Is there a way to tell ipv6 mount to use prot UDP port 37811?
You can try....
[egreshko@meimei ~]$ sudo mount -t nfs -o vers=3 [2001:b030:112f:2::53]:/home/egreshko /mnt
[egreshko@meimei ~]$ df -T | grep nfs
nas:/volume1/aux nfs4 5621463168 1996292608 3625170560 36% /aux
nas:/volume1/misty nfs4 5621463168 1996292608 3625170560 36% /home/egreshko/misty
[2001:b030:112f:2::53]:/home/egreshko nfs 32504832 17629184 14537216 55% /mnt
Have you determined why nfs V4 isn't available?
Oh, BTW, I should have sent the -v version.
[egreshko@meimei ~]$ sudo mount -t nfs -o vers=3 -v [2001:b030:112f:2::53]:/home/egreshko /mnt

You really should post examples of IPv6 test which fail and not IPv4 examples which succeed.
