RDP ending in SYN_RCVD state

Hello Everyone!
The situation:
A: workstation in Company, behind a D-Link firewall, NATed, port 3389
allowed outwards on the firewall for this computer.
B: home computer, behind an ADSL router, NATed, port 3389 on the
router is forwarded to my computer.
C: a web server on the internet, with its own IP number.
All computers are Windows.
So there is NAT on both ends of the line between A and B.
I would like to connect from my Company (A) to my home computer (B)
via RDP (Remote Desktop). The connection is never established. When I
log into the D-link company firewall, I see that the connection got
stucked in a SYN_RCVD state.
I tried to RDP from A to C: SUCCESS, the company firewall let me out.
Then, while being in C, I started another RDP within C, to my home
computer (B). SUCCESS. So the home network and computer let me in.
Any ideas? I believe I should change something in the company
firewall, but I have no idea, what. I can RDP to non-NATed computers,
but no go, if the target computer is NAT-ed, even if the other end is
configured prolerly.
Thank you for your help in advance.
Best regards,
Laszlo
