I understand what you are saying, but the setup works perfectly about  
75% of the time.

This is what I mean by 'If it failed consistently then I'd have some  
idea of what to fix'.

Last night I was online, got offline, couldn't get back on.
This morning (after doing nothing more than waiting 6 hours since I  
tried the last time), it worked on the first try.

Here's the 'ifconfig' information from the FreeBSD machine when I am  
dialed in:
