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. Besides, when using NAT, the
router acts as a "natural" Internet firewall, as all PCs on your LAN will use private IP addresses
that cannot be directly accessed from the Internet.
Firewall: Prevent outsiders from accessing your local network. 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.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to
prevent unauthorized computers or applications to access your local network from the Internet.

Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to
prevent unauthorized computers or applications from accessing the Internet.
