4.4.4 Firewall
BiGuard 2/10 includes a full Stateful Packet Inspection (SPI) firewall for controlling
Internet access from your LAN, and preventing attacks from hackers. Your router
also acts as a "natural" Internet firewall when using Network Address Translation
(NAT), as all PCs on your LAN will use private IP addresses that cannot be directly
accessed from the Internet. Please see the WAN configuration section for more
details.
You can find five items under the Firewall section: Packet Filter, URL Filter, LAN
MAC Filter, Block WAN Request and Intrusion Detection.
