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, 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.
When using Virtual Servers, your PCs will be exposed at a certain degree specified in your Virtual Server settings when the ports specified are opened in your firewall packet filter settings.
•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: Allow the filtering of unauthorized users from other networks or WAN, unwanted websites & malicious programs from accessing the local network.
