Getting to Know Your Prestige 

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. 

Traffic Redirect is used to sustain the Internet connection. The Prestige detects if the connectivity has been 
lost and will forward the outgoing traffic to another specified gateway. 

SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information 
between network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP 
agent functionality, which allows a manager station to manage and monitor the Prestige through the network. 
The Prestige supports SNMP version one (SNMPv1).  

NAT (Network Address Translation - NAT, RFC 1631) allows the translation of an Internet Protocol address 
used within one network to a different IP address known within another network. The Prestige can now map 
multiple global IP addresses to local IP addresses of clients or servers. 

DHCP (Dynamic Host Configuration Protocol) allows the individual clients (workstations) 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, which means it can assign IP addresses, an IP default gateway and DNS 
servers to Windows 9x, Windows NT, Windows 2000 and other systems that support the DHCP client. 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. 

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. 

Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way to 
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to 
support multicast groups. The latest version is version 2 (see RFC 2236). The Prestige supports versions 1 
and 2. 

PPPoE facilitates the interaction of a host with a broadband modem to achieve access to high-speed data 
networks via a familiar "dial-up networking" user interface.
