Si IPFO, voici l'exemple de config du VT de mon blog (IP publiques donc) pour OVH/SoYouStart :
# UNCONFIGURED INTERFACES
# remove the above line if you edit this file
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet static
address 158.69.161.16
netmask 255.255.255.255
# --- BEGIN PVE ---
post-up ip route add <gateway_IPv4> dev eth0
post-up ip route add default via <gateway_IPv4> dev eth0
pre-down ip route del default via <gateway_IPv4> dev eth0
pre-down ip route del <gateway_IPv4> dev eth0
# --- END PVE ---
auto eth1
iface eth1 inet dhcp
iface eth0 inet6 static
address 2607:5300:120:462::4
netmask 64
# --- BEGIN PVE ---
post-up ip route add <gateway_IPv6> dev eth0
post-up ip route add default via <gateway_IPv6> dev eth0
pre-down ip route del default via <gateway_IPv6> dev eth0
pre-down ip route del <gateway_IPv6> dev eth0
# --- END PVE ---
