TFTP
From Freenas
Trivial File Transfer Protocol (TFTP) is a light-weight version of FTP usually used to transfer configuration or boot files between machines, such as routers, in a local environment. TFTP provides an extremely limited set of commands and provides no authentication.
If the FreeNAS® system will be used to store images and configuration files for the network's devices, configure and start the TFTP service. Starting the TFTP service will open UDP port 69.
NOTE: in versions of FreeNAS® prior to 8.3.0, TFTP is limited to a maximum file size of 32MB.
Figure 8.15a shows the TFTP configuration screen and Table 8.15a summarizes the available options:
