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: Prevents access from outside your network. The router provides three levels of security
support:
NAT natural firewall: This masks LAN users' IP addresses which is invisible to outside users on the
Internet, making it much more difficult for a hacker to target a machine on your network. This natural
firewall is on when NAT function is enabled.
Firewall Security and Policy (General Settings): Inbound direction of Packet Filter rules to prevent
unauthorized computers or applications accessing your local network from the Internet.
Intrusion Detection: Enable Intrusion Detection to detect, prevent and log malicious attacks.
Access Control: Prevents access from PCs on your local network:
Firewall Security and Policy (General Settings): Outbound direction of Packet Filter rules to
prevent unauthorized computers or applications accessing the Internet.
URL Filter: To block PCs on your local network from unwanted websites.
