Thanks Marc for the Reply,
Yup I got it now after I found this explanation of the screen it became clear.

Take traffic entering the chosen interface,
using the specified protocol,
initiated from the specified source,
destinated to the specified destination,
and redirect it to the specified target IP and port.
If you understand the above, then you also understand the power of Pfsense, combined with Alias for Incomming IP's and Ports you can narrow your open port's to the bare minium needed. Most SOHO's and even advanced Firewalls dont have this fine grade filtering they just open the range of ports for all thats happens to hit them.
It is running super stable for days already, so bye bye to my other device. ::)
