Chapter 1 Getting to Know Your Prestige 47
1.2.2.17 Dynamic DNS Support
With Dynamic DNS (Domain Name System) 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.
1.2.2.18 IP Multicast
Deliver IP packets to a specific group of hosts using IP multicast. 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 both versions 1 and 2.
1.2.2.19 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 LAN interface with the Prestige itself as the gateway for each LAN network.
1.2.2.20 SNMP
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) and version two (SNMPv2).
1.2.2.21 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).
1.2.2.22 Traffic Redirect
Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the Prestige
cannot connect to the Internet, thus acting as an auxiliary backup when your regular WAN
connection fails.
1.2.2.23 Port Forwarding
Use this feature to forward incoming service requests to a server on your local network. You
may enter a single port number or a range of port numbers to be forwarded, and the local IP
address of the desired server.
