Select the PPP over Ethernet option for a dial-up connection.Service Name Type the name of your service provider.User Name Type the user name given to you by your ISP.

If your networks are isolated from the Internet, for instance, 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.You can obtain your IP address from the IANA, from an ISP or have it assigned by 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 Table 15 Wizard Step 3: Your IP AddressLABEL DESCRIPTIONGet automatically from your ISP Select this option If your ISP did not assign you a fixed IP address. This is the default selection. If you choose this option, skip directly to Section 4.5.10 on page 52.Use fixed IP address provided by your ISP Select this option if you were given IP address and/or DNS server settings by the ISP.

Chapter 4Connection WizardUser’s Guide50local 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.Note: 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.4.5.7 IP Address and Subnet MaskSimilar 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. 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 NBG4115, 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 NBG4115 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 NBG4115 unless you are instructed to do otherwise.4.5.8 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 NBG4115 can get the DNS server addresses in the following ways.Company Confidential
Chapter 4Connection WizardUser’s Guide 511The 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 Wizard and/or WAN> Internet Connectionscreen.2If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN>Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses.4.5.9 WAN IP and DNS Server Address AssignmentThe following wizard screen allows you to assign a fixed WAN IP address and DNS server addresses.

System DNS Server Address Assignment (if applicable)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 computer before you can access it. The NBG4115 uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server.Company Confidential

There are two ways to set up your 3G options.1Use the Wizard, which was introduced in the Quick Start Guide. The wizard is good for getting up and running in as little time as possible. It allows you to configure the minimum number of options required to get connected.2Use the Web Configurator’s Network options. This is handy because it gives you access to other options not available in the Wizard, allowing you to have more control over your device.This tutorial shows you how to do the second one.

Some video games may have higher performance expectations than other types of software. As such, they tend to require more finely tuned Quality of Service (QoS) prioritization. If the data packets from a game are assigned a lower priority by the NBG4115, then they may take longer to reach their destination; but if they are given a higher priority, then they should arrive at their destination marginally faster. This is because Internet servers that rely on QoS to sort packets that are in transit generally pass higher priority packets on first, while lower priority packets are held back slightly longer.When this happens on a single server with a single data packet, your gameplay is not affected. When it happens over 15 servers from beginning to end with thousands of bytes of data, then the build up of low-priority latency can become significant. For Massively Multiplayer Online (MMOs) and First Person Shooters (FPS) (which account for 3-4% of all Internet-related traffic) a latency difference of even 200 milliseconds is enough to ruin the gaming experience.Company Confidential
Chapter 6TutorialsUser’s Guide66Bandwidth management allows you to set up custom parameters on the NBG4115 so that whenever you play a game, the QoS is automatically upgraded to the highest priority in order to ensure your game data packets are plucked first from the pool of incoming information and sent on ahead of lower priority packets.This tutorial shows you how to set up your NBG4115 for gaming.1In the Web Configurator, expand the navigation pane’s Management category and then select BandwidthMGMT2Select the Advanced tab.Company Confidential

This example uses the NBG4115 as the AP and NWD210N as the wireless client which connects to a notebook. Note: The wireless client must be a WPS-aware device (for example, a WPS USB adapter or PCI card).There are two WPS methods for creating a secure connection. This tutorial shows you how to do both.•Push Button Configuration (PBC) - create a secure wireless network simply by pressing a button. See Section 6.4.1 on page 68.This is the easier method.•PIN Configuration - create a secure wireless network simply by entering a wireless client's PIN (Personal Identification Number) in the NBG4115’s interface. See Section 6.4.2 on page 70. This is the more secure method, since one device can authenticate the other.6.4.1 Push Button Configuration (PBC)1Make sure that your NBG4115 is turned on and that it is within range of your computer. 2Make sure that you have installed the wireless client (this example uses the NWD210N) driver and utility in your notebook.Company Confidential
Chapter 6TutorialsUser’s Guide 693In the wireless client utility, find the WPS settings. Enable WPS and press the WPS button (Start or WPS button)4Log into NBG4115’s Web Configurator and press the Push Button button in the Network > Wireless Client >WPS Station screen. Note: Your NBG4115 has a WPS button located on its panel, as well as a WPS button in its configuration utility. Both buttons have exactly the same function; you can use one or the other.Note: It doesn’t matter which button is pressed first. You must press the second button within two minutes of pressing the first one. The NBG4115 sends the proper configuration settings to the wireless client. This may take up to two minutes. Then the wireless client is able to communicate with the NBG4115 securely. The following figure shows you an example to set up wireless network and security by pressing a button on both NBG4115 and wireless client (the NWD210N in this example).Figure 29 Example WPS Process: PBC MethodWireless Client ZyXEL DeviceSECURITY INFOCOMMUNICATIONWITHIN 2 MINUTESCompany Confidential

ZyXEL's bandwidth management feature allows you to specify bandwidth management rules based on an application or subnet. Use the Management > Bandwidth MGMT > Advanced screen to configure bandwidth management for your network.6.6.1 Bandwidth Management by ApplicationFor this example, your company’s customer support department wants to prioritize VoIP, e-mail and MSN Messenger services. In the Priority Queue table, VoIP and e-mail services are already pre-defined. However, you still need to add MSN Messenger in the list (refer to Section 6.6.2 on page 75).Company Confidential

Do the same for E-mail. For the rest of the applications, click Enable if you need these services and set the priority to Low.Note: You can also leave the Enable field blank for the rest of the applications. In doing so, the NBG4115 does not apply bandwidth management to these services.6.6.2 Custom Bandwidth ManagementAside from the VOIP and e-mail services, you need to set the priority for MSN Messenger. To do this, add the service in the Priority Queue table of the Management > Bandwidth MGMT > Advanced screen.Figure 38 Tutorial: Adding TFTP to Priority QueueTo add the MSN Messenger service in the Priority Queue:Company Confidential

You want to use the multimedia room’s Internet connection to upload some videos to the website. You also use this room for video conferences, radio broadcasts, live video streaming, and so on throughout the day. While these media-heavy activities are going on, you still want to keep uploading the videos in the background. As such, you want to dedicate the minimum amount of bandwidth for this traffic.You know the following:•Multimedia room’s LAN IP range: 192.168.1.1 to 192.168.1.34•IP Address of the computer uploading through FTP: 192.168.1.34•Services you want to configure:Click the Edit icon in Management > Bandwidth MGMT > Advanced to open the following screen.

See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 41 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your NBG4115 is the AP.APCompany Confidential
Chapter 7Wireless LANUser’s Guide827.1.1 What You Can Do in this Chapter•Use the General screen (Section 7.2 on page 85) to enable the Wireless LAN, enter the SSID and select the wireless security mode.•Use the MAC Filter screen (Section 7.3 on page 90) to allow or deny wireless stations based on their MAC addresses from connecting to the NBG4115.•Use the Advanced screen (Section 7.4 on page 92) to allow intra-BSS networking and set the RTS/CTS Threshold.•Use the QoS screen (Section 7.5 on page 94) to ensure Quality of Service (QoS) in your wireless network.•Use the WPS screen (Section 7.6 on page 97) to quickly set up a wireless network with strong security, without having to configure security settings manually.•Use the WPS Station screen (Section 7.7 on page 98) to add a wireless station using WPS. •Use the Scheduling screen (Section 7.8 on page 99) to set the times your wireless LAN is turned on and off.7.1.2 What You Should KnowEvery wireless network must follow these basic guidelines.•Every wireless client in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.•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.•Every wireless client in the same wireless network must use security compatible with the AP.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.Wireless Security OverviewThe following sections introduce different types of wireless security you can set up in the wireless network.SSIDNormally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.Company Confidential
Chapter 7Wireless LANUser’s Guide 83This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.MAC Address FilterEvery wireless client 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 wireless client, see the appropriate User’s Guide or other documentation.You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.User AuthenticationYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.For wireless networks, there are two typical places to store the user names and passwords for each user.•In the AP: this feature is called a local user database or a local database.•In a RADIUS server: this is a server used in businesses more than in homes.If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users.Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.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.Company Confidential
Chapter 7Wireless LANUser’s Guide84Local user databases also have an additional limitation that is explained in the next section.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.The types of encryption you can choose depend on the type of user authentication. (See Section on page 83 for information about this.)For example, if the wireless network has a RADIUS server, you can choose WPAor 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 wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. 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. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly.Note: It is not possible to use WPA-PSK,WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database.When you select WPA2 or WPA2-PSK in your NBG4115, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPACompatible option in the NBG4115.Table 25 Types of Encryption for Each Type of AuthenticationNO AUTHENTICATION RADIUS SERVERWeakest No SecurityWPAStatic WEPWPA-PSKStrongestWPA2-PSKWPA2Company Confidential
Chapter 7Wireless LANUser’s Guide 85Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key.WPSWiFi Protected Setup (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. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 6.4 on page 68.7.2 General Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode.Note: If you are configuring the NBG4115 from a computer connected to the wireless LAN and you change the NBG4115’s SSID, channel or security settings, you will lose your wireless connection when you press Apply to confirm. You must then change the wireless settings of your computer to match the NBG4115’s new settings.Click Network > Wireless LAN to open the General screen.Figure 42 Network > Wireless LAN > General Company Confidential

User’s Guide 101CHAPTER 8 WAN8.1 OverviewThis chapter discusses the NBG4115’s WAN screens. Use these screens to configure your NBG4115 for Internet access.A WAN (Wide Area Network) connection is an outside connection to another network or the Internet. It connects your private networks (such as a LAN (Local Area Network) and other networks, so that a computer in one location can communicate with computers in other locations.Figure 53 LAN and WANSee the chapter about the connection wizard for more information on the fields in the WAN screens.8.2 What You Can Do in this Chapter•Use the Internet Connection (Section 8.3 on page 105) screen to enter your ISP information and set how the computer acquires its IP, DNS and WAN MAC addresses.•Use the Advanced (Section 8.4 on page 113) screen to enable multicasting, configure Windows networking and bridge.WANLANCompany Confidential
Chapter 8WANUser’s Guide1028.2.1 What You Need To KnowThe following terms and concepts may help as you read through this chapter.Encapsulation MethodEncapsulation is used to include data from an upper layer protocol into a lower layer protocol. To set up a WAN connection to the Internet, you need to use the same encapsulation method used by your ISP (Internet Service Provider). If your ISP offers a dial-up Internet connection using PPPoE (PPP over Ethernet) or PPTP (Point-to-Point Tunneling Protocol), they should also provide a username and password (and service name) for user authentication.WAN IP AddressThe WAN IP address is an IP address for the NBG4115, which makes it accessible from an outside network. It is used by the NBG4115 to communicate with other devices in other networks. It can be static (fixed) or dynamically assigned by the ISP each time the NBG4115 tries to access the Internet.If your ISP assigns you a static WAN IP address, they should also assign you the subnet mask and DNS server IP address(es) (and a gateway IP address if you use the Ethernet or ENET ENCAP encapsulation method).DNS Server Address AssignmentUse Domain Name System (DNS) 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 NBG4115 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, manually enter them in the DNS server fields.2If your ISP dynamically assigns the DNS server IP addresses (along with the NBG4115’s WAN IP address), set the DNS server fields to get the DNS server address from the ISP. Company Confidential
Chapter 8WANUser’s Guide 103WAN MAC AddressThe MAC address screen allows users to configure the WAN port's MAC address by either using the factory default or cloning the MAC address from a computer on your LAN. Choose Factory Default to select the factory assigned default MAC Address.Otherwise,click Clone the computer's MAC address - IP Address and enter the IP address of the computer on the LAN whose MAC you are cloning. Once it is successfully configured, the address will be copied to configuration file. It is recommended that you clone the MAC address prior to hooking up the WAN Port.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. Figure 54 Multicast ExampleIn the multicast example above, systems A and B comprise one multicast group. In multicasting, the server only needs to send one data stream and this is delivered to systems A and B. 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. The NBG4115 supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the NBG4115 queries all directly connected networks to gather group membership. After that, the NBG4115 periodically updates this information. IP multicasting can be enabled/disabled on the NBG4115 LAN and/or WAN interfaces in the Web Configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.NetBIOS over TCP/IP NetBIOS (Network Basic Input/Output System) are TCP or UDP broadcast packets that enable a computer to connect to and communicate with a LAN. For some dial-ServerABCompany Confidential
Chapter 8WANUser’s Guide104up 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.Auto-BridgeIn the rear panel of your NBG4115, you can see four LAN ports (1 to 2) and one WAN port. The WAN port is for your Internet access connection, and the LAN ports are for your network devices. The WAN port has a different IP address from the LAN ports. When you enable auto-bridging in your NBG4115, all three ports (2 LAN ports and the WAN port) share the same IP address. This might happen if you put the NBG4115 behind a NAT router that assigns it this IP address. When the NBG4115 is in auto-bridge mode, the NBG4115 acts as an AP and all the interfaces (LAN, WAN and WLAN) are bridged. In this mode, your NAT, DHCP server and firewall on the NBG4115 are not available. You do not have to reconfigure them if you return to router mode.Auto-bridging only works under the following conditions:•The WAN IP must be 192.168.x.y (where x and y must be from zero to nine). If the LAN IP address and the WAN IP address are in the same subnet but x or y is greater than nine, the device operates in router mode (with firewall available).•The device must be in Router Mode (see Chapter 22 on page 195 for more information) for auto-bridging to become active.Company Confidential

Chapter 8WANUser’s Guide 107One 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 NBG4115 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the NBG4115 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.This screen displays when you select the PPPoE connection type.Figure 56 Network > WAN > Internet Connection: PPPoEThe following table describes the labels in this screen.Table 37 Network > WAN > Internet Connection: PPPoELABEL DESCRIPTIONISP Parameters for Internet AccessConnection Type Select PPP over Ethernet if you connect to your Internet via dial-up.Service Name Type the PPPoE service name provided to you.

User’s Guide 125CHAPTER 11 NAT11.1 Overview 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 is changed to a different IP address known within another network.The figure below is a simple illustration of a NAT network. 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 to the devices (A to D) connected to your NBG4115. The ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet. All traffic coming from A to D going out to the Internet use the IP address of the NBG4115, which is 192.168.1.1.Figure 65 NAT ExampleThis chapter discusses how to configure NAT on the NBG4115.Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the NBG4115.A: 192.168.1.33B: 192.168.1.34C: 192.168.1.35IP address 192.168.1.1WANLANassigned by ISPFTP, Telnet, SNMPPort 80Ports 21 to 25Company Confidential

Global/LocalThis denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note: Inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. An inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information.Note: NAT never changes the IP address (either local or global) of an outside host.Table 45 NAT DefinitionsITEM DESCRIPTIONInside This refers to the host on the LAN.Outside This refers to the host on the WAN.Local This refers to the packet address (source or destination) as the packet travels on the LAN.Global This refers to the packet address (source or destination) as the packet travels on the WAN.Company Confidential
Chapter 11NATUser’s Guide 127What NAT DoesIn the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed.The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world. If you do not define any servers , NAT offers the additional benefit of firewall protection. With no servers defined, your NBG4115 filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631,The IP Network Address Translator (NAT).How NAT WorksEach packet has two addresses – a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address in each packet and then forwards it to the Internet. The NBG4115 keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.Figure 66 How NAT WorksCompany Confidential

Chapter 11NATUser’s Guide13211.5 Technical ReferenceThe following section contains additional technical information about the NBG4115 features described in this chapter.11.5.1 NATPort Forwarding: Services and Port NumbersA port forwarding 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 Application 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.Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP.11.5.2 NAT Port Forwarding ExampleLet'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).

Chapter 11NATUser’s Guide 133addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.Figure 70 Multiple Servers Behind NAT Example11.5.3 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The NBG4115 records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the NBG4115's WAN port receives a response with a specific port number and protocol ("incoming" port), the NBG4115 forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.Company Confidential
Chapter 11NATUser’s Guide13411.5.4 Trigger Port Forwarding Example The following is an example of trigger port forwarding.Figure 71 Trigger Port Forwarding Process: Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the NBG4115 to record Jane’s computer IP address. The NBG4115 associates Jane's computer IP address with the "incoming" port range of 6970-7170.3The Real Audio server responds using a port number ranging between 6970-7170.4The NBG4115 forwards the traffic to Jane’s computer IP address. 5Only Jane can connect to the Real Audio server until the connection is closed or times out. The NBG4115 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). 11.5.5 Two Points To Remember About Trigger Ports1Trigger events only happen on data that is going coming from inside the NBG4115 and going to the outside.2If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it.Company Confidential

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.DynDNS Wildcard 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.Note: If you have a private WAN IP address, then you cannot use Dynamic DNS.

User’s Guide 141CHAPTER 13Firewall13.1 OverviewUse these screens to enable and configure the firewall that protects your NBG4115 and your LAN from unwanted or malicious traffic.Enable the firewall to protect your LAN computers from attacks by hackers on the Internet and control access between the LAN and WAN. By default the firewall:•allows traffic that originates from your LAN computers to go to all of the networks. •blocks traffic that originates on the other networks from going to the LAN. The following figure illustrates the default firewall action. User A can initiate an IM (Instant Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2). However other traffic initiated from the WAN is blocked (3 and 4).Figure 73 Default Firewall Action13.1.1 What You Can Do in this Chapter•Use the General screen(Section 13.2 on page 144) to enable or disable the NBG4115’s firewall.•Use the Services screen (Section 13.3 on page 144) screen enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them.

Chapter 13FirewallUser’s Guide14213.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.What is a Firewall?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 a network that is not trusted. 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. Stateful Inspection Firewall Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises.About the NBG4115 FirewallThe NBG4115’s firewall feature physically separates the LAN and the WAN and acts as a secure gateway for all data passing between the networks.It is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (clickthe General tab under Firewall and then click the EnableFirewall check box). The NBG4115's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The NBG4115 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 NBG4115 is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.Company Confidential
Chapter 13FirewallUser’s Guide 143The NBG4115 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.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.Guidelines For Enhancing Security With Your Firewall1Change the default password via Web Configurator. 2Think about access control before you connect to the network in any way, including attaching a modem to the port. 3Limit who can access your router. 4Don't enable any local service (such as NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. 6Protect against IP spoofing by making sure the firewall is active. 7Keep the firewall in a secured (locked) room.

Select LAN to reply to incoming LAN Ping requests.Select WAN to reply to incoming WAN Ping requests. Otherwise select LAN & WAN to reply to all incoming LAN and WAN Ping requests. Do not respond to requests for unauthorized servicesSelect this option to prevent hackers from finding the NBG4115 by probing for unused ports. If you select this option, the NBG4115 will not respond to port request(s) for unused ports, thus leaving the unused ports and the NBG4115 unseen. By default this option is not selected and the NBG4115 will reply with an ICMP Port Unreachable packet for a port probe on its unused UDP ports, and a TCP Reset packet for a port probe on its unused TCP ports. Note that the probing packets must first traverse the NBG4115's firewall mechanism before reaching this anti-probing mechanism. Therefore if the firewall mechanism blocks a probing packet, the NBG4115 reacts based on the firewall policy, which by default, is to send a TCP reset packet for a blocked TCP packet. You can use the command "sys firewall tcprst rst [on|off]" to change this policy. When the firewall mechanism blocks a UDP packet, it drops the packet without sending a response packet.Apply Click Apply to save the settings.

User’s Guide 147CHAPTER 14Content Filtering14.1 OverviewThis chapter provides a brief overview of content filtering using the embedded web GUI.Internet content filtering allows you to create and enforce Internet access policies tailored to your needs. Content filtering is the ability to block certain web features or specific URL keywords.14.1.1 What You Can Do in this ChapterUse the Filter (Section 14.2 on page 148) screen to restrict web features, add keywords for blocking and designate a trusted computer.14.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.Content Filtering ProfilesContent filtering allows you to block certain web features, such as cookies, and/or block access to specific web sites. For example, you can configure one policy that blocks John Doe’s access to arts and entertainment web pages.A content filtering profile conveniently stores your custom settings for the following features.Keyword Blocking URL CheckingThe NBG4115 checks the URL’s domain name (or IP address) and file path separately when performing keyword blocking. The URL’s domain name or IP address is the characters that come before the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the domain name is www.zyxel.com.tw.Company Confidential
Chapter 14Content FilteringUser’s Guide148The file path is the characters that come after the first slash in the URL. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the file path is news/pressroom.php.Since the NBG4115 checks the URL’s domain name (or IP address) and file path separately, it will not find items that go across the two. For example, with the URL www.zyxel.com.tw/news/pressroom.php, the NBG4115 would find “tw” in the domain name (www.zyxel.com.tw). It would also find “news” in the file path (news/pressroom.php) but it would not find “tw/news”.14.2 FilterUse this screen to restrict web features, add keywords for blocking and designate a trusted computer.

User’s Guide 153CHAPTER 15Static Route15.1 OverviewThis chapter shows you how to configure static routes for your NBG4115.The NBG4115 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the NBG4115 send data to devices not reachable through the default gateway, use static routes.For example, the next figure shows a computer (A) connected to the NBG4115’s LAN interface. The NBG4115 routes most traffic from Ato the Internet through the NBG4115’s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN.Figure 77 Example of Static Routing Topology15.1.1 What You Can Do in this Chapter•Use the IP Static Route screen (Section 15.2 on page 154) to view existing static route rules.•Use the Static Route Setup screen (Section 15.2.1 on page 155) to add or edit a static route rule.WANR1R2AR3LANCompany Confidential

User’s Guide 157CHAPTER 16Bandwidth Management16.1 Overview This chapter contains information about configuring bandwidth management and editing rules.ZyXEL’s Bandwidth Management allows you to specify bandwidth management rules based on an application. In the figure below, uplink traffic goes from the LAN device (A) to the WAN device (B). Bandwidth management is applied before sending the packets out to the WAN. Downlink traffic comes back from the WAN device (B) to the LAN device (A). Bandwidth management is applied before sending the traffic out to LAN.Figure 80 Bandwidth ManagementYou can allocate specific amounts of bandwidth capacity (bandwidth budgets) to individual applications (like VoIP, Web, FTP, and E-mail for example).16.1.1 What You Can Do in this Chapter•Use the General screen (Section 16.2 on page 158) to enable bandwidth management and assign uplink/downlink limits.•Use the Advanced screen (Section 16.3 on page 159) to configure bandwidth management rules for the pre-defined services and applications.16.1.2 What You Need To KnowThe following terms and concepts may help as you read through this chapter.ABCompany Confidential
Chapter 16Bandwidth ManagementUser’s Guide158Bandwidth LimitingYou can limit an application’s uplink or downlink bandwidth. This limit keeps the traffic from using up too much of the out-going interface’s bandwidth. This way you can make sure there is bandwidth for other applications. Use the following guidelines:•The sum of the bandwidth allotments that apply to the WAN interface (LAN to WAN, WLAN to WAN) must be less than or equal to the Uplink value that you configure in the Bandwidth ManagementGeneral screen. •The sum of the bandwidth allotments that apply to the LAN port (WAN to LAN, WAN to WLAN) must be less than or equal to the Downlink value that you configure in the Bandwidth ManagementGeneral screen.16.2 General Use this screen to enable bandwidth management and assign uplink/downlink limits. You can use either one of the following types:•Priority Queue. Enable bandwidth management to give uplink traffic that matches a bandwidth rule priority over traffic that does not match a bandwidth rule. (This type does not apply to downlink traffic.) •Bandwidth Allocation. Enabling bandwidth management also allows you to control the maximum or minimum amounts of bandwidth that can be used by traffic that matches a bandwidth rule.Note: You cannot apply both bandwidth management types at the same time.Click Management> Bandwidth MGMT to open the bandwidth management General screen.Figure 81 Management > Bandwidth MGMT > GeneralCompany Confidential

A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.18.1.1 What You Can Do in this ChapterUse the UPnP screen (Section 18.2 on page 170) to enable UPnP on the NBG4115.18.1.2 What You Need to KnowThe following terms and concepts may help as you read through this chapter.How do I know if I'm using UPnP? UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. NAT TraversalUPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:•Dynamic port mappingCompany Confidential
Chapter 18UPnPUser’s Guide170•Learning public IP addresses•Assigning lease times to mappingsWindows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT.Cautions with UPnPThe automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the NBG4115 allows multicast messages on the LAN only.All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 18.2 GeneralUse this screen to enable UPnP.

User’s Guide 223APPENDIX C IP Addresses and SubnettingThis appendix introduces IP addresses and subnet masks. IP 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 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.Introduction to IP AddressesOne part of the IP address is the network number, and the other part is the host ID. In the same way that houses on a street share a common street name, the hosts on a network share a common network number. Similarly, as each house has its own house number, each host on the network has its own unique identifying number - the host ID. Routers use the network number to send packets to the correct network, while the host ID determines to which host on the network the packets are delivered.StructureAn IP address is made up of four parts, written in dotted decimal notation (for example, 192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal.Company Confidential
Appendix CIP Addresses and SubnettingUser’s Guide224The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID.Figure 124 Network Number and Host IDHow much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet MasksA subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”.A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit in the IP address is part of the host ID. The following example shows a subnet mask identifying the network number (in bold text) and host ID of an IP address (192.168.1.2 in decimal).Table 70 Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)IP Address (Binary)11000000101010000000000100000010Subnet Mask (Binary) 111111111111111111111111 00000000Company Confidential
Appendix CIP Addresses and SubnettingUser’s Guide 225By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes.Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Network SizeThe size of the network number determines the maximum number of possible hosts you can have on your network. The larger the number of network number bits, the smaller the number of remaining host ID bits. An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that network (192.168.1.255 with a 24-bit subnet mask, for example).Network Number 110000001010100000000001Host ID00000010Table 71 Subnet MasksBINARYDECIMAL1STOCTET 2NDOCTET 3RDOCTET 4THOCTET8-bit mask 11111111 00000000 00000000 00000000 255.0.0.016-bitmask 11111111 11111111 00000000 00000000 255.255.0.024-bitmask 11111111 11111111 11111111 00000000 255.255.255.029-bitmask 11111111 11111111 11111111 11111000 255.255.255.248Table 70 Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)Company Confidential
Appendix CIP Addresses and SubnettingUser’s Guide226As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:NotationSince the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations.

Appendix CIP Addresses and SubnettingUser’s Guide 227SubnettingYou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.The following figure shows the company network before subnetting. Figure 125 Subnetting Example: Before SubnettingYou can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25).The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25. Company Confidential
Appendix CIP Addresses and SubnettingUser’s Guide228The following figure shows the company network after subnetting. There are now two sub-networks, A and B.Figure 126 Subnetting Example: After SubnettingIn a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.Example: Four Subnets The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets. Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192. Company Confidential

Appendix CIP Addresses and SubnettingUser’s Guide 231The following table is a summary for subnet planning on a network with a 16-bit network number. Configuring IP AddressesWhere 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. 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. You must also enable Network Address Translation (NAT) on the NBG4115. Once you have decided on the network number, pick an IP address for your NBG4115 that is easy to remember (for instance, 192.168.1.1) 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.

If your networks are isolated from the Internet (running only between two branch offices, for example) 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 — 192.168.255.255You 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.

User’s Guide 251APPENDIX E Wireless LANsWireless LAN TopologiesThis section discusses ad-hoc and infrastructure wireless LAN topologies.Ad-hoc Wireless LAN ConfigurationThe simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN. Figure 150 Peer-to-Peer Communication in an Ad-hoc NetworkBSSA Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate Company Confidential
Appendix EWireless LANsUser’s Guide252with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.Figure 151 Basic Service SetESSAn Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS).This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood. Company Confidential
Appendix EWireless LANsUser’s Guide 253An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate.Figure 152 Infrastructure WLANChannelA channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.RTS/CTSA hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations (STA) are within range of the access point (AP) or Company Confidential
Appendix EWireless LANsUser’s Guide254wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other. Figure 153 RTS/CTSWhen station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked.When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission.Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.Company Confidential
Appendix EWireless LANsUser’s Guide 255Fragmentation ThresholdAFragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames.A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.Preamble TypeA preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short.Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless stations support it. Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless stations support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the AP and the wireless stations and to provide more reliable communication in ‘noisy’ networks. Select Dynamic to have the AP automatically use short preamble when all wireless stations support it, otherwise the AP uses long preamble.Note: The AP and the wireless stations MUSTuse the same preamble mode in order to communicate.IEEE 802.11g Wireless LANIEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has Company Confidential
Appendix EWireless LANsUser’s Guide256several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:IEEE 802.1xIn June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:•User based identification that allows for roaming.•Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. •Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations. RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:•Authentication Determines the identity of the users.•AuthorizationDetermines the network services available to authenticated users once they are connected to the network.•AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless station and the network RADIUS server.

Appendix EWireless LANsUser’s Guide 257Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:•Access-RequestSent by an access point requesting authentication.•Access-RejectSent by a RADIUS server rejecting access.•Access-AcceptSent by a RADIUS server allowing access. •Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:•Accounting-RequestSent by the access point requesting accounting.•Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5,EAP-TLS,EAP-TTLS,PEAP and LEAP.The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information.EAP-MD5 (Message-Digest Algorithm 5)MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. Company Confidential
Appendix EWireless LANsUser’s Guide258However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. EAP-TLS (Transport Layer Security)With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP)Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.LEAPLEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key ExchangeThe AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.Company Confidential
Appendix EWireless LANsUser’s Guide 259If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.Note: EAP-MD5 cannot be used with dynamic WEP key exchangeFor added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.WPA(2)Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication. EncryptionBoth WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption. Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.Table 82 Comparison of EAP Authentication TypesEAP-MD5 EAP-TLS EAP-TTLS PEAP LEAPMutual Authentication No Yes Yes Yes YesCertificate – Client No Yes Optional Optional NoCertificate – Server No Yes Yes Yes NoDynamic Key Exchange No Yes Yes Yes YesCredential Integrity None Strong Strong Strong ModerateDeployment Difficulty Easy Hard Moderate Moderate ModerateClient Identity Protection No No Yes Yes NoCompany Confidential
Appendix EWireless LANsUser’s Guide260TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically.WPA2 AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael.The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), TKIP makes it much more difficult to decode data on a Wi-Fi network than WEP, making it difficult for an intruder to break into the network. The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it's still an improvement over WEP as it employs an easier-to-use, consistent, single, alphanumeric password. User AuthenticationWPA or WPA2 applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2 -PSK (WPA2 -Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.Company Confidential
Appendix EWireless LANsUser’s Guide 26124.6.2 WPA(2)-PSK Application ExampleA WPA(2)-PSK application looks as follows.1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols).2The AP checks each wireless client's password and (only) allows it to join the network if the password matches.3The AP derives and distributes keys to the wireless clients.4The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them.Figure 154 WPA(2)-PSK Authentication24.6.3 WPA(2) with RADIUS Application ExampleYou need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.1The AP passes the wireless client's authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
