Destination Port Filtering: The destination port filtering enables you to restrict certain ports of data
packets from your local network to Internet through KWG-O6020-I. Use of such filters can be helpful in
securing or restricting your local network.

Port Forwarding:
The port forwarding allows you to automatically redirect common network services
to a specific machine behind the NAT firewall. These settings are only necessary if you wish to host
some sort of server like a web server or mail server on the private local network behind
KWG-O6020-I’s NAT firewall.
