Firewall Rules

You may want specify inbound or outbound access control to allow/deny sources (or
Internet IP addresses) to your network from the Internet or from computers or devices
on your network to the Internet. Firewall rules may allow for more granular control of
specific inbound and outbound access between your network and the Internet. It is
