About Firewall Protection and Content Filtering

The ProSafe VPN Firewall provides you with Web content filtering options, plus browsing
activity reporting and instant alerts via e-mail. 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. You can further segment keyword blocking to certain known
groups (see "Managing Groups and Hosts (LAN Groups)" on page 3-5

to set up LAN Groups).
