PPPoA CONNECTION SETUP
PPPoA is also known as RFC 2364. It is a method of encapsulating PPP packets over ATM cells
which are carried over the DSL line. PPP or Point-to-Point protocol is a method of establishing a
network connection / session between network hosts. It usually provides a mechanism of
authenticating users. LLC and VC are two different methods of encapsulating the PPP packet.
Contact your ISP to make sure which encapsulation is being supported.
By selecting PPPoA, you are forcing your gateway to terminate the PPPoA connection. The
advantage is that the PPPoA termination is done within the gateway and not on your PC; this frees up
your PC resources and allows multiple users to utilize the PPPoA connection.
To configure the gateway for PPPoA, click on Setup and then click on
New Connection
. The default
PPPoE connection setup is displayed. At the Type field select
PPPoA
and the PPPoA connection
setup page is displayed; figure 5 illustrates a typical PPPoA configuration. Give your PPPoA
connection a unique name; the name must not have spaces and cannot begin with numbers. In this
case the unique name is called
PPPOA1
. Select the encapsulation type (LLC or VC); if you are not
sure just use the default mode. Select the VPI and VCI settings; your DSL service provider or your
ISP will supply these; in this case the DSL service provider is using
0,40
. Also select the quality of
service (QOS); leave the default value if you are unsure or the ISP did not provide this information.
Following is a description of the different options:
a.
Username: The username for the PPPoA access; this is provided by your DSL service
provider or your ISP.
b.
Password: The password for the PPPoA access; this is provided by your DSL service
provider or your ISP.
c.
On-Demand: Enables on-demand mode. The connection will disconnect if no activity is
detected after the specified idle timeout value.
d.
Idle Timeout: Specifies that PPPoA connection should disconnect if the link has no
activity detected for n seconds. This field is used in conjunction with the On-Demand
feature. To ensure that the link is always active, enter a 0 in this field.
e.
Keep Alive: When on-demand option is not enable, this value specifies the time to wait
without being connected to your provider before terminating the connection. To ensure
that the link is always active, enter a 0 in this field.
f.
Maxfail: As long as a DSL connection is established, the gateway will attempt to
establish a PPPoA connection. If after n consecutive failed connection attempts the
gateway will wait for some random time before trying to establish the connection again.
A value of 0 means no limit.
g.
Set Route: Specify this connection as the default-route.
h.
MRU: Maximum Receive Unit the DSL connection can receive. It is a negotiated value
that asks the provider to send packets of no more than n bytes. The maximum specified
value is 1500 although some DSL/ISP providers require a larger value. The minimum
MRU value is 128.
i.
Debug: Enables PPPoA connection debugging facilities. Debugging is talked about
later.
