Thanks, that did it.  I tried adjusting my MTU before, but did not 
consider the MTU of the FW; which happens to be set to 1450.  So setting 
the MTU of problematic machine to 1450, and not 1454, fixed my issues.

I guess the only other point worth mentioning is the fact that with fbsd 
4.11 works fine with an MTU of 1500.  I'm not sure, but could this have 
something to do with DF bit not being set correctly?
