ZyXELP-330W User’s Guide
Chapter 3 Wizard Setup 30
One of the benefits of PPPoE is the ability to let end users 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 specific users.
Operationally, PPPoE saves significant effort for both the subscriber and the ISP/carrier, as it
requires no specific configuration of the broadband modem at the subscriber’s site.
By implementing PPPoE directly on the P-330W (rather than individual computers), the
computers on the LAN do not need PPPoE software installed, since the P-330W does that part
of the task. Furthermore, with NAT, all of the LAN's computers will have Internet access.
Refer to the appendix for more information on PPPoE.

3.2.4 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables transfers 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.
