Prestige 652 Series User's Guide

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.
You can configure most features of the Prestige via SMT but we recommend you
configure the firewall and content filters using the web configurator.

Content Filtering
Content filtering allows you to block access to forbidden Internet web sites, schedule when the Prestige
should perform the filtering and give trusted LAN IP addresses unfiltered Internet access.
IEEE 802.11b 11 Mbps Wireless LAN
The 11 Mbps wireless LAN provides mobility and a fast network environment for small and home offices.
Computers with wireless LAN Ethernet adapters can connect to the local area network without any wiring
efforts and enjoy reliable high-speed connectivity.
Wireless LAN MAC Address Filtering
MAC Address Filtering together with ESSID (Extended Service Set IDentifier) and WEP (Wired Equivalent
Privacy) provide enhanced security for your wireless LAN.
Traffic Redirect
Traffic redirect forwards WAN traffic to a backup gateway when the Prestige cannot connect to the Internet,
thus acting as an auxiliary if your regular WAN connection fails.
Auxiliary Port
The auxiliary port (or dial backup port) can be used in reserve as a traditional dial-up connection when/if
ever the broadband connection to the WAN port fails. The P652H/HW uses the same port (labeled
CON/AUX) for console management and for an auxiliary WAN backup (push the CON/AUX switch to
CON or AUX).
Bandwidth Management
Bandwidth management allows you to allocate network resources according to defined policies. This policy-
based bandwidth allocation helps your network to better handle real-time applications such as Voice-over-IP
(VoIP).
