Preface

About Your Prestige

Congratulations on your purchase of the Prestige 782R G.SHDSL Router.

The Prestige is a high-performance router for Internet/LAN access via a telephone line. Your Prestige
supports multi-protocol routing for TCP/IP and Novell IPX, as well as transparent bridging for other
protocols.

The Prestige supports symmetrical multi-rate data transmission speeds from 144Kbps up to 2320Kbps. The
actual rate depends on the copper category of your telephone wires, distance from the central office and the
type of xDSL service you subscribe to. Its 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. See the following section for more background information on xDSL.

The Prestige uses TC-PAM line code with echo cancellation for high data rate transmissions over a single­twisted telephone wire pair without being affected by bridge taps or mixed cable links. It also provides high
immunity from background noise.

Your Prestige is easy to install. You do not need to set any switches to configure it. Manage the Prestige via
the SMT (System Management Terminal), a menu-driven interface, that you can access from either a
terminal emulator or telnet. Or, use the CI commands that allow users to diagnose and test the Prestige
using a specified set of commands.

Please visit our web site at www.zyxel.com for the latest release notes and product information.

Prestige 782R G.SHDSL Router

What is xDSL?

A DSL (Digital Subscriber Line) enhances the data capacity of the existing telephone line running 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 4,000Hz to filter
noise from the voice line. Several DSL services offer speeds of up to 52 Mbits/sec. DSL services are either
symmetrical (traffic flows at the same speed in both directions) or asymmetrical (the downstream capacity
is higher than the upstream capacity).

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 for DSL
maximum transmission distances. A G.SHDSL connection is a point-to-point dedicated circuit, meaning
that the link is always up and there is no dialing required.

G.SHDSL

G.SHDSL (Single-pair High-speed Digital Subscriber Line) is a symmetrical, bi-directional DSL service
that operates on one twisted-pair wire and provides data rates up to 2.3 Mbits/sec. (The “G.” in “G.SHDSL”
is defined by the G.991.2 ITU (International Telecommunication Union) state-of-the-art industry standard).

The Benefits of G.SHDSL:

• Continuous Connection

• Dedicated Bandwidth

• Investment Protection

• Low Maintenance

• Distance Capabilities

What is xDSL? xxi

You are always online.

Line speed is “symmetric,” i.e., the same bandwidth in both directions.

Scalability. Offers a flexible upgrade path. You can choose a higher
access speed yourself - no site visit is necessary.

Connectivity requires no complex manual configuration; G.SHDSL
equipment is Plug and Play.

G.SHDSL achieves 20% better loop-reach than older versions of
symmetric DSL. (Loop reach defines speed that can be attained at
various distances).

Prestige 782R G.SHDSL Router

Chapter 1

Getting to Know Your G.SHDSL Router

This chapter covers the key features and main applications of your Prestige.

The Prestige 782R Router can be used for high-speed LAN-to-LAN connections or Internet access through
a G.SHDSL connection over the telephone line. You can use your Prestige for either IP routing or bridging
depending on your ISP (Internet Service Provider) configuration.

1.1 Features of the Prestige

The following features make the Prestige a complete and the flexible networking solution for most users.

High Speed Scalability

One of the best features of G.SHDSL service is its scalability. Your Prestige G.SHDSL router supports
symmetrical multi-rate data transmission speeds from 144 Kbps up to 2320 Kbps. You can increase the
capacity of the Internet connection (within certain distance limitations) without changing your ISP or
purchasing new equipment. G.SHDSL’s high symmetrical speeds are ideal for applications like web hosting
and videoconferencing as well as the two-way data traffic needs of businesses.

Symmetrical High Speed Internet Access

The Prestige 782R supports symmetrical transmission up to 2.3 Mbps. For NSP’s (Network Service
Provider) convenience, the Prestige also supports rate management depending on distances and service
charges.

SNMP (Simple Network Management Protocol – version 1)

SNMP, a member of the TCP/IP protocol suite, allows you to exchange management information between
network devices. Your Prestige supports SNMP agent functionality that allows a manager station to manage
and monitor the Prestige through the network.

SNMP is only available if TCP/IP is configured on your Prestige.

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 RFC 2236). Both versions 1 and 2 are
supported by the Prestige.

Getting to Know Your Router 1-1

Prestige 782R G.SHDSL Router

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

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.

10/100MB Auto-negotiation Ethernet/Fast Ethernet Interface

This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately, providing a faster data transfer on the Ethernet network as required. It enables fast data
transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your
Ethernet network.

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).

Multiple Protocol Support

• Novell IPX (Internetwork Packet eXchange) network layer protocol.

• Transparent bridging for unsupported network layer protocols.

PAP and CHAP Security

The Prestige supports PAP (Password Authentication Protocol) and CHAP (Challenge Handshake
Authentication Protocol). CHAP is more secure than PAP; however, PAP is available on more platforms.

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, which means it can assign IP addresses, an IP default gateway and DNS
servers to other systems that support the DHCP client. 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.

Data Compression

Your Prestige incorporates Stac LZS data compression ratios of up to 4:1 to speed up data transfer. Stac is
the de facto standard of data compression over PPP links.

1-2 Getting to Know Your Router

Prestige 782R G.SHDSL Router

Encapsulation

The Prestige supports PPP over ATM (RFC-2364), Multiple Protocol over ATM (RFC-1483) and ENET
ENCAP.

SUA for Single-IP Address Internet Access

The Prestige’s SUA (Single User Account, equivalent to NAT) feature allows multiple user Internet access
for the cost of a single ISP account and allows multiple users on the LAN (Local Area Network) to access
the Internet concurrently. SUA supports popular Internet applications such as MS traceroute, CuSeeMe,
IRC, ICQ, RealAudio, VDOLive, Quake and PPTP. No extra configuration is needed to support these
applications. SUA address mapping can also be used for other LAN-to-LAN connections.

Full Network Management

• Menu driven SMT (System Management Terminal) management

• SNMP manageable

• Local SMT session via console port

• Remote SMT session via Telnet

Upgrade Firmware via LAN

In addition to the direct console port connection, the Prestige supports the up/downloading of firmware and
configuration file over the LAN.

Filters

The Prestige’s packet filtering functions allow added network security and management.

Ease of Installation

Your Prestige is designed for quick, easy and intuitive installation. Its compact size and light weight make it
easy to position anywhere in your busy office.

Auxiliary Port

The Prestige has another WAN port as backup in case the xDSL line degrades or is down. For small
business and home users, data applications can be more robust and flexible by connecting to an external
modem or ISDN TA.

Wall-Mounting

On the underside of the housing are two slots that can be used to wall-mount your Prestige.

2-2 Hardware Installation and Initial Setup

Prestige 782R G.SHDSL Router

Connecting your Prestige to the LAN and xDSL network.

To prevent damage to the Prestige:

DO NOT connect the G.SHDSL line to the LAN port jack.

DO NOT connect your telephone line to the xDSL RJ-11 port.

Step 1. Connecting the xDSL Line

Plug the Prestige (port labeled xDSL) into the telephone jack using the RJ-11 cable (supplied).

Step 2. Connecting the Console Port

For the initial configuration of your Prestige, you need to use terminal emulator software on a computer and
connect it to the Prestige through the console port. Connect the 9-pin end of the console cable to the console
port of the Prestige and the other 9-pin end to a serial port (COM1, COM2 or other COM port) of your
computer. You can use an extension RS-232C cable if the enclosed one is too short.

Step 3. Connecting a Computer to the Prestige

Ethernet 10Base-T networks use Unshielded Twisted Pair (UTP) cable with RJ-45 connectors that look like
a bigger telephone plug with 8 pins. Use the crossover cable to connect your Prestige to a computer directly
or use straight-through Ethernet cable to connect to an external hub and then connect one end of the
straight-through Ethernet cable from the hub to the NIC on the computer.

Step 4. Connecting the Power Adapter to your Prestige

Connect the power adapter to the port labeled POWER on the rear panel of your Prestige.

To prevent damage to the Prestige, first make sure you have the correct DC power

adapter specifications for your particular region. (See the Appendix section)

2.4 Turning On Your Prestige

You can now turn on your Prestige by flipping the power switch to the on position (I is ON, O is OFF).

Step 1. Initial Screen

Prestige 782R G.SHDSL Router

2.9.1 Note on Bridging

When bridging is enabled, your Prestige forwards any packet that it does not route. Without bridging, the
packets are simply discarded. Bridging generates far more traffic than routing for the same network
protocol and consumes more CPU cycles and memory.

The Prestige can also serve as a LAN router. To do this, in Menu 4 choose

Encapsulation = ENET ENCAP, with the Single User Account enabled (default).

Because there is only one IP address it will be assumed that there is only one

computer on the xDSL line.

2.10 Setting Up the WAN Link

Use Menu 2 – WAN Setup to configure G.SHDSL settings for your WAN line. Different telephone
companies deploy different types of G.SHDSL service. If you are unsure of any of this information, please
check with your telephone company.

2.10.1 Service Type

Is your Prestige acting as a Server or Client?

1. The Prestige is a server if it is acting as a COE (Central Office Equipment).

2. The Prestige is a client if it is acting as a CPE (Customer Premise Equipment).

2.10.2 Rate Adaption

Both the Prestige and the peer must have the same transmission rate. Rate Adaption allows the Prestige to
auto-detect the peer Transfer Rate (this feature may not be available on all models).

2.10.3 Transfer Rates

The Prestige supports the following symmetrical multi-rate data transmission speeds:

144, 200, 208, 272, 392, 400, 528, 776, 784, 1040, 1168, 1552, 2064 and 2320Kbps.

You can increase the capacity of the Internet connection (within certain limitations) without changing your
ISP or buying new equipment.

For back-to-back applications make sure that your Prestige and its peer have the same Transfer Max Rate
and the same Transfer Min Rate. Two (maximum and minimum) transfer rates are used to accommodate
fluctuations in line speed. This is known as Dynamic Bandwidth Allocation.

Internet Access

This chapter shows how to configure the LAN and WAN for Internet access.

3.1 Ethernet Factory 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 most installations. If the parameters are satisfactory, you can skip to the
TCP/IP Ethernet Setup and DHCP Section 3.3 to type the DNS server address(es) if your ISP gives you
explicit DNS server address(es). To change the factory defaults or to learn more about TCP/IP, please read
on.

3.2 TCP/IP and DHCP Ethernet Setup: DHCP

3.2.1 DHCP Setup

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 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.

3.2.2 Client 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 computers. 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 computers, e.g., server for mail, FTP, telnet, web,
etc., that you may have.

Internet Access 3-1

Prestige 782R G.SHDSL Router

3.2.3 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, a user must know the IP address of a computer before can accessing it.

Your ISP may assign you DNS server addresses in an information sheet when you sign up. If so, type them
into the DNS Server fields in DHCP Setup. If you leave this server field set to 0.0.0.0, the Prestige will act
as a DNS proxy.

Some ISP’s choose to bypass the DNS servers using the DNS server extensions of PPP IPCP (IP Control
Protocol) after connection. 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 left as 0.0.0.0, the Prestige tells the
DHCP clients that the Prestige 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 type 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.

Example of Network Properties for LAN Servers with Fixed IP#

Choose an IP: 192.168.1.2 to 192.168.1.32; 192.168.1.65 to 192.168.1.254.

Netmask: 255.255.255.0

Gateway (or default route): 192.168.1.1 (Prestige LAN IP)

3.2.4 TCP/IP and DHCP Ethernet Setup: TCP/IP

You will now use Menu 3.2 to configure your Prestige for TCP/IP.

3.2.5 IP Address and Subnet Mask

Just as apartments in the same building share a common street address, the computers on a LAN share one
common network number.

Where you obtain your network number depends on your particular circumstances. If the ISP or your
network administrator assigns you a block of registered IP addresses, follow the instructions in selecting the
IP addresses and the subnet mask.

3-2 Internet Access

Prestige 782R G.SHDSL Router

If you have a single user account, the ISP will assign you a dynamic IP address when the connection is
established. You must enable the Single User Account feature of the Prestige and choose a network number
from 192.168.0.0 to 192.168.255.0. This block of addresses has been reserved for private by The Internet
Assigned Number Authority (IANA); please do not use any other number.

For example, the IP address 192.168.1.0, covers 254 individual addresses, from 192.168.1.1 to

192.168.1.254 (zero and 255 are reserved). The first 3 numbers (192) are the network number while the last
number (0) 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 typed. You do not need to change the subnet
mask computed by the Prestige unless you are instructed to do otherwise.

Private IP Addresses

Every computer 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, it is recommended that you choose your network number from following three blocks of IP
addresses that the Internet Assigned Numbers Authority (IANA) has reserved the specifically for private
networks:

10.0.0.0 to 10.255.255.255

172.16.0.0 to 172.31.255.255

192.168.0.0 to 192.168.255.255

Your IP address can be assigned by the IANA, an ISP, or by a private network. Small organizations whose
Internet access is through an ISP, will be given Internet addresses for local networks by the ISP. Larger
organizations should consult the network administrator for the appropriate IP addresses.

Regardless of your circumstances, 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.

3.2.6 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 an unusual network topology.

Internet Access 3-3

Prestige 782R G.SHDSL Router

Both RIP-2B and RIP-2M send routing data in RIP-2 format. But RIP-2B uses subnet broadcasting while
RIP-2M uses multicasting. Multicasting reduces the load on non-router computers which generally do not

listen to the RIP multicast address and so will not receive RIP packets. However, if one router uses
multicasting, then all routers on your network must use multicasting.

By default, RIP direction is set to Both and the Version set to RIP-1.

3.2.7 Multicast

Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender – 1 recipient) or
Broadcast (1 sender – everyone on the network). Multicast is a third way to deliver IP packets to selected
group of hosts on the network.

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. For 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 IGMP 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.

3.2.8 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) and apply them on the Prestige LAN and/or WAN
interfaces using menus 3.2 (LAN) and 11.3 (WAN).

3.3 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.

3.3.1 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.

3.4.1 VPI and VCI

Be sure to use the correct VPI (Virtual Path Identifier) and VCI (Virtual Channel Identifier) numbers
supplied by the telephone company. Valid range for VPI is 0 to 255 and for the VCI is 32 to 65535 (1 to 31
is reserved for local management of ATM traffic).

3.4.2 Multiplexing

Two conventions are used in identifying what protocols the virtual circuit (VC) is carrying. Be sure to use
the multiplexing method required by your ISP.

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 number of ATM VCs is fast and economical.

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.

3.4.3 Encapsulation

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

PPP

Select this option when the peer is using a “PPP over ATM” networking model. 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.

RFC-1483

Select this option when the peer is using a “Multi-protocol over ATM” networking model. RFC-1483
describes two methods for Multi-protocol 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.

3-10 Internet Access

Prestige 782R G.SHDSL Router

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 ENET ENCAP
Gateway field in Menu 4 and in the Rem IP Addr field in Menu 11.1. You can obtain this information
from your ISP.

3.4.4 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 (SUA) feature can be enabled or disabled whether you have a
dynamic or static IP. However, the encapsulation method assigned influences your choices for IP Address
and ENET ENCAP Gateway fields.

Using PPP 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.

Using RFC-1483 Encapsulation

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

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.

If you are using PPP encapsulation, then the only ISP information needed is a

login name and password. You only need the Ethernet Encapsulation Gateway IP

address if you are using ENET ENCAP encapsulation.

3.4.5 Internet Account Information

Before you configure your Prestige for Internet access, you need to collect your Internet account
information from your ISP and telephone company.

3.4.6 Traffic Shaping

Traffic Shaping is an agreement between the carrier and the receiver to regulate the average rate and
“burstiness” or fluctuation of data transmission over an ATM network. This agreement helps eliminate
congestion that 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 is planning to send cells. This parameter
may be lower than what the bandwidth of the line permits. 1 ATM cell is 53 bytes (424 bits), so a maximum
transfer speed of 2.3Mbps gives a max PCR of 5424 cells/sec. The default value for the Prestige is 5500
cells/sec. This rate is not guaranteed.

Sustained Cell Rate (SCR) is the expected or required cell rate averaged over a long time period. This
carrier guarantees this rate as the minimum data transmission rate. SCR may not be greater than the PCR
and the Prestige default is 0 cells/sec.

Maximum Burst Size (MBS) is the maximum number of cells that may be sent at the PCR rate in a given
time period. The following figure illustrates the relationship between PCR, SCR and MBS.

Prestige 782R G.SHDSL Router

3.6 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). SUA supports popular Internet applications such as MS traceroute,
CuSeeMe, IRC, RealAudio, VDOLive, Quake and PPTP with no extra configuration needed.

Figure 3-8 Single User Account Topology

The Single User Account feature may also be used on connections to remote networks other than the ISP.
For example, this feature can be used to simplify the allocation of IP addresses when connecting branch
offices to the corporate network.

The IP address for the SUA can be either fixed or dynamically assigned. In addition, you can designate
servers, e.g., a web server on your local network and make them accessible to 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 and 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).

Internet Access 3-15

Prestige 782R G.SHDSL Router

3.6.1 Advantages of SUA

• SUA is a cost-effective solution for small offices with less than 20 hosts for accessing the Internet or

other remote TCP/IP networks.

• SUA provides firewall protection if no server is specified. All incoming inquiries will be filtered out.

• UDP and TCP datagrams can be routed. Also supported are partial ICMP, echo (ping) and trace route.

3.6.2 Single User Account Configuration

Configuring for Single User Account is the same as for the conventional Internet access except that you
need to fill in two extra fields in Menu 4 – Internet Access Setup, as shown in the following figure. SUA

3.7 Multiple Servers Behind the SUA

You can make inside servers for different services, e.g., web or FTP, visible to the outside users, even
though SUA makes your whole internal network appear as a single computer 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 192.168.1.36 and an FTP server at 192.168.1.33, then you need
to specify for port 80 (web) the server at IP address 192.168.1.36 and for port 21 (FTP) another at IP
address 192.168.1.33.

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.

3.7.1 Configuring a Server Behind the SUA

Do the following steps to configure a server behind SUA:

Step 1. Type 15 in the main menu to go to Menu 15 – SUA Server Setup.

Step 2. Type the service port number in the Port # field and the inside IP server address in the IP

Address field.

Chapter 4

Remote Node Configuration

This chapter covers the parameters that are protocol-independent. The protocol-dependent

configuration (TPP/IP, IPX and Bridging) is covered in the next 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, select menu option 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, e.g., branch office and corporate headquarters, prior agreement on methods is
necessary because encapsulation and multiplexing cannot be automatically determined. Which methods to
use depends on how many VCs you have and how many different network protocols you need. The extra
overhead that 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 no extra
protocol identifying headers are needed. The PPP 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 PPP 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.

For obvious reasons, you should employ the strongest authentication protocol possible. 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 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.

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 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.

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.

IP Subnet Mask Type the subnet mask for this destination. Follow the discussion on IP subnet

mask in this chapter.

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

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 computer has a network number and a node number, together they form the complete address of
the computer. 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 782 , 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 4 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 782R G.SHDSL Router

Figure 6-1 NetWare Network Numbers

6.1.3 External Network Number

Each of the 4 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 network, both internal or external.

6.2 The Prestige in an IPX Environment

There are two scenarios in which your Prestige 782R is deployed, depending on whether there is a NetWare
server on the LAN or not, as depicted in the following diagram.

• LAN with a server (server side)

• LAN without a server (client side)

Figure 6-2 Prestige in an IPX Environment

6.2.1 The Prestige on a LAN with a 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 The Prestige on a 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 Menu 3 – 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 reason, 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 applies special handling
for certain IPX packets to reduce the number of calls, depending on the setting of the Handle IPX field.

From Menu 3 – Ethernet Setup, type 4 to enter Bridge Setup as shown next.

When no IPX traffic is on the LAN or when you do not want any special handling for IPX.

When only client workstations are on the LAN. RIP and SAP (Service Advertising Protocol)
response packets will not trigger calls.

Server

When only IPX servers are on the LAN. No RIP or SAP packets will trigger calls. Also, when
the line is down, your Prestige will reply to watchdog messages from the servers on behalf
of remote clients. How long 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 aged out, there is no need to maintain its connection to the IPX server.

7.2.1 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

Filter Configuration

This chapter shows you how to create and apply filters.

8.1 About Filtering

Your Prestige uses filters to decide whether or not 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.

Outgoing packets must undergo data filtering before they encounter call filtering. Call filters are divided
into two groups, the built-in call filters and user-defined call filters. Your Prestige has built-in call filters
that prevent administrative, e.g., RIP packets from triggering calls. These filters are always enabled and not
accessible to you. Your Prestige applies the built-in filters first and then the user-defined call filters, if
applicable, as shown next.

8-2 Filter Configuration

Prestige 782R G.SHDSL Router

You can apply up to four filter sets to a particular port to block various types of packets. Because each filter
set can have up to six rules, you can have a maximum of 24 rules active for a single port.

For incoming packets, your Prestige applies data filters only. Packets are processed depending on whether a
match is found. The following sections describe how to configure filter sets.

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. You can configure up to twelve filter sets with six
rules in each set, for a total of 72 filter rules in the system.

You can apply up to 4 filter sets to a particular port to block multiple types of packets. Because each filter
set can have up to 6 rules, you can have a maximum of 24 rules active for a single port.

8.3 Configuring a Filter Rule

To configure a filter rule, Type its number in Menu 21.1 – Filter Rules Summary and press [ENTER] to
open Menu 21.1.1 for the rule.

There are three types of filter rules: TCP/IP, IPX and Generic. Depending on the type of rule, the
parameters for each the type will be different. Use [SPACE BAR] to select the type of rule that you want to
create in the Filter Type field and press [ENTER] to open the respective menu.

To speed up filtering, all rules in a filter set must be of the same class, i.e., protocol filters or generic filters.
The class of a filter set is determined by the first rule that you create. When applying the filter sets to a port,
separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set in a
device filters field or vice versa, the Prestige will warn you and will not allow you to save.

8.3.2 Generic Filter Rule

This section shows you how to configure a generic filter rule. The purpose of generic rules is to allow you
to filter non-IP packets. For IP, it is generally easier to use the IP rules directly.

For generic rules, the Prestige treats a packet as a byte stream as opposed to an IP or IPX packet. You
specify the portion of the packet to check with the Offset (from 0) and the Length fields, both in bytes. The
Prestige applies the Mask (bit-wise ANDing) to the data portion before comparing the result against the
Value to determine a match. The Mask and Value are specified in hexadecimal numbers.

Two hexadecimal digits represent a byte, so if the length is 4, the value in either

field will take 8 digits, e.g., FFFFFFFF.

To configure a generic rule select an empty filter set in menu 21, for eg., 5. Select the Generic Filter Rule
