COMPACT ROUTER ADSL

1.3 Features of the Compact Router ADSL

The following sections describe the features of the ADSL Router.

High Speed Internet Access: The ADSL Router can support downstream transmission rates of up to 8Mbps and upstream transmission rates of 832 Kbps.

PPPoE Support (RFC2516): PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the ADSL Router is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE thus saving you from having to manage PPPoE clients on individual computers.

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).

10/100M Auto-negotiation Ethernet/Fast Ethernet Interface: This autonegotiation feature allows the ADSL Router to detect the speed of incoming transmissions and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.

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 client. Multiple PVC (Permanent Virtual Circuits) Support The ADSL Router supports up to 8 PVC’s.

ADSL Standards: Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8 Mbps downstream and 832 Kbps upstream. G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream. Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.994.1 and G.996.1 (for ISDN only); G.991.1;G.lite (G992.2)).Supports OAM F4/F5 loopback, AIS and RDI OAM cells.ATM Forum UNI 3.1/4.0 PVC.Supports up to 8 PVCs (UBR, CBR, VBR).Multiple Protocols over AAL5 (RFC 1483).PPP over AAL5 (RFC 2364).PPP over Ethernet (RFC 2516).

A02-RA110 Pag. 2

COMPACT ROUTER ADSL

DHCP Support: DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain TCP/IP configuration at start-up from a centralized DHCP server. The ADSL Router has built-in DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP clients. The ADSL Router can now also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients.

IP Alias: IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface. The ADSL Router supports three logical LAN interfaces via its single physical Ethernet interface with the ADSL Router itself as the gateway for each LAN network.

IP Policy Routing (IPPR): Traditionally, routing is based on the destination address only and the router takes the shortest path to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior and alter the packet forwarding based on the policy defined by the network administrator.

Protocol Support: PPP (Point-to-Point Protocol) link layer protocol.PPP over PAP (RFC 1334).PPP over CHAP (RFC 1994).RIP I/RIP II.IGMP Proxy,ICMP support,MIB II support (RFC 1213),PPPoE feature,PPPoE idle time out,PPPoE dial on demand.

Networking Compatibility: The ADSL Router is compatible with major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers.

Multiplexing:

Encapsulation: The ADSL Router series supports PPPoA (RFC 2364 - PPP over

ATM Adaptation Layer 5), RFC 1483 encapsulation over ATM, MAC encapsulated routing (ENET Encapsulation) as well as PPP over Ethernet (RFC 2516).

Network Management: Embedded Web Configurator,CLI (Command Line Interpreter),SNMP manageable,DHCP Server/Client,Built-in Diagnostic Tools. Syslog, TFTP/FTP server, firmware upgrade and configuration backup/support supported.

Diagnostics Capabilities: The ADSL Router can perform self-diagnostic tests. These tests check the integrity of the following circuitry:

The ADSL Router supports VC-based and LLC-based multiplexing.

1.4 Applications for the ADSL Router

Here are some example uses for which the ADSL Router is well suited.

1.4.1 Internet Access

The ADSL Router is the ideal high-speed Internet access solution. The Compact Router ADSL Router supports the TCP/IP protocol, which the Internet uses exclusively. It is compatible with all major ADSL DSLAM (Digital Subscriber Line Access Multiplexer) providers. A DSLAM is a rack of ADSL line cards with data multiplexed into a backbone network interface/connection (for example, T1, OC3, DS3, ATM or Frame Relay). Think of it as the equivalent of a modem rack for ADSL.

Chapter 4: Wizard Setup

This chapter provides information on the Wizard Setup screens in the web configurator.

4.1 Wizard Setup Introduction

Use the Wizard Setup screens to configure your system for Internet access settings and fill in the fields with the information in the Internet Account Information table of the Compact Guide or Read Me First. Your ISP may have already configured some of the fields in the wizard screens for you.

4.2 Encapsulation

Be sure to use the encapsulation method required by your ISP. The ADSL Router supports the following methods.

4.2.1 ENET ENCAP

The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so that they can be understood in a bridged environment. For instance, it encapsulates routed Ethernet frames into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the Ethernet Encapsulation Gateway field in the second wizard screen. You can get this information from your ISP.

4.2.2 PPP over Ethernet

PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP. The ADSL Router bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC (Permanent Virtual Circuit) which connects to ADSL Access Concentrator where the PPP session terminates. One PVC can support any number of PPP sessions from your LAN. For more information on PPPoE, see the appendix.

4.2.3 PPPoA

PPPoA stands for Point to Point Protocol over ATM Adaptation Layer 5 (AAL5). It provides access control and billing functionality in a manner similar to dial-up services using PPP. The ADSL Router encapsulates the PPP session based on

A02-RA110 Pag. 19

COMPACT ROUTER ADSL

RFC1483 and sends it through an ATM PVC (Permanent Virtual Circuit) to the Internet Service Provider's (ISP) DSLAM (digital access multiplexer). Please refer to RFC 2364 for more information on PPPoA. Refer to RFC 1661 for more information on PPP.

4.2.4 RFC 1483

RFC 1483 describes two methods for Multiprotocol Encapsulation over ATM Adaptation Layer 5 (AAL5). The first method allows multiplexing of multiple protocols over a single ATM virtual circuit (LLC-based multiplexing) and the second method assumes that each protocol is carried over a separate ATM virtual circuit (VC-based multiplexing). Please refer to the RFC for more detailed information.

4.3 Multiplexing

There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the multiplexing method required by your ISP.

4.3.1 VC-based Multiplexing

In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit; for example, VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of large numbers of ATM VCs is fast and economical.

4.3.2 LLC-based Multiplexing

In this case one VC carries multiple protocols with protocol identifying information being contained in each packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.

4.4 VPI and VCI

Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers assigned to you. The valid range for the VPI is 0 to 255 and for the VCI is 32 to 65535 (0 to 31 is reserved for local management of ATM traffic). Please see the appendix for more information.

Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP addresses and the subnet mask. If the ISP did not explicitly give you an IP network number, then most likely you have a single user account and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the Network Address Translation (NAT) feature of the ADSL Router. The Internet Assigned Number Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other number unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first three numbers specify the network number while the last number identifies an individual computer on that network. Once you have decided on the network number, pick an IP address that is easy to remember, for instance, 192.168.1.254, for the ADSL Router, 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. The ADSL Router 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 ADSL Router unless you are instructed to do otherwise.

4.7 IP Address Assignment

A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a different one each time. The Single User Account feature can be enabled or disabled if you have either a dynamic or static IP. However the encapsulation method assigned influences your choices for IP address and ENET ENCAP Gateway.

A02-RA110 Pag. 22

COMPACT ROUTER ADSL

4.7.1 IP Assignment with PPPoA or PPPoE Encapsulation

If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable (N/A). If you have a static IP, then you only need to fill in the IP Address field and not the ENET ENCAP Gateway field.

4.7.2 IP Assignment with RFC 1483 Encapsulation

In this case the IP Address Assignment must be static with the same requirements for the IP Address and ENET ENCAP Gateway fields as stated above.

4.7.3 IP Assignment with ENET ENCAP Encapsulation

In this case you can have either a static or dynamic IP. For a static IP you must fill in all the IP Address and ENET ENCAP Gateway fields as supplied by your ISP. However for a dynamic IP, the ADSL Router acts as a DHCP client on the WAN port and so the IP Address and ENET ENCAP Gateway fields are not applicable (N/A) as the DHCP server assigns them to the ADSL Router.

4.7.4 Private IP Addresses

Every machine on the Internet must have a unique address. If your networks are isolated from the Internet, for example, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks:

10.0.0.0 - 10.255.255.255; 172.16.0.0 - 172.31.255.255; 192.168.0.0 -

192.168.255.255

You 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.

4.8 Nailed-Up Connection (PPP)

A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand. The ADSL Router does two things when you specify a nailed-up connection. The first is that idle timeout is disabled. The second is that the ADSL Router will try to bring up the connection when turned on and whenever the connection is down. A nailed-up connection can be very expensive for obvious reasons.

A02-RA110 Pag. 23

COMPACT ROUTER ADSL

Do not specify a nailed-up connection unless your telephone company offers flatrate service or you need a constant connection and the cost is of no concern.

4.9 NAT

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network.

CHAPTER 5: LAN Setup

This chapter describes how to configure LAN settings.

5.1 LAN Overview

A Local Area Network (LAN) is a shared communication system to which many computers are attached. A LAN is a computer network limited to the immediate area, usually the same building or floor of a building. The LAN screens can help you configure a LAN DHCP server and manage IP addresses.

5.1.1 LANs, WANs and the ADSL Router

The actual physical connection determines whether the ADSL Router ports are LAN or WAN ports. There are two separate IP networks, one inside, the LAN network; the other outside: the WAN network as shown next:

A02-RA110 Pag. 34

COMPACT ROUTER ADSL

5.2 DNS Server Address

DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, for example, the IP address of www.atlantis-land.com is 204.217.0.2. 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 in DHCP Setup, otherwise, leave them blank. Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the DNS servers are conveyed through IPCP negotiation. The ADSL Router supports the IPCP DNS server extensions through the DNS proxy feature. If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, for instance, left as 0.0.0.0, the ADSL Router tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the ADSL Router, the ADSL Router forwards the query to the real DNS server learned through IPCP and relays the response back to the computer. Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you explicit DNS servers, make sure that you enter their IP addresses in the DHCP Setup menu. This way, the ADSL Router can pass the DNS servers to the computers and the computers can query the DNS server directly without the ADSL Router’s intervention.

5.3 DNS Server Address Assignment

Use DNS (Domain Name System) to map a domain name to its corresponding IP address and vice versa. The DNS server is extremely important because without it, you must know the IP address of a computer before you can access it. There are two ways that an ISP disseminates the DNS server addresses.

1. The ISP tells you the DNS server addresses, usually in the form of an

information sheet, when you sign up. If your ISP gives you DNS server addresses, enter them in the DNS Server fields in DHCP Setup.

2. Leave the DNS Server fields in DHCP Setup blank (for example 0.0.0.0). The

ADSL Router acts as a DNS proxy when this field is blank.

A02-RA110 Pag. 35

COMPACT ROUTER ADSL

5.4 LAN TCP/IP

The ADSL Router has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that support DHCP client capability.

5.4.1 Factory LAN Defaults

The LAN parameters of the ADSL Router are preset in the factory with the following values: IP address of 192.168.1.254 with subnet mask of 255.255.255.0 (24 bits) DHCP server enabled with 100 client IP addresses starting from 192.168.1.100. These parameters should work for the majority of installations. If your ISP gives you explicit DNS server address(es), read the embedded web configurator help regarding what fields need to be configured.

5.4.2 IP Address and Subnet Mask

Refer to the IP Address and Subnet Mask section in the Wizard Setup chapter for this information.

5.4.3 RIP Setup

RIP (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:

1. Both - the ADSL Router will broadcast its routing table periodically and

incorporate the RIP information that it receives.

2. In Only - the ADSL Router will not send any RIP packets but will accept all RIP

packets received.

3. Out Only - the ADSL Router will send out RIP packets but will not accept any

RIP packets received.

4. None - the ADSL Router 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 ADSL Router sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology. Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses subnet broadcasting while RIP-2M uses multicasting.

A02-RA110 Pag. 36

COMPACT ROUTER ADSL

5.4.4 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender - 1 recipient) or Broadcast (1 sender - everybody on the network). Multicast delivers IP packets to a group of hosts on the network - not everybody and not just 1. IGMP (Internet Group Multicast Protocol) is a network-layer protocol used to establish membership in a Multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to 239.255.255.255. The address

224.0.0.0 is not assigned to any group and is used by IP multicast computers.

The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts (including gateways). All hosts must join the

224.0.0.1 group in order to participate in IGMP. The address 224.0.0.2 is assigned

to the multicast routers group. The ADSL Router supports both IGMP version 1 (IGMP-v1) and IGMP version 2 (IGMP-v2). At start up, the ADSL Router queries all directly connected networks to gather group membership. After that, the ADSL Router periodically updates this information. IP multicasting can be enabled/disabled on the ADSL Router LAN and/or WAN interfaces in the web configurator (LAN; WAN). Select None to disable IP multicasting on these interfaces.

CHAPTER 6: WAN Setup

This chapter describes how to configure WAN settings.

6.1 WAN Overview

A WAN (Wide Area Network) is an outside connection to another network or the Internet. See the Wizard Setup chapter for more information on the fields in the WAN screens.

6.2 PPPoE Encapsulation

The ADSL Router supports PPPoE (Point-to-Point Protocol over Ethernet). PPPoE is an IETF Draft standard (RFC 2516) specifying how a personal computer (PC) interacts with a broadband modem (DSL, cable, wireless, etc.) connection. The PPPoE option is for a dial-up connection using PPPoE. For the service provider, PPPoE offers an access and authentication method that works with existing access control systems (for example Radius). PPPoE provides a login and authentication method that the existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or procedures for Windows users. One of the benefits of PPPoE is the ability to let you access one of multiple network services, a function known as dynamic service selection. This enables the service provider to easily create and offer new IP services for individuals. Operationally, PPPoE saves significant effort for both you and the ISP or carrier, as it requires no specific configuration of the broadband modem at the customer site. By implementing PPPoE directly on the ADSL Router (rather than individual computers), the computers on the LAN do not need PPPoE software installed, since the ADSL Router does that part of the task. Furthermore, with NAT, all of the LANs’ computers will have access.

6.3 PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a remote client to a private server, creating a Virtual Private Network (VPN) using TCP/IP-based networks. PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the Internet.

A02-RA110 Pag. 40

COMPACT ROUTER ADSL

6.4 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the subscriber to regulate the average rate and “burstiness” or fluctuation of data transmission over an ATM network. This agreement helps eliminate congestion, which is important for transmission of real time data such as audio and video connections. Peak Cell Rate (PCR) is the maximum rate at which the sender can send cells. This parameter may be lower (but not higher) than the maximum line speed. 1 ATM cell is 53 bytes (424 bits), so a maximum speed of 832 Kbps gives a maximum PCR of 1962 cells/sec. This rate is not guaranteed because it is dependent on the line speed. Sustained Cell Rate (SCR) is the mean cell rate of a bursty, on-off traffic source that can be sent at the peak rate, and a parameter for burst-type traffic. SCR may not be greater than the PCR; the system default is 0 cells/sec. Maximum Burst Size (MBS) is the maximum number of cells that can be sent at the PCR. After MBS is reached, cell rates fall below SCR until cell rate averages to the SCR again. At this time, more cells (up to the MBS) can be sent at the PCR again.The following figure illustrates the relationship between PCR, SCR and MBS.

CHAPTER 7: Network Address Translation (NAT)

This chapter discusses how to configure NAT on the ADSL Router.

7.1 NAT Overview

7.1.1 NAT Definitions

Inside/outside denotes where a host is located relative to the ADSL Router, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Global/local denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the global address refers to the IP address of the host when the same packet is traveling in the WAN side. Note that inside/outside refers to the location of a host, while global/local refers to the IP address of a host used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in a packet when the packet is still in the local network, while an inside global address (IGA) is the IP address of the same inside host when the packet is on the WAN side. The following table summarizes this information.

In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside local address) to another (the inside global address) before forwarding the packet to the WAN side. When the response comes back, NAT translates the destination address (the inside global address) back to the inside local address before forwarding it to the original inside host. Note that the IP address (either local or global) of an outside host is never changed. The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In addition, you can designate servers, for example, a web server and a telnet server, on your local network and make them accessible to the outside world. With no servers defined, the ADSL Router filters out all incoming inquiries, thus preventing intruders from probing your network. For more information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).

7.1.3 How NAT Works

Each packet has two addresses – a source address and a destination address. For outgoing packets, the ILA (Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones required for communication with hosts on other networks. It replaces the original IP source address (and TCP or UDP source port numbers for Many-to-One and Many-to-Many Overload NAT mapping) in each packet and then forwards it to the Internet. The ADSL Router keeps track of the original addresses and port numbers so incoming reply packets can have their original values restored. The following figure illustrates this.

7.1.4 NAT Application

The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using IP Alias) behind the ADSL Router can communicate with three distinct WAN networks. More examples follow at the end of this chapter.

7.1.5 NAT Mapping Types

NAT supports five types of IP/port mapping. They are:

1. One to One: In One-to-One mode, the ADSL Router maps one local IP address to one global IP address.

2. Many to One: In Many-to-One mode, the ADSL Router maps multiple local IP addresses to one global IP address.

3. Many to Many Overload: In Many-to-Many Overload mode, the ADSL Router maps the multiple local IP addresses to shared global IP addresses.

4. Many-to-Many No Overload: In Many-to-Many No Overload mode, the ADSL Router maps each local IP address to a unique global IP address.

5. Server: This type allows you to specify inside servers of different services behind the NAT to be accessible to the outside world. The following table summarizes these types.

Type IP Mapping

One-to-One ILA1 IGA1 Many-to-One (SUA/PAT) ILA1 IGA1

ILA2 IGA1 …

Many-to-Many Overload ILA1 IGA1

ILA2 IGA2 ILA3 IGA1 ILA4 IGA2 …

Many-to-Many No Overload ILA1 IGA1

ILA2 IGA2 ILA3 IGA3 …

Server Server 1 IP IGA1

Server 2 IP IGA1 Server 3 IP IGA1

7.2 SUA (Single User Account) Versus NAT

SUA (Single User Account) is a implementation of a subset of NAT that supports two types of mapping, Many-to-One and Server. The ADSL Router also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN IP addresses of clients or servers using mapping types as outlined in

A02-RA110 Pag. 49

COMPACT ROUTER ADSL

7.3 SUA Server

A SUA server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you can make visible to the outside world even though SUA makes your whole inside network appear as a single computer to the outside world. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. You can allocate a server IP address that corresponds to a port or a range of ports. Many residential broadband ISP accounts do not allow you to run any server processes (such as a Web or FTP server) from your location. Your ISP may periodically check for servers and may suspend your account if it discovers any active services at your location. If you are unsure, refer to your ISP. Default Server IP Address In addition to the servers for specified services, NAT supports a default server IP address. A default server receives packets from ports that are not specified in this screen.

7.3.1 Port Forwarding: Services and Port Numbers

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. Use the SUA Server page to forward incoming service requests to the server(s) on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on port 21. In some cases, such as for unknown services or where one server can support more than one service (for example both FTP and web service), it might be better to specify a range of port numbers. In addition to the servers for specified services, NAT supports a default server. A service request that does not have a server explicitly designated for it is forwarded to the default server. If the default is not defined, the service request is simply discarded. The most often used port numbers are shown in the following table. Please refer to RFC 1700 for further information about port numbers.

7.6 Configuring Address Mapping

Ordering your rules is important because the ADSL Router applies the rules in the order that you specify. When a rule matches the current packet, the ADSL Router takes the corresponding action and the remaining rules are ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed up by that number of empty rules. For example, if you have already configured rules 1 to 6 in your current set and now you configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9. Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so old rules 5, 6 and 7 become new rules 4, 5 and 6.

CHAPTER 9: Dynamic DNS Setup

This chapter discusses how to configure the ADSL Router to use Dynamic DNS.

9.1 Dynamic DNS

Dynamic DNS allows you to update your current dynamic IP address with one or many dynamic DNS services so that anyone can contact you (in NetMeeting, CUSeeMe, etc.). You can also access your FTP server or Web site on your own computer using a DNS-like address (for instance myhost.dhs.org, where myhost is a name of your choice) that will never change instead of using an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you even if they don't know your IP address. First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name. The Dynamic DNS service provider will give you a password or key.

9.1.1 DYNDNS Wildcard

Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example, www.yourhost.dyndns.org and still reach your hostname.

CHAPTER 11: Remote Management Configuration

This chapter provides information on configuring remote management. Remote management is not available on all models

11.1 Remote Management Overview

Remote management allows you to determine which services/protocols can access which ADSL Router interface (if any) from which computers. You may manage the ADSL Router from a remote location via:

 Internet (WAN only)  ALL (LAN and WAN)  LAN only  Neither (Disable)

To disable remote management of a service, select Disable in the corresponding Server Access field.

11.1.1 Remote Management Limitations

Remote management over LAN or WAN will not work when:

 A filter is applied to block a Telnet, FTP or Web service. 

You have disabled that service in one of the remote management screens.

 The IP address in the Secured Client IP field does not match the client IP

address. If it does not



There is an console session running.

 There is already another remote management session of the same type (web,

FTP or Telnet) running. You may only have one remote management session of the same type running at one time.

 There is a web remote management session running with a Telnet session. A

Telnet session will be disconnected if you begin a web session; it will not begin if there already is a web session.

11.1.2 Remote Management and NAT

When NAT is enabled:



Use the ADSL Router’s WAN IP address when configuring from the WAN.

 Use the ADSL Router’s LAN IP address when configuring from the LAN.
