Firewalls
10.1 Overview
This chapter shows you how to enable and configure the Device firewall. Use these screens to
enable and configure the firewall that protects your Device and network from attacks by hackers on
the Internet and control access to it. By default the firewall:
• allows traffic that originates from your LAN computers to go to all other networks.
• blocks traffic that originates on other networks from going to the LAN.
The following figure illustrates the default firewall action. User
A
can initiate an IM (Instant
Messaging) session from the LAN to the WAN (1). Return traffic for this session is also allowed (2).
However other traffic initiated from the WAN is blocked (3 and 4).

Denials of Service (DoS) attacks are aimed at devices and networks with a connection to the
Internet. Their goal is not to steal information, but to disable a device or network so users no longer
have access to network resources. The Device is pre-configured to automatically detect and thwart
all known DoS attacks.
