I am setting up an OPNsense as security gateway in front of our Proxmox cluster which is hosted on several nodes in 3 GEO locations on OVH Cloud. We need to configure High Availability for the OPNsense appliance using a CARP IP which can be used as WAN interface on both OPNsense virtual machines.
Does OVH Cloud support this CARP IP being shared between two virtual machines running on two separate Proxmox nodes in 2 GEO locations in the OVH Cloud?
If not, what could be a solution for our use case?
