Maybe it would help other people offer some help if you included your
ifupdown configuration, and also the ifconfig and ping output that
concerns you? I would probably check for bugs on ifupdown pkg page also.
I stopped using ifconfig a couple yrs ago. From what I recall it always
shows the iface without an IP when it is down? I never used ifconfig to
set or manipulate interfaces, but I think it's probably not compatible
with ifupdown?
I think some ip output might be helpful also.
