Operationally, PPPoE saves significant effort for both you and the ISP or carrier,
as it requires no specific configuration of the broadband modem at the customer
site.
By implementing PPPoE directly on the Business Secure Router (rather than
individual computers), the computers on the LAN do not need PPPoE software
installed, since the Business Secure Router does that part of the task. Furthermore,
with NAT, all of the computers on the LAN have access.
The screen shown in Figure 24 is for PPPoE encapsulation.
