Bonjour,

Je souhaite envoyé des requêtes http avec l'ip failover. J'ai ajouté l'ip failover en suivant le guide donné dans l'email.

http://guides.ovh.com/AjouterAliasIp/

Cependant quand j’exécute une requête curl en précisant l'interface c'est l'ip du serveur qui est utilisé.

Voici ma configuration pour l'interfaces, je suis sous debian 8.

L'Ip du serveur est indiqué par MON.IP.VPS.SERVEUR, elle commence par 51.255.42.XXX.

auto eth0
iface eth0 inet dhcp
        address MON.IP.VPS.SERVEUR
        netmask 255.255.255.0
        broadcast 51.255.42.255
        network 51.255.42.0
        gateway 51.255.42.254
        post-up /sbin/ifconfig eth0:0 MON.IP.FAIL.OVER netmask 255.255.255.255 broadcast MON.IP.FAIL.OVER
        post-down /sbin/ifconfig eth0:0 down

Voici la requete curl
