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 ( and a testing network (  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 on the inside interface and the 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 to be able to RDP to   As I would expect that works just fine,   Inside to outside.  No problem.  Next I try and setup a access rule to alllow to RDP to  ( 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????
