Setting up RDP between 2 internal networks

My issue is simple I think but I have been unable to come up with a solution.   We have 2 seperate networks in our office.   A production network (192.168.254.0/24) and a testing network (192.168.250.0/24)  No connection between them at all.  The 192.168.250 network has no internet access and really is just 4 servers connected to a switch so they can talk to each other.   I woud like the two networks to be able to access each other via RDP (tcp/3389) only.  I setup a ASA 5505 (ver 8.2.5) between the two networks with the 192.168.254.0 on the inside interface and the 192.168.250.0 on the outside interface.   Factory defaulted the ASA to be sure it is clean and ran through the setup.  see the config below.   To start I want only 192.168.254.154 to be able to RDP to 192.168.250.100.   As I would expect that works just fine,   Inside to outside.  No problem.  Next I try and setup a access rule to alllow 192.16.250.100 to RDP to 192.168.254.154.  ( outside in) and nothing I have done for the last 2 weeks seems to work.  I setup port forwarding just as I have done in the past for email and other things and nothing will work.   Infact as soon as I do the RDP stops inside to ouside. 

The config below is a clean one with no extras. 

Any ideas????
