Vista, cygwin sshd, Remote Desktop

Hi community,

I've a problem with a special configuration.
Vista Ultimate, cygwin sshd installed
SSH tunnel (configured to forward RDP port 3389) and Remote Desktop
(through tunnel) are working as long as the Windows Firewall is turned
off.
If I switch it on the SSH tunnel collapses as soon as the Remote
Desktop session is established.
So, SSH alone is working with an active Firewall.
RDP is working with active firewall.
Together they are not working

SSHD error log (highest debug level) shows "write failed", but nothing
more. Windows Firewall log shows nothing interesting either.

Anybody with a hint out there?

greetings,
CyberMCM
