ICMP is not blocked. I added some logging to the server firewall and it
looks like with the new version of nfs-common the client is attempting
to talk to the server's portmapper, the old version does not attempt
this. The portmapper port is not open since as I understand it,
portmapper is not required for NFSv4.
