To set up a PPPoE or PPPoA connection:
1.
If not already selected, choose the
PPPoE/PPPoA
option from the
WAN Settings
pull-down menu.
PPPoE/PPPoA is selected by default if you are configuring the Router for the first time.
2.
Under the
ATM VC Settings
at the top of the window should not be changed unless you have been instructed to
change them. However, if you are instructed to change the
VPI
or
VCI
values, type in the values assigned for your
account. Leave the
PVC
and
Virtual Circuit
setting at the default (
Pcv0
and
Enabled
) values for now. This can be
used later if you are configuring multiple virtual circuits for your ADSL service. For more information on ATM
VC Settings, see the table on page 39 below.
3.
Under the
PPPoE/PPPoA
heading, type the
User Name
and
Password
used for your ADSL account. A typical
User Name will be in the form
. The Password may be assigned to you by your ISP or you
may have selected it when you set up the account with your ISP.
4.
Choose the correct
Authentication Type
from the drop-down menu. Most users will want to leave the setting on
Auto
.
PAP
and
CHAP
are the other two options.
5.
Choose the
Connection Type
from the pull-down menu located under the User Name and Password entry fields.
This defines both the connection protocol and encapsulation method used for your ADSL service. The available
options are
PPPoA VC-Mux, PPPoA LLC
and
PPPoE LLC.
If have not been provided specific information for the
Connection Type setting, leave the default setting.
6.
Leave the
MTU
value at the default setting (default =
1400
) unless you have specific reasons to change this (see
table below).
7.
Leave the
MRU
value at the default setting (default =
1492
) unless you have specific reasons to change this (see
table below).
8.
Leave the
Default Route
enabled if you want to use the Router as the default route to the Internet for your LAN.
Whenever a computer on the LAN attempts to access the Internet, the Router becomes the Internet gateway to the
computer. If you have an alternative route for Internet traffic you may disable this without effecting the Router’s
connection.
9.
Enable
PPPoE PassThrough
if you want the Router to allow a “dial-up” or separate bridged PPP connection to an
individual PC.
10.
NAT
should remain
Enabled
. If you disable NAT, you will not be able to use more than one computer for Internet
connections. NAT is enabled and disabled system-wide, therefore if you are using multiple virtual connections,
NAT will disabled on all connections.
11.
The
Firewall
should remain enabled for most users. If you choose to disable this you will not be able to use the
features configured in the
Firewall Configuration
and
Filters
windows located in the
Advanced
directory. See
the next chapter for more details on these windows.
12.
Typically the globally IP settings (i.e. IP address for the WAN interface) for a PPPoA or PPPoA connection will
use Dynamic IP assignment from the ISP. Some accounts may be assigned a specific global IP address. If you
have been give an IP address for you PPPoE/PPPoA connection, select the
Static IP
option from the
IP Control
pull-down menu. This menu can be used to configure the WAN port as an Unnumbered IP interface. (See table
below for Unnumbered IP).
13.
Point-to-Point Tunneling Protocol is a pass-through mechanism that allows packets to pass through the Router so
that it effectively functions as a bridge. Check
Enable
PPTP
and enter the required information in the
ServerIP/Name
,
Route Target
,
Route Mask
,
PPTP Account
,
PPTP Password
, and
MPPE Encryption
fields.
14.
Most users will not need to change
ATM
settings. If this is the first time you are setting up the ADSL connection
it is recommended that you leave the
Service Category
settings at the default values until you have established the
connection. See the table on page 37 for a description of the parameters available for ATM traffic shaping.
