Hi,
It sounds like you haven't done a
set ifaddr something hisnumber
in your config. Without this, if the peer asks for 0.0.0.0, ppp will
just say ``yeah, fine, I don't know any better''. Make ``hisnumber''
whatever you want him to use and make ``something'' whatever you want
to use locally - probably just your NIC iface IP address (dups are ok
as long as only one is a broadcast device).
