I am not an IT manager, but I am trying to set up an additional route through our router for RDP using NAT. I have successfully set up two other workstations doing this, but the third is not working. I set the first two up by forwarding the public IP address on a port to the internal IP address on the RDP port 3389. The two other workstations are set up this way and work great. The third is set up the same way, but I cannot get in from outside. I can RDP to the workstation from inside the local network. Our network has no it manager.

Hello,
from what I can see in your non-working configuration, you are using the same address space on two different interfaces:
interface FastEthernet0/0
ip address 63.245.89.83 255.255.255.248
interface FastEthernet1/0
description connected to metrored
ip address 63.245.89.82 255.255.255.248
The router should actually generate an error message telling you that there is an overlapping address space once you try and 'no shut' the FastEthernet1/0 interface.
