it was not forgot, it is on my todo list ...

unfortunately I have no test systems available
ATM to test an nfs setup, but I will try to
recreate the setup with a QEMU network shortly

in general, the answers to the following questions
could be very helpful:

 - what NFS version and tcp or udp? 
 - what is the actual error you get? 
 - tcpdump of the ongoing negotiation? 
 - logs on both, client and filer with the
   appropriate sysctl debug options enabled
   sunrpc.nfsd_debug (filer)
   sunrpc.nfs_debug (client)
   sunrpc.rpc_debug (both)

TIA,
Herbert
