1: Is the nfs port open on ipv6? Use "ss -ln | grep :2049" and look
for a listening port with an IPv6 address, like:
tcp LISTEN 0 64 [::]:2049 [::]:*
2: Does your firewall allow access to port 2049 on IPv6? Use
"firewall-cmd --list-services" and look for "nfs", or use "ip6tables
-L" and look for the input chain for your default zone (possibly
IN_public_allow).
root@MyCloudEX2Ultra ~ # ss -ln | grep :2049
-sh: ss: not found
In that case you probably only have busybox's netstat, and I don't know
what flags it supports. Try "netstat -tln" and if that doesn't work
maybe "netstat -ln" to get a list of the listening ports.
root@MyCloudEX2Ultra ~ # ip6tables -L

The system's input chain should allow NFS traffic on IPv6 by virtue of
the ACCEPT policy. That suggests that the NFS service isn't listening
on an IPv6 network socket.
