This a NAT router so all ports will be open. The screen shot you attached is for port forwarding of incoming ports to a specific ip address.

The port scan is trying to see which ports it gets a response from so forwarding ports is not enough, you need to have something on the PC's listening to the ports and responding to the probe, otherwise they will be reported as stealth.

You can see what ports are active on a PC by opening a command prompt and typing "netstat -an"

If you want to block ports on specific machines you need to use a local software firewall.
