Dear Freddijanto
Thanks for your reply. It fixed my problem straight away.
Why on earth don't the default nfs client options set in /etc/rc.conf
as shipped with FreeBSD specify that TCP mode is required for the
client. I spent several frustrating days banging my head against an
NFS brick-wall over this one ! Well I am enlightened now.
Thanks
Graeme

Since you are using tcp nfs server (flag -u -t 4), you must use
"mount_nfs -T ........" instead of "mount -t nfs ....."
