I have followed guides found on google and ubuntu support pages and can get xl2tpd connection up but only under the following conditions:

1 - ADSL model must be configured and connected to the ISP

or

2 - ADSL modem in bridge mode I must have an existing PPPoe connection established.

If neither of the above are active xl2tpd wont trigger pppd and connect to the isp and thus tunnel connection fails to connect to the L2TP server of the ISP.

Am I doing something wrong;
