4.2.2 PPTP Encapsulation
Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables 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.
For more information on PPTP, please refer to
the appendices
The Prestige supports one PPTP server connection at any given time.

4.2.3 PPPoE Encapsulation
Point-to-Point Protocol over Ethernet (PPPoE) functions as a dial-up connection. PPPoE is an IETF
(Internet Engineering Task Force) draft standard specifying how a host personal computer interacts with a
broadband modem (for example xDSL, cable, wireless, etc.) to achieve access to high-speed data networks.
It preserves the existing Microsoft Dial-Up Networking experience and requires no new learning or
procedures.
For the service provider, PPPoE offers an access and authentication method that works with existing access
control systems (for instance, Radius). For the user, PPPoE provides a login and authentication method that

Wizard Setup
the existing Microsoft Dial-Up Networking software can activate, and therefore requires no new learning or
procedures for Windows users.
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 end user and ISP/carrier, as it requires no specific
configuration of the broadband modem at the customer site.
By implementing PPPoE directly on the Prestige (rather than individual computers), the computers on the
LAN do not need PPPoE software installed, since the Prestige does that part of the task. Furthermore, with
NAT, all of the LAN's computers will have access.
For more information on PPPoE, please refer

4.3.1 WAN IP Address Assignment
Every computer on the Internet must have a unique IP address. If your networks are isolated from the
Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts
without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following
three blocks of IP addresses specifically for private networks.
