====WebNFS====

{{Main|WebNFS}}

[[WebNFS]] was an extension to NFSv2 and NFSv3 allowing it to function behind restrictive firewalls without the complexity of Portmap and MOUNT protocols. WebNFS had a fixed [[List of TCP and UDP port numbers|TCP/UDP port number]] (2049), and instead of requiring the client to contact the MOUNT RPC service to determine the initial filehandle of every filesystem, it introduced the concept of a ''public filehandle'' (null for NFSv2, zero-length for NFSv3) which could be used as the starting point. Both of those changes have later been incorporated into NFSv4.
