- Is it the same setup? Maybe you forgot something?
- Bridged or routed?
  It looks like an OVH setup:
  * Bridged:
    + Did you make sure they all have valid MAC addresses correctly assigned to their
      IPv_4_ address?
  * Routed:
    + Did you add ndp neighbor proxy entries for them all (or are you using ndppd)?

You should check with `tcpdump` where the packets or their responses get lost.
