Perhaps I understand wrong. Please see below:


=46rom "http://www.ietf.org/rfc/rfc3530.txt"

3.1.  Ports and Transports

   Historically, NFS version 2 and version 3 servers have resided on
   port 2049.  The registered port 2049 [RFC3232] for the NFS protocol
   should be the default configuration.  Using the registered port for
   NFS services means the NFS client will not need to use the RPC
   binding protocols as described in [RFC1833]; this will allow NFS to
   transit firewalls.

   Where an NFS version 4 implementation supports operation over the IP
   network protocol, the supported transports between NFS and IP MUST be
   among the IETF-approved congestion control transport protocols, which
   include TCP and SCTP.  To enhance the possibilities for
   interoperability, an NFS version 4 implementation MUST support
   operation over the TCP transport protocol, at least until such time
   as a standards track RFC revises this requirement to use a different
   IETF-approved congestion control transport protocol.
