Debian 9 OVH Bridge Network Configuration
When you run VPS on OVH network behind bridge network, you need to create VMAC for each IP and assign to your network card.
Once this is done, you need to use following network configuration in your /etc/network/inferfaces file.

auto lo ens18 iface lo inet loopback auto ens18 iface ens18 inet static address FAILOVER_IP netmask 255.255.255.255 broadcast FAILOVER_IP post-up ip route add GATEWAY_IP dev ens18 post-up ip route add default via GATEWAY_IP dev ens18 pre-down ip route del GATEWAY_IP dev ens18 pre-down ip route del default via GATEWAY_IP dev ens18 |
FAILOVER_IP = the IP you will be using for the virual machine.
GATEWAY_IP = IP of the Host server with last digits replaced by 254. If your servers main IP is XX.YY.ZZ.100, then Your GATEWAY_IP is XX.YY.ZZ.254
Here is an example config file i use in one of my VPS

I made a pull request to OVH as OVH documentation use route command, that is deprecated in Debian 9 and Ubuntu 18.04. We need to use “ip route” command instead of “route” command.
