Firewall and Access Control

using NAT, the router acts as a "natural" Internet firewall, as all PCs on your LAN will have their
own private IP addresses which is 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.
