VMG1312-T10C Users Guide PART I Users Guide 13 14 CHAPTER 1 Introduction 1.1 Overview This VDSL2 router allows super-fast, secure Internet access over analog (POTS) telephone lines. It supports both Packet Transfer Mode (PTM) and Asynchronous Transfer Mode (ATM). You can have ADSL (ADSL, ADSL2, ADSL2+) connections or VDSL2 connections. The Device integrates DSL and NAT for ease of installation and high-speed, shared Internet access. It also provides a complete security solution with a robust firewall and content filtering. The product name format indicates the following:

H denotes an integrated 4-port hub (switch). N denotes IEEE 802.11n wireless networking support. U denotes a USB port used to set up a 3G WAN connection via a 3G wireless card or share files via a USB memory stick or a USB hard drive. The Device can also function as a print server with an USB printer connected. Only use firmware for your Devices specific model. Refer to the label on the bottom of your Device. 1.2 Ways to Manage the Device Use any of the following methods to manage the Device. Web Configurator. Use a (supported) web browser to manage the Device. FTP for firmware upgrades and configuration backup/restore. TR-069. This auto-configuration server remotely configures your device. 1.3 Good Habits for Managing the Device Do the following things regularly to make the Device more secure and to manage the Device more effectively. Change the password. Use a password thats 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. VMG1312-T10C Users Guide 15 Chapter 1 Introduction Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the Device to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the Device. You could simply restore your last configuration. 1.4 Applications for the Device Here are some example uses for the Device. 1.4.1 Internet Access Your Device provides shared Internet access by connecting the DSL port to the DSL or MODEM jack on a splitter or your telephone jack. Computers can connect to the Devices LAN ports (or wirelessly). Figure 1 Devices Router Features LAN DSL Configure firewall and filtering features on the Device for secure Internet access. Set the firewall to allow responses from the Internet for traffic initiated from your network and block traffic initiated from the Internet. This blocks probes from the outside to your network, but lets you safely browse the Internet and download files. Use the filtering feature to block access to specific web sites or Internet applications such as MSN or Yahoo Messenger. You can also configure IP/MAC filtering rules for incoming or outgoing traffic. Use QoS to efficiently manage traffic on your network by giving priority to certain types of traffic and/or to particular computers. For example, you could make sure that the Device gives voice over Internet calls high priority, and/or limit bandwidth devoted to the bosss excessive file downloading. 1.5 Wireless Access The Device serves as a wireless Access Point (AP) to let wireless clients such as notebook computers, smart phones, and tablets connect to the Internet without Ethernet cables. 16 VMG1312-T10C Users Guide Configure your wireless network through the Web Configurator, or the WPS button. Figure 2 Wireless Access Example Chapter 1 Introduction 1.5.1 Using the WLAN/WPS Button By default, the Devices wireless network is enabled. To turn it off, simply press the WPS/WLAN button on top of the Device for over 5 seconds. The WLAN/WPS LED turns off. Use the WLAN/WPS button to quickly set up a secure wireless connection between the Device and a WPS-compatible client by adding one device at a time. To activate WPS:

1 With the POWER LED on steady, press the WLAN/WPS button for 1 second and release it. 2 Within two minutes, press the WPS button on a WPS-enabled client within range of the Device. The WPS/WLAN LED should flash while the Device sets up a WPS connection with the client. 3 The WPS/WLAN LED shines green for a successful connection. VMG1312-T10C Users Guide 17 Chapter 1 Introduction 1.6 The RESET Button If you forget your password or cannot access the web configurator, use the RESET button at the back of the device to reload the factory-default configuration file. This means that you will lose all configurations that you had previously and the user name and password will be reset to the default. 1.6.1 Using the Reset Button With the POWER LED on steady, press the RESET button for ten seconds or until the POWER LED begins to blink and then release it. When the POWER LED begins to blink, the defaults have been restored and the device restarts. 1.7 LEDs (Lights) The following graphic displays the labels of the LEDs.

VMG1312-T10C Users Guide 33 Chapter 4 Connection Status and System Info 34 VMG1312-T10C Users Guide CHAPTER 5 WAN Setup 5.1 Overview This chapter describes how to configure WAN settings from the WAN screens. Use these screens to configure your Device for Internet access. A WAN (Wide Area Network) connection connects 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 15 LAN and WAN LAN WAN 3G (third generation) standards for the sending and receiving of voice, video, and data in a mobile environment. You can attach a 3G wireless adapter to the USB port and set the Device to use this 3G connection as your WAN or a backup when the wired WAN connection fails. Figure 16 3G WAN Connection 5.1.1 What You Can Do in the WAN Screens Use the Internet Connection screen (Section 5.2 on page 38) to configure the WAN settings on the Device for Internet access. VMG1312-T10C Users Guide 35 Chapter 5 WAN Setup Use the More Connections screen (Section 5.3 on page 44) to set up additional Internet access connections. Use the 3G Backup screen to configure 3G WAN connection (Section 5.4 on page 50). 5.1.2 What You Need to Know About WAN Encapsulation Method Encapsulation includes 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 PPPoA, they should also provide a username and password (and service name) for user authentication. WAN IP Address The Device uses its WAN IP address to connect to the Internet and communicate with devices in other networks. It can be static (fixed) or dynamically assigned by the ISP when the Device connects to 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). Multicast Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just one. IGMP Devices use the IGMP (Internet Group Management Protocol) network-layer protocol to establish membership in a multicast group - it does not carry user data. IGMP versions 2 and 3 offer improvements over the widely-used version 1. IPv6 IPv6 (Internet Protocol version 6) provides increased IP address space and enhanced features in comparison to IPv4. The Device supports IPv4/IPv6 dual stack and can connect to IPv4 and IPv6 networks. IPv6 Rapid Deployment Use IPv6 Rapid Deployment (6rd) when the local network uses IPv6 and the ISP has an IPv4 network. When the Device has an IPv4 WAN address and you set IPv6/IPv4 Dual Stack to IPv4, you can enable 6rd to encapsulate IPv6 packets in IPv4 packets to cross the ISPs IPv4 network. The Device generates a global IPv6 prefix from its IPv4 WAN address and tunnels IPv6 traffic to the ISPs Border Relay router (BR in the figure) to connect to the native IPv6 Internet. The local 36 VMG1312-T10C Users Guide Chapter 5 WAN Setup network can also use IPv4 services. The Device uses its configured IPv4 WAN IP to route IPv4 traffic to the IPv4 Internet.

When the Device has an IPv6 WAN address and you set IPv6/IPv4 Dual Stack to IPv6, you can enable Dual Stack Lite to use IPv4 computers and services. The Device tunnels IPv4 packets inside IPv6 encapsulation packets to the ISPs Address Family Transition Router (AFTR in the graphic) to connect to the IPv4 Internet. The local network can also use IPv6 services. The VDSL Router uses its configured IPv6 WAN IP to route IPv6 traffic to the IPv6 Internet. Figure 18 Dual Stack Lite LAN

Click Cancel to return to the previous configuration. 5.5 WAN Technical Reference This section provides some technical background information about the topics covered in this chapter. 5.5.1 Encapsulation Be sure to use the encapsulation method required by your ISP. The Device supports the following methods. 5.5.1.1 ENET ENCAP The Device only implements the MAC Encapsulated Routing Link Protocol (ENET ENCAP) with the IP network protocol. IP packets get routed between the Ethernet interface and the WAN interface and then formatted to work in a bridged environment. For instance, it encapsulates routed Ethernet 52 VMG1312-T10C Users Guide Chapter 5 WAN Setup frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the Gateway IP Address field in the wizard or WAN screen. You can get this information from your ISP. 5.5.1.2 PPP over Ethernet The Device supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE specifies how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option provides a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example RADIUS). PPPoE lets 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 Device (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the Device does that part of the task. Furthermore, with NAT, all of the LANs computers will have access. 5.5.1.3 PPPoA PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The Device encapsulates the PPP session based on RFC 1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Providers (ISP) DSLAM (Digital Subscriber Line (DSL) Access Multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP. 5.5.1.4 RFC 1483 RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5

(AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit

(LLC-based multiplexing) and the second method assumes a separate ATM virtual circuit (VC-based multiplexing) carries each protocol. Please refer to RFC 1483 for more detailed information. 5.5.2 Multiplexing There are two conventions to identify what protocols the virtual circuit (VC) carries. Use the multiplexing method required by your ISP. VC-based Multiplexing In this case, by prior mutual agreement, each protocol uses a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical. VMG1312-T10C Users Guide 53 Chapter 5 WAN Setup LLC-based Multiplexing In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs. 5.5.3 VPI and VCI Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information. 5.5.4 IP Address Assignment A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP gateway. IP Assignment with PPPoA or PPPoE Encapsulation If you have a dynamic IP, then the IP Address and Gateway IP Address fields are not applicable

(N/A). If you have a Static IP Address assigned by your ISP, then they should also assign you a Subnet Mask and a Gateway IP Address. IP Assignment with RFC 1483 Encapsulation In this case the IP address assignment must be static. IP Assignment with ENET ENCAP Encapsulation In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and Gateway IP Address fields as supplied by your ISP. However for a dynamic IP, the Device acts as a DHCP client on the WAN port and so the IP Address and Gateway IP Address fields are not applicable (N/A) as the DHCP server assigns them to the Device. 54 VMG1312-T10C Users Guide CHAPTER 6 Wireless 6.1 Overview This chapter describes the Devices Network Setting > Wireless screens. Use these screens to set up your Devices wireless connection. 6.1.1 What You Can Do in this Chapter Use the General screen to enable the wireless LAN, enter the SSID and select the wireless security mode (Section 6.2 on page 57). Use the More AP screen to set up multiple wireless networks on your Device (Section 6.3 on page 63). Use the MAC Authentication screen to allow or deny wireless clients based on their MAC addresses from connecting to the Device (Section 6.4 on page 66). Use the WPS screen to enable or disable WPS, view or generate a security PIN (Personal Identification Number) (Section 6.5 on page 67). Use the WDS screen (see Section 6.6 on page 69) to set up a Wireless Distribution System, in which the Device acts as a bridge with other access points. Use the WMM screen to enable Wi-Fi MultiMedia (WMM) to ensure quality of service in wireless networks for multimedia applications (Section 6.7 on page 70). Use the Scheduling screen to schedule a time period for the wireless LAN to operate each day

(Section 6.8 on page 71). Use the Advanced screen to configure advanced wireless features (Section 6.9 on page 73). You dont necessarily need to use all these screens to set up your wireless connection. 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 Wireless Network Overview Wireless networks consist of wireless clients, access points and bridges. A wireless client is a radio connected to a users 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 networks 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. VMG1312-T10C Users Guide 55 Chapter 6 Wireless 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. The following figure provides an example of a wireless network. Figure 25 Example of a Wireless Network The wireless network is the part in the blue circle. In this wireless network, devices A and B use the access point (AP) to interact with the other devices (such as the printer) or with the Internet. Your Device is the AP. Every wireless network must follow these basic guidelines. Every device in the same wireless network must use the same SSID. The SSID is the name of the wireless network. It stands for Service Set IDentifier. If two wireless networks overlap, they should use a different channel. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. Every device 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. Radio Channels In the radio spectrum, there are certain frequency bands allocated for unlicensed, civilian use. For the purposes of wireless networking, these bands are divided into numerous channels. This allows a variety of networks to exist in the same place without interfering with one another. When you create a network, you must select a channel to use. 56 VMG1312-T10C Users Guide Chapter 6 Wireless Since the available unlicensed spectrum varies from one country to another, the number of available channels also varies. 6.1.3 Before You Begin Before you start using these screens, ask yourself the following questions. See Section 6.10 on page 74 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. What advanced options do you want to configure, if any? If you want to configure advanced options, ensure that you know precisely what you want to do. If you do not want to configure advanced options, leave them alone. 6.2 Wireless General Screen Use this screen to enable the Wireless LAN, enter the SSID and select the wireless security mode. Note: If you are configuring the Device from a computer connected to the wireless LAN and you change the Devices SSID 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 Devices new settings.

Note: If you do not enable any wireless security on your Device, your network is accessible to any wireless networking device that is within range. Figure 27 Wireless > General: No Security The following table describes the labels in this screen. Table 10 Wireless > General: No Security LABEL Security Level DESCRIPTION Choose No Security from the sliding bar. 6.2.2 Basic (Static WEP/Shared WEP Encryption) WEP encryption scrambles the data transmitted between the wireless stations and the access points

(AP) to keep network communications private. Both the wireless stations and the access points must use the same WEP key. VMG1312-T10C Users Guide 59 Chapter 6 Wireless There are two types of WEP authentication namely, Open System (Static WEP) and Shared Key

(Shared WEP). Open system 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 key 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. In order to configure and enable WEP encryption, click Network Settings > Wireless to display the General screen. Select Basic as the security level. Then select Static WEP or Shared WEP from the Security Mode list. Figure 28 Wireless > General: Basic (Static WEP/Shared WEP) The following table describes the labels in this screen. Table 11 Wireless > General: Basic (Static WEP/Shared WEP) LABEL Security Level DESCRIPTION Select Basic to enable WEP data encryption. Generate password automatically Select this option to have the Device automatically generate a password. The password field will not be configurable when you select this option. Password 1~4 The password (WEP key) is used to encrypt data. Both the Device and the wireless stations must use the same password (WEP key) for data transmission. If you chose 64-bit WEP, then enter any 5 ASCII characters or 10 hexadecimal characters ("0-9", "A-F"). If you chose 128-bit WEP, then enter 13 ASCII characters or 26 hexadecimal characters ("0-9", "A-F"). WEP Encryption Select 64-bits or 128-bits. This dictates the length of the security key that the network is going to use. 60 VMG1312-T10C Users Guide Chapter 6 Wireless 6.2.3 More Secure (WPA(2)-PSK) The WPA-PSK security mode provides both improved data encryption and user authentication over WEP. Using a Pre-Shared Key (PSK), both the Device and the connecting client share a common password in order to validate the connection. This type of encryption, while robust, is not as strong as WPA, WPA2 or even WPA2-PSK. The WPA2-PSK security mode is a newer, more robust version of the WPA encryption standard. It offers slightly better security, although the use of PSK makes it less robust than it could be. Click Network Settings > Wireless to display the General screen. Select More Secure as the security level. Then select WPA-PSK or WPA2-PSK from the Security Mode list. Figure 29 Wireless > General: More Secure: WPA(2)-PSK The following table describes the labels in this screen.

Pre-Shared Key The encryption mechanisms used for WPA/WPA2 and WPA-PSK/WPA2-PSK are the same. The only difference between the two is that WPA-PSK/WPA2-PSK uses a simple common password, instead of user-specific credentials. Type a pre-shared key from 8 to 63 case-sensitive ASCII characters or 64 hexidecimal digits. more.../hide more Click more... to show more fields in this section. Click hide more to hide them. WPA-PSK Compatible This appears when you choose WPA-PSK2 as the Security Mode. Enable this to allow wireless devices using WPA-PSK security mode to connect to your Device. The Device supports WPA-PSK and WPA2-PSK simultaneously. VMG1312-T10C Users Guide 61 Chapter 6 Wireless Table 12 Wireless > General: WPA(2)-PSK (continued) LABEL Group Key Update Timer DESCRIPTION The Group Key Update Timer is the rate at which the RADIUS server sends a new group key out to all clients. Encryption If the security mode is WPA-PSK, the encryption mode is set to TKIP to enable Temporal Key Integrity Protocol (TKIP) security on your wireless network. If the security mode is WPA-PSK2 and WPA-PSK Compatible is disabled, the encryption mode is set to AES to enable Advanced Encryption System (AES) security on your wireless network. AES provides superior security to TKIP. If the security mode is WPA-PSK2 and WPA-PSK Compatible is enabled, the encryption mode is set to TKIPAES MIX to allow both TKIP and AES types of security in your wireless network. 6.2.4 WPA(2) Authentication The WPA2 security mode is currently the most robust form of encryption for wireless networks. It requires a RADIUS server to authenticate user credentials and is a full implementation the security protocol. Use this security option for maximum protection of your network. However, it is the least backwards compatible with older devices. The WPA security mode is a security subset of WPA2. It requires the presence of a RADIUS server on your network in order to validate user credentials. This encryption standard is slightly older than WPA2 and therefore is more compatible with older devices. Click Network Settings > Wireless to display the General screen. Select More Secure as the security level. Then select WPA or WPA2 from the Security Mode list.

Table 23 Additional Wireless Terms DESCRIPTION TERM In a wireless network which covers a large area, wireless devices are RTS/CTS Threshold sometimes not aware of each others 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 Device. 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 Device. 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 Device does, it cannot communicate with the Device. Preamble Authentication The process of verifying whether a wireless device is allowed to use the wireless network. 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. 6.10.2 Wireless Security Overview By their nature, radio communications are simple to intercept. For wireless data networks, this means that anyone within range of a wireless network without security can not only read the data passing over the airwaves, but also join the network. Once an unauthorized person has access to the network, he or she can steal information or introduce malware (malicious software) intended to compromise the network. For these reasons, a variety of security systems have been developed to 74 VMG1312-T10C Users Guide Chapter 6 Wireless ensure that only authorized people can use a wireless data network, or understand the data carried on it. These security standards do two things. First, they authenticate. This means that only people presenting the right credentials (often a username and password, or a key phrase) can access the network. Second, they encrypt. This means that the information sent over the air is encoded. Only people with the code key can understand the information, and only people who have been authenticated are given the code key. These security standards vary in effectiveness. Some can be broken, such as the old Wired Equivalent Protocol (WEP). Using WEP is better than using no security at all, but it will not keep a determined attacker out. Other security standards are secure in themselves but can be broken if a user does not use them properly. For example, the WPA-PSK security standard is very secure if you use a long key which is difficult for an attackers software to guess - for example, a twenty-letter long string of apparently random numbers and letters - but it is not very secure if you use a short key which is very easy to guess - for example, a three-letter word from the dictionary. Because of the damage that can be done by a malicious attacker, its not just people who have sensitive information on their network who should use security. Everybody who uses any wireless network should ensure that effective security is in place. A good way to come up with effective security keys, passwords and so on is to use obscure information that you personally will easily remember, and to enter it in a way that appears random and does not include real words. For example, if your mother owns a 1970 Dodge Challenger and her favorite movie is Vanishing Point (which you know was made in 1971) you could use 70dodchal71vanpoi as your security key. The following sections introduce different types of wireless security you can set up in the wireless network. 6.10.2.1 SSID Normally, the Device acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the Device 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. 6.10.2.2 User Authentication Authentication 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 using 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. VMG1312-T10C Users Guide 75 Chapter 6 Wireless 6.10.2.3 Encryption Wireless 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 authentication. (See Section 6.10.2.2 on page 75 for information about this.) Table 24 Types of Encryption for Each Type of Authentication Weakest NO AUTHENTICATION No Security RADIUS SERVER WPA Static WEP WPA-PSK Strongest WPA2-PSK WPA2 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 Device 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 Device, 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 Device. 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. 6.10.3 Signal Problems Because wireless networks are radio networks, their signals are subject to limitations of distance, interference and absorption. Problems with distance occur when the two radios are too far apart. Problems with interference occur when other radio waves interrupt the data signal. Interference may come from other radio transmissions, such as military or air traffic control communications, or from machines that are coincidental emitters such as electric motors or microwaves. Problems with absorption occur when physical objects (such as thick walls) are between the two radios, muffling the signal. 76 VMG1312-T10C Users Guide Chapter 6 Wireless 6.10.4 BSS A 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 traffic blocking is disabled, wireless station A and B can access the wired network and communicate with each other. When Intra-BSS traffic blocking is enabled, wireless station A and B can still access the wired network but cannot communicate with each other. Figure 41 Basic Service set 6.10.5 MBSSID Traditionally, you need to use different APs to configure different Basic Service Sets (BSSs). As well as the cost of buying extra APs, there is also the possibility of channel interference. The Devices MBSSID (Multiple Basic Service Set IDentifier) function allows you to use one access point to provide several BSSs simultaneously. You can then assign varying QoS priorities and/or security modes to different SSIDs. Wireless devices can use different BSSIDs to associate with the same AP. 6.10.5.1 Notes on Multiple BSSs A maximum of eight BSSs are allowed on one AP simultaneously. You must use different keys for different BSSs. If two wireless devices have different BSSIDs

(they are in different BSSs), but have the same keys, they may hear each others communications (but not communicate with each other). MBSSID should not replace but rather be used in conjunction with 802.1x security. VMG1312-T10C Users Guide 77 Chapter 6 Wireless 6.10.6 Wireless Distribution System (WDS) The Device can act as a wireless network bridge and establish WDS (Wireless Distribution System) links with other APs. You need to know the MAC addresses of the APs you want to link to. Once the security settings of peer sides match one another, the connection between devices is made. At the time of writing, WDS security is not compatible with all access points. Refer to your other access points documentation for details. The following figure illustrates how WDS link works between APs. Notebook computer A is a wireless client connecting to access point AP 1. AP 1 has no wired Internet connection, but it can establish a WDS link with access point AP 2, which has a wired Internet connection. When AP 1 has a WDS link with AP 2, the notebook computer can access the Internet through AP 2. Figure 42 WDS Link Example A WDS AP 1 AP 2 78 VMG1312-T10C Users Guide CHAPTER 7 Home Networking 7.1 Overview A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is usually located in one immediate area such as a building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses. LAN WAN 7.1.1 What You Can Do in this Chapter Use the LAN Setup screen to set the LAN IP address, subnet mask, and DHCP settings (Section 7.2 on page 88). Use the Static DHCP screen to assign IP addresses on the LAN to specific individual computers based on their MAC Addresses (Section 7.3 on page 90). Use the IP Alias screen (Section 7.4 on page 91) to configure another logical network in the physical LAN network. Use the UPnP screen to enable UPnP (Section 7.5 on page 92). Use the UPnP Rule screen to Use the IPv6 LAN Setup screen (Section 7.7 on page 93) to configure the IPv6 settings on your Devices LAN interface. Use the File Sharing screen to enable file-sharing server (Section 7.8 on page 97). Use the Printer Server screen to enable the print server (Section 7.9 on page 100). 7.1.2 What You Need To Know The following terms and concepts may help as you read this chapter. VMG1312-T10C Users Guide 85 Chapter 7 Home Networking 7.1.2.1 About LAN IP Address Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number. This is known as an Internet Protocol address. Subnet Mask The 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 you entered. You don't need to change the subnet mask computed by the Device unless you are instructed to do otherwise. DHCP DHCP (Dynamic Host Configuration Protocol) allows clients to obtain TCP/IP configuration at start-

up from a server. This Device has a built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. DNS DNS (Domain Name System) maps 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 DNS server addresses you enter when you set up DHCP are passed to the client machines along with the assigned IP address and subnet mask. 7.1.2.2 About UPnP 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. Cautions with UPnP The 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 Device 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. UPnP and ZyXEL ZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device (IGD) 1.0. 86 VMG1312-T10C Users Guide See Section 7.11 on page 105 for examples of installing and using UPnP. 7.1.2.3 About File Sharing Workgroup name Chapter 7 Home Networking This is the name given to a set of computers that are connected on a network and share resources such as a printer or files. Windows automatically assigns the workgroup name when you set up a network. Shares When settings are set to default, each USB device connected to the Device is given a folder, called a share. If a USB hard drive connected to the Device has more than one partition, then each partition will be allocated a share. You can also configure a share to be a sub-folder or file on the USB device. File Systems A file system is a way of storing and organizing files on your hard drive and storage device. Often different operating systems such as Windows or Linux have different file systems. The file sharing feature on your Device supports FAT16, FAT32, NTFS, EXT2, and EXT3. Common Internet File System The Device uses Common Internet File System (CIFS) protocol for its file sharing functions. CIFS compatible computers can access the USB file storage devices connected to the Device. CIFS protocol is supported on Microsoft Windows, Linux Samba and other operating systems (refer to your systems specifications for CIFS compatibility). 7.1.2.4 About Printer Server Print Server This is a computer or other device which manages one or more printers, and which sends print jobs to each printer from the computer itself or other devices. Operating System An operating system (OS) is the interface which helps you manage a computer. Common examples are Microsoft Windows, Mac OS or Linux. TCP/IP TCP/IP (Transmission Control Protocol/ Internet Protocol) is a set of communications protocols that most of the Internet runs on. VMG1312-T10C Users Guide 87 Chapter 7 Home Networking Port A port maps a network service such as http to a process running on your computer, such as a process run by your web browser. When traffic from the Internet is received on your computer, the port number is used to identify which process running on your computer it is intended for. Supported OSs Your operating system must support TCP/IP ports for printing and be compatible with the RAW (port 9100) protocol. The following OSs support Devices printer sharing feature. Microsoft Windows 95, Windows 98 SE (Second Edition), Windows Me, Windows NT 4.0, Windows 2000, Windows XP or Macintosh OS X. 7.2 The LAN Setup Screen Click Network Setting > Home Networking to open the LAN Setup screen.

Use this field to control how much routing information the VDSL Router sends and receives on the subnet. Select the RIP Direction from None, Both, IN Only and OUT Only. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a multicast group. The Device supports IGMP v1/IGMP v2/IGMP v3. Select None to disable it. IGMP Snooping Select Enabled to activate IGMP Snooping. This allows the Device to passively learn memberships in multicast groups. Otherwise, select Disabled to deactivate it. DHCP Server State DHCP IP Addressing Values IP Pool Starting Address Pool Size DNS Values DNS Server 1-2 Select Enable to have your Device assign IP addresses, an IP default gateway and DNS servers to LAN computers and other devices that are DHCP clients. If you select Disable, you need to manually configure the IP addresses of the computers and other devices on your LAN. When DHCP is used, the following fields need to be set. This field specifies the first of the contiguous addresses in the IP address pool. This field specifies the size, or count of the IP address pool. The Device supports DNS proxy by default. The Device sends out its own LAN IP address to the DHCP clients as the first DNS server address. DHCP clients use this first DNS server to send domain-name queries to the Device. The Device sends a response directly if it has a record of the domain-name to IP address mapping. If it does not, the Device queries an outside DNS server and relays the response to the DHCP client. Select From ISP if your ISP dynamically assigns DNS server information (and the Device's WAN IP address). Select DNS Proxy to have the DHCP clients use the Devices own LAN IP address. The Device works as a DNS relay. Select User-Defined if you have the IP address of a DNS server. Enter the DNS server's IP address in the field to the right.

LANs, WANs and the Device The actual physical connection determines whether the Device ports are LAN or WAN ports. There are two separate IP networks, one inside the LAN network and the other outside the WAN network as shown next. Figure 59 LAN and WAN IP Addresses LAN WAN DHCP Setup DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the Device as a DHCP server or disable it. When configured as a server, the Device provides the TCP/IP configuration for the clients. If you turn DHCP service off, you must have another DHCP server on your LAN, or else the computer must be manually configured. IP Pool Setup The Device is pre-configured with a pool of IP addresses for the DHCP clients (DHCP Pool). See the product specifications in the appendices. Do not assign static IP addresses from the DHCP pool to your LAN computers. VMG1312-T10C Users Guide 101 Chapter 7 Home Networking LAN TCP/IP The Device has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability. IP Address and Subnet Mask Similar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number. Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the Device. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network. Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your Device, but make sure that no other device on your network is using that IP address. The subnet mask specifies the network number portion of an IP address. Your Device will compute the subnet mask automatically based on the IP address that you entered. You don't need to change the subnet mask computed by the Device unless you are instructed to do otherwise. Private IP Addresses Every machine on the Internet must have a unique address. If your networks are isolated from the Internet, for example, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:

10.0.0.0 10.255.255.255 172.16.0.0 172.31.255.255 192.168.0.0 192.168.255.255 You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses. 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. 102 VMG1312-T10C Users Guide Chapter 7 Home Networking 7.11 Installing UPnP in Windows Example This section shows how to install UPnP in Windows Me and Windows XP.

To have the Device 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 Devices LAN interface. The Device routes most traffic from A to the Internet through the Devices 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.

Use these screens to set up your Device to use QoS for traffic management. Quality of Service (QoS) refers to both a networks ability to deliver data with minimum delay, and the networking methods used to control the use of bandwidth. QoS allows the Device to group and prioritize application traffic and fine-tune network performance. Without QoS, all traffic data is equally likely to be dropped when the network is congested. This can cause a reduction in network performance and make the network inadequate for time-critical application such as video-on-demand. The Device assigns each packet a priority and then queues the packet accordingly. Packets assigned a high priority are processed more quickly than those with low priority if there is congestion, allowing time-sensitive applications to flow more smoothly. Time-sensitive applications include both those that require a low level of latency (delay) and a low level of jitter (variations in delay) such as Internet gaming, and those for which jitter alone is a problem such as Internet radio or streaming video. 9.1.1 What You Can Do in this Chapter Use the General screen to enable QoS, set the bandwidth, and allow the Device to automatically assign priority to upstream traffic according to the IP precedence or packet length (Section 9.2 on page 120). Use the Queue Setup screen to configure QoS queue assignment (Section 9.3 on page 121). Use the Class Setup screen to set up classifiers to sort traffic into different flows and assign priority and define actions to be performed for a classified traffic flow (Section 9.4 on page 122). Use the Policer Setup screento add, edit or delete QoS policers (Section 9.5 on page 127). Use the Game List screen to to give priority to traffic for specific games (Section 9.6 on page 129). 9.1.2 What You Need to Know The following terms and concepts may help as you read this chapter. QoS versus Cos QoS is used to prioritize source-to-destination traffic flows. All packets in the same flow are given the same priority. CoS (class of service) is a way of managing traffic in a network by grouping similar types of traffic together and treating each type as a class. You can use CoS to give different priorities to different packet types. VMG1312-T10C Users Guide 119 Chapter 9 Quality of Service (QoS) CoS technologies includes DiffServ (Differentiated Services or DS). DiffServ is a new protocol and defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header. Tagging and Marking In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value ain a matched packet. When the packet passes through a compatible network, the networking device, such as a backbone switch, can provide specific treatment or service based on the tag or marker. 9.2 The QoS General Screen Use this screen to enable or disable QoS, set the bandwidth, and select to have the Device automatically assign priority to upstream traffic according to the IP precedence or packet length. Click Network Setting > QoS to open the General screen. Figure 79 Network Setting > QoS > General The following table describes the labels in this screen. Table 39 Network Setting > QoS > General LABEL Active QoS DESCRIPTION Select the check box to turn on QoS to improve your network performance. You can give priority to traffic that the Device forwards out through the WAN interface. Give high priority to voice and video to make them run more smoothly. Similarly, give low priority to many large file downloads so that they do not reduce the quality of other applications. Select how the Device assigns priorities to various upstream traffic flows. None: Disables auto priority mapping and has the Device put packets into the queues according to your classification rules. Traffic which does not match any of the classification rules is mapped into the default queue with the lowest priority. Traffic priority will be automatically assigned by Ethernet Priority: Automatically assign priority based on the IEEE 802.1p priority level. IP Precedence: Automatically assign priority based on the first three bits of the TOS field in the IP header. Packet Length: Automatically assign priority based on the packet size. Smaller packets get higher priority since control, signaling, VoIP, internet gaming, or other real-time packets are usually small while larger packets are usually best effort data packets like file transfers.

Name Enter the descriptive name of this policer. Meter Type This shows the traffic metering algorithm used in this policer. The Simple Token Bucket algorithm uses tokens in a bucket to control when traffic can be transmitted. Each token represents one byte. The algorithm allows bursts of up to b bytes which is also the bucket size. The Single Rate Three Color Marker (srTCM) is based on the token bucket filter and identifies packets by comparing them to the Committed Information Rate (CIR), the Committed Burst Size (CBS) and the Excess Burst Size (EBS). The Two Rate Three Color Marker (trTCM) is based on the token bucket filter and identifies packets by comparing them to the Committed Information Rate (CIR) and the Peak Information Rate (PIR). 128 VMG1312-T10C Users Guide Chapter 9 Quality of Service (QoS) Table 45 Policer Setup: Add/Edit (continued) LABEL Committed Rate DESCRIPTION Specify the committed rate. When the incoming traffic rate of the member QoS classes is less than the committed rate, the device applies the conforming action to the traffic. Committed Burst Size Specify the committed burst size for packet bursts. This must be equal to or less than the peak burst size (two rate three color) or excess burst size (single rate three color) if it is also configured. This is the maximum size of the (first) token bucket in a traffic metering algorithm. Conforming Action Specify what the Device does for packets within the committed rate and burst size (green-

marked packets). Pass: Send the packets without modification. DSCP Mark: Change the DSCP mark value of the packets. Enter the DSCP mark value to use. Non-

All packets in the flow are given the same priority. You can use CoS (class of service) to give different priorities to different packet types. DiffServ (Differentiated Services) 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. 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. DSCP 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. DSCP (6 bits) Unused (2 bits) 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 kinds of forwarding. Resources can then be allocated according to the DSCP values and the configured policies. 130 VMG1312-T10C Users Guide CHAPTER 10 Network Address Translation (NAT) 10.1 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 to a different IP address known within another network. 10.1.1 What You Can Do in this Chapter Use the General screen to limit the number of concurrent NAT sessions each client can use

(Section 10.2 on page 132). Use the Port Forwarding screen to configure forward incoming service requests to the servers on your local network (Section 10.3 on page 132). Use the DMZ screen to configure a default server (Section 10.4 on page 135). Use the ALG screen to enable or disable the SIP ALG (Section 10.5 on page 136). 10.1.2 What You Need To Know The following terms and concepts may help as you read this chapter. Inside/Outside and Global/Local Inside/outside denotes where a host is located relative to the Device, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/local 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. NAT In 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. VMG1312-T10C Users Guide 131 Chapter 10 Network Address Translation (NAT) Port Forwarding A port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make visible to the outside world even though NAT makes your whole inside network appear as a single computer to the outside world. Finding Out More See Section 10.6 on page 136 for advanced technical information on NAT. 10.2 The General Screen Use the General screen to limit the number of concurrent NAT sessions each client can use. Click Network Setting > NAT > General to display the following screen. Figure 87 Network Setting > NAT > General The following table describes the fields in this screen. Table 47 Network Setting > NAT > General LABEL Max NAT/

Firewall Session Per User DESCRIPTION Use this field to set a common limit to the number of concurrent NAT sessions each client computer can have. If only a few clients use peer to peer applications, you can raise this number to improve their performance. With heavy peer to peer application use, lower this number to ensure no single client uses too many of the available NAT sessions. Apply Cancel Click Apply to save your changes. Click Cancel to restore your previously saved settings. 10.3 The Port Forwarding Screen Use the Port Forwarding screen to forward incoming service requests to the servers 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 132 VMG1312-T10C Users Guide Chapter 10 Network Address Translation (NAT) specify a range of port numbers. You can allocate a server IP address that corresponds to a port or a range of ports. Please refer to RFC 1700 for further information about port numbers. 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. Configuring Servers Behind Port Forwarding (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 10.0.0.35 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 88 Multiple Servers Behind NAT Example A=10.0.0.33 LAN WAN B=10.0.0.34 10.0.0.1 IP Address assigned by ISP C=10.0.0.35 D=10.0.0.36 10.3.1 The Port Forwarding Screen Click Network Setting > NAT to open the Port Forwarding screen.

Global/local 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 that inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. Thus, 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. Table 52 NAT Definitions ITEM Inside DESCRIPTION This refers to the host on the LAN. Outside This refers to the host on the WAN. Local Global This refers to the packet address (source or destination) as the packet travels on the LAN. This refers to the packet address (source or destination) as the packet travels on the WAN. NAT never changes the IP address (either local or global) of an outside host. 10.6.2 What NAT Does In 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 Device 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). 10.6.3 How NAT Works Each 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 (and TCP or UDP source port numbers for Many-to-One and VMG1312-T10C Users Guide 137 Chapter 10 Network Address Translation (NAT) Many-to-Many Overload NAT mapping) in each packet and then forwards it to the Internet. The Device keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.

Bind WAN virtual channels (VCs) to Ethernet ports and WLANs to specify how traffic is forwarded. The Device forwards traffic from an Ethernet port only through the bound WAN virtual channel and vice versa. For ports not belonging to a port binding group, the Device forwards traffic according to the routing table. Additionally, specify ATM QoS settings for an ADSL virtual channel (PVC) to satisfy the bandwidth requirements of the traffic the PVC carries. For example, create two port binding groups on the device (R1) for two different WAN ATM PVC connections. The first PVC (PVC1) handles non time-

sensitive data traffic. The second PVC (PVC2) handle time sensitive Media-On-Demand (MOD) video traffic.

Figure 99 Network Setting > Port Binding: Disable 144 VMG1312-T10C Users Guide CHAPTER 12 Dynamic DNS 12.1 Overview This chapter discusses how to configure your Device to use Dynamic DNS. Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in applications such as NetMeeting and CU-SeeMe). 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. 12.1.1 What You Need To Know 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. If you have a private WAN IP address, then you cannot use Dynamic DNS.

Chapter 13 Filter VMG1312-T10C Users Guide 151 Chapter 13 Filter 152 VMG1312-T10C Users Guide CHAPTER 14 Firewall 14.1 Overview This chapter shows you how to enable the Device firewall. Use the firewall to protect your Device and network from attacks by hackers on the Internet and control access to it. The firewall:

allows traffic that originates from your LAN computers to go to all other networks. blocks traffic that originates on other networks from going to the LAN. blocks SYN and port scanner attacks. By default, the Device blocks DDOS, LAND and Ping of Death attacks whether the firewall is enabled or disabled. The following figure illustrates the 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 103 Default Firewall Action LAN WAN A 1 2 3 4 14.1.1 What You Can Do in the Firewall Screens Use the General screen (Section 14.2 on page 155) to select the firewall protection level on the Device. Use the Default Action screen (Section 14.3 on page 156) to set the default action that the firewall takes on packets that do not match any of the firewall rules. Use the Rules screen (Section 14.4 on page 157) to view the configured firewall rules and add, edit or remove a firewall rule. VMG1312-T10C Users Guide 153 Chapter 14 Firewall Use the Dos screen (Section 14.5 on page 162) to set the thresholds that the Device uses to determine when to start dropping sessions that do not become fully established (half-open sessions). 14.1.2 What You Need to Know About Firewall SYN Attack A SYN attack floods a targeted system with a series of SYN packets. Each packet causes the targeted system to issue a SYN-ACK response. While the targeted system waits for the ACK that follows the SYN-ACK, it queues up all outstanding SYN-ACK responses on a backlog queue. SYN-

ACKs are moved off the queue only when an ACK comes back or when an internal timer terminates the three-way handshake. Once the queue is full, the system will ignore all incoming SYN requests, making the system unavailable for legitimate users. DoS Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the Internet. Their goal is not to steal information, but to disable a device or network so users no longer have access to network resources. The Device is pre-configured to automatically detect and thwart all known DoS attacks. DDoS A Distributed DoS (DDoS) attack is one in which multiple compromised systems attack a single target, thereby causing denial of service for users of the targeted system. LAND Attack In a Local Area Network Denial (LAND) attack, hackers flood SYN packets into the network with a spoofed source IP address of the target system. This makes it appear as if the host computer sent the packets to itself, making the system unavailable while the target system tries to respond to itself. Ping of Death Ping of Death uses a "ping" utility to create and send an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. This may cause systems to crash, hang or reboot. SPI Stateful Packet Inspection (SPI) tracks each connection crossing the firewall and makes sure it is valid. Filtering decisions are based not only on rules but also context. For example, traffic from the WAN may only be allowed to cross the firewall in response to a request from the LAN. RFC 4890 SPEC Traffic RFC 4890 specifies the filtering policies for ICMPv6 messages. This is important for protecting against security threats including DoS, probing, redirection attacks and renumbering attacks that 154 VMG1312-T10C Users Guide Chapter 14 Firewall can be carried out through ICMPv6. Since ICMPv6 error messages are critical for establishing and maintaining communications, filtering policy focuses on ICMPv6 informational messages. Anti-Probing If an outside user attempts to probe an unsupported port on your Device, an ICMP response packet is automatically returned. This allows the outside user to know the Device exists. The Device supports anti-probing, which prevents the ICMP response packet from being sent. This keeps outsiders from discovering your Device when unsupported ports are probed. ICMP Internet Control Message Protocol (ICMP) is a message control and error-reporting protocol between a host server and a gateway to the Internet. ICMP uses Internet Protocol (IP) datagrams, but the messages are processed by the TCP/IP software and directly apparent to the application user. DoS Thresholds For DoS attacks, the Device uses thresholds to determine when to drop sessions that do not become fully established. These thresholds apply globally to all sessions. You can use the default threshold values, or you can change them to values more suitable to your security requirements. 14.2 Firewall General Screen Use this screen to select the firewall protection level on the Device.

The Device will drop sessions that surpass DESCRIPTION Apply Cancel Advanced maximum thresholds. Click this to save your changes. Click this to restore your previously saved settings. Click this to go to a screen to specify maximum thresholds at which the Device will start dropping sessions. 14.5.1 The DoS Advanced Screen For DoS attacks, the Device uses thresholds to determine when to start dropping sessions that do not become fully established (half-open sessions). These thresholds apply globally to all sessions. For TCP, half-open means that the session has not reached the established state-the TCP three-way handshake has not yet been completed. Under normal circumstances, the application that initiates a session sends a SYN (synchronize) packet to the receiving server. The receiver sends back an ACK

(acknowledgment) packet and its own SYN, and then the initiator responds with an ACK

(acknowledgment). After this handshake, a connection is established. Figure 111 Three-Way Handshake For UDP, half-open means that the firewall has detected no return traffic. An unusually high number

(or arrival rate) of half-open sessions could indicate a DOS attack. 14.5.1.1 Threshold Values If everything is working properly, you probably do not need to change the threshold settings as the default threshold values should work for most small offices. Tune these parameters when you believe the Device has been receiving DoS attacks that are not recorded in the logs or the logs show that the Device is classifying normal traffic as DoS attacks. Factors influencing choices for threshold values are:

1 2 3 The maximum number of opened sessions. The minimum capacity of server backlog in your LAN network. The CPU power of servers in your LAN network. VMG1312-T10C Users Guide 163 Chapter 14 Firewall 4 Network bandwidth. 5 Type of traffic for certain servers. Reduce the threshold values if your network is slower than average for any of these factors

(especially if you have servers that are slow or handle many tasks and are often busy). If you often use P2P applications such as file sharing with eMule or eDonkey, its recommended that you increase the threshold values since lots of sessions will be established during a small period of time and the Device may classify them as DoS attacks. 14.5.2 Configuring Firewall Thresholds Click Security > Firewall > DoS > Advanced to display the following screen.

Chapter 14 Firewall 14.6 Firewall Technical Reference This section provides some technical background information about the topics covered in this chapter. 14.6.1 Firewall Rules Overview Your customized rules take precedence and override the Devices default settings. The Device checks the source IP address, destination IP address and IP protocol type of network traffic against the firewall rules (in the order you list them). When the traffic matches a rule, the Device takes the action specified in the rule. Firewall rules are grouped based on the direction of travel of packets to which they apply:

LAN to Router LAN to WAN WAN to LAN WAN to Router Note: The LAN includes both the LAN port and the WLAN. By default, the Devices stateful packet inspection allows packets traveling in the following directions:

LAN to Router These rules specify which computers on the LAN can manage the Device (remote management). Note: You can also configure the remote management settings to allow only a specific computer to manage the Device. LAN to WAN These rules specify which computers on the LAN can access which computers or services on the WAN. By default, the Devices stateful packet inspection drops packets traveling in the following directions:

WAN to LAN These rules specify which computers on the WAN can access which computers or services on the LAN. Note: You also need to configure NAT port forwarding (or full featured NAT address mapping rules) to allow computers on the WAN to access devices on the LAN. VMG1312-T10C Users Guide 165 Chapter 14 Firewall WAN to Router By default the Device stops computers on the WAN from managing the Device. You could configure one of these rules to allow a WAN computer to manage the Device. Note: You also need to configure the remote management settings to allow a WAN computer to manage the Device. You may define additional rules and sets or modify existing ones but please exercise extreme caution in doing so. For example, you may create rules to:

Block certain types of traffic, such as IRC (Internet Relay Chat), from the LAN to the Internet. Allow certain types of traffic, such as Lotus Notes database synchronization, from specific hosts on the Internet to specific hosts on the LAN. Allow everyone except your competitors to access a web server. Restrict use of certain protocols, such as Telnet, to authorized users on the LAN. These custom rules work by comparing the source IP address, destination IP address and IP protocol type of network traffic to rules set by the administrator. Your customized rules take precedence and override the Devices default rules. 14.6.2 Guidelines For Enhancing Security With Your Firewall 1 2 3 Change the default password via web configurator. Think about access control before you connect to the network in any way. Limit who can access your router. 4 Don't enable any local service (such as telnet or FTP) 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. 5 6 7 For 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. Protect against IP spoofing by making sure the firewall is active. Keep the firewall in a secured (locked) room. 14.6.3 Security Considerations Note: Incorrectly configuring the firewall may block valid access or introduce security risks to the Device and your protected network. Use caution when creating or deleting firewall rules and test your rules after you configure them. Consider these security ramifications before creating a rule:

166 VMG1312-T10C Users Guide Chapter 14 Firewall 1 Does this rule stop LAN users from accessing critical resources on the Internet? For example, if IRC is blocked, are there users that require this service?

2 Is it possible to modify the rule to be more specific? For example, if IRC is blocked for all users, will a rule that blocks just certain users be more effective?

3 Does a rule that allows Internet users access to resources on the LAN create a security vulnerability? For example, if FTP ports (TCP 20, 21) are allowed from the Internet to the LAN, Internet users may be able to connect to computers with running FTP servers. 4 Does this rule conflict with any existing rules?

Once these questions have been answered, adding rules is simply a matter of entering the information into the correct fields in the web configurator screens. 14.6.4 Triangle Route When the firewall is on, your Device 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 Device to protect your LAN against attacks. Figure 113 Ideal Firewall Setup LAN 1 2 WAN 14.6.4.1 The Triangle Route Problem A traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet (through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the Devices LAN IP address), the triangle route (also called asymmetrical route) problem may occur. The steps below describe the triangle route problem. 1 2 3 A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN. The Device reroutes the SYN packet through Gateway A on the LAN to the WAN. The reply from the WAN goes directly to the computer on the LAN without going through the Device. As a result, the Device resets the connection, as the connection has not been acknowledged. VMG1312-T10C Users Guide 167 Chapter 14 Firewall Figure 114 Triangle Route Problem LAN 1 3 2 WAN ISP 1 ISP 2 14.6.4.2 Solving the Triangle Route Problem A If you have the Device allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the Device and its firewall protection. Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your Device supports up to three logical LAN interfaces with the Device being the gateway for each logical network. Its like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the Device to your LAN. The following steps describe such a scenario. A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. The Device reroutes the packet to Gateway A, which is in Subnet 2. The reply from the WAN goes to the Device. The Device then sends it to the computer on the LAN in Subnet 1.

VMG1312-T10C Users Guide 171 Chapter 15 Parental Control 172 VMG1312-T10C Users Guide CHAPTER 16 Certificates 16.1 Overview The Device can use certificates (also called digital IDs) to authenticate users. Certificates are based on public-private key pairs. A certificate contains the certificate owners identity and public key. Certificates provide a way to exchange public keys for use in authentication. 16.1.1 What You Can Do in this Chapter Use the Local Certificates screen to view and import the Devices CA-signed certificates

(Section 16.2 on page 175). Use the Trusted CA screen to save the certificates of trusted CAs to the Device. You can also export the certificates to a computer (Section 16.3 on page 177). 16.1.2 What You Need to Know The following terms and concepts may help as you read this chapter. Certification Authorities A 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. Public and Private Keys When 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. Public-key encryption in general works as follows. Tim wants to send a private message to Jenny. Tim generates a public-private key pair. What is encrypted with one key can only be decrypted using the other. Tim keeps the private key and makes the public key openly available. Tim uses his private key to encrypt the message and sends it to Jenny. Jenny receives the message and uses Tims public key to decrypt it. Additionally, Jenny uses her own private key to encrypt a message and Tim uses Jennys public key to decrypt the message. 1 2 3 4 5 VMG1312-T10C Users Guide 173 Chapter 16 Certificates The Device uses certificates based on public-key cryptology to authenticate users attempting to establish 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 authoritys public key to verify the certificates. Certification Path A certification path is the hierarchy of certification authority certificates that validate a certificate. The Device does not trust a certificate if any certificate on its path has expired or been revoked. Certificate Directory Servers Certification 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 Device can check a peers certificate against a directory servers list of revoked certificates. The framework of servers, software, procedures and policies that handles keys is called PKI (public-key infrastructure). Advantages of Certificates Certificates offer the following benefits. The Device 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. Certificate File Format The certification authority certificate that you want to import has to be in PEM (Base-64) encoded X.509 file format. This Privacy Enhanced Mail format uses 64 ASCII characters to convert a binary X.509 certificate into a printable form. 16.1.3 Verifying a Certificate Before you import a trusted CA or trusted remote host certificate into the Device, you should verify that you have the actual certificate. This is especially true of trusted CA certificates since the Device also trusts any valid certificate signed by any of the imported trusted CA certificates. You can use a certificates fingerprint to verify it. A certificates fingerprint is a message digest calculated using the MD5 or SHA1 algorithms. The following procedure describes how to check a certificates fingerprint to verify that you have the actual certificate. 1 Browse to where you have the certificate saved on your computer. 174 VMG1312-T10C Users Guide 2 Make sure that the certificate has a .cer or .crt file name extension. Figure 118 Certificates on Your Computer Chapter 16 Certificates 3 Double-click the certificates icon to open the Certificate window. Click the Details tab and scroll down to the Thumbprint Algorithm and Thumbprint fields. Figure 119 Certificate Details 4 Use a secure method to verify that the certificate owner has the same information in the Thumbprint Algorithm and Thumbprint fields. The secure method may very based on your situation. Possible examples would be over the telephone or through an HTTPS connection. 16.2 Local Certificates Use this screen to view the Devices summary list of certificates and certification requests.

Alerts and Logs An alert is a type of log that warrants more serious attention. They include system errors, attacks

(access control) and attempted access to blocked web sites. Some categories such as System Errors consist of both logs and alerts. You may differentiate them by their color in the View Log screen. Alerts display in red and logs display in black. Syslog Overview The syslog protocol allows devices to send event notification messages across an IP network to syslog servers that collect the event messages. A syslog-enabled device can generate a syslog message and send it to a syslog server. Syslog is defined in RFC 3164. The RFC defines the packet format, content and system log related information of syslog messages. Each syslog message has a facility and severity level. The syslog facility identifies a file in the syslog server. Refer to the documentation of your syslog program for details. The following table describes the syslog severity levels. Table 74 Syslog Severity Levels CODE 0 SEVERITY Emergency: The system is unusable. 1 2 Alert: Action must be taken immediately. Critical: The system condition is critical. VMG1312-T10C Users Guide 181 Chapter 17 System Monitor Table 74 Syslog Severity Levels (continued) CODE 3 SEVERITY Error: There is an error condition on the system. 4 5 6 7 Warning: There is a warning condition on the system.

The Device supports SNMP version VMG1312-T10C Users Guide 209 Chapter 25 Remote Management one (SNMPv1) and version two (SNMPv2c). The next figure illustrates an SNMP management operation. Figure 145 SNMP Management Model An SNMP managed network consists of two main types of component: agents and a manager. An agent is a management software module that resides in a managed device (the Device). 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. 210 VMG1312-T10C Users Guide Chapter 25 Remote Management 25.5.1 Configuring SNMP To change your Devices SNMP settings, click Maintenance > Remote MGMT > SNMP tab.

Table 94 Maintenance > Diagnostic > DSL Line: ADSL LABEL ATM Status DESCRIPTION Click this to view your DSL connections Asynchronous Transfer Mode (ATM) statistics. ATM is a networking technology that provides high-speed data transfer. ATM uses fixed-

size packets of information called cells. With ATM, a high QoS (Quality of Service) can be guaranteed. The (Segmentation and Reassembly) SAR driver translates packets into ATM cells. It also receives ATM cells and reassembles them into packets. These counters are set back to zero whenever the device starts up. inPkts is the number of good ATM cells that have been received. inDiscards is the number of received ATM cells that were rejected. outPkts is the number of ATM cells that have been sent. outDiscards is the number of ATM cells sent that were rejected. inF4Pkts is the number of ATM Operations, Administration, and Management (OAM) F4 cells that have been received. See ITU recommendation I.610 for more on OAM for ATM. outF4Pkts is the number of ATM OAM F4 cells that have been sent. inF5Pkts is the number of ATM OAM F5 cells that have been received. outF5Pkts is the number of ATM OAM F5 cells that have been sent. openChan is the number of times that the Device has opened a logical DSL channel. closeChan is the number of times that the Device has closed a logical DSL channel. txRate is the number of bytes transmitted per second. rxRate is the number of bytes received per second. ATM Loopback Test Click this to start the ATM loopback test. Make sure you have configured at least one PVC with proper VPIs/VCIs before you begin this test. The Device sends an OAM F5 packet to the DSLAM/ATM switch and then returns it (loops it back) to the Device. The ATM loopback test is useful for troubleshooting problems with the DSLAM and ATM network. VMG1312-T10C Users Guide 219 Chapter 26 Diagnostic Table 94 Maintenance > Diagnostic > DSL Line: ADSL (continued) LABEL DSL Line Status DESCRIPTION Click this to view statistics about the DSL connections. noise margin downstream is the signal to noise ratio for the downstream part of the connection (coming into the Device from the ISP). It is measured in decibels. The higher the number the more signal and less noise there is. output power upstream is the amount of power (in decibels) that the Device is using to transmit to the ISP. attenuation downstream is the reduction in amplitude (in decibels) of the DSL signal coming into the Device from the ISP. Discrete Multi-Tone (DMT) modulation divides up a lines bandwidth into sub-carriers

(sub-channels) of 4.3125 KHz each called tones. The rest of the display is the lines bit allocation. This is displayed as the number (in hexadecimal format) of bits transmitted for each tone. This can be used to determine the quality of the connection, whether a given sub-carrier loop has sufficient margins to support certain ADSL transmission rates, and possibly to determine whether particular specific types of interference or line attenuation exist. Refer to the ITU-T G.992.1 recommendation for more information on DMT. The better (or shorter) the line, the higher the number of bits transmitted for a DMT tone. The maximum number of bits that can be transmitted per DMT tone is 15. There will be some tones without any bits as there has to be space between the upstream and downstream channels.

How can I solve this problem?

The following factors may cause interference:

Obstacles: walls, ceilings, furniture, and so on. Building Materials: metal doors, aluminum studs. Electrical devices: microwaves, monitors, electric motors, cordless phones, and other wireless devices. To optimize the speed and quality of your wireless connection, you can:

Move your wireless device closer to the AP if the signal strength is low. Reduce wireless interference that may be caused by other wireless networks or surrounding wireless electronics such as cordless phones. Place the AP where there are minimum obstacles (such as walls and ceilings) between the AP and the wireless client. Reduce the number of wireless clients connecting to the same AP simultaneously, or add additional APs if necessary. Try closing some programs that use the Internet, especially peer-to-peer applications. If the wireless client is sending or receiving a lot of information, it may have too many programs open that use the Internet. What wireless security modes does my Device support?

Wireless security is vital to your network. It protects communications between wireless stations, access points and the wired network. The available security modes in your ZyXEL device are as follows:

WPA2-PSK: (recommended) This uses a pre-shared key with the WPA2 standard. WPA-PSK: This has the device use either WPA-PSK or WPA2-PSK depending on which security mode the wireless client uses. WPA2: WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. It requires the use of a RADIUS server and is mostly used in business networks. WPA: Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. It requires the use of a RADIUS server and is mostly used in business networks. WEP: Wired Equivalent Privacy (WEP) encryption scrambles the data transmitted between the wireless stations and the access points to keep network communications private.
