P-660H/HW/W-T Series User’ GuideIntroduction to DSL 40Introduction to DSLDSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted-pair wire that runs between the local telephone company switching offices and most homes and offices. While the wire itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000 Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to improve access to the Web - hence DSL technologies. There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for Internet users because more information is usually downloaded than uploaded. For example, a simple button click in a web browser can start an extended download that includes graphics and text.As data rates increase, the carrying distance decreases. That means that users who are beyond a certain distance from the telephone company’s central office may not be able to obtain the higher speeds.A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no dialing required. Introduction to ADSLIt is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream data rate. As mentioned, this works well for a typical Internet session in which more information is downloaded, for example, from Web servers, than is uploaded. ADSL operates in a frequency range that is above the frequency range of voice services, so the two systems can operate over the same cable.
P-660H/HW/W-T Series User’ Guide41 Introduction to DSL
P-660H/HW/W-T Series User’ GuideChapter 1 Getting To Know Your Prestige 42CHAPTER 1Getting To Know Your PrestigeThis chapter describes the key features and applications of your Prestige.1.1  Introducing the Prestige The Prestige is an ADSL2+ gateway that allows super-fast, secure Internet access over analog (POTS) or digital (ISDN) telephone lines (depending on your model). In the Prestige product name, “H” denotes an integrated 4-port switch (hub) and “W” denotes an included wireless LAN card that provides wireless connectivity. Models ending in “1”, for example P-660W-T1, denote a device that works over the analog telephone system, POTS (Plain Old Telephone Service). Models ending in “3” denote a device that works over ISDN (Integrated Services Digital Network). Models ending in “7” denote a device that works over T-ISDN (UR-2).Note: Only use firmware for your Prestige’s specific model. Refer to the label on the bottom of your Prestige.The DSL RJ-11 (ADSL over POTS models) or RJ-45 (ADSL over ISDN models) connects to your ADSL-enabled telephone line. The Prestige is compatible with the ADSL/ADSL2/ADSL2+ standards. Maximum data rates attainable by the Prestige for each standard are shown in the next table.Note: The standard your ISP supports determines the maximum upstream and downstream speeds attainable. Actual speeds attained also depend on the distance from your ISP, line quality, etc.1.2  FeaturesThe following sections describe the features of the Prestige. Table 1   ADSL StandardsDATA RATE STANDARD         UPSTREAM DOWNSTREAMADSL 832 kbps 8MbpsADSL2 3.5Mbps 12MbpsADSL2+ 3.5Mbps 24Mbps
P-660H/HW/W-T Series User’ Guide43 Chapter 1 Getting To Know Your PrestigeNote: See the product specifications in the appendix for detailed features and standards support. High Speed Internet AccessYour Prestige ADSL/ADSL2/ADSL2+ router can support downstream transmission rates of up to 24Mbps and upstream transmission rates of 3.5Mbps. Actual speeds attained depend on the ADSL service you subscribed to, distance from your ISP, line quality, etc. Zero Configuration Internet AccessOnce you connect and turn on the Prestige, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the Prestige cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.Any IPThe Any IP feature allows a computer to access the Internet and the Prestige without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the Prestige are not in the same subnet.FirewallThe Prestige is a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The Prestige firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.Content FilteringContent filtering allows you to block access to forbidden Internet web sites, schedule when the Prestige should perform the filtering and give trusted LAN IP addresses unfiltered Internet access.Traffic RedirectTraffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the Internet, thus acting as an auxiliary if your regular WAN connection fails.Media Bandwidth ManagementZyXEL’s Media Bandwidth Management allows you to specify bandwidth classes based on an application and/or subnet. You can allocate specific amounts of bandwidth capacity (bandwidth budgets) to different bandwidth classes.
P-660H/HW/W-T Series User’ GuideChapter 1 Getting To Know Your Prestige 44Universal Plug and Play (UPnP)Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically join a network, obtain an IP address and convey its capabilities to other devices on the network.PPPoE (RFC2516)PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the Prestige is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual computers. The Prestige also includes PPPoE idle time-out (the PPPoE connection terminates after a period of no traffic that you configure) and PPPoE Dial-on-Demand (the PPPoE connection is brought up only when an Internet access request is made).Network Address Translation (NAT)Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).Dynamic DNS SupportWith Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider.DHCPDHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. The Prestige can now also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.IP AliasIP Alias allows you to partition a physical network into logical networks over the same Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the Prestige itself as the gateway for each LAN network.IP Policy Routing (IPPR)Traditionally, routing is based on the destination address only and the router takes the shortest path to forward a packet.  IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator.
P-660H/HW/W-T Series User’ Guide45 Chapter 1 Getting To Know Your PrestigePacket FiltersThe Prestige's packet filtering functions allows added network security and management.HousingYour Prestige's compact and ventilated housing minimizes space requirements making it easy to position anywhere in your busy office. 4-Port Switch (P-660H/P-660HW)A combination of switch and router makes your Prestige a cost-effective and viable network solution. You can connect up to four computers to the Prestige without the cost of a hub. Use a hub to add more than four computers to your LAN.1.2.1  Wireless Features (P-660HW/P-660W)Wireless LANThe Prestige supports the IEEE 802.11g standard, which is fully compatible with the IEEE 802.11b standard, meaning that you can have both IEEE 802.11b and IEEE 802.11g wireless clients in the same wireless network.Note: The Prestige may be prone to RF (Radio Frequency) interference from other 2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth enabled devices, and other wireless LANs.Wi-Fi Protected AccessWi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification standard. Key differences between WPA and WEP are user authentication and improved data encryption.AntennaThe Prestige is equipped with one 2dBi fixed antenna to provide clear radio signal between the wireless stations and the access points. Wireless LAN MAC Address FilteringYour Prestige can check the MAC addresses of wireless stations against a list of allowed or denied MAC addresses.WEP EncryptionWEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network to help keep network communications private.
P-660H/HW/W-T Series User’ GuideChapter 1 Getting To Know Your Prestige 461.3  Applications for the PrestigeHere are some example uses for which the Prestige is well suited. Application graphics shown are for the P-660W. 1.3.1  Protected Internet AccessThe Prestige is the ideal high-speed Internet access solution. It is compatible with all major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers and supports the ADSL standards as shown in Table 1 on page 42. In addition, the Prestige allows wireless clients access to your network resources. The Prestige provides protection from attacks by Internet hackers. By default, the firewall blocks all incoming traffic from the WAN. The firewall supports TCP/UDP inspection and DoS (Denial of Services) detection and prevention, as well as real time alerts, reports and logs.Figure 1   Protected Internet Access Applicationsss1.3.2  LAN to LAN ApplicationYou can use the Prestige to connect two geographically dispersed networks over the ADSL line.

P-660H/HW/W-T Series User’ GuideChapter 4 LAN Setup 62CHAPTER 4LAN SetupThis chapter describes how to configure LAN settings.4.1  LAN Overview A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses.  See Section 4.3 on page 68 to configure the LAN screens. 4.1.1 LANs, WANs and the PrestigeThe actual physical connection determines whether the Prestige 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 15   LAN and WAN IP Addresses
P-660H/HW/W-T Series User’ Guide63 Chapter 4 LAN Setup4.1.2  DHCP SetupDHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to obtain TCP/IP configuration at start-up from a server. You can configure the Prestige as a DHCP server or disable it. When configured as a server, the Prestige 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. 4.1.2.1  IP Pool SetupThe Prestige 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.4.1.3  DNS Server AddressDNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a machine before you can access it.  The DNS server addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP address and subnet mask.There are two ways that an ISP disseminates the DNS server addresses.  The first is for an ISP to tell a customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up.  If your ISP gives you the DNS server addresses, enter them in the DNS Serverfields in DHCP Setup, otherwise, leave them blank.Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up.  If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation.  The Prestige supports the IPCP DNS server extensions through the DNS proxy feature.If the Primary and Secondary DNS Server fields in the LAN Setup screen are not specified,for instance, left as 0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server.  When a computer sends a DNS query to the Prestige, the Prestige forwards the query to the real DNS server learned through IPCP and relays the response back to the computer.Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions.  It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances.  If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the LAN Setup screen.  This way, the Prestige can pass the DNS servers to the computers and the computers can query the DNS server directly without the Prestige’s intervention.4.1.4  DNS Server Address AssignmentUse DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it.
P-660H/HW/W-T Series User’ GuideChapter 4 LAN Setup 64There are two ways that an ISP disseminates the DNS server addresses. • The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the LAN Setup screen.• The Prestige acts as a DNS proxy when the Primary and Secondary DNS Server fieldsare left blank in the LAN Setup screen.4.2  LAN TCP/IP The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.4.2.1  IP Address and Subnet MaskSimilar to the way houses on a street share a common street name, so too do computers on a LAN share one common network number.Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. 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 Prestige. 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 Prestige, 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 Prestige 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 Prestige unless you are instructed to do otherwise.
P-660H/HW/W-T Series User’ Guide65 Chapter 4 LAN Setup4.2.1.1  Private IP AddressesEvery 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 — 192.168.255.255You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.Note:  Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. For more information on address assignment, please refer to RFC 1597, Address Allocation for Private Internets and RFC 1466, Guidelines for Management of IP Address Space.4.2.2  RIP SetupRIP (Routing Information Protocol) allows a router to exchange routing information with other routers.  The RIP Direction field controls the sending and receiving of RIP packets.  When set to:•Both - the Prestige will broadcast its routing table periodically and incorporate the RIP information that it receives.•In Only - the Prestige will not send any RIP packets but will accept all RIP packets received.•Out Only - the Prestige will send out RIP packets but will not accept any RIP packets received.•None - the Prestige will not send any RIP packets and will ignore any RIP packets received.The Version field controls the format and the broadcasting method of the RIP packets that the Prestige sends (it recognizes both formats when receiving).  RIP-1 is universally supported; but RIP-2 carries more information.  RIP-1 is probably adequate for most networks, unless you have an unusual network topology.Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.
P-660H/HW/W-T Series User’ GuideChapter 4 LAN Setup 664.2.3  MulticastTraditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast computers. The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned to the multicast routers group. The Prestige supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the Prestige queries all directly connected networks to gather group membership. After that, the Prestige periodically updates this information. IP multicasting can be enabled/disabled on the Prestige LAN and/or WAN interfaces in the web configurator (LAN; WAN ).Select None to disable IP multicasting on these interfaces.4.2.4  Any IPTraditionally, you must set the IP addresses and the subnet masks of a computer and the Prestige to be in the same subnet to allow the computer to access the Internet (through the Prestige). In cases where your computer is required to use a static IP address in another network, you may need to manually configure the network settings of the computer every time you want to access the Internet via the Prestige. With the Any IP feature and NAT enabled, the Prestige allows a computer to access the Internet without changing the network settings (such as IP address and subnet mask) of the computer, when the IP addresses of the computer and the Prestige are not in the same subnet.  Whether a computer is set to use a dynamic or static (fixed) IP address, you can simply connect the computer to the Prestige and access the Internet. The following figure depicts a scenario where a computer is set to use a static private IP address in the corporate environment. In a residential house where a Prestige is installed, you can still use the computer to access the Internet without changing the network settings, even when the IP addresses of the computer and the Prestige are not in the same subnet.
P-660H/HW/W-T Series User’ Guide67 Chapter 4 LAN SetupFigure 16   Any IP ExampleThe Any IP feature does not apply to a computer using either a dynamic IP address or a static IP address that is in the same subnet as the Prestige’s IP address.Note: You must enable NAT/SUA to use the Any IP feature on the Prestige. 4.2.4.1  How Any IP WorksAddress Resolution Protocol (ARP) is a protocol for mapping an Internet Protocol address (IP address) to a physical machine address, also known as a Media Access Control or MAC address, on the local area network. IP routing table is defined on IP Ethernet devices (the Prestige) to decide which hop to use, to help forward data along to its specified destination.The following lists out the steps taken, when a computer tries to access the Internet for the first time through the Prestige.1When a computer (which is in a different subnet) first attempts to access the Internet, it sends packets to its default gateway (which is not the Prestige) by looking at the MAC address in its ARP table. 2When the computer cannot locate the default gateway, an ARP request is broadcast on the LAN.3The Prestige receives the ARP request and replies to the computer with its own MAC address. 4The computer updates the MAC address for the default gateway to the ARP table. Once the ARP table is updated, the computer is able to access the Internet through the Prestige. 5When the Prestige receives packets from the computer, it creates an entry in the IP routing table so it can properly forward packets intended for the computer. After all the routing information is updated, the computer can access the Prestige and the Internet as if it is in the same subnet as the Prestige.

P-660H/HW/W-T Series User’ GuideChapter 5 Wireless LAN 70CHAPTER 5Wireless LANThis chapter discusses how to configure the Wireless LAN screens for P-660HW or P-660W.5.1  Wireless LAN Introduction A wireless LAN can be as simple as two computers with wireless LAN adapters communicating in a peer-to-peer network or as complex as a number of computers with wireless LAN adapters communicating through access points which bridge network traffic to the wired LAN. Refer to Section 5.3 on page 71 to configure wireless LAN settings. Note: See the WLAN appendix for more detailed information on WLANs.5.2  Wireless Security Overview Wireless security is vital to your network to protect wireless communication between wireless stations, access points and the wired network.Wireless security methods available on the Prestige are data encryption, wireless client authentication, restricting access by device MAC address and hiding the Prestige identity.5.2.1  Encryption• Use WPA security if you have WPA-aware wireless clients and a RADIUS server. WPA has user authentication and improved data encryption over WEP.• Use WPA-PSK if you have WPA-aware wireless clients but no RADIUS server.• If you don’t have WPA-aware wireless clients, then use WEP key encrypting. A higher bit key offers better security at a throughput trade-off. You can use Passphrase to automatically generate 64-bit or 128-bit WEP keys or manually enter 64-bit, 128-bit or 256-bit WEP keys.5.2.2  AuthenticationWPA has user authentication and you can also configure IEEE 802.1x to use the built-in database (Local User Database) or a RADIUS server to authenticate wireless clients before joining your network.
P-660H/HW/W-T Series User’ Guide71 Chapter 5 Wireless LAN• Use RADIUS authentication if you have a RADIUS server. See the appendices for information on protocols used when a client authenticates with a RADIUS server via the Prestige.• Use the Local User Database if you have less than 32 wireless clients in your network. The Prestige uses MD5 encryption when a client authenticates with the Local User Database 5.2.3  Restricted AccessThe MAC Filter screen allows you to configure the AP to give exclusive access to devices (Allow Association) or exclude them from accessing the AP (Deny Association).5.2.4  Hide Prestige IdentityIf you hide the ESSID, then the Prestige cannot be seen when a wireless client scans for local APs. The trade-off for the extra security of “hiding” the Prestige may be inconvenience for some valid WLAN clients. If you don’t hide the ESSID, at least you should change the default one.5.3  The Main Wireless LAN Screen  Click Wireless LAN in the navigation panel to display the main Wireless LAN screen.

P-660H/HW/W-T Series User’ Guide73 Chapter 5 Wireless LANFigure 19   Wireless Security MethodsNote: You must enable the same wireless security settings on the Prestige and on all wireless clients that you want to associate with it. If you do not enable any wireless security on your Prestige, your network is accessible to any wireless networking device that is within range. 5.4  Configuring the Wireless Screen 5.4.1  WEP EncryptionWEP encryption scrambles the data transmitted between the wireless stations and the access points to keep network communications private. It encrypts unicast and multicast communications in a network. Both the wireless stations and the access points must use the same WEP key. Your Prestige allows you to configure up to four 64-bit, 128-bit or 256-bit WEP keys but only one key can be enabled at any one time. In order to configure and enable WEP encryption; click Wireless LAN and Wireless to the display the Wireless screen.
P-660H/HW/W-T Series User’ GuideChapter 5 Wireless LAN 74Figure 20   Wireless ScreenThe following table describes the labels in this screen.Table 13   Wireless LANLABEL DESCRIPTIONEnable Wireless LANYou should configure some wireless security (see Figure 19 on page 73) when you enable the wireless LAN. Select the check box to enable the wireless LAN.ESSID The ESSID (Extended Service Set IDentification) is a unique name to identify the Prestige in the wireless LAN. Wireless stations associating to the Prestige must have the same ESSID. Enter a descriptive name of up to 32 printable characters (including spaces; alphabetic characters are case-sensitive).Hide ESSID Select Yes to hide the ESSID in so a station cannot obtain the ESSID through AP scanning.Select No to make the ESSID visible so a station can obtain the ESSID through AP scanning.Channel ID  The radio frequency used by IEEE 802.11a, b or g wireless devices is called a channel. Select a channel from the drop-down list box.RTS/CTS ThresholdThe RTS (Request To Send) threshold (number of bytes) is for enabling RTS/CTS. Data with its frame size larger than this value will perform the RTS/CTS handshake. Setting this value to be larger than the maximum MSDU (MAC service data unit) size turns off RTS/CTS. Setting this value to zero turns on RTS/CTS. Select the check box to change the default value and enter a new value between 0 and 2432.
P-660H/HW/W-T Series User’ Guide75 Chapter 5 Wireless LANNote: If you are configuring the Prestige from a computer connected to the wireless LAN and you change the Prestige’s ESSID or security settings (see Figure 19 on page 73), 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 Prestige’s new settings.5.5  Configuring MAC FiltersEvery Ethernet device has a unique MAC (Media Access Control) address. The MAC address is assigned at the factory and consists of six pairs of hexadecimal characters, for example, 00:A0:C5:00:00:02. You need to know the MAC addresses of the devices to configure this screen. To change your Prestige’s MAC filter settings, click Wireless LAN,MAC Filter to open the MAC Filter screen. The screen appears as shown.Fragmentation Threshold This is the threshold (number of bytes) for the fragmentation boundary for directed messages. It is the maximum data fragment size that can be sent. Select the check box to change the default value and enter a value between 256 and 2432.You won’t see the following WEP-related fields if you have WPA or WPA-PSK enabled.Passphrase Enter a "passphrase" (password phrase) of up to 63 case-sensitive printable characters and click Generate to have the Prestige create four different WEP keys. At the time of writing, you cannot use passphrase to generate 256-bit WEP keys. Generate After you enter the passphrase, click Generate to have the Prestige generate four different WEP keys automatically. The keys display in the fields below. WEP Encryption WEP (Wired Equivalent Privacy) encrypts data frames before transmitting over the wireless network. Select Disable to allow all wireless stations to communicate with the access points without any data encryption. Select 64-bit WEP,128-bit WEP or 256-bit WEP to use data encryption. Key 1 to Key 4  The WEP keys are used to encrypt data. Both the Prestige and the wireless stations must use the same WEP key for data transmission.If you want to manually set the WEP keys, enter the key in the field provided.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"). If you chose 256-bit WEP, then enter 29 ASCII characters or 58 hexadecimal characters ("0-9", "A-F").The values for the WEP keys must be set up exactly the same on all wireless devices in the same wireless LAN.You must configure all four keys, but only one key can be used at any one time. The default key is key 1.Back Click Back to go to the main wireless LAN setup screen. Apply Click Apply to save your changes back to the Prestige.

P-660H/HW/W-T Series User’ Guide77 Chapter 5 Wireless LAN5.6  Introduction to WPA  Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA is preferred to WEP as WPA has user authentication and improved data encryption. See the appendix for more information on WPA user authentication and WPA encryption.If you don’t have an external RADIUS server, you should use WPA-PSK (WPA -Pre-Shared Key). WPA-PSK only requires a single (identical) password entered into each WLAN member. As long as the passwords match, a client will be granted access to a WLAN. Note: You can’t use the Local User Database for authentication when you select WPA.5.6.1  WPA-PSK Application ExampleA WPA-PSK application looks as follows.1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must be between 8 and 63 printable characters (including spaces; alphabetic characters are case-sensitive).2The AP checks each client’s password and (only) allows it to join the network if the passwords match.3The AP derives and distributes keys to the wireless clients.4The AP and wireless clients use the TKIP encryption process to encrypt data exchanged between them.MAC Address  Enter the MAC addresses in a valid MAC address format, that is, six hexadecimal character pairs, for example, 12:34:56:78:9a:bc of the wireless stations that are allowed or denied access to the Prestige in these address fields.Back Click Back to go to the main wireless LAN setup screen.Apply Click Apply to save your changes back to the Prestige.

A WPA application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system (wired link to the LAN).1The AP passes the wireless client’s authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly transmitted between the AP and the wireless clients

P-660H/HW/W-T Series User’ GuideChapter 6 WAN Setup 90CHAPTER 6WAN SetupThis chapter describes how to configure WAN settings.6.1  WAN Overview A WAN (Wide Area Network) is an outside connection to another network or the Internet.6.1.1  EncapsulationBe sure to use the encapsulation method required by your ISP. The Prestige supports the following methods.6.1.1.1  ENET ENCAPThe MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the ENET ENCAP Gateway field in the second wizard screen. You can get this information from your ISP.6.1.1.2  PPP over EthernetPPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP. The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC (Permanent Virtual Circuit) which connects to ADSL Access Concentrator where the PPP session terminates. One PVC can support any number of PPP sessions from your LAN. For more information on PPPoE, see the appendices.6.1.1.3  PPPoAPPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). A PPPoA connection functions like a dial-up Internet connection. The Prestige encapsulates the PPP session based on RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Provider’s (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.
P-660H/HW/W-T Series User’ Guide91 Chapter 6 WAN Setup6.1.1.4  RFC 1483RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.6.1.2  MultiplexingThere are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.6.1.2.1  VC-based MultiplexingIn this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.6.1.2.2  LLC-based MultiplexingIn 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.6.1.3  VPI and VCIBe 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.6.1.4  IP Address AssignmentA 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.6.1.4.1  IP Assignment with PPPoA or PPPoE EncapsulationIf you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the ENET ENCAP Gateway field.
P-660H/HW/W-T Series User’ GuideChapter 6 WAN Setup 926.1.4.2  IP Assignment with RFC 1483 EncapsulationIn this case the IP Address Assignment must be static with the same requirements for the IP Address and ENET ENCAP Gateway fields as stated above.6.1.4.3  IP Assignment with ENET ENCAP EncapsulationIn this case you can have either a static or dynamic IP. For a static IP you must fill in all the IPAddress and ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the Prestige acts as a DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable (N/A) as the DHCP server assigns them to the Prestige.6.1.5  Nailed-Up Connection (PPP)A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the Prestige will try to bring up the connection when turned on and whenever the connection is down. A nailed-up connection can be very expensive for obvious reasons. Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a constant connection and the cost is of no concern6.1.6  NATNAT (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.6.2  Metric The metric represents the "cost of transmission". A router determines the best route for transmission by choosing a path with the lowest "cost". RIP routing uses hop count as the measurement of cost, with a minimum of "1" for directly connected networks. The number must be between "1" and "15"; a number greater than "15" means the link is down. The smaller the number, the lower the "cost".The metric sets the priority for the Prestige’s routes to the Internet. If any two of the default routes have the same metric, the Prestige uses the following pre-defined priorities:• Normal route: designated by the ISP (see Section 6.7 on page 95)• Traffic-redirect route (see Section 6.8 on page 98)• WAN-backup route, also called dial-backup (see Section 6.9 on page 99)
P-660H/HW/W-T Series User’ Guide93 Chapter 6 WAN SetupFor example, if the normal route has a metric of "1" and the traffic-redirect route has a metric of "2" and dial-backup route has a metric of "3", then the normal route acts as the primary default route. If the normal route fails to connect to the Internet, the Prestige tries the traffic-redirect route next. In the same manner, the Prestige uses the dial-backup route if the traffic-redirect route also fails. If you want the dial-backup route to take first priority over the traffic-redirect route or even the normal route, all you need to do is set the dial-backup route’s metric to "1" and the others to "2" (or greater).IP Policy Routing overrides the default routing behavior and takes priority over all of the routes mentioned above.6.3  PPPoE EncapsulationThe Prestige supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for 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 provides a login and authentication method that the existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or procedures for Windows users.One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals.Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site.By implementing PPPoE directly on the Prestige (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the Prestige does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.6.4  Traffic ShapingTraffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and fluctuations of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections.
P-660H/HW/W-T Series User’ GuideChapter 6 WAN Setup 94Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed.Sustained Cell Rate (SCR) is the mean cell rate of each bursty traffic source. It specifies the maximum average rate at which cells can be sent over the virtual connection. SCR may not be greater than the PCR.Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again.If the PCR, SCR or MBS is set to the default of "0", the system will assign a maximum value that correlates to your upstream line rate. The following figure illustrates the relationship between PCR, SCR and MBS. Figure 31   Example of Traffic Shaping6.5  Zero Configuration Internet AccessOnce you turn on and connect the Prestige to a telephone jack, it automatically detects the Internet connection settings (such as the VCI/VPI numbers and the encapsulation method) from the ISP and makes the necessary configuration changes. In cases where additional account information (such as an Internet account user name and password) is required or the Prestige cannot connect to the ISP, you will be redirected to web screen(s) for information input or troubleshooting.Zero configuration for Internet access is disable when • the Prestige is in bridge mode• you set the Prestige to use a static (fixed) WAN IP address.

P-660H/HW/W-T Series User’ GuideChapter 7 Network Address Translation (NAT) Screens 102CHAPTER 7Network Address Translation(NAT) ScreensThis chapter discusses how to configure NAT on the Prestige.7.1  NAT 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. 7.1.1  NAT DefinitionsInside/outside denotes where a host is located relative to the Prestige, 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. 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.NAT never changes the IP address (either local or global) of an outside host.Table 24   NAT DefinitionsITEM DESCRIPTIONInside This refers to the host on the LAN.Outside This refers to the host on the WAN.Local This refers to the packet address (source or destination) as the packet travels on the LAN.Global This refers to the packet address (source or destination) as the packet travels on the WAN.
P-660H/HW/W-T Series User’ Guide103 Chapter 7 Network Address Translation (NAT) Screens7.1.2  What NAT DoesIn the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side.  When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed.The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world. If you do not define any servers (for Many-to-One and Many-to-Many Overload mapping – see Table 25 on page 105),NAT offers the additional benefit of firewall protection. With no servers defined, your Prestige 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).7.1.3  How NAT WorksEach packet has two addresses – a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address (and TCP or UDP source port numbers for Many-to-One and Many-to-Many Overload NAT mapping) in each packet and then forwards it to the Internet. The Prestige keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.

They are:•One to One: In One-to-One mode, the Prestige maps one local IP address to one global IP address.•Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s Single User Account feature that previous ZyXEL routers supported (the SUA Only option in today’s routers). •Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP addresses to shared global IP addresses.•Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP address to a unique global IP address. •Server: This type allows you to specify inside servers of different services behind the NAT to be accessible to the outside world.Port numbers do NOT change for One-to-One and Many-to-Many No Overload NAT mapping types. The following table summarizes these types.Table 25   NAT Mapping TypesTYPE IP MAPPING SMT ABBREVIATIONOne-to-One ILA1ÅÆ IGA1 1:1Many-to-One (SUA/PAT) ILA1ÅÆ IGA1ILA2ÅÆ IGA1…M:1Many-to-Many Overload ILA1ÅÆ IGA1ILA2ÅÆ IGA2ILA3ÅÆ IGA1ILA4ÅÆ IGA2…M:M OvMany-to-Many No Overload ILA1ÅÆ IGA1ILA2ÅÆ IGA2ILA3ÅÆ IGA3…M:M No OVServer Server 1 IPÅÆ IGA1Server 2 IPÅÆ IGA1Server 3 IPÅÆ IGA1Server

The Prestige also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers using mapping types as outlined in Table 25 on page 105.• Choose SUA Only if you have just one public WAN IP address for your Prestige.• Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.7.3  SUA Server A SUA server 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 SUA makes your whole inside network appear as a single computer to the outside world. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. You can allocate a server IP address that corresponds to a port or a range of ports.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.7.3.1  Default Server IP AddressIn addition to the servers for specified services, NAT supports a default server IP address. A default server receives packets from ports that are not specified in this screen.If you do not assign an IP address in Server Set 1 (default server) the Prestige discards all packets received for ports that are not specified here or in the remote management setup.7.3.2  Port Forwarding: Services and Port NumbersThe most often used port numbers are shown in the following table.

P-660H/HW/W-T Series User’ GuideChapter 7 Network Address Translation (NAT) Screens 1107.6  Configuring Address Mapping Rules Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a rule matches the current packet, the Prestige takes the corresponding action and the remaining rules are ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up by that number of empty rules. For example, if you have already configured rules 1 to 6 in your current set and now you configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new rules 4, 5 and 6.

P-660H/HW/W-T Series User’ GuideChapter 8 Dynamic DNS Setup 114CHAPTER 8Dynamic DNS SetupThis chapter discusses how to configure your Prestige to use Dynamic DNS.8.1  Dynamic DNS OverviewDynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe, etc.). You can also access your FTP server or Web site on your own computer using a domain name (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address.First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key. 8.1.1  DYNDNS WildcardEnabling 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.See Section 8.2 on page 114 for configuration instruction. 8.2  Configuring Dynamic DNS To change your Prestige’s DDNS, click Dynamic DNS.

P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 118CHAPTER 10FirewallsThis chapter gives some background information on firewalls and introduces the Prestige firewall.10.1  Firewall Overview Originally, the term firewall referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term “firewall” is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from an untrusted network. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself. Refer to Section 11.5 on page 135 to configure default firewall settings. Refer to Section 11.6 on page 136 to view firewall rules. Refer to Section 11.6.1 on page 138 to configure firewall rules. Refer to Section 11.7 on page 141 to configure a custom service. Refer to Section 11.12.3 on page 151 to configure firewall thresholds. 10.2  Types of FirewallsThere are three main types of firewalls:• Packet Filtering Firewalls• Application-level Firewalls• Stateful Inspection Firewalls10.2.1  Packet Filtering FirewallsPacket filtering firewalls restrict access based on the source/destination computer network address of a packet and the type of application.
P-660H/HW/W-T Series User’ Guide119 Chapter 10 Firewalls10.2.2  Application-level FirewallsApplication-level firewalls restrict access by serving as proxies for external servers. Since they use programs written for specific Internet services, such as HTTP, FTP and telnet, they can evaluate network packets for valid application-specific data. Application-level gateways have a number of general advantages over the default mode of permitting application traffic directly to internal hosts:Information hiding prevents the names of internal systems from being made known via DNS to outside systems, since the application gateway is the only host whose name must be made known to outside systems.Robust authentication and logging pre-authenticates application traffic before it reaches internal hosts and causes it to be logged more effectively than if it were logged with standard host logging. Filtering rules at the packet filtering router can be less complex than they would be if the router needed to filter application traffic and direct it to a number of specific systems. The router need only allow application traffic destined for the application gateway and reject the rest.10.2.3   Stateful Inspection Firewalls Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency, however, they may lack the granular application level access control or caching that some proxies support. See Section 10.5 on page 124 for more information on stateful inspection.Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises.10.3  Introduction to ZyXEL’s FirewallThe Prestige firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (in SMT menu 21.2 or in the web configurator). The Prestige’s purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The Prestige can be used to prevent theft, destruction and modification of data, as well as log events, which may be important to the security of your network. The Prestige also has packet filtering capabilities.The Prestige is installed between the LAN and the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The Prestige has one DSL/ISDN port and one Ethernet LAN port, which physically separate the network into two areas.• The DSL/ISDN port connects to the Internet.
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 120• The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP, and the World Wide Web.  However, “inbound access” will not be allowed unless you configure remote management or create a firewall rule to allow a remote host to use a specific service.10.3.1  Denial of Service AttacksFigure 46   Prestige Firewall Application10.4  Denial of ServiceDenials 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 Prestige is pre-configured to automatically detect and thwart all known DoS attacks.10.4.1  BasicsComputers share information over the Internet using a common language called TCP/IP. TCP/IP, in turn, is a set of application protocols that perform specific functions. An “extension number”, called the "TCP port" or "UDP port" identifies these protocols, such as HTTP (Web), FTP (File Transfer Protocol), POP3 (E-mail), etc. For example, Web traffic by default uses TCP port 80. When computers communicate on the Internet, they are using the client/server model, where the server "listens" on a specific TCP/UDP port for information requests from remote client computers on the network. For example, a Web server typically listens on port 80. Please note that while a computer may be intended for use over a single port, such as Web on port 80, other ports are also active. If the person configuring or managing the computer is not careful, a hacker could attack it over an unprotected port. Some of the most common IP ports are:
P-660H/HW/W-T Series User’ Guide121 Chapter 10 Firewalls10.4.2  Types of DoS AttacksThere are four types of DoS attacks: 1Those that exploit bugs in a TCP/IP implementation.2Those that exploit weaknesses in the TCP/IP specification.3Brute-force attacks that flood a network with useless data. 4IP Spoofing.5"Ping of Death" and "Teardro p " attacks exploit bugs in the TCP/IP implementations of various computer and host systems. • Ping of Death uses a "ping" utility to create an IP packet that exceeds the maximum 65,536 bytes of data allowed by the IP specification. The oversize packet is then sent to an unsuspecting system. Systems may crash, hang or reboot. • Teardrop attack exploits weaknesses in the re-assembly of IP packet fragments. As data is transmitted through a network, IP packets are often broken up into smaller chunks. Each fragment looks like the original IP packet except that it contains an offset field that says, for instance, "This fragment is carrying bytes 200 through 400 of the original (non fragmented) IP packet." The Teardrop program creates a series of IP fragments with overlapping offset fields. When these fragments are reassembled at the destination, some systems will crash, hang, or reboot. 6Weaknesses in the TCP/IP specification leave it open to "SYN Flood" and "LAND"attacks. These attacks are executed during the handshake that initiates a communicationsession between two applications.Table 33   Common IP Ports21 FTP 53 DNS23 Telnet 80 HTTP25 SMTP 110 POP3
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 122Figure 47   Three-Way HandshakeUnder 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. •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 what is known as a backlog queue. SYN-ACKs are moved off the queue only when an ACK comes back or when an internal timer (which is set at relatively long intervals) 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. Figure 48   SYN Flood•In a LAND Attack, hackers flood SYN packets into the network with a spoofed source IP address of the targeted 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. 7Abrute-force attack, such as a "Smurf" attack, targets a feature in the IP specification known as directed or subnet broadcasting, to quickly flood the target network with useless data. A Smurf hacker floods a router with Internet Control Message Protocol
P-660H/HW/W-T Series User’ Guide123 Chapter 10 Firewalls(ICMP) echo request packets (pings). Since the destination IP address of each packet is the broadcast address of the network, the router will broadcast the ICMP echo request packet to all hosts on the network. If there are numerous hosts, this will create a large amount of ICMP echo request and response traffic. If a hacker chooses to spoof the source IP address of the ICMP echo request packet, the resulting ICMP traffic will not only clog up the "intermediary" network, but will also congest the network of the spoofed source IP address, known as the "victim" network. This flood of broadcast traffic consumes all available bandwidth, making communications impossible. Figure 49   Smurf Attack10.4.2.1  ICMP Vulnerability ICMP is an error-reporting protocol that works in concert with IP. The following ICMP types trigger an alert:10.4.2.2  Illegal Commands (NetBIOS and SMTP)The only legal NetBIOS commands are the following - all others are illegal.Table 34   ICMP Commands That Trigger Alerts5REDIRECT13 TIMESTAMP_REQUEST14 TIMESTAMP_REPLY17 ADDRESS_MASK_REQUEST18 ADDRESS_MASK_REPLYTable 35   Legal NetBIOS CommandsMESSAGE:REQUEST:POSITIVE:VE:
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 124All SMTP commands are illegal except for those displayed in the following tables. 10.4.2.3  TracerouteTraceroute is a utility used to determine the path a packet takes between two endpoints. Sometimes when a packet filter firewall is configured incorrectly an attacker can traceroute the firewall gaining knowledge of the network topology inside the firewall.Often, many DoS attacks also employ a technique known as "IP Spoofing" as part of their attack. IP Spoofing may be used to break into systems, to hide the hacker's identity, or to magnify the effect of the DoS attack. IP Spoofing is a technique used to gain unauthorized access to computers by tricking a router or firewall into thinking that the communications are coming from within the trusted network. To engage in IP spoofing, a hacker must modify the packet headers so that it appears that the packets originate from a trusted host and should be allowed through the router or firewall. The Prestige blocks all IP Spoofing attempts.10.5  Stateful InspectionWith stateful inspection, fields of the packets are compared to packets that are already known to be trusted. For example, if you access some outside service, the proxy server remembers things about your original request, like the port number and source and destination addresses. This “remembering” is called saving the state. When the outside system responds to your request, the firewall compares the received packets with the saved state to determine if they are allowed in. The Prestige uses stateful packet inspection to protect the private LAN from hackers and vandals on the Internet. By default, the Prestige’s stateful inspection allows all communications to the Internet that originate from the LAN, and blocks all traffic to the LAN that originates from the Internet. In summary, stateful inspection: • Allows all sessions originating from the LAN (local network) to the WAN (Internet).• Denies all sessions originating from the WAN to the LAN.RETARGET:KEEPALIVE:Table 36    Legal SMTP CommandsAUTH DATA EHLO ETRN EXPN HELO HELP MAIL NOOPQUIT RCPT RSET SAML SEND SOML TURN VRFYTable 35   Legal NetBIOS Commands
P-660H/HW/W-T Series User’ Guide125 Chapter 10 FirewallsFigure 50   Stateful InspectionThe previous figure shows the Prestige’s default firewall rules in action as well as demonstrates how stateful inspection works. User A can initiate a Telnet session from within the LAN and responses to this request are allowed. However other Telnet traffic initiated from the WAN is blocked.10.5.1  Stateful Inspection ProcessIn this example, the following sequence of events occurs when a TCP packet leaves the LAN network through the firewall's WAN interface. The TCP packet is the first in a session, and the packet's application layer protocol is configured for a firewall rule inspection:1The packet travels from the firewall's LAN to the WAN.2The packet is evaluated against the interface's existing outbound access list, and the packet is permitted (a denied packet would simply be dropped at this point).3The packet is inspected by a firewall rule to determine and record information about the state of the packet's connection. This information is recorded in a new state table entry created for the new connection. If there is not a firewall rule for this packet and it is not an attack, then the settings in the  Default Policy screen determine the action for this packet.4Based on the obtained state information, a firewall rule creates a temporary access list entry that is inserted at the beginning of the WAN interface's inbound extended access list. This temporary access list entry is designed to permit inbound packets of the same connection as the outbound packet just inspected.5The outbound packet is forwarded out through the interface.6Later, an inbound packet reaches the interface. This packet is part of the connection previously established with the outbound packet. The inbound packet is evaluated against the inbound access list, and is permitted because of the temporary access list entry previously created.7The packet is inspected by a firewall rule, and the connection's state table entry is updated as necessary. Based on the updated state information, the inbound extended access list
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 126temporary entries might be modified, in order to permit only packets that are valid for the current state of the connection.8Any additional inbound or outbound packets that belong to the connection are inspected to update the state table entry and to modify the temporary inbound access list entries as required, and are forwarded through the interface.9When the connection terminates or times out, the connection's state table entry is deleted and the connection's temporary inbound access list entries are deleted.10.5.2  Stateful Inspection and the PrestigeAdditional rules may be defined to extend or override the default rules. For example, a rule may be created which will:• Block all traffic of a certain type, such as IRC (Internet Relay Chat), from the LAN to the Internet.• Allow certain types of traffic from the Internet to specific hosts on the LAN.• Allow access to a Web server to everyone but competitors.• Restrict use of certain protocols, such as Telnet, to authorized users on the LAN.These custom rules work by evaluating the network traffic’s Source IP address, Destination IP address, IP protocol type, and comparing these to rules set by the administrator.Note: The ability to define firewall rules is a very powerful tool. Using custom rules, it is possible to disable all firewall protection or block all access to the Internet. Use extreme caution when creating or deleting firewall rules. Test changes after creating them to make sure they work correctly.Below is a brief technical description of how these connections are tracked. Connections may either be defined by the upper protocols (for instance, TCP), or by the Prestige itself (as with the "virtual connections" created for UDP and ICMP). 10.5.3  TCP SecurityThe Prestige uses state information embedded in TCP packets. The first packet of any new connection has its SYN flag set and its ACK flag cleared; these are "initiation" packets. All packets that do not have this flag structure are called "subsequent" packets, since they represent data that occurs later in the TCP stream. If an initiation packet originates on the WAN, this means that someone is trying to make a connection from the Internet into the LAN. Except in a few special cases (see "Upper Layer Protocols" shown next), these packets are dropped and logged.If an initiation packet originates on the LAN, this means that someone is trying to make a connection from the LAN to the Internet. Assuming that this is an acceptable part of the security policy (as is the case with the default policy), the connection will be allowed. A cache entry is added which includes connection information such as IP addresses, TCP ports, sequence numbers, etc.
P-660H/HW/W-T Series User’ Guide127 Chapter 10 FirewallsWhen the Prestige receives any subsequent packet (from the Internet or from the LAN), its connection information is extracted and checked against the cache. A packet is only allowed to pass through if it corresponds to a valid connection (that is, if it is a response to a connection which originated on the LAN).10.5.4  UDP/ICMP SecurityUDP and ICMP do not themselves contain any connection information (such as sequence numbers). However, at the very minimum, they contain an IP address pair (source and destination). UDP also contains port pairs, and ICMP has type and code information. All of this data can be analyzed in order to build "virtual connections" in the cache. For instance, any UDP packet that originates on the LAN will create a cache entry. Its IP address and port pairs will be stored. For a short period of time, UDP packets from the WAN that have matching IP and UDP information will be allowed back in through the firewall.A similar situation exists for ICMP, except that the Prestige is even more restrictive. Specifically, only outgoing echoes will allow incoming echo replies, outgoing address mask requests will allow incoming address mask replies, and outgoing timestamp requests will allow incoming timestamp replies. No other ICMP packets are allowed in through the firewall, simply because they are too dangerous and contain too little tracking information. For instance, ICMP redirect packets are never allowed in, since they could be used to reroute traffic through attacking machines. 10.5.5  Upper Layer ProtocolsSome higher layer protocols (such as FTP and RealAudio) utilize multiple network connections simultaneously. In general terms, they usually have a "control connection" which is used for sending commands between endpoints, and then "data connections" which are used for transmitting bulk information. Consider the FTP protocol. A user on the LAN opens a control connection to a server on the Internet and requests a file. At this point, the remote server will open a data connection from the Internet. For FTP to work properly, this connection must be allowed to pass through even though a connection from the Internet would normally be rejected.In order to achieve this, the Prestige inspects the application-level FTP data. Specifically, it searches for outgoing "PORT" commands, and when it sees these, it adds a cache entry for the anticipated data connection. This can be done safely, since the PORT command contains address and port information, which can be used to uniquely identify the connection.Any protocol that operates in this way must be supported on a case-by-case basis. You can use the web configurator’s Custom Ports feature to do this.10.6  Guidelines for Enhancing Security with Your Firewall• Change the default password via SMT or web configurator.
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 128• Limit who can telnet into your router. • Don't enable any local service (such as SNMP or NTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. • 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.10.6.1  Security In GeneralYou can never be too careful! Factors outside your firewall, filtering or NAT can cause security breaches. Below are some generalizations about what you can do to minimize them.• Encourage your company or organization to develop a comprehensive security plan. Good network administration takes into account what hackers can do and prepares against attacks. The best defense against hackers and crackers is information. Educate all employees about the importance of security and how to minimize risk. Produce lists like this one!• DSL or cable modem connections are “always-on” connections and are particularly vulnerable because they provide more opportunities for hackers to crack your system. Turn your computer off when not in use. • Never give out a password or any sensitive information to an unsolicited telephone call or e-mail.• Never e-mail sensitive information such as passwords, credit card information, etc., without encrypting the information first.• Never submit sensitive information via a web page unless the web site uses secure connections. You can identify a secure connection by looking for a small “key” icon on the bottom of your browser (Internet Explorer 3.02 or better or Netscape 3.0 or better). If a web site uses a secure connection, it is safe to submit information. Secure web transactions are quite difficult to crack.• Never reveal your IP address or other system networking information to people outside your company. Be careful of files e-mailed to you from strangers. One common way of getting BackOrifice on a system is to include it as a Trojan horse with other files.• Change your passwords regularly. Also, use passwords that are not easy to figure out. The most difficult passwords to crack are those with upper and lower case letters, numbers and a symbol such as % or #.• Upgrade your software regularly. Many older versions of software, especially web browsers, have well known security deficiencies. When you upgrade to the latest versions, you get the latest patches and fixes.• If you use “chat rooms” or IRC sessions, be careful with any information you reveal to strangers.• If your system starts exhibiting odd behavior, contact your ISP. Some hackers will set off hacks that cause your system to slowly become unstable or unusable.
P-660H/HW/W-T Series User’ Guide129 Chapter 10 Firewalls• Always shred confidential information, particularly about your computer, before throwing it away. Some hackers dig through the trash of companies or individuals for information that might help them in an attack.10.7  Packet Filtering Vs FirewallBelow are some comparisons between the Prestige’s filtering and firewall functions.10.7.1  Packet Filtering:• The router filters packets as they pass through the router’s interface according to the filter rules you designed.• Packet filtering is a powerful tool, yet can be complex to configure and maintain, especially if you need a chain of rules to filter a service.• Packet filtering only checks the header portion of an IP packet.10.7.1.1  When To Use Filtering• To block/allow LAN packets by their MAC addresses.• To block/allow special IP packets which are neither TCP nor UDP, nor ICMP packets.• To block/allow both inbound (WAN to LAN) and outbound (LAN to WAN) traffic between the specific inside host/network "A" and outside host/network "B". If the filter blocks the traffic from A to B, it also blocks the traffic from B to A. Filters can not distinguish traffic originating from an inside host or an outside host by IP address.• To block/allow IP trace route.10.7.2  Firewall• The firewall inspects packet contents as well as their source and destination addresses. Firewalls of this type employ an inspection module, applicable to all protocols, that understands data in the packet is intended for other layers, from the network layer (IP headers) up to the application layer.• The firewall performs stateful inspection. It takes into account the state of connections it handles so that, for example, a legitimate incoming packet can be matched with the outbound request for that packet and allowed in. Conversely, an incoming packet masquerading as a response to a nonexistent outbound request can be blocked.• The firewall uses session filtering, i.e., smart rules, that enhance the filtering process and control the network session rather than control individual packets in a session.• The firewall provides e-mail service to notify you of routine reports and when alerts occur.10.7.2.1  When To Use The Firewall• To prevent DoS attacks and prevent hackers cracking your network.
P-660H/HW/W-T Series User’ GuideChapter 10 Firewalls 130• A range of source and destination IP addresses as well as port numbers can be specified within one firewall rule making the firewall a better choice when complex rules are required.• To selectively block/allow inbound or outbound traffic between inside host/networks and outside host/networks. Remember that filters can not distinguish traffic originating from an inside host or an outside host by IP address.• The firewall performs better than filtering if you need to check many rules.• Use the firewall if you need routine e-mail reports about your system or need to be alerted when attacks occur.• The firewall can block specific URL traffic that might occur in the future. The URL can be saved in an Access Control List (ACL) database.

P-660H/HW/W-T Series User’ GuideChapter 11 Firewall Configuration 132CHAPTER 11Firewall ConfigurationThis chapter shows you how to enable and configure the Prestige firewall.11.1  Access MethodsThe web configurator is, by far, the most comprehensive firewall configuration tool your Prestige has to offer. For this reason, it is recommended that you configure your firewall using the web configurator. SMT screens allow you to activate the firewall. CLI commands provide limited configuration options and are only recommended for advanced users.11.2  Firewall Policies Overview  Firewall rules are grouped based on the direction of travel of packets to which they apply: Note: The LAN includes both the LAN port and the WLAN.By default, the Prestige’s stateful packet inspection allows packets traveling in the following directions:• LAN to LAN/ Router This allows computers on the LAN to manage the Prestige and communicate between networks or subnets connected to the LAN interface.• LAN to WANBy default, the Prestige’s stateful packet inspection blocks packets traveling in the following directions:•WAN to LAN•WAN to WAN/ Router This prevents computers on the WAN from using the Prestige as a gateway to communicate with other computers on the WAN and/or managing the Prestige.You may define additional rules and sets or modify existing ones but please exercise extreme caution in doing so.• LAN to LAN/ Router • WAN to LAN• LAN to WAN • WAN to WAN/ Router
P-660H/HW/W-T Series User’ Guide133 Chapter 11 Firewall ConfigurationNote: If you configure firewall rules without a good understanding of how they work, you might inadvertently introduce security risks to the firewall and to the protected network. Make sure you test your rules after you configure them.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 Prestige’s default rules. 11.3  Rule Logic Overview  Note: Study these points carefully before configuring rules.11.3.1  Rule ChecklistState the intent of the rule. For example, “This restricts all IRC access from the LAN to the Internet.” Or, “This allows a remote Lotus Notes server to synchronize over the Internet to an inside Notes server.”1Is the intent of the rule to forward or block traffic?2What direction of traffic does the rule apply to?3What IP services will be affected?4What computers on the LAN are to be affected (if any)?5What computers on the Internet will be affected? The more specific, the better. For example, if traffic is being allowed from the Internet to the LAN, it is better to allow only certain machines on the Internet to access the LAN.11.3.2  Security Ramifications1Once the logic of the rule has been defined, it is critical to consider the security ramifications created by the rule:2Does 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?3Is 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?
P-660H/HW/W-T Series User’ GuideChapter 11 Firewall Configuration 1344Does 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.5Does this rule conflict with any existing rules?6Once these questions have been answered, adding rules is simply a matter of plugging the information into the correct fields in the web configurator screens.11.3.3  Key Fields For Configuring Rules11.3.3.1  ActionShould the action be to Block or Forward? “Block” means the firewall silently discards the packet.11.3.3.2  ServiceSelect the service from the Service scrolling list box. If the service is not listed, it is necessary to first define it. See Section 11.10 on page 146 for more information on predefined services.11.3.3.3  Source AddressWhat is the connection’s source address; is it on the LAN, WAN? Is it a single IP, a range of IPs or a subnet?11.3.3.4  Destination AddressWhat is the connection’s destination address; is it on the LAN, WAN? Is it a single IP, a range of IPs or a subnet?11.4  Connection DirectionThis section describes examples for firewall rules for connections going from LAN to WAN and from WAN to LAN. LAN to LAN/ Router, WAN to WAN/ Router rules apply to packets coming in on the associated interface (LAN, WAN respectively). LAN to LAN/ Router means policies for LAN-to-Prestige (the policies for managing the Prestige through the LAN interface) and policies for LAN-to-LAN (the policies that control routing between two subnets on the LAN). Similarly, WAN to WAN/ Router polices apply in the same way to the WAN ports.11.4.1  LAN to WAN RulesThe default rule for LAN to WAN traffic is that all users on the LAN are allowed non-restricted access to the WAN. When you configure a LAN to WAN rule, you in essence want to limit some or all users from accessing certain services on the WAN. WAN to LAN Rules
P-660H/HW/W-T Series User’ Guide135 Chapter 11 Firewall ConfigurationThe default rule for WAN to LAN traffic blocks all incoming connections (WAN to LAN). If you wish to allow certain WAN users to have access to your LAN, you will need to create custom rules to allow it. 11.4.2  AlertsAlerts are reports on events, such as attacks, that you may want to know about right away. You can choose to generate an alert when an attack is detected in the Edit Rule screen (select the Send Alert Message to Administrator When Matched check box) or when a rule is matched in the Edit Rule screen. When an event generates an alert, a message can be immediately sent to an e-mail account that you specify in the Log Settings screen (see the chapter on logs).11.5  Configuring Default Firewall Policy   Click Firewall and then Default Policy to display the following screen. Activate the firewall by selecting the Firewall Enabled check box as seen in the following screen.Refer to Section 10.1 on page 118 for more information.

P-660H/HW/W-T Series User’ Guide149 Chapter 11 Firewall ConfigurationFigure 61   Firewall: Anti ProbingThe following table describes the labels in this screen.11.12  DoS Thresholds For DoS attacks, the Prestige 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.Refer to Section 11.12.3 on page 151 to configure thresholds.  Table 43   Firewall: Anti ProbingLABEL DESCRIPTIONRespond to PING onThe Prestige does not respond to any incoming Ping requests when Disable is selected.Select LAN to reply to incoming LAN Ping requests.Select WAN to reply to incoming WAN Ping requests. Otherwise select LAN & WAN to reply to both incoming LAN and WAN Ping requests. Do not respond to requests for unauthorized services.Select this option to prevent hackers from finding the Prestige by probing for unused ports. If you select this option, the Prestige will not respond to port request(s) for unused ports, thus leaving the unused ports and the Prestige unseen. By default this option is not selected and the Prestige will reply with an ICMP Port Unreachable packet for a port probe on its unused UDP ports, and a TCP Reset packet for a port probe on its unused TCP ports. Note that the probing packets must first traverse the Prestige 's firewall mechanism before reaching this anti-probing mechanism. Therefore if the firewall mechanism blocks a probing packet, the Prestige reacts based on the firewall policy, which by default, is to send a TCP reset packet for a blocked TCP packet. You can use the command "sys firewall tcprst rst [on|off]" to change this policy. When the firewall mechanism blocks a UDP packet, it drops the packet without sending a response packet.Back Click Back to return to the previous screen.

P-660H/HW/W-T Series User’ GuideChapter 11 Firewall Configuration 15011.12.1  Threshold ValuesTune these parameters when something is not working and after you have checked the firewall counters. These default values should work fine for most small offices. Factors influencing choices for threshold values are:• 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.• Network bandwidth. • Type of traffic for certain servers.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), then the default values should be reduced.You should make any changes to the threshold values before you continue configuring firewall rules. 11.12.2  Half-Open SessionsAn unusually high number of half-open sessions (either an absolute number or measured as the arrival rate) could indicate that a Denial of Service attack is occurring. For TCP, "half-open" means that the session has not reached the established state-the TCP three-way handshake has not yet been completed (see Figure 47 on page 122). For UDP, "half-open" means that the firewall has detected no return traffic.The Prestige measures both the total number of existing half-open sessions and the rate of session establishment attempts. Both TCP and UDP half-open sessions are counted in the total number and rate measurements. Measurements are made once a minute.When the number of existing half-open sessions rises above a threshold (max-incomplete high), the Prestige starts deleting half-open sessions as required to accommodate new connection requests. The Prestige continues to delete half-open requests as necessary, until the number of existing half-open sessions drops below another threshold (max-incomplete low).When the rate of new connection attempts rises above a threshold (one-minute high), the Prestige starts deleting half-open sessions as required to accommodate new connection requests. The Prestige continues to delete half-open sessions as necessary, until the rate of new connection attempts drops below another threshold (one-minute low). The rate is the number of new attempts detected in the last one-minute sample period.11.12.2.1  TCP Maximum Incomplete and Blocking TimeAn unusually high number of half-open sessions with the same destination host address could indicate that a Denial of Service attack is being launched against the host.
P-660H/HW/W-T Series User’ Guide151 Chapter 11 Firewall ConfigurationWhenever the number of half-open sessions with the same destination host address rises above a threshold (TCP Maximum Incomplete), the Prestige starts deleting half-open sessions according to one of the following methods:• If the Blocking Time timeout is 0 (the default), then the Prestige deletes the oldest existing half-open session for the host for every new connection request to the host. This ensures that the number of half-open sessions to a given host will never exceed the threshold.• If the Blocking Time timeout is greater than 0, then the Prestige blocks all new connection requests to the host giving the server time to handle the present connections. The Prestige continues to block all new connection requests until the Blocking Timeexpires. 11.12.3  Configuring Firewall Thresholds The Prestige also sends alerts whenever TCP Maximum Incomplete is exceeded. The global values specified for the threshold and timeout apply to all TCP connections. Click Firewall, and Threshold to bring up the next screen.Figure 62   Firewall: ThresholdThe following table describes the labels in this screen.

When the rate of new connection attempts rises above this number, the Prestige deletes half-open sessions as required to accommodate new connection attempts.100 half-open sessions per minute. The above numbers cause the Prestige to start deleting half-open sessions when more than 100 session establishment attempts have been detected in the last minute, and to stop deleting half-open sessions when fewer than 80 session establishment attempts have been detected in the last minute.MaximumIncomplete LowThis is the number of existing half-open sessions that causes the firewall to stop deleting half-open sessions. The Prestige continues to delete half-open requests as necessary, until the number of existing half-open sessions drops below this number.80 existing half-open sessions.MaximumIncomplete HighThis is the number of existing half-open sessions that causes the firewall to start deleting half-open sessions. When the number of existing half-open sessions rises above this number, the Prestige deletes half-open sessions as required to accommodate new connection requests. Do not set Maximum Incomplete High to lower than the current Maximum Incomplete Low number.100 existing half-open sessions. The above values causes the Prestige to start deleting half-open sessions when the number of existing half-open sessions rises above 100, and to stop deleting half-open sessions with the number of existing half-open sessions drops below 80.TCP Maximum Incomplete This is the number of existing half-open TCP sessions with the same destination host IP address that causes the firewall to start dropping half-open sessions to that same destination host IP address.

P-660H/HW/W-T Series User’ GuideChapter 13 Remote Management Configuration 158CHAPTER 13Remote ManagementConfigurationThis chapter provides information on configuring remote management.13.1  Remote Management Overview Remote management allows you to determine which services/protocols can access which Prestige interface (if any) from which computers.When you configure remote management to allow management from the WAN, you still need to configure a firewall rule to allow access.You may manage your Prestige from a remote location via:• Internet (WAN only)• ALL (LAN and WAN)• LAN only, • Neither (Disable).When you Choose WAN o n ly  or ALL (LAN & WAN), you still need to configure a firewall rule to allow access.To disable remote management of a service, select Disable in the corresponding Server Access field.You may only have one remote management session running at a time. The Prestige automatically disconnects a remote management session of lower priority when another remote management session of higher priority starts. The priorities for the different types of remote management sessions are as follows.1Telnet2HTTP13.1.1  Remote Management LimitationsRemote management over LAN or WAN will not work when:
P-660H/HW/W-T Series User’ Guide159 Chapter 13 Remote Management Configuration• A filter in SMT menu 3.1 (LAN) or in menu 11.5 (WAN) is applied to block a Telnet, FTP or Web service. • You have disabled that service in one of the remote management screens.• The IP address in the Secured Client IP field does not match the client IP address. If it does not match, the Prestige will disconnect the session immediately.• There is already another remote management session with an equal or higher priority running. You may only have one remote management session running at one time.• There is a firewall rule that blocks it.13.1.2  Remote Management and NATWhen NAT is enabled:• Use the Prestige’s WAN IP address when configuring from the WAN. • Use the Prestige’s LAN IP address when configuring from the LAN.13.1.3   System TimeoutThere is a default system management idle timeout of five minutes (three hundred seconds).

P-660H/HW/W-T Series User’ GuideChapter 14 Universal Plug-and-Play (UPnP) 162CHAPTER 14Universal Plug-and-Play (UPnP)This chapter introduces the UPnP feature in the web configurator.14.1  Introducing Universal Plug and Play Universal Plug and Play (UPnP) is a distributed, open networking standard that uses TCP/IP for simple peer-to-peer network connectivity between devices. A UPnP device can dynamically join a network, obtain an IP address, convey its capabilities and learn about other devices on the network. In turn, a device can leave a network smoothly and automatically when it is no longer in use.See Section 14.2.1 on page 163 for configuration instructions. 14.1.1  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. 14.1.2  NAT TraversalUPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:• Dynamic port mapping• Learning public IP addresses• Assigning lease times to mappingsWindows Messenger is an example of an application that supports NAT traversal and UPnP. See the NAT chapter for more information on NAT.
P-660H/HW/W-T Series User’ Guide163 Chapter 14 Universal Plug-and-Play (UPnP)14.1.3  Cautions with UPnPThe automated nature of NAT traversal applications in establishing their own services and opening firewall ports may present network security issues. Network information and configuration may also be obtained and modified by users in some network environments. All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 14.2  UPnP and ZyXELZyXEL has achieved UPnP certification from the Universal Plug and Play Forum Creates UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports IGD 1.0 (Internet Gateway Device). At the time of writing ZyXEL's UPnP implementation supports Windows Messenger 4.6 and 4.7 while Windows Messenger 5.0 and Xbox are still being tested.UPnP broadcasts are only allowed on the LAN.See later sections for examples of installing UPnP in Windows XP and Windows Me as well as an example of using UPnP in Windows.14.2.1  Configuring UPnP From the Site Map in the main menu, click UPnP under Advanced Setup to display the screen shown next.See Section 14.1 on page 162 for more information.

P-660H/HW/W-T Series User’ GuideChapter 16 Media Bandwidth Management Advanced Setup 182CHAPTER 16Media Bandwidth ManagementAdvanced SetupThis chapter describes bandwidth management with one level of child class.16.1  Media Bandwidth Management Overview Bandwidth management allows you to allocate an interface’s outgoing capacity to specific types of traffic. It can also help you make sure that the Prestige forwards certain types of traffic (especially real-time applications) with minimum delay. With the use of real-time applications such as Voice-over-IP (VoIP) increasing, the requirement for bandwidth allocation is also increasing. Bandwidth management addresses questions such as:• Who gets how much access to specific applications?• What priority level should you give to each type of traffic?• Which traffic must have guaranteed delivery?• How much bandwidth should be allotted to guarantee delivery?Bandwidth management also allows you to configure the allowed output for an interface to match what the network can handle. This helps reduce delays and dropped packets at the next routing device. For example, you can set the WAN interface speed to 1000kbps if the ADSL connection has an upstream speed of 1Mbps. All configuration screens display measurements in kbps (kilobits per second), but this User’s Guide also uses Mbps (megabits per second) for brevity’s sake.Refer to Section 16.9 on page 188 to enable and configure bandwidth on the interfaces. Refer to Section 16.10 on page 190 to configure bandwidth classes. Refer to Section 16.11 on page 194 to view bandwidth usage information. 16.2  Bandwidth Classes and FiltersUse bandwidth classes and child-classes to allocate specific amounts of bandwidth capacity (bandwidth budgets). Configure a bandwidth filter to define a bandwidth class (or child-class) based on a specific application and/or subnet. Use the Class Configuration screen (see Section 16.10 on page 190) to set up a bandwidth class’s name, bandwidth allotment, and
P-660H/HW/W-T Series User’ Guide183 Chapter 16 Media Bandwidth Management Advanced Setupbandwidth filter. You can configure up to one bandwidth filter per bandwidth class. You can also configure bandwidth classes without bandwidth filters. However, it is recommended that you configure child-classes with filters for any classes that you configure without filters. The Prestige leaves the bandwidth budget allocated and unused for a class that does not have a filter itself or child-classes with filters. View your configured bandwidth classes and child-classes in the Class Setup screen (see Section 16.10 on page 190 for details).The total of the configured bandwidth budgets for child-classes cannot exceed the configured bandwidth budget speed of the parent class. 16.3  Proportional Bandwidth AllocationBandwidth management allows you to define how much bandwidth each class gets; however, the actual bandwidth allotted to each class decreases or increases in proportion to actual available bandwidth. 16.4  Bandwidth Management Usage ExamplesThese examples show bandwidth management allotments on a WAN interface that is configured for 640Kbps.16.4.1  Application-based Bandwidth Management ExampleThe bandwidth classes in the following example are based solely on application. Each bandwidth class (VoIP, Web, FTP, E-mail and Video) is allotted 128kbps.Figure 87   Application-based Bandwidth Management Example16.4.2  Subnet-based Bandwidth Management ExampleThe following example uses bandwidth classes based solely on LAN subnets. Each bandwidth class (Subnet A and Subnet B) is allotted 320kbps.

P-660H/HW/W-T Series User’ Guide185 Chapter 16 Media Bandwidth Management Advanced Setup16.5  SchedulerThe scheduler divides up an interface’s bandwidth among the bandwidth classes. The Prestige has two types of scheduler: fairness-based and priority-based. 16.5.1  Priority-based SchedulerWith the priority-based scheduler, the Prestige forwards traffic from bandwidth classes according to the priorities that you assign to the bandwidth classes. The larger a bandwidth class’s priority number is, the higher the priority. Assign real-time applications (like those using audio or video) a higher priority number to provide smoother operation.16.5.2  Fairness-based SchedulerThe Prestige divides bandwidth equally among bandwidth classes when using the fairness-based scheduler; thus preventing one bandwidth class from using all of the interface’s bandwidth. 16.6  Maximize Bandwidth UsageThe maximize bandwidth usage option (see Section 16.7.1 on page 187) allows the Prestige to divide up any available bandwidth on the interface (including unallocated bandwidth and any allocated bandwidth that a class is not using) among the bandwidth classes that require more bandwidth. When you enable maximize bandwidth usage, the Prestige first makes sure that each bandwidth class gets up to its bandwidth allotment. Next, the Prestige divides up an interface’s available bandwidth (bandwidth that is unbudgeted or unused by the classes) depending on how many bandwidth classes require more bandwidth and on their priority levels. When only one class requires more bandwidth, the Prestige gives extra bandwidth to that class. When multiple classes require more bandwidth, the Prestige gives the highest priority classes the available bandwidth first (as much as they require, if there is enough available bandwidth), and then to lower priority classes if there is still bandwidth available. The Prestige distributes the available bandwidth equally among classes with the same priority level. 16.6.1  Reserving Bandwidth for Non-Bandwidth Class TrafficDo the following three steps to configure the Prestige to allow bandwidth for traffic that is not defined in a bandwidth filter.1Leave some of the interface’s bandwidth unbudgeted.2Do not enable the interface’s Maximize Bandwidth Usage option.3Do not enable bandwidth borrowing on the child-classes that have the root class as their parent (see Section 16.7 on page 187).
P-660H/HW/W-T Series User’ GuideChapter 16 Media Bandwidth Management Advanced Setup 18616.6.2  Maximize Bandwidth Usage ExampleHere is an example of a Prestige that has maximized bandwidth usage enabled on an interface. The first figure shows each bandwidth class’s bandwidth budget and priority. The classes are set up based on subnets. The interface is set to 10 Mbps. Each subnet is allocated 2 Mbps. The unbudgeted 2 Mbps allows traffic not defined in one of the bandwidth filters to go out when you do not select the maximize bandwidth option.Figure 90   Bandwidth Allotment ExampleThe following figure shows the bandwidth usage with the maximize bandwidth usage option enabled. The Prestige divides up the unbudgeted 2 Mbps among the classes that require more bandwidth. If the administration department only uses 1 Mbps of the budgeted 2 Mbps, the Prestige also divides the remaining 1 Mbps among the classes that require more bandwidth. Therefore, the Prestige divides a total of 3 Mbps total of unbudgeted and unused bandwidth among the classes that require more bandwidth. In this case, suppose that all of the classes except for the administration class need more bandwidth.• Each class gets up to its budgeted bandwidth. The administration class only uses 1 Mbps of its budgeted 2 Mbps. • Sales and Marketing are first to get extra bandwidth because they have the highest priority (6). If they each require 1.5 Mbps or more of extra bandwidth, the Prestige divides the total 3 Mbps total of unbudgeted and unused bandwidth equally between the sales and marketing departments (1.5 Mbps extra to each for a total of 3.5 Mbps for each) because they both have the highest priority level. • R&D requires more bandwidth but only gets its budgeted 2 Mbps because all of the unbudgeted and unused bandwidth goes to the higher priority sales and marketing classes. • The Prestige does not send any traffic that is not defined in the bandwidth filters because all of the unbudgeted bandwidth goes to the classes that need it.
P-660H/HW/W-T Series User’ Guide187 Chapter 16 Media Bandwidth Management Advanced SetupFigure 91   Maximize Bandwidth Usage Example16.7  Bandwidth BorrowingBandwidth borrowing allows a child-class to borrow unused bandwidth from its parent class, whereas maximize bandwidth usage allows bandwidth classes to borrow any unused or unbudgeted bandwidth on the whole interface.Enable bandwidth borrowing on a child-class to allow the child-class to use its parent class’s unused bandwidth. A parent class’s unused bandwidth is given to the highest-priority child-class that has bandwidth borrowing configured, first.The total of the bandwidth allotments for child-classes cannot exceed the bandwidth allotment of their parent class. The Prestige uses the scheduler to divide a parent class’s unused bandwidth among the child-classes. 16.7.1  Maximize Bandwidth Usage With Bandwidth BorrowingIf you configure both maximize bandwidth usage (on the interface) and bandwidth borrowing (on individual child-classes), the Prestige functions as follows.1The Prestige sends traffic according to each bandwidth class’s bandwidth budget.2The Prestige assigns a parent class’s unused bandwidth to its child-classes that have more traffic than their budgets and have bandwidth borrowing enabled. The Prestige gives priority to bandwidth child-classes of higher priority and treats bandwidth classes of the same priority equally.3The Prestige assigns any remaining unused or unbudgeted bandwidth on the interface to any bandwidth class that requires it. The Prestige gives priority to bandwidth classes of higher priority and treats bandwidth classes of the same level equally.
P-660H/HW/W-T Series User’ GuideChapter 16 Media Bandwidth Management Advanced Setup 1884The Prestige assigns any remaining unbudgeted bandwidth to traffic that does not match any of the bandwidth classes.16.8  The Main Media Bandwidth Management Screen Click Media Bandwidth Mgnt. to display the main Media Bandwidth Management screen as shown.

The higher the number, the higher the priority. The default setting is 3.Borrow bandwidth from parent class Select this option to allow a child-class to borrow bandwidth from its parent class if the parent class is not using up its bandwidth budget. Bandwidth borrowing is governed by the priority of the child-classes. That is, a child-class with the highest priority (7) is the first to borrow bandwidth from its parent class. Do not select this for the classes directly below the root class if you want to leave bandwidth available for other traffic types or you want to set the interface’s speed to match what the next device in network can handle (see the Speed field description in the Summary screen).Bandwidth FilterThe Prestige uses a bandwidth filter to identify the traffic that belongs to a bandwidth class.

P-660H/HW/W-T Series User’ GuideChapter 23 Internet Access 230CHAPTER 23Internet AccessThis chapter shows you how to configure the LAN and WAN of your Prestige for Internet access.23.1  Internet Access OverviewRefer to the chapters on the web configurator’s wizard, LAN and WAN screens for more background information on fields in the SMT screens covered in this chapter.23.2  IP PoliciesTraditionally, routing is based on the destination address only and the router takes the shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator. Policy-based routing is applied to incoming packets on a per interface basis, prior to the normal routing. Create policies using SMT menu 25 and apply them on the Prestige LAN and/or WAN interfaces using menus 3.2 (LAN) and 11.3 (WAN).23.3  IP AliasIP alias allows you to partition a physical network into different logical networks over the same Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the Prestige itself as the gateway for each LAN network.When you use IP alias, you can also configure firewall rules to control access between the LAN's logical networks (subnets).Note: Make sure that the subnets of the logical networks do not overlap.The following figure shows a LAN divided into subnets A, B, and C.

P-660H/HW/W-T Series User’ GuideChapter 24 Remote Node Configuration 236CHAPTER 24Remote Node ConfigurationThis chapter covers remote node configuration.24.1  Remote Node Setup OverviewThis section describes the protocol-independent parameters for a remote node. A remote node is required for placing calls to a remote gateway. A remote node represents both the remote gateway and the network behind it across a WAN connection. When you use menu 4 to set up Internet access, you are configuring one of the remote nodes.You first choose a remote node in Menu 11- Remote Node Setup. You can then edit that node’s profile in menu 11.1, as well as configure specific settings in three submenus: edit IP and bridge options in menu 11.3; edit ATM options in menu 11.6; and edit filter sets in menu 11.5.24.2 Remote Node SetupThis section describes the protocol-independent parameters for a remote node.24.2.1 Remote Node ProfileTo configure a remote node, follow these steps:1From the main menu, enter 11 to display Menu 11 - Remote Node Setup.2When menu 11 appears, as shown in the following figure, type the number of the remote node that you want to configure.
P-660H/HW/W-T Series User’ Guide237 Chapter 24 Remote Node ConfigurationFigure 124   Menu 11 Remote Node Setup24.2.2  Encapsulation and Multiplexing ScenariosFor Internet access you should use the encapsulation and multiplexing methods used by your ISP. Consult your telephone company for information on encapsulation and multiplexing methods for LAN-to-LAN applications, for example between a branch office and corporate headquarters. There must be prior agreement on encapsulation and multiplexing methods because they cannot be automatically determined. What method(s) you use also depends on how many VCs you have and how many different network protocols you need. The extra overhead that ENET ENCAP encapsulation entails makes it a poor choice in a LAN-to-LAN application. Here are some examples of more suitable combinations in such an application.24.2.2.1  Scenario 1: One VC, Multiple ProtocolsPPPoA (RFC-2364) encapsulation with VC-based multiplexing is the best combination because no extra protocol identifying headers are needed. The PPP protocol already contains this information.24.2.2.2  Scenario 2: One VC, One Protocol (IP)Selecting RFC-1483 encapsulation with VC-based multiplexing requires the least amount of overhead (0 octets). However, if there is a potential need for multiple protocol support in the future, it may be safer to select PPPoA encapsulation instead of RFC-1483, so you do not need to reconfigure either computer later.24.2.2.3  Scenario 3: Multiple VCsIf you have an equal number (or more) of VCs than the number of protocols, then select RFC-1483 encapsulation and VC-based multiplexing.

P-660H/HW/W-T Series User’ Guide239 Chapter 24 Remote Node Configuration24.2.3  Outgoing Authentication ProtocolFor obvious reasons, you should employ the strongest authentication protocol possible. However, some vendors’ implementation includes specific authentication protocol in the user profile. It will disconnect if the negotiated protocol is different from that in the user profile, even when the negotiated protocol is stronger than specified. If the peer disconnects right after a successful authentication, make sure that you specify the correct authentication protocol when connecting to such an implementation.PAP – accept PAP (Password Authentication Protocol) only.Route This field determines the protocol used in routing.

P-660H/HW/W-T Series User’ GuideChapter 25 Static Route Setup 246CHAPTER 25Static Route SetupThis chapter shows how to setup IP static routes.25.1  IP Static Route OverviewStatic routes tell the Prestige routing information that it cannot learn automatically through other means. This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is directly connected to a remote node.Each remote node specifies only the network to which the gateway is directly connected and the Prestige has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the following figure through remote node Router 1. However, the Prestige is unable to route a packet to network N3 because it does not know that there is a route through remote node Router 1 (via Router 2). The static routes allow you to tell the Prestige about the networks beyond the remote nodes.Figure 134   Sample Static Routing Topology25.2  ConfigurationTo configure an IP static route, use Menu 12 – Static Route Setup (shown next).

This is for identification purpose only.Active This field allows you to activate/deactivate this static route.Destination IP Address This parameter specifies the IP network address of the final destination. Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.IP Subnet Mask Type the subnet mask for this destination.Gateway IP Address Type the IP address of the gateway. The gateway is a router or switch on the same network segment as the device’s LAN or WAN port. The gateway helps forward packets to their destinations. Metric  Metric represents the cost of transmission for routing purposes. IP routing uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Type a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.Private This parameter determines if the Prestige will include the route to this remote node in its RIP broadcasts. If set to Yes, this route is kept private and is not included in RIP broadcasts. If No, the route to this remote node will be propagated to other hosts through RIP broadcasts.When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm or ESC to Cancel:”  to save your configuration, or press [ESC] at any time to cancel.

P-660H/HW/W-T Series User’ GuideChapter 26 Bridging Setup 250CHAPTER 26Bridging SetupThis chapter shows you how to configure the bridging parameters of your Prestige.26.1  Bridging in GeneralBridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while routing does it on the network layer (IP) address. Bridging allows the Prestige to transport packets of network layer protocols that it does not route, for example, SNA, from one network to another. The caveat is that, compared to routing, bridging generates more traffic for the same network layer protocol, and it also demands more CPU cycles and memory.For efficiency reasons, do not turn on bridging unless you need to support protocols other than IP on your network. For IP, enable the routing if you need it; do not bridge what the Prestige can route.26.2 Bridge Ethernet SetupBasically, all non-local packets are bridged to the WAN. Your Prestige does not support IPX.26.2.1 Remote Node Bridging SetupFollow the procedure in another section to configure the protocol-independent parameters in Menu 11.1 – Remote Node Profile. For bridging-related parameters, you need to configure Menu 11.3 – Remote Node Network Layer Options.1To setup Menu 11.3 – Remote Node Network Layer Options shown in the next figure, follow these steps:2In menu 11.1, make sure the Bridge field is set to Yes.

P-660H/HW/W-T Series User’ Guide259 Chapter 27 Network Address Translation (NAT)27.3.1.3  Ordering Your RulesOrdering your rules is important because the Prestige applies the rules in the order that you specify. When a rule matches the current packet, the Prestige takes the corresponding action and the remaining rules are ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up by that number of empty rules. For example, if you have already configured rules 1 to 6 in your current set and now you configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so as old rule 5 becomes rule 4, old rule 6 becomes rule 5 and old rule 7 becomes rule 6. You must press [ENTER] at the bottom of the screen to save the whole set. You must do this again if you make any changes to the set – including deleting a rule. No changes to the set take place until this action is taken. Selecting Edit in the Action field and then selecting a rule brings up the following menu, Menu 15.1.1.1 - Address Mapping Rule in which you can edit an individual rule and configure the Type,Local and Global Start/End IPs.An End IP address must be numerically greater than its corresponding IP Start address.Figure 147   Menu 15.1.1.1 Editing/Configuring an Individual Rule in a Set Table 92   Menu 15.1.1 First SetFIELD DESCRIPTIONSet Name Enter a name for this set of rules. This is a required field. If this field is left blank, the entire set will be deleted.Action The default is Edit.Edit means you want to edit a selected rule (see following field).

For this reason, it is recommended that you configure your firewall using the web configurator, see the following chapters for instructions. SMT screens allow you to activate the firewall and view firewall logs. 28.3 Enabling the FirewallFrom the main menu enter 21 to go to Menu 21 - Filter Set and Firewall Configuration todisplay the screen shown next.Enter option 2 in this menu to bring up the following screen. Press [SPACE BAR] and then [ENTER] to select Yes in the Active field to activate the firewall. The firewall must be active to protect against Denial of Service (DoS) attacks. Additional rules may be configured using the web configurator.

P-660H/HW/W-T Series User’ GuideChapter 29 Filter Configuration 272CHAPTER 29Filter ConfigurationThis chapter shows you how to create and apply filters.29.1  About FilteringYour Prestige uses filters to decide whether or not to allow passage of a data packet and/or to make a call. There are two types of filter applications: data filtering and call filtering. Filters are subdivided into device and protocol filters, which are discussed later.Data filtering screens data to determine if the packet should be allowed to pass. Data filters are divided into incoming and outgoing filters, depending on the direction of the packet relative to a port. Data filtering can be applied on either the WAN side or the Ethernet side. Call filtering is used to determine if a packet should be allowed to trigger a call.Outgoing packets must undergo data filtering before they encounter call filtering. Call filters are divided into two groups, the built-in call filters and user-defined call filters. Your Prestige has built-in call filters that prevent administrative, for example, RIP packets from triggering calls. These filters are always enabled and not accessible to you. Your Prestige applies the built-in filters first and then the user-defined call filters, if applicable, as shown next.Figure 164   Outgoing Packet Filtering ProcessTwo sets of factory filter rules have been configured in menu 21 to prevent NetBIOS traffic from triggering calls. A summary of their filter rules is shown in the figures that follow.The following figure illustrates the logic flow when executing a filter rule.
P-660H/HW/W-T Series User’ Guide273 Chapter 29 Filter ConfigurationFigure 165   Filter Rule ProcessYou can apply up to four filter sets to a particular port to block various types of packets. Because each filter set can have up to six rules, you can have a maximum of 24 rules active for a single port.For incoming packets, your Prestige applies data filters only. Packets are processed depending on whether a match is found. The following sections describe how to configure filter sets.29.1.1  The Filter Structure of the PrestigeA filter set consists of one or more filter rules.

You can configure up to twelve filter sets with six rules in each set, for a total of 72 filter rules in the system.

Parameters displayed for each type will be different. Choices are TCP/IP Filter Rule or Generic Filter Rule.Active Select Yes to activate or No to deactivate the filter rule.IP Protocol This is the upper layer protocol, for example, TCP is 6, UDP is 17 and ICMP is 1. The value must be between 0 and 255. A value of 0 matches ANY protocol.IP Source Route IP Source Route is an optional header that dictates the route an IP packet takes from its source to its destination. If Yes, the rule applies to any packet with an IP source route. The majority of IP packets do not have source route.Destination:IP Addr Type the destination IP address of the packet you want to filter. This field is ignored if it is 0.0.0.0.IP Mask Type the IP mask to apply to the Destination: IP Addr field.
P-660H/HW/W-T Series User’ GuideChapter 29 Filter Configuration 278The following figure illustrates the logic flow of an IP filter.Port # Type the destination port of the packets you want to filter.

P-660H/HW/W-T Series User’ Guide279 Chapter 29 Filter ConfigurationFigure 171   Executing an IP Filter29.4.2  Generic Filter RuleThis section shows you how to configure a generic filter rule. The purpose of generic rules is to allow you to filter non-IP packets. For IP, it is generally easier to use the IP rules directly.
P-660H/HW/W-T Series User’ GuideChapter 29 Filter Configuration 280For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP packet. You specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes. The Prestige applies the Mask (bit-wise ANDing) to the data portion before comparing the result against the Value to determine a match. The Mask and Value fields are specified in hexadecimal numbers. Note that it takes two hexadecimal digits to represent a byte, so if the length is 4, the value in either field will take 8 digits, for example, FFFFFFFF. To configure a generic rule select an empty filter set in menu 21, for example 5. Select Generic Filter Rule in the Filter Type field and press [ENTER] to open Menu 21.1.5.1 – Generic Filter Rule, as shown in the following figure.Figure 172   Menu 21.1.5.1 Generic Filter Rule The next table describes the fields in the Generic Filter Rule menu.Menu 21.1.5.1 - Generic Filter RuleFilter #: 5,1Filter Type= Generic Filter RuleActive= NoOffset= 0Length= 0Mask= N/AValue= N/AMore= No           Log= NoneAction Matched= Check Next RuleAction Not Matched= Check Next RulePress ENTER to Confirm or ESC to Cancel:Table 97   Menu 21.1.5.1 Generic Filter RuleFIELD DESCRIPTIONFilter # This is the filter set, filter rule coordinates, for instance, 2, 3 refers to the second filter set and the third rule of that set.Filter Type Press [SPACE BAR] and then [ENTER] to select a type of rule.

The range for this field is from 0 to 255.Length Type the byte count of the data portion in the packet that you want to compare. The range for this field is 0 to 8.Mask Type the mask (in Hexadecimal) to apply to the data portion before comparison.Value Type the value (in Hexadecimal) to compare with the data portion.More If Yes, a matching packet is passed to the next filter rule before an action is taken or else the packet is disposed of according to the action fields.If More is Yes, then Action Matched and Action Not Matched will be N/A.
P-660H/HW/W-T Series User’ Guide281 Chapter 29 Filter Configuration29.5  Filter Types and NAT There are two classes of filter rules, Generic Filter Device rules and Protocol Filter (TCP/IP)rules. Generic Filter rules act on the raw data from/to LAN and WAN. Protocol Filter rules act on IP packets.When NAT (Network Address Translation) is enabled, the inside IP address and port number are replaced on a connection-by-connection basis, which makes it impossible to know the exact address and port on the wire. Therefore, the Prestige applies the protocol filters to the “native” IP address and port number before NAT for outgoing packets and after NAT for incoming packets. On the other hand, the generic (or device) filters are applied to the raw packets that appear on the wire. They are applied at the point where the Prestige is receiving and sending the packets; for instance, the interface. The interface can be an Ethernet, or any other hardware port. The following figure illustrates this.Figure 173   Protocol and Device Filter Sets29.6  Example FilterLet’s look at an example to block outside users from telnetting into the Prestige. Log Select the logging option from the following:None – No packets will be logged.Action Matched – Only matching packets and rules will be logged.Action Not Matched – Only packets that do not match the rule parameters will be logged.Both – All packets will be logged.Action MatchedSelect the action for a matching packet.

P-660H/HW/W-T Series User’ GuideChapter 30 SNMP Configuration 286CHAPTER 30SNMP ConfigurationThis chapter explains SNMP Configuration menu 22.30.1  About SNMPSimple Network Management Protocol (SNMP) is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP agent functionality, which allows a manager station to manage and monitor the Prestige through the network. The Prestige supports SNMP version one (SNMPv1) and version two c (SNMPv2c). The next figure illustrates an SNMP management operation. SNMP is only available if TCP/IP is configured.Figure 179   SNMP Management ModelAn SNMP managed network consists of two main components: agents and a manager. An agent is a management software module that resides in a managed device (the Prestige). 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.
P-660H/HW/W-T Series User’ Guide287 Chapter 30 SNMP ConfigurationThe managed devices contain object variables/managed objects that define each piece of information to be collected about a device. Examples of variables include the 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.SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a request and the agent returns responses using the following protocol operations:• Get - Allows the manager to retrieve an object variable from the agent. • GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent. In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get operation, followed by a series of GetNext operations. • Set - Allows the manager to set values for object variables within an agent. • Trap - Used by the agent to inform the manager of some events.30.2   Supported MIBsThe Prestige supports RFC-1215 and MIB II as defined in RFC-1213 as well as ZyXEL private MIBs. The focus of the MIBs is to let administrators collect statistic data and monitor status and performance.30.3  SNMP ConfigurationTo configure SNMP, select option 22 from the main menu to open Menu 22 — SNMP Configuration as shown next. The “community” for Get, Set and Trap fields is SNMP terminology for password.

Trusted Host If you enter a trusted host, your Prestige will only respond to SNMP messages from this address. A blank (default) field means your Prestige will respond to all SNMP messages it receives, regardless of source.Trap:Community Type the trap community, which is the password sent with each trap to the SNMP manager. Destination Type the IP address of the station to send your SNMP traps to.When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm or ESC to Cancel:”  to save your configuration, or press [ESC] at any time to cancel.Table 100   SNMP TrapsTRAP # TRAP NAME DESCRIPTION1coldStart (defined in RFC-1215)A trap is sent after booting (power on).2warmStart (defined in RFC-1215)A trap is sent after booting (software reboot).3linkDown (defined in RFC-1215)A trap is sent with the port number when any of the links are down.

P-660H/HW/W-T Series User’ Guide293 Chapter 31 System SecurityTable 103   Menu 23.4 System Security: IEEE 802.1xFIELD DESCRIPTIONWireless Port ControlPress [SPACE BAR] and select a security mode for the wireless LAN access. Select No Authentication Required to allow any wireless stations access to your wired network without entering usernames and passwords. This is the default setting.Selecting Authentication Required means wireless stations have to enter usernames and passwords before access to the wired network is allowed. Select No Access Allowed to block all wireless stations access to the wired network.The following fields are not available when you select No Authentication Requiredor No Access Allowed.ReAuthentica-tion Timer(in second)Specify how often a client has to re-enter username and password to stay connected to the wired network. This field is activated only when you select Authentication Required in the Wireless Port Control field. Enter a time interval between 10 and 9999 (in seconds). The default time interval is 1800 seconds (or 30 minutes). Idle Timeout (in second)The Prestige automatically disconnects a client from the wired network after a period of inactivity. The client needs to enter the username and password again before access to the wired network is allowed. This field is activated only when you select Authentication Required in the Wireless Port Control field. The default time interval is 3600 seconds (or 1 hour).Key Management ProtocolPress [SPACE BAR] to select 802.1x,WPA or WPA-PSK and press [ENTER].Dynamic WEP Key ExchangeThis field is activated only when you select Authentication Required in the Wireless Port Control field. Also set the Authentication Databases field to RADIUS Only. Local user database may not be used.  Select Disable to allow wireless stations to communicate with the access points without using Dynamic WEP Key Exchange. Select 64-bit WEP or 128-bit WEP to enable data encryption. Up to 32 stations can access the Prestige when you configure Dynamic WEP Key Exchange. This field is not available when you set Key Management Protocol to WPA or WPA-PSK.PSK Type a pre-shared key from 8 to 63 case-sensitive ASCII characters (including spaces and symbols) when you select WPA-PSK in the Key Management Protocol field. WPA Mixed ModeSelect Enable to activate WPA mixed mode. Otherwise, select Disable and configure Group Data Privacy field.Data Privacy for Broadcast/ Multicast packetsThis field allows you to choose TKIP (recommended) or WEP for broadcast and multicast (“group”) traffic if the Key Management Protocol is WPA and WPA Mixed Mode is disabled. WEP is used automatically if you have enabled WPA Mixed Mode.All unicast traffic is automatically encrypted by TKIP when WPA or WPA-PSK Key Management Protocol is selected.WPA Broadcast/ Multicast Key Update TimerThe WPA Broadcast/Multicast Key Update Timer is the rate at which the AP (if using WPA-PSK key management) or RADIUS server (if using WPA key management) sends a new group key out to all clients. The re-keying process is the WPA equivalent of automatically changing the WEP key for an AP and all stations in a WLAN on a periodic basis. Setting of the WPA Broadcast/Multicast Key Update Timer is also supported in WPA-PSK mode. The Prestige default is 1800 seconds (30 minutes).
P-660H/HW/W-T Series User’ GuideChapter 31 System Security 294Once you enable user authentication, you need to specify an external RADIUS server or create local user accounts on the Prestige for authentication. 31.2  Creating User Accounts on the Prestige By storing user profiles locally, your Prestige is able to authenticate wireless users without interacting with a network RADIUS server. Follow the steps below to set up user profiles on your Prestige.1From the main menu, enter 14 to display Menu 14 - Dial-in User Setup.Authentication DatabasesThe authentication database contains wireless station login information. The local user database is the built-in database on the Prestige. The RADIUS is an external server. Use this field to decide which database the Prestige should use (first) to authenticate a wireless station.Before you specify the priority, make sure you have set up the corresponding database correctly first. When you configure Key Management Protocol to WPA, the Authentication Databases must be RADIUS Only. You can only use the Local User Databasewith 802.1x Key Management Protocol.Select Local User Database Only to have the Prestige just check the built-in user database on the Prestige for a wireless station's username and password. Select RADIUS Only to have the Prestige just check the user database on the specified RADIUS server for a wireless station's username and password. Select Local first, then RADIUS to have the Prestige first check the user database on the Prestige for a wireless station's username and password. If the user name is not found, the Prestige then checks the user database on the specified RADIUS server.Select RADIUS first, then Local to have the Prestige first check the user database on the specified RADIUS server for a wireless station's username and password. If the Prestige cannot reach the RADIUS server, the Prestige then checks the local user database on the Prestige. When the user name is not found or password does not match in the RADIUS server, the Prestige will not check the local user database and the authentication fails.When you have completed this menu, press [ENTER] at the prompt “Press ENTER to Confirm or ESC to Cancel:”  to save your configuration, or press [ESC] at any time to cancel.Table 103   Menu 23.4 System Security: IEEE 802.1x (continued)FIELD DESCRIPTION

P-660H/HW/W-T Series User’ GuideChapter 33 Firmware and Configuration File Maintenance 306CHAPTER 33Firmware and Configuration FileMaintenanceThis chapter tells you how to backup and restore your configuration file as well as upload new firmware and configuration files.33.1  Filename ConventionsThe configuration file (often called the romfile or rom-0) contains the factory default settings in the menus such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a “rom” filename extension. Once you have customized the Prestige's settings, they can be saved back to your computer under a filename of your choosing.ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware and has a “bin” filename extension. With many FTP and TFTP clients, the filenames are similar to those seen next. Note: Only use firmware for your Prestige’s specific model. Refer to the label on the bottom of your Prestige.ftp> put firmware.bin rasThis is a sample FTP session showing the transfer of the computer file "firmware.bin" to the Prestige.ftp> get rom-0 config.cfgThis is a sample FTP session saving the current configuration to the computer file “config.cfg”.If your (T)FTP client does not allow you to have a destination filename different than the source, you will need to rename them as the Prestige only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies of both files for later use.
P-660H/HW/W-T Series User’ Guide307 Chapter 33 Firmware and Configuration File MaintenanceThe following table is a summary. Please note that the internal filename refers to the filename on the Prestige and the external filename refers to the filename not on the Prestige, that is, on your computer, local network or FTP site and so the name (but not the extension) may vary. After uploading new firmware, see the ZyNOS F/W Version field in Menu 24.2.1 – System Maintenance – Information to confirm that you have uploaded the correct firmware version. The AT command is the command you enter after you press “y” when prompted in the SMT menu to go into debug mode.33.2  Backup ConfigurationOption 5 from Menu 24 – System Maintenance allows you to backup the current Prestige configuration to your computer. Backup is highly recommended once your Prestige is functioning properly. FTP is the preferred methods for backing up your current configuration to your computer since they are faster. Any serial communications program should work fine; however, you must use Xmodem protocol to perform the download/upload and you don’t have to rename the files.Please note that terms “download” and “upload” are relative to the computer. Download means to transfer from the Prestige to the computer, while upload means from your computer to the Prestige.33.2.1  Backup ConfigurationFollow the instructions as shown in the next screen. Table 109   Filename ConventionsFILE TYPE INTERNAL NAME EXTERNAL NAME  DESCRIPTIONConfiguration FileRom-0 This is the configuration filename on the Prestige.

P-660H/HW/W-T Series User’ GuideChapter 33 Firmware and Configuration File Maintenance 31033.2.6  Backup Configuration Using TFTPThe Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial File Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.To use TFTP, your computer must have both telnet and TFTP clients. To backup the configuration file, follow the procedure shown next.1Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not have any security checks, the Prestige records the IP address of the telnet client and accepts TFTP requests only from this address.2Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – SystemMaintenance.3Enter command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not be interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout (default) when the file transfer is complete.4Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to binary before starting data transfer.5Use the TFTP client (see the example below) to transfer files between the Prestige and the computer. The file name for the configuration file is “rom-0” (rom-zero, not capital o).Note that the telnet connection must be active and the SMT in CI mode before and during the TFTP transfer. For details on TFTP commands (see following example), please consult the documentation of your TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer and “binary” to set binary transfer mode.33.2.7  TFTP Command ExampleThe following is an example TFTP command:tftp [-i] host get rom-0 config.romwhere “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the Prestige IP address, “get” transfers the file source on the Prestige (rom-0,name of the configuration file on the Prestige) to the file destination on the computer and renames it config.rom.33.2.8  GUI-based TFTP ClientsThe following table describes some of the fields that you may see in GUI-based TFTP clients.

The Prestige automatically logs you out if the management session remains idle for longer than this timeout period. The management session does not time out when it is continuously updating the status in menu 24.1 or when sys stdio has been changed on the command line.

P-660H/HW/W-T Series User’ GuideChapter 36 IP Policy Routing 328CHAPTER 36IP Policy RoutingThis chapter covers setting and applying policies used for IP routing.36.1  IP Policy Routing OverviewTraditionally, routing is based on the destination address only and the IAD takes the shortest path to forward a packet. IP Routing Policy (IPPR) provides a mechanism to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator. Policy-based routing is applied to incoming packets on a per interface basis, prior to the normal routing.36.2  Benefits of IP Policy RoutingSource-Based Routing – Network administrators can use policy-based routing to direct traffic from different users through different connections.Quality of Service (QoS) – Organizations can differentiate traffic by setting the precedence or TOS (Type of Service)  values in the IP header at the periphery of the network to enable the backbone to prioritize traffic.Cost Savings – IPPR allows organizations to distribute interactive traffic on high-bandwidth, high-cost paths while using low-cost paths for batch traffic.Load Sharing – Network administrators can use IPPR to distribute traffic among multiple paths.36.3  Routing PolicyIndividual routing policies are used as part of the overall IPPR process. A policy defines the matching criteria and the action to take when a packet meets the criteria. The action is taken only when all the criteria are met. The criteria includes the source address and port, IP protocol (ICMP, UDP, TCP, etc.), destination address and port, TOS and precedence (fields in the IP header) and length. The inclusion of length criterion is to differentiate between interactive and bulk traffic. Interactive applications, for example, telnet, tend to have short packets, while bulk traffic, for example, file transfer, tends to have large packets.The actions that can be taken include:
P-660H/HW/W-T Series User’ Guide329 Chapter 36 IP Policy Routing• routing the packet to a different gateway (and hence the outgoing interface).• setting the TOS and precedence fields in the IP header.IPPR follows the existing packet filtering facility of RAS in style and in implementation. The policies are divided into sets, where related policies are grouped together. A user defines the policies before applying them to an interface or a remote node, in the same fashion as the filters. There are 12 policy sets with six policies in each set.36.4  IP Routing Policy SetupMenu 25 shows all the policies defined.Figure 211   Menu 25 IP Routing Policy SetupTo setup a routing policy, perform the following procedures:1Type 25 in the main menu to open Menu 25 – IP Routing Policy Setup.2Type the index of the policy set you want to configure to open Menu 25.1 – IP Routing Policy Setup.Menu 25.1 shows the summary of a policy set, including the criteria and the action of a single policy, and whether a policy is active or not. Each policy contains two lines. The former part is the criteria of the incoming packet and the latter is the action. Between these two parts, separator “|” means the action is taken on criteria matched and separator “=” means the action is taken on criteria not matched.

This feature is similar to the scheduler in a videocassette recorder (you can specify a time period for the VCR to record). You can apply up to 4 schedule sets in Menu 11.1 — Remote Node Profile.  From the main menu, enter 26 to access Menu 26 — Schedule Setup as shown next. Figure 220   Menu 26 Schedule SetupLower numbered sets take precedence over higher numbered sets thereby avoiding scheduling conflicts. For example, if sets 1, 2 ,3 and 4 in are applied in the remote node then set 1 will take precedence over set 2, 3 and 4 as the Prestige, by default, applies the lowest numbered set first.  Set 2 will take precedence over set 3 and 4, and so on.You can design up to 12 schedule sets but you can only apply up to four schedule sets for a remote node.To delete a schedule set, enter the set number and press [SPACE BAR] and then [ENTER](or delete) in the Edit Name field.Menu 26 - Schedule Setup   Schedule   Set #          Name                  Set #          Name   ------  -----------------            ------  -----------------     1      _______________               7      _______________     2      _______________               8      _______________     3      _______________               9      _______________     4      _______________              10      _______________     5      _______________              11      _______________     6      _______________              12      _______________Enter Schedule Set Number to Configure= 0Edit Name= N/APress ENTER to Confirm or ESC to Cancel:

P-660H/HW/W-T Series User’ GuideAppendix D 376Appendix DIP SubnettingIP Addressing Routers “route” based on the network number. The router that delivers the data packet to the correct destination host uses the host ID. IP ClassesAn IP address is made up of four octets (eight bits), written in dotted decimal notation, for example, 192.168.1.1. IP addresses are categorized into different classes. The class of an address depends on the value of its first octet. • Class “A” addresses have a 0 in the left most bit. In a class “A” address the first octet is the network number and the remaining three octets make up the host ID.• Class “B” addresses have a 1 in the left most bit and a 0 in the next left most bit. In a class “B” address the first two octets make up the network number and the two remaining octets make up the host ID.• Class “C” addresses begin (starting from the left) with 1 1 0. In a class “C” address the first three octets make up the network number and the last octet is the host ID.• Class “D” addresses begin with 1 1 1 0. Class “D” addresses are used for multicasting. (There is also a class “E” address. It is reserved for future use.) Note: Host IDs of all zeros or all ones are not allowed.Therefore:A class “C” network (8 host bits) can have 28 –2 or 254 hosts. A class “B” address (16 host bits) can have 216 –2 or 65534 hosts. A class “A” address (24 host bits) can have 224 –2 hosts (approximately 16 million hosts). Table 124   Classes of IP AddressesIP ADDRESS: OCTET 1 OCTET 2 OCTET 3 OCTET 4Class A 0Network number Host ID Host ID Host IDClass B 10 Network number Network number Host ID Host IDClass C 110 Network number Network number Network number Host ID
P-660H/HW/W-T Series User’ Guide377 Appendix DSince the first octet of a class “A” IP address must contain a “0”, the first octet of a class “A” address can have a value of 0 to 127. Similarly the first octet of a class “B” must begin with “10”, therefore the first octet of a class “B” address has a valid range of 128 to 191. The first octet of a class “C” address begins with “110”, and therefore has a range of 192 to 223. Subnet MasksA subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). A subnet mask has 32  is a “1” then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit in the IP address is part of the host ID. Subnet masks are expressed in dotted decimal notation just as IP addresses are. The “natural” masks for class A, B and C IP addresses are as follows.SubnettingWith subnetting, the class arrangement of an IP address is ignored. For example, a class C address no longer has to have 24 bits of network number and 8 bits of host ID. With subnetting, some of the host ID bits are converted into network number bits. By convention, subnet masks always consist of a continuous sequence of ones beginning from the left most bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.Table 125   Allowed IP Address Range By ClassCLASS ALLOWED RANGE OF FIRST OCTET (BINARY)ALLOWED RANGE OF FIRST OCTET (DECIMAL)Class A 00000000 to 01111111 0 to 127Class B 10000000 to 10111111 128 to 191Class C 11000000 to 11011111 192 to 223Class D 11100000 to 11101111 224 to 239Table 126    “Natural” MasksCLASS NATURAL MASKA255.0.0.0B255.255.0.0C255.255.255.0
P-660H/HW/W-T Series User’ GuideAppendix D 378Since the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with mask 255.255.255.128. The following table shows all possible subnet masks for a class “C” address using both notations.The first mask shown is the class “C” natural mask. Normally if no mask is specified it is understood that the natural mask is being used.Example: Two SubnetsAs an example, you have a class “C” address 192.168.1.0 with subnet mask of 255.255.255.0. The first three octets of the address make up the network number (class “C”). You want to have two separate networks.Divide the network 192.168.1.0 into two separate subnets by converting one of the host ID bits of the IP address to a network number bit. The “borrowed” host ID bit can be either “0” or “1” thus giving two subnets; 192.168.1.0 with mask 255.255.255.128 and 192.168.1.128 with mask 255.255.255.128.Table 127   Alternative Subnet Mask NotationSUBNET MASK SUBNET MASK “1” BITS LAST OCTET BIT VALUE255.255.255.0 /24 0000 0000255.255.255.128 /25 1000 0000255.255.255.192 /26 1100 0000255.255.255.224 /27 1110 0000255.255.255.240 /28 1111 0000255.255.255.248 /29 1111 1000255.255.255.252 /30 1111 1100Table 128   Two Subnets ExampleIP/SUBNET MASK NETWORK NUMBER HOST IDIP Address 192.168.1. 0IP Address (Binary) 11000000.10101000.00000001. 00000000Subnet Mask 255.255.255. 0Subnet Mask (Binary) 11111111.11111111.11111111. 00000000
P-660H/HW/W-T Series User’ Guide379 Appendix DNote: In the following charts, shaded/bolded last octet bit values indicate host ID bits “borrowed” to form network ID bits. The number of “borrowed” host ID bits determines the number of subnets you can have. The remaining number of host ID bits  (after “borrowing”) determines the number of hosts you can have on each subnet.The remaining 7 bits determine the number of hosts each subnet can have. Host IDs of all zeros represent the subnet itself and host IDs of all ones are the broadcast address for that subnet, so the actual number of hosts available on each subnet in the example above is 27 – 2 or 126 hosts for each subnet.192.168.1.0 with mask 255.255.255.128 is the subnet itself, and 192.168.1.127 with mask 255.255.255.128 is the directed broadcast address for the first subnet. Therefore, the lowest IP address that can be assigned to an actual host for the first subnet is 192.168.1.1 and the highest is 192.168.1.126. Similarly the host ID range for the second subnet is 192.168.1.129 to 192.168.1.254.Table 129   Subnet 1IP/SUBNET MASK NETWORK NUMBER LAST OCTET BIT VALUEIP Address 192.168.1. 0IP Address (Binary) 11000000.10101000.00000001. 00000000Subnet Mask 255.255.255. 128Subnet Mask (Binary) 11111111.11111111.11111111. 10000000Subnet Address: 192.168.1.0 Lowest Host ID: 192.168.1.1Broadcast Address: 192.168.1.127Highest Host ID: 192.168.1.126Table 130   Subnet 2IP/SUBNET MASK NETWORK NUMBER LAST OCTET BIT VALUEIP Address 192.168.1. 128IP Address (Binary) 11000000.10101000.00000001. 10000000Subnet Mask 255.255.255. 128Subnet Mask (Binary) 11111111.11111111.11111111. 10000000Subnet Address: 192.168.1.128Lowest Host ID: 192.168.1.129Broadcast Address: 192.168.1.255Highest Host ID: 192.168.1.254

Similarly to divide a class “C” address into four subnets, you need to “borrow” two host ID bits to give four possible combinations of 00, 01, 10 and 11. The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192. Each subnet contains 6 host ID bits, giving 26-2 or 62 hosts for each subnet (all 0’s is the subnet itself, all 1’s is the broadcast address on the subnet).

When you start up your Prestige, you are given a choice to go into debug mode by pressing a key at the prompt shown in the following screen. In debug mode you have access to a series of boot module commands, for example ATUR (for uploading firmware) and ATLC (for uploading the configuration file). These are already discussed in the Firmware and Configuration File Maintenance chapter.Figure 256   Option to Enter Debug ModeEnter ATHE to view all available Prestige boot module commands as shown in the next screen. ATBAx allows you to change the console port speed. The x denotes the number preceding the colon to give the console port speed following the colon in the list of numbers that follows; for example ATBA3 will give a console port speed of 9.6 Kbps. ATSE displays the seed that is used to generate a password to turn on the debug flag in the firmware. The ATSH command shows product related information such as boot module version, vendor name, product model, RAS code revision, etc. ATGO allows you to continue booting the system. Most other commands aid in advanced troubleshooting and should only be used by qualified engineers.

This allows simultaneous Internet access and telephone service on the same line. A splitter also eliminates the destructive interference conditions caused by telephone sets. Install the POTS splitter at the point where the telephone line enters your residence, as shown in the following figure.Figure 258   Connecting a POTS Splitter1Connect the side labeled “Phone” to your telephone.2Connect the side labeled “Modem” to your Prestige.3Connect the side labeled “Line” to the telephone wall jack.Telephone MicrofiltersTelephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter, for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice transmissions. The use of a telephone microfilter is optional.

P-660H/HW/W-T Series User’ GuideAppendix J 402Appendix JPPPoEPPPoE in ActionAn ADSL modem bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC (Permanent Virtual Circuit) which connects to a DSL Access Concentrator where the PPP session terminates (see Figure 261 on page 403). One PVC can support any number of PPP sessions from your LAN. PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.Benefits of PPPoEPPPoE offers the following benefits:It provides you with a familiar dial-up networking (DUN) user interface.It lessens the burden on the carriers of provisioning virtual circuits all the way to the ISP on multiple switches for thousands of users.  For GSTN (PSTN and ISDN), the switching fabric is already in place.It allows the ISP to use the existing dial-up model to authenticate and (optionally) to provide differentiated services.Traditional Dial-up ScenarioThe following diagram depicts a typical hardware configuration where the computers use traditional dial-up networking.
P-660H/HW/W-T Series User’ Guide403 Appendix JFigure 261   Single-Computer per Router Hardware ConfigurationHow PPPoE WorksThe PPPoE driver makes the Ethernet appear as a serial link to the computer and the computer runs PPP over it, while the modem bridges the Ethernet frames to the Access Concentrator (AC).  Between the AC and an ISP, the AC is acting as a L2TP (Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator) and tunnels the PPP frames to the ISP.  The L2TP tunnel is capable of carrying multiple PPP sessions.With PPPoE, the VC (Virtual Circuit) is equivalent to the dial-up connection and is between the modem and the AC, as opposed to all the way to the ISP.  However, the PPP negotiation is between the computer and the ISP. Prestige as a PPPoE ClientWhen using the Prestige as a PPPoE client, the computers on the LAN see only Ethernet and are not aware of PPPoE. This alleviates the administrator from having to manage the PPPoE clients on the individual computers.Figure 262   Prestige as a PPPoE Client

P-660H/HW/W-T Series User’ GuideAppendix L 420Appendix LWireless LANsWireless LAN TopologiesThis section discusses ad-hoc and infrastructure wireless LAN topologies.Ad-hoc Wireless LAN ConfigurationThe simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN. Figure 265   Peer-to-Peer Communication in an Ad-hoc NetworkBSSA Basic Service Set (BSS) exists when all communications between wireless stations or between a wireless station and a wired network client go through one access point (AP). Intra-BSS traffic is traffic between wireless stations in the BSS. When Intra-BSS is enabled, wireless station A and B can access the wired network and communicate with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.
P-660H/HW/W-T Series User’ Guide421 Appendix LFigure 266   Basic Service SetESSAn Extended Service Set (ESS) consists of a series of overlapping BSSs, each containing an access point, with each access point connected together by a wired network. This wired connection between APs is called a Distribution System (DS).This type of wireless LAN topology is called an Infrastructure WLAN. The Access Points not only provide communication with the wired network but also mediate wireless network traffic in the immediate neighborhood. An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate.
P-660H/HW/W-T Series User’ GuideAppendix L 422Figure 267   Infrastructure WLANChannelA channel is the radio frequency(ies) used by IEEE 802.11a/b/g wireless devices. Channels available depend on your geographical area. You may have a choice of channels (for your region) so you should use a different channel than an adjacent AP (access point) to reduce interference. Interference occurs when radio signals from different access points overlap causing interference and degrading performance.Adjacent channels partially overlap however. To avoid interference due to overlap, your AP should be on a channel at least five channels away from a channel that an adjacent AP is using. For example, if your region has 11 channels and an adjacent AP is using channel 1, then you need to select a channel between 6 or 11.RTS/CTSA hidden node occurs when two stations are within range of the same access point, but are not within range of each other. The following figure illustrates a hidden node. Both stations (STA) are within range of the access point (AP) or wireless gateway, but out-of-range of each other, so they cannot "hear" each other, that is they do not know if the channel is currently being used. Therefore, they are considered hidden from each other.
P-660H/HW/W-T Series User’ Guide423 Appendix LFigure 268    RTS/CTSWhen station A sends data to the AP, it might not know that the station B is already using the channel. If these two stations send data at the same time, collisions may occur when both sets of data arrive at the AP at the same time, resulting in a loss of messages for both stations.RTS/CTS is designed to prevent collisions due to hidden nodes. An RTS/CTS defines the biggest size data frame you can send before an RTS (Request To Send)/CTS (Clear to Send) handshake is invoked.When a data frame exceeds the RTS/CTS value you set (between 0 to 2432 bytes), the station that wants to transmit this frame must first send an RTS (Request To Send) message to the AP for permission to send it. The AP then responds with a CTS (Clear to Send) message to all other stations within its range to notify them to defer their transmission. It also reserves and confirms with the requesting station the time frame for the requested transmission.Stations can send frames smaller than the specified RTS/CTS directly to the AP without the RTS (Request To Send)/CTS (Clear to Send) handshake. You should only configure RTS/CTS if the possibility of hidden nodes exists on your network and the "cost" of resending large frames is more than the extra network overhead involved in the RTS (Request To Send)/CTS (Clear to Send) handshake. If the RTS/CTS value is greater than the Fragmentation Threshold value (see next), then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size. Note: Enabling the RTS Threshold causes redundant network overhead that could negatively affect the throughput performance instead of providing a remedy.Fragmentation ThresholdAFragmentation Threshold is the maximum data fragment size (between 256 and 2432 bytes) that can be sent in the wireless network before the AP will fragment the packet into smaller data frames.
P-660H/HW/W-T Series User’ GuideAppendix L 424A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.Preamble TypeA preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short.Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless stations support it. Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless stations support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the AP and the wireless stations and to provide more reliable communication in ‘noisy’ networks. Select Dynamic to have the AP automatically use short preamble when all wireless stations support it, otherwise the AP uses long preamble.Note: The AP and the wireless stations MUST use the same preamble mode in order to communicate.IEEE 802.11g Wireless LANIEEE 802.11g is fully compatible with the IEEE 802.11b standard. This means an IEEE 802.11b adapter can interface directly with an IEEE 802.11g access point (and vice versa) at 11 Mbps or lower depending on range. IEEE 802.11g has several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:Table 160   IEEE 802.11gDATA RATE (MBPS) MODULATION1 DBPSK (Differential Binary Phase Shift Keyed)2 DQPSK (Differential Quadrature Phase Shift Keying)5.5 / 11 CCK (Complementary Code Keying) 6/9/12/18/24/36/48/54 OFDM (Orthogonal Frequency Division Multiplexing)
P-660H/HW/W-T Series User’ Guide425 Appendix LIEEE 802.1xIn June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:• User based identification that allows for roaming.• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. • Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations.RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:• Authentication Determines the identity of the users.• AuthorizationDetermines the network services available to authenticated users once they are connected to the network.• AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless station and the network RADIUS server. Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:• Access-RequestSent by an access point requesting authentication.• Access-RejectSent by a RADIUS server rejecting access.• Access-AcceptSent by a RADIUS server allowing access.
P-660H/HW/W-T Series User’ GuideAppendix L 426• Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:• Accounting-RequestSent by the access point requesting accounting.• Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5,EAP-TLS,EAP-TTLS,PEAP and LEAP.The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information.EAP-MD5 (Message-Digest Algorithm 5)MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text. However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption.
P-660H/HW/W-T Series User’ Guide427 Appendix LEAP-TLS (Transport Layer Security)With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP)Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.LEAPLEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key ExchangeThe AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.Note: EAP-MD5 cannot be used with Dynamic WEP Key Exchange
P-660H/HW/W-T Series User’ GuideAppendix L 428For added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.WPAUser Authentication WPA applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless stations using an external RADIUS database. EncryptionWPA improves data encryption by using Temporal Key Integrity Protocol (TKIP) or Advanced Encryption Standard (AES), Message Integrity Check (MIC) and IEEE 802.1x.TKIP uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless stations. This all happens in the background automatically.AES (Advanced Encryption Standard) also uses a secret key. This implementation of AES applies a 128-bit key to 128-bit blocks of data.Table 161   Comparison of EAP Authentication TypesEAP-MD5 EAP-TLS EAP-TTLS PEAP LEAPMutual Authentication No Yes Yes Yes YesCertificate – Client No Ye s Optional Optional NoCertificate – Server No Yes Yes Yes NoDynamic Key Exchange No Yes Yes Yes Ye sCredential Integrity None Strong Strong Strong ModerateDeployment Difficulty Easy Hard Moderate Moderate ModerateClient Identity Protection No No Yes Ye s No
P-660H/HW/W-T Series User’ Guide429 Appendix LThe Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), TKIP makes it much more difficult to decrypt data on a Wi-Fi network than WEP, making it difficult for an intruder to break into the network. The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it’s still an improvement over WEP as it employs an easier-to-use, consistent, single, alphanumeric password.Security Parameters SummaryRefer to this table to see what other security parameters you should configure for each Authentication Method/ key management protocol type.
