In case you missed it, OVH enabled VAC on port 123 packets to prevent their
network from assisting in DDoS attacks utilizing NTP amp.

I run my pool server behind OVH and haven't seen any issues yet. They
appear to only be filtering monlist commands, yet allowing queries and
peers. I checked openntpproject for the /24 I'm on (192.95.20.208) and
there's no results, but, on other similar networks there are still
offenders
