4.1.1

FIREWALL

The term "firewall" comes from a construction technique designed to prevent the
spread of fire from one room to another. Similarly, your CGN's firewall prevents
intrusion attempts and other undesirable activity originating from the WAN, keeping
the computers on your LAN safe. You can also use filtering techniques to specify the
computers and other devices you want to allow on the LAN, and prevent certain traffic
from going from the LAN to the WAN.
