Firewall and Access Control
Your router includes a full SPI (Stateful Packet Inspection) firewall for Internet access controlling from
your LAN. This feature also protects your system from being attacked by hackers. When using NAT,
the router acts as a "natural" Internet firewall, as all PCs on your LAN will have their own private IP
addresses which are not directly accessible from the Internet. The router provides three levels of
security support.
NAT natural firewall: This masks LAN users' IP addresses which are invisible to users on the
Internet, thus making it more difficult for a hacker to target a machine on your network. This natural
firewall is turned on when NAT function is enabled.

unauthorized computers or applications to access your local network from the Internet.
