Getting To Know Your Prestige 1-3
Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically join a
network, obtain an IP address and convey its capabilities to other devices on the network.

PPPoE Support (RFC2516)
PPPoE (Point-to-Point Protocol over Ethernet) emulates a dial-up connection. It allows your ISP to use their
existing network configuration with newer broadband technologies such as ADSL. The PPPoE driver on the
Prestige is transparent to the computers on the LAN, which see only Ethernet and are not aware of PPPoE
thus saving you from having to manage PPPoE clients on individual computers.
•
Network Address Translation (NAT)
Network Address Translation (NAT) allows the translation of an Internet protocol address used within one
network (for example a private IP address used in a local network) to a different IP address known
within another network (for example a public IP address used on the Internet).
10/100M Auto-negotiating Ethernet/Fast Ethernet Interface(s)
This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust
appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either
half-duplex or full-duplex mode depending on your Ethernet network.
Auto-crossover 10/100 Mbps Ethernet Interface(s)
These interfaces automatically adjust to either a crossover or straight-through Ethernet cable. This feature is
only applicable to the P652H/HW. The P652R has an uplink button that allows you to switch between
crossover and straight-through Ethernet cables.
LAN/DMZ Interface
The P652H/HW provides a LAN port that can function as a virtual DeMilitarized Zone (DMZ) port
1
. Public
servers (Web, FTP, etc.) attached to the DMZ port are visible to the outside world (while still being protected
from DoS (Denial of Service) attacks such as SYN flooding and Ping of Death) and can also be accessed
from the secure LAN.
Dynamic DNS Support
With Dynamic DNS support, you can have a static hostname alias for a dynamic IP address, allowing the
host to be more easily accessible from various locations on the Internet. You must register for this service
with a Dynamic DNS service provider.
