Right.

NO! that doesn't make sense. In http/https connections, the source port
is an arbitrary high port, and the _destination_ port is 80/443.

In order to forward the https trafic either change "80" to "443" end up 
with 4 lines, 2 PREROUTING and 2 POSTROUTING or use the multiport 
extension: "-m multiport --dports 80,443" in both lines of the original 
example.
