Getting to Know Your Prestige

This chapter introduces the main features and applications of the Prestige.

1.1 Prestige Overview

The Prestige is the ideal secure wireless firewall router for all data passing between the
Internet and LAN’s.

The Prestige provides NAT, port forwarding, firewall, DHCP server and many other powerful
features. The Prestige has an embedded mini-PCI module for 802.11g Wireless LAN
connectivity.

P-320W User’s Guide

CHAPTER 1

The embedded web configurator is easy to operate.

Note: Only use firmware for your Prestige’s specific model.

1.2 Prestige Features

The following sections describe Prestige features.

1.2.1 Physical Features

10/100 Mbps 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-negotiation allows data transfer of 100 Mbps in full-duplex mode

Auto-crossover 10/100 Mbps Ethernet Interface(s)

These interfaces automatically adjust to either a crossover or straight-through Ethernet cable.

4-Port Switch

A combination of switch and router makes your Prestige a cost-effective and viable network
solution. You can add up to four computers to the Prestige without the cost of a hub. Add more
than four computers to your LAN by using a hub.

Chapter 1 Getting to Know Your Prestige 27

P-320W User’s Guide

Reset Button

The Prestige reset button is built into the rear panel. Use this button to restore the factory
default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP
server enabled with a pool of 32 IP addresses starting at 192.168.1.33.

1.2.2 Non-Physical Features

Firewall

The Prestige is a stateful inspection firewall with DoS (Denial of Service) protection. By
default, when the firewall is activated, all incoming traffic from the WAN to the LAN is
blocked unless it is initiated from the LAN. The Prestige firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.

Packet Filtering

The packet filtering mechanism blocks unwanted traffic from entering/leaving your network.

Time and Date

The Prestige allows you to get the current time and date from an external server when you turn
on your Prestige. You can also set the time manually.

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

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

PPTP Encapsulation

Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of
data from a remote client to a private server, creating a Virtual Private Network (VPN) using a
TCP/IP-based network.

PPTP supports on-demand, multi-protocol and virtual private networking over public
networks, such as the Internet. The Prestige supports one PPTP server connection at any given
time.

P-320W User’s Guide

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.

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.

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).

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).

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.

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.

DHCP (Dynamic Host Configuration Protocol)

DHCP (Dynamic Host Configuration Protocol) allows the individual client 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, which means it can assign IP addresses,
an IP default gateway and DNS servers to all systems that support the DHCP client.

Chapter 1 Getting to Know Your Prestige 29

P-320W User’s Guide

Full Network Management

The embedded web configurator is an all-platform web-based utility that allows you to easily
access the Prestige’s management settings and configure the firewall. Most functions of the
Prestige are also software configurable via the SMT (System Management Terminal)
interface. The SMT is a menu-driven interface that you can access over a telnet connection.

RoadRunner Support

In addition to standard cable modem services, the Prestige supports Time Warner’s
RoadRunner Service.

Logging and Tracing

• Built-in message logging and packet tracing.

• Firewall logs.

• Content filtering logs.

Upgrade Prestige Firmware via LAN

The firmware of the Prestige can be upgraded via the LAN (refer to Maintenance- F/W Upload
Screen).

Embedded FTP and TFTP Servers

The Prestige’s embedded FTP and TFTP Servers enable fast firmware upgrades as well as
configuration file backups and restoration.

1.2.3 Wireless Features

Wireless LAN

The Prestige supports the IEEE 802.11g standard, which is fully compatible with the IEEE

802.11b standard, meaning that you can have both IEEE 802.11b and IEEE 802.11g wireless
clients in the same wireless network.

Note: The Prestige may be prone to RF (Radio Frequency) interference from other

2.4 GHz devices such as microwave ovens, wireless phones, Bluetooth
enabled devices, and other wireless LANs.

Wi-Fi Protected Access

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification standard.
Key differences between WPA and WEP are user authentication and improved data
encryption.
