I'm trying to configure multiple IP Failover on the same VM behing Proxmox VE.

I've got these IP : IP1, IP2 and IP3. IP1 is the main one. I've configured in Proxmox these IP in veth with theses infos :

• Name : eth0, Mac : Virtual_Mac_Ip1


• Name : eth1, Mac : Virtual_Mac_Ip2


• Name : eth2, Mac : Virtual_Mac_Ip3

And I've modify my /etc/network/interfaces file in my VM with this :

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet static
 address IP_1
 netmask 255.255.255.255
 broadcast IP_1
 post-up route add MAIN_IP dev eth0
 post-up route add default gw MAIN_IP
 post-down route del MAIN_IP dev eth0
 post-down route del default gw MAIN_IP


auto eth1
iface eth1 inet static
 address IP_2
 netmask 255.255.255.255
 broadcast IP_2
 post-up route add MAIN_IP dev eth1
 post-up route add default gw MAIN_IP
 post-down route del MAIN_IP dev eth1
 post-down route del default gw MAIN_IP

auto eth2
iface eth2 inet static
 address IP_3
 netmask 255.255.255.255
 broadcast IP_3
 post-up route add MAIN_IP dev eth2
 post-up route add default gw MAIN_IP
 post-down route del MAIN_IP dev eth2
 post-down route del default gw MAIN_IP

With this configuration, I can't ping none of my IP. If a configure in /etc/network/interfaces only one IP (eth0, eth1 or eth2), this one works !

What is wrong with that ?

Try to change the netmask from all 255.255.255.255 to your actual subnet number, so if you're using a 24bit schema, change it to 255.255.255.0 only.

Hope this works.
