The decision for authentication is pppoe. We started pppoed with following option: /usr/libexec/pppoed -dF -e "/usr/sbin/ppp -direct server" xl1 For the ppp we use the following configuration (/etc/ppp/ppp.conf): default: set device PPPoE:xl1 set speed sync set mtu 1492 set mru 1492 server: set cd set login enable proxy set ifaddr 192.168.35.1 set radius /etc/radius.conf enable PAP After starting the pppoed everything is fine. clients are able to connect and communicate with the network.
