How to forward RDP port?

RouterOS Beginner Basics

I have the following setup:

aDSL modem that connects to the internet and has a Fwall.
aDSL modem is configured to let 3389 from outside to inside.

MikroTik is configured to have [eth1-public (92.168.20.20) / bridge / eth-private (192.168.10.1)]. The server is 192.168.10.2
I can connect to the internet, and everything works from that side. I have configured fwall as exampled here: http://wiki.mikrotik.com/wiki/How_to_Connect_your_Home_Network_to_xDSL_Line

I need to let 3389 from the internet to the server at local IP 192.168.10.2


Can someone please guide me how to do it? - I don’t understand NAT guide very well.
