P-320W v3 User’s Guide 21CHAPTER 1 Getting to Know Your P-320W v31.1 OverviewThis chapter introduces the main features and applications of the P-320W v3.The P-320W v3 extends the range of your existing wired network without additional wiring, providing easy network access to mobile users. It acts as a secure broadband router for all data passing between the Internet and your local network. You can set up a wireless network with other IEEE 802.11b/g compatible devices. The following figure shows computers in a WLAN connecting to the P-320W v3 (A), which has a DSL connection to the Internet. The P-320W v3 has a built-in firewall (B) to protect the network. It also has the Network Address Translation (NAT) feature enabled by default.Figure 1 Secure Wireless Internet Access in Router Mode The P-320W v3 can also serve as a wireless client enabling network devices to connect to an existing wired or wireless network. Features, such as firewall and NAT, are available. Networking devices cannot connect wirelessly to the P-320W v3 when it is acting as a wireless client.ABWLANInternetDSL
Chapter 1 Getting to Know Your P-320W v3P-320W v3 User’s Guide22In the following figure, the P-320W v3 (A) enables the wired computers to connect to the access point (B) and gain access to LAN/Internet.Figure 2 Using the P-320W v3 as a Wireless Client1.2 Ways to Manage the P-320W v3Use any of the following methods to manage the P-320W v3.•Web Configurator. This is recommended for everyday management of the P-320W v3 using a (supported) web browser. •SNMP. Simple Network Management Protocol is a communication protocol for collecting information from devices on the network.1.3 Good Habits for Managing the P-320W v3Do the following things regularly to make the P-320W v3 more secure and to manage the P-320W v3 more effectively.• Change the password. Use a password that’s not easy to guess and that consists of different types of characters, such as numbers and letters.• Write down the password and put it in a safe place.• Back up the configuration (and make sure you know how to restore it). Restoring an earlier working configuration may be useful if the device becomes unstable or even crashes. If you forget your password, you will have to reset the P-320W v3 to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the P-320W v3. You could simply restore your last configuration.ABInternetDSLFirewallISP

Chapter 3 Connection WizardP-320W v3 User’s Guide 45personal computer interacts with a broadband modem (for example DSL, cable, wireless, etc.) to achieve access to high-speed data networks.For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for instance, RADIUS). One of the benefits of PPPoE is the ability to let end users access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for specific users.Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it requires no specific configuration of the broadband modem at the subscriber’s site.By implementing PPPoE directly on the P-320W v3 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the P-320W v3 does that part of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.Refer to the appendix for more information on PPPoE.Figure 22 Wizard Step 3: PPPoE ConnectionThe following table describes the labels in this screen.Table 15 Wizard Step 3: PPPoE ConnectionLABEL DESCRIPTIONISP Parameter for Internet AccessConnection TypeSelect the PPP over Ethernet option for a dial-up connection.Service Name Type the name of your service provider.User Name Type the user name given to you by your ISP.

Chapter 3 Connection WizardP-320W v3 User’s Guide48The following table describes the labels in this screen3.4.5 WAN IP Address AssignmentEvery computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.You can obtain your IP address from the IANA, from an ISP or have it assigned by a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your 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.3.4.6 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 Table 17 Wizard Step 3: Your IP AddressLABEL DESCRIPTIONGet automatically from your ISP Select this option If your ISP did not assign you a fixed IP address. This is the default selection. If you choose this option, skip directly to section Section 3.4.9 on page 51.Use fixed IP address provided by your ISPSelect this option if you were given IP address and/or DNS server settings by the ISP. The fixed IP address should be in the same subnet as your broadband modem or router. Back Click Back to return to the previous screen.Next Click Next to continue. Exit Click Exit to close the wizard screen without saving.Table 18 Private IP Address Ranges10.0.0.0 -10.255.255.255172.16.0.0 -172.31.255.255192.168.0.0 -192.168.255.255
Chapter 3 Connection WizardP-320W v3 User’s Guide 49addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network.Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.1, for your P-320W v3, 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 P-320W v3 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 P-320W v3 unless you are instructed to do otherwise.3.4.7 DNS Server Address AssignmentUse DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa, for instance, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The P-320W v3 can get the DNS server addresses in the following ways.1The ISP tells you the DNS server addresses, usually in the form of an information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in the Wizard and/or WAN > Internet Connectionscreen.2If the ISP did not give you DNS server information, leave the DNS Server fields set to 0.0.0.0 in the Wizard screen and/or set to From ISP in the WAN >Internet Connection screen for the ISP to dynamically assign the DNS server IP addresses.
Chapter 3 Connection WizardP-320W v3 User’s Guide503.4.8 WAN IP and DNS Server Address AssignmentThe following wizard screen allows you to assign a fixed WAN IP address and DNS server addresses.

System DNS Server Address Assignment (if applicable)DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. The P-320W v3 uses a system DNS server (in the order you specify here) to resolve domain names for DDNS and the time server.First DNS ServerSecond DNS Server Third DNS Server Enter the DNS server's IP address in the fields provided.If you do not configure a system DNS server, you must use IP addresses when configuring DDNS and the time server.Back Click Back to return to the previous screen.Next Click Next to continue.

See the appendices for more detailed information about wireless networks.The following figure provides an example of a wireless network.Figure 29 Example of a Wireless NetworkThe wireless network is the part in the blue circle. In this wireless network, devices A and B are called wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the printer) or with the Internet. Your P-320W v3 is the AP.Every wireless network must follow these basic guidelines.• Every wireless client in the same wireless network must use the same SSID.The SSID is the name of the wireless network. It stands for Service Set IDentity.
Chapter 4 Wireless LANP-320W v3 User’s Guide56• If two wireless networks overlap, they should use different channels.Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information.• Every wireless client in the same wireless network must use security compatible with the AP.Security stops unauthorized devices from using the wireless network. It can also protect the information that is sent in the wireless network.4.2 What You Can Do•Use the General Wireless screen (Section 4.4 on page 60) configure your P-320W v3 as a wireless router or access point (AP).•Use the MAC Filter screen (Section 4.5 on page 68) to configure the P-320W v3 to give or deny access to up to 32 devices.•Use the WPS screen (Section 4.6 on page 69) to enable/disable WPS, view or generate a new PIN number and check current WPS status.•Use the WPS Station screen (Section 4.7 on page 70) to add a wireless station using WPS.•Use the Wireless LAN Advanced screen (Section 4.8 on page 70) to configure your P-320W v3’s advanced wireless setup.4.3 What You Need To KnowThe following sections provide information that can help you set up your wireless network. It also introduces different types of wireless security you can set up in the wireless network.4.3.1 SSIDNormally, the AP acts like a beacon and regularly broadcasts the SSID in the area. You can hide the SSID instead, in which case the AP does not broadcast the SSID. In addition, you should change the default SSID to something that is difficult to guess.This type of security is fairly weak, however, because there are ways for unauthorized devices to get the SSID. In addition, unauthorized devices can still see the information that is sent in the wireless network.
Chapter 4 Wireless LANP-320W v3 User’s Guide 574.3.2 MAC Address FilterEvery wireless client has a unique identification number, called a MAC address.1 A MAC address is usually written using twelve hexadecimal characters2; for example, 00A0C5000002 or 00:A0:C5:00:00:02. To get the MAC address for each wireless client, see the appropriate User’s Guide or other documentation.You can use the MAC address filter to tell the AP which wireless clients are allowed or not allowed to use the wireless network. If a wireless client is allowed to use the wireless network, it still has to have the correct settings (SSID, channel, and security). If a wireless client is not allowed to use the wireless network, it does not matter if it has the correct settings.This type of security does not protect the information that is sent in the wireless network. Furthermore, there are ways for unauthorized devices to get the MAC address of an authorized wireless client. Then, they can use that MAC address to use the wireless network.4.3.3 User AuthenticationYou can make every user log in to the wireless network before they can use it. This is called user authentication. However, every wireless client in the wireless network has to support IEEE 802.1x to do this.For wireless networks, there are two typical places to store the user names and passwords for each user.• In the AP: this feature is called a local user database or a local database.• In a RADIUS server: this is a server used in businesses more than in homes.If your AP does not provide a local user database and if you do not have a RADIUS server, you cannot set up user names and passwords for your users.Unauthorized devices can still see the information that is sent in the wireless network, even if they cannot use the wireless network. Furthermore, there are ways for unauthorized wireless users to get a valid user name and password. Then, they can use that user name and password to use the wireless network.Local user databases also have an additional limitation that is explained in the next section.1. Some wireless devices, such as scanners, can detect wireless networks but cannot use wireless networks. These kinds of wireless devices might not have MAC addresses.2. Hexadecimal characters are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
Chapter 4 Wireless LANP-320W v3 User’s Guide584.3.4 EncryptionWireless networks can use encryption to protect the information that is sent in the wireless network. Encryption is like a secret code. If you do not know the secret code, you cannot understand the message.The types of encryption you can choose depend on the type of user authentication. (See Section 4.3.3 on page 57 for information about this.)For example, if the wireless network has a RADIUS server, you can choose WPAor WPA2. If users do not log in to the wireless network, you can choose no encryption, Static WEP,WPA-PSK, or WPA2-PSK.Usually, you should set up the strongest encryption that every wireless client in the wireless network supports. For example, suppose the AP does not have a local user database, and you do not have a RADIUS server. Therefore, there is no user authentication. Suppose the wireless network has two wireless clients. Device A only supports WEP, and device B supports WEP and WPA. Therefore, you should set up Static WEP in the wireless network.Note: It is recommended that wireless networks use WPA-PSK,WPA, or stronger encryption. IEEE 802.1x and WEP encryption are better than none at all, but it is still possible for unauthorized devices to figure out the original information pretty quickly.Note: It is not possible to use WPA-PSK,WPA or stronger encryption with a local user database. In this case, it is better to set up stronger encryption with no authentication than to set up weaker encryption with the local user database.When you select WPA2 or WPA2-PSK in your P-320W v3, you can also select an option (WPA Compatible) to support WPA as well. In this case, if some wireless clients support WPA and some support WPA2, you should set up WPA2-PSK or WPA2 (depending on the type of wireless network login) and select the WPACompatible option in the P-320W v3.Many types of encryption use a key to protect the information in the wireless network. The longer the key, the stronger the encryption. Every wireless client in the wireless network must have the same key.

Chapter 4 Wireless LANP-320W v3 User’s Guide 594.3.4.1 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 consist of between 8 and 63 ASCII characters or 64 hexadecimal characters (including spaces and symbols).2The AP checks each wireless client's password and allows it to join the network only if the password matches.3The AP and wireless clients generate a common PMK (Pairwise Master Key). The key itself is not sent over the network, but is derived from the PSK and the SSID. 4The AP and wireless clients use the TKIP or AES encryption process, the PMK and information exchanged in a handshake to create temporal encryption keys. They use these keys to encrypt data exchanged between them.Figure 30 WPA-PSK Authentication4.3.4.2 WPA with RADIUS Application ExampleTo set up WPA, you need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.1The AP passes the wireless client's authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3A 256-bit Pairwise Master Key (PMK) is derived from the authentication process by the RADIUS server and the client.
Chapter 4 Wireless LANP-320W v3 User’s Guide604The RADIUS server distributes the PMK to the AP. The AP then sets up a key hierarchy and management system, using the PMK to dynamically generate unique data encryption keys. The keys are used to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.Figure 31 WPA with RADIUS Application Example4.3.5 WiFi Protected SetupWiFi Protected Setup (WPS) is an industry standard specification, defined by the WiFi Alliance. WPS allows you to quickly set up a wireless network with strong security, without having to configure security settings manually. Depending on the devices in your network, you can either press a button (on the device itself, or in its configuration utility) or enter a PIN (Personal Identification Number) in the devices. Then, they connect and set up a secure network by themselves. See how to set up a secure wireless network using WPS in the Section 6.2 on page 77.4.4 General Wireless LAN Screen Use this screen to configure your P-320W v3 as a wireless router or access point (AP).The P-320W v3 can broadcast up to four wireless profiles at the same time. This means that users can connect to the P-320W v3 using different SSIDs.You can only secure the connection on one SSID profile (AP1). Clients connecting to the P-320W v3 using different SSIDs are in the same subnet but cannot communicate with each other.

P-320W v3 User’s Guide 93CHAPTER 9 Network Address Translation(NAT)9.1 OverviewThis chapter discusses how to configure NAT on the P-320W v3.NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet. For example, the source address of an outgoing packet, used within one network is changed to a different IP address known within another network.9.2 What You Can Do•Use the General NAT screen (Section 9.4 on page 96) to enable NAT on your P-320W v3.•Use the Port Forwarding screen (Section 9.5 on page 97) to define the local servers to which the incoming services will be forwarded.•Use the Trigger Port screen (Section 9.3.2 on page 95) change your P-320W v3’s trigger port settings.9.3 What You Need to KnowThe following section provides information on how you can properly configure NAT.Note: You must create a firewall rule in addition to setting up NAT, to allow traffic from the WAN to be forwarded through the P-320W v3.9.3.1 Port Forwarding: Services and Port NumbersA port forwarding set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even
Chapter 9 Network Address Translation (NAT)P-320W v3 User’s Guide94though NAT makes your whole inside network appear as a single machine to the outside world. Use the Application screen to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers.In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.Note: Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP.9.3.1.1 Configuring Servers Behind Port Forwarding ExampleLet's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of 192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the InternetFigure 59 Multiple Servers Behind NAT Example9.3.2 Trigger Port Forwarding Some services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the InternetLAN WAN192.168.1.1192.168.1.36A=192.168.1.33B=192.168.1.34C=192.168.1.35
Chapter 9 Network Address Translation (NAT)P-320W v3 User’s Guide 95WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address. Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The P-320W v3 records the IP address of a LAN computer that sends traffic to the WAN to request a service with a specific port number and protocol (a "trigger" port). When the P-320W v3's WAN port receives a response with a specific port number and protocol ("incoming" port), the P-320W v3 forwards the traffic to the LAN IP address of the computer that sent the request. After that computer’s connection for that service closes, another computer on the LAN can use the service in the same manner. This way you do not need to configure a new IP address each time you want a different LAN computer to use the application.9.3.2.1 Trigger Port Forwarding Example The following is an example of trigger port forwarding.Figure 60 Trigger Port Forwarding Process: Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the P-320W v3 to record Jane’s computer IP address. The P-320W v3 associates Jane's computer IP address with the "incoming" port range of 6970-7170.3The Real Audio server responds using a port number ranging between 6970-7170.4The P-320W v3 forwards the traffic to Jane’s computer IP address. 5Only Jane can connect to the Real Audio server until the connection is closed or times out. The P-320W v3 times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). InternetJane’s computerReal Audio ServerPort 7070

P-320W v3 User’s Guide 101CHAPTER 10VLAN10.1 OverviewThis chapter shows you how to configure VLANs on your P-320W v3.A Virtual LAN (VLAN) allows a physical network to be partitioned into multiple logical networks. Only stations within the same group can communicate with each other. Stations on a logical network can belong to one or more groups.In the figure below, your P-320W v3 (C) has VLAN configured on two of its ports. Frames coming from computer A are tagged with Port VLAN ID (PVID) 1 and those from computer B are tagged with PVID 2. When computers A and B request IP addresses, the P-320W v3 forwards this to the VLAN-aware switch (D). The switch sends each request to the corresponding DHCP server. Computer A gets its IP address from DHCP Server 1, and computer B gets its IP address from DHCP server 2.Figure 66 VLAN Example10.2 What You Can DoUse the VLAN screen (Section 10.4 on page 102) to configure the Port VLAN ID (PVID) on the physical ports of the P-320W v3.

Chapter 10 VLANP-320W v3 User’s Guide10210.3 What You Need to KnowThe following sections provide information that can help you configure the VLAN screen of your P-320W v3.10.3.1 How VLAN WorksA tagged VLAN uses an explicit tag (VLAN ID) in the MAC header to identify the VLAN membership of a frame across bridges - they are not confined to the switch on which they were created. The VLANs can be created statically by hand or dynamically through GVRP (which is an 802.1 protocol). The VLAN ID associates a frame with a specific VLAN and provides the information that switches need to process the frame across the network. A tagged frame is four bytes longer than an untagged frame and contains two bytes for the TPID (Tag Protocol Identifier, residing within the type/length field of the Ethernet frame) and two bytes for the TCI (Tag Control Information, starting after the source address field of the Ethernet frame).10.3.2 VLAN Tag The CFI (Canonical Format Indicator) is a single-bit flag, always set to zero for Ethernet switches. If a frame received at an Ethernet port has a CFI set to 1, then that frame should not be forwarded as it is to an untagged port. The remaining twelve bits define the VLAN ID, giving a possible maximum number of 4,096 VLANs. Note that user priority and VLAN ID are independent of each other. A frame with VID (VLAN Identifier) of null (0) is called a priority frame, meaning that only the priority level is significant and the default VID of the ingress port is given as the VID of the frame. Of the 4096 possible VIDs, a VID of 0 is used to identify priority frames and the value 4095 (FFF) is reserved, so the maximum possible number of VLAN configurations is 4,094. 10.4 VLAN ScreenUse this screen to configure the Port VLAN ID (PVID) on the physical ports of the P-320W v3. The P-320W v3 forwards tagged frames to a VLAN-aware switch that can send the frames to its corresponding destination.Note: Tagged traffic remains in the same VLAN and cannot be seen by other VLANs.TPID 2 BytesUser Priority 3 BitsCFI1 BitVLAN ID12 bits

Chapter 11 WANP-320W v3 User’s Guide 10911.3.2 PPPoE EncapsulationThe P-320W v3 supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPP over Ethernet 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).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 P-320W v3 (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the P-320W v3 does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.Getautomatically from ISP Select this option If your ISP did not assign you a fixed IP address. This is the default selection.

P-320W v3 User’s Guide 117CHAPTER 12Firewall12.1 OverviewThis chapter gives some background information on firewalls and explains how to get started with the P-320W v3’s firewall.Originally, the term “firewall” referred to a construction technique designed to prevent the spread of fire from one room to another. The networking term "firewall" is a system or group of systems that enforces an access-control policy between two networks. It may also be defined as a mechanism used to protect a trusted network from a network that is not trusted. Of course, firewalls cannot solve every security problem. A firewall is one of the mechanisms used to establish a network security perimeter in support of a network security policy. It should never be the only mechanism or method employed. For a firewall to guard effectively, you must design and deploy it appropriately. This requires integrating the firewall into a broad information-security policy. In addition, specific policies must be implemented within the firewall itself. 12.2 What You Can Do•Use the General screen (Section 12.4 on page 119) to enable or disable the P-320W v3’s firewall.•Use the Services screen (Section 12.5 on page 119) to to enable service blocking, enter/delete/modify the services you want to block and the date/time you want to block them.12.3 What You Need to KnowThe following sections provide more information about the P-320W v3’s firewalls.
Chapter 12 FirewallP-320W v3 User’s Guide11812.3.1 About the P-320W v3 FirewallThe P-320W v3 firewall is a stateful inspection firewall and is designed to protect against Denial of Service attacks when activated (click the General tab underFirewall and then click the Enable Firewall check box). The P-320W v3's purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The P-320W v3 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 P-320W v3 is installed between the LAN and a broadband modem connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The P-320W v3 has one Ethernet WAN port and four Ethernet LAN ports, which are used to physically separate the network into two areas.The WAN (Wide Area Network) port attaches to the broadband (cable or DSL) modem to the Internet.The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, "inbound access" is not allowed (by default) unless the remote host is authorized to use a specific service.12.3.1.1 Stateful Inspection Firewall Stateful inspection firewalls restrict access by screening data packets against defined access rules. They make access control decisions based on IP address and protocol. They also "inspect" the session data to assure the integrity of the connection and to adapt to dynamic protocols. These firewalls generally provide the best speed and transparency; however, they may lack the granular application level access control or caching that some proxies support. Firewalls, of one type or another, have become an integral part of standard security solutions for enterprises.12.3.2 Security Parameter Index (SPI)An SPI is used to distinguish different SAs terminating at the same destination and using the same IPSec protocol. This data allows for the multiplexing of SAs to a single gateway. The SPI (Security Parameter Index) along with a destination IP address uniquely identify a particular Security Association (SA). The SPI is transmitted from the remote VPN gateway to the local VPN gateway. The local VPN gateway then uses the network, encryption and key values that the administrator associated with the SPI to establish the tunnel. Current ZyXEL implementation assumes identical outgoing and incoming SPIs.

Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network. 5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces. 6Protect against IP spoofing by making sure the firewall is active.

P-320W v3 User’s Guide 131CHAPTER 14Static Route14.1 OverviewThis chapter shows you how to configure static routes for your P-320W v3.The P-320W v3 usually uses the default gateway to route outbound traffic from computers on the LAN to the Internet. To have the P-320W v3 send data to devices not reachable through the default gateway, use static routes.For example, the next figure shows a computer (A) connected to the P-320W v3’s LAN interface. The P-320W v3 routes most traffic from Ato the Internet through the P-320W v3’s default gateway (R1). You create one static route to connect to services offered by your ISP behind router R2. You create another static route to communicate with a separate network behind a router R3 connected to the LAN. Figure 77 Example of Static Routing TopologyWANR1R2AR3LANInternet
Chapter 14 Static RouteP-320W v3 User’s Guide13214.2 What You Can DoUse the IP Static Route screen (Section 14.3 on page 132) to create and edit static routes on your P-320W v3.14.3 IP Static Route ScreenClick Management > Static Route to open the IP Static Route screen. The following screen displays.Figure 78 Management > Static Route > IP Static RouteThe following table describes the labels in this screen.Table 53 Management > Static Route > IP Static RouteLABEL DESCRIPTION#This is the index number of an individual static route. The first entry is for the default route and not editable.Active This icon is turned on when this static route is active.Click the Edit icon under Modify and select the Active checkbox in the Static Route Setup screen to enable the static route. Clear the checkbox to disable this static route without having to delete the entry.Destination This parameter specifies the IP network address of the final destination. Routing is always based on network number. Gateway This is the IP address of the gateway. The gateway is an immediate neighbor of your P-320W v3 that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your P-320W v3; over the WAN, the gateway must be the IP address of one of the remote nodes.Modify Click the Edit icon to open the static route setup screen. Modify a static route or create a new static route in the Static Route Setup screen.Click the Remove icon to delete a static route.

Leave this field blank to delete this static route.Active This field allows you to activate/deactivate this static route.Private This parameter determines if the P-320W v3 will include this route to a remote node in its RIP broadcasts.Select this check box to keep this route private and not included in RIP broadcasts. Clear this checkbox to propagate this route to other hosts through RIP broadcasts.Destination IP AddressThis 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 Enter the IP subnet mask here.Gateway IP AddressEnter the IP address of the gateway. The gateway is an immediate neighbor of your P-320W v3 that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your P-320W v3; over the WAN, the gateway must be the IP address of one of the Remote Nodes.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. Enter 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.

P-320W v3 User’s Guide 141CHAPTER 16Universal Plug-and-Play (UPnP)16.1 OverviewThis chapter introduces the UPnP feature in the web configurator.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 16.4 on page 143 for configuration instructions.16.2 What You Can DoUse the General screen (Section 16.4 on page 143) to activate UPnP.16.3 What You Need to KnowThe following sections provide information that can help you configure the UPnP screen. 16.3.1 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.
Chapter 16 Universal Plug-and-Play (UPnP)P-320W v3 User’s Guide14216.3.2 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.16.3.3 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. When a UPnP device joins a network, it announces its presence with a multicast message. For security reasons, the P-320W v3 allows multicast messages on the LAN only.All UPnP-enabled devices may communicate freely with each other without additional configuration. Disable UPnP if this is not your intention. 16.3.4 UPnP and ZyXELZyXEL has achieved UPnP certification from the Universal Plug and Play Forum UPnP™ Implementers Corp. (UIC). ZyXEL's UPnP implementation supports Internet Gateway Device (IGD) 1.0.See the following sections for examples of installing and using UPnP.

See the chapter about wizard setup for more information on the next few screens.17.2 What You Can Do•Use the General screen (Section 17.4 on page 158) to identify the P-320W v3 in an Ethernet network.•Use the Dynamic DNS screen (Section 17.5 on page 160) to change your P-320W v3’s DDNS settings•Use the Time Setting screen (Section 17.6 on page 161) to change your P-320W v3’s time and date.17.3 What You Need to KnowThe following sections provide information that can be helpful in configuring the screens in this chapter.17.3.1 Dynamic DNS Introduction Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in 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
Chapter 17 SystemP-320W v3 User’s Guide158server that would still like to have a domain name. The Dynamic DNS service provider will give you a password or key.17.3.2 DynDNS Wildcard Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.If you have a private WAN IP address, then you cannot use Dynamic DNS.17.4 System General Screen Use this screen to identify the P-320W v3 in an Ethernet network.Click Maintenance > System.

P-320W v3 User’s Guide 207APPENDIX B IP Addresses and SubnettingThis appendix introduces IP addresses and subnet masks. IP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.Introduction to IP AddressesOne part of the IP address is the network number, and the other part is the host ID. In the same way that houses on a street share a common street name, the hosts on a network share a common network number. Similarly, as each house has its own house number, each host on the network has its own unique identifying number - the host ID. Routers use the network number to send packets to the correct network, while the host ID determines to which host on the network the packets are delivered.StructureAn IP address is made up of four parts, written in dotted decimal notation (for example, 192.168.1.1). Each of these four parts is known as an octet. An octet is an eight-digit binary number (for example 11000000, which is 192 in decimal notation). Therefore, each octet has a possible range of 00000000 to 11111111 in binary, or 0 to 255 in decimal.
Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide208The following figure shows an example IP address in which the first three octets (192.168.1) are the network number, and the fourth octet (16) is the host ID.Figure 121 Network Number and Host IDHow much of the IP address is the network number and how much is the host ID varies according to the subnet mask. Subnet MasksA subnet mask is used to determine which bits are part of the network number, and which bits are part of the host ID (using a logical AND operation). The term “subnet” is short for “sub-network”.A subnet mask has 32 bits. If a bit in the subnet mask is a “1” then the corresponding bit in the IP address is part of the network number. If a bit in the subnet mask is “0” then the corresponding bit in the IP address is part of the host ID. The following example shows a subnet mask identifying the network number (in bold text) and host ID of an IP address (192.168.1.2 in decimal).Table 85 Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)IP Address (Binary) 11000000 10101000 00000001 00000010Subnet Mask (Binary) 11111111 11111111 11111111 00000000
Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide 209By convention, subnet masks always consist of a continuous sequence of ones beginning from the leftmost bit of the mask, followed by a continuous sequence of zeros, for a total number of 32 bits.Subnet masks can be referred to by the size of the network number part (the bits with a “1” value). For example, an “8-bit mask” means that the first 8 bits of the mask are ones and the remaining 24 bits are zeroes.Subnet masks are expressed in dotted decimal notation just like IP addresses. The following examples show the binary and decimal notation for 8-bit, 16-bit, 24-bit and 29-bit subnet masks. Network SizeThe size of the network number determines the maximum number of possible hosts you can have on your network. The larger the number of network number bits, the smaller the number of remaining host ID bits. An IP address with host IDs of all zeros is the IP address of the network (192.168.1.0 with a 24-bit subnet mask, for example). An IP address with host IDs of all ones is the broadcast address for that network (192.168.1.255 with a 24-bit subnet mask, for example).Network Number 11000000 10101000 00000001Host ID 00000010Table 86 Subnet MasksBINARYDECIMAL1STOCTET2NDOCTET3RDOCTET4THOCTET8-bit mask 11111111 00000000 00000000 00000000 255.0.0.016-bitmask11111111 11111111 00000000 00000000 255.255.0.024-bitmask11111111 11111111 11111111 00000000 255.255.255.029-bitmask11111111 11111111 11111111 11111000 255.255.255.248Table 85 Subnet Mask - Identifying Network Number1STOCTET:(192)2NDOCTET:(168)3RDOCTET:(1)4TH OCTET(2)
Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide210As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:NotationSince the mask is always a continuous number of ones beginning from the left, followed by a continuous number of zeros for the remainder of the 32 bit mask, you can simply specify the number of ones instead of writing the value of each octet. This is usually specified by writing a “/” followed by the number of bits in the mask after the address. For example, 192.1.1.0 /25 is equivalent to saying 192.1.1.0 with subnet mask 255.255.255.128. The following table shows some possible subnet masks using both notations.

Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide 211SubnettingYou can use subnetting to divide one network into multiple sub-networks. In the following example a network administrator creates two sub-networks to isolate a group of servers from the rest of the company network for security reasons.In this example, the company network address is 192.168.1.0. The first three octets of the address (192.168.1) are the network number, and the remaining octet is the host ID, allowing a maximum of 28 – 2 or 254 possible hosts.The following figure shows the company network before subnetting. Figure 122 Subnetting Example: Before SubnettingYou can “borrow” one of the host ID bits to divide the network 192.168.1.0 into two separate sub-networks. The subnet mask is now 25 bits (255.255.255.128 or /25).The “borrowed” host ID bit can have a value of either 0 or 1, allowing two subnets; 192.168.1.0 /25 and 192.168.1.128 /25.
Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide212The following figure shows the company network after subnetting. There are now two sub-networks, A and B.Figure 123 Subnetting Example: After SubnettingIn a 25-bit subnet the host ID has 7 bits, so each sub-network has a maximum of 27 – 2 or 126 possible hosts (a host ID of all zeroes is the subnet’s address itself, all ones is the subnet’s broadcast address).192.168.1.0 with mask 255.255.255.128 is subnet A itself, and 192.168.1.127 with mask 255.255.255.128 is its broadcast address. Therefore, the lowest IP address that can be assigned to an actual host for subnet A is 192.168.1.1 and the highest is 192.168.1.126. Similarly, the host ID range for subnet B is 192.168.1.129 to 192.168.1.254.Example: Four Subnets The previous example illustrated using a 25-bit subnet mask to divide a 24-bit address into two subnets. Similarly, to divide a 24-bit address into four subnets, you need to “borrow” two host ID bits to give four possible combinations (00, 01, 10 and 11). The subnet mask is 26 bits (11111111.11111111.11111111.11000000) or 255.255.255.192.
Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide 213Each subnet contains 6 host ID bits, giving 26 - 2 or 62 hosts for each subnet (a host ID of all zeroes is the subnet itself, all ones is the subnet’s broadcast address).

Appendix B IP Addresses and SubnettingP-320W v3 User’s Guide 215The following table is a summary for subnet planning on a network with a 16-bit network number. Configuring IP AddressesWhere you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask.If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. You must also enable Network Address Translation (NAT) on the P-320W v3. Once you have decided on the network number, pick an IP address for your P-320W v3 that is easy to remember (for instance, 192.168.1.1) but make sure that no other device on your network is using that IP address.The subnet mask specifies the network number portion of an IP address. Your P-320W v3 will compute the subnet mask automatically based on the IP address Table 95 16-bit Network Number Subnet PlanningNO. “BORROWED” HOST BITS SUBNET MASK NO. SUBNETS NO.

You don't need to change the subnet mask computed by the P-320W v3 unless you are instructed to do otherwise.Private IP AddressesEvery machine on the Internet must have a unique address. If your networks are isolated from the Internet (running only between two branch offices, for example) you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:• 10.0.0.0 — 10.255.255.255• 172.16.0.0 — 172.31.255.255• 192.168.0.0 — 192.168.255.255You can obtain your IP address from the IANA, from an ISP, or it can be assigned from a private network. If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you with the Internet addresses for your local networks. On the other hand, if you are part of a much larger organization, you should consult your network administrator for the appropriate IP addresses.Regardless of your particular situation, do not create an arbitrary IP address; always follow the guidelines above. 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.
P-320W v3 User’s Guide 217APPENDIX C Setting up Your Computer’s IPAddressAll computers must have a 10M or 100M Ethernet adapter card and TCP/IP installed. Windows 95/98/Me/NT/2000/XP, Macintosh OS 7 and later operating systems and all versions of UNIX/LINUX include the software components you need to install and use TCP/IP on your computer. Windows 3.1 requires the purchase of a third-party TCP/IP application package.TCP/IP should already be installed on computers using Windows NT/2000/XP, Macintosh OS 7 and later operating systems.After the appropriate TCP/IP components are installed, configure the TCP/IP settings in order to "communicate" with your network. If you manually assign IP information instead of using dynamic assignment, make sure that your computers have IP addresses that place them in the same subnet as the Prestige’s LAN port.

P-320W v3 User’s Guide 235APPENDIX D Wireless LANsWireless LAN TopologiesThis section discusses ad-hoc and infrastructure wireless LAN topologies.Ad-hoc Wireless LAN ConfigurationThe simplest WLAN configuration is an independent (Ad-hoc) WLAN that connects a set of computers with wireless stations (A, B, C). Any time two or more wireless adapters are within range of each other, they can set up an independent network, which is commonly referred to as an Ad-hoc network or Independent Basic Service Set (IBSS). The following diagram shows an example of notebook computers using wireless adapters to form an Ad-hoc wireless LAN. Figure 147 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
Appendix D Wireless LANsP-320W v3 User’s Guide236with each other. When Intra-BSS is disabled, wireless station A and B can still access the wired network but cannot communicate with each other.Figure 148 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.
Appendix D Wireless LANsP-320W v3 User’s Guide 237An ESSID (ESS IDentification) uniquely identifies each ESS. All access points and their associated wireless stations within the same ESS must have the same ESSID in order to communicate.Figure 149 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.Note: To comply with US FCC regulation, the country selection function has been completely removed from all US models. The above function is for non-US models only.
Appendix D Wireless LANsP-320W v3 User’s Guide238RTS/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. Figure 150 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.
Appendix D Wireless LANsP-320W v3 User’s Guide 239Note: 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.A large Fragmentation Threshold is recommended for networks not prone to interference while you should set a smaller threshold for busy networks or networks that are prone to interference.If the Fragmentation Threshold value is smaller than the RTS/CTS value (see previously) you set then the RTS (Request To Send)/CTS (Clear to Send) handshake will never occur as data frames will be fragmented before they reach RTS/CTS size.Preamble TypeA preamble is used to synchronize the transmission timing in your wireless network. There are two preamble modes: Long and Short.Short preamble takes less time to process and minimizes overhead, so it should be used in a good wireless network environment when all wireless stations support it. Select Long if you have a ‘noisy’ network or are unsure of what preamble mode your wireless stations support as all IEEE 802.11b compliant wireless adapters must support long preamble. However, not all wireless adapters support short preamble. Use long preamble if you are unsure what preamble mode the wireless adapters support, to ensure interpretability between the AP and the wireless stations and to provide more reliable communication in ‘noisy’ networks. Select Dynamic to have the AP automatically use short preamble when all wireless stations support it, otherwise the AP uses long preamble.Note: The AP and the wireless stations 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
Appendix D Wireless LANsP-320W v3 User’s Guide240several intermediate rate steps between the maximum and minimum data rates. The IEEE 802.11g data rate and modulation are as follows:IEEE 802.1xIn June 2001, the IEEE 802.1x standard was designed to extend the features of IEEE 802.11 to support extended authentication as well as providing additional accounting and control features. It is supported by Windows XP and a number of network devices. Some advantages of IEEE 802.1x are:• User based identification that allows for roaming.• Support for RADIUS (Remote Authentication Dial In User Service, RFC 2138, 2139) for centralized user profile and accounting management on a network RADIUS server. • Support for EAP (Extensible Authentication Protocol, RFC 2486) that allows additional authentication methods to be deployed with no changes to the access point or the wireless stations. RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The access point is the client and the server is the RADIUS server. The RADIUS server handles the following tasks:• Authentication Determines the identity of the users.• AuthorizationDetermines the network services available to authenticated users once they are connected to the network.•AccountingKeeps track of the client’s network activity. RADIUS is a simple package exchange in which your AP acts as a message relay between the wireless station and the network RADIUS server.

Appendix D Wireless LANsP-320W v3 User’s Guide 241Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the access point and the RADIUS server for user authentication:• Access-RequestSent by an access point requesting authentication.• Access-RejectSent by a RADIUS server rejecting access.• Access-AcceptSent by a RADIUS server allowing access. • Access-ChallengeSent by a RADIUS server requesting more information in order to allow access. The access point sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the access point and the RADIUS server for user accounting:•Accounting-RequestSent by the access point requesting accounting.• Accounting-ResponseSent by the RADIUS server to indicate that it has started or stopped accounting. In order to ensure network security, the access point and the RADIUS server use a shared secret key, which is a password, they both know. The key is not sent over the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. Types of Authentication This appendix discusses some popular authentication types: EAP-MD5,EAP-TLS,EAP-TTLS,PEAP and LEAP.The type of authentication you use depends on the RADIUS server or the AP. Consult your network administrator for more information.EAP-MD5 (Message-Digest Algorithm 5)MD5 authentication is the simplest one-way authentication method. The authentication server sends a challenge to the wireless station. The wireless station ‘proves’ that it knows the password by encrypting the password with the challenge and sends back the information. Password is not sent in plain text.
Appendix D Wireless LANsP-320W v3 User’s Guide242However, MD5 authentication has some weaknesses. Since the authentication server needs to get the plaintext passwords, the passwords must be stored. Thus someone other than the authentication server may access the password file. In addition, it is possible to impersonate an authentication server as MD5 authentication method does not perform mutual authentication. Finally, MD5 authentication method does not support data encryption with dynamic session key. You must configure WEP encryption keys for data encryption. EAP-TLS (Transport Layer Security)With EAP-TLS, digital certifications are needed by both the server and the wireless stations for mutual authentication. The server presents a certificate to the client. After validating the identity of the server, the client sends a different certificate to the server. The exchange of certificates is done in the open before a secured tunnel is created. This makes user identity vulnerable to passive attacks. A digital certificate is an electronic ID card that authenticates the sender’s identity. However, to implement EAP-TLS, you need a Certificate Authority (CA) to handle certificates, which imposes a management overhead. EAP-TTLS (Tunneled Transport Layer Service) EAP-TTLS is an extension of the EAP-TLS authentication that uses certificates for only the server-side authentications to establish a secure connection. Client authentication is then done by sending username and password through the secure connection, thus client identity is protected. For client authentication, EAP-TTLS supports EAP methods and legacy authentication methods such as PAP, CHAP, MS-CHAP and MS-CHAP v2. PEAP (Protected EAP)Like EAP-TTLS, server-side certificate authentication is used to establish a secure connection, then use simple username and password methods through the secured connection to authenticate the clients, thus hiding client identity. However, PEAP only supports EAP methods, such as EAP-MD5, EAP-MSCHAPv2 and EAP-GTC (EAP-Generic Token Card), for client authentication. EAP-GTC is implemented only by Cisco.LEAPLEAP (Lightweight Extensible Authentication Protocol) is a Cisco implementation of IEEE 802.1x. Dynamic WEP Key ExchangeThe AP maps a unique key that is generated with the RADIUS server. This key expires when the wireless connection times out, disconnects or reauthentication times out. A new WEP key is generated each time reauthentication is performed.
Appendix D Wireless LANsP-320W v3 User’s Guide 243If this feature is enabled, it is not necessary to configure a default encryption key in the Wireless screen. You may still configure and store keys here, but they will not be used while Dynamic WEP is enabled.Note: EAP-MD5 cannot be used with dynamic WEP key exchangeFor added security, certificate-based authentications (EAP-TLS, EAP-TTLS and PEAP) use dynamic keys for data encryption. They are often deployed in corporate environments, but for public deployment, a simple user name and password pair is more practical. The following table is a comparison of the features of authentication types.WPA(2)Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i standard. WPA2 (IEEE 802.11i) is a wireless security standard that defines stronger encryption, authentication and key management than WPA. Key differences between WPA(2) and WEP are improved data encryption and user authentication. EncryptionBoth WPA and WPA2 improve data encryption by using Temporal Key Integrity Protocol (TKIP), Message Integrity Check (MIC) and IEEE 802.1x. In addition to TKIP, WPA2 also uses Advanced Encryption Standard (AES) in the Counter mode with Cipher block chaining Message authentication code Protocol (CCMP) to offer stronger encryption. Temporal Key Integrity Protocol (TKIP) uses 128-bit keys that are dynamically generated and distributed by the authentication server. It includes a per-packet key mixing function, a Message Integrity Check (MIC) named Michael, an extended initialization vector (IV) with sequencing rules, and a re-keying mechanism.Table 97 Comparison of EAP Authentication TypesEAP-MD5 EAP-TLS EAP-TTLS PEAP LEAPMutual Authentication No Yes Yes Yes YesCertificate – Client No Yes Optional Optional NoCertificate – Server No Yes Yes Yes NoDynamic Key Exchange No Yes Yes Yes YesCredential Integrity None Strong Strong Strong ModerateDeployment Difficulty Easy Hard Moderate Moderate ModerateClient Identity ProtectionNo No Yes Yes No
Appendix D Wireless LANsP-320W v3 User’s Guide244TKIP regularly changes and rotates the encryption keys so that the same encryption key is never used twice. The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients. This all happens in the background automatically.WPA2 AES (Advanced Encryption Standard) is a block cipher that uses a 256-bit mathematical algorithm called Rijndael.The Message Integrity Check (MIC) is designed to prevent an attacker from capturing data packets, altering them and resending them. The MIC provides a strong mathematical function in which the receiver and the transmitter each compute and then compare the MIC. If they do not match, it is assumed that the data has been tampered with and the packet is dropped. By generating unique data encryption keys for every data packet and by creating an integrity checking mechanism (MIC), TKIP makes it much more difficult to decode data on a Wi-Fi network than WEP, making it difficult for an intruder to break into the network. The encryption mechanisms used for WPA and WPA-PSK are the same. The only difference between the two is that WPA-PSK uses a simple common password, instead of user-specific credentials. The common-password approach makes WPA-PSK susceptible to brute-force password-guessing attacks but it's still an improvement over WEP as it employs an easier-to-use, consistent, single, alphanumeric password. User AuthenticationWPA or WPA2 applies IEEE 802.1x and Extensible Authentication Protocol (EAP) to authenticate wireless clients using an external RADIUS database. If both an AP and the wireless clients support WPA2 and you have an external RADIUS server, use WPA2 for stronger data encryption. If you don't have an external RADIUS server, you should use WPA2 -PSK (WPA2 -Pre-Shared Key) that only requires a single (identical) password entered into each access point, wireless gateway and wireless client. As long as the passwords match, a wireless client will be granted access to a WLAN. If the AP or the wireless clients do not support WPA2, just use WPA or WPA-PSK depending on whether you have an external RADIUS server or not.Select WEP only when the AP and/or wireless clients do not support WPA or WPA2. WEP is less secure than WPA or WPA2.
Appendix D Wireless LANsP-320W v3 User’s Guide 24521.0.2 WPA(2)-PSK Application ExampleA WPA(2)-PSK application looks as follows.1First enter identical passwords into the AP and all wireless clients. The Pre-Shared Key (PSK) must consist of between 8 and 63 ASCII characters (including spaces and symbols).2The AP checks each wireless client's password and (only) allows it to join the network if the password matches.3The AP derives and distributes keys to the wireless clients.4The AP and wireless clients use the TKIP or AES encryption process to encrypt data exchanged between them.Figure 151 WPA(2)-PSK Authentication21.0.3 WPA(2) with RADIUS Application ExampleYou need the IP address of the RADIUS server, its port number (default is 1812), and the RADIUS shared secret. A WPA(2) application example with an external RADIUS server looks as follows. "A" is the RADIUS server. "DS" is the distribution system.1The AP passes the wireless client's authentication request to the RADIUS server.2The RADIUS server then checks the user's identification against its database and grants or denies network access accordingly.3The RADIUS server distributes a Pairwise Master Key (PMK) key to the AP that then sets up a key hierarchy and management system, using the pair-wise key to dynamically generate unique data encryption keys to encrypt every data packet that is wirelessly communicated between the AP and the wireless clients.
