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.

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.
