In that case just stacking of ng_ppp (or ng_pppoe, what's the difference?) on top of ng_atm and enabling the right VCC should do it. Well, you also need to get rid of the LLC/SNAP header in between (I'm think of creating an ng_llc node). This configuration stuff could be built in into atmconfig. If someone is able to test this (has an xDSL mode, a connection and a driver for the modem) I would try to help to get this up. harti -- harti brandt, http://www.fokus.fraunhofer.de/research/cc/cats/employees/hartmut.brandt/private brandt@fokus.fraunhofer.de, harti@freebsd.org
