BM2022w User’s Guide 17CHAPTER   1Getting Started1.1  About Your BM2022w The BM2022w has a built-in switch and two phone ports. It allows you to access the Internet by connecting to a WiMAX wireless network. You can use a traditional analog telephone to make Internet calls using the BM2022w’s Voice over IP (VoIP) communication capabilities. Additionally, The web browser-based Graphical User Interface (GUI), also known as the web configurator, provides easy management of the device and its features.See Chapter 14 on page 209 for a complete list of features for your model.1.1.1  WiMAX Internet AccessConnect your computer or network to the BM2022w for WiMAX Internet access. See the Quick Start Guide for instructions on hardware connection.In a wireless metropolitan area network (MAN), the BM2022w connects to a WiMAX base station (BS) for Internet access. The following diagram shows a notebook computer equipped with the BM2022w connecting to the Internet through a WiMAX base station (marked BS).Figure 1   Mobile Station and Base StationWhen the firewall is on, all incoming traffic from the Internet to your network is blocked unless it is initiated from your network. Use content filtering to block access to web sites with URLs containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude particular computers on your network from content filtering. For example, you could block access to certain web sites for the kids.
Chapter 1 Getting StartedBM2022w User’s Guide181.1.2  Make Calls via Internet Telephony Service ProviderIn a home or small office environment, you can use the BM2022w to make and receive the following types of VoIP telephone calls:• Peer-to-Peer calls - Use the BM2022w to make a call directly to the recipient’s IP address without using a SIP proxy server.Figure 2   VoIP Features - Peer-to-Peer Calls• Calls via a VoIP service provider - The BM2022w sends your call to a VoIP service provider’s SIP server which forwards your calls to either VoIP or PSTN phones.Figure 3    Calls via VoIP Service Provider1.2  BM2022w HardwareFollow the instructions in the Quick Start Guide to make hardware connections.

Chapter 1 Getting StartedBM2022w User’s Guide201.3  Good Habits for Managing the BM2022wDo the following things regularly to make the BM2022w more secure and to manage the BM2022w 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 BM2022w becomes unstable or even crashes. If you forget your password, you will have to reset the BM2022w to its factory default settings. If you backed up an earlier configuration file, you would not have to totally re-configure the BM2022w. You could simply restore your last configuration.Voice 1 & 2 Off No SIP account is registered, or the BM2022w is not receiving power.Green A SIP account is registered.Green (Blinking) A SIP account is registered, and the phone attached to the VoIP port is in use (off the hook).Yellow A SIP account is registered and has a voice message on the SIP server.Yellow (Blinking) A SIP account is registered and has a voice message on the SIP server, and the phone attached to the VoIP port is in use (off the hook).WLAN Off The Wi-Fi network is not operational.Green The Wi-Fi network is operational.Blinking Green The WiMAX Device is sending and receiving data across the Wi-Fi network.Table 2   The BM2022w LEDs behaviorLED STATE DESCRIPTION

You can then log into the BM2022w and manage it.4.9  Configuring Static Route for Routing to Another NetworkIn order to extend your Intranet and control traffic flowing directions, you may connect a router to the BM2022w’s LAN. The router may be used to separate two department networks. This tutorial shows how to configure a static routing rule for two network routings.In the following figure, router R is connected to the BM2022w’s LAN. R connects to two networks, N1 (192.168.1.x/24) and N2 (192.168.10.x/24). If you want to send traffic from computer A (in
Chapter 4 TutorialsBM2022w User’s Guide50N1 network) to computer B (in N2 network), the traffic is sent to the BM2022w’s WAN default gateway by default. In this case, computer B will never receive the traffic.You need to specify a static routing rule on the BM2022w to specify R as the router in charge of forwarding traffic to N2. In this case, the BM2022w routes traffic from computer A to R and then Rroutes the traffic to computer B.This tutorial uses the following example IP settings:Table 11   IP Settings in this TutorialDEVICE / COMPUTER IP ADDRESSThe BM2022w’s WAN 172.16.1.1The BM2022w’s LAN 192.168.1.1A192.168.1.34R’s IP address on N1  192.168.1.253N2BARN1N2BN1AR

BM2022w User’s Guide 69CHAPTER   6WiMAX6.1  OverviewThis chapter shows you how to set up and manage the connection between the BM2022w and your ISP’s base stations.6.1.1  What You Need to KnowThe following terms and concepts may help as you read through this chapter.WiMAX WiMAX (Worldwide Interoperability for Microwave Access) is the IEEE 802.16 wireless networking standard, which provides high-bandwidth, wide-range wireless service across wireless Metropolitan Area Networks (MANs). Huawei is a member of the WiMAX Forum, the industry group dedicated to promoting and certifying interoperability of wireless broadband products.In a wireless MAN, a wireless-equipped computer is known either as a mobile station (MS) or a subscriber station (SS). Mobile stations use the IEEE 802.16e standard and are able to maintain connectivity while switching their connection from one base station to another base station (handover) while subscriber stations use other standards that do not have this capability (IEEE 802.16-2004, for example). The following figure shows an MS-equipped notebook computer MS1moving from base station BS1’s coverage area and connecting to BS2.Figure 23   WiMAX: Mobile Station
Chapter 6 WiMAXBM2022w User’s Guide70WiMAX technology uses radio signals (around 2 to 10 GHz) to connect subscriber stations and mobile stations to local base stations. Numerous subscriber stations and mobile stations connect to the network through a single base station (BS), as in the following figure. Figure 24   WiMAX: Multiple Mobile StationsA base station’s coverage area can extend over many hundreds of meters, even under poor conditions. A base station provides network access to subscriber stations and mobile stations, and communicates with other base stations.The radio frequency and bandwidth of the link between the BM2022w and the base station are controlled by the base station. The BM2022w follows the base station’s configuration. AuthenticationWhen authenticating a user, the base station uses a third-party RADIUS or Diameter server known as an AAA (Authentication, Authorization and Accounting) server to authenticate the mobile or subscriber stations. The following figure shows a base station using an AAA server to authenticate mobile station MS,allowing it to access the Internet.Figure 25   Using an AAA ServerIn this figure, the dashed arrow shows the PKM (Privacy Key Management) secured connection between the mobile station and the base station, and the solid arrow shows the EAP secured connection between the mobile station, the base station and the AAA server. See the WiMAX security appendix for more details.
 Chapter 6 WiMAXBM2022w User’s Guide 71Frequency RangesThe following figure shows the BM2022w searching a range of frequencies to find a connection to a base station. Figure 26   Frequency RangesIn this figure, A is the WiMAX frequency range. “WiMAX frequency range” refers to the entire range of frequencies the BM2022w is capable of using to transmit and receive (see the Product Specifications appendix for details). In the figure, B shows the operator frequency range. This is the range of frequencies within the WiMAX frequency range supported by your operator (service provider).The operator range is subdivided into bandwidth steps. In the figure, each C is a bandwidth step.The arrow D shows the BM2022w searching for a connection.Have the BM2022w search only certain frequencies by configuring the downlink frequencies. Your operator can give you information on the supported frequencies. The downlink frequencies are points of the frequency range your BM2022w searches for an available connection. Use the Site Survey screen to set these bands. You can set the downlink frequencies anywhere within the WiMAX frequency range. In this example, the downlink frequencies have been set to search all of the operator range for a connection.Certification AuthorityA Certification Authority (CA) issues certificates and guarantees the identity of each certificate owner. There are commercial certification authorities like CyberTrust or VeriSign and government certification authorities. You can use the BM2022w to generate certification requests that contain identifying information and public keys and then send the certification requests to a certification authority.Certificate File FormatsThe certification authority certificate that you want to import has to be in one of these file formats:• Binary X.509: This is an ITU-T recommendation that defines the formats for X.509 certificates.• PEM (Base-64) encoded X.509: This Privacy Enhanced Mail format uses lowercase letters, uppercase letters and numerals to convert a binary X.509 certificate into a printable form.• Binary PKCS#7: This is a standard that defines the general syntax for data (including digital signatures) that may be encrypted. The BM2022w currently allows the importation of a PKS#7 file that contains a single certificate.
Chapter 6 WiMAXBM2022w User’s Guide72• PEM (Base-64) encoded PKCS#7: This Privacy Enhanced Mail (PEM) format uses 64 ASCII characters to convert a binary PKCS#7 certificate into a printable form.CINRCarrier to Interference-plus-Noise Ratio (CINR) measures the effectiveness of a wireless signal and plays an important role in allowing the BM2022w to decode signal burst. If a burst has a high signal strength and a high interference-plus-noise ratio, it can use Digital Signal Processing (DSP) to decode it; if the signal strength is lower, it can switch to an alternate burst profile.RSSIReceived Signal Strength Indicator (RSSI) measures the relative strength of a given wireless signal. This is important in determining if a signal is below the Clear-To-Send (CTS) threshold. If it is below the arbitrarily specified threshold, then BM2022w is free to transmit any data packets.EAP Authentication EAP (Extensible Authentication Protocol) is an authentication protocol that runs on top of the IEEE 802.1x transport mechanism in order to support multiple types of user authentication. By using EAP to interact with an EAP-compatible RADIUS server, an access point helps a wireless station and a RADIUS server perform authentication. The BM2022w supports EAP-TLS and EAP-TTLS (at the time of writing, TTLS is not available in Windows Vista). For EAP-TLS authentication type, you must first have a wired connection to the network and obtain the certificate(s) from a certificate authority (CA). Certificates (also called digital IDs) can be used to authenticate users and a CA issues certificates and guarantees the identity of each certificate owner.6.2  Connection SettingsThis screen allows you to configure how the BM2022w connects to the base stations on the WiMAX network.

CCM combines counter-mode encryption with CBC-MAC authentication.AES-CBC Select this to enable AES-CBC encryption. CBC creates message authentication code from a block cipher.Key EncryptionAES-key wrap Select this encapsulate cryptographic keys in a symmetric encryption algorithm.AES-ECB Select this to divide cryptographic keys into blocks and encrypt them separately.EAP SupplicantEAP Mode Select an Extensible Authentication Protocol (EAP) mode.The BM2022w supports the following:•EAP-TLS - In this protocol, digital certifications are needed by both the server and the wireless clients 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 - This protocol 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.

Through the NAP’s base station, which is identified by a NAP-ID, the subscriber’s BM2022w can access the Internet through a network service provider (NSP).  Access can be through another network service provider (Visited-Network Service Provider or V-NSP) or his own network service provider (Home NSP), depending on his service agreement.In the following scenario, the subscriber’s BM2022w cannot reach a base station owned by his Home NSP (base station with NAP-ID = 1).  The BM2022w uses ND&S and is able to access another base station with NAP-ID = 2.  This base station is associated with another service provider (V-NSP with NSP-ID = 20).  The subscriber’s service agreement specifies to route traffic from the other service provider to the Home NSP, so the Home NSP authenticates and authorizes the connection.Figure 31   ND&S ScenarioThe channel plan settings specify the allowed frequency range to search for a NAP.

Chapter 6 WiMAXBM2022w User’s Guide94
BM2022w User’s Guide 95CHAPTER   7Network Setting7.1  OverviewThis chapter shows you how to configure the BM2022w’s network setting.7.1.1  What You Need to KnowThe following terms and concepts may help as you read through this chapter.IP AddressIP addresses identify individual devices on a network. Every networking device (including computers, servers, routers, printers, etc.) needs an IP address to communicate across the network. These networking devices are also known as hosts.Subnet MasksSubnet masks determine the maximum number of possible hosts on a network. You can also use subnet masks to divide one network into multiple sub-networks.DHCPA DHCP (Dynamic Host Configuration Protocol) server can assign your BM2022w an IP address, subnet mask, DNS and other routing information when it’s turned on.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 Server fields; otherwise, leave them blank.Some ISPs choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The BM2022w supports the IPCP DNS server extensions through the DNS proxy feature.
Chapter 7 Network SettingBM2022w User’s Guide96If the Primary and Secondary DNS Server fields are not specified, for instance, left as 0.0.0.0, the BM2022w tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the BM2022w, the BM2022w 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. This way, the BM2022w can pass the DNS servers to the computers and the computers can query the DNS server directly without the BM2022w’s intervention.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:•RX/TX - the BM2022w will broadcast its routing table periodically and incorporate the RIP information that it receives.•RX Only - the BM2022w will not send any RIP packets but will accept all RIP packets received.•TX Only - the BM2022w will send out RIP packets but will not accept any RIP packets received.•None - the BM2022w 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 BM2022w 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-2Buses subnet broadcasting while RIP-2M uses multicasting.Port Forwarding A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make accessible to the outside world even though NAT makes your whole inside network appear as a single machine to the outside world.With port forwarding, you can forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded.For example, let's say you want to assign ports 21-25 to one FTP, Telnet and SMTP server (A in the example), port 80 to another (B in the example) and assign a default server IP address of
 Chapter 7 Network SettingBM2022w User’s Guide 97192.168.1.35 to a third (C in the example). You assign the LAN IP addresses and the ISP assigns the WAN IP address. The NAT network appears as a single host on the Internet.Figure 44   Multiple Servers Behind NAT ExampleTrigger PortsSome services use a dedicated range of ports on the client side and a dedicated range of ports on the server side. With regular port forwarding you set a forwarding port in NAT to forward a service (coming in from the server on the WAN) to the IP address of a computer on the client side (LAN). The problem is that port forwarding only forwards a service to a single LAN IP address. In order to use the same service on a different LAN computer, you have to manually replace the LAN computer's IP address in the forwarding port with another LAN computer's IP address, Trigger port forwarding solves this problem by allowing computers on the LAN to dynamically take turns using the service. The BM2022w 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 BM2022w's WAN port receives a response with a specific port number and protocol ("incoming" port), the BM2022w 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.ALGSome applications, such as SIP, cannot operate through NAT (are NAT un-friendly) because they embed IP addresses and port numbers in their packets’ data payload. Some NAT routers may include a SIP Application Layer Gateway (ALG). An Application Layer Gateway (ALG) manages a specific protocol (such as SIP, H.323 or FTP) at the application layer. A SIP ALG allows SIP calls to pass through NAT by examining and translating IP addresses embedded in the data stream.UPnPUniversal 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.How do I know if I'm using UPnP?
Chapter 7 Network SettingBM2022w User’s Guide98UPnP hardware is identified as an icon in the Network Connections folder (Windows XP). Each UPnP compatible device installed on your network will appear as a separate icon. Selecting the icon of a UPnP device will allow you to access the information and properties of that device. NAT TraversalUPnP NAT traversal automates the process of allowing an application to operate through NAT. UPnP network devices can automatically configure network addressing, announce their presence in the network to other UPnP devices and enable exchange of simple product and service descriptions. NAT traversal allows the following:• Dynamic port mapping• Learning public IP addresses• Assigning lease times to mappingsWindows Messenger is an example of an application that supports NAT traversal and UPnP. 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. UPnP and HuaweiHuawei has received UPnP certification from the official UPnP Forum (http://www.upnp.org). Huawei's UPnP implementation supports IGD 1.0 (Internet Gateway Device).The BM2022w only sends UPnP multicasts to the LAN.Content FilterInternet content filtering allows you to create and enforce Internet access policies tailored to their needs. Content filtering is the ability to block certain specific URL keywords.7.2  WANUse these settings to configure the WAN connection between the WiMAX Device and the service provider.

 Chapter 7 Network SettingBM2022w User’s Guide 1157.15.2  Trigger Port Forwarding ExampleThe following is an example of trigger port forwarding. In this example, J is Jane’s computer and Sis the Real Audio server.Figure 61   Trigger Port Forwarding Example1Jane requests a file from the Real Audio server (port 7070).2Port 7070 is a “trigger” port and causes the BM2022w to record Jane’s computer IP address. The BM2022w 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 BM2022w 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 BM2022w times out in three minutes with UDP (User Datagram Protocol), or two hours with TCP/IP (Transfer Control Protocol/Internet Protocol). Two points to remember about trigger ports:1Trigger events only happen on data that is coming from inside the BM2022w and going to the outside.2If an application needs a continuous data stream, that port (range) will be tied up so that another computer on the LAN can’t trigger it. 7.16  DMZUse this page to set the IP address of your network DMZ (if you have one) for the WiMAX Device.

BM2022w User’s Guide 129CHAPTER   8Security8.1  OverviewThis chapter shows you how to configure the BM2022w’s network settings.8.1.1  What You Need to KnowThe following terms and concepts may help as you read through this chapter.About the BM2022w’s Security FeaturesThe BM2022w security features are designed to protect against Denial of Service attacks when activated as well as block access to and from specific URLs and MAC addresses. Its purpose is to allow a private Local Area Network (LAN) to be securely connected to the Internet. The BM2022w can be used to prevent theft, destruction and modification of data. The BM2022w is installed between the LAN and a WiMAX base station connecting to the Internet. This allows it to act as a secure gateway for all data passing between the Internet and the LAN.The BM2022w has one Ethernet (LAN) port. The LAN (Local Area Network) port attaches to a network of computers, which needs security from the outside world. These computers will have access to Internet services such as e-mail, FTP and the World Wide Web. However, “inbound access” is not allowed (by default) unless the remote host is authorized to use a specific service.8.2  IP FilterUse this screen to block incoming connections from specific IP addresses.Click Security > Firewall > IP Filter to open this screen as shown next.Figure 70   IP Filter Screen

 Chapter 8 SecurityBM2022w User’s Guide 1498.12.1  IPSec ArchitectureThe overall IPSec architecture is shown as follows.Figure 82   IPSec ArchitectureIPSec AlgorithmsThe ESP (Encapsulating Security Payload) Protocol (RFC 2406) and AH (Authentication Header) protocol (RFC 2402) describe the packet formats and the default standards for packet structure (including implementation algorithms).The Encryption Algorithm describes the use of encryption techniques such as DES (Data Encryption Standard) and Triple DES algorithms.The Authentication Algorithms, HMAC-MD5 (RFC 2403) and HMAC-SHA-1 (RFC 2404, provide an authentication mechanism for the AH and ESP protocols. Key ManagementKey management allows you to determine whether to use IKE (ISAKMP) or manual key configuration in order to set up a VPN.
Chapter 8 SecurityBM2022w User’s Guide1508.12.2  EncapsulationThe two modes of operation for IPSec VPNs are Transport mode and Tunnel mode. At the time of writing, the BM2022w supports Tunnel mode only.Figure 83   Transport and Tunnel Mode IPSec EncapsulationTransport ModeTransport mode is used to protect upper layer protocols and only affects the data in the IP packet. In Transport mode, the IP packet contains the security protocol (AH or ESP) located after the original IP header and options, but before any upper layer protocols contained in the packet (such as TCP and UDP). With ESP, protection is applied only to the upper layer protocols contained in the packet. The IP header information and options are not used in the authentication process. Therefore, the originating IP address cannot be verified for integrity against the data. With the use of AH as the security protocol, protection is extended forward into the IP header to verify the integrity of the entire packet by use of portions of the original IP header in the hashing process.Tunnel Mode Tunnel mode encapsulates the entire IP packet to transmit it securely. A Tunnel mode is required for gateway services to provide access to internal systems. Tunnel mode is fundamentally an IP tunnel with authentication and encryption. This is the most common mode of operation. Tunnelmode is required for gateway to gateway and host to gateway communications. Tunnel mode communications have two sets of IP headers:•Outside header: The outside IP header contains the destination IP address of the VPN gateway.•Inside header: The inside IP header contains the destination IP address of the final system behind the VPN gateway. The security protocol appears after the outer IP header and before the inside IP header.
 Chapter 8 SecurityBM2022w User’s Guide 1518.12.3   IKE PhasesThere are two phases to every IKE (Internet Key Exchange) negotiation – phase 1 (Authentication) and phase 2 (Key Exchange). A phase 1 exchange establishes an IKE SA and the second one uses that SA to negotiate SAs for IPSec.Figure 84   Two Phases to Set Up the IPSec SAIn phase 1 you must:• Choose a negotiation mode.• Authenticate the connection by entering a pre-shared key.• Choose an encryption algorithm.• Choose an authentication algorithm.• Choose a Diffie-Hellman public-key cryptography key group (DH1 or DH2).• Set the IKE SA lifetime. This field allows you to determine how long an IKE SA should stay up before it times out. An IKE SA times out when the IKE SA lifetime period expires. If an IKE SA times out when an IPSec SA is already established, the IPSec SA stays connected.In phase 2 you must:• Choose an encryption algorithm.• Choose an authentication algorithm• Choose a Diffie-Hellman public-key cryptography key group.• Set the IPSec SA lifetime. This field allows you to determine how long the IPSec SA should stay up before it times out. The BM2022w automatically renegotiates the IPSec SA if there is traffic when the IPSec SA lifetime period expires. If an IPSec SA times out, then the IPSec router must renegotiate the SA the next time someone attempts to send traffic.8.12.4  Negotiation ModeThe phase 1 Negotiation Mode you select determines how the Security Association (SA) will be established for each connection through IKE negotiations.
Chapter 8 SecurityBM2022w User’s Guide152•Main Mode ensures the highest level of security when the communicating parties are negotiating authentication (phase 1). It uses 6 messages in three round trips: SA negotiation, Diffie-Hellman exchange and an exchange of nonces (a nonce is a random number). This mode features identity protection (your identity is not revealed in the negotiation). •Aggressive Mode is quicker than Main Mode because it eliminates several steps when the communicating parties are negotiating authentication (phase 1). However the trade-off is that faster speed limits its negotiating power and it also does not provide identity protection. It is useful in remote access situations where the address of the initiator is not know by the responder and both parties want to use pre-shared key authentication.8.12.5  IPSec and NATRead this section if you are running IPSec on a host computer behind the BM2022w.NAT is incompatible with the AH protocol in both Transport and Tunnel mode. An IPSec VPN using the AH protocol digitally signs the outbound packet, both data payload and headers, with a hash value appended to the packet. When using AH protocol, packet contents (the data payload) are not encrypted.A NAT device in between the IPSec endpoints will rewrite either the source or destination address with one of its own choosing. The VPN device at the receiving end will verify the integrity of the incoming packet by computing its own hash value, and complain that the hash value appended to the received packet doesn't match. The VPN device at the receiving end doesn't know about the NAT in the middle, so it assumes that the data has been maliciously altered.IPSec using ESP in Tunnel mode encapsulates the entire original packet (including headers) in a new IP packet. The new IP packet's source address is the outbound address of the sending VPN gateway, and its destination address is the inbound address of the VPN device at the receiving end. When using ESP protocol with authentication, the packet contents (in this case, the entire original packet) are encrypted. The encrypted contents, but not the new headers, are signed with a hash value appended to the packet.Tunnel mode ESP with authentication is compatible with NAT because integrity checks are performed over the combination of the "original header plus original payload," which is unchanged by a NAT device. Transport mode ESP with authentication is not compatible with NAT.8.12.6  VPN, NAT, and NAT TraversalNAT is incompatible with the AH protocol in both transport and tunnel mode. An IPSec VPN using the AH protocol digitally signs the outbound packet, both data payload and headers, with a hash value appended to the packet, but a NAT device between the IPSec endpoints rewrites the source or destination address. As a result, the VPN device at the receiving end finds a mismatch between the hash value and the data and assumes that the data has been maliciously altered.Table 63   VPN and NATSECURITY PROTOCOL MODE NATAH Transport NAH Tunnel NESP Tra nsport NESP Tunnel Y
 Chapter 8 SecurityBM2022w User’s Guide 153NAT is not normally compatible with ESP in transport mode either, but the BM2022w’s NATTraversal feature provides a way to handle this. NAT traversal allows you to set up an IKE SA when there are NAT routers between the two IPSec routers.Figure 85   NAT Router Between IPSec RoutersNormally you cannot set up an IKE SA with a NAT router between the two IPSec routers because the NAT router changes the header of the IPSec packet. NAT traversal solves the problem by adding a UDP port 500 header to the IPSec packet. The NAT router forwards the IPSec packet with the UDP port 500 header unchanged. In the above figure, when IPSec router A tries to establish an IKE SA, IPSec router B checks the UDP port 500 header, and IPSec routers A and B build the IKE SA.For NAT traversal to work, you must:• Use ESP security protocol (in either transport or tunnel mode).•Use IKE keying mode.• Enable NAT traversal on both IPSec endpoints.• Set the NAT router to forward UDP port 500 to IPSec router A.Finally, NAT is compatible with ESP in tunnel mode because integrity checks are performed over the combination of the "original header plus original payload," which is unchanged by a NAT device. The compatibility of AH and ESP with NAT in tunnel and transport modes is summarized in the following table.Y* - This is supported in the BM2022w if you enable NAT traversal.8.12.7  ID Type and ContentWith aggressive negotiation mode (see Section 8.12.4 on page 151), the BM2022w identifies incoming SAs by ID type and content since this identifying information is not encrypted. This enables the BM2022w to distinguish between multiple rules for SAs that connect from remote IPSec routers that have dynamic WAN IP addresses.Regardless of the ID type and content configuration, the BM2022w does not allow you to save multiple active rules with overlapping local and remote IP addresses.With main mode (see Section 8.12.4 on page 151), the ID type and content are encrypted to provide identity protection. In this case the BM2022w can only distinguish between up to 12 different incoming SAs that connect from remote IPSec routers that have dynamic WAN IP Table 64   VPN and NATSECURITY PROTOCOL MODE NATAH Transport NAH Tunnel NESP Transport Y*ESP Tunnel YAB

The BM2022w can distinguish up to 48 incoming SAs because you can select between three encryption algorithms (DES, 3DES and AES), two authentication algorithms (MD5 and SHA1) and eight key groups when you configure a VPN rule (see Section 8.11.1 on page 141). The ID type and content act as an extra level of identification for incoming SAs.The type of ID can be a domain name, an IP address or an e-mail address. The content is the IP address, domain name, or e-mail address. 8.12.7.1  ID Type and Content ExamplesTwo IPSec routers must have matching ID type and content configuration in order to set up a VPN tunnel. The two BM2022ws in this example can complete negotiation and establish a VPN tunnel.The two BM2022ws in this example cannot complete their negotiation because BM2022w B’s Local ID type is IP, but BM2022w A’s Remote ID type is set to E-mail. An “ID mismatched” message displays in the IPSEC LOG. 8.12.8  Pre-Shared KeyA pre-shared key identifies a communicating party during a phase 1 IKE negotiation (see Section8.12.3 on page 151 for more on IKE phases). It is called “pre-shared” because you have to share it with another party before you can communicate with them over a secure connection.Table 65   Local ID Type and Content FieldsLOCAL ID TYPE= CONTENT=IP Type the IP address of your computer.DNS Type a domain name (up to 31 characters) by which to identify this BM2022w.E-mail Type an e-mail address (up to 31 characters) by which to identify this BM2022w.The domain name or e-mail address that you use in the Local ID Content field is used for identification purposes only and does not need to be a real domain name or e-mail address.Table 66   Matching ID Type and Content Configuration ExampleBM2022w A BM2022w BLocal ID type: E-mail Local ID type: IPLocal ID content: tom@yourcompany.com Local ID content: 1.1.1.2Remote ID type: IP Remote ID type: E-mailRemote ID content: 1.1.1.2 Remote ID content: tom@yourcompany.comTable 67   Mismatching ID Type and Content Configuration ExampleBM2022W A BM2022W BLocal ID type: IP Local ID type: IPLocal ID content: 1.1.1.10 Local ID content: 1.1.1.2Remote ID type: E-mail Remote ID type: IPRemote ID content: aa@yahoo.com Remote ID content: 1.1.1.0
 Chapter 8 SecurityBM2022w User’s Guide 1558.12.9  Diffie-Hellman (DH) Key GroupsDiffie-Hellman (DH) is a public-key cryptography protocol that allows two parties to establish a shared secret over an unsecured communications channel. Diffie-Hellman is used within IKE SA setup to establish session keys. 768-bit, 1024-bit 1536-bit, 2048-bit, and 3072-bit Diffie-Hellman groups are supported. Upon completion of the Diffie-Hellman exchange, the two peers have a shared secret, but the IKE SA is not authenticated. For authentication, use pre-shared keys.
