Firewall Protection and Content Filtering Overview
The 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.
