Bonjour,
J'ai configuré deux machines virtuelles sous Debian Stretch afin d'étudier PPPoE.
Ces deux machines ont une interface Ethernet ens9 dédiée au PPPoE.
Je suis totalement novice sur PPPoE donc je me sens parfaitement capable des pires erreurs et énormités.
Le serveur PPPoE est lancé avec une commande manuelle:
pppoe-server -C isp -L 192.168.4.254 -p /etc/ppp/allip -I ens9
Le client PPPoE est lancé avec une commande:
pon dsl-provider
Voici les logs de mon serveur PPPoE:
