That's what I feared... that's the most difficult problem to fix...
Especially since it happens only sometimes. I've started dhcpcd yesterday
and I just started working again.

I've added that, and I added "iaid 1" to "interface ppp0" because ppp0 was
"changing" the IAID from 70:70:70:30 to 00:00:00:01. Don't know why but if
it wants to be 1 it can be one. :)
