Features

NFSv2

It is older but is supported by many systems and was initially operated entirely over UDP.

NFSv3

It has more features, including variable file size and better error reporting, but is not fully compatible with NFSv2 clients.

NFSv4

It includes Kerberos, works through firewalls and on the Internet, no longer requires portmappers, supports ACLs, applies state-based operations, and provides performance improvements and high security. It is also the first version to have a stateful protocol.
