Thanks. We were able to fix our firewall so things work properly now. 
The problem is that this is "insidious" since it is not immediately 
apparent what the problem is especially since it tends to work with all 
other OSes except Linux with 2.6.6+.

I will note this on the bug I submitted and close it.

Thanks a lot,
