Cisco 1841 Outside TO Inside Port Translation NAT

I have a cisco 1841, here is a snippit of my config..

ip nat inside source static tcp 10.20.36.12 3389 interface FastEthernet0/1 4389

ip nat inside source route-map NAT interface FastEthernet0/1 overload

ip nat inside source static tcp 10.20.36.249 22 interface FastEthernet0/1 22

ip nat inside source static tcp 10.20.36.249 23 interface FastEthernet0/1 23

                  

ip nat inside source static tcp 10.20.36.12 3389 interface FastEthernet0/1 4389

ip nat inside source route-map NAT interface FastEthernet0/1 overload

ip nat inside source static tcp 10.20.36.249 22 interface FastEthernet0/1 22

ip nat inside source static tcp 10.20.36.249 23 interface FastEthernet0/1 23

I would like to open the terminal services port 3389 on 10.20.36.12 FROM OUTSIDE using port 4389.

It woud seem that I have the proper syntax? But when trying to change the direction to FROM OUTSIDE TO INSIDE, i am unable to. have I missed something critical?

Should I be holding a WRONG WAY sign..lol

Is fe0/1 the external intrface you will be coming in on. If so then your config is good. If not then simply replace fe0/1 with your external interface and job done.

Hi,

I agree with Andrew and don't see any problem with your NAT config. Could you post your show run and show ip nat translation | inc 10.20.36.12? Kindly remove sensitive data.
