4.3.4 Firewall

Firewall and Access Control

Your router includes a full SPI (Stateful Packet Inspection) firewall for controlling Internet

access from your LAN, as well as helping to prevent attacks from hackers. In addition to this,

when using NAT (Network Address Translation) the router acts as a “natural” Internet

firewall, since all PCs on your LAN use private IP addresses that cannot be directly

accessed from the Internet. See the

WAN

configuration section for more details on NAT.
