NM and DSL pppoe environment

[Paul Ionescu <i_p_a_u_l yahoo com>]

Hi list,

I have a F7 installed on a computer with pppoe DSL link to internet.
I don't know how to configure NM to have net connectivity via
DSL/PPPeE without human intervention.

If the NM service is started I don't have net access because I am losing
the default gateway trough ppp0 as NM tries to configure the eth0
interface.

If the NM service is not started, interfaces eth0 and ppp0 are initialized
at boot time and I have net connectivity via DSL/PPPoE/ppp0.

Any idea how to solve this ?
Thanks.
