6.3.10 Firewall

• The device provides a tight firewall by virtue of the way NAT works. Unless you
configure the router to the contrary, the NAT does not respond to unsolicited incoming
requests on any port, thereby making your LAN invisible to Internet cyber attacks.
However, some network applications cannot run with a tight firewall. Those
applications need to selectively open ports in the firewall to function correctly. The
options on this page control several ways of opening the firewall to address the needs
of specific types of applications.
