Cannot connect to 2012 NFS server

Hello

Ive enabled an NFS share on an 2012 R2 server BUT i am unable use it from either debian or redhat linux

I cannot connect at all with v4.1 and down playing to version 3 allows a connect but nothing else

I followed these instructions (http://serverlab.ca/tutorials/windows/storage-file-services/configuring-an-nfs-server-on-windows-server-2012-r2)

Allowing unmapped acces and read/write permissions for all machines

Any ideas ?

thanks

dave
