Connection Type
Connection Type Window (PPPoE)
The default connection method used by the Router for the WAN connection is
PPP over Ethernet. If you wish to use this method you do not need to change this
setting. However if you are using a static IP address (also called “Bridged
Ethernet” encapsulation as defined by RFC 1483), or PPP over ATM (RFC 2364)
you can select them here.
To change the connection method, select either Router with RFC 1483
 or
Router with PPPoA...

Static IP Address Configuration (for RFC 1483)
Static IP Address Configuration Window
In the Static IP Address configuration window enter the static IP Address
 and
subnet mask assigned by your network service provider for your WAN interface.
The Static IP Address is a globally unique IP address used to identify the Router
on the Internet. If you are given a Default Gateway
 IP address enter that here
as well. The default gateway is another Router used to provide...

PPPoA Configuration
PVC
Use this field to assign the VPI
 and VCI
 values for the Router. These numbers
are given to you by your DSL service provider and must be entered in order to
establish the ADSL connection.
PPPoA Login
Use this field to assign a Login User Name
 and Password
 used for
authentication by your network service provider. Type in the user name and

If your network account is not billed according to the amount of time connected,
the Idle Time 
field should be left at the default value 0. This means that the
Router is always connected and able to connect on demand.
If your network account is billed according to the amount of time the Router is
actually connected to the Internet, enter an appropriate Idle Time 
value (in
seconds). This will disconnect the Router after the WAN connection has been idle
for the amount...

Line Condition
Line Condition
In the Line Condition window you can monitor the characteristics of the ADSL
connection and confirm that it has been established. From here you can observe
various performance statistics of each end of the connection, including:
Data Path

 or Interleaved
.
Operation Mode
: Describes the of modulation technique used to make the
ADSL connection. This will be either Discrete Multi-tone modulation...

Router Functions
The DHCP and NAT functions of the Router allows the network manager to more
easily manage IP addresses and subnets, and enhance network security by
presenting only one global IP address to the Internet. This section discusses how
to use these conventional routing functions.
DHCP
The Dynamic Host Configuration Protocol (DHCP) allows the Router to assign IP
addresses to all properly configured hosts on the network. Dynamic IP
assignment alleviates the...

Netmask
This mask informs the client, how the destination IP address is to be divided into
network, subnet, and host parts. The netmask has ones in the bit positions in the
32-bit address which are to be used for the network and subnet parts, and zeros
for the host part.
Default Gateway
This specifies the Gateway IP Address that will be assigned to and used by the
DHCP clients.
Leased Time
This specifies the amount of time (in seconds) a client can lease an IP...

Port Redirection to allow appropriate use of your servers by outside users. See
the section on Port Redirection for more information.
For the purposes of network administration, NAT is almost indispensable. Hosts
and servers on the internal network can be moved easily. Using NAT together
with DHCP can greatly reduce the workload of a network manager while
allowing tremendous flexibility.
NAT Configuration Window
The NAT function is enabled by default on the Router. If...

Security Features
Network security is an unfortunate necessity for any network connected to the
Internet. Protection of sensitive information and proprietary assets on your
private network should be designed into the network infrastructure from the
beginning. If you are not already, it is recommended that you become familiar
with network security issues and the strategies available to help reduce risks
from outside as well as from within your LAN. The Router provides...
