xx Preface
What is DSL?
DSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted-pair wire that runs between the local telephone company switching offices and most homes and offices. While the wire itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above 4,000 Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to improve access to the Web - hence DSL technologies.
There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for Internet users because more information is usually downloaded than uploaded. For example, a simple button click in a web browser can start an extended download that includes graphics and text.
As data rates increase, the carrying distance decreases. That means that users who are beyond a certain distance from the telephone company’s central office may not be able to obtain the higher speeds.
A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no dialing required.
What is ADSL?
It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream data rate. As mentioned, this works well for a typical Internet session in which more information is downloaded, for example, from Web servers, than is uploaded. ADSL operates in a frequency range that is above the frequency range of voice services, so the two systems can operate over the same cable.

Prestige 650R-31/33 ADSL Router
Chapter 1
Getting To Know Your Prestige
This chapter describes the key features and applications of your Prestige.
1.1 Prestige 650 ADSL Internet Access Router
Your Prestige integrates a high-speed 10/100Mbps auto-negotiating LAN interface and one high-speed
ADSL port into a single package. The Prestige is ideal for high-speed Internet browsing and making LAN-
to-LAN connections to remote networks.
1.2 Features of the Prestige
Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.
High Speed Internet Access
Your Prestige ADSL router can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 832 Kbps. Prestige with ADSL over POTS also supports rate management.
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
Prestige 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.
Getting To Know Your Prestige 1-1
NAT for Single-IP-address Internet Access
The Prestige's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a
single IP account. NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.
10/100M Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the Prestige 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
Your Prestige supports up to 8 PVC’s.
ADSL Transmission Rate 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)).
♦ TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
♦ ATM Forum UNI 3.1/4.0 PVC.
♦ Supports up to 8 PVCs (UBR, CBR, VBR).
♦ Multiple Protocols over AAL5 (RFC 1483).

1-2 Getting To Know Your Prestige
Prestige 650R-31/33 ADSL Router
♦ PPP over Ethernet over AAL5 (RFC 2516).
♦ RFC 1661.
♦ PPP over PAP (RFC 1334).
♦ PPP over CHAP (RFC 1994).
• Protocol Support
♦ DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain
the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige 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 Prestige 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 Prestige supports three logical LAN interfaces via its single physical Ethernet
interface with the Prestige 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.
♦ PPP (Point-to-Point Protocol) link layer protocol.
♦ Transparently bridging for unsupported network layer protocols.
♦ RIP I/RIP II
♦ IGMP Proxy
♦ ICMP support
Getting To Know Your Prestige 1-3

1.3 Applications for the Prestige
1.3.1 Internet Access
The Prestige is the ideal high-speed Internet access solution. Your Prestige 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. A typical Internet Access application is shown below.
Figure 1-1 Internet Access Application
Internet Single User Account
For a SOHO (Small Office/Home Office) environment, your Prestige offers the Single User Account (SUA)
feature that allows multiple users on the LAN (Local Area Network) to access the Internet concurrently for
the cost of a single IP address.
1.3.2 LAN to LAN Application
You can use the Prestige to connect two geographically dispersed networks over the ADSL line. A typical
LAN-to-LAN application for your Prestige is shown as follows.

Figure 2-2 Prestige Rear Panel and Connections
2.2.1 DSL Port
Connect the Prestige directly to the wall jack using the included DSL cable. Connect a microfilter(s) between the wall jack and your telephone(s). A microfilter acts as low-pass filter (voice transmission takes place in the 0 to 4KHz bandwidth) and is an optional purchase.
Hardware Installation and Initial Setup 2-3
Prestige 650R-31/33 ADSL Router
2.2.2 Console Port
Use terminal emulator software on a computer for configuring your Prestige via console port. Connect the 7-pin end of the supplied console cable to the console port of the Prestige and the 9-pin female end to a serial port (COM1, COM2 or other COM port) of your computer.
2.2.3 LAN 10/100M Port
Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-11 connectors (POTS) that look like a bigger telephone plug with 8 pins. Use the crossover cable to connect your Prestige to a computer directly or use a straight-through Ethernet cable to connect to an external hub, then connect one end of the straight-through cable from the hub to the NIC on the computer.
When the Prestige is on and properly connected to a computer or a hub, the
corresponding LAN LED on the front panel turns on.
2.2.4 Power Port
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.
To avoid damage to the Prestige, use the correct power adapter. Refer to the
Power Adapter Specification Appendix for this information.
2.2.5 Reset Button
Refer to section 2.8 for information on the RESET button.
2.3 Additional Installation Requirements
A computer with an Ethernet 10Base-T/100Base-T NIC (Network Interface Card). A computer equipped with communications software (for example, Hyper Terminal in Windows 95)
configured to the following parameters:
VT100 terminal emulation.
9600 baud rate.
Parity set to none, 8 data bits, 1 stop bit.
Flow control set to none.
After the Prestige has been successfully connected to your network, you can make future changes to the configuration via Telnet or the embedded web configurator.
2-4 Hardware Installation and Initial Setup
Prestige 650R-31/33 ADSL Router
2.4 Prestige with POTS
Sections 2.4.1 and 2.4.2 relate to people who use their Prestige with ADSL over POTS (analog telephone service) only.
2.4.1 Connecting a POTS Splitter
This is for the Prestige that follows the Full Rate (G.dmt) standard only. One major difference between ADSL and dial-up modems is the optional telephone splitter. This device keeps the telephone and ADSL signals separated, giving them the capability to provide simultaneous Internet access and telephone service on the same line. Splitters also eliminate the destructive interference conditions caused by telephone sets. The purchase of a POTS splitter is optional.
Noise generated from a telephone in the same frequency range, as the ADSL signal can be disruptive to the ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the strength of the ADSL signal. When a POTS splitter is installed at the entry point, where the line comes into the home, it will filter the telephone signals before combining the ADSL and telephone signals transmitted and received. The issues of noise and impedance are eliminated with a single POTS splitter installation.
A telephone splitter is easy to install as shown in the following figure.
Figure 2-3 Connecting a POTS Splitter
Step 1. Connect the side labeled “Phone” to your telephone.
Step 2. Connect the side labeled “Modem” to your Prestige.
Step 3. Connect the side labeled “Line” to the telephone wall jack.
Hardware Installation and Initial Setup 2-5
2.4.2 Telephone Microfilters
Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter, for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice transmissions. The purchase of a telephone microfilter is optional.
Step 1. Connect a phone cable from the wall jack to the single jack end of the Y- Connector.
Step 2. Connect a cable from the double jack end of the Y-Connector to the “wall side” of the
microfilter.
Step 3. Connect another cable from the double jack end of the Y-Connector to the Prestige.
Step 4. Connect the “phone side” of the microfilter to your telephone as shown in the following figure.
Figure 2-4 Connecting a Microfilter
2.5 Prestige With ISDN
This section relates to people who use their Prestige with ADSL over ISDN (digital telephone service) only. The following is an example installation for the Prestige with ISDN.
2-6 Hardware Installation and Initial Setup

Figure 2-5 Prestige with ADSL over ISDN
2.6 Turning On Your Prestige
At this point, you should have connected the DSL, LAN 10/100M, console and power ports to the appropriate devices. Make sure the power adapter is plugged into an appropriate power source and the power switch (located on the back of your Prestige) is “on” (or pressed).
2.7 Configuring Your Prestige For Internet Access
Configure your Prestige for Internet access using:
Web Configurator (refer to the Read Me First)
SMT (System Management Terminal). Access the SMT via:
o LAN or WAN using Telnet
o Console port using terminal emulation software
The remainder of this user’s guide shows you how to configure the Prestige for Internet access using SMT screens through the console port. There are also some sections in this guide that also focus on using Telnet to configure the Prestige.

2.8 Resetting the Prestige
If you forget your password or cannot access the Prestige, you will need to reload the factory-default configuration file. Uploading this configuration file replaces the current configuration file with the factory­default configuration file. This means that you will lose all configurations that you had previously and the speed of the console port will be reset to the default of 9600bps with 8 data bit, no parity, one stop bit and flow control set to none. The password will be reset to “1234” and the LAN IP address to 192.168.1.1.
To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a folder. Turn the Prestige off and then on to begin a session. When you turn on the Prestige again you will

see the initial screen. When you see the message “Press any key to enter Debug Mode within 3 seconds” press any key to enter debug mode.
To upload the configuration file, do the following:
1. Type atlc after the Enter Debug Mode message.
2. Wait for the Starting XMODEM upload message before activating XMODEM upload on your terminal.
3. After a successful firmware upload, type atgo to restart the Prestige.
The Prestige is now reinitialized with a default configuration file including the default password of “1234”.
2.8.1 Methods of Restoring Factory-Defaults
You can erase the current configuration and restore factory defaults in three ways:
1. Use the web configurator (see the web configurator HTML help).
2. Upload the default configuration file via the console port as described above. See later in this User’s Guide for more information on how to transfer the configuration file to your Prestige using the SMT menus.
3. Use the RESET button on the rear panel of the Prestige (see the next section).
2.8.2 Procedure To Use The Reset Button
1. Turn your Prestige off and then on. Make sure the SYS led is on (not blinking).
2. Press the RESET button for five seconds and then release it. If the SYS LED begins to blink, the defaults have been restored and the Prestige restarts.

Chapter 3
Internet Access
This chapter shows you how to configure the LAN and WAN of your Prestige for Internet access.
3.1 Factory Ethernet Defaults
The Ethernet parameters of the Prestige are preset in the factory with the following values:
1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If the parameters are satisfactory, you can skip to TCP/IP Ethernet Setup and DHCP to enter the DNS server address(es) if your ISP gives you explicit DNS server address(es). If you wish to change the factory defaults or to learn more about TCP/IP, please read on.
3.2 LANs and WANs
A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside connection to another network or the Internet.
3.2.1 LANs, WANs and the Prestige
The actual physical connection determines whether the Prestige 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:
Internet Access 3-1
Figure 3-1 LAN & WAN IPs
3.3 TCP/IP Parameters
3.3.1 IP Address and Subnet Mask
Like houses on a street that share a common street name, the computers on a LAN share one common network number.
Where you obtain your network number depends on your particular situation. If the ISP or your network administrator assigns you a block of registered IP 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 (ignoring the trailing zero) and you must enable the Single User Account feature of the Prestige. 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.
The subnet mask specifies the network number portion of an IP address. Your Prestige 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 Prestige unless you are instructed to do otherwise.
3-2 Internet Access
Prestige 650R-31/33 ADSL Router
3.3.2 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.
Note: Regardless of your particular situation, do not create an arbitrary IP
address; always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
3.3.3 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 Prestige will broadcast its routing table periodically and incorporate the RIP information
that it receives.
2. In Only - the Prestige will not send any RIP packets but will accept all RIP packets received.
3. Out Only - the Prestige will send out RIP packets but will not accept any RIP packets received.
4. None - the Prestige 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 Prestige 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.
Internet Access 3-3
3.3.4 DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to Windows 95, Windows NT and other systems that support the DHCP client. The Prestige can also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to the clients.
IP Pool Setup
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for the client machines. This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself which has a default IP of 192.168.1.1) for other server machines, for example, server for mail, FTP, telnet, web, etc., that you may have.
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.zyxel.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 does give 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 Prestige 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 Prestige tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS query to the Prestige, the Prestige 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 Prestige can pass the DNS servers to the computers and the computers can query the DNS server directly without the Prestige’s intervention.
3-4 Internet Access
Prestige 650R-31/33 ADSL Router
3.4 IP 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 is a third way to deliver IP packets to a group of hosts on the network - not everybody.
IGMP (Internet Group Multicast Protocol) is a session-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 Prestige supports both IGMP version 1 (IGMP-v1) and version 2 (IGMP-v2). At start up, the Prestige queries all directly connected networks to gather group membership. After that, the Prestige periodically updates this information. IP Multicasting can be enabled/disabled on the Prestige LAN and/or WAN interfaces using menus 3.2 (LAN) and 11.3 (WAN). Select None to disable IP Multicasting on these interfaces.
3.5 IP Policies
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. Policy-based routing is applied to incoming packets on a per interface basis, prior to the normal routing. Create policies using SMT menu 25 (see IP Policy Routing) and apply them on the Prestige LAN and/or WAN interfaces using menus 3.2 (LAN) and 11.3 (WAN).
3.6 IP Alias
IP Alias allows you to partition a physical network into different logical networks over the same Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with the Prestige itself as the gateway for each LAN network.

3.9 VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers supplied by your telephone company. 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 Appendices for more information.
3.10 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.
3.10.1 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.
3.10.2 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
3-10 Internet Access
Prestige 650R-31/33 ADSL Router
is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on the number of simultaneous VCs.
3.11 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following methods.
3.11.1 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 menu 4 and in the Rem IP Addr field in menu 11.1. You can get this information from your ISP.
3.11.2 PPP over Ethernet
PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP. The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an ATM PVC (Permanent Virtual Circuit) which connects to a xDSL 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 Appendices.
3.11.3 PPPoA
Please refer to RFC 2364 for more information on PPP over ATM Adaptation Layer 5 (AAL5). Refer to RFC 1661 for more information on PPP.
3.11.4 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.
3.12 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
Internet Access 3-11
static IP. However the encapsulation method assigned influences your choices for IP Address and ENET ENCAP Gateway.
3.12.1 Using 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.
3.12.2 Using 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.
3.12.3 Using 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 Prestige 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 they are assigned to the Prestige by the DHCP server.
3.13 Internet Access Configuration
Menu 4 allows you to enter the Internet Access information in one screen. Menu 4 is actually a simplified setup for one of the remote nodes that you can access in menu 11. Before you configure your Prestige for Internet access, you need to collect your Internet account information from your ISP and telephone company.
Use the following table to record your Internet Account Information. Note that if you are using PPPoA or PPPoE encapsulation, then the only ISP information you need is a login name and password. You only need to know the Ethernet Encapsulation Gateway IP address if you are using ENET ENCAP encapsulation.

3.13.1 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.
If the PCR, SCR or MBS is set to the default of “0”, the system will assign a
maximum value that correlates to your upstream line rate.
The following figure illustrates the relationship between PCR, SCR and MBS.

Chapter 4
Remote Node Configuration
This chapter covers the parameters that are protocol-independent. Protocol-dependent
configuration (TCP/IP and Bridging) is covered in the following chapters.
A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across a WAN connection. When you use menu 4 to set up Internet
access, you are configuring one of the remote nodes.
4.1 Remote Node Setup
This section describes the protocol-independent parameters for a remote node.
4.1.1 Remote Node Profile
To configure a remote node, follow these steps:
Step 1. From the main menu, enter 11 to display Menu 11 - Remote Node Setup.
Step 2. When menu 11 appears, as shown in the following figure, type the number of the remote node
that you want to configure.

4.1.2 Encapsulation and Multiplexing Scenarios
For Internet access you should use the encapsulation and multiplexing methods used by your ISP. For
LAN-to-LAN applications, for example, between a branch office and corporate headquarters, prior
agreement on methods is necessary because encapsulation and multiplexing cannot be automatically
determined. What method(s) you use depends on how many VCs you have and how many different network
protocols you need. The extra overhead that ENET ENCAP encapsulation entails makes it a poor choice in
a LAN-to-LAN application. Here are some examples of more suitable combinations in such an application.
Scenario 1. One VC, Multiple Protocols
PPPoA (RFC-2364) encapsulation with VC-based multiplexing is the best combination because no extra
protocol identifying headers are needed. The PPPoA protocol already contains this information.
Scenario 2. One VC, One Protocol (IP)
Selecting RFC-1483 encapsulation with VC-based multiplexing requires the least amount of overhead (0
octets). However, if there is a potential need for multiple protocol support in the future, it may be safer to
select PPPoA encapsulation instead of RFC-1483, so you do not need to reconfigure either computer later.
Scenario 3. Multiple VCs
If you have an equal number (or more) of VCs than the number of protocols, then select RFC-1483
encapsulation and VC-based multiplexing.
4-2 Remote Node Configuration
Nailed-Up Connection (PPPoA/PPPoE)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand.
The Prestige does two things when you specify a nailed-up connection.
The first is that idle timeout is disabled.
The second is that the Prestige 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. Do not specify a nailed-up connection
unless your telephone company offers flat-rate service or you need a constant connection and the cost is of
no concern.

4.1.3 Outgoing Authentication Protocol
For obvious reasons, you should employ the strongest authentication protocol possible. However, some
vendors’ implementation includes specific authentication protocol in the user profile. It will disconnect if
the negotiated protocol is different from that in the user profile, even when the negotiated protocol is
stronger than specified. If the peer disconnects right after a successful authentication, make sure that you
specify the correct authentication protocol when connecting to such an implementation.

5.1.2 IP Static Route Setup
Static routes tell the Prestige routing information that it cannot learn automatically through other means.
This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is
directly connected to a remote node.
Remote Node TCP/IP Configuration 5-5
Each remote node specifies only the network to which the gateway is directly connected and the Prestige
has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the
following figure through remote node Router 1. However, the Prestige is unable to route a packet to
network N3 because it does not know that there is a route through remote node Router 1 (via Router 2). The
static routes allow you to tell the Prestige about the networks beyond the remote nodes.

FIELD DESCRIPTION
Route # This is the index number of the static route that you chose in menu 12.1.
Route Name Type a descriptive name for this route. This is for identification purpose only.
Active This field allows you to activate/deactivate this static route.
Destination IP Address This parameter specifies the IP network address of the final destination.
Routing is always based on network number. If you need to specify a route to a single host, use a subnet mask of 255.255.255.255 in the subnet mask field to force the network number to be identical to the host ID.
Remote Node TCP/IP Configuration 5-7
Table 5-3 Edit IP Static Route Menu Fields
FIELD DESCRIPTION
IP Subnet Mask Type the subnet mask for this destination. Follow the discussion on IP Subnet
Mask in this manual.
Gateway IP Address Type the IP address of the gateway. The gateway is an immediate neighbor of
your Prestige that will forward the packet to the destination. On the LAN, the gateway must be a router on the same segment as your Prestige; over WAN, the gateway must be the IP address of one of the remote nodes.
Metric Metric represents the “cost” of transmission for routing purposes. IP routing
uses hop count as the measurement of cost, with a minimum of 1 for directly connected networks. Type a number that approximates the cost for this link. The number need not be precise, but it must be between 1 and 15. In practice, 2 or 3 is usually a good number.
Private This parameter determines if the Prestige will include the route to this remote
node in its RIP broadcasts. If set to Yes, this route is kept private and is not included in RIP broadcasts. If No, the route to this remote node will be propagated to other hosts through RIP broadcasts.

Bridging Setup
This chapter shows you how to configure the bridging parameters of your Prestige.
6.1 Bridging in General
Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while
routing does it on the network layer (IP) address. Bridging allows the Prestige to transport packets of
network layer protocols that it does not route, for example, SNA, from one network to another. The caveat
is that, compared to routing, bridging generates more traffic for the same network layer protocol, and it also
demands more CPU cycles and memory.
For efficiency reasons, do not turn on bridging unless you need to support protocols other than IP on your
network. For IP, enable the routing if you need it; do not bridge what the Prestige can route.
6.2 Bridge Ethernet Setup
Basically, all non-local packets are bridged to the WAN. Your Prestige does not support IPX.
6.2.1 Remote Node Bridging Setup
Follow the procedure in another section to configure the protocol-independent parameters in Menu 11.1 –
Remote Node Profile. For bridging-related parameters, you need to configure Menu 11.3 – Remote Node
Network Layer Options.
To setup Menu 11.3 – Remote Node Network Layer Options shown in the next figure, follow these steps:
Step 1. In menu 11.1, make sure the Bridge field is set to Yes.
Step 2. Move the cursor to the Edit IP/Bridge field, then press [SPACE BAR] to set the value to Yes
and press [ENTER] to edit Menu 11.3 – Remote Node Network Layer Options.

Network Address Translation (NAT)
This chapter discusses how to configure NAT on the Prestige.
7.1 Introduction
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.
7.1.1 NAT Definitions
Inside/outside denotes where a host is located relative to the Prestige, 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.
Table 7-1 NAT Definitions
TERM DESCRIPTION
Inside This refers to the host on the LAN.
Outside This refers to the host on the WAN.
Local This refers to the packet address (source or destination) as the packet travels on the LAN.
Global This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT 7-1
Prestige 650R-31/33 ADSL Router
NAT never changes the IP address (either local or global) of an outside host.
7.1.2 What NAT Does
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. Although you can make designated servers on the LAN
accessible to the outside world, it is strongly recommended that you attach those servers to the DMZ port
instead. If you do not define any servers (for Many-to-One and Many-to-Many Overload mapping – see
Table 7-2), NAT offers the additional benefit of firewall protection. With no servers defined, your Prestige
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 Prestige keeps track of the original addresses and port
numbers so incoming reply packets can have their original values restored. The following figure illustrates
this.
7-2 NAT
Figure 7-1 How NAT Works
7.1.4 NAT Application
The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using
IP Alias) behind the Prestige can communicate with three distinct WAN networks. More examples follow at
the end of this chapter.
NAT 7-3
Figure 7-2 NAT Application With IP Alias
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 Prestige maps one local IP address to one global IP address.
2. Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP
address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s Single User
Account feature that previous ZyXEL routers supported (the SUA Only option in today’s routers).
3. Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP
addresses to shared global IP addresses.
7-4 NAT
Prestige 650R-31/33 ADSL Router
4. Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige 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 although, it is highly recommended that you use the DMZ port for these
servers instead.
Port numbers do not change for One-to-One and Many-to-Many No Overload NAT
mapping types.
The following table summarizes these types.

7.2 Using NAT
7.2.1 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two types of
mapping, Many-to-One and Server. See section 7.3.1 for a detailed description of the NAT set for SUA.
The Prestige 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 Table 7-2.
1. Choose SUA Only if you have just one public WAN IP address for your Prestige.
2. Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.
7.2.2 Applying NAT
You apply NAT via menus 4 or 11.3 as displayed next. The next figure shows you how to apply NAT for
Internet access in menu 4. Enter 4 from the main menu to go to Menu 4 - Internet Access Setup.

Ordering Your Rules
Ordering your rules is important because the Prestige applies the rules in the order that you specify. When a
rule matches the current packet, the Prestige 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.

7.4 NAT Server Sets – Port Forwarding
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you
can make visible to the outside world even though NAT makes your whole inside network appear as a
single machine to the outside world.
Use Menu 15 – NAT Setup 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.
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.
The most often used port numbers are shown in the following table. Please refer to RFC 1700 for further
information about port numbers. Please also refer to the included disk for more examples and details on
NAT.
