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.
