Chapter 1 Getting To Know Your Prestige

Universal Plug and Play (UPnP)
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 (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. The Prestige also includes PPPoE idle time-out (the PPPoE 
connection terminates after a period of no traffic that you configure) and PPPoE Dial-on-
Demand (the PPPoE connection is brought up only when an Internet access request is made).
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).
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.
DHCP
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) 
to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The 
Prestige has built-in DHCP server capability enabled by default. It can assign IP 
addresses, an IP default gateway and DNS servers to DHCP clients. The Prestige can now 
also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment 
from the actual real DHCP server to the clients.
IP Alias
IP Alias allows you to partition a physical network into logical networks over the same 
Ethernet interface. The Prestige supports three logical LAN interfaces via its single 
physical Ethernet interface with the Prestige itself as the gateway for each LAN network.
IP Policy Routing (IPPR)
Traditionally, routing is based on the destination address only and the router takes the 
shortest path to forward a packet.  IP Policy Routing (IPPR) provides a mechanism to 
override the default routing behavior and alter the packet forwarding based on the policy 
defined by the network administrator.
