Tout marche tres bien avec l'interface un dev tun dans la configuration
du serveur, mais je veux pourvoir être capable d'utiliser un serveur
DHCP extrerne.
Pour cela sur le site de openvpn, il est dit qu'il faut utiliser une interface tap.
Je peux creer une interface tap0 avec openvpn
Je peux creer avec brctl un bridge br0 et y inclure des interfaces.
Premier probleme:
Des que je rajoute une interface ethx a br0 je ne suis plus capable de
pinguer le reseau deriere et le reseau ne peut plus me piguer !
eth1 10.40.251.1/24
tap0 0.0.0.0/32
br0 10.40.251.10/24
Deuxieme probleme:
lorsque ke lance l'ami Openvpn j'obtiens ca
