What Iptables rules need I to forward a windows remote desktop connection?

"just port foward 3389 tcp and udp to the computer that has the remote desktop enabled. Then figuar out you external ip by going to a speedtesting website. Once done then all you need to get to your desktop is to type your external or GLOBAL ip address into a remote desktop terminal. user/password. done.

to port foward 3389 you need to enter your router and add that rule. there is no routing table you need to add. just that rule."
