4.4.2.2 IP/Port Filtering
IP/Port filtering is a security tool that allows you to configure internet
restrictions for specified devices based on IP addresses and port number(s).
IP/Port filtering is disabled by default so it must be enabled before filters can be
configured.
If you choose the “Allowed” option for default policy, packets routed
to the IP address specified in the rules will be dropped and vice versa. In short
the “Allowed” option is creating a blacklist and the “Dropped” option is creating a
whitelist.
