DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows individual clients (computers) to obtain 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.

o PPP over PAP (RFC 1334).
