Oh, OK.  When you said "through a firewall", I just figured you meant 
across the Internet.  My mistake.  Sounds like you've got a pretty 
complex setup there!  :-)

What I would do is get the IP address of your thin client and look to 
see what traffic is attempting to pass through the firewall to/from that 
IP address.  Then, when it shows up at the firewall (getting blocked, I 
presume), you can just open up that type of traffic, and you should be 
good to go.  How far are your clients getting in the boot process?
