Firewall to protect your network. These features can be found by clicking on the Security heading
in the main menu of the browser interface.

Firewall Protection and Content Filtering Overview

The FVS318v3 ProSafe VPN Firewall provides you with Web content filtering options, plus
browsing activity reporting and instant alerts via e-mail. Parents and network administrators can
establish restricted access policies based on time-of-day, Web addresses and Web address
keywords. You can also block Internet access by applications and services, such as chat or games.
A firewall is a special category of router that protects one network (the trusted network, such as
your LAN) from another (the untrusted network, such as the Internet), while allowing
communication between the two. A firewall incorporates the functions of a NAT (Network
Address Translation) router, while adding features for dealing with a hacker intrusion or attack,
and for controlling the types of traffic that can flow between the two networks. Unlike simple
Internet sharing NAT routers, a firewall uses a process called stateful packet inspection to protect
your network from attacks and intrusions. NAT performs a very limited stateful inspection in that
it considers whether the incoming packet is in response to an outgoing request, but true stateful
packet inspection goes far beyond NAT.
To configure these features of your firewall, click on the subheadings under the Security heading
in the main menu of the browser interface. The subheadings are described below:
