Hi Gerry,
Please read the pppd man page for their reasons for the change.
Oversimplified:
It's a security precaution to avoid your machine being used as a relay
without your consent.
It is assumed that a machine with a default route in place is a network
machine. (It's the most common reason for a default route after all.) The
other end of the call has full access to routing through your machine (don't
forget: forward, input and output chains default to accept). So for
accountability, the other end of the connection needs to log into your
system (so transactions can be traced to a valid user id) or you (root) need
to override that setting.
Otherwise, can't you just see the possibilities where "XYZ" company has a
24x7 DSL connection to the net and right before going home "Joe" dials out
to his home machine?
