I've noticed the same behavior. It seems that without an external
ifconfig, nothing ever reaches the interface. I've also seen the
"SIOCAIFADDR:Device not configured" message intermittently.
This is so crazy! Some people here are saying it should work without
ifconfig/routed, but I'll be damned if I can get it to do so!

Jay Kuri <jaykuri@oneway.com> sent me the URL for his web page on how to
setup on demand ppp under FreeBSD. Followed his very clear instructions
and it *worked*!
Interestingly enough, his solution involves using a shell script to invoke
ppp *and* do some external fiddling with ifconfig/routing info. Perhaps
some of the ppp experts in this group would like to check it out and
verify that his info is accurate. All I know is that it *works*
(hallelujah!). :-)
See http://pinky.interaccess.com/jay/freebsd/ppp.html (thanks again,
Jay!).
