7.1.1

Firewall

The term "firewall" comes from a construction technique designed to prevent the
spread of fire from one room to another. Similarly, your CODA-4x8x'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.
