RTS/CTS handshake. Data with its frame size larger than this value
will perform the RTS/CTS handshake. Setting this attribute to be
larger than the maximum MSDU (MAC Service Data Unit) size turns
off the RTS/CTS handshake.

Fragmentation Threshold is the maximum data fragment size that
can be sent.

WEP (Wired Equivalent Privacy) encrypts data frames before
transmitting them over the wireless network.

Select Disable allows all wireless computers to communicate with
the access points without any data encryption.

Select 64-bit WEP, 128-bit WEP or 256-bit WEP and then configure

6.3 802.1x and WPA Overview

Wi-Fi Protected Access (WPA) is a subset of the IEEE 802.11i security specification
draft. Key differences between WPA and WEP are user authentication and improved
data encryption. WPA applies IEEE 802.1x and Extensible Authentication Protocol
(EAP) to authenticate wireless clients using an external RADIUS database. You can’t
use the Prestige’s local user database for WPA authentication purposes since the local
user database uses MD5 EAP which cannot be used to generate keys.

WPA improves data encryption by using Temporal Key Integrity Protocol (TKIP),
Message Integrity Check (MIC) and IEEE 802.1x. Temporal Key Integrity Protocol
(TKIP) uses 128-bit keys that are dynamically generated and distributed by the
authentication server. It includes a per-packet key mixing function, a Message Integrity
Check (MIC) named Michael, an extended initialization vector (IV) with sequencing
rules, and a re-keying mechanism.

To change your Prestige’s authentication settings, click the Wireless LAN link under
Advanced Setup and then the 802.1x/WPA tab.

port control and key management protocol

The screen varies by the wireless

you select.

6.4 Network Address Translation Overview

NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP
address of a host in a packet. For example, the source address of an outgoing packet,
used within one network is changed to a different IP address known within another
network.

If you have a single public IP address then select SUA Only in the NAT-Mode screen
(see Figure 17). If you have multiple public IP addresses then you may use full feature
mapping types (see the User’s Guide for more details).

NAT supports five types of IP/port mapping. They are:

1. One-to-One: One-to-one mode maps one local IP address to one global IP
address. Note that port numbers do not change for One-to-one NAT mapping
type.

29

Prestige 660W/HW Series Compact Guide

2. Many-to-One: Many-to-One mode maps multiple local IP addresses to one
global IP address.

3. Many-to-Many Overload: Many-to-Many Overload mode maps multiple
local IP addresses to shared global IP addresses.

4. Many-to-Many No Overload: Many-to-Many No Overload mode maps each
local IP address to unique global IP addresses.

5. Server: This type allows you to specify inside servers of different services
behind the NAT to be accessible to the outside world.

6.5 Configuring SUA Server

An SUA server set is a list of inside (behind NAT on the LAN) servers, for example,
web or FTP, that you can make visible to the outside world even though SUA makes
your whole inside network appear as a single computer to the outside world.

Step 7. From the main screen click Advanced Setup and then NAT to open

the NAT-Mode screen. Select SUA Only.

Step 8. Click Edit Details.

6.6 Firewall Overview

The Prestige firewall is a stateful inspection firewall and is designed to protect against
Denial of Service attacks when activated. The Prestige’s purpose is to allow a private
Local Area Network (LAN) to be securely connected to the Internet. The Prestige can be
used to prevent theft, destruction and modification of data, as well as log events, which
may be important to the security of your network. The Prestige also has packet-filtering
capabilities.

When activated, the firewall allows all traffic to the Internet that originates from the
LAN, and blocks all traffic to the LAN that originates from the Internet. In other words
the Prestige will:

Allow all sessions originating from the LAN to the WAN
Deny all sessions originating from the WAN to the LAN

LAN-to-WAN rules are local network to Internet firewall rules. The default is to
forward all traffic from your local network to the Internet.

Make sure that you have the correct power adaptor connected to
the Prestige and plugged in to an appropriate power source. Check
all cable connections.

If the LEDs still do not turn on, you may have a hardware problem.
In this case, you should contact your local vendor.

Check the cable connection between the Prestige and your
computer or hub. Refer to the Rear Panel Connections section for
details.

Ping the Prestige from a LAN computer. Make sure your computer
Ethernet adapter is installed and functioning properly.

If the LAN LEDs are all off, check the cable connections between
the Prestige and your LAN computers.

Verify that the IP address, subnet mask of the Prestige and the LAN
computers are in the same IP address range.

Make sure the WLAN LED is on.

Make sure the wireless card on the wireless client is working
properly.

Check that both the Prestige and wireless client(s) are using the
same ESSID, channel and WEP keys (if WEP encryption is
activated).

The WAN IP is provided after the ISP verifies the MAC address,
host name or user ID. Find out the verification method used by your
ISP and configure the corresponding fields.

If the ISP checks the user ID, check your service type, user name,
and password in the WAN Setup screen.

Verify the Internet connection settings in the WAN Setup screen.

Make sure you entered the correct user name and password.

For wireless clients, check that both the Prestige and wireless
client(s) are using the same ESSID, channel and WEP keys (if WEP
encryption is activated).
