Chapter 15 The Firewall ScreensMAX-207HW2R User’s Guide 15115.4 Technical ReferenceThe following section contains additional technical information about the MAX-207HW2R features described in this chapter.15.4.1 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.15.4.2 Guidelines For Enhancing Security With Your Firewall1Change the default password via web configurator.2Think about access control before you connect to the network in any way.3Limit who can access your router.4Don't enable any local service (such as telnet or FTP) that you don't use. Any enabled service could present a potential security risk. A determined hacker might be able to find creative ways to misuse the enabled services to access the firewall or the network.5For local services that are enabled, protect against misuse. Protect by configuring the services to communicate only with specific peers, and protect by configuring rules to block packets for the services at specific interfaces.6Protect against IP spoofing by making sure the firewall is active.7Keep the firewall in a secured (locked) room.15.4.3 The “Triangle Route” ProblemA traffic route is a path for sending or receiving data packets between two Ethernet devices. You may have more than one connection to the Internet (through one or more ISPs). If an alternate gateway is on the LAN (and its IP address is in the same subnet as the MAX-207HW2R’s LAN IP address), the
Chapter 15 The Firewall ScreensMAX-207HW2R User’s Guide152“triangle route” (also called asymmetrical route) problem may occur. The steps below describe the “triangle route” problem. 1A computer on the LAN initiates a connection by sending out a SYN packet to a receiving server on the WAN.2The MAX-207HW2R reroutes the SYN packet through Gateway A on the LAN to the WAN. 3The reply from the WAN goes directly to the computer on the LAN without going through the MAX-207HW2R. As a result, the MAX-207HW2R resets the connection, as the connection has not been acknowledged.Figure 68 “Triangle Route” Problem15.4.3.1 Solving the “Triangle Route” ProblemIf you have the MAX-207HW2R allow triangle route sessions, traffic from the WAN can go directly to a LAN computer without passing through the MAX-207HW2R and its firewall protection. Another solution is to use IP alias. IP alias allows you to partition your network into logical sections over the same Ethernet interface. Your MAX-207HW2R supports up to three logical LAN interfaces with the MAX-207HW2R being the gateway for each logical network. It’s like having multiple LAN networks that actually use the same physical cables and ports. By putting your LAN and Gateway A in different subnets, all returning network traffic must pass through the MAX-207HW2R to your LAN. The following steps describe such a scenario.1A computer on the LAN initiates a connection by sending a SYN packet to a receiving server on the WAN. 2The MAX-207HW2R reroutes the packet to Gateway A, which is in Subnet 2.
Chapter 15 The Firewall ScreensMAX-207HW2R User’s Guide 1533The reply from the WAN goes to the MAX-207HW2R. 4The MAX-207HW2R then sends it to the computer on the LAN in Subnet 1.Figure 69 IP Alias

You must connect using a compatible web browser in order to use it.High Speed Wireless Internet Access The MAX-207HW2R is ideal for high-speed wireless Internet browsing. WiMAX (Worldwide Interoperability for Microwave Access) is a wireless networking standard providing high-bandwidth, wide-range secured wireless service. The MAX-207HW2R is a WiMAX mobile station (MS) compatible with the IEEE 802.16e standard. Firewall The MAX-207HW2R is a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The MAX-207HW2R’s firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs.Content Filtering The MAX-207HW2R can block access to web sites containing specified keywords. You can define time periods and days during which content filtering is enabled and include or exclude a range of users on the LAN from content filtering.Network Address Translation (NAT) Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet).Table 67 Radio Specifications (continued)
Chapter 20 Product SpecificationsMAX-207HW2R User’s Guide 175Universal Plug and Play (UPnP) Your device and other UPnP enabled devices can use the standard TCP/IP protocol to dynamically join a network, obtain an IP address and convey their capabilities to each other.Dynamic DNS Support With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider.DHCP DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. Your device has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. Your device can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.IP Alias IP alias allows you to partition a physical network into logical networks over the same Ethernet interface. Your device supports three logical LAN interfaces via its single physical Ethernet interface with the your device itself as the gateway for each LAN network.Multiple SIP Accounts You can configure multiple voice (SIP) accounts.SIP ALG Your device is a SIP Application Layer Gateway (ALG). It allows VoIP calls to pass through NAT for devices behind it (such as a SIP-based VoIP software application on a computer). Dynamic Jitter Buffer The built-in adaptive buffer helps to smooth out the variations in delay (jitter) for voice traffic (up to 60 ms). This helps ensure good voice quality for your conversations.Voice Activity Detection/Silence Suppression Voice Activity Detection (VAD) reduces the bandwidth that a call uses by not transmitting when you are not speaking. Comfort Noise Generation Your device generates background noise to fill moments of silence when the other device in a call stops transmitting because the other party is not speaking (as total silence could easily be mistaken for a lost connection). Echo Cancellation You device supports G.168 of at least 24 ms.This an ITU-T standard for eliminating the echo caused by the sound of your voice reverberating in the telephone receiver while you talk.Time and Date Get the current time and date from an external server when you turn on your MAX-207HW2R. You can also set the time manually.Logging Use the MAX-207HW2R’s logging feature to view connection history, surveillance logs, and error messages.Codecs Enhanced Variable Rate Codec (EVRC), G.711 (PCM µ-law and a-law), G.729a, and G.723.1 Table 68 Firmware Specifications (continued)FEATURE DESCRIPTION

If you do not enter the correct number, you cannot pickup the call. This means that only someone who knows the number you have chosen can pick up the call. You can have more than one call on hold at the same time, but you must give each call a different number.Call Return With call return, you can place a call to the last number that called you (either answered or missed). The last incoming call can be through either SIP or PSTN.Country Code Phone standards and settings differ from one country to another, so the settings on your MAX-207HW2R must be configured to match those of the country you are in. The country code feature allows you to do this by selecting the country from a list rather than changing each setting manually. Configure the country code feature when you move the MAX-207HW2R from one country to another.Do not Disturb (DnD) This feature allows you to set your phone not to ring when someone calls you. You can set each phone independently using its keypad, or configure global settings for all phones using the command line interpreter.Auto Dial You can set the MAX-207HW2R to automatically dial a specified number immediately whenever you lift a phone off the hook. Use the Web Configurator to set the specified number. Use the command line interpreter to have the MAX-207HW2R wait a specified length of time before dialing the number. Phone config The phone configuration table allows you to customize the phone keypad combinations you use to access certain features on the MAX-207HW2R, such as call waiting, call return, call forward, etc. The phone configuration table is configurable in command interpreter mode.Table 69 Standards Supported (continued)STANDARD DESCRIPTION
Chapter 20 Product SpecificationsMAX-207HW2R User’s Guide178Firmware update enable / disable If your service provider uses this feature, you hear a recorded message when you pick up the phone when new firmware is available for your MAX-207HW2R. Enter *99# in your phone’s keypad to have the MAX-207HW2R upgrade the firmware, or enter #99# to not upgrade. If your service provider gave you different numbers to use, enter them instead. If you enter the code to not upgrade, you can make a call as normal. You will hear the recording again each time you pick up the phone, until you upgrade. Call waiting This feature allows you to hear an alert when you are already using the phone and another person calls you. You can then either reject the new incoming call, put your current call on hold and receive the new incoming call, or end the current call and receive the new incoming call.Call forwarding With this feature, you can set the MAX-207HW2R to forward calls to a specified number, either unconditionally (always), when your number is busy, or when you do not answer. You can also forward incoming calls from one specified number to another.Caller ID The MAX-207HW2R supports caller ID, which allows you to see the originating number of an incoming call (on a phone with a suitable display).REN A Ringer Equivalence Number (REN) is used to determine the number of devices (like telephones or fax machines) that may be connected to the telephone line. Your device has a REN of three, so it can support three devices per telephone port.QoS (Quality of Service) Quality of Service (QoS) mechanisms help to provide better service on a per-flow basis. Your device supports Type of Service (ToS) tagging and Differentiated Services (DiffServ) tagging.

MAX-207HW2R User’s Guide 183APPENDIX A WiMAX SecurityWireless security is vital to protect your wireless communications. Without it, information transmitted over the wireless network would be accessible to any networking device within range.User Authentication and Data EncryptionThe WiMAX (IEEE 802.16) standard employs user authentication and encryption to ensure secured communication at all times.User authentication is the process of confirming a user’s identity and level of authorization. Data encryption is the process of encoding information so that it cannot be read by anyone who does not know the code. WiMAX uses PKMv2 (Privacy Key Management version 2) for authentication, and CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol) for data encryption. WiMAX supports EAP (Extensible Authentication Protocol, RFC 2486) which allows additional authentication methods to be deployed with no changes to the base station or the mobile or subscriber stations.PKMv2PKMv2 is a procedure that allows authentication of a mobile or subscriber station and negotiation of a public key to encrypt traffic between the MS/SS and the base station. PKMv2 uses standard EAP methods such as Transport Layer Security (EAP-TLS) or Tunneled TLS (EAP-TTLS) for secure communication. In cryptography, a ‘key’ is a piece of information, typically a string of random numbers and letters, that can be used to ‘lock’ (encrypt) or ‘unlock’ (decrypt) a message. Public key encryption uses key pairs, which consist of a public (freely available) key and a private (secret) key. The public key is used for encryption and the private key is used for decryption. You can decrypt a message only if you have the private key. Public key certificates (or ‘digital IDs’) allow users to verify each other’s identity.
Appendix A WiMAX SecurityMAX-207HW2R User’s Guide184RADIUSRADIUS is based on a client-server model that supports authentication, authorization and accounting. The base station 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 base station acts as a message relay between the MS/SS and the network RADIUS server. Types of RADIUS MessagesThe following types of RADIUS messages are exchanged between the base station and the RADIUS server for user authentication:• Access-RequestSent by an base station 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 base station sends a proper response from the user and then sends another Access-Request message. The following types of RADIUS messages are exchanged between the base station and the RADIUS server for user accounting:•Accounting-RequestSent by the base station 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
Appendix A WiMAX SecurityMAX-207HW2R User’s Guide 185the network. In addition to the shared key, password information exchanged is also encrypted to protect the network from unauthorized access. DiameterDiameter (RFC 3588) is a type of AAA server that provides several improvements over RADIUS in efficiency, security, and support for roaming. Security AssociationThe set of information about user authentication and data encryption between two computers is known as a security association (SA). In a WiMAX network, the process of security association has three stages.• Authorization request and replyThe MS/SS presents its public certificate to the base station. The base station verifies the certificate and sends an authentication key (AK) to the MS/SS.• Key request and replyThe MS/SS requests a transport encryption key (TEK) which the base station generates and encrypts using the authentication key. • Encrypted trafficThe MS/SS decrypts the TEK (using the authentication key). Both stations can now securely encrypt and decrypt the data flow.CCMPAll traffic in a WiMAX network is encrypted using CCMP (Counter Mode with Cipher Block Chaining Message Authentication Protocol). CCMP is based on the 128-bit Advanced Encryption Standard (AES) algorithm. ‘Counter mode’ refers to the encryption of each block of plain text with an arbitrary number, known as the counter. This number changes each time a block of plain text is encrypted. Counter mode avoids the security weakness of repeated identical blocks of encrypted text that makes encrypted data vulnerable to pattern-spotting.‘Cipher Block Chaining Message Authentication’ (also known as CBC-MAC) ensures message integrity by encrypting each block of plain text in such a way that its encryption is dependent on the block before it. This series of ‘chained’ blocks creates a message authentication code (MAC or CMAC) that ensures the encrypted data has not been tampered with.
Appendix A WiMAX SecurityMAX-207HW2R User’s Guide186Authentication The MAX-207HW2R supports EAP-TTLS authentication.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 (with EAP-TLS digital certifications are needed by both the server and the wireless clients for mutual authentication). 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.

MAX-207HW2R User’s Guide 225APPENDIX D 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, 192.168.100.1). 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 D IP Addresses and SubnettingMAX-207HW2R User’s Guide226The 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 122 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 72 IP Address Network Number and Host ID Example1ST OCTET:(192)2ND OCTET:(168)3RD OCTET:(1)4TH OCTET(2)IP Address (Binary) 11000000 10101000 00000001 00000010Subnet Mask (Binary) 11111111 11111111 11111111 00000000Network Number 11000000 10101000 00000001Host ID 00000010
Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide 227By 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).As these two IP addresses cannot be used for individual hosts, calculate the maximum number of possible hosts in a network as follows:Table 73 Subnet MasksBINARYDECIMAL1ST OCTET 2ND OCTET 3RD OCTET 4TH OCTET8-bit mask 11111111 00000000 00000000 00000000 255.0.0.016-bit mask 11111111 11111111 00000000 00000000 255.255.0.024-bit mask 11111111 11111111 11111111 00000000 255.255.255.029-bit mask 11111111 11111111 11111111 11111000 255.255.255.248Table 74 Maximum Host NumbersSUBNET MASK HOST ID SIZE MAXIMUM NUMBER OF HOSTS8 bits 255.0.0.0 24 bits 224 – 2 1677721416 bits 255.255.0.0 16 bits 216 – 2 6553424 bits 255.255.255.0 8 bits 28 – 2 25429 bits 255.255.255.248 3 bits 23 – 2 6
Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide228NotationSince 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. SubnettingYou 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.Table 75 Alternative Subnet Mask NotationSUBNET MASK ALTERNATIVE NOTATION LAST OCTET (BINARY) LAST OCTET (DECIMAL)255.255.255.0 /24 0000 0000 0255.255.255.128 /25 1000 0000 128255.255.255.192 /26 1100 0000 192255.255.255.224 /27 1110 0000 224255.255.255.240 /28 1111 0000 240255.255.255.248 /29 1111 1000 248255.255.255.252 /30 1111 1100 252
Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide 229The following figure shows the company network before subnetting. Figure 123 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 192.168.100.128 /25.
Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide230The following figure shows the company network after subnetting. There are now two sub-networks, A and B. Figure 124 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 192.168.100.127 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 192.168.100.1 and the highest is 192.168.100.126. Similarly, the host ID range for subnet B is 192.168.100.129 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 D IP Addresses and SubnettingMAX-207HW2R User’s Guide 231Each 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 D IP Addresses and SubnettingMAX-207HW2R User’s Guide 233Configuring 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 MAX-207HW2R. Once you have decided on the network number, pick an IP address for your MAX-207HW2R that is easy to remember (for instance, 192.168.100.1) 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 MAX-207HW2R 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 MAX-207HW2R unless you are instructed to do otherwise.3255.255.224.0 (/19) 881904255.255.240.0 (/20) 16 40945255.255.248.0 (/21) 32 20466255.255.252.0 (/22) 64 10227255.255.254.0 (/23) 128 5108255.255.255.0 (/24) 256 2549255.255.255.128 (/25) 512 12610 255.255.255.192 (/26) 1024 6211 255.255.255.224 (/27) 2048 3012 255.255.255.240 (/28) 4096 1413 255.255.255.248 (/29) 8192 614 255.255.255.252 (/30) 16384 215 255.255.255.254 (/31) 32768 1Table 82 16-bit Network Number Subnet Planning (continued)NO. “BORROWED” HOST BITS SUBNET MASK NO.

Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide234Private 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.IP Address ConflictsEach device on a network must have a unique IP address. Devices with duplicate IP addresses on the same network will not be able to access the Internet or other resources. The devices may also be unreachable through the network. Conflicting Computer IP Addresses ExampleMore than one device can not use the same IP address. In the following example computer A has a static (or fixed) IP address that is the same as the IP address that a DHCP server assigns to computer B which is a DHCP client. Neither can access the Internet. This problem can be solved by assigning a different static IP
Appendix D IP Addresses and SubnettingMAX-207HW2R User’s Guide 235address to computer A or setting computer A to obtain an IP address automatically. Figure 125 Conflicting Computer IP Addresses ExampleConflicting Router IP Addresses ExampleSince a router connects different networks, it must have interfaces using different network numbers. For example, if a router is set between a LAN and the Internet (WAN), the router’s LAN and WAN addresses must be on different subnets. In the following example, the LAN and WAN are on the same subnet. The LAN computers cannot access the Internet because the router cannot route between networks.Figure 126 Conflicting Computer IP Addresses ExampleConflicting Computer and Router IP Addresses ExampleMore than one device can not use the same IP address. In the following example, the computer and the router’s LAN port both use 192.168.100.1 as the IP address.

MAX-207HW2R User’s Guide 237APPENDIX E Importing CertificatesThis appendix shows you how to import public key certificates into your web browser. Public key certificates are used by web browsers to ensure that a secure web site is legitimate. When a certificate authority such as VeriSign, Comodo, or Network Solutions, to name a few, receives a certificate request from a website operator, they confirm that the web domain and contact information in the request match those on public record with a domain name registrar. If they match, then the certificate is issued to the website operator, who then places it on the site to be issued to all visiting web browsers to let them know that the site is legitimate.Many ZyXEL products, such as the NSA-2401, issue their own public key certificates. These can be used by web browsers on a LAN or WAN to verify that they are in fact connecting to the legitimate device and not one masquerading as it. However, because the certificates were not issued by one of the several organizations officially recognized by the most common web browsers, you will need to import the ZyXEL-created certificate into your web browser and flag that certificate as a trusted authority.Note: You can see if you are browsing on a secure website if the URL in your web browser’s address bar begins with https:// or there is a sealed padlock icon ( ) somewhere in the main browser window (not all browsers show the padlock in the same location.)In this appendix, you can import a public key certificate for:• Internet Explorer on page 238•Firefox on page 248•Opera on page 254• Konqueror on page 262

MAX-207HW2R User’s Guide 269APPENDIX F SIP PassthroughEnabling/Disabling the SIP ALGYou can turn off the MAX-207HW2R SIP ALG to avoid retranslating the IP address of an existing SIP device that is using STUN. If you want to use STUN with a SIP client device (a SIP phone or IP phone for example) behind the MAX-207HW2R, use the ip alg disable ALG_SIP command to turn off the SIP ALG.Signaling Session TimeoutMost SIP clients have an “expire” mechanism indicating the lifetime of signaling sessions. The SIP UA sends registration packets to the SIP server periodically and keeps the session alive in the MAX-207HW2R. If the SIP client does not have this mechanism and makes no call during the MAX-207HW2R SIP timeout default (60 minutes), the MAX-207HW2R SIP ALG drops any incoming calls after the timeout period. You can use the ip alg siptimeout command to change the timeout value.Audio Session TimeoutIf no voice packets go through the SIP ALG before the timeout period default (5 minutes) expires, the SIP ALG does not drop the call but blocks all voice traffic and deletes the audio session. You cannot hear anything and you will need to make a new call to continue your conversation.
