NetBSD NFS - Ubuntu client mount not working

[Mayuresh <mayuresh%acm.org@localhost>]

On NetBSD 8.0 amd64, my exports look like:

# showmount -e
Exports list on localhost:
/usr/local/ubuntu/fs               127.0.0.1 


I'm running ubuntu VM which is trying to mound the above:

mount -t nfs  10.0.2.2:/usr/local/ubuntu/fs /netbsdfs/
mount.nfs: access denied by server while mounting 10.0.2.2:/usr/local/ubuntu/fs

At this time NetBSD logs show:

Refused mount RPC from host 127.0.0.1 port 60010

I am able to mount the same share on netbsd itself, but not on Linux.
Anything peculiar needed for this to work?
