A Powerful, True Firewall with Content Filtering

Unlike simple NAT routers, the VPN firewall is a true firewall, using stateful packet inspection

(SPI) to defend against hacker attacks. Its firewall features have the following capabilities:

• DoS protection.

Automatically detects and thwarts denial of service (DoS) attacks such

as Ping of Death and SYN flood.

• Secure firewall. Blocks un

wanted traffic from the Internet to your LAN.

• Content fil

tering. Prevents objectionable content from reaching your computers. You

can control access to Internet content by screening for web services, web addresses, and

keywords within web addresses.

• Schedul

e policies. Permits scheduling of firewall policies by day and time.

• Logs security incident

s. Logs security events such as logins and secure logins. You can

configure the firewall to email the log to you at specified intervals. You can also configure

the VPN firewall to send immediate alert messages to your email address or email pager

when a significant event occurs.

Security Features

The VPN firewall is equipped with several features designed to maintain security:

• Computers h

idden 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

computers on the LAN.

• Port forwarding

with NAT. Although NAT prevents Internet locations from directly

accessing the computers on the LAN, the VPN firewall allows you to direct incoming

traffic to specific computers based on the service port number of the incoming request.

• DMZ po

rt. Incoming traffic from the Internet is usually discarded by the VPN firewall

unless the traffic is a response to one of your local computers or a service for which you

have configured an inbound rule. Instead of discarding this traffic, you can use the

dedicated demilitarized zone (DMZ) port to forward the traffic to one computer on your

network.

Autosensing Ethernet Connections with Auto Uplink

With its internal four-port 10/100/1000 Mbps switch and four 10/100/1000 WAN ports, the

VPN firewall can connect to a 10-Mbps standard Ethernet network, a 100-Mbps Fast Ethernet
