OVH - Proxmox 7 + ipv4 + ipv6 (NAT)

[_gabriel]

in your post #1 you want to do "one ipv4 + multi ipv6" but since your post #6 there are 4 failover ipv4.
there is a confusion for me.

edit : For VM , what is output of "route" ?

 

[lps90]

-1 default ipv4 public ip (multiple LXC's and VM's using the same ipv4 with different internal ips and different ports)
-4 or more failover ips
-All machines with a different ipv6 public ips
Everything using NAT.
This is basically what i want.
