Prestige 660H Series Compact Guide

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