web-001 on the same hypervisor has correct IPv6 support, we can do the same for Hervil with the /56 trick and the hello trick:

  • The gateway and our /64 IP block belong to a same /56 block
  • OVH route advertisements doesn't reach the server often enough, but if we send a packet to try to reach a IPv6 host, we can receive a configuration
  • Not to use IPv6 for some time and we aren't reachable from outside anymore

All those tricks are already available in roles/core/network unit, so it just need to change pillar/nodes/nodes.sls and NetBox.
