EciAdsl driver (version 0.8 or more) is compatible with Free dégroupé.
Changes to do in driver config:
- in /etc/eciadsl/eciadsl.conf (with eciconf.sh): MODE=VCM_RFC1483_ROUTED_IP, STATIC_IP=yes, VPI=8, VCI=36, setup static IP address and gateway (given by Free),
- in /etc/ppp/peers/adsl: remove line with username.
