DNS
Domain Name Servers are used to map a domain name (e.g. www.somesite.com) to the equivalent numerical
IP address (e.g. 64.147.25.20). Your ISP should provide the IP address of one or more Domain Name Servers. Enter
those addresses on this page.
WAN
Specify the WAN connection parameters provided by your Internet Service Provider (ISP). The router can be
connected to your ISP in one of the following ways:
ATM PVC
Clone MAC
Note:
If you check ‘Enabled’
and specify an IP address
of 0.0.0.0, any host can
manage the router.
For remote
management via a 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,
This applies unless you
change the port setting,
in which case you need
to substitute the 8080
for whatever port you
have assigned.

ATM PVC
The router uses ATM as its WAN interface. Click on each ATM VC for WAN configuration.
Parameter Description
Description:
Click on the VC to set the values for the connection.
VPI/VCI:
Virtual Path Identifier (VPI) and Virtual Circuit Identifier (VCI).
Encapsulation:
Specifies how to handle multiple protocols at the ATM transport layer.
VC-MUX: Point-to-Point Protocol over ATM Virtual Circuit Multiplexer (null encapsulation) allows only one
protocol running per virtual circuit with less overhead.
LLC: Point-to-Point Protocol over ATM Logical Link Control (LLC) allows multiple protocols running over one
virtual circuit (using slightly more overhead).
Protocol:
Protocol used for the connection.

ATM Interface
Clicking on the ATM VC brings up the following screen. The router uses ATM as its WAN interface. Protocols
including 1483 Routing, 1483 Bridging, MAC Encapsulated Routing (MER), PPPoA and PPPoE with LLC-SNAP and VC-
MUX encapsulations are supported for each ATM PVC.
When you have finished entering your connection parameters, click ‘SAVE SETTINGS’. You can verify that you
have established an ADSL connection by clicking ‘Status’ at the bottom of the left-hand menu.
See below for a description of the parameters.
Parameter Description
Protocol
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. Please note
that setting the router to bridged mode disables
all advanced features such as VoIP, Firewall, and
QoS, etc
PPPoA:
Point-to-Point Protocol over ATM is a
method of encapsulating data for transmission to
a far point
1
483 Routing:
1483 Routing allows a simple, low-cost
connection to the Internet via a standard Ethernet
port. The router 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 router (i.e.,
the router at the head end)

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 to do IP routing with NAT enabled
VPI/VCI
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.

Encapsulation
Shows the packet encapsulation type.
Packet encapsulation specifies how to handle
multiple protocols at the ATM transport layer.
VC-MUX:
Point-to-Point Protocol over ATM Virtual
Circuit Multiplexer (null encapsulation) allows only
one protocol running per virtual circuit with less
overhead
LLC:
Point-to-Point Protocol over ATM Logical Link
Control allows multiple protocols running over one
virtual circuit (using slightly more overhead)
QoS Class
ATM QoS classes including CBR, UBR and VBR.
PCR/SCR/MBS
QoS Parameters - PCR (Peak Cell Rate), SCR
(Sustainable Cell Rate) and MBS (Maximum Burst Size)
are configurable.
Connect Type
Sets connection mode to always connected,
automatic or manual connection.
Idle Time: Enter the maximum idle time for the
Internet connection.(in minutes) After this time has
been exceeded the connection will be terminated.
Username:
Enter user name
Password:
Enter password
Confirm password:
Confirm Password
MTU
Leave the Maximum Transmission Unit (MTU) at the
default value (1500) unless you have a particular
reason to change it.
Clone MAC Address
Clicking on the Clone MAC Address brings up the following screen.
Some ISPs may require that you register your MAC address with them. If this is the case, the MAC address of the
router must be changed manually to the MAC address that you have registered with your ISP.

LAN
Use the LAN menu to configure the LAN IP address and to enable the DHCP server for dynamic client address
allocation.
Parameter Description
LAN IP
IP Address:
The IP address of the router
IP Subnet Mask:
The subnet mask of the router
Host Name:
If your ISP requires a hostname specified
enter it here, otherwise leave blank
DHCP Server:
To dynamically assign an IP address to
client PCs, enable the DHCP (Dynamic Host
Configuration Protocol) Server
VLAN Binding
In this section you can assign VLAN’s that you have
created in the VLAN page to certain ports such as
LAN port 1, 2, 3 or 4 and the WLAN connection. For
instance if you have created a VLAN Binding called
‘Test’, and you want anything connected to the
wireless to be on that VLAN, then you would change
the WLAN setting on this page from ‘Default’ to the
one you created called ‘Test’.
DHCP SERVER
DHCP Option 60 Vendor ID:
If you wish you can
specify the Name of your DHCP Server (Optional).
Lease Time:
Specify the length of time that the
DHCP will assign an IP address to a computer for.
IP Address Pool
Start IP:
Specify the start IP address of the DHCP pool
Do not include the gateway address of the router in
the client address pool (see ‘TCP/IP
Configuration’). If you attempt to include the router
gateway address (10.1.1.1 by default) in the DHCP pool,
an error dialog box will appear. If you change the pool
range, make sure the first three octets match the
gateway’s IP address, i.e.10.1.1.xxx
End IP:
Specify the end IP address of the DHCP pool.
Domain Name:
If your network uses a domain name,
enter it here. Otherwise, leave this field blank
