5.2.3 PPPoE
PPPoE provides session authentication using either Password Authentication Protocol (PAP) or
Challenge Handshake Authentication Protocol (CHAP). Session accounting is possible and
conservation of bandwidth can be achieved by closing down unused sessions. By utilizing PPP,
link and network parameters are easily negotiated between the IAD/Router and the ISP.
When using PPPoE, the system is assigned an IP address from the Internet Service Provider as
part of establishing the network connection. The system can be configured as a DHCP server for
the LAN, and NAT can be used to translate private addresses to public addresses. In this way,
computers in the LAN do not have to have their own public IP addresses.
To set up PPPoE, click on on PPPoE, configure the common fields on the top of the page, then
following fields. Click on on the
Add button to add the entry.
User name/Password: Used for remote customers to login during dialup.
Dialing Mode: Direct and Auto. If the mode is set to AUTO , the PPPoE negotiation
automatically starts when the system identifies any traffic required to be transferred on the
link. When
DIRECT is selected, the PPPoE negotiation is started manually using the
pppoestart command. The default is AUTO with 30 minutes idle timeout.
Idle Timeout: defines the period of idle time (minutes) after which the PPPoE link will be
terminated. This field is necessary to configure under AUTO mode. After a period of
inactivity (equal to the timeout value), the device automatically disconnects the user from
the network.
Authentication: defines the authentication code: PAP, CHAP, MSCHAPV1 and
MSCHAPV2.
