I'm sorry for wasting everyone's (and also my own) time.  Who would have 
guessed that a faulty ipf setup would result in a 'no route to host' 
error?

Yes, the problem was IPF -- apparently, I was not allowing traffic out on 
the internal interface.  This is unusual for a number of reasons, in 
particular:
  - I basically copied and pasted the ipf.rules generating script from my 
home system, where I have no problems;
  - the error message is not at all indicative of an ipf problem.  I view 
this as possibly a reportable bug.  Perhaps those of you up to your 
shoulders in grease from BSD internals can illuminate my confusion, but 
"no route to host" when a perfectly suitable route exists in the routing 
table seems a misnomer at best.  What do you think?

I still don't have the second NIC working, but at least I'm to the point 
of timeout errors instead of route rejections.  The current problem could 
also be in the 'dsl router' I'm using, as well.

By the way, both bpf and the miibus are in the kernel.

Thanks again for reading.
