Using the PPP Option to Configure Point-To-Point Protocol Connections on page 134
Use the PPPoE option to configure how the device handles Point-to-Point Protocol over
Ethernet (PPPoE) connections. PPPoE enables multiple users at a site to share the same
digital subscriber line, cable modem, or wireless connection to the Internet. Some security
devices support PPPoE, which enables them to operate compatibly on DSL, Ethernet
Direct, and cable networks run by ISPs that use PPPoE for their clients' Internet access.
NOTE: Some ISPs use DHCP for their clients' Internet access. To configure
DHCP on an interface, see "Example: Assigning TCP/IP Settings for Hosts
Using DHCP (NSM Procedure)" on page 58. For more detailed explanation
about PPPoE or DHCP on security devices, see the "Fundamentals" volume
in the Concepts & Examples ScreenOS Reference Guide.
On devices that support PPPoE, you can configure a PPPoE client instance on any or all
interfaces. You configure a specific instance of PPPoE with a username and password
and other parameters, and bind the instance to an interface. When two Ethernet interfaces
(a primary and a backup) are bound to the Untrust zone, you can configure one or both
interfaces for PPPoE. Specifically:
For all security devices running ScreenOS 5.0 and later, you can enable PPPoE on
multiple interfaces in any zone at the same time.
For all security devices running ScreenOS 5.1 and later, you can bind a PPPoE instance
to a:
VSI interface—Use this option when running two devices using NSRP in active-passive
mode. When failover occurs, the new primary device can use the same IP as the
previous primary device to continue communicating with the ISP. Because the PPPoE
