One of the benefits of PPPoE is the ability to let you access one of multiple network
services, a function known as dynamic service selection. This enables the service
provider to easily create and offer new IP services for individuals.
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 NBG4604 (rather than individual
computers), the computers on the LAN do not need PPPoE software installed,
since the NBG4604 does that part of the task. Furthermore, with NAT, all of the
LANs’ computers will have access.

PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure
transfer of data from a remote client to a private server, creating a Virtual Private
Network (VPN) using TCP/IP-based networks.
PPTP supports on-demand, multi-protocol and virtual private networking over
public networks, such as the Internet.
