Network File System (NFS) is a protocol for sharing files on a network. Before configuring this service, you should first create your Unix (NFS) Shares. After configuring this service, go to Services → Control Panel to start the service.

Starting this service will open the following ports on the FreeNAS® system:

  • TCP and UDP 111 (used by rpcbind)
  • TCP 2049 (used by nfsd)

Additionally, mountd and rpcbind will each bind to a randomly available UDP port.

Figure 8.8a shows the configuration screen and Table 8.8a summarizes the configuration options for the NFS service:
