information to computers on a network.

When you enable DHCP on a network, you allow a device ­such as your ADSL/Ethernet router or a router located with your
ISP - to assign temporary IP addresses to your computers
whenever they connect to your network. The assigning device
is called a DHCP server, and the receiving device is a DHCP
client.

IP information based on your ISP settings.

21 / 97

jetSpeed 520+ User’s Manual

An IP address pool typically includes a range private addresses
that you define. LAN administrators often define private IP
addresses for use only on their networks. You can also use
DHCP server pools to distribute multiple public IP addresses, if,
for example, these are to be shared among a larger set of LAN
computers.

You can create up to two DHCP server address pools. You can
define a single pool with addresses that can be assigned to
your LAN PCs (connected via the Ethernet port) and to a
USB-connected computer, as long you have assigned to the
USB and Ethernet interfaces static IP addresses that place
them in the same subnet.

 Start/End IP Addresses: Specify the lowest and highest

addresses in the pool, up to a maximum range of 254
addresses.

 Mac Address: A MAC address is a manufacturer-assigned

hardware ID that is unique for each device on a network.
Use this field only if you want to assign a specific IP
address to a specific computer (that is, you are creating an
exception to the dynamic assignment of addresses). The IP
address you specify will be assigned to the computer that
corresponds to this MAC address. If you type a MAC
address here, you must have specified the same IP
address in both the Start IP Address and End IP Address
fields.

 Net Mask: Specifies which portion of each IP addresses in

this range refers to the network and which portion refers to
the host (computer). You can use the net mask to
distinguish which pool of addresses should be distributed to
a particular subset of computers on your LAN (call a
subnet).

 Domain Name: A user-friendly name that refers to the

subnet that includes the addresses in this pool.

 Gateway Address: The address of the default gateway for

computers that receive IP addresses from this pool. If no
value is specified, then the appropriate LAN (eth-0) or USB
(usb-0) port address on the device will be distributed to
each PC as its gateway address, depending on how each
is connected. See Configuring IP Routes for an explanation
of gateway addresses.

22 / 97

jetSpeed 520+ User’s Manual

 DNS/SDNS: The IP address of the Domain Name System

server to be used by computers that receive IP addresses
from this pool. The DNS translates common Internet names
that you type into your web browser into their equivalent
numeric IP addresses. Typically, this server is located with
your ISP.

 SMTP...SWINS (optional): The IP addresses of devices

that perform various services for computers that receive IP
addresses from this pool (such as the SMTP, or Simple
Mail Transfer Protocol, server which handles e-mail traffic).
Contact your ISP for these addresses.

 Click on the Submit button when completed and make sure

to Commit & Reboot.

5.4 DHCP Relay

Click on the DHCP Relay link to view the DHCP Relay settings.

Some ISPs perform the DHCP server function for their
customers' home/small office networks. In this case, you can
configure the device as a DHCP relay agent. When a computer
on your network requests Internet access, the ADSL/Ethernet
router connects your ISP to obtain an IP address and other
information, and then forwards that information to the computer.

Fill in the DHCP server IP address in the text boxes and select
an interface name from the dorp down list, then click on the
Add button.

The devices WAN-side interfaces are used to communication
via the DSL port. A WAN interface comprises two layers: a
lower-level ATM VC interface and a higher-level protocol
interface:

The ATM VC interface enables the device to communicate
using the Asynchronous Transfer Mode protocol. The ATM
protocol provides a common format for transmitting data over a
variety of hardware systems that make up the backbone of the
Internet. The virtual circuit (VC) properties of the ATM VC
interface identify a unique path that your ADSL/Ethernet router
uses to communicate via the ATM-based network with the
telephone company central office equipment.

The higher-level protocol interface(s) operate "on top" of the
ATM VC interface. The higher-level interface handles the
protocols needed to log onto and exchange data with the ISP's
access server. ISPs can use several different protocols,
including the Point-to-Point Protocol (PPP), Ethernet-over-ATM
(EoA) protocol, or the Internet Protocol-over-ATM (IPoA). Be
sure to create the specific type of WAN interface your ISP
requires.

After you have defined the ATM VC properties as described in
this topic, you can configure one of the higher level WAN
interfaces to enable communication with your ISP.

After you click on the Add button, another window will appear.

27 / 97

jetSpeed 520+ User’s Manual

 VC Interface: The name of the lower-level interface on

which this VC operates. The low-level interface names are
preconfigured in the software and identify the type of traffic
that can be supported, such as data or voice. Internet data
services typically use an AAL5-type interface.

 VPI, VCI, and Mux Type: These settings identify a unique

ATM data path for communication between your
ADSL/Ethernet router and your ISP.

 Max Proto per AAL5: If you are using an AAL5-type

of interface, this setting indicates the number of higher level
interfaces that the VC can support (the higher level
interfaces can be PPP, EoA, or IPoA interfaces). Contact
your ISP to determine which connection protocol(s) they
require.

The Point-to-Point Protocol (PPP) is one of several protocols
used to enable communication between ISPs and their
customers. PPP performs tasks such as the following:

 Identifying the type of service the ISP provides to a given

customer

 Identifying the customer to the ISP through a username

and password login

 Enabling the ISP to assign Internet information to the

customer's computers

PPP can be used only when your connection with your ISP is a
routed connection, not with a bridged connection.

 PPP Interface: The predefined name of the PPP interface.
 ATM VC: The Virtual Circuit over which this PPP data is

sent. The VC identifies the physical path the data takes to
reach your ISP. See Configuring the ATM VC for more
information.

 Interface Sec Type: The type of Firewall protections that

are in effect on the interface (public, private, or DMZ): A
public interface connects to the Internet (PPP interfaces are
typically public). Packets received on a public interface are

30 / 97

jetSpeed 520+ User’s Manual

subject to the most restrictive set of firewall protections
defined in the software. A private interface connects to your
LAN, such as the Ethernet interface. Packets received on a
private interface are subject to a less restrictive set of
protections, because they originate within the network. The
term DMZ (de-militarized zone), in Internet networking
terms, refers to computers that are available for both public
and in-network accesses (such as a company's public Web
server). Packets incoming on a DMZ interface -- whether
from a LAN or external source -- are subject to a set of
protections that is in between public and private interfaces
in terms of restrictiveness.

 Protocol: The type of PPP protocol used. Your ISP may

use PPP-over-Ethernet (PPPoE) or PPP-over-ATM
(PPPoA).

 Default Route: Indicates whether the ADSL/Ethernet router

should use the IP address assigned to this connection as
its default route. Can be Enabled or Disabled. See
Configuring IP Routes for an explanation of default routes.

6.4 Ethernet over ATM (EoA)

Click on the EOA link to view the RFC1483/EoA configuration
table. This table displays EoA information such as: interface
name, interface security type, lower interface, config IP,
network IP, DHCP, default route, gateway IP, and status.

Click on the trash can icon to delete the current interface, or
edit the current interface by clicking on the pencil icon.

Click on the Add button to add another interface.

The Ethernet-over-ATM (EoA) protocol is commonly used to
carry data between local area networks that use the Ethernet
protocol and wide-area networks that use the ATM protocol.
Many telecommunications industry networks use the ATM
protocol. ISPs who provide DSL services often use the EoA
protocol for data transfer with their customers' DSL modems.

EoA can be implemented to provide a bridged connection
between a DSL modem and the ISP. In a bridged connection,
data is shared between the ISP's network and their customer's
as if the networks were on the same physical LAN. Bridged
connections do not use the IP protocol. EoA can also be
configured to provide a routed connection with the ISP, which
uses the IP protocol to exchange data.

9.2 RIP

Click on the RIP link to view the Routing Information Protocol
(RIP) Configuration table. Routers on your LAN communicate
with one another using the Routing Information Protocol.

RIP is an Internet protocol you can set up to share routing table
information with other routing devices on your LAN, at your
ISP's location, or on remote networks connected via the ADSL
line. Generally, RIP is used to enable communication on
autonomous networks. An autonomous network is one in which
all the computers are administered by the same entity. An
autonomous network may be a single network, or a grouping of
several networks under the same administration. An example of
an autonomous network is a corporate LAN, including devices
that can access it from remote locations, such as the computers
telecommuters use.

Using RIP, each device sends its routing table to its closest
neighbour every 30 seconds. The neighbouring device in turn
passes the information on to its next neighbour and so on until
all devices in the autonomous network have the same set of
routes.

This table lists any interfaces on your device that use RIP
(typically the LAN interface), and the version of the protocol
used. Click on the trashcan icon to delete a RIP interface. Click
on the Global Stats icon to view the NAT statistics. This table
will open in a new window.

 RIP Status: Select the Enable or Disable radio button in

order to use the protocol.

 Age: This s the amount of time in seconds that the device's

RIP table will retain each route that it learns from adjacent
computers.

 Update Time: This specifies how frequently the

ADSL/Ethernet router will send out its routing table to its
neighbours.

 IF Name: Select an interface name from the drop-down list.
 Metric: Enter a metric value. RIP uses a hop count as a

way to determine the best path to a given destination in the
network. The hop count is the sum of the metric values
assigned to each port through which data is passed before
reaching the destination. Among several alternative routes,
the one with the lowest hop count is considered the fastest
path. For example, if you assign this port a metric of 1, then
RIP will add 1 to the hop count when calculating a route
that passes through this port. If you know that
communication via this interface is slower than through
other interfaces on your network, you can assign it a higher
metric value than the others. You can select any integer
from 1 to 15.

 Send/Receive Mode: Select a Send and Receive mode

from the drop-down list. The Send Mode setting indicates
the RIP version this interface will use when it sends its
route information to other devices. The Receive Mode
setting indicates the RIP version(s) in which information
must be passed to the ADSL/Ethernet router in order for it
to be accepted into its routing table. RIP version 1 is the
original RIP protocol. Select RIP1 if you have devices that
communicate with this interface that understand RIP
version 1 only. RIP version 2 is the preferred selection
because it supports "classless" IP addresses (which are
used to create subnets) and other features. Select RIP2 if
all other routing devices on your LAN support this version
of the protocol.

following Denail of Service protection: SYN DoS, ICMP
DoS, Per-host DoS protection.

 Max Half open TCP Connection: Enter the percentage of

concurrent IP sessions that can be in the half-open state. In
ordinary TCP communication, packets are in the half-open
state only briefly as a connection is being initiated; the state
changes to active when packets are being exchanged, or
closed when the exchange is complete. TCP connections in
the half-open state can use up the available IP sessions. If
the percentage is exceeded, then the half-open sessions
will be closed and replaced with new sessions as they are
initiated.

 MAX ICMP Connection: Sets the percentage of concurrent

IP sessions that can be used for ICMP messages. If the
percentage is exceeded, then older ICMP IP sessions will

9.4 IP Filter

Click on the IP Filter link to view the IP filter configuration table. The
IP filter feature enables you to create rules that control the
forwarding of incoming and outgoing data between your LAN and the
Internet and within your LAN.

You can create IP filter rules to block attempts by certain computers
on your LAN to access certain types of data or Internet locations.
You can also block incoming access to computers on your LAN.

When you define an IP filter rule and enable the feature, you instruct
the ADSL/Ethernet router to examine data packets to determine
whether they meet criteria set forth in the rule. The criteria can
include the network or internet protocol the packet carries, the
direction in which it is travelling (for example, from the LAN to the
Internet or vice versa), the IP address of the sending computer, the
destination IP address, and other characteristics of the packet data.

If the packet matches the criteria established in a rule, the packet
can either be accepted (forwarded towards its destination), or denied
(discarded), depending on the action specified in the rule.

 Security Level: Select None, Medium, Low, or High.

This setting determines which IP Filter rules take effect,
based on the security level specified in each rule. For
example, when High is selected, only those rules that are
assigned a security value of High will be in effect. The
same is true for the Medium and Low settings. When
None is selected, IP Filtering is disabled.

 Private/Public/DMZ Default Action: This setting specifies

a default action to be taken (Accept or Deny) on private,
public, or DMZ-type device interfaces when they receive
packets that do not match any of the filtering rules. You can
specify a different default action for each interface type. A

public interface typically connects to the Internet. PPP,
EoA, and IPoA interfaces are typically public. Packets
received on a public interface are subject to the most
restrictive set of firewall protections defined in the software.
Typically, the global setting for public interfaces is Deny, so
that all accesses to your LAN initiated from external
computers are denied. A private interface connects to your
LAN, such as the Ethernet interface. Packets received on a
private interface are subject to a less restrictive set of
protections, because they originate within the network.
Typically, the global setting for private interfaces is Accept,
so that LAN computers have access to the ADSL/Ethernet
routers' Internet connection. The term DMZ (de-militarized
zone), in Internet networking terms, refers to computers
that are available for both public and in-network accesses
(such as a company's public Web server). Packets
received on a DMZ interface -- whether from a LAN or
external source -- are subject to a set of protections that is
in between public and private interfaces in terms of
restrictiveness. The global setting for DMZ-type interfaces
may be set to Deny so that all attempts to access these
servers are denied by default; the administrator may then
configure IP Filter rules to allow accesses of certain types.

9.5 Bridge Filter

Click on the Bridge Filter link to view the bridge filter
configuration table. Bridge filter rules can be created to control
the forwarding of incoming and outgoing data between your
LAN and the Internet and within your LAN. Bridge filter rules
make decisions based on the structure of the "layer 2" data
packets (e.g., Ethernet packets) received on the device
interfaces, unlike IP filter rules, which are based on the
structure of "layer 3" (e.g., IP) packets.

When the bridge filtering feature is enabled, the bridge/router
examines each incoming layer 2 packet and compares it to the
bridge filter rules. The bridge filter rules specify which bits of the
packet are to be examined, and what criteria those bits must
meet in order to qualify as a match for the rule.

1020) so that you leave enough room between them for
inserting new rules if necessary.

 Interface: Enter the interface name on which the rule will

take effect.

 Direction:

Specifies whether the rule should apply to

packets that are incoming or outgoing on the selected
interface. Incoming refers to packets coming in to the LAN
on the interface, and Outgoing refers to packets going out
from the LAN. You can use rules that specify the incoming
direction to restrict external computers from accessing your
LAN.

 In Interface: The interface from which packets must

be forwarded in order for this rule to be invoked. For
example, if the Interface criteria is set to ppp-0, then the In
Interface could be set to usb-0. This specifies that the rule
applies only to packets passed from the USB computer
through the router's PPP interface. This option is valid only
for rules defined for the outgoing direction.

 Action: Specifies what the rule will do to a packet when the

packet matches the rule criteria. The action can be Accept
(forward to destination) or Deny (discard the packet). Do
not select the CallMgt option.

 Log Option: When Enabled is selected, a log entry will be

created on the system each time this rule is invoked.
Logging may be helpful when troubleshooting. You can
also disable logging, log only packets that match rules, or
log only packets that do not match rules.

9.8 DDNS

Click on the DDNS link to configure and add dynamic DNS
entries. Dynamic DNS (DDNS) is a service that facilitates
outside Internet access to a LAN host even when the host's
dynamically-assigned IP address changes frequently.

DDNS is useful when you have a host (running for example, a
web server) that receives a dynamically assigned IP address
from a DHCP server. A user on the Internet would typically
access the host by entering its name in their web browser. A
DNS server on the web would then resolve the name to its
associated numeric IP address, as required for Internet protocol
processing. However, when a host's IP address is dynamically
assigned (for example, by a DHCP server), it may change
frequently. In this scenario, a DNS server may have outdated
data and may not be able to resolve a host name to the current
IP address.

When a host is registered with a DDNS service provider, the
provider is automatically notified by the host of any change in
its IP address and the provider then propagates the change
throughout the DNS server system.

Click on the Add Service button to a new DDNS entry.

 Interface: Select an interface from the drop-down list.

Specifies the public device interface. You can specify only
one DDNS service on each interface.

 Service Name: Select the DDNS service provider from the

drop-down list for which the host names of the interface
have been registered. DYNDNS (Dynamic Network
Servicves, Inc.) or TZO (Tzolkin Corporation).

 Username/Password: Enter the username and password

for the DDNS service.

 Type of System: Select a type of system from the

drop-down list: Dynamic DNS, Static DNS, or Custom
DNS. Dynamic DNS associates your hostname with the
ISP-assigned dynamic IP address, updates the IP address
when notified of changes, and propagates the update
throughout the DNS server system. Static DNS associates
your hostname with your ISP-assigned static IP address.
Although automatic updates are allowed, changes to the IP
address are expected to be less frequent, and will take
longer to propagate though the DNS system. Custom DNS

jetSpeed 520+ User’s Manual

is a full DNS solution for newly purchased domains or
domains you already own. A web-based interface provides
complete control over resource records and your entire
domain, including support for dynamic IP addresses and
automated updates. You can create different domains in
these systems.

 Wildcard: Specifies whether the service provider can use a

wildcard DNS record to resolve variations on the host name
to the associated IP address. When enabled, a wildcard
record of DNS record type CNAME is used to resolve
queries for addresses of the form *.yourhost.ourdomain.ext
to the same IP address as found in the DNS record for
yourhost.ourdomain.ext.

 Mail Exchanger: Specifies a Mail Exchanger (MX) server

name to use for e-mails addressed to the hostname. The
specified MX must resolve to an IP address or it will be
ignored. Providing no MX setting (or an MX that does not
resolve properly to a DNS record of type A) causes the
hostname's MX record(s) to be removed.

 Mail Backup: Specifies whether or not e-mails are to be

backed up by the service provider.

 Offline Support: Specifies whether or not users will be

redirected to a designated service provider site when the
host computer is not available.

10.10 Autodetect

Click on the Autodetect link which enables the modem to

Autodetect eliminates the need to have users configure VC
values.

Autodetect can be used to establish PPPoE, PPPoA,
IPoA-1577 and EoA connections and can be configured in
either of two modes: bridging mode and routing mode. These
modes are specific to the Autodetect feature and are configured
in addition to the system operating mode defined on the
modem.

65 / 97

jetSpeed 520+ User’s Manual

When Autodetect is configured in bridging mode, it can detect
the presence of PPPoE and EoA interfaces on the access
server. In this mode, the modem must be configured as a
bridge and a PPPoE or DHCP client is expected to be running
on the LAN PC (behind the modem).
When configured in routing mode, Autodetect can
detect PPPoE, EoA, PPPoA, or IPoA-1577 interfaces on the
access server. Autodetect searches for these interfaces in that
order. Depending on the interface detected, Autodetect creates
a PPP, EoA, or IPoA interface on the modem. In this mode, the
modem is expected to be configured as a router.

10.11 SNMP

Click on the SNMP link to configure the SNMP trap settings.
The Simple Network Management Protocol (SNMP) enables a
host computer to access configuration, performance, and other
system data that resides in a database on the modem. The host
computer is called a management station and the modem is
called an SNMP agent. The data that can be accessed via
SNMP is stored in a Management Information Database (MIB)
on the modem.

When SNMP is enabled, the modem responds to SNMP
requests from the host. The host may ask to read data from the
MIB or, when its privileges allow, write data to it.

66 / 97

jetSpeed 520+ User’s Manual

Privilege levels are defined by the SNMP communities
configured on the modem. A community is a named group of IP
addresses. These addresses identify the hosts that are
permitted to act as SNMP management stations for accessing
the MIB. Each community is defined as having either read-only
or read/write privileges.

The data stored in the MIB includes the standard items defined
for the SNMP protocol and custom items defined by the ISP.
The MIB contents are preconfigured by the ISP and cannot be
managed via the Web-based interface.

On the SNMP Configuration page, type a community name in
the empty text box in the left column of the table.
From the Access column of the table, select the privileges
(read-only or read/write) to assign to all hosts that are part of
this community and then click Add Comm.
