6.4 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.
6.4.1 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.
Click Add to create a new port forwarding rule, or select an
existing rule and click Edit.
Add/Edit Port Forwarding Rule
Name: Name your rule.
Use Port Range: Changes the selection options to allow
you to input a range of ports (if desired).
Internet Port(s): The port number(s) as you want it
defined on the Internet. Typically these will be the same
as the local port numbers, but they do not have to be.
These numbers will be mapped to the local port numbers.
Local Computer: Select the IP address of an attached
device from the dropdown menu, or manually input the IP address of a device.
