A Powerful, True Firewall with Content Filtering

Unlike simple Internet sharing NAT firewalls, the FVS114 is a true firewall, using stateful packet

inspection to defend against hacker attacks. Its firewall features include:

• DoS protection.

Automatically detects and thwarts DoS attacks such as Ping of Death, SYN Flood, LAND

Attack, and IP Spoofing.

• Blocks unwanted traffic from the Internet to your LAN.

• Blocks access from your LAN to Internet locations or services that you specify as off-limits.

• Logs security incidents.

The FVS114 logs security events such as blocked incoming traffic, port scans, attacks, and

administrator logins. You can configure the firewall to email the log to you at specified

intervals. You can also configure the firewall to send immediate alert messages to your e-mail

address or email pager whenever a significant event occurs.

• With its content filtering feature, the FVS114 prevents objectionable content from reaching

your PCs. The firewall allows you to control access to Internet content by screening for

keywords within Web addresses. You can configure the firewall to log and report attempts to

access objectionable Internet sites.

Security

The FVS114 VPN Firewall is equipped with several features designed to maintain security, as

described in this section.

• PCs Hidden by NAT

NAT opens a temporary path to the Internet for requests originating from the local network.

Requests originating from outside the LAN are discarded, preventing users outside the LAN

from finding and directly accessing the PCs on the LAN.

• Port Forwarding with NAT

Although NAT prevents Internet locations from directly accessing the PCs on the LAN, the

firewall allows you to direct incoming traffic to specific PCs based on the service port number

of the incoming request, or to one designated “DNS” host computer. You can specify

forwarding of single ports or ranges of ports.
