4.4.3 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 router and the Internet 
Service Provider (ISP). 
When using PPPoE, the system is assigned an IP address from the ISP 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 PPPoE, configure the common fields on the top of the page and the 
following fields. At the bottom of the screen, click on the Add button to add the entry. If the 
PPPoE mode is set to auto, clicking on the MANUAL MODE Enable button will effectively 
disable auto-mode, and require the user to reconnect a terminated PPPoE session by clicking 
the MANUAL MODE Trigger button. Subsequently, to return to auto-mode, click on the 
MANUAL MODE Disable button, which will appear in place of the MANUAL MODE Enable 
button. 
 
User name/Password: Used for remote customers to login during dialup.  
 
 
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 an idle timeout of 30 minutes.  
 
 
Idle Timeout: Defines the period of idle time (in 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 and CHAP.  
 
Enable DHCP Server: Enables (if checked) or disables the DHCP server.  The DHCP 
server dynamically allocates network addresses and delivers configuration parameters to 
hosts.
