Prestige 650H ADSL Router
Preface
There are two Prestige 650H models, one for ADSL over POTS (Plain Old Telephone System) and one for
ADSL over ISDN (Integrated Synchronous Digital System). Both models are discussed together in this
guide.
The P650H ADSL router is the ideal all-in-one device for small networks connecting to the Internet via
ADSL. You don’t need to buy an external hub. The P650H is equipped with four auto-sensing
10/100BASE-T Ethernet ports to connect to your network and an RJ-11 port (POTS) or RJ-45 port (ISDN)
to connect to your ADSL service.
The P650H'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 using either a
crossover or straight-through Ethernet cable.
The Prestige 650H is interoperable with all major DSLAM solutions vendors. The P650H can run
maximum upstream transmission rates of up to 832Kbps and maximum downstream transmission rates of
8Mbps. The actual rate depends on the copper category of your telephone wire, distance from the central
office and the type of ADSL service subscribed to. See the What is DSL section for more background
information on DSL and ADSL
In addition, the Prestige 650H has bridging and IP routing to support a wide range of applications for highspeed Internet access.
Your Prestige is easy to install and configure. All functions are configurable via the SMT (System
Management Terminal) and web configurator. Advanced users may configure the Prestige using CLI
(Command Line Interface) commands.
Don’t forget to register your Prestige (fast, easy online registration at

Preface
Prestige 650H ADSL Router
What is DSL?
DSL (Digital Subscriber Line) technology enhances the data capacity of the existing twisted-pair wire that
runs between the local telephone company switching offices and most homes and offices. While the wire
itself can handle higher frequencies, the telephone switching equipment is designed to cut off signals above
4,000 Hz to filter noise off the voice line, but now everybody is searching for ways to get more bandwidth to
improve access to the Web - hence DSL technologies.
There are actually seven types of DSL service, ranging in speeds from 16 Kbits/sec to 52 Mbits/sec. The
services are either symmetrical (traffic flows at the same speed in both directions), or asymmetrical (the
downstream capacity is higher than the upstream capacity). Asymmetrical services (ADSL) are suitable for
Internet users because more information is usually downloaded than uploaded. For example, a simple button
click in a web browser can start an extended download that includes graphics and text.
As data rates increase, the carrying distance decreases. That means that users who are beyond a certain
distance from the telephone company’s central office may not be able to obtain the higher speeds.
A DSL connection is a point-to-point dedicated circuit, meaning that the link is always up and there is no
dialing required.
What is ADSL?
It is an asymmetrical technology, meaning that the downstream data rate is much higher than the upstream
data rate. As mentioned, this works well for a typical Internet session in which more information is
downloaded, for example, from Web servers, than is uploaded. ADSL operates in a frequency range that is
above the frequency range of voice services, so the two systems can operate over the same cable.

Chapter 1
Getting To Know Your Prestige
This chapter describes the key features and applications of your Prestige.
1.1
Prestige P650H 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 P650H
Your Prestige is packed with a number of features that give it the flexibility to provide a complete
networking solution for almost any user.
High Speed Internet Access
Your Prestige ADSL router can support downstream transmission rates of up to 8Mbps and upstream
transmission rates of 832 Kbps.
PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their
existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the
Prestige is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual computers.
Getting To Know Your Prestige
1-1
Prestige 650H ADSL Router
NAT for Single-IP-address Internet Access
The Prestige's SUA (Single User Account) feature allows multiple-user Internet access for the cost of a
single IP account. NAT supports popular Internet applications such as MS traceroute, CuSeeMe, IRC,
RealPlayer, VDOLive, Quake, and PPTP. No configuration is needed to support these applications.
10/100M Auto-negotiation Ethernet/Fast Ethernet Interface
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either
half-duplex or full-duplex mode depending on your Ethernet network.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the
host to be more easily accessible from various locations on the Internet. You must register for this service
with a Dynamic DNS client.
Multiple PVC (Permanent Virtual Circuits) Support
Your Prestige supports up to 8 PVC’s.
ADSL Transmission Rate Standards
♦ Full-Rate (ANSI T1.413, Issue 2; G.dmt (G.992.1) with line rate support of up to 8 Mbps
downstream and 832 Kbps upstream.
♦ G.lite (G.992.2) with line rate support of up to 1.5Mbps downstream and 512Kbps upstream.
♦ Supports Multi-Mode standard (ANSI T1.413, Issue 2; G.dmt (G.992.1); G.994.1; G.996.1;
G.991.1;G.lite (G992.2)).

♦ RFC 1661.
♦ PPP over PAP (RFC 1334).
♦ PPP over CHAP (RFC 1994).
•
Protocol Support
♦
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain
the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in
DHCP server capability enabled by default. It can assign IP addresses, an IP default gateway and
DNS servers to DHCP clients. The Prestige can now also act as a surrogate DHCP server (DHCP
Relay) where it relays IP address assignment from the actual real DHCP server to the clients.
♦ IP Alias
IP Alias allows you to partition a physical network into logical networks over the same Ethernet
interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet
interface with the Prestige itself as the gateway for each LAN network.
♦
IP Policy Routing (IPPR)
Traditionally, routing is based on the destination address only and the router takes the shortest path
to forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default
routing behavior and alter the packet forwarding based on the policy defined by the network
administrator.
♦

Hardware Installation and Initial Setup
2-3
Prestige 650H ADSL Router
2.2.2 Four LAN 10/100M Ports
Ethernet 10Base-T/100Base-T networks use Shielded Twisted Pair (STP) cable with RJ-11 (POTS)
connectors or RJ-45 (ISDN) connectors that look like a bigger telephone plug with 8 pins. All LAN ports
are auto-sensing, so you may use the crossover cable provided or a straight-through Ethernet cable to
connect your Prestige to a computer/external hub.
When the Prestige is on and properly connected to a computer or a hub, the
corresponding LAN LED on the front panel turns on.
2.2.3 Power Port
Connect the power adapter to the port labeled POWER on the rear panel of your Prestige. Push in the power
button when you want to turn on the Prestige.
To avoid damage to the Prestige, make sure you use the correct power adapter.
Refer to the Power Adapter Specification Appendix for this information.
2.2.4 Restore Factory Defaults/Reboot Button
Hold this button in for between 1 and 3 seconds to restart the Prestige.
Upload the default configuration file by holding this button in for more than 3 seconds. Refer to section 2.8
for information on the resetting your Prestige.
2.3
Additional Installation Requirements
A computer with an Ethernet 10Base-T/100Base-T NIC (Network Interface Card).
A computer equipped with a web browser (enable JavaScript) and/or Telnet.
2.4
P650H with POTS
Sections 2.4.1 and 2.4.2 relate to people who use their P650H with ADSL over POTS (analog telephone
service) only.
2.4.1 Connecting a POTS Splitter
This is for the Prestige that follows the Full Rate (G.dmt) standard only. One major difference between
ADSL and dial-up modems is the optional telephone splitter. This device keeps the telephone and ADSL
signals separated, giving them the capability to provide simultaneous Internet access and telephone service
on the same line. Splitters also eliminate the destructive interference conditions caused by telephone sets.
The purchase of a POTS splitter is optional.
2-4
Hardware Installation and Initial Setup
Prestige 650H ADSL Router
Noise generated from a telephone in the same frequency range, as the ADSL signal can be disruptive to the
ADSL signal. In addition the impedance of a telephone when off-hook may be so low that it shunts the
strength of the ADSL signal. When a POTS splitter is installed at the entry point, where the line comes into
the home, it will filter the telephone signals before combining the ADSL and telephone signals transmitted
and received. The issues of noise and impedance are eliminated with a single POTS splitter installation.
A telephone splitter is easy to install as shown in the following figure.
Figure 2-3 Connecting a POTS Splitter
Step 1.
Connect the side labeled “Phone” to your telephone.
Step 2.
Connect the side labeled “Modem” to your Prestige.
Step 3.
Connect the side labeled “Line” to the telephone wall jack.
2.4.2 Telephone Microfilters
Telephone voice transmissions take place in the lower frequency range, 0 - 4KHz, while ADSL
transmissions take place in the higher bandwidth range, above 4KHz. A microfilter acts as a low-pass filter,
for your telephone, to ensure that ADSL transmissions do not interfere with your telephone voice
transmissions. The purchase of a telephone microfilter is optional.
Step 1.
Connect a phone cable from the wall jack to the single jack end of the Y- Connector.
Step 2.
Connect a cable from the double jack end of the Y-Connector to the “wall side” of the
microfilter.
Step 3.
Connect another cable from the double jack end of the Y-Connector to the Prestige.
Step 4.
Connect the “phone side” of the microfilter to your telephone as shown in the following figure.

Resetting the Prestige
If you forget your password or cannot access the Prestige, you will need to reload the factory-default
configuration file. Uploading this configuration file replaces the current configuration file with the factorydefault configuration file. This means that you will lose all configurations that you had previously; the
password will be reset to “1234” and the LAN IP address to 192.168.1.1.
To obtain the default configuration file, download it from the ZyXEL FTP site, unzip it and save it in a
folder.
2.8.1 Methods of Restoring Factory-Defaults
You can erase the current configuration and restore factory defaults in three ways:
1.
Transfer the configuration file to your Prestige using the SMT menus. See later in this User’s Guide for
more information on this.
2.
Use the Restore Factory Defaults/Reboot button on the rear panel of the Prestige to upload the
default configuration file (hold this button in for more than 3 seconds). Use this method for cases when
the password or IP address of the Prestige is not known.
3.
Use the web configurator to restore defaults (see the web configurator HTML help)

The Domain Name entry is what is propagated to the DHCP clients on the LAN. If you leave this blank,
the domain name obtained by DHCP from the ISP is used. While you must enter the host name (System
Name) on each individual computer, the domain name can be assigned from the Prestige via DHCP.
2.11.1 Dynamic DNS
Dynamic DNS (Domain Name System) allows you to update your current dynamic IP address with one or
many dynamic DNS services so that anyone can contact you (in NetMeeting, CU-SeeMe or other services).
You can also access your FTP server or Web site on your own computer using a DNS-like address (for
example, myhost.dhs.org, where myhost is a name of your choice) which will never change instead of using
an IP address that changes each time you reconnect. Your friends or relatives will always be able to call you
even if they don't know your IP address.
First of all, you need to have registered a dynamic DNS account with www.dyndns.org. This is for people
with a dynamic IP from their ISP or DHCP server that would still like to have a DNS name.
To use this service, you must register with the Dynamic DNS service provider. The Dynamic DNS service
provider will give you a password or key. The Prestige supports www.dyndns.org. You can apply to this
service provider for Dynamic DNS service.
DYNDNS Wildcard
Enabling the wildcard feature for your host causes *.yourhost.dyndns.org to be aliased to the same IP
address as yourhost.dyndns.org. This feature is useful if you want to be able to use, for example,
www.yourhost.dyndns.org and still reach your hostname.

Chapter 3
Internet Access
This chapter shows you how to configure the LAN and WAN of your Prestige for Internet access.
3.1
Factory Ethernet Defaults
The Ethernet parameters of the Prestige are preset in the factory with the following values:
1.
IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
2.
DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to TCP/IP Ethernet Setup and DHCP to enter the DNS server address(es) if your ISP gives you explicit
DNS server address(es). If you wish to change the factory defaults or to learn more about TCP/IP, please
read on.
3.2
LANs and WANs
A LAN (Local Area Network) is a computer network limited to the immediate area, usually the same
building or floor of a building. A WAN (Wide Area Network), on the other hand, is an outside connection
to another network or the Internet.
3.2.1 LANs, WANs and the Prestige
The actual physical connection determines whether the Prestige ports are LAN or WAN ports. There are
two separate IP networks, one inside, the LAN network; the other outside: the WAN network as shown
next:
Internet Access
3-1
Prestige 650H ADSL Router
Figure 3-1 LAN & WAN IPs
3.3
TCP/IP Parameters
3.3.1 IP Address and Subnet Mask
Like houses on a street that share a common street name, the computers on a LAN share one common
network number.
Where you obtain your network number depends on your particular situation. If the ISP or your network
administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP
addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user account
and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing
zero) and you must enable the Single User Account feature of the Prestige. The Internet Assigned Number
Authority (IANA) reserved this block of addresses specifically for private use; please do not use any other
number unless you are told otherwise. Let’s say you select 192.168.1.0 as the network number; which
covers 254 individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other
words, the first three numbers specify the network number while the last number identifies an individual
computer on that network.
The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the
subnet mask automatically based on the IP address that you entered. You don’t need to change the subnet
mask computed by the Prestige unless you are instructed to do otherwise.
3-2
Internet Access
Prestige 650H ADSL Router
3.3.2 Private IP Addresses
Every machine on the Internet must have a unique address. If your networks are isolated from the Internet,
for example, only between your two branch offices, you can assign any IP addresses to the hosts without
problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three
blocks of IP addresses specifically for private networks:
10.0.0.0
—
10.255.255.255
172.16.0.0
—
172.31.255.255
192.168.0.0
—
192.168.255.255
You can obtain your IP address from the IANA, from an ISP or it can be assigned from a private network.
If you belong to a small organization and your Internet access is through an ISP, the ISP can provide you
with the Internet addresses for your local networks. On the other hand, if you are part of a much larger
organization, you should consult your network administrator for the appropriate IP addresses.
Note: Regardless of your particular situation, do not create an arbitrary IP
address; always follow the guidelines above. For more information on address
assignment, please refer to RFC 1597, Address Allocation for Private Internets
and RFC 1466, Guidelines for Management of IP Address Space.
3.3.3 RIP Setup
RIP (Routing Information Protocol) allows a router to exchange routing information with other routers.
The RIP Direction field controls the sending and receiving of RIP packets. When set to:
1.
Both - the Prestige will broadcast its routing table periodically and incorporate the RIP information
that it receives.
2.
In Only - the Prestige will not send any RIP packets but will accept all RIP packets received.
3.
Out Only - the Prestige will send out RIP packets but will not accept any RIP packets received.
4.
None - the Prestige will not send any RIP packets and will ignore any RIP packets received.
The Version field controls the format and the broadcasting method of the RIP packets that the Prestige
sends (it recognizes both formats when receiving). RIP-1 is universally supported; but RIP-2 carries more
information. RIP-1 is probably adequate for most networks, unless you have an unusual network topology.
Both RIP-2B and RIP-2M sends the routing data in RIP-2 format; the difference being that RIP-2B uses
subnet broadcasting while RIP-2M uses multicasting.
Internet Access
3-3
Prestige 650H ADSL Router
3.3.4 DHCP Configuration
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server
capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS
servers to Windows 95, Windows NT and other systems that support the DHCP client. The Prestige can
also act as a surrogate DHCP server where it relays IP address assignment from the actual DHCP server to
the clients.
IP Pool Setup
The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64 for
the client machines. This leaves 31 IP addresses, 192.168.1.2 to 192.168.1.32 (excluding the Prestige itself
which has a default IP of 192.168.1.1) for other server machines, for example, server for mail, FTP, telnet,
web, etc., that you may have.
DNS Server Address
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa,
for example, the IP address of www.zyxel.com is 204.217.0.2. The DNS server is extremely important
because without it, you must know the IP address of a machine before you can access it. The DNS server
addresses that you enter in the DHCP setup are passed to the client machines along with the assigned IP
address and subnet mask.
There are two ways that an ISP disseminates the DNS server addresses. The first is for an ISP to tell a
customer the DNS server addresses, usually in the form of an information sheet, when s/he signs up. If
your ISP does give you the DNS server addresses, enter them in the DNS Server fields in DHCP Setup,
otherwise, leave them blank.
Some ISP’s choose to pass the DNS servers using the DNS server extensions of PPP IPCP (IP Control
Protocol) after the connection is up. If your ISP did not give you explicit DNS servers, chances are the
DNS servers are conveyed through IPCP negotiation. The Prestige supports the IPCP DNS server
extensions through the DNS proxy feature.
If the Primary and Secondary DNS Server fields in DHCP Setup are not specified, for instance, left as
0.0.0.0, the Prestige tells the DHCP clients that it itself is the DNS server. When a computer sends a DNS
query to the Prestige, the Prestige forwards the query to the real DNS server learned through IPCP and
relays the response back to the computer.
Please note that DNS proxy works only when the ISP uses the IPCP DNS server extensions. It does not
mean you can leave the DNS servers out of the DHCP setup under all circumstances. If your ISP gives you
explicit DNS servers, make sure that you enter their IP addresses in the DHCP Setup menu. This way, the
Prestige can pass the DNS servers to the computers and the computers can query the DNS server directly
without the Prestige’s intervention.
3-4
Internet Access
Prestige 650H ADSL Router
3.4
IP Multicast
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender – 1 recipient) or
Broadcast (1 sender – everybody on the network). Multicast is a third way to deliver IP packets to a group
of hosts on the network - not everybody.
IGMP (Internet Group Multicast Protocol) is a session-layer protocol used to establish membership in a
multicast group - it is not used to carry user data. IGMP version 2 (RFC 2236) is an improvement over
version 1 (RFC 1112) but IGMP version 1 is still in wide use. If you would like to read more detailed
information about interoperability between IGMP version 2 and version 1, please see sections 4 and 5 of
RFC 2236. The class D IP address is used to identify host groups and can be in the range 224.0.0.0 to
239.255.255.255. The address 224.0.0.0 is not assigned to any group and is used by IP multicast computers.
The address 224.0.0.1 is used for query messages and is assigned to the permanent group of all IP hosts
(including gateways). All hosts must join the 224.0.0.1 group in order to participate in IGMP. The address
224.0.0.2 is assigned to the multicast routers group.
The Prestige supports both IGMP version 1 (IGMP-v1) and version 2 (IGMP-v2). At start up, the Prestige
queries all directly connected networks to gather group membership. After that, the Prestige periodically
updates this information. IP Multicasting can be enabled/disabled on the Prestige LAN and/or WAN
interfaces using menus 3.2 (LAN) and 11.3 (WAN). Select None to disable IP Multicasting on these
interfaces.
3.5
IP Policies
Traditionally, routing is based on the destination address only and the router takes the shortest path to
forward a packet. IP Policy Routing (IPPR) provides a mechanism to override the default routing behavior
and alter the packet forwarding based on the policy defined by the network administrator. Policy-based
routing is applied to incoming packets on a per interface basis, prior to the normal routing. Create policies
using SMT menu 25 (see IP Policy Routing) and apply them on the Prestige LAN and/or WAN interfaces
using menus 3.2 (LAN) and 11.3 (WAN).
3.6
IP Alias
IP Alias allows you to partition a physical network into different logical networks over the same Ethernet
interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet interface with
the Prestige itself as the gateway for each LAN network.

VPI and VCI
Be sure to use the correct Virtual Path Identifier (VPI) and Virtual Channel Identifier (VCI) numbers
supplied by your telephone company. The valid range for the VPI is 0 to 255 and for the VCI is 32 to
65535 (0 to 31 is reserved for local management of ATM traffic). Please see the Appendices for more
information.
3.10 Multiplexing
There are two conventions to identify what protocols the virtual circuit (VC) is carrying. Be sure to use the
multiplexing method required by your ISP.
3.10.1 VC-based Multiplexing
In this case, by prior mutual agreement, each protocol is assigned to a specific virtual circuit, for example,
VC1 carries IP, etc. VC-based multiplexing may be dominant in environments where dynamic creation of
large numbers of ATM VCs is fast and economical.
3.10.2 LLC-based Multiplexing
In this case one VC carries multiple protocols with protocol identifying information being contained in each
packet header. Despite the extra bandwidth and processing overhead, this method may be advantageous if it
is not practical to have a separate VC for each carried protocol, for example, if charging heavily depends on
the number of simultaneous VCs.
3.11 Encapsulation
Be sure to use the encapsulation method required by your ISP. The Prestige supports the following
methods.
3.11.1 ENET ENCAP
The MAC Encapsulated Routing Link Protocol (ENET ENCAP) is only implemented with the IP network
protocol. IP packets are routed between the Ethernet interface and the WAN interface and then formatted so
that they can be understood in a bridged environment for instance, it encapsulates routed Ethernet frames
into bridged ATM cells. ENET ENCAP requires that you specify a gateway IP address in the Ethernet
Encapsulation Gateway field in menu 4 and in the Rem IP Addr field in menu 11.1. You can get this
information from your ISP.
Internet Access
3-11
Prestige 650H ADSL Router
3.11.2 PPP over Ethernet
PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
The Prestige bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your computer to an
ATM PVC (Permanent Virtual Circuit) which connects to a xDSL Access Concentrator where the PPP
session terminates. One PVC can support any number of PPP sessions from your LAN. For more
information on PPPoE, see the Appendices.
3.11.3 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.
3.12.3 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
3-12
Internet Access
Prestige 650H ADSL Router
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

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

Remote Node Configuration
This chapter covers the parameters that are protocol-independent. Protocol-dependent
configuration (TCP/IP and Bridging) is covered in the following chapters.
A remote node is required for placing calls to a remote gateway. A remote node represents both the remote
gateway and the network behind it across a WAN connection. When you use menu 4 to set up Internet
access, you are configuring one of the remote nodes.

4.1.2 Encapsulation and Multiplexing Scenarios
For Internet access you should use the encapsulation and multiplexing methods used by your ISP. For
LAN-to-LAN applications, for example, between a branch office and corporate headquarters, prior
agreement on methods is necessary because encapsulation and multiplexing cannot be automatically
determined. What method(s) you use depends on how many VCs you have and how many different network
protocols you need. The extra overhead that ENET ENCAP encapsulation entails makes it a poor choice in
a LAN-to-LAN application. Here are some examples of more suitable combinations in such an application.
Scenario 1.
One VC, Multiple Protocols
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.
4-2
Remote Node Configuration
Prestige 650H ADSL Router
Nailed-Up Connection (PPP)
A nailed-up connection is a dial-up line where the connection is always up regardless of traffic demand.
The Prestige does two things when you specify a nailed-up connection. The first is that idle timeout is
disabled. The second is that the Prestige will try to bring up the connection when turned on and whenever
the connection is down. A nailed-up connection can be very expensive for obvious reasons.
Do not specify a nailed-up connection unless your telephone company offers flat-rate service or you need a
constant connection and the cost is of no concern

5.1.2 IP Static Route Setup
Static routes tell the Prestige routing information that it cannot learn automatically through other means.
This can arise in cases where RIP is disabled on the LAN or a remote network is beyond the one that is
directly connected to a remote node.
Remote Node TCP/IP Configuration
5-5
Prestige 650H ADSL Router
Each remote node specifies only the network to which the gateway is directly connected and the Prestige
has no knowledge of the networks beyond. For instance, the Prestige knows about network N2 in the
following figure through remote node Router 1. However, the Prestige is unable to route a packet to
network N3 because it does not know that there is a route through remote node Router 1 (via Router 2). The
static routes allow you to tell the Prestige about the networks beyond the remote nodes.

Chapter 6
Bridging Setup
This chapter shows you how to configure the bridging parameters of your Prestige.
6.1
Bridging in General
Bridging bases the forwarding decision on the MAC (Media Access Control), or hardware address, while
routing does it on the network layer (IP) address. Bridging allows the Prestige to transport packets of
network layer protocols that it does not route, for example, SNA, from one network to another. The caveat
is that, compared to routing, bridging generates more traffic for the same network layer protocol, and it also
demands more CPU cycles and memory.
For efficiency reasons, do not turn on bridging unless you need to support protocols other than IP on your
network. For IP, enable the routing if you need it; do not bridge what the Prestige can route.
6.2
Bridge Ethernet Setup
Basically, all non-local packets are bridged to the WAN. Your Prestige does not support IPX.
6.2.1 Remote Node Bridging Setup
Follow the procedure in another section to configure the protocol-independent parameters in Menu 11.1 –
Remote Node Profile. For bridging-related parameters, you need to configure Menu 11.3 – Remote Node
Network Layer Options.
To setup Menu 11.3 – Remote Node Network Layer Options shown in the next figure, follow these steps:
Step 1.
In menu 11.1, make sure the Bridge field is set to Yes.

Chapter 7
Network Address Translation (NAT)
This chapter discusses how to configure NAT on the Prestige.
7.1
Introduction
NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a
packet, for example, the source address of an outgoing packet, used within one network to a different IP
address known within another network.
7.1.1 NAT Definitions
Inside/outside denotes where a host is located relative to the Prestige, for example, the computers of your
subscribers are the inside hosts, while the web servers on the Internet are the outside hosts.
Global/local denotes the IP address of a host in a packet as the packet traverses a router, for example, the
local address refers to the IP address of a host when the packet is in the local network, while the global
address refers to the IP address of the host when the same packet is traveling in the WAN side.
Note that inside/outside refers to the location of a host, while global/local refers to the IP address of a host
used in a packet. Thus, an inside local address (ILA) is the IP address of an inside host in a packet when
the packet is still in the local network, while an inside global address (IGA) is the IP address of the same
inside host when the packet is on the WAN side. The following table summarizes this information.
Table 7-1 NAT Definitions
ITEM
DESCRIPTION
Inside
This refers to the host on the LAN.
Outside
This refers to the host on the WAN.
Local
This refers to the packet address (source or destination) as the packet travels on the LAN.
Global
This refers to the packet address (source or destination) as the packet travels on the WAN.
NAT
7-1
Prestige 650H ADSL Router
NAT never changes the IP address (either local or global) of an outside host.
7.1.2 What NAT Does
In the simplest form, NAT changes the source IP address in a packet received from a subscriber (the inside
local address) to another (the inside global address) before forwarding the packet to the WAN side. When
the response comes back, NAT translates the destination address (the inside global address) back to the
inside local address before forwarding it to the original inside host. Note that the IP address (either local or
global) of an outside host is never changed.
The global IP addresses for the inside hosts can be either static or dynamically assigned by the ISP. In
addition, you can designate servers, for example, a web server and a telnet server, on your local network
and make them accessible to the outside world. Although you can make designated servers on the LAN
accessible to the outside world, it is strongly recommended that you attach those servers to the DMZ port
instead. If you do not define any servers (for Many-to-One and Many-to-Many Overload mapping – see
Table 7-2), NAT offers the additional benefit of firewall protection. With no servers defined, your Prestige
filters out all incoming inquiries, thus preventing intruders from probing your network. For more
information on IP address translation, refer to RFC 1631, The IP Network Address Translator (NAT).
7.1.3 How NAT Works
Each packet has two addresses – a source address and a destination address. For outgoing packets, the ILA
(Inside Local Address) is the source address on the LAN, and the IGA (Inside Global Address) is the source
address on the WAN. For incoming packets, the ILA is the destination address on the LAN, and the IGA is
the destination address on the WAN. NAT maps private (local) IP addresses to globally unique ones
required for communication with hosts on other networks. It replaces the original IP source address (and
TCP or UDP source port numbers for Many-to-One and Many-to-Many Overload NAT mapping) in each
packet and then forwards it to the Internet. The Prestige keeps track of the original addresses and port
numbers so incoming reply packets can have their original values restored. The following figure illustrates
this.
7-2
NAT
Prestige 650H ADSL Router
Figure 7-1 How NAT Works
7.1.4 NAT Application
The following figure illustrates a possible NAT application, where three inside LANs (logical LANs using
IP Alias) behind the Prestige can communicate with three distinct WAN networks. More examples follow at
the end of this chapter.
NAT

Figure 7-2 NAT Application With IP Alias
7.1.5 NAT Mapping Types
NAT supports five types of IP/port mapping. They are:
1.
One to One: In One-to-One mode, the Prestige maps one local IP address to one global IP address.
2.
Many to One: In Many-to-One mode, the Prestige maps multiple local IP addresses to one global IP
address. This is equivalent to SUA (for instance, PAT, port address translation), ZyXEL’s Single User
Account feature that previous ZyXEL routers supported (the SUA Only option in today’s routers).
3.
7-4
Many to Many Overload: In Many-to-Many Overload mode, the Prestige maps the multiple local IP
addresses to shared global IP addresses.
NAT
Prestige 650H ADSL Router
4.
Many-to-Many No Overload: In Many-to-Many No Overload mode, the Prestige maps each local IP
address to a unique global IP address.
5.
Server: This type allows you to specify inside servers of different services behind the NAT to be
accessible to the outside world although, it is highly recommended that you use the DMZ port for these
servers instead.
Port numbers do not change for One-to-One and Many-to-Many No Overload NAT
mapping types.
The following table summarizes these types.

Using NAT
7.2.1 SUA (Single User Account) Versus NAT
SUA (Single User Account) is a ZyNOS implementation of a subset of NAT that supports two types of
mapping, Many-to-One and Server. See section 7.3.1 for a detailed description of the NAT set for SUA.
The Prestige also supports Full Feature NAT to map multiple global IP addresses to multiple private LAN
IP addresses of clients or servers using mapping types as outlined in Table 7-2.
1. Choose SUA Only if you have just one public WAN IP address for your Prestige.
2. Choose Full Feature if you have multiple public WAN IP addresses for your Prestige.

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

ignored. If there are any empty rules before your new configured rule, your configured rule will be pushed
up by that number of empty rules. For example, if you have already configured rules 1 to 6 in your current
set and now you configure rule number 9. In the set summary screen, the new rule will be rule 7, not 9.
Now if you delete rule 4, rules 5 to 7 will be pushed up by 1 rule, so as old rule 5 becomes rule 4, old rule 6
becomes rule 5 and old rule 7 becomes rule 6.

7.4
NAT Server Sets – Port Forwarding
A NAT server set is a list of inside (behind NAT on the LAN) servers, for example, web or FTP, that you
can make visible to the outside world even though NAT makes your whole inside network appear as a
single machine to the outside world.
Use Menu 15 - NAT Setup to forward incoming service requests to the server(s) on your local network.
You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of
the desired server. The port number identifies a service; for example, web service is on port 80 and FTP on
port 21. In some cases, such as for unknown services or where one server can support more than one service
(for example both FTP and web service), it might be better to specify a range of port numbers.
In addition to the servers for specified services, NAT supports a default server. A service request that does
not have a server explicitly designated for it is forwarded to the default server. If the default is not defined,
the service request is simply discarded.
Many residential broadband ISP accounts do not allow you to run any server
processes (such as a Web or FTP server) from your location. Your ISP may
periodically check for servers and may suspend your account if it discovers any
active services at your location. If you are unsure, refer to your ISP.
The most often used port numbers are shown in the following table. Please refer to RFC 1700 for further
information about port numbers. Please also refer to the included disk for more examples and details on
NAT.

7.5.3 Example 3: Multiple Public IP Addresses With Inside Servers
In this example, there are 3 IGAs from our ISP. There are many departments but two have their own FTP
server. All departments share the same router. The example will reserve one IGA for each department with
an FTP server and all departments use the other IGA. Map the FTP servers to the first two IGAs and the
other LAN traffic to the remaining IGA. Map the third IGA to an inside web server and mail server. Four
rules need to be configured, two bi-directional and two uni-directional as follows.
Rule 1.
Map the first IGA to the first inside FTP server for FTP traffic in both directions (1 : 1
mapping, giving both local and global IP addresses).
Rule 2.
Map the second IGA to our second inside FTP server for FTP traffic in both directions (1 : 1
mapping, giving both local and global IP addresses).
Rule 3.
Map the other outgoing LAN traffic to IGA3 (Many : 1 mapping).
Rule 4.
You also map your third IGA to the web server and mail server on the LAN. Type Server
allows you to specify multiple servers, of different types, to other computers behind NAT on the
LAN.
The example situation looks somewhat like this:

Sets. Therefore you must choose the Full Feature option from the Network Address
Translation field (in menu 4 or menu 11.3) in The following figure shows how to configure the
first rule .
Step 2.
Then enter 15 from the main menu.
Step 3.
Enter 1 to configure the Address Mapping Sets.
Step 4.
Enter 1 to begin configuring this new set. Enter a Set Name, choose the Edit Action and then
enter 1 for the Select Rule field. Press [ENTER] to confirm.
Step 5.
Select Type as One-to-One (direct mapping for packets going both ways), and enter the local
Start IP as 192.168.1.10 (the IP address of FTP Server 1), the global Start IP as 10.132.50.1

7.5.4 Example 4: NAT Unfriendly Application Programs
Some applications do not support NAT Mapping using TCP or UDP port address translation. In this case it
is better to use Many-to-Many No Overload mapping as port numbers do not change for Many-toMany No Overload (and One-to-One) NAT mapping types. The following figure illustrates this.
Figure 7-21 NAT Example 4

Other applications such as some gaming programs are NAT unfriendly because
they embed addressing information in the data stream. These applications won’t
work through NAT even when using One-to-One and Many-to-Many No Overload
mapping types.

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 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, for example, 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.

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.
Filter Configuration
8-3
Prestige 650H ADSL Router
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, for example, 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.

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 two types of filter rules: TCP/IP and Generic. Depending on the type of rule, the parameters for
each 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, for instance, 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.
8.3.1 TCP/IP Filter Rule
This section shows you how to configure a TCP/IP filter rule. TCP/IP rules allow you to base the rule on
the fields in the IP and the upper layer protocol, for example, UDP and TCP headers.
To configure TCP/IP rules, select TCP/IP Filter Rule from the Filter Type field and press [ENTER] to
open Menu 21.1.1 – TCP/IP Filter Rule, as shown next.

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 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 fields are specified in hexadecimal numbers. Note that it takes
two hexadecimal digits to represent a byte, so if the length is 4, the value in either field will take 8 digits,
for example, FFFFFFFF.
To configure a generic rule select an empty filter set in menu 21, for example 5. Select Generic Filter
Rule in the Filter Type field and press [ENTER] to open Menu 21.5.1 – Generic Filter Rule, as shown in
the following figure.

Filter Types and NAT
There are two classes of filter rules, Generic Filter Device rules and Protocol Filter (TCP/IP) rules.
Generic Filter rules act on the raw data from/to LAN and WAN. Protocol Filter rules act on IP packets.
When NAT (Network Address Translation) is enabled, the inside IP address and port number are replaced
on a connection-by-connection basis, which makes it impossible to know the exact address and port on the
wire. Therefore, the Prestige applies the protocol filters to the “native” IP address and port number before
NAT for outgoing packets and after NAT for incoming packets. On the other hand, the generic (or device)
filters are applied to the raw packets that appear on the wire. They are applied at the point where the
Prestige is receiving and sending the packets; for instance, the interface. The interface can be an Ethernet,
or any other hardware port. The following figure illustrates this.

SNMP Configuration
This chapter explains SNMP Configuration menu 22.
SNMP is only available if TCP/IP is configured.
9.1
About SNMP
Simple Network Management Protocol is a protocol used for exchanging management information between
network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP agent
functionality, which allows a manager station to manage and monitor the Prestige through the network. The
Prestige supports SNMP version one (SNMPv1). The next figure illustrates an SNMP management
operation. SNMP is only available if TCP/IP is configured.
Figure 9-1 SNMP Management Model
SNMP Configuration
9-1
Prestige 650H ADSL Router
An SNMP managed network consists of two main components: agents and a manager.
An agent is a management software module that resides in a managed device (the Prestige). An agent
translates the local management information from the managed device into a form compatible with SNMP.
The manager is the console through which network administrators perform network management functions.
It executes applications that control and monitor managed devices.
The managed devices contain object variables/managed objects that define each piece of information to be
collected about a device. Examples of variables include such as number of packets received, node port
status etc. A Management Information Base (MIB) is a collection of managed objects. SNMP allows a
manager and agents to communicate for the purpose of accessing these objects.
SNMP itself is a simple request/response protocol based on the manager/agent model. The manager issues a
request and the agent returns responses using the following protocol operations:
•
Get - Allows the manager to retrieve an object variable from the agent.
•
GetNext - Allows the manager to retrieve the next object variable from a table or list within an agent.
In SNMPv1, when a manager wants to retrieve all elements of a table from an agent, it initiates a Get
operation, followed by a series of GetNext operations.
•
Set - Allows the manager to set values for object variables within an agent.
•
Trap - Used by the agent to inform the manager of some events.
9.2
Supported MIBs
The Prestige supports RFC-1215 and MIB II as defined in RFC-1213. The focus of the MIBs is to let
administrators collect statistic data and monitor status and performance.
9.3
SNMP Configuration
To configure SNMP, select option 22 from the main menu to open Menu 22 — SNMP Configuration as

Chapter 11
Firmware and Configuration File
Maintenance
This chapter tells you how to backup and restore your configuration file as well as upload new
firmware and configuration files.
11.1 Filename Conventions
The configuration file (often called the romfile or rom-0) contains the factory default settings in the menus
such as password, DHCP Setup, TCP/IP Setup, etc. It arrives from ZyXEL with a rom filename extension.
Once you have customized the Prestige's settings, they can be saved back to your computer under a
filename of your choosing.
ZyNOS (ZyXEL Network Operating System sometimes referred to as the “ras” file) is the system firmware
and has a “bin” filename extension. With many ftp and tftp clients, the filenames are similar to those seen
next.
ftp> put firmware.bin ras
This is a sample ftp session showing the transfer of the computer file " firmware.bin" to the Prestige.
ftp> get rom-0 config.cfg
This is a sample ftp session saving the current configuration to the computer file config.cfg.
If your [t]ftp client does not allow you to have a destination filename different than the source, you will
need to rename them as the Prestige only recognizes “rom-0” and “ras”. Be sure you keep unaltered copies
of both files for later use.
The following table is a summary. Please note that the internal filename refers to the filename on the
Prestige and the external filename refers to the filename not on the Prestige, that is, on your computer, local
network or ftp site and so the name (but not the extension) will vary. After uploading new firmware see the
ZyNOS F/W Version field in Menu 24.2.1 - System Maintenance - Information to confirm that you
have uploaded the correct firmware version.

The Prestige supports the up/downloading of the firmware and the configuration file using TFTP (Trivial
File Transfer Protocol) over LAN. Although TFTP should work over WAN as well, it is not recommended.
To use TFTP, your computer must have both telnet and TFTP clients. To backup the configuration file,
follow the procedure shown next:
Step 1.
Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not
have any security checks, the Prestige records the IP address of the telnet client and accepts
TFTP requests only from this address.
Step 2.
Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.

To use TFTP, your computer must have both telnet and TFTP clients. To transfer the firmware and the
configuration file, follow the procedure shown next:
Step 1.
Use telnet from your computer to connect to the Prestige and log in. Because TFTP does not
have any security checks, the Prestige records the IP address of the telnet client and accepts
TFTP requests only from this address.
Step 2.
Put the SMT in command interpreter (CI) mode by entering 8 in Menu 24 – System
Maintenance.
Step 3.
Enter the command “sys stdio 0” to disable the SMT timeout, so the TFTP transfer will not be
interrupted. Enter command “sys stdio 5” to restore the five-minute SMT timeout (default) when
the file transfer is complete.
Step 4.
Launch the TFTP client on your computer and connect to the Prestige. Set the transfer mode to
binary before starting data transfer.
Step 5.
Use the TFTP client (see the example below) to transfer files between the Prestige and the
computer. The file name for the firmware is “ras” and the configuration file is “rom-0” (romzero, not capital o).
Note that the telnet connection must be active and the SMT in CI mode before and during the TFTP
transfer. For details on TFTP commands (see following example), please consult the documentation of your
Firmware and Configuration File Maintenance
11-9
Prestige 650H ADSL Router
TFTP client program. For UNIX, use “get” to transfer from the Prestige to the computer, “put” the other
way around, and “binary” to set binary transfer mode.
11.4.5 Example: TFTP Command
The following is an example tftp command:
TFTP [-i] host put firmware.bin ras
where “i” specifies binary image transfer mode (use this mode when transferring binary files), “host” is the
Prestige’s IP address, “put” transfers the file source on the computer (firmware.bin – name of the firmware
on the computer) to the file destination on the remote host (ras - name of the firmware on the Prestige).
Commands that you may see in third party TFTP clients are listed earlier in this chapter.
TFTP over WAN will not work if you have applied a filter in menu 11.5 (WAN) to block Telnet service.

Chapter 13
IP Policy Routing
This chapter covers setting and applying policies used for IP routing.
13.1 Introduction
Traditionally, routing is based on the destination address only and the IAD takes the shortest path to
forward a packet. IP Routing Policy (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.
13.2 Benefits
•
Source-Based Routing – Network administrators can use policy-based routing to direct traffic from
different users through different connections.
•
Quality of Service (QoS) – Organizations can differentiate traffic by setting the precedence or TOS
(Type of Service) values in the IP header at the periphery of the network to enable the backbone to
prioritize traffic.
•
Cost Savings – IPPR allows organizations to distribute interactive traffic on high-bandwidth, high-cost
paths while using low-cost paths for batch traffic.
•
Load Sharing – Network administrators can use IPPR to distribute traffic among multiple paths.
13.3 Routing Policy
Individual routing policies are used as part of the overall IPPR process. A policy defines the matching
criteria and the action to take when a packet meets the criteria. The action is taken only when all the criteria
are met. The criteria includes the source address and port, IP protocol (ICMP, UDP, TCP, etc.), destination
address and port, TOS and precedence (fields in the IP header) and length. The inclusion of length criterion
is to differentiate between interactive and bulk traffic. Interactive applications, for example, telnet, tend to
have short packets, while bulk traffic, for example, file transfer, tends to have large packets.
The actions that can be taken include:
•
routing the packet to a different gateway (and hence the outgoing interface).
•
setting the TOS and precedence fields in the IP header.
IP Policy Routing
13-1
Prestige 650H ADSL Router
IPPR follows the existing packet filtering facility of RAS in style and in implementation. The policies are
divided into sets, where related policies are grouped together. A user defines the policies before applying
them to an interface or a remote node, in the same fashion as the filters. There are 12 policy sets with six
policies in each set.
13.4 IP Routing Policy Setup

Call Scheduling
Call scheduling (applicable for PPP or PPPoE encapsulation only) allows you to dictate when a
remote node should be called and for how long.
14.1 Introduction
The call scheduling feature allows the Prestige to manage a remote node and dictate when a remote node
should be called and for how long. This feature is similar to the scheduler in a video cassette recorder (you
can specify a time period for the VCR to record). You can apply up to 4 schedule sets in Menu 11.1 —

Appendix A
PPPoE
PPPoE in Action
An ADSL modem 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 (see the next figure). One PVC can support any number of PPP sessions from your LAN.
PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
Benefits of PPPoE
PPPoE offers the following benefits:
1.
It provides you with a familiar dial-up networking (DUN) user interface.
2.
It lessens the burden on the carriers of provisioning virtual circuits all the way to the ISP on multiple
switches for thousands of users. For GSTN (PSTN and ISDN), the switching fabric is already in place.
3.
It allows the ISP to use the existing dial-up model to authenticate and (optionally) to provide
differentiated services.
Traditional Dial-up Scenario
The following diagram depicts a typical hardware configuration where the PCs use traditional dial-up
networking.
Diagram 1 Single-PC per Router Hardware Configuration
PPPoE
A
Prestige 650H ADSL Router
How PPPoE Works
The PPPoE driver makes the Ethernet appear as a serial link to the PC and the PC runs PPP over it, while the
modem bridges the Ethernet frames to the Access Concentrator (AC). Between the AC and an ISP, the AC is
acting as a L2TP (Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator) and tunnels the PPP
frames to the ISP. The L2TP tunnel is capable of carrying multiple PPP sessions.
With PPPoE, the VC (Virtual Circuit) is equivalent to the dial-up connection and is between the modem and
the AC, as opposed to all the way to the ISP. However, the PPP negotiation is between the PC and the ISP.
Prestige as a PPPoE Client
When using the Prestige as a PPPoE client, the PCs on the LAN see only Ethernet and are not aware of
PPPoE. This alleviates the administrator from having to manage the PPPoE clients on the individual PCs.

Virtual Circuit Topology
ATM is a connection-oriented technology, meaning that it sets up virtual circuits over which end systems
communicate. The terminology for virtual circuits is as follows:
•
Virtual Channel
Logical connections between ATM switches
•
Virtual Path
A bundle of virtual channels
•
Virtual Circuit
A series of virtual paths between circuit end points
Diagram 3 Virtual Circuit Topology
Think of a virtual path as a cable that contains a bundle of wires. The cable connects two points and wires
within the cable provide individual circuits between the two points. In an ATM cell header, a VPI (Virtual
Path Identifier) identifies a link formed by a virtual path; a VCI (Virtual Channel Identifier) identifies a
channel within a virtual path.
The VPI and VCI identify a virtual path, that is, termination points between ATM switches. A series of
virtual paths make up a virtual circuit.
Your service provider should supply you with VPI/VCI numbers.
