xxii Preface
Prestige 642R Series ADSL Router
What is DSL?
DSL (Digital Subscriber Line) 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, e.g., 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. What are the
advantages of ADSL from the point of view of the Network Service Provider (NSP) and the end user?
Advantages to the Network Service Provider (NSP)
1. ADSL enables telephone companies (telcos) to use the world's nearly 750 million existing copper wires
to deliver affordable high-speed remote access to the Internet, corporate networks and on-line services
over ordinary phone lines.
2. ADSL enables new applications that require real-time, interactive multimedia and broadcast-quality
video. Such applications include collaborative computing, video conferencing, distance learning and
video-on-demand.
3. The industry is rapidly converging on standards that will enable interoperability and ultimately make a
mass market possible.
4. ADSL empowers service providers to provide either a guaranteed sustained or adaptive rate, or best
effort service similar to analog modems.
¾ Nearly 300 times faster than 24.4 Kbps modems
¾ Over 100 times faster than 56 Kbps modems
¾ 70 times faster than 128 Kbps ISDN
5. Both residential and business properties around the world are already running out of spare lines on
existing installed telephone cables. ADSL provides service providers with the capability to use one line
to provide new data services while maintaining the telephone service on the same line, thus leveraging
the existing infrastructure.
What is DSL? xxiii
Prestige 642R Series ADSL Router
6. ADSL provides telcos with the ability to offer a private, secure channel of communications between
the consumer and the service provider.
7. Data travels along the customers own line, unlike cable telephone and modem services where the line is
shared with others
8. Because it is one customer's dedicated line, transmission speeds are not affected by other users going
on-line. With cable modems, transmission speeds drop significantly as more users go on-line
9. ADSL is "always on" and connected, just like a standard telephone. There is no time wasted dialing up
the service several times a day and waiting to be connected; ADSL is on standby, waiting ready for use
whenever your customer is ready.
10. Every major service provider has conducted trials and proven that the technology works. Today,
service providers are rolling out ADSL services worldwide, with widespread deployment expected. In
support of this market, a large number of major equipment vendors are shipping second and thirdgeneration products offering higher performance and lower costs.
11. ADSL-based networks are well suited for carrying ATM traffic, thus guaranteeing ADSL technology
for decades to come.
12. ADSL provides the communication bridge into the next century without adding new infrastructure,
costly outside plant additions and reinvestment.
Advantages to the End User
1. ADSL transforms plain old telephone lines into a high speed conduit for data, information,
entertainment and more. And while it is doing that, you can use your telephone for normal
conversations at the same time. This provides enormous advantages whether at home or at work.
2. ADSL provides affordable high-speed remote access to the Internet, corporate networks and on-line
services over ordinary phone lines.
¾ Nearly 300 times faster than 24.4 Kbps modems
¾ Over 100 times faster than 56 Kbps modems
¾ 70 times faster than 128 Kbps ISDN
For example, if there were no constraints of the Internet backbone or if fast servers were located in every
telephone central office, an ADSL modem could download the entire Encyclopedia Britannica to a user's
laptop in 16.6 minutes, compared to 6.4 days using a typical modem speed of 14,400 bps.
3. ADSL enables the use of real-time, interactive multimedia and broadcast-quality video for such new
services as collaborative computing, video conferencing, distance learning and video-on-demand.
4. ADSL gives you the ability to have both voice and data services in use simultaneously and all over one
phone line. Both residential and business properties around the world are already running out of spare
lines on existing installed telephone cables so effectively doubling your capacity in this way is a real
benefit.
5. ADSL provides a private, secure channel of communications between you and the service provider.
6. Your data travels along you own line, unlike cable telephone and modem services where the line is
shared with others.
7. Because it is your own dedicated line, transmission speeds are not affected by other users going online. With cable modems, transmission speeds drop significantly as more users go on-line.

Prestige 642R Series ADSL Router
Chapter 1
Getting to Know Your ADSL Internet Access
Router
This chapter describes the key features and applications of the Prestige 642
1.1 Prestige 642R Series 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 LANto-LAN connections to remote networks.
1.2 Features of the Prestige 642R
Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.
z High Speed Internet Access
The P642 ADSL router can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 640Kbps. The P642 also supports rate management; rate management allows ADSL
subscribers to select an Internet access speed that best suits their needs and budgets.
z 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 PCs on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual PCs.
z Transmission Rate Standards
1
♦ Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt(G.992.1); G.lite(G992.2))
♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt(G.992.1)) with line rate support of up to 8Mbps
downstream and 1024kbps upstream.
♦ G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream.
z 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.

Depends on firmware release version.
Getting to know your Prestige 1-1
Prestige 642R Series ADSL Router
z IP Multicast
Traditionally, IP packets are transmitted in two ways: unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to
support multicast groups. The latest version is version 2 (see RFC2236). Both versions 1 and 2 are
supported by the Prestige
z 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.
z 10/100M Fast Ethernet LAN Interface
The P642's 10/100M auto-negotiating LAN interface enables fast data transfer of either 10Mbps or
100Mbps in either half-duplex or full-duplex mode depending on your Ethernet network.
z Protocols Supported
TCP/IP (Transmission Control Protocol/Internet Protocol) network layer protocol.
PPP (Point-to-Point Protocol) link layer protocol.
SUA™ (Single User Account) and NAT (Network Address Translation).
z Multiple Protocol Support
♦ Novel IPX (Internetwork Packet eXchange) network layer protocol.
♦ Transparently bridging for unsupported network layer protocols.
z 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 the built-in DHCP
Server enabled by default. DHCP Relay allows the Prestige to act as a surrogate DHCP server where it
relays IP address assignment from the actual DHCP server to its clients.
z Multiple PVC (Permanent Virtual Circuits) Support
Your Prestige supports up to 8 PVC’s.
z Networking Compatibility
Your Prestige is compatible with the major ADSL DSLAM (Digital Subscriber Line Access Multiplexer)
providers, making configuration as simple as possible for you.
z Multiplexing
The Prestige 642R Series supports VC-based and LLC-based multiplexing.
z Encapsulation
The Prestige 642R Series supports PPP (RFC 2364 - PPP over ATM Adaptation Layer 5), RFC 1483
encapsulation over ATM, MAC encapsulated routing as well as PPP over Ethernet (RFC 2516).
1-2 Getting to know your Prestige
Prestige 642R Series ADSL Router
z NAT/SUA 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. SUA supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealAudio, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.
z Full Network Management
♦ SNMP (Simple Network Management Protocol) support.
♦ Accessing SMT (System Management Terminal) through a Telnet connection
♦ Windows-based PNC (Prestige Network Commander)
z PAP and CHAP Security
The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure since the password is scrambled prior to transmission.
However, PAP is readily available on more platforms.
z Filters
The Prestige's packet filtering functions allows added network security and management.
z Ease of Installation
Your Prestige is designed for quick, intuitive and easy installation.
z Housing
Your Prestige's all new compact, ventilated housing minimizes space requirements making it easy to
position anywhere in your busy office.
1.3 Applications for the Prestige 642R
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 (e.g., 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.

The ADSL LED is on when the Prestige is connected successfully to a DSLAM. The
LED blinks when data is being sent/received. The LED is off when the link is down.
2.2 Rear Panel and Connections of the Prestige 642R
The following figure shows the rear panel connectors of your Prestige:
Hardware Installation & Setup 2-1
Prestige 642R Series ADSL Router
Figure 2-2 Prestige 642R Series Rear Panel
Step 1: Connecting the ADSL Line
Connect the Prestige directly to the wall jack using the included ADSL cable. Connect a microfilter(s) (see
Figure 2-4 Connecting a Microfilter) between the wall jack and your telephone(s). The micro filters
act as low-pass filters (voice transmission takes place in the 0 to 4KHz bandwidth).
Step 2: Connecting a Workstation to the Prestige 10/100M LAN port
Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-45 connectors that
look like a bigger telephone plug with 8 pins. Use the crossover cable (red tag) to connect your Prestige 642
to a computer directly. Use a straight-through-Ethernet cable (white tag) to connect to an external hub, then
connect one end of the straight-through-Ethernet cable (white tag) from the hub to the NIC on the
workstation.
Step 3.
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.
Connecting the Power Adapter to your Prestige
Please note that the Power Switch is not available in all P642 models.
Step 4. Connecting the Console Port
For the initial configuration of your Prestige, you need to use terminal emulator software on a workstation
and connect it to the Prestige through the console port. Connect the 9-pin end of the console cable (9-pin to
25-pin console cable supplied) to the console port of the Prestige and the 25-pin end to a serial port (COM1,
COM2 or other COM port) of your workstation. You can use an extension RS-232 cable if the enclosed
one is too short.
2.3 Additional Installation Requirements
In addition to the contents of your package, there are other hardware and software requirements you need to
meet before you can install and use your Prestige. These requirements include:
z A computer with an Ethernet 10Base-T/100Base-T NIC (Network Interface Card).
z A computer equipped with communications software (for example, Hyper Terminal in Win95)
configured to the following parameters:
¾ VT100 terminal emulation.
¾ 9600 Baud rate.
¾ Parity set to None, 8 Data bits, 1 Stop bit.

After the Prestige has been successfully connected to your network, you can make future changes to the
configuration via Telnet.
2.4 Connecting a POTS Splitter
This is for the P642’s following the Full Rate (G.dmt) standard only. One major difference between ADSL
and dial-up modems is the need for a 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.

2.5 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.

Prestige 642R Series ADSL Router
Chapter 3
Internet Access
This chapter shows you how to configure the LAN as well as the 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 section 3.4 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 & 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:
Figure 3-1 LAN & WAN IPs
Internet Access 3-1
Prestige 642R Series ADSL Router
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 machines 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 workstation 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.
3.3.2 Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
e.g., 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,
3-2 Internet Access
Guidelines for Management of IP Address Space.
Prestige 642R Series ADSL Router
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 Both, the Prestige will
broadcast its routing table periodically and incorporate the RIP information that it receives; when set to
None, it 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 a 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. Multicasting can reduce the load on non-router
machines since they generally do not listen to the RIP multicast address and so will not receive the RIP
packets. However, if one router uses multicasting, then all routers on your network must use multicasting as
well.
By default, RIP direction is set to Both and the Version set to RIP-1.
3.3.4 DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (workstations) 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, e.g., 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,
e.g., 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
Internet Access 3-3
Prestige 642R Series ADSL Router
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, i.e., left as 0.0.0.0, the
Prestige tells the DHCP clients that it itself is the DNS server. When a workstation 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 workstation.
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 workstations and the workstations can query the DNS server directly
without the Prestige’s intervention.
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 the IP Policy Routing chapter in Part 3) 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 & VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
supplied by the telephone company. The valid range for the VPI is 1 to 255 and for the VCI is 32 to 65535 (1
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, e.g., VC1
carries IP, VC2 carries IPX, 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
is not practical to have a separate VC for each carried protocol, e.g., 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.
Internet Access 3-9
Prestige 642R Series ADSL Router
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 i.e., 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 PC 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 PPP
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
static IP. However the encapsulation method assigned influences your choices for IP Address and ENET
ENCAP Gateway.
3.12.1 Using PPP 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.
3-10 Internet Access
Prestige 642R Series ADSL Router
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 PPP 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.

3.14 Single User Account
Typically, if there are multiple users on the LAN wanting to concurrently access the Internet, you will have
to lease a block of legal, or globally unique, IP addresses from the ISP.
The Single User Account (SUA) feature allows you to have the same benefits as having multiple legal
addresses, but only pay for one IP address, thus saving significantly on the subscription fees. (Check with
your ISP before you enable this feature).
The IP address for the SUA can be either fixed or dynamically assigned by the ISP. In addition, you can
designate servers, e.g., a web server and a Telnet server, on your local network and make them accessible to
the outside world. If you do not define any server, SUA offers the additional benefit of firewall protection. If
no server is defined, all incoming inquiries will be filtered out by your Prestige, thus preventing intruders
from probing your network. Your Prestige accomplishes this address sharing by translating the internal LAN
IP addresses to a single address that is globally unique on the Internet. For more information on IP address
translation, refer to RFC 1631, The IP Network Address Translator (NAT).
3.14.1 Advantages of SUA
In summary:
z SUA is a cost-effective solution for small offices to access the Internet or other remote TCP/IP networks.
z SUA supports servers to be accessible to the outside world.
z SUA can provide firewall protection if you do not specify a server. All incoming inquiries will be
filtered out by your Prestige.
z UDP and TCP packets can be routed. In addition, partial ICMP, including echo and traceroute, is
supported.
3.14.2 Single User Account Configuration
The steps for configuring your Prestige for Single User Account are identical to the conventional Internet

3.15 Multiple Servers behind SUA
If you wish, you can make inside servers for different services, e.g., web or FTP, visible to the outside users,
even though SUA makes your whole inside network appear as a single machine to the outside world. A
service is identified by the port number, e.g., web service is on port 80 and FTP on port 21.
As an example, if you have a web server at 192.168.1.2 and an FTP server 192.168.1.3, then you need to
specify for port 80 (web) the server at IP address 192.168.1.2 and for port 21 (FTP) another at IP address
192.168.1.3.
Internet Access 3-15
Prestige 642R Series ADSL Router
Please note that a server can support more than one service, e.g., a server can provide both FTP and DNS
service, while another provides only web service. Also, since you need to specify the IP address of a server
in the Prestige, a server must have a fixed IP address and not be a DHCP client whose IP address potentially
changes each time it is powered on.
In addition to the servers for specific services, SUA 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 server is not
defined, the service request is simply discarded.
To make a server visible to the outside world, specify the port number of the service and the inside IP address
of the server in Menu 15 – SUA Server Setup.

Chapter 4
Remote Node Configuration
In this chapter, we discuss the parameters that are protocol independent.
The protocol-dependent configurations are covered in subsequent 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. Note that when you use Menu 4 to set up
Internet access, you are actually 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, select menu option 11 - Remote Node Setup.
Step 2. When Menu 11 appears, as shown in the following figure, enter the number of the remote node
that you wish 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, e.g., branch office and corporate headquarters, prior mutual agreement on
methods used is necessary because there is no mechanism to automatically determine encapsulation or
multiplexing. Selection of which encapsulation and multiplexing methods to use depends on how many
VCs you have and how many different network protocols you need. The extra overhead that PPP over
Ethernet (PPPoE) and ENET ENCAP encapsulation entail makes them 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
PPP (RFC-2364) encapsulation with VC-based multiplexing is the best combination because the extra
protocol identifying headers that LLC-based multiplexing uses is not needed. The PPP protocol already
contains this information.
Scenario 2. One VC, One Protocol (IP)
Select 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 PPP encapsulation instead of RFC-1483, so you do not need to reconfigure either machine when the
time comes.
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.
When Menu 11.1 – Remote Node Profile appears fill in the fields as described in the following table to
define this remote profile. The Remote Node Profile Menu Fields table shows you how to configure the

Generally speaking, you should employ the strongest authentication protocol possible, for obvious reasons.
However, some vendor’s 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 you encounter the case where the peer disconnects right after a
successful authentication, please make sure that you specify the correct authentication protocol when
connecting to such an implementation.

Remote Node TCP/IP Configuration
This chapter shows you how to configure the TCP/IP parameters of a remote node.
5.1 LAN-to-LAN Application
A typical LAN-to-LAN application is to use your Prestige to connect a branch office to the headquarters, as
depicted in the following diagram.
Figure 5-1 TCP/IP LAN-to-LAN Application
For the branch office, you need to configure a remote node in order to dial out to headquarters.
Additionally, you may also need to define static routes if some services reside beyond the immediate
remote LAN.

VC-based Multiplexing
Remember that for VC-based multiplexing, by prior mutual agreement, a protocol is assigned a specific
virtual circuit, e.g., VC1 will carry IP, VC2 will carry IPX, etc. However, note that for PPP or PPPoE
encapsulation, we just need 1 VC no matter what protocol (IP/IPX/Bridge) is being carried.

5.1.2 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.
Each remote node specifies only the network to which the gateway is directly connected and the Prestige
has no knowledge of the networks beyond it. For instance, the Prestige knows about network N2 in the
following diagram 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 are for you to tell the Prestige about the networks beyond the remote nodes.

The following table describes the fields for Menu 12.1 - Edit IP Static Route Setup.
Table 5-3 Edit IP Static Route Menu Fields
FIELD DESCRIPTION
Route # This is the index number of the static route that you chose in Menu 12.1.
Route Name Enter 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.
IP Subnet Mask Enter the subnet mask for this destination. Follow the discussion on IP
subnet mask in Chapter 3.
Gateway IP Address Enter 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. Enter 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.

Prestige 642R Series ADSL Router
FIELD DESCRIPTION
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 broadcast. If No, the route to this remote node will be
propagated to other hosts through RIP broadcasts.

Chapter 6
IPX Configuration
This chapter shows you how to configure the IPX parameters of the Prestige.
6.1 IPX Network Environment
Novell bundles the protocol stack, the server software and routing functionality in their NetWare server
products, so a NetWare server is not only a file or print server, it is also a router.
6.1.1 Network and Node Number
Every IPX machine has a network number and a node number, together they form the complete address of
the machine. The IPX network number is a 32-bit quantity and is usually expressed in 8 hexadecimal digits,
e.g., 0893A8CF. The host number is a 48-bit quantity and usually is taken from the MAC (Media Access
Control) address of the Ethernet hardware, so you do not have to explicitly configure the node number.
An IPX client obtains its network number from a server that has the network numbers statically configured.
If there are multiple servers on a network, only one server need to have the network numbers configured
and all other stations (clients and servers) can obtain the network numbers from it. The server with
configured network numbers is called a seed router.
If you have a NetWare server on the same LAN as the Prestige, we recommend that you set up a NetWare
server as a seed router. Even though the Prestige is capable as a seed router, a NetWare server offers a much
more extensive facility for network management.
6.1.2 Frame Types
IPX can run on top of four different frame types on the Ethernet. These frame types are 802.2, 802.3,
Ethernet II (DIX), and SNAP (Sub-Network Access Protocol). Each frame type is a separate logical
network, even though they exist on one physical network (see the following diagram).
Even though there are four frame types available on the Ethernet, you should configure as few frame types
as possible on your NetWare server and use automatic frame detection on the clients to simplify
management and to reduce network overhead.
IPX Configuration 6-1
Prestige 642R Series ADSL Router
Figure 6-1 NetWare Network Numbers
6.1.3 External Network Number
Each of the four logical networks (based on frame type) has its own external network number.
6.1.4 Internal Network Number
In addition to the external network numbers, each NetWare server has its own internal network number that
is a virtual network to which the server is attached. It is important to remember that every network number
must be unique for that entire internetwork, either internal or external.
6-2 IPX Configuration
Prestige 642R Series ADSL Router
6.2 Prestige 642R in an IPX Environment
There are two scenarios in which your Prestige is deployed, depending on whether there is a NetWare
server on the LAN, as depicted in the following diagram.
Figure 6-2 Prestige in an IPX Environment
6.2.1 Prestige 642R on LAN With Server
If your Prestige is on a LAN with a seed router, you do not need to configure the LAN network numbers.
Your Prestige will learn the network number from the seed router and add the routes to its routing table.
6.2.2 Prestige 642R on LAN Without Server
Each IPX network must have a seed router. If you only have NetWare clients on your network, then you
must configure the Prestige as a seed router and set up unique network numbers for each frame type enabled
using Ethernet Setup menu.

Chapter 7
Bridging Setup
This chapter shows you how to configure the bridging parameters of your Prestige.
7.1 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 or IPX) address. Bridging allows the Prestige to transport packets
of network layer protocols that it does not route, e.g., 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 and IPX
on your network. For IP and IPX, enable the respective routing if you need it; do not bridge what the
Prestige can route.
7.2 Bridge Ethernet Setup
Basically, all non-local packets are bridged to the WAN, however, your Prestige 642 applies special
handling for certain IPX packets to reduce the number of calls, depending on the setting of the Handle IPX
field.
Enter 4, from Menu 3 – Ethernet Setup, to bring up Menu 3.4 – Bridge Ethernet Setup as shown next.

Press the [space bar] to toggle between the options for this field.
When there is no IPX traffic on the LAN or when you do not want to apply
any special handling for IPX.
None
When there are only client workstations on the LAN. RIP and SAP (Service
Advertising Protocol) response packets will not trigger calls.
When there are only IPX servers on the LAN. No RIP or SAP packets will
trigger calls. In addition, during the time when the line is down, your
Prestige will reply to WatchDog messages from the servers on behalf of
remote clients. The period of time that your Prestige will do this is linked to
the Ethernet Address Timeout parameter in each remote node (see Remote
Node Configuration). When a remote Ethernet address is timed out, there is
no need to maintain its connection to the IPX server.
If there are both clients and servers on the LAN, and the local clients will
access the remote servers, set this field to Server but turn on the Dial-On-
Broadcast (if using PPPoE encapsulation) parameter in Menu 11.3 to allow
the client queries to trigger calls.

Filter Configuration
This chapter shows you how to create and apply filter(s).
8.1 About Filtering
Your Prestige uses filters to decide whether to allow passage of a data packet and/or to make a call. There
are two types of filter applications: data filtering and call filtering. Filters are subdivided into device and
protocol filters, which are discussed later.
Data filtering screens the data to determine if the packet should be allowed to pass. Data filters are divided
into incoming and outgoing filters, depending on the direction of the packet relative to a port. Data filtering
can be applied on either the WAN side or the Ethernet side. Call filtering is used to determine if a packet
should be allowed to trigger a call. Remote node call filtering is only applicable when using PPPoE
encapsulation. Outgoing packets must undergo data filtering before they encounter call filtering as shown in
the following figure.

For incoming packets, your Prestige applies data filters only. Packets are processed depending upon
whether a match is found. The following sections describe how to configure filter sets.
Filter Configuration 8-1
Prestige 642R Series ADSL Router
8.1.1 The Filter Structure of the Prestige
A filter set consists of one or more filter rules. Usually, you would group related rules, e.g., all the rules for
NetBIOS, into a single set and give it a descriptive name. The Prestige allows you to configure up to twelve
filter sets with six rules in each set, for a total of 72 filter rules in the system. You cannot mix device filter
rules and protocol filter rules within the same set. You can apply up to four filter sets to a particular port to
block multiple types of packets. With each filter set having up to six rules, you can have a maximum of 24
rules active for a single port.
Three sets of factory default filter rules have been configured in Menu 21 to prevent NetBIOS traffic from
triggering calls and to prevent incoming telnetting. A summary of their filter rules is shown in the figures
that follow.
The following diagram illustrates the logic flow when executing a filter rule:
