This is exactly what I'm doing.  Must be something else going on here.

What I don't understand is, I can ssh to a Linux box inside this 
network, that is through this same smoothwall.  From there, I can run 
rdesktop to that machine and display it back on my network.  I do 
understand that all this is happing in the ssh tunnel, but this does 
tell me that the XP box I'm trying to connect to is accepting 
connections from rdesktop.

I removed the references on the 'sending smoothwall', still no joy. :(
