Remote Desktop Connection to Internal Servers

Hi guys,

I have this setup on my F5 lab I would like to share. I have an external interface on the F5 facing the internet, I have another interface on a switch connected to a Sophos Firewall which is on a 172.16.16.0/24 network, then I have another interface that faces my internal servers on 10.2.0.0/24 network. Successfully I have been able to set up the F5 such that any host sitting on the 172.16.16.0/24 network can ping my servers on 10.2.0.0/24 network. What is the bottle neck now isz I have been trying to allow remote desktop connection from the host on 172.16.16.0/24 network to the servers on 10.2.0.0/24 network but it seems not to be working. I tried setting up a standard Virtual server on the F5 on port 3389 and all protocols, that doesn't work. Then I tried setting up a forwarding IP Virtual server on port 3389 and all protocols, that doesn't work too. The error message for both cases is remote computer might be turned off, or may not be on the network or may not be enabled. I have checked all cases on the remote computer 10.2.0.44 and they are all up. What am I not doing right ?
