Firewall
The router automatically provides a firewall. Unless you configure the router to the contrary, the router does not respond to unsolicited
incoming requests on any port, thereby making your LAN invisible to cyber attackers.
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 ways of opening the firewall to address the needs of specific types of applications.

Port Forwarding Rules
A port forwarding rule allows traffic from the
Internet to reach a computer on the inside of
your network. For example, a port forwarding
rule might be used to run a Web server.
Exercise caution when adding new rules
as they impact the security of your network.
