4.4.1.2 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 ADSL. 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 the ADSL router to terminate the PPPoA connection. The advantage is that the PPPoA termination is done within the ADSL router and not on your computer; this frees up your computer’s resources and allows multiple users to utilise 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 ADSL Provider or ISP will supply these; in this case, the ADSL Provider is using 0,100. Also select the Quality of Service (QoS); leave the default value if you are unsure or the ISP did not provide this information.

The following is a description of the different options:

a.Username: The username for the PPPoA access; this is provided by your ADSL Provider or ISP.

b.Password: The password for the PPPoA access; this is provided by your ADSL Provider or 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 enabled, 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.Set Route: Specify this connection as the default route.

g.MRU: Maximum Receive Unit the ADSL 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 ADSL Providers/ISPs require a larger value. The minimum MRU value is 128.
