configuration.
See the table below
for a description of the
parameters.
Note: If you check “Enabled” and specify an IP address of 0.0.0.0, any
host can manage the Modem.
For remote management via WAN IP address you need to connect
using port 8080. Simply enter WAN IP address followed by :8080 in the
address field of your web browser, for example, 123.123.123.123:8080.
This applies unless you change the port setting, in which case you

Disable: Disables the connection.
1483 Bridging: Bridging is a standardized layer
2 technology. It is typically used in corporate
networks to extend the physical reach of a single
LAN segment and increase the number of stations
on a LAN without compromising performance.
Bridged data is encapsulated using the RFC1483
protocol to enable data transport.
•
•
PPPoA: Point-to-Point Protocol over ATM is a
method of encapsulating data for transmission to
a far point.
1483 Routing: 1483 Routing allows a simple, low-
cost connection to the Internet via a standard
Ethernet port. The Modem looks up the network
address for each packet seen on the LAN port. If
the address is listed in the routing table as local, it
is filtered. If the address is listed under the ADSL
port, it is forwarded. Or if the address is not found,
then it is automatically forwarded to the default
Modem (i.e., the Modem at the head end).
When you have finished
entering your connection parameters, click “SAVE SETINGS”. You
can verify that you have established an ADSL connection by clicking
Status at the bottom of the left-hand menu.
See the table for a description of the parameters.
•
•
PPPoE: Point-to-Point over Ethernet is a common
connection method used for xDSL.
MAC Encapsulated Routing: If your ADSL service
is a Bridged mode service and you want to share
the connection to multiple PC’s, please select
MAC Encapsulated Routing. MER is a protocol
that allows you do IP routing with NAT enabled.
VPI/VCI
See Virtual Path Identifier (VPI) and Virtual Circuit
Identifier (VCI). Data flows are broken up into fixed
length cells, each of which contains a Virtual Path
Identifier (VPI) that identifies the path between two
nodes, and a Virtual Circuit Identifier (VCI) that
identifies the data channel within that virtual path.
Each virtual circuit maintains a constant flow of
cells between the two end points. When there is
no data to transmit, empty cells are sent. When
data needs to be transmitted, it is immediately
inserted into the cell flows.

Address Mapping
Special Applications
Use Address Mapping to
allow a limited number of
public IP addresses to be
translated into multiple
private IP addresses for
use on the internal LAN
network. This also hides
the internal network for
increased privacy and
security.
Some applications, such
as Internet gaming,
video conferencing,
Internet telephony and
others, require multiple
connections. These
applications cannot work
with Network Address
Translation (NAT) enabled.
If you need to run
applications that require
multiple connections,
use the following screen
to specify the additional
public ports to be opened for each application.
Port Forwarding
Specify the public port number normally associated with an
application in the Trigger Port field. Set the protocol type to TCP
or UDP, and then enter the ports that the application requires. The
ports may be in the format 7, 11, 57, or in a range, e.g., 72-96, or a
combination of both, e.g., 7, 11, 57, 72-96.
If you configure the Port
Forwarding settings,
remote users accessing
services such as web
or FTP at your local site
via public IP addresses
Popular applications
requiring multiple ports
are listed in the Popular
Applications field. From
the drop-down list, choose
the application and then
choose a row number to
copy this data into.
can be automatically
redirected to local servers
configured with private
IP addresses. In other
words, depending on
the requested service
(TCP/UDP port number),
the Modem redirects the
external service request to the appropriate server (located at another
internal IP address).
Note: Choosing a row
that already contains data
will overwrite the current
settings.
For example, if you set Type/Public Port to TCP/80 (HTTP or web)
and the LAN IP Address/LAN Port to 10.1.1.3/80, then all HTTP
requests from outside users will be transferred to 10.1.1.3 on port 80.
Therefore, by just entering the IP address provided by the ISP, Internet
users can access the service they need at the local address to which
you redirect them.
The more common TCP service ports include:
HTTP: 80, FTP: 21, Telnet: 23, and POP3: 110.

Static Route Parameters
Static routing is the manual method used to set up routing. A network
administrator enters routes into the Modem using the following
screens. This method has the advantage of being predictable, and
simple to set up. It is easy to manage in small networks but does not
scale well.

Parameter
Description
Flags
Indicates the route status:
C = Direct connection on the same subnet.
S = Static Modem
R = RIP (Routing Information Protocol) assigned
route.
RIP sends routing-update messages at regular intervals and when
the network topology changes. When a Modem receives a routing
update that includes changes to an entry, it updates its routing table
to reflect the new route. RIP Modems maintain only the best route to
a destination. After updating its routing table, the Modem immediately
begins transmitting routing updates to inform other network Modems
of the change.
I = ICMP (Internet Control Message Protocol)
Redirect route.
Network
Address
Destination IP address
Netmask
The subnetwork associated with the destination.
This is a template that identifies the address bits
in the destination address used for routing to
specific subnets. Each bit that corresponds to a
“1” is part of the subnet mask number; each bit
that corresponds to “0” is part of the host number.
Gateway
Interface
Metric
The IP address of the Modem at the next hop to
which frames are forwarded.
The local interface through which the next hop of
this route is reached.
When a Modem receives a routing update that
contains a new or changed destination network
entry, the Modem adds 1 to the metric value
indicated in the update and enters the network in
the routing table.

Intrusion Detection
The Modem’s firewall
inspects packets at
the application layer,
maintains TCP and UDP
session information
including timeouts and
number of active sessions,
and provides the ability to
detect and prevent certain
types of network attacks
such as Denial-of-Service
(DoS) attacks.
From the Access Control Page, Add PC section, check the option for
“WWW with URL Blocking” in the Client PC Service table to filter out
the web sites and keywords selected below, on a specific PC.
The Modem allows the user to block access to web sites from a
particular PC by entering either a full URL address or just a keyword.
This feature can be used to protect children from accessing violent or
pornographic web sites.

Network attacks that deny
access to a network device
are called DoS attacks.
DoS attacks are aimed
at devices and networks
with a connection to the
Internet. Their goal is not
to steal information, but
to disable a device or
network so users no longer
have access to network
resources.
Stateful Packet
Inspection
This option allows you to select
different application types that are
using dynamic port numbers. If you
wish to use Stateful Packet Inspection
(SPI) for blocking packets, click on the
Yes radio button in the “Enable SPI and
Anti-DoS firewall protection” field and
then check the inspection type that you
need, such as Packet Fragmentation,
TCP Connection, UDP Session, FTP
Service, H.323 Service, and TFTP
Service. It is called a “Stateful” packet
inspection because it examines the
contents of the packet to determine
the state of the communication; i.e.,
it ensures that the stated destination
computer has previously requested the
current communication. This is a way
of ensuring that all communications are
initiated by the recipient computer and
are taking place only with sources that
are known and trusted from previous
interactions. In addition to being more
rigorous in their inspection of packets,
stateful inspection firewalls also
close off ports until a connection to
the specific port is requested. When
particular types of traffic are checked,
only the particular type of traffic
initiated from the internal LAN will be
allowed. For example, if the user only
checks FTP Service in the Stateful
Packet Inspection section, all incoming
traffic will be blocked except for FTP
connections initiated from the local
LAN.
The Modem protects
against DoS attacks
including: Ping of Death
(Ping flood) attack, SYN
flood attack, IP fragment
attack (Teardrop Attack),
Brute-force attack, Land
Attack, IP Spoofing
attack, IP with zero length,
TCP null scan (Port
Scan Attack), UDP port
loopback, Snork Attack.
Note: The firewall does not
significantly affect system
performance, so we advise
enabling the prevention
features to protect your
network.
Parameter

UPnP
Statistics
(Superframes represent the highest level of data
presentation.
UPnP (Universal Plug-and-
Play) is a technology that
offers seamless operation
of voice messaging, video
messaging, games, and
other applications that
are UPnP-compliant.
Some applications require
the Modem’s firewall
to be configured in a
specific way to operate
properly. This usually
requires opening TCP
and UDP ports, and in
some instances, setting trigger ports. An application that is UPnP
compliant has the ability to communicate with the Modem, basically
“telling” the Modem which way it needs the firewall configured. The
Modem ships with the UPnP feature disabled. If you are using any
applications that are UPnP-compliant, and wish to take advantage
of the UPnP features, you can enable the UPnP feature. Click on the
“Enable” button then click on the “SAVE SETTINGS” button to save
your settings.
Each superframe contains regular ADSL frames,
one of which is used to provide superframe
synchronization, identifying the start of a

PTC General Warning
The grant of a Telepermit for any item of terminal equipment indicates
only that Telecom has accepted that the item complies with minimum
conditions for connection to its network. It indicates no endorsement
of the product by Telecom, nor does it provide any sort of warranty.
Above all, it provides no assurance that any item will work correctly in
all respects with another item of Telepermitted equipment of a different
make or model, nor does it imply that any product is compatible with
all of Telecom’s network services.
This Belkin F5D5730au ADSL Router on Long Lines
This Belkin F5D5730au ADSL Router may not achieve the type of
“high speed” operation expected when attached to a line that is
longer than intended by the ITU-T ADSL standard i.e. >3 km of 0.4mm
cable or a shorter cable length with several tails or multiples. If the
Router is installed in such conditions and does not give the expected
performance do not refer the matter to the Telecom Fault Service.
The Service Covered by These Telepermits
This Telepermit shows that this Belkin F5D5730au ADSL Router is
suitable for connection to Telecom’s existing ADSL1 service. This
service is defined by the specification PTC270. When compliance with
the specification is proved a PTC272 Telepermit is issued for each
product. This Telepermit does not show suitability for connection to a
new ADSL2 service when Telecom introduces it. Telecom will require
proof of compliance with a new PTC specification when the new
ADSL2 service is introduced. This note should be attached to each of
the boxes containing these Belkin F5D5730au ADSL Routers:
ADSL2 & ADSL2+ Services
ADSL2 and ADSL2+ services are only available from the network
of the ADSL Service Provider. Telecom does not currently provide
either of the services to customers from its Broadband network.
When Telecom introduces either ADSL2 and/or ADSL2+ service this
Belkin F5D5730au ADSL Router will have to prove itself suitable for
connection to the service.
