Page 38 ONFIGURING THE LAN P ORTS This section describes how to configure IP properties for the interfaces on the ADSL Barricade that communicate with your LAN computers. Connecting via Ethernet If you are using the ADSL Barricade with multiple PCs on your LAN, you must connect the LAN via an Ethernet hub to the device's LAN port, called [eth-0].
Page 39: Configuring The Lan Ports
Configuring the LAN Ports If your network uses a DHCP server (other than the ADSL Barricade) to assign IP addresses, you can configure the device to accept and use a LAN IP address assigned by that server. Similarly, if your ISP performs DHCP serving for your network, you can configure the device to accept an IP address assigned from the ISP's server.
Page 40: Configuring The Lan Port Ip Address
Configuring the LAN Port IP Address The LAN Configuration table displays the following settings: Setting Description System Mode: This setting is preconfigured for your device, such as [Routing mode], [Bridging mode], or both modes simultaneously. This setting is not user-configurable. This setting provides options for how the device’s LAN port LAN Address: is assigned an IP address:...
Page 41 Configuring the LAN Ports The IP address you assign must be in the same subnet as your LAN computers that connect to this port (that is, the network ID portion of their IP addresses and their subnet masks must be the same). See IP Addresses, Network Masks and Subnets on page 167 for an explanation of IP addresses and network masks.
Page 42 Configuring the LAN Port IP Address • If you enabled the DHCP service, the ADSL Barricade will initiate a request for an IP address from your LAN's DHCP server. If a different IP address is assigned than the one that was previously configured, your current connection will be terminated.
Page 43 IEWING YSTEM IP A DDRESSES AND ERFORMANCE TATISTICS The interface on the ADSL Barricade that communicates with other network and Internet devices are identified by unique Internet protocol (IP) addresses.

You will not typically need to view thi s data, but you may find it helpful when working with your ISP to diagnose network and Internet data transmission problems.
Page 46: Host Configuration Protocol
ONFIGURING YNAMIC ONFIGURATION ROTOCOL You can configure your network and ADSL Barricade to use the Dynamic Host Configuration Protocol (DHCP). This section provides an overview of DHCP and instructions for implementing it on your network. Overview of DHCP What is DHCP? DHCP is a protocol that enables network administrators to centrally manage the assignment and distribution of IP information to computers on a network.
Page 47: Why Use Dhcp
Configuring Dynamic Host Configuration Protocol The DHCP server draws from a defined pool of IP addresses and leases them for a specified amount of time to your computers when they request an Internet session. It monitors, collects, and redistributes the addresses as needed. On a DHCP-enabled network, the IP information is assigned dynamically rather than statically.
Page 48: Configuring Dhcp Server
Configuring DHCP Server • If you have another PC or device on your network that is already performing the DHCP server function, then you can configure the device's LAN port to be a DHCP client of that server (as are your PCs). This configuration is described in Configuring the LAN Ports.
Page 49 Configuring Dynamic Host Configuration Protocol You can create up to two pools. The pools can maintain a combined total of 254 IP addresses. For example, you can configure only one pool with addresses in the range 192.168.1.2 through 192.168.1.255, or two pools with the following address ranges: Pool 0: 192.168.1.2 through 192.168.1.128 Pool 1: 192.168.1.129 through 192.168.1.255...
Page 50: Adding Dhcp Server Address Pools
Configuring DHCP Server With this configuration, you could create the following two pools: Pool 0: 192.168.1.2 through 192.168.1.11 Pool 1: 192.168.2.2 through 192.168.2.2 The DHCP server would automatically distribute the Pool 0 addresses only to computers connected to the interface in the same subnet as these addresses-the LAN interface, eth-0.

Page 58: Configuring Network Address Translation
ONFIGURING ETWORK DDRESS RANSLATION This section provides an overview of Network Address Translation (NAT) and instructions for modifying the default configuration on your device. Overview of NAT Network Address Translation is a method for disguising the private IP addresses you use on your LAN as the public IP address you use on the Internet.
Page 59 Configuring Network Address Translation Definition: An IP data packet contains bits of data bundled together in a specific format for efficient transmission over the Internet. Such packets are the building blocks of all Internet communication. Each packet contains header information that identifies the IP address of the computer that initiates the communication (the source IP address), the port number that the router associates with that...
Page 60: Viewing Nat Global Settings
Viewing NAT Global Settings and Statistics • They provide a measure of security for you LAN by enabling you to assign private IP addresses and then have these and the source port numbers swapped out before your computers access the Internet. The type of NAT function described above is called [Network Address Port Translation (NAPT)].
Page 61 Configuring Network Address Translation The [NAT Configuration] page contains the following elements: • The [NAT Options] drop-down list will provide access to the [NAT Configuration] page and [NAT Global Information] table (shown by default and in Figure 16), the [Network Address Translation (NAT) Rule Configuration] page (see Figure 18) and the [NAT Translations] page (see Figure 20).

Page 67: Adding Nat Rules
Configuring Network Address Translation Adding NAT Rules This section explains how to create rules for each NAT flavor. Note: You cannot edit existing NAT rules. To change a rule setup, delete it and add a new rule with the modified settings.
Page 68 Adding NAT Rules Figure 22. NAT Rule - Add Page (NAPT Flavor) 4. Enter a [Rule ID]. The Rule ID determines the order in which rules are invoked (the lowest numbered rule is invoked first, and so on). If you define two or more rules that act on the same set of IP addresses, be sure to assign the Rule ID so that the higher priority rules are invoked first.
Page 69 Configuring Network Address Translation 6. In the [Local Address From:] field and [Local Address To:] fields, type the starting and ending IP addresses, respectively, of the range of private addresses you use on your network that you want to have translated. You can specify that data from all LAN addresses should be translated by typing [0] (zero) in each [From] field and [255] in each [To] field.
Page 70: The Rdr Rule: Allowing External Access To A Lan Computer
Adding NAT Rules The RDR rule: Allowing external access to a LAN computer You can create an RDR rule to make a computer on your LAN, such as a Web or FTP server, available to Internet users without requiring you to obtain a public IP address for that computer. The computer's private IP address is translated to your public IP address in all incoming and outgoing data packets.
Page 71 Configuring Network Address Translation To an external Internet user then, it appears as if your Web server uses your public IP address. Figure 23. NAT Rule - Add Page (RDR Flavor) Follow the following instructions to add an RDR rule (see steps 1-4 under The NAPT Rule for specific instructions corresponding to steps 1 and 2 below): 1.
Page 72 Adding NAT Rules 4. In the [Local Address From:] and [Local Address To:] fields, type the same private IP address, or the lowest and highest addresses in a range: • If you type the same IP address in both fields, incoming traffic that matches the criteria you specify in steps 5 and 6 will be redirected to that IP address.
Page 73 Configuring Network Address Translation You can specify a range using the [From/To] fields if you want the rule to apply to a range of port types, or enter the same port number in both fields. A port ID identifies the specific function of the computer connected to it, and therefore can limit the types of data that pass to and from the computer.
Page 74: The Basic Rule: Performing 1:1 Translations
Adding NAT Rules The Basic rule: Performing 1:1 translations The Basic flavor translates the private (LAN-side) IP address to a public (WAN-side) address, like NAPT rules. However, unlike NAPT rules, Basic rules do not translate the port numbers in the packet header; they are passed through untranslated. Therefore, the Basic rule does not provide the same level of security as the NAPT rule.
Page 75 Configuring Network Address Translation This selection specifies which type of Internet communication will be subject to this translation rule. You can select [ANY] if the rule applies to all data. Or, select [TCP], [UDP], [ICMP], or a number from [1-255] that represents the Internet Assigned Numbers Authority (IANA)-specified protocol number.
Page 76: The Filter Rule: Configuring A Basic Rule With Additional Criteria
Adding NAT Rules The Filter rule: Configuring a BASIC rule with additional criteria Like the BASIC flavor, the Filter flavor translates public and private IP addresses on a one-to-one basis. The Filter flavor extends the capability of the BASIC rule. Refer to The BASIC Rule on page 71 for a general description.
Page 77 Configuring Network Address Translation 2. Select the interface ([IF Name:]) on which this rule will be effective. 3. Select a [Protocol:] to which this rule applies, or choose [ANY]. This selection specifies which type of Internet communication will be subject to this translation rule. You can select [ANY] if the rule applies to all data.
Page 78: The Bimap Rule: Performing Two-Way Translations
Adding NAT Rules If you enter only the network ID portion of the destination address, then the rule will apply to outbound traffic to all computers on network. 7. In the [Destination Port From:] field, type a port ID number if you want the rule to apply only to outbound traffic to servers of this type.
Page 79 Configuring Network Address Translation Bimap rules can be used to provide external access to a LAN device. They do not provide the same level of security as RDR rules, because RDR rules also reroute incoming packets based on the port ID. Bimap rules do not account for the port number, and therefore allow external access regardless of the destination port type specified in the incoming packet.
Page 80: The Pass Rule: Allowing Specific Addresses To Pass Through Untranslated
Adding NAT Rules The Pass rule: Allowing specific addresses to pass through untranslated You can create a Pass rule to allow a range of IP addresses to remain untranslated when another rule would otherwise do so. Figure 27. NAT Rule - Add Page (Pass Flavor) The Pass rule must be assigned a rule ID that is a lower number than the ID assigned to the rule it is intended to pass.
Page 81 Configuring Network Address Translation 3. In the [Local Address From:] and [Local Address To:] fields, type the lowest and highest IP addresses that define the range of private address you want to be passed without translation. If you want the Pass rule to act on only one address, type that address in both fields.
Page 82: About Dns
ONFIGURING ERVER DDRESSES About DNS Domain Name System (DNS) servers map the user-friendly domain names that users type into their Web browsers (e.g. yahoo.com) to the equivalent numerical IP addresses that are used for Internet routing. When a PC user types a domain name into a browser, the PC must first send a request to a DNS server to obtain the equivalent IP addresses.
Page 83: Configuring Dns Relay
Configuring DNS Server Addresses • Dynamically from a DHCP pool: You can configure the DHCP Server feature on the ADSL Barricade and create an address pool that specifies the DNS addresses to be distributed to the PCs. Refer to Configuring Dynamic Host Configuration Protocol for instructions on creating DHCP address pools.

Page 86: Configuring Ip Routes
IP R ONFIGURING OUTES You can use the Configuration Manager to define specific routes for your Internet and network data. This section describes basic routing concepts and provides instructions for creating routes. Note: Most users do not need to define IP routes. Overview of IP Routes The essential challenge of a router is: when it receives data intended for a particular destination, which device should it send...
Page 87: Hops And Gateways
Configuring IP Routes In comparison, when your computer initiates communication over the Internet, such as viewing a web page connecting to a web server, the data it sends out includes the IP address of the destination computer (the phone number). All your outgoing requests first go to the same router at your ISP (the first switchboard).
Page 88: Using Ip Routes To Define Default Gateways
Overview of IP Routes Using IP routes to define default gateways IP routes are defined on computers, routers, and other IP-enabled devices to instruct them which hop to take, or which gateway to use, to help forward data along to its specified destination. If no IP route is defined for a destination, then IP data is passed to a predetermined default gateway.
Page 89: Viewing The Ip Routing Table
Configuring IP Routes • On the ADSL Barricade itself, a default gateway is defined to direct all outbound Internet traffic to a router at your ISP. This default gateway is assigned automatically by your ISP whenever the device negotiates an Internet connection. (The process for adding a default route is described on page 88.) You may need to define routes if your home setup includes two or more networks or subnets, if you connect to two or more ISP...
Page 90 Viewing the IP Routing Table The [IP Route Table] displays a row for each existing route. These include routes that were predefined on the device, routes you may have added, and routes that the device has identified automatically through communication with other devices. The following table defines the fields in the [IP Route Table].
Page 91: Adding Ip Routes
Configuring IP Routes Adding IP Routes Follow these instructions to add an IP route to the routing table. 1. From the [IP Route Table] page, click [Add]. The [IP Route - Add] page appears, as shown in Figure 30. Figure 30. IP Route - Add Page 2.

Page 93: Configuring The Routing Information Protocol
ONFIGURING THE OUTING NFORMATION ROTOCOL The ADSL Barricade can be configured to communicate with other routing devices to determine the best path for sending data to its intended destination. Routing devices communicate this information using a variety of IP protocols. This section describes how to configure the ADSL Barricade to use one of these, called the Routing Information Protocol (RIP).
Page 94: When Should You Configure Rip
Configuring the Routing Information Protocol When should you configure RIP? Most small home or office networks do not need to use RIP; they have only one router, such as the ADSL Barricade, and one path to an ISP. In these cases, there is no need to share routes, because all Internet data from the network is sent to the same ISP gateway.
Page 95 Configuring the ADSL Barricade's Interfaces with RIP 1. Log into the Configuration Manager, click the [Services] tab, and then click [RIP] in the task bar. The [Routing Information Protocol (RIP) Configuration] page appears, as shown in Figure 31. Figure 31. RIP Configuration Page The page contains radio buttons for [Enable] or [Disable] the RIP feature and a table listing interfaces on which the protocol is currently running.
Page 96 Configuring the Routing Information Protocol 3. In the [IF Name] column, select the name of the interface on which you want to enable RIP. For communication with RIP-enabled devices on your LAN, select [eth-0] or the name of the appropriate virtual Ethernet interface. For communication with your ISP or a remote LAN, select the corresponding [ppp], [eoa], or other WAN interface.
Page 97 Configuring the ADSL Barricade's Interfaces with RIP RIP version 2 is the preferred selection because it supports classless IP addresses (which are used to create subnets) and other features. Select [RIP2] if all other routing devices on the autonomous network support this version of the protocol. 6.

Figure 32. RIP Global Statistics Page You can click [Clear] to reset all statistics to zero and [Refresh] to display any newly accumulated data.
Page 99 ONFIGURING THE IRTUAL IRCUIT As your LAN computers access the Internet via the ADSL Barricade, data is exchanged with your ISP through a complex network of telephone switches, Internet routers, servers, and other specialized hardware. These various devices communicate using a common language, or protocol, called Asynchronous Transfer Mode (ATM).

Page 119: Configuring Ipoa Interfaces
ONFIGURING NTERFACES This section describes how to configure an IPoA (Internet Protocol-over-ATM) interface on the ADSL Barricade. An IPoA interface can be used to exchange IP packets over the ATM network, without using an underlying Ethernet over ATM (EOA) connection. Typically, this type of interface is used only in product development and test environments, to eliminate unneeded variables when evaluating IP layer processing.
Page 120 Configuring IPoA Interfaces The following table describes the fields on this page: Field Description Interface This is the name the software uses to identify the IPoA interface. RFC 1577 If 1577 is selected the PPP packets are encapsulated according to RFC 1577 for transmission over an ATM link. If 1577 is not selected, RFC 1577 is not applied under this option.
Page 121: Adding Ipoa Interfaces
Adding IPoA Interfaces Field Description Gateway Address This is the external IP address that the ADSL Barricade communicates with via the IPoA interface to gain access to the Internet. This is typically an ISP server. Status A green or red ball will appear to indicate that the interface is currently up or down, respectively.

Page 123: Configuring Bridging
ONFIGURING RIDGING The ADSL Barricade can be configured to act as a bridging device between your LAN and your ISP. Bridges are devices that enable two or more networks to communicate as if they are two segments of the same physical LAN. This section describes how to configure the ADSL Barricade to operate as a bridge.
Page 124 Configuring Bridging On the receiving network, a LAN protocol such as Ethernet takes over, helping the packet reaches its destination. When the bridge does not recognize a packet's destination hardware ID, it broadcasts the packet through all of its interfaces – to each network it is attached to.
Page 125: When To Use The Bridging Feature
When to Use the Bridging Feature When to Use the Bridging Feature Although the ADSL Barricade is preconfigured to serve as a router for providing Internet connectivity to your LAN, there are several instances in which you may also want to configure bridging: •...

Page 132: Configuring Ip Filters And Blocked Protocols
IP F ONFIGURING ILTERS LOCKED ROTOCOLS This section describes two Configuration Manager features that enable you to control the data passing through your network: • The IP filter feature enables you to create rules to block attempts by certain computers on your LAN to access certain types of data or Internet locations.
Page 133: Viewing Your Ip Filter Configuration
Configuring IP Filters and Blocked Protocols If the packet matches the criteria established in a rule, the packet can either be accepted (forwarded towards its destination), or denied (discarded), depending on the action specified in the rule. Viewing Your IP Filter Configuration To view your current IP filter configuration, log into [Configuration Manager], click the [Services] tab, and then click [IP Filter] in the task bar.
Page 134: Configuring Ip Filter Global Settings
Configuring IP Filters Configuring IP Filter Global Settings The [IP Filter Configuration] page enables you to configure the following global IP filter settings. [Security Level:] This setting determines which IP filter rules take effect, based on the security level specified in each rule. For example, when [High] is selected, only those rules that are assigned a High security value will be effective.
Page 135 Configuring IP Filters and Blocked Protocols A Private interface connects to your LAN, such as the Ethernet interface. Packets received on a private interface are subject to a less restrictive set of protections, because they originate within the network. Typically, the global setting for private interfaces is [Accept], so that LAN computers have access to the ADSL Barricade's Internet connection.
Page 136: Creating Ip Filter Rules
Configuring IP Filters Creating IP Filter Rules To create an IP filter rule, you set various criteria that must be met in order for the rule to be invoked. Use these instructions to add a new IP filter rule, and refer to the examples on page 143 for assistance: 1.
Page 137 Configuring IP Filters and Blocked Protocols 2. Enter or select data for each field that applies to your rule. The following table describes the fields: Field Description Rule ID: Each rule must be assigned a sequential ID number. Rules are processed from lowest to highest on each data packet, until a match is found.
Page 138 Configuring IP Filters Security This is the security level that must be enabled globally for this rule Level: to take affect. A rule will be active only if its security level is the same as the globally configured setting (shown on the main [IP Filter] page).
Page 139 Configuring IP Filters and Blocked Protocols Src IP These fields indicate IP address criteria for the source Address: computer(s) (from which the packet originates) and the destination computer. In the drop-down list, you can Dest IP configure the rule to be invoked on packets containing: Address: [any]: any source IP address.
Page 140 Configuring IP Filters Store State: When this option is enabled, packets are monitored for their state (i.e., whether they are the initiating packet or a subsequent packet in an ongoing communication, etc). This option provides a degree of security by blocking/dropping packets that are not received in the anticipated state.
Page 141 Configuring IP Filters and Blocked Protocols IP Frag Pkt: This field determines how the rule applies to IP packets that contain fragments. You can choose from the following options: [Yes]: The rule will be applied only to packets that contain fragments.

Configuring IP Filters and Blocked Protocols You can click [Clear] to reset the count to zero and [Refresh] to display newly accumulated data. Managing Current IP Filter Sessions When two computers communicate using the IP protocol, an IP session is created for the duration of the communication. The ADSL Barricade allows a fixed number of concurrent IP sessions.
Page 146 Configuring IP Filters The [IP Filter Session] table displays the following fields for each current IP session: Field Description Session Index This field displays the ID assigned by the system to the IP session (all sessions, whether or not they are affected by an IP filter rule, are assigned a session index).
Page 147: Blocked Protocols
Configuring IP Filters and Blocked Protocols Blocked Protocols The [Blocked Protocols] feature enables you to prevent the ADSL Barricade from passing any data that uses a particular protocol. Unlike the IP filter feature, you cannot specify additional criteria for blocked protocols, such as particular users or destinations. However, when you are certain that a particular protocol is not needed or wanted on your network, this feature provides a convenient way to discard such data before it is passed.
Page 148 Blocked Protocols The following list describes each of the available protocols. Protocol Description PPPoE This is the abbreviation of Point-to-Point Protocol over Ethernet. Many DSL modems use PPPoE to establish and maintain a connection with a service provider. PPPoE provides a means of logging in to the ISPs servers so that they can authenticate you as a customer and provide you access to the Internet.

Page 166: Ip Addresses, Network Masks And Subnets
PPENDIX IP Addresses, Network Masks and Subnets IP Addresses Note: This section pertains only to IP addresses for IPv4 (version 4 of the Internet Protocol). IPv6 addresses are not covered. This section assumes basic knowledge of binary numbers, bits, and bytes. For details on this subject, see Appendix B on page 173.
Page 167 Appendix A • Host ID: identifies a particular computer or device on the network. The first part of every IP address contains the network ID, and the rest of the address contains the host ID. The length of the network ID depends on the network's class (see following section).
Page 168: Network Classes
Network classes Network classes The three commonly used network classes are A, B and C. (There is also a class D but it has a special use beyond the scope of this discussion.) These classes have different uses and characteristics. Class A networks are the Internet's largest networks, each with room for over 16 million hosts.
Page 169: Subnet Masks
Appendix A Subnet masks Definition: A mask looks like a regular IP address, but contains a pattern of bits that tells what parts of an IP address are the network ID and what parts are the host ID: - bits set to 1 means "this bit is part of the network ID" - bits set to 0 means "this bit is part of the host ID."...
Page 170 Subnet masks These masks are: - Class A: 255.0.0.0 - Class B: 255.255.0.0 - Class C: 255.255.255.0 These are called default because they are used when a network is initially configured, at which time it has no subnets.
Page 171: Binary Numbers
PPENDIX Binary Numbers In everyday life, we use the decimal system of numbers. In decimal, numbers are written using the ten digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Computers, however, do not use decimal. Instead, they use binary. Definition (binary numbers): Binary numbers are numbers written using only the two digits 0 and 1, e.g.
Page 172: Bits And Bytes
Appendix B Bits and bytes Computers handle binary numbers by grouping them into units of distinct sizes. The smallest unit is called a bit, and the most commonly used unit is called a byte. Definition (bit and byte): A bit is a single binary digit, i.e., 0 or 1. A byte is a group of eight consecutive bits (the number of bits can vary with computers, but is almost always eight), e.g., 11011001.
