Q u o t e: Yup i have, but every router i ever had, had only two labels, with start and end port., but without internal, external columns, ip adress and host ip adress.
If all of you know everything about this, why you just tell it?d:
this is patently false, to "forward" a port (send traffic on a specific port through NAT to one internal address) you have to define the internal address at some point. please read a book on computer networking, you don't seem to understand it in any way.
